A synch server comprises a first interface configured to transmit and receive MAP messages, and communicate with a Home Location Register (HLR) in a Circuit-Switched (CS) network, a second interface configured to communicate with a Home Subscriber Server (HSS) in an IP-Multimedia Subsystem (IMS) network, and a third interface configured to transmit and receive Extensible Markup Language (XML) Configuration Access Protocol (XCAP) messages. A synch function module is configured to receive a message containing a change to a supplementary service setting associated with a User Equipment (UE) connected to a Circuit-Switched (CS) network or an IMS network, and communicate the change to the supplementary service setting to both the HLR and the HSS so that the supplementary service settings in both the HLR and the HSS are updated to reflect the change to the supplementary service setting.

System and method for supplementary services setting synchronization

A packet-based multimedia service is provided to a terminal in a network. A packet signaling connection is established between the terminal and the network. Signaling information for the multimedia service is transferred via the packet signaling connection using Session Initiation Protocol (SIP) or a similar protocol. A circuit bearer connection is also established with the terminal. Data for the multimedia service is transferred via the circuit bearer connection. This allows the data to be carried across networks which do not support the required QoS functionality for the packet-based service, or which cannot efficiently carry packet-based data. The circuit bearer connection can be established by a network entity or by the terminal. The circuit bearer can be interworked to a packet-switched bearer at some point in the network, such as at a gateway, so as to provide a remote party with the appearance that a fully packet-switched connection is being used.

Providing packet-based multimedia services via a circuit bearer

Providing packet-based multimedia services via a circuit breaker

Provided is a method and system for providing a packet-based multimedia service to a mobile device in a network. The service is defined by a telecommunications standard, such as the 3GPP IP multimedia subsystem (IMS) standard, and the network does not support packet quality of service (QoS) functionality as required by the standard. A communications session embodying the method may be initiated by the mobile device or by the network. The method begins by establishing simultaneous packet signaling and circuit bearer connections with the mobile device. Signaling information for the multimedia service may then be transferred via the packet signaling connection using a session initiation protocol (SIP) or similar protocol. Data for the multimedia service may be transferred via the circuit bearer connection. This enables a feature rich signaling protocol to be used to provide the multimedia service via the network in alignment with the standard, even though the network does not support the required QoS functionality.
