Embodiment Construction

[0035] Attached below figure 2 , to further illustrate the steps of implementing the IMS-HSS local roaming control method:

[0036] Step 200: The maintenance / management personnel configure the roaming control policy for the user to use the VoWiFi voice service through the man-machine interface, that is, the conditions for the user to allow or not allow roaming based on the location and / or type of the access network.

[0037] Step 201: The maintenance / management personnel sign up the roaming restriction information to different IMS users through the camp account;

[0038] Step 202: The IMS-HSS receives the user authorization request information from the I-CSCF, and the message carries the location or type information of the user's access network;

[0039] Step 203: The IMS-HSS local roaming access control module sends a roaming capability request message to the local roaming policy configuration module to obtain whether the user has roaming capability under the location or ty...

Abstract

The invention discloses a method for implementing roaming restriction to a VoWiFi (Vocie Over WiFi) voice service. According to the method, when a user registers to an IMS (IP Multimedia System) network by a WLAN (Wireless Local Area Network) access network, the user can be independently and flexibly controlled whether to use the VoWiFi service according to the position or type of the access network where the user is positioned, thereby implementing roaming restriction to the VoWiFi (Vocie Over WiFi) service of the user. Furthermore, a control opportunity of the method occurs in a stage that the user initially registers to the IMS network, subsequent interaction of a great quantity of invalid signals is avoided, a network signaling load can be effectively reduced, and the method has a high construction value.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a method for realizing roaming restriction of VoWiFi voice service. Background technique [0002] VoWiFi (Vocie Over WiFi, voice service based on WiFi) refers to the user accessing the EPC of the operator through the WiFi network, using the non-3GPP network access standard defined in the 3GPP standard specification, and using the trusted WLAN or non-trusted WLAN access mode. Network (Evolved Packet Core, evolved packet core network), after the EPC network authentication is successful, messages such as registration / call requests are routed to the IMS network, and IMS (IP Multimedia System, IP Multimedia System, etc.) ) business, please refer to the attached figure 1 . [0003] VoWiFi involves EPC network elements and IMS network elements in the 4G mobile communication system, including HSS (Home Subscriber Server, Home Subscriber Server), SGW (Serving GateWay, Ser...
