  • Multiplexing media components of different sessions
    Patent number: 8462798
    Abstract: An apparatus and a method are provided for multiplexing different sessions using the same authorized contexts for media. The method includes distinguishing different control plane sessions by a user equipment, and identifying media flows of a same application among the different control plane sessions by the user equipment by setting a service identifier. The method further includes sending the service identifier by the user equipment to a call state control function including a policy decision function, and authorizing quality of service for a user plane context by the policy decision function. Furthermore, the method includes enabling, by the policy decision function based on the service identifier, the different control plane sessions with media flows of the same application to share the same user plane context with the authorized quality of service to multiplex the different control plane sessions with media flows of the same application.

  • Multiplexing media components of different sessions
    Patent number: 7522613
    Abstract: A method of multiplexing different sessions using the same authorized contexts for media, comprising: distinguishing the sessions to be multiplexed, by a device; creating a new session on a control plane; indicating media flows of different sessions; and enabling the sessions to share the same authorized context for media, thus being multiplexed.

  • Access flow based charging for IMS/POC services
    Publication number: 20050026558
    Abstract: A method and system of flow based charging for IP multimedia system services are disclosed. The system includes a call processing server, and a session charging functionality. The method comprises negotiating media to be used within a session during a session initiating signaling. The method also includes generating a set of charging flow identifiers according to a predefined mechanism. The set of charging flow identifiers are associated with respective charging identifiers of the IP multimedia system identifying the session. A charging identifier of the IP multimedia system and a charging flow identifier globally uniquely identify a media component within a session. The call processing server and the session charging functionality generate the same charging flow identifiers by using the predefined mechanism so that the charging flow identifiers are known before any resource reservation occurs.
