MOBILE COMMUNICATIONS METHOD AND SYSTEM FOR SIGNALLING INFORMATION RELATING TO NETWORK'S CAPABILITIES

摘要

Methods and apparatuses are provided for transmitting information from a serving network element to a mobile terminal in a mobile communications network. The serving network element transmits indication indicating whether a voice over internet protocol (VoIP) via packet switched (PS) session is supported, to the mobile terminal, via an eNode B, during one of a tracking area updating (TAU) procedure and an attach procedure. A Voice Call Continuity (VCC) capability of the mobile terminal is received from the mobile terminal. It is determined whether or not to anchor a call based on the received VCC capability of the mobile terminal. The indication is determined based on a capability of the serving network element.
