Abstract

The invention provides a calling request redirection method and device, and a calling request continuing method and device. The calling request redirection method comprises steps that home location query equipment of a called subscriber receives a first position query request sent by a mobile switching centre simulation MSCe of a calling subscriber; the home location query equipment determines the called subscriber is a VoLTE user or not; if the called subscriber is determined as the VoLTE user, the home location query equipment sends a first position query response to the MSCe of the calling subscriber, wherein the first position query response carries routing information of an IMS network and is used for indicating the MSCe of the calling subscriber to redirect the calling request to the IMS network via the routing information. The problem that the efficiency of paging the called subscriber when the CDMA network and the IMS network coexist is low is solved, and the efficiency of paging the called subscriber is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a call request redirection method, a call request connection method and a device thereof. Background technique [0002] Code Division Multiple Access (CDMA for short) technology is an important technical standard in the third generation mobile communication system. At present, CDMA commercial networks have been established in North America, China and some countries in Asia. [0003] Evolving to the fourth generation wireless data network (namely LTE / EPC) is a general trend for operators. According to statistics, more than 100 operators around the world have launched LTE commercial services. In the LTE / EPC network evolution, both 3GPP and GSMA clearly adopt IMS network to provide users with LTE-based voice service (Voice over LTE, referred to as VoLTE) services, and the US Verizon, Japan KDDI, Hong Kong PCCW, etc. have announced VoLTE was officially commercialized in 2014. ...
