摘要： A method and apparatus for establishing a Voice over LTE (Long Term Evolution) (VoLTE) call in a communication network are provided. After a request for establishing a VoLTE call is received, a user equipment (UE) involved in the VoLTE call that is in LTE coverage can be identified. One or more dummy messages are send to the identified UE after the VoLTE call enters into ringing phase. An interval between successive dummy messages is shorter than a first time period set for determining whether to release radio resource for supporting the VoLTE call in LTE coverage. Sending the dummy message can be stopped if the VoLTE call is answered or is cancelled. As a consequence, time spending on establishing a VoLTE call is shortened and good performance characteristics is achieved, and signallings on networks are reduced.

摘要： Embodiments of the present disclosure provide methods, apparatus and computer program product for facilitating location based services and/or location based policy control. A method at a first network node comprises receiving a message from a terminal connected to the first network node via non-3GPP access, the message including a local IP address or both the local IP address and a port number of the terminal; and sending geographical location related information of the terminal to an IMS network via at least a network node for policy control function of the IMS network. Methods at other network nodes and corresponding apparatus are also provided. With the embodiments, location based services and/or policy control may be provided to non-3GPP access devices.
