A method of reserving credit for a mobile subscriber in respect of an IP multimedia service. The method comprises, following initial registration of the subscriber to the IP Multimedia service but prior to invocation of an IP Multimedia service, using the early session establishment procedure to reserve a credit amount at a charging control node and to notify an IP Multimedia Serving Element of the credit reservation, whereupon, at invocation of said IP multimedia service, the IP Multimedia Serving Element is able to proceed immediately with the session establishment.

Charging mechanisms for IP multimedia services

A method of transporting image or video information between end user terminals via a packet switched network whilst a circuit switched connection is established between the end users includes establishing a circuit switched connection between a plurality of end user terminals for carrying voice traffic. The method also includes using the. Message Session Relay Protocol (MSRP) to encapsulate image or video information transmitted between end user terminals via a packet switched network, where MSRP related traffic is routed between said end user terminals via one or more MSRP enabled nodes. Additionally, the method includes installing service policies into the or at least one MSRP node from a session initiation protocol (SIP) application server (AS) located in the control-plane of an IMS network and checking multimedia service requests against the installed policies to control end user terminal access to certain packet based services.

Exchange protocol for combinational multimedia services

Method, devices and computer programs for routing a message to a first network server (MSC) in a server pool (CNSP) of a mobile communication system are disclosed. The mobile communication system comprises a controller (BSC) of an access network (AN) connectable to the first network server (MSC) and at least one further network server (MSC) in the server pool (CNSP), wherein service points are defined (S) and one or more of the service points are allocated (S) uniquely to each of the network servers (MSCMSC) in the server pool (CNSP). At least one of the network servers (MSCMSC) has allocated (S) at least two of the service points. A temporary identity is assigned (S) by the first network server (MSC) to a mobile device (MS). The temporary identity includes a selected service point which is selected (S) from the one or more service points allocated to the first network server (MSC). The temporary identity is transmitted (S) to the mobile device (MS) and a message (S) from the mobile device (MS) to the first network server (MSC) is routed (S) to the first network server (MSC) by extracting the selected service point from the temporary identity received by the mobile device (MS) and applying a routing algorithm to the selected service point. The routing algorithm reveals the first network server (MSC) from an analysis of the selected service point.
