___________________________________________________________________________

1	Introduction
This is the report on the second meeting of SWG5, held at the TSG T2#3-meeting in Shin Yokohama. The first meeting, that was supposed to have been taken place at TSG T2#2 in London, was cancelled due to too few delegates showing up. For this meeting, 7 delegates from 6 different companies showed up which was considered enough to have some work done.

The list of participants can be found in section 4.

The list of input documents can be found in section 5 and the list of output documents in section 6.
2	Input documents
The following input documents were reviewed and discussed.
2.1	T2-99381 TR ‘Multi-mode issues’
Source: Telia AB
This document presents a first drafted version of the report on Multi-mode issues and it was presented by Telia. 

While reviewing the draft report the scope had to be addressed several times. This often in due to issues not directly in referred to the terminal. The scope is:
“The purpose of this 3GPP Technical Report is to describe work done on multi-mode related issues and to identify areas that need additional treatment to facilitate efficient multi-mode usage. The report outlines definitions specifically important for usage of multi-mode terminals and scenarios describing the concept. The report refers, as far as possible, to existing specifications/reports or to specifications/reports being produced in 3GPP or within other relevant foras.”

As stated in the scope, scenarios will be defined to find the expected performance of the multi-mode terminal in all possible situations. Outgoing from the scenarios, the work already done will be analysed.
Some important situations and issues to cover in the scenarios were outlined. The situations are:
•	At start up
•	At an incoming connection (when the terminal is in either idle or active/dedicated mode)
•	At an outgoing connection (when the terminal is in either idle or active/dedicated mode)
•	For mobility management (when the terminal is in either idle or active/dedicated mode)
•	Roaming
•	Loose of coverage

These scenarios will be of main concern for the group between the next meetings and they will be discussed through the e-mail list.

2.2	T2-99370 Table of documents including multi-mode issues
Source: Telia AB
This document contains the list of documents identified so far as relevant for the work in this SWG and was presented by Telia. It is a first attempt to collect all documents with work already done on multi-mode terminals and will be used as a reference document when producing the report. The list was just briefly gone through and the main sections where multi-mode issues are addressed were pointed out, as stated in the table.

The documents mentioned in T2-99370 can be found in T2-99371– T2-99380, T2-99386 and T2-99387.

In due to the work of collecting all documents relevant for work already done on multi-mode issues, an LS (T2-99394) was produced to be sent to all WG:s within 3GPP. This LS informs the WG:s of the ongoing work in SWG5 and asks them to provide the group with information about reports/specifications existing or being under creation, that contains issues related to multi-mode terminals.

2.3	T2-99391 Proposed revision of WI:s on Multi-mode terminals
Source: Telia AB
The presentation of this document was made by Telia and it suggests that the two WI created for SWG5 should be merged into one and in due to that is also suggests a new timetable for this work item. This was agreed in the group, after a discussion on the timetable, and the new title for the WI will be “Multi-mode issues” and the timetable will be:
First draft			31/05/1999
First completed draft		17/09/1999
WG approval			04/10/1999
TB approval			07/10/1999
Publication			29/10/1999

A new document with the agreed timetable can be found in T2-99392.

3	Future work
The next meeting will take place at the TSG-T2#4 meeting in Miami, 14th-16th of June. At this meeting it will be considered if the SWG will have an additional meeting in between that meeting and TSG-T2#5.

In between the meetings, work will progressed using the e-mail list on the 3GPP-server.

4	Participants list
There were 7 participants from 6 companies in the group, the NEC-representative only present the second day when the Samsung delegates were missing.
