METHOD AND APPARATUS FOR HANDLING VOICE CALLS

摘要

The present invention relates to the communication technical field, and more particularly to a method and apparatus for handling voice calls. The embodiment of the present invention provides a method for handling voice calls, which comprises the following steps: when determining that the visited network to which the User Equipment (UE) belongs and the home network to which the UE belongs are not the same communication network, the Circuit Switched Fallback (CSFB) Proxy of the visited network to which the UE belongs sends a first initial address message to the Gateway Mobile Switching Center (GMSC) of the home network to which the UE belongs, so as to enable the GMSC to send a first router information acquisition request to the Home Location Register (HLR) of the home network to which the UE belongs. With the method provided in the embodiments of the invention, when the visited network to which the UE belongs and the home network to which the UE belongs are not on the same communication network, the CSFB Proxy can send the first router information acquisition request to the HLR through GMSC, thus ensuring the normal continuation of a voice call.
