Embodiment Construction

[0027] 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. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] In a mobile communication system, when UE users use data services, they usually use an Access Point Name (APN) mechanism to identify the external network that the UE wants to access (that is, the service that the UE wants to perform) , at this time, the access point device uses APN resolution to control the routing of the UE. In the communication system based on IMS network, APN is generally deployed on the gateway device of IP-CAN or logically connecte...

Abstract

The embodiment of the invention relates to a method, a device and a system for processing an urgent call service. The method comprises the following steps of: receiving an urgent call service indication, generating an urgent call service policy which contains a QoS parameter corresponding to the urgent call service according to the urgent call service indication, and assigning the urgent call service policy so as to create and/or modify a load/context for loading the urgent call service information. The embodiment of the invention can guide a loading management functional device to create and/or modify the load/context for loading the urgent call service information according to the urgent call service policy in order to enable UE to perform the urgent call service by continuing to create and/or modify the load/context for loading the urgent call service information when the UE which performs the urgent call service is switched to a limited area from a normal area, so as to expand the application area of the urgent call service.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile communications, and in particular, to a method, device and system for processing an emergency call (Emergency Call, EMC for short) service. Background technique [0002] As the core technology of the next generation network, the IP Multimedia Subsystem (IP Multimedia Subsystem, IMS for short) provides a general service platform for future multimedia applications. Utilizing the IP-Connectivity Access Network (IP-CAN for short) and the IMS network can provide emergency call services for the terminal (User Equipment, UE for short), such as: alarm service and fire alarm service. The above-mentioned IP-CAN It may be an IP network such as a General Packet Radio Service (GPRS for short) network, a Universal Mobile Telecommunications System (UMTS for short) network or an Evolved Packet System (EPS for short) network. The UE can not only perform emergency call services in the normal I...
