Embodiment 1

[0045] In step 201, the UE sends an attach request message to the serving MME, and initiates a network attach process.

[0046] 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).

[0047] In step 202, the serving MME performs authentication processing on the UE based on the learned subscription information of the UE.

[0048] Step 203: After the serving MME successfully authenticates the UE, it initiates the UE's location update process and subscription data insertion process to the HSS based on existing specifications, and updates the UE's location information on the HSS.

[0049] Step 204, the serving MME determines whether the service area can provide normal s...

Embodiment 2

[0061] 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:

[0062] In step 301, the UE sends a tracking area update request message to the serving MME, and initiates a tracking area update process.

[0063] The tracking area update request message may include information such as user identifier (user temporary identifier GUTI), last visited tracking area identifier (lasted visited TAI) and other information specified in relevant specifications.

[0064] Step 302, the serving MME obtains the user subscription data of the UE from the source MME where the tracking area M is located, and performs authentication processing on the UE.

[0065] Step 303: After the serving MME successfully authenticates the UE, based on the existing specifications, it sends a bearer creation request message to the Serving GW, instructing the Serving GW to perform the request and respo...

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, whichcontains 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 toobtain 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 (...
