Embodiment Construction

[0032] Embodiments of the present invention provide a new functionality in IP Multimedia Subsystem (IMS) networks called Messaging Resource Function (MsgRF). The MsgRF may be referred to as a "node" in the IMS, although it may be implemented as a standalone node, co-located with other functions in a node, and / or implemented in a cloud configuration. This function implements a Session Initiation Protocol (SIP) interface that allows an IMS Application Server (AS) to manage messaging in a session or group via a SIP-based control protocol (eg using SIP INFO). This is similar to how MSCML / MSML is used for media resource functions, which rely on session negotiation (also known as "establishing a session") using Session Description Protocol (SDP) via 3pcc (Third Party Call Control), sending chat messages, Receive chat messages (like "ivr" used by MRF for audio / video), manage group conversations (like "conf" used by MRF to manage conferences).

Abstract

A method of exchanging content between a User Equipment, UE, and an Application Server, AS, of an IP Multimedia Subsystem, IMS, or between the UE and a peer UE. The method comprises establishing a Session Initiation Protocol, SIP, session between said messaging resource function and the AS; establishing a Message Session Relay Protocol, MSRP, session between the UE and a messaging resource function of the IMS; and exchanging content between the first mentioned UE and the messaging resource function in messages sent over the established MSRP session.

Description

technical field [0001] The invention relates to a method and an arrangement for exchanging content between an Application Server AS and a User Equipment (UE) of an IP Multimedia Subsystem IMS. It takes advantage of a new networking capability called Messaging ResourceFunction here. Background technique [0002] IP multimedia services provide a dynamic combination of voice, video, messaging, data, etc. within the same session. By increasing the number of possible combinations of media and basic applications, the number of services offered to end users will increase and the inter-personal communication experience will be enriched. This will lead to a new generation of personalized rich multimedia communication services. [0003] The IP Multimedia Subsystem (IMS) is a technology defined by the 3rd Generation Partnership Project (3GPP) for providing IP multimedia services over mobile communication networks. IMS provides key features for enriching the end-user person-to-person...
