Problems solved by technology

[0006] In actual situations, the emergency service information stored on the UE is usually only applicable to a certain fixed service area, while the range of activities of mobile users is usually not fixed. An operator or different networks of the same operator are supported by roaming agreements. When a mobile user requests emergency services, the pre-stored emergency service information is not applicable, resulting in the failure of the mobile user to request emergency services. For another example, if the service provider provides mobile users with new types of emergency services, the emergency service information stored on the UE should be updated accordingly
[0007] The prior art has not yet provided a solution for how to enable the UE to obtain emergency service information in the PS domain in a timely manner

Embodiment 1

[0043]In the first embodiment, it is assumed that the UE is reattached in a certain service area, such as being powered on, the attach update message sent by the UE to the serving MME may be an Attach Request message (Attach Request). see figure 2 , figure 2 It is a flow chart of UE obtaining emergency service information in Embodiment 1, and the process may include the following steps:

[0044] In step 201, the UE sends an attach request message to the serving MME, and initiates a network attach process.

[0045] The attach request message includes the UE identity and other information required for attaching, such as attach type, UE network capability, requesting to allocate an address for the UE to access the PDN network after attaching, and so on. The UE identity may be a permanent user identity (IMSI) or a temporary user identity (GUTI, Globally Unique Temporary Identity).

[0046] In step 202, the serving MME performs authentication processing on the UE based on the ...

Embodiment 2

[0059] In the second embodiment, it is assumed that the UE moves to another tracking area N after successfully attaching to a service area (also called Tracking Area (TA) M), so as to prevent the UE from initiating emergency services in the tracking area N The request failed, and the emergency service information stored on the UE needs to be updated. In the second embodiment, the message indicating the attachment update sent by the UE to the serving MME in the tracking area N is a tracking area update request message (Tracking Area Update Request).

[0060] see image 3 , image 3 It is a flow chart of the UE obtaining emergency service information in the second embodiment, and the process may include the following steps:

[0061] In step 301, the UE sends a tracking area update request message to the serving MME, and initiates a tracking area update process.

[0062] The tracking area update request message may include information such as user identifier (user temporary id...

Abstract

The invention provides an emergency service information obtaining method comprising the steps: user equipment (UE) transmits a message expressing attachment update to a service mobility management entity (MME); after receiving the message which expresses the attachment update and is transmitted by the UE, the service MME transmits the message expressing attachment update success or failure, which contains the emergency service information supported by an evolution packet system (EPS) network in which the service MME is positioned, to the UE; and after receiving the message expressing the attachment success or failure, the UE analyzes the emergency service information. The invention also provides the UE and the MME. The technical scheme supplied by the invention is convenient for the UE to obtain the emergency service information supported by the positioned EPS network in time and enables the UE to smoothly develop emergency services.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for acquiring emergency service information and a communication device. Background technique [0002] Emergency services such as fire alarm and emergency rescue are services that operators provide to mobile users to help users get out of trouble. It enables users to contact relevant units as soon as possible when they encounter difficulties such as human attacks, fires, and disease outbreaks. and get help. [0003] In the 3rd Generation Partnership Project (3GPP) system, the network side provides emergency services for users in the Circuit Switched (CS) domain. The continuous development of communication technology promotes the continuous evolution of the communication system architecture. Communication services based on the CS domain are gradually replaced by communication services based on the Packet Switching (PS) domain. IP-Connectivity Access Network (...
