4 Broadcast/Multicast BCMCS Requirements Revision A (S.R0030-A) Revision A of Stage 1 was published January 2004 BCMCS physical layer specification work is completed in TSG-C BCMCS is in advanced stages of development in TSG-X BCMCS Security Framework (S.R0083-A) This security document was published in October 2003 Fundamental concept of BCMCS security is a subscription model providing a basis for managing authorship rights (e.g. revenue sharing with digital rights holder); This may be combined by additional DRM considerations for the content being broadcasted/multicasted

5 Immediate Messaging and Presence IM and Presence Requirements Revision 0 of Stage 1 Immediate Messaging (S.R0061-0) and Presence (S.R0062-0) were published October 2002 They are based on –RFC 2778 “A Model of Presence and Instant Messaging” and –RFC 2779 “Instant Message/Presence Requirements” IM/Presence Stage 1s should be highly aligned with the equivalent projects in 3GPP, which are also based on the two stated RFCs Discussion IM is one of many potential applications of Presence capability Another prominent one is PoC Close coordination on Presence capability will ease interoperability of many such applications Coordination with IETF will ease interoperability with the like non-wireless services

6 MMS (1/3) MMS Requirements Revision 0 (S.R0064-0) Revision 0 of Stage 1 published October 2002 Conceptually similar with 3GPP equivalent Permits additional protocols for the client-server interface (MM1) – several are defined in MMS specifications –X.S MM1 Using OMA/WAP-defined protocol (published April 2003) –X.S MM1 Using M-IMAP for Message Submission and retrieval (published May 2003) –SIP-based MM1 yet to be published

7 MMS (2/3) MMS Requirements Revision A (S.R0064-A) Currently under development Modifications include –Incorporation of DRM Issues (refers to OMA DRM v1_0) –Supplemental VASP related requirements (note that MM7 specification, defining interface to a VASP is published April 2004 in X.S ) –Short Code addressing option –Suppression of message forwarding loops –Support of Hyperlinks imbedded in message payload (e.g., plain text, HTML, etc.) –Network based message repository option These modifications should keep it in closer alignment with the 3GPP version

8 MMS (3/3) Collaboration with OMA The need for MMS interoperability between various networks (including landline ISPs and corporate intranets) and technologies (CDMA, GSM, WLAN, …) is critical for the uptake of MMS It would be best if the bulk of specifications that are technology neutral are developed in a single place There are very few access dependent aspects (e.g. some multimedia source coding formats) 3GPP2 is in principle in favor of relying on OMA for maintenance and further development of MMS 3GPP2 has approved submittal its work to OMA for such purpose, pending resolution of IPR alignment issue.

9 Location (1/3) Background Geo-location is a very important capability for many applications in mobile wireless systems 3GPP2 has devoted considerable effort toward development of underlying technology and location based services, a process that is ongoing Published specs: Spec.Subject/TitleStatus C.S0022-0Position Determination ServicePublished 4/01 N.S0030-0Enhanced Wireless 911 Phase 2Published 4/02 X.S0002-0Location Services Using Enhanced 911Published 2/04 S.R0066-0IP Based Location Service RequirementsPublished 4/03

10 Location (2/3) Circuit-Switched Location N.S0030 specifications are complete as of April 2002 Transmission of mobile station location in case of emergency distress, known in the US as E-911 –Circuit-switched call to emergency center –Location (LAT, LON) is conveyed via ANS-41 SS7 messages X.S0002 specifications are complete as of February 2004 for transmitting mobile station location for commercial (non- emergency) applications –Can use many common infrastructure elements as in N.S0030 –Contains controls for privacy (e.g. mobile subscriber can block access if location privacy is desired)

11 Location (3/3) IP Based Location Requirements document S.R published as of April 2003 Based largely on the circuit-switched counterpart in X.S0002 –Same general requirements, but accessible via IP-based interface –Allows reuse of large portions of existing location infrastructure for rapid deployment of services IP Based Location Requirements Revision A (S.R0066-A) Development started in 2003 Not much progress due to desire to first develop specifications and deploy Revision 0 Some newly proposed requirements are still subject to decisions of 3GPP2: –Codeword based security –Diluted precision as way of controlling privacy –Various forms of location reporting triggers (e.g. periodic, distance segment traveled, velocity threshold, etc.)

12 PoC PoC System Requirements Document Revision 0 (S.R0100-0) “System Requirements” is conceptually similar to Stage 1, but there is a difference in emphasis –Stage 1 emphasis is user perception –System Requirement emphasis is development of network capability, based on which service can be defined Currently in early stages of development The intent is to work in concert with OMA PoC requirements and beyond PoC requires close coordination because of high dependence on underlying and radio access and network capabilities

13 NFCC (1/2) Network Firewall Configuration and Control Stage 1 (S.R0103-0) Draft requirements document under development NFCC is related to Content Screening - currently BoF status in OMA, which may be addressing at the application layer some of the same problems that NFCC is addressing at the network layer Background In IP-based wireless networks, mobile devices have always-on Internet connectivity, making them vulnerable to direct attacks at the network protocol layer via unsolicited IP packets Network firewalls provide protection from penetration of unsolicited IP traffic to corporate intranets, while ISP subscribers typically use commercial firewalls on their devices for similar purpose Firewalls can also be used in wireless networks to provide protection against unsolicited IP packets

14 NFCC (2/2) Overview of NFCC requirements (under review) Protection is based on subscription identity (e.g. IMSI, NAI), not IP address Degree of firewall protection settable per subscriber, e.g. –Allow all IP packet through (no protection) –Allow IP traffic only from a predefined list of IP addresses/ports –Allow initial unsolicited packet from a source, but block future packets if no reply to the solicitation Configuration: Operator can set default firewall parameters for each subscriber, users can augment their own firewall parameters from their mobile devices via IP-based signaling Applicability: Simple IP and Mobile IP; IPv4 and IPv6 Scalability: NFCC solution should scale well with the number of IP flows being processed

15 Conclusions Several 3GPP2 and OMA projects may be of mutual interest Further exchange should take place between two organizations to coordinate requirements development and alignment, if necessary web site is openly accessible with wealth of information Published Requirements (Stage 1) documents are in S-series of documents (published by TSG-S) All meeting Contributions are placed on the web site after every meeting Contribution S , where is meeting date (e.g contains a table with latest status of TSG-S documents under development
