Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. The following description of at least one exemplary embodiment is merely illustrative in nature and in no way taken as limiting the invention, its application or uses. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] In the prior art, when the HSS and HLR are separated and the called VoLTE user accesses the 2G network, he can only use sequential calling or simultaneous ringing, and the problem of low call connection efficiency, this solution is proposed.

[0028] In this scheme, if figure 2As shown, an i...

Abstract

The invention discloses a VoLTE (Voice over LTE) user call addressing method and system and an HSS (Home Subscriber Server) and relates to the field of mobile communication. The method provided by the invention comprises the steps that the HSS receives an address inquiry request which is sent by an I-CSCF (Call Session Control Function) and is used for continuing a called VoLTE user; the HSS judges whether the called VoLTE user registers for a 2G network or not according to VoLTE user registration information sent by an HLR (Home Location Register) and returns continuing network element address information, so the I-CSCF continues a call to the 2G network according to the continuing network element address information when the called VoLTE user registers for the 2G network. According to the method, the system and the HSS, a communication interface is increased between the HSS and the HLR, and when the VoLTE user registers for the 2G network, the HLR informs the HSS of the fact, so the HSS can instruct a follow-up continuing network element to continue the call to the 2G network. The called party continuing problem occurring when the HSS and the HLR are separated and the called VoLTE user accesses the 2G network is solved, and the call continuing efficiency is improved. A call continuing process is no longer finished through an access domain selection server, so the signal cost is reduced.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a VoLTE user call addressing method, system and HSS. Background technique [0002] In the existing VoLTE (Voice over LTE, voice service based on LTE) call solution, HSS (Home Subscriber Server, Home Subscriber Server) and HLR (Home Location Register, Home Location Register) are jointly established, HSS / HLR co-setup can solve the problem when the called user registers in a 2G (second generation mobile communication system) network such as GSM (Global System for Mobile Communication, Global System for Mobile Communication) or CDMA (Code Division Multiple Access, Code Division Multiple Access) network For the call connection problem, when the HSS and HLR are separated, it is difficult for the HSS to determine the network where the VoLTE user is currently located. It can only use sequential calls or simultaneous ringing, which is very inefficient. In addition, if figure...
