Problems solved by technology

However, the handover between Wi-Fi and LTE only involves the EPS (envolved packet switched) domain, and the IMS cannot perceive that the access type of the domain where the UE is located has changed, so that after the UE is handed over, the billing of the UE and when a new call is received There will be problems with the called domain selection

Embodiment Construction

[0133] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0134] The Wi-Fi mentioned in this application is actually a broad concept, which has almost become a synonym for WLAN. The protocol standards of WLAN include IEEE802.11b, IEEE802.11a, IEEE802.11g, IEEE802.11e, IEEE802.11i, WAP, etc. Wi-Fi is a brand of WLAN, mainly using the IEEE802.11b protocol. Since the name of WiFi has been deeply rooted in the hearts of the people, people basically regard Wi-Fii as another name for WLAN. When...

Abstract

The embodiment of the invention provides a communication method, user equipment (UE) and a communication device of the user equipment. According to the method, an IMS (IP multimedia subsystem) can perceive that the UE is switched, so that subsequent charging and called domain routing is facilitated. In one embodiment, the UE initiates a re-registration process after finishing switching between WiFi and LTE (Long Term Evolution), and carries UE switching related information to an application server in the IMS through a registration request; in another embodiment, after the UE finishes switching between WiFi and LTE, a P-CSCF (Proxy-Call Session Control Function) perceives that the UE is switched according to an IP-CAN (IP-Connectivity Access Network) conversation process, an IP-CAN change event, an RAT- change event or the like, and the P-CSCF notifies the switching information of the UE to the application server in the IMS through a NOTIFY request, a MESSAGE request, an INFO request, an INVITE request and the like.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication method, user equipment and communication device in audio / video services. Background technique [0002] With the increasing number of Wi-Fi access points and the increasing popularity of VoIP (Voice over Internet Protocol), the WiFi voice solution (commonly called VoWiFi, Voice over WiFi) formed by the integration of Wi-Fi and VoIP is developing rapidly with application. VoWiFi (also known as VoWLAN in the industry) refers to the provision of VoIP services through Wi-Fi. Its technical advantage is that it combines the advantages of VoIP and mobile phones. It has both the low price of VoIP and powerful value-added functions, and the roaming of mobile phones convenience. In many areas, Wi-Fi networks are already very popular, and those enterprises that do not currently have Wi-Fi networks can quickly deploy a Wi-Fi network at a low cost. People can use IP ph...
