The present invention relates to the field of mobile communications technologies, and in particular, to an information transmission method, an information modification method, and apparatuses, so as to solve a technical problem of voice transmission interruption in an SRVCC scenario in the prior art. In embodiments of the present invention, when a UE is in a connected state, a base station is notified of an SRVCC capability of the UE in real time, so that the base station can update the locally stored SRVCC capability of the UE in real time, and then determine, according to an actual situation, whether to initiate an SRVCC process, thereby ensuring a success rate of the SRVCC process and avoiding a possible phenomenon of call drop as far as possible. |
