Handover ad-Hoc
Copenhagen, Denmark
6 - 8 March 2000

Draft Meeting report

1	Opening of the meeting
Mr. Bengt Persson on behalf of Ericsson welcomed the delegates to Copenhagen. The meeting was chaired by Mr. N. Andersen (Motorola), and the Secretary was P. Usai (MCC). The Chairman set the target to complete the subject of Handover by next SMG2 Plenary in early April

2	Approval of the Agenda
The Agenda in Tdoc B01/00 was approved. The Tdocs were allocated to Agenda Items.
3	Letters / Reports from other groups
Tdoc B40/00 “Liaison Statement on UMTS synchronisation channel detection” from 3GPP TSG RAN was presented by Ms. S. Boumendil. The document confirmed that it is the common understanding in RAN WG1 that synchronisation can be acquired unambiguously within 5 ms window. Comments: then, SMG2 also asked how often the synchronisation information needs to be reconfirmed. RAN WG1 could not provide this information as it is strongly dependent on the radio conditions, system deployment, etc. Assumption from the LS would be that UTRAN frequencies could be monitored, depending on the MS capability. A discussion took place on the procedure/process to detect, synchronise, measure and report the performance in the detected cell, then how long would be required to detect and measure a second cell.
Conclusion: the LS confirmed how to detect a suitable cell, and synchronise, but then it was unclear how to proceed from that point on.

4	Idle mode and cell (re)-selection
Tdoc B11/00 “GSM to 3G handovers: Radio Interface Signalling Concept” from Vodafone Airtouch, was presented by Mr. C. Arzelier. The threshold concept in idle mode to switch (slow or fast) GSM/UMTS in co-located cells was questioned, depending on the scenario and network planning. More questions on the signalling side were left for the appropriate agenda item.
BSIC System Information 5, 5-bis, 5-ter message mechanism was clarified it would be sent once at a time, repeating eventually the indication of the same frequency in each BSIC; B. Persson asked how to index each enhanced measurement report; also the need to receive all BSIC information was felt a possible drawback in such case. Chairman asked why SI 5 should not be changed in dedicated mode.
Other questions were raised on the use of the Layer 2 (never used in practice, although described in the specifications GSM 04.06 and 04.07), on SI 5 Delta (if used in both idle/dedicated modes, and on “Time Difference” case, how often sent/refreshed, and with what accuracy/resolution).

Tdoc B31/00 “Mapping between GSM RXLEV and CPICH Ec/No” from Ericsson, was presented by Mr. D. Rylander. To be able to map between GSM RSSI and CPICH Ec/No a common quantity that is possible to estimate and defines the “goodness” of the cells regardless the Radio Access technology must be defined. In this paper the “Probability for block errors when receiving BCCH” is proposed to be the common quantity used for representing the "goodness" of a cell. It is proposed that a look up table based mapping based on equal BCCH BLER is further investigated.
Nortel Networks, Siemens and Vodafone AirTouch asked some clarifications on the proposal based on the following idea: for a cell of other radio access technology, RXLEV is replaced by the relevant mapped quality measure for that radio access technology resulting on BLER considerations + an offset. The SMG2 Chairman, as well as the presenter, made some examples of possible cases of occurrence. The SMG2 Chairman stressed the need to find a solution, more or less perfect for Release 99 systems. The mechanisms based on absolute thresholds and mapping could fit to decide for the handover GSM/UMTS, if the parameters needed to take decision are provided.

Tdoc B30/00 “Intersystem cell selection and handover (CR-0508-A242 rev 2)” from Ericsson, was presented by Mr. B. Persson. The document contained the procedure description for Inter System handover and Intersystem cell re-selection. What should be reported and how to report was debated. Questions on terminology and access priority to different RATs were made by Nortel Networks. The SMG2 Chairman asked to put the references in the document in the specified way (e.g. at least replacing 3GPP by 3G). A. El-Saigh asked the text be reformulated in a different way, since it could be interpreted as in favour of a certain RAT, not necessarily the one used by the operator when more RAT are enough well suited. The Chairman pointed out that the mapping would be dependent on whether the criterion for the selection is GSM-cell based or UMTS-cell based, unless a rather general offset is found (to be checked whether it works in practice). Mr. C. Arzelier pointed out, in Sect. 4.3.7, that, if multiple non-GSM RATs are all available, this would need a certain rule to prioritise what measurements are to be performed an on which of the available RATs first. Mr. A. El-Saigh made a number of comments on the definitions and terminology adopted, and the SMG2 Chairman asked to formulate the text in a very precise manner, to avoid misunderstandings and/or possibility of multiple interpretations based on linked text in other specifications. MultiRAT reporting was requested to be increased (more than three UMTS cells, e.g. at least six). The Chairman observed this would be important only if the cells are fairly equal, considering the case of multiple frequencies allowed (up to 4 in UMTS) and the time allowed to report (5s for each frequency), since the conditions could change, for moving MS in the traffic. It was commented that the addition of UMTS cells would increase the number of reported parameters and the priorities for the measurements should be set as well. Moreover, it was commented this would complicate the MSs, since all combinations of GSM/RATs would need to be supported.
Mr. B. Persson observed that in practice no more that 4 reports would be possible. Moreover, according to the text in section 7.2, the principle is set that only if resources are available, a multi mode MS may use the search frames, which are not required for BSIC decoding, to identify and measure cells belonging to other radio access technologies. It was proposed to allow the operator to force the MS to spend some priority for measuring at least one UMTS cell, if he wants to do that.
This was felt more relevant for the full-rate channel case. TDD compatibility was requested to be safeguarded as well (whenever the case occurred in the text). Sections 6.4 and 6.6.1 would also need some changes. as well.

Conclusion: A minimum set of scenarios should be defined to set the requirements for the detection, measurements and reporting. The basic assumption was that the same criteria as in GSM shall be used for cell selection and for that reason a (linear) mapping function should be used in order to compare the UTRAN and the GSM measurements. For idle mode it was assumed that the MS shall read the parameters from the UTRAN neighbour cell as in GSM. For connected mode and for GPRS (PBCCH) all parameters are supposed to be broadcast in the serving cell.
The CR to GSM 05.08 will be re-drafted taking into account the comments made, and discussed on the SMG2 reflector.

Tdoc B32/00 “GSM to UMTS cell selection” from Ericsson, was WITHDRAWN.
Tdoc B35/00 “Measurement Order - Idle mode” from Ericsson/Siemens, was presented by Mr. P. Edlund. The requirement values should be put, as usual, in GSM 05.08 instead than in 04.18. Examples should cover both limits of the range (positive as well as negative). Moreover, a discussion took place on whether one case should be made mandatory where UMTS cell would be measured in spite of the fact no UMTS cells are present in the neighbour list (e.g. by measuring the frequency and scrambling mode). Mode of implementation of such possibility was requested to be left rather open to different options for operators. GSM and multiple RATs (different from UMTS) were requested to be allowed/considered as well (it would request to use another bit for this info).
Other pieces of information could be needed as well to the purpose, apart frequencies and scrambling code, e.g. barred/not barred cell. Then, some further study would be needed, and an offset for FDD and TDD modes could be requested, etc.
Conclusion: Ericsson/Siemens were requested to check the consistency of their proposal with the comments made.

5	Handover GSM to 3G for circuit switched connections
2, 24
Tdoc B02/00 “GSM 10.89 GSM to Other Systems Handover' v0.0.2” was presented by Mr. K. Isaacs. Comments: Synchronisation between GSM and UTRAN should be possible during a GSM idle frame ( i.e. within 5ms ) could be interpreted one frame is always enough. On the number of GSM/UMTS cells on which the measurement report should be granted, the interpretation was debated about the (minimum) number of measurements in the GSM access technology (900/1800 band) that should be reported. The equal priority principle for the serving band and other bands (GSM/UMTS) was debated, for single mode and dual mode terminals. The ”offset” between GSM900 and GSM1800 MHz and RATx, if different per frequency band, could allow to differentiate among the serving band and the other bands /technologies. The title of the document was requested to be clarified whether it should refer to handover only or other aspects as well. 
The document was requested to be updated, taking into account the comments given, within the end of this meeting (which was felt possible if written contributions are provided). Handover failure text was requested to be improved.
Tdoc 24/00 rev1” Concept for GSM to UMTS in release 99”, from Ericsson, was presented by Mr. P. Edlund. The Source of the document was clarified to be Ericsson only (Source: included by mistake other Companies). Prioritisation of a number of UMTS neighbours was felt relevant. Power consumption parameters were proposed to be optional. The decisions taken on GSM 10.89 and GSM 05.08 will be reflected in the updated versions of the documents.

Tdoc B09/00 “Enhanced Measurement Reporting with UMTS neighbours” from Nokia, was presented by Mr. L. Friman. Comments: On page 2 the revert to normal measurement reporting was requested to be clarified (brackets to be removed). Handover failure was not described. On page 8, delay and hysteresis parameters were requested to be clarified what these parameters are useful for. [] were requested to be put for undefined list items. Further comments will be given off-line to Nokia. The proposal was felt flexible (which implies a price to be paid); the size of the sent info was requested to clarified. Detailed comments on the proposed parameters were made by Nortel Networks and Vodafone AirTouch. This document was compared to the Vodafone AirTouch equivalent proposal for a few aspects, and was felt covering rather the same information. Additional frequency band granted in the future to UMTS was requested to be taken into consideration (forward compatibility). Enhancement measurement report requested the whole SI5 message to be received, otherwise ordinary report or fallback procedure should be identified, covering all possibilities. GPRS link was clarified.
Conclusion: Comments will be taken into account to update the CR, to be discussed on the reflector and presented at next SMG2-WPA meeting for approval.
Tdoc B10/00 “GSM to UMTS handover measurements” from Nokia, was presented by Mr. A. Nielsen. A number of open issues were tackled:
•	What is the expected accuracy of GSM - UMTS timing difference information?
•	What is the minimum number of samples required for one CPICH Ec/No value to report?
•	Should the MS be able to measure on more than one UMTS cell per idle frame?
•	What is reported when no UMTS measurements are performed?
•	How long time is the measurement results valid?
•	Test case that testes the measurement capabilities and not only the reaction time for new UMTS cells is needed!
A period of minimum 5 consecutive idle frames is required for identification of the strongest UMTS cell on a certain frequency. Some questions for clarification were raised from Mr. A. El-Saigh on the above points. Mr. J-F Minet commented that if a mobile station has not sent any report yet, handover should be forbidden, which was felt not in line with the present UMTS specifications by Mr. V. Hammer, i.e. a MS cannot reject an handover command). Blind handover, if supported, should also allow GSM-GSM blind handover (checking if timers run out of time...). Motorola volunteered to take care of the GSM-GSM case. Blind handover GSM-UMTS would need to be checked as well.
Tdoc B28/00 “Measurement result” and B17/00 “CR 04.18-A061 rev 2 Introduction of UMTS measurements in Measurement Results information element” were considered together. A few changes were suggested with reference to GSM 05.08. The document was felt as supplementary to Tdoc B09/00. Two possibilities for a solution were prospected, to be merged in one message.
Tdoc B36/00 “Measurement Order Connected Mode” and B16/00 “CR 04.18-A059 rev 2 Measurement command - Connected mode” were considered together. A threshold Qsearch (defining when to start UMTS measurements) and offset Moffset (to be used in comparing UMTS and GSM measurements) are proposed to be sent to the mobile. In case RSSI (mapped Ec/Io ) values shall be reported for UMTS neighbouring cell measurements the downloaded offset shall be used. The Qsearch parameter was contended (Siemens, Vodafone, FT); the Moffset was felt be different for different RATs. The SMG2 Chairman asked whether it should be supported (requirement) that the BSC re-use the existing handover algorithm, which was felt worth if no changes to BSC would be needed in such case. A formula (mapping function) to compare GSM and UMTS on the basis of a ”normalized” Quality scale was felt needed to encompass the need to rank cells (GSM and/or UMTS) the MS should be commanded to handover to. The idea was not agreed by Vodafone AirTouch, the reason being other criteria could be adopted as well. The way forward was found by adopting different specific parameters in connected mode and idle mode, respectively; UTRAN REPORTING parameter was felt to be called Multi RAT REPORTING parameter. Qualcomm reminded that a multi-carrier CR overlapped to the previous one.
Tdoc B12/00 “CR 04.18-A076 3G Measurement Command 1 - Connected Mode” and B13/00 “CR 04.18-A077 3G Measurement Command 2 - Connected Mode” from Vodafone AirTouch, were presented by Mr. C. Arzelier, that felt worth merging these CR with the previous one. Forward compatibility issue was brought up to support index type to indicate the center frequencies.
Tdoc B29/00 “New system info measurement order” from Ericsson, was presented by Mr. P. Edlund. A new System Information message type 5gamma is introduced in order to provide dual mode (UMTS/GSM) mobiles with information about UMTS neighbouring cells. The new coding for this new message is added in Information Elements SACCH Information and System Info Type.
Tdoc B14/00 “CR 04.18-A078 3G Measurement Order 1 - Idle Mode”and
Tdoc B15/00 “CR 04.18-A079 3G Measurement Order 2 - Idle Mode” from Vodafone AirTouch, were presented by Mr. C. Arzelier. This new measurement order is sent on the BCCH or extended BCCH to all mobiles in the cell, and only decoded by the MS supporting one or more non-GSM Radio Access Technology. Parameters differing in Idle and Connected Modes were asked to be called with differing names, depending on the corresponding CR to GSM 05.08.
Tdoc B21/00 “Adding UE Capabilities to Handover Request message”, Tdoc B22/00 “Adding UE Capabilities to Handover Required message”, Tdoc 23/00 “Adding UE Capabilities to RR Classmark Change” and Tdoc B39/00 “Transportation of Source to Target RNC in BSSMAP”, from Ericsson, were presented by Mr. P. Edlund. The proposed changes will add the UE capabilities for UTRAN to the Handover Request BSSMAP message. The changes will enable to transfer these capabilities from BSS to Core Network at invocation of the Handover from GSM to UMTS. Vodafone Airtouch and Qualcomm expressed some concern on the proposal in Tdoc B23/00. Alternative RATs were felt possibly covered in a Classmark 3 MSs. A new message was felt the best way to deal with the issue of adding UE capabilities. Cell identifier list would need to be modified as well in Tdoc B23/00.
Tdoc B3/00 “GSM-3G Handover: BSSAP aspects” from Nokia, was presented by Ms. K. Vainola.
Meaningfulness of the first two sentences in clause 3.1.5.1.2 was questioned by Nortel Networks; it was proposed to delete the two sentences. Cell Identifier List (preferred) should be able to identify the correct RNC.
Conclusion: a revised package of CRs to GSM 08.08 will be provided by next SMG2-WPA meeting.
Tdoc B37/00 “RR Intersystem Handover Command”, and Tdoc B25/00 “BSSMAP Handover Command for handover to UTRAN” from Ericsson, was presented by Mr. P. Edlund. “Presence” was suggested to become conditional (to save octects). Technologies should be aligned. References to be updated.
Conclusion: the revised package of CRs will be provided by next SMG2-WPA meeting.
Tdoc B18/00 “Procedure for a reduced TFCI signalling in GSM to UMTS HO cases”, from Siemens, was presented by Mr. D. Thomas. Ericsson felt the TFCI signalling not needed, as a pre-configuration would be pointed at (out of 16 possibilities, still subject to agreement), stored in the MS. Location update was felt a possible alternative.

Tdoc B19/00 “Target Id for Handover to UMTS” and B20/00 “Transport of target cell info in Handover signalling”, from Ericsson, were presented by Mr. P. Edlund. Nokia asked to wait discussing this contribution (and taking decision) until the output from an on-going meeting TSG-S2 will be illustrated. The Target Id is actually different in GSM (Cell Id) and UMTS (Target RNC and Cell Id within RNC), respectively. The concept of the “container” was accepted. The possible mechanism for building the whole target UMTS cell address was discussed whether a task for MSC and BSC, resolved by coding the Cell_Id proper format. This was felt a possible solution for UTRAN (different for other RATs). Conclusion: the decision at this meeting whether to put such “transparent” container in the MSC or in the BSC, was in favour of BSC. The discussion will be continued in the SMG2 reflector (Cc TSG-S2 and TSG-N1).
Tdoc B26/00 “Handover Command message for handover to UMTS” was provided for information.
Tdoc B27/00 “Pre-configuration of UTRAN RABs - Handover GSM to UMTS”, from Ericsson, was presented by Mr. P. Edlund. Acknowledged mode was felt needed. (Huge) required memory issue was brought up (3200 bytes). It is worth-noticing that the number of sets could depend on the MS capabilities. The framework for the download mechanism was requested to be provided.
Tdoc B38/00 “GSM - 3G Handover: Service based handover” from Vodafone AirTouch, was presented by Mr. C. Arzelier. This CR proposes the addition of a few bits to the Channel Type IE in order to communicate the desire (or otherwise) for intersystem handover. UTRAN-FDD; UTRAN-TDD and CDMA-2000 are all grouped under the same codepoint. Nortel Networks felt relevant the min/max channel desirable throughput. Editorial changes were suggested.
Tdocs 4, Tdoc 5->43, Tdoc 6->44, Tdoc 8
Tdoc B04/00 “Handover from GSM to cdma2000 MC-MAP” from Qualcomm Europe, was presented by Mr. F. Grilli. The document requested SMG2 that, when approving changes for GSM to UMTS handover, the GSM to cdma2000 MC handover is also considered as an option. Questions for clarifications were raised. The frame work was felt compatible with the previously discussed items related to this document.
Tdoc B43/00 “Changes to Measurement Order for Handover from GSM to cdma2000 MC-MAP”from Qualcomm Europe, was presented by Mr. F. Grilli. How the MS would communicate the requested information to GSM remains to be specified (after the confirmation that cdma2000 MS is supported for a certain frequency band). References (only published documents) to be updated, and the most recent version of the specifications will be used.

Tdoc B44/00 “Changes to Measurement Results for Handover from GSM to cdma2000 MC-MAP”, from Qualcomm Europe, was presented by Mr. F. Grilli. The modifications of the Measurement Results information element enable to report possible cdma2000 neighbours without introducing a new message. Qualcomm will produce the CRs in line with the decisions agreed for other RATs.

Tdoc B08/00 “Adding cdma2000 Capabilities to Classmark Change RR message”, from Qualcomm Europe, was presented by Mr. F. Grilli. This CR proposes to change the CLASSMARK CHANGE RR message for the handling of the cdma2000 Capabilities. These new capabilities cdma2000 can be handled similarly to MS Classmark 2 and 3 during the establishment of connection in GSM access mode. Comments. A separate message will be used, and care will be taken on the formats (bits 1-8 and 0-7). Qualcomm will produce (conditional) CRs in line with the decisions agreed for other related CRs.

Tdoc B33/00 “GSM to UMTS Handover security discussion paper”, from Ericsson, was presented by Mr. P. Edlund. It was suggested the document be forwarded to SMG10/TSG-S3 for review.

6	Handover and cell re-selection from GSM to 3G for packet switched connections
34,42
Tdoc B34/00 “GPRS cell re-selection CR 04.60 and some text in 04.18 to cover BCCH only cells”, from Ericsson, was presented by Mr. P. Edlund. In order to provide GPRS network with cell reselection to UMTS a measurement order is sent on PBCCH from the network to a UMTS capable multiband mobile to provide the mobile with information on neighbouring cells to be monitored within the cell. Packet System Information Type 3 message is updated containing pointers to UMTS Scrambling Code and UMTS Radio Frequency combinations. Comments: Other cell selection parameters should be taken into account in the revised version (e.g. BAR, PSI Type 3bis to be included, etc.).

Tdoc B42/00 “Proposed Liaison Statement on Handover from GPRS to UTRAN for R99”,
from Siemens, was presented by Mr. D. Thomas. TR 25.931 contains an example of handover from GPRS to UTRAN. SMG2 would like to clarify that for release 99, GPRS does not support handover (only cell reselection is supported) and would ask that this be noted in the text of TR 25.931. The LS was noted. The text will be posted on the TSG-R3 reflector.

7	“Reception” of mobile stations handed over to GSM from 3G
7.1	Circuit switched
Tdoc B07/00 “Handover from cdma2000 MC-MAP to GSM”, from Qualcomm, was mainly provided for information. Note that currently the [GSM Payload] carried by the MC-MAP Intersystem Handover Command Message is defined with a pointer to Section 9.1.15 of GSM 04.08. SMG2 indicated that a different reference should be included instead to GSM 04.18, and more appropriate information should be provided to indicate the correct frequency band. Check of field utility was requested. Cyphering and security level was felt not an issue and synchronisation was felt achievable in several ways (in practice).

7.2	Packet switched
No documents were treated under this Agenda Item.

8	Workplan

9	Any other business

Tdoc B41/00 “Proposed Liaison Statement to Clarify the Relationship between PLMNs and RATS” from Siemens, was presented by Mr. D. Thomas. It was clarified the list of PLMNs with an associated RAT only exist (i.e. no RAT selector list). The scanning mechanism was described. All clarifications requested from the document were answered by TSG-SA Chairman.

Tdoc B45/00 “Measurement performance for support of GSM to UMTS Handover”, from Ericsson, was presented by Mr. W. Muller. This document provided estimates of required number of Idle Frames for searching and measuring on UTRAN cells while camping on a GSM cell in in order to support Inter-RAT handover in connected mode. The document concluded it is possible to synchronize to one new UTRAN cell out of 10 within 10 Idle frames. The subsequent measurement may take one additional Idle frame. The active frames will typically not give enough time to allow for both the RAT mode change and synchronization for measurements i.e only Idle frames shall be assumed when developing requirements for the measurement performance.
Mr. A. El-Saigh commented that the switching time value chosen was a quite conservative figure, and argued about the synchronisation mechanism and measurements in practice.
The Chairman encouraged to progress the Handover work item in time for the next SMG2 meeting.

10	Closing of meeting
The Chairman thanked the Host (Ericsson) for the organisation of the meeting, and the delegates for their attendance. The meeting was closed.
