Title:	Proposed Modification on ADN Description in 21.11
___________________________________________________________________________

Abstract
This contribution proposes new features related to ADN based on our requirements, and also shows modified images of ADN description in 21.11.

1.	Introductiond
At the previous meeting, 'enhancement of ADN files' was incorporated in our working procedure with highest priority.

2.	Discussion
As an comparison result between phone book function supported by normal PDC MS and ADN function in GSM SIM(11.11), following features are identified. These features should be incorporated into requirements for USIM. 

Features which have normally been supported by PDC MS's phone book functionality but seems not to be supported in 11.11 are;

-	Two names per record,
-	User definable groupings,
-	500 records and
-	Secret record(s)

Features which have been supported by advanced PDC MSs are:

-	Multiple phone numbers per record,
-	E-mail address field and

Addition to that, features may be supported by near-future PDC MS are;

-	Synchronisation between the ADNs in USIM and external phone book in e.g. personal organizer.

2.1.	Two names per record
The necessity of this field is owing to the style of Japanese language. Japanese language has two major ways of expression i.e. by phonogram like 'Hiragana' or 'Katakana' alphabet, or by ideogram like Chinese characters. Actually, PDC MS indicates names by using Chinese characters, however, ADN records are sorted, indexed and looked up by Japanese alphabet (Hiragana or Katakana). Therefore, ADN should be extended to support two name per record, for instance one is for indication and the other is for sorting, indexing and looking up.
This feature may be achieved based on the mechanisms proposed in TdocTSGT3#1(99)018.

2.2.	User definable groupings
Each ADN records may be grouped into finite set of groups which are defined by user (e.g. business, private, etc). Specific group index for this feature should be defined. 

2.3.	500 records
Considering the capacity of recent PDC MS, maximum record number should be extended up to around 500.

2.4.	Secret records
In order to make use of Auto-ON function, some users may usually disable CHV1. Even if so, he/she may want to keep some ADN records in secret. Hence, some ADN records should be able to remain in secret even if CHV1 is disabled. Those records are become visible by inputting e.g. specific secret code (other than CHV1) by user.

2.5.	Multiple phone numbers per record
It should be possible to have multiple phone numbers (e.g. office, home, fax, mobile or pager) per record. Addition to that,  information for identifying those attributes are also needed. 

2.6.	E-mail address
In order to send email from UE/USIM via SMS, email address should be able to be stored in conjunction with ADN records.

2.7.	Synchronization between the ADNs in USIM and external phone book in e.g.personal organizer 
It should be possible for user to synchronize between ADN data in USIM and external phone book in e.g. personal organizer. For this purpose, specific identity to maintain the linkage between two entities may be needed.

3.	Proposal
The features discussed above should be incorporated into the requirements of USIM. Following square shows proposed modification of 21.11 section 9.2 ADN.

9.2	ADN
From the user’s perspective, the ADN feature is one of the most important visible functionality delivered by the card. The GSM ADN should be enhanced e.g. by being able to group users, in order to separate between business and private numbers, or by assigning a class identifier to users in order to associate them with a particular mode of alerting. Another possible extension to the ADN functionality could be the ability to have a second name field (i.e. two names for one number). Required enhancements are described in subclauses below.
For all these enhancements, additional information needs to be stored , e.g. by appending it to the existing data structure of the records of the GSM ADN file, or by adding additional files which carry the necessary information and are linked to the ADNs.

9.2.1	Support of two names per record

In order to adapt to the style of some languages(e.g. Japanese), ADN should be extended to support two names per record, for instance one is expressed by ideogram for indication and the other is expressed by phonogram for sorting, indexing and looking up.

9.2.2	Support of User definable groupings

Each ADN records should be able to be grouped into finite set of groups which are defined by user (e.g. business, private, etc).

9.2.3	Extension of maximum record number

Maximum record number should be extended up to around 500.

9.2.4	Support of secret record

Depend on user's demand for privacy, some ADN records should be able to remain in secret even if CHV1 is disabled. Those records are become visible by inputting e.g. specific secret code (other than CHV1) by user.

9.2.5	Support of Multiple phone numbers per record

It should be possible to have multiple phone numbers (e.g. office, home, fax, mobile or pager) per record. Addition to that,  information for identifying those attributes are also needed. 

9.2.6	Support of email address

In order to send email from UE/USIM via SMS, email address should be able to be stored in conjunction with ADN records.

9.2.7	Synchronization between the ADN data in USIM and external phone book in e.g.personal organizer

It should be possible for user to synchronize between ADN data in USIM and external phone book in e.g. personal organizer. For this purpose, specific identity to maintain the linkage between two entities may be needed.
