Abstract: A method is provided for indicating an IMS (Internet Protocol Multimedia Subsystem) emergency call back to a user equipment and an access network. The method comprises including in a message from a PSAP (Public Safety Answering Point) to the user equipment and the access network an indication that the emergency call back is from the PSAP.

Abstract: A mobile device configured for communication in both packet and circuit switched domains. The mobile device includes a domain selector. The domain selector is configured, responsive to selection by a user of one of the packet switched and circuit switched domains, to promote mobile device communication via the selected one of the packet switched and circuit switched domains.

Abstract: A mobile device, method, and machine instructions for mobile device communication are provided. The mobile device includes a voice call continuity status checker to determine a voice call continuity status and use the voice call continuity status to determine whether to initiate voice call continuity related activities. The method includes determining a voice call continuity status and using the voice call continuity status to determine whether to initiate voice call continuity related activities. When executed, the machine instructions perform a method that includes determining a voice call continuity status and using the voice call continuity status for voice call continuity related activities.

Abstract: A system to promote communication in a second domain responsive to a failure in a first domain. The system includes a first domain for communicating, and a second domain for communicating. The system includes a rejection message and a mobile device. The rejection message transmitted upon a failure of a call in the first domain. The mobile device configured to communicate in both the first domain and the second domain. The mobile device configured to attempt the call in the second domain responsive to receiving the rejection message in the first domain.

Abstract: Apparatus, and an associated method, for allocating resources at a target cell, or cells, of a cellular communication system. Determinations are made of the positioning and of the velocity, of a mobile station. Predictions of a target cell and when a handover is likely to be requested are made. Responsive thereto, a request is made prior to a handover request for the allocation of resources to permit the continued effectuation of a communication service upon handover of communications to the target cell.

Abstract: Apparatus, and an associated method, facilitates service degradation in a radio communication system, such as a cellular communication system. A service degradation profile is created, associated with a particular communication service-type, and includes values of QoS (quality of service) level values. If communication at levels corresponding to the values of the desired QoS level parameters is unavailable, efforts are made to effectuate, or maintain communication at quality levels corresponding to values of at least first QoS level parameters values. Service degradation thereby occurs pursuant to a selected profile, reducing the need for service renegotiations and reducing the possibility that an abrupt termination of a communication session might occur.

Abstract: Apparatus, and an associated method, for maintaining a selected QoS (quality of service) level of communications by a mobile station as the mobile station travels throughout an area encompassed by a radio communication system. Subscriber QoS classes are defined. One of the QoS classes is selected pursuant to a service subscription permitting the mobile station to communicate in the radio communication system. The selected QoS class is stored at a service subscription register. During communications with the mobile station, resources are reserved for use by the mobile station at a level corresponding to the selected QoS class.
