Abstract
Methods for handling PS and CS voice services between a mobile communication device and a service network are provided. The method includes providing, by the service network, a first type of communication service to the mobile communication device and concurrently receiving, by the service network, a service request message to request for establishment of a second type of communication service, determining, by the service network, whether any type of communication service is an emergency service, and declining, by the service network, the type of communication service that is not the emergency service, wherein the service network only supports one type of communication service to the mobile communication device at one time.
Claims13
A handover method, handing over a circuit-switched (CS) voice service and a packet switched voice (PS) voice service of a mobile communication device by a service network from a source cellular station to a target cellular station, comprising:
- determining, by the service network, to perform a handover procedure of the CS voice service and the PS voice service from the source cellular station to the target cellular station based on a handover measurement of a radio connection between the source cellular station and the mobile communication device;
- and
- terminating, by the service network, at least one of the CS voice service and the PS voice service when the handover procedure is determined to be performed and the target cellular station only supports one CS voice service.
A method, handing over a circuit-switched (CS) voice service and a packet switched (PS) voice service of a mobile communication device in a service network from a source cellular station to a target cellular station, comprising:
- receiving, by the mobile communication device, a release message from the source cellular station upon determination that a handover procedure of the CS voice service and the PS voice service from the source cellular station to the target cellular station based on a handover measurement of a radio connection between the source cellular station and the mobile communication device is to be performed;
- and
- in response to the release message, releasing, by the mobile communication device, an established resource for the CS voice service and the PS voice service.
A method, establishing a communication service between a mobile communication device and a service network, comprising
- providing, by the service network, a first type of communication service to the mobile communication device and concurrently receiving, by the service network, a service request message to request for establishment of a second type of communication service;
- determining, by the service network, whether any type of communication service is an emergency service;
- declining, by the service network, the type of communication service that is not the emergency service;
- and
- wherein the service network only supports one type of communication service to the mobile communication device at one time.
A method, establishing a communication service between a mobile communication device and a service network, comprising
- receiving, by the mobile communication device, a first type of communication service and concurrently receiving, by the mobile communication device, a request for establishment of a second type of communication service;
- determining, by the mobile communication device, whether any type of communication service is an emergency service;
- declining, by the mobile communication device, the type of communication service that is not the emergency service;
- and
- wherein the mobile communication device only supports one type of communication service at one time.
A method, establishing a communication service between a mobile communication device and a service network, comprising
- receiving, by the mobile communication device, a first type of communication service and concurrently receiving, by the mobile communication device, a request for establishment of a second type of communication service;
- suspending, by the mobile communication device, the first type of communication service that is not an emergency service;
- receiving, by the mobile device, the second type of communication service;
- and
- wherein the mobile communication device only supports one type of
