The current charging specifications cover online charging from SMS Routers and IP-SM-GW but only offline charging from SMS-SC. Adding online charging from SMS-SC brings the following advantages for:

1. operators and charging system vendors: a consistent interface specification for online charging across SMS Routers, IP-SM-GW and SMS-SC;

2. operators: reduced cost for SMS online charging adaptations when they decide to follow a multi SMS-SC vendor and/or router policy for example. (Currently more than 6 flavours of vendor-specific extensions to Diameter specifications are in use for online charging of SMS.)

3. SMS-SC and charging system vendors: less protocols to implement and maintain for online charging of SMS.

Within the IMS, the Multimedia Resource Function (MRF), through interactions with the User Equipment (UE), Application Server (AS) and Serving Call Session Control Function (S-CSCF), provides e.g. video and audio conference capabilities, and the support of announcements, tones and media streams processing.

MRF is decomposed into two functional entities, i.e. the MRFC and MRFP. The Mp interface between these two functional entities supports the H.248 protocol with the additional support of Multimedia specific H.248 Packages.

This work adds further functionality to the Rel-7 basic function by enhancing the Mp procedures and H.248 Profile.

• The MRFC:

• Controls the media stream resources in the MRFP

• Interprets information coming from an AS and S-CSCF (e.g. session identifier) and control MRFP accordingly

• Generates CDRs

• The MRFP:

• Controls bearers on the Mb reference point

• Provides resources to be controlled by the MRFC

• Mixes incoming media streams (e.g. for multiple parties)

• Sources media streams (for multimedia announcements)

• Processes media streams (e.g. media analysis)

Rel-7 Mp interface work implements the basic requirements for the Mp interface applications, including playing tone/announcement, detecting DTMF, ad-hoc audio and video conference, etc.

However, Floor control of conference was moved by TSG CT from Rel-7 to Rel-8. Additionally, although requirements such as Message conference were specified in TS 24.147, TS 24.247 and TS 23.228, the corresponding Mp solutions have not been defined yet. This work includes these missing functionalities to the Mp interface.

To further develop and enhance the use of H.248 protocol between the MRFC and MRFP, the requirements, procedures and H.248 Packages were identified and specified. New H.248 Packages were defined by ITU-T SG 16 and/or CT4. The result produced by external bodies was evaluated taking into account the applicability for the packages.

This work provides solutions to the following requirements:

• Floor Control requirement of conference service

• Message conference

• Number of Participants in conference
