Providing packet-based multimedia services via a circuit bearer
First Claim
1. A method for providing a packet-based multimedia service to a mobile device in a network, wherein the service is defined by a telecommunications standard, and wherein the network does not support packet quality of service (QoS) functionality as required by the standard, the method comprising:
- establishing a packet signaling connection between the mobile device and network;
establishing a circuit bearer connection between the mobile device and network;
transferring signaling information for the multimedia service via the packet signaling connection in alignment with the standard; and
transferring data for the multimedia service via the circuit bearer connection in alignment with the standard, wherein the multimedia service is provided to the mobile device via the network as specified by the standard even though the network does not support the required QoS functionality.

Abstract
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.

8. A method for providing a packet-based multimedia service to an endpoint in a wireless network, wherein the service is defined by a telecommunications standard, and wherein the network does not support a packet quality of service (QoS) mechanism specified by the standard, the method comprising:
-
establishing a packet-based signaling context between the endpoint and a gateway;
establishing a circuit bearer leg between the endpoint and the gateway using the signaling context; and
controlling the transfer of data via the circuit bearer leg using the signaling context, wherein the signaling context is used to control the provision of the packet-based multimedia service via the circuit bearer leg in alignment with the standard. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A telecommunications system for providing a packet-based multimedia service to a mobile station (MS) in a wireless network, wherein the service is defined by a telecommunications standard, and wherein the network does not support a packet quality of service (QoS) mechanism specified by the standard, the system comprising:
-
a proxy call session control function (P-CSCF);
a media gateway connected to the P-CSCF; and
a plurality of instructions for executing within the network, the instructions for;
establishing a packet signaling context between the MS and the P-CSCF;
establishing a circuit bearer connection between the MS and the media gateway;
transferring signaling information for the multimedia service between the P-CSCF and the media gateway, and between the P-CSCF and the MS via the packet signaling connection in alignment with the standard; and
transferring data for the multimedia service between the media gateway and the MS via the circuit bearer connection in response to the signaling information. - View Dependent Claims (16, 17, 18, 19, 20)
