Problems solved by technology

[0005] Furthermore, if the IMS registration and identity authentication fail, the 3GPP standard processing method is that the terminal initiates an IMS emergency call request through the terminal identifier, which is commonly referred to as an IMS emergency call without a SIM terminal. However, at this time, the network side It is possible that IMS emergency calls are not supported, and when IMS emergency calls are not supported, the calls fall back to the CS network
[0006] Apparently, the above-mentioned emergency call processing procedure without a SIM terminal is too cumbersome. Since the terminal cannot know the network capability, that is, the ability of the network to support IMS emergency calls, it must go to the last step in accordance with the standard process to decide what method to use and what kind of method to use. The network provides emergency call services for terminals. Therefore, the existing emergency call processing flow for users without a card increases network useless signaling and increases the network burden. until timely rescue

Abstract

The embodiment of the invention discloses an information processing method, which is applied to a mobility management entity (MME). The method comprises the following steps: when attachment of a target terminal to a corresponding network is detected, determining capability information indicating that the network supports IMS (IP Multimedia Subsystem) anonymous emergency call, wherein the network is used for representing a network currently visited by the target terminal; setting a calling capability parameter according to the capability information indicating that the network supports the IMS anonymous emergency call; and transmitting the calling capability parameter to the target terminal. The embodiment of the invention also discloses a mobility management entity and a terminal.

Description

technical field [0001] The present invention relates to information processing technology, in particular to an information processing method, a mobile management entity, and a terminal. Background technique [0002] An emergency call means that the user uses the terminal to dial 112, 110, 119, 120 and other alarm or emergency calls, and countries stipulate that regardless of whether the terminal is inserted into a subscriber identity module (SIM, Subscriber Identity Module) or whether it is in arrears, the operator must provide for the user. Provide an available network and quickly provide users with effective emergency call services. [0003] Usually, for an operator, it is possible to provide users with an emergency call service through a client / server (CS) network, and to provide users with an emergency call service through a VoLTE (Voice over LTE) network; here, the The emergency call is called a CS emergency call, and the emergency call provided through the VoLTE netwo...
