- Embodiment 1 is a diagrammatic representation of Embodiment 1:
- FIG. 2 is a flow chart of the UE acquiring emergency service information in the first embodiment, which includes the following steps:
- Step 201 The UE initiates a network attach procedure, and sends an attach request message to the serving MME.
- the attach request message includes the UE identifier and other information required for attachment, such as an attachment type, a UE network capability, and related information for requesting the UE to allocate an address of the PDN network after attachment.
- the UE identity can be a permanent identity of the user (IMSI, International Mobile) Subscriber Identity ) or Globally Unique Temporary Identity (GUTI).
- Step 202 The serving MME performs authentication processing on the UE based on the learned UE subscription information.
- Step 203 After the service MME successfully authenticates the UE, the UE updates the location update process and the subscription data insertion process of the UE to the HSS based on the existing specifications, and updates the location of the UE on the HSS.
- Step 204 The serving MME determines, according to the acquired subscription data, whether the normal service can be provided for the UE. If not, step 205a is performed; if yes, step 205b is performed.
- the service of the UE can be performed globally, so the serving MME can provide services for the UE; but if the UE is a regional subscription user, After the UE moves to the non-contracted area, the serving MME of the non-contracted area will not provide services for the UE according to the subscription data.
- the serving MME is the MME that processed the last attachment of the UE
- the subscription data of the UE is temporarily stored on the serving MME. Otherwise, the serving MME may learn from the GUTI sent by the UE that the last attachment of the UE is processed.
- the source MME obtains the subscription data of the UE from the source MME, so as to avoid acquiring the subscription data of the UE from the upper-level user subscription server (HSS), so as to reduce the processing load of the HSS.
- HSS upper-level user subscription server
- Step 205a The serving MME makes an attach rejection decision, and returns a message indicating that the attach update fails, that is, an attach reject message, and the attach reject message carries the emergency service information supported by the network that the UE requests to attach. Then, step 206 is performed.
- Step 205b The serving MME initiates a process of establishing a default bearer to the Serving GW according to the existing specifications, and establishes a default bearer between the Serving GW and the PDN GW, and after receiving the message indicating that the default bearer is successfully returned by the Serving GW, The UE returns an Attach Accept message indicating that the attach update is successful, and the attach accept message includes the UE successfully identified by the specification, the default bearer ID (EPS bearer ID), and the tracking area identifier list.
- EPS bearer ID the default bearer ID
- the emergency service information supported by the network to which the UE is attached is further carried, and then step 206 is performed.
- Step 206 The UE receives and parses the message carrying the emergency service information returned by the service MME, and stores the parsed emergency service information, and ends the process.
- the message that is received by the UE and carries the emergency service information is an attach accept message or an attach reject message.
- the obtained emergency service information supported by the network may be sent to the network side.
- the subsequent serving MME may further initiate a location update process of the UE to the HSS, and interact with the HSS.

- a user identification user temporary identification GUTI
- a last visited tracking area identifier lasted visited TAD, etc.
- Step 302 The serving MME obtains the subscription data of the UE from the source MME where the tracking area M is located, and performs authentication processing on the UE.
- Step 303 After the serving MME successfully authenticates the UE, the serving MME sends a request to create a bearer request message to the Serving GW according to the existing specifications, and instructs the Serving GW to perform a request and response process for updating the bearer to the PDN GW. After the update bearer is completed, the Serving GW sends the Serving GW to the serving MME. Returns a create bearer response message indicating that the update bearer is complete.
- Step 304 After receiving the create bearer response message returned by the Serving GW, the serving MME initiates a location update process and a subscription data insertion process to the HSS based on the existing specifications, and interacts with the HSS to update the location and bearer information of the UE.
- Step 305 The serving MME determines, according to the subscription data of the UE obtained from the source MME, whether the normal service can be provided for the UE. If not, step 306a is performed; if yes, step 306b is performed.
- Step 306 The MME makes an attach rejection decision, and returns a Tracking Area Update Reject message indicating that the attachment fails, and the message carries the emergency service information supported by the network, and then performs step 306.
- Step 306b The serving MME returns a Tracking Area Update Accept message indicating that the tracking area update is successful, and the message further carries the information such as the user temporary identifier GUTI and the tracking area identifier list. There is emergency service information.
- the emergency service information includes an emergency call number and an emergency call.
- the GUTI in the tracking area update accept message is allocated by the serving MME, and steps The GUTI in 301 is different.
- Step 307 The UE receives and parses the message carrying the emergency service information returned by the service MME, and stores the parsed emergency service information, and ends the process.
- the message that the UE receives the emergency service information is a tracking area update accept message or a tracking area update reject message.
