Method and apparatus for transmitting SRVCC capability information, and system

摘要

Embodiments of the present invention relate to the field of communications technology. A method and apparatus and system for transmitting single wireless voice call continuity (SRVCC) capability information, which can solve the problem of voice call continuity after the terminal has been switched to a high standard network by intersystem handover, is disclosed. The method in an embodiment of the present invention comprises the steps of: obtaining, by a network element of a core network (CN), SRVCC capability information of a terminal from the terminal, wherein the terminal, from the first standard network by inter-system handover, Access to a second standard network in which a network element of a CN is located, wherein the first standard network does not support the SRVCC function, and the second standard network supports the SRVCC function; And sending, by the network element of the CN, the SRVCC capability information to a network element of a radio access network (RAN).
