    摘要: Apparatus and methods of establishing an emergency voice call include user equipment transmitting, and a first serving core network receiving, a request for an emergency call via a wireless access network. The apparatus and methods further include a determination by the first serving core network of an alternative serving core network. In some aspects, the determination may be made based on a user equipment location from a location retrieval function, which may obtain such information from other network components or from the user equipment. In other aspects, the determination may be based on lack of capability or lack of capacity. Further, the apparatus and methods also include establishment of the emergency call with a second serving core network different from the serving core network based on the determination.

    摘要: A mobile station that is configured to facilitate coordination of supplementary services in a centralized fashion may include circuit-switched (CS) domain components that are configured to place voice telephone calls in a CS domain. The mobile station may also include IP multimedia subsystem (IMS) components that are configured to place voice telephone calls in an IMS domain. The IMS components may include a transport component for facilitating communication with an IMS core network. The IMS components may also include a signaling component that is configured to exchange information with a centralized server on the IMS core network via the transport component. At least some of the information that is exchanged with the centralized server may be related to supplementary services for the voice telephone calls in the CS domain as well as the voice telephone calls in the IMS domain.

    摘要: Fall back using mobile device assisted terminating access domain selection is provided. A network entity forwards an invitation to a session to a mobile device. Session has packet switched bearers for media. Mobile device replies with a rejection of the invitation and a request for network entity to hold the session. Rejection is based on mobile device determining circuit switched bearers should be utilized. Mobile device sends a circuit switched call and network entity correlates the circuit switched call with the session. A dialog is set up over circuit switched domain bearers and Internet Protocol Multimedia Subsystem bearers.
