Problems solved by technology

[0004] After analyzing the existing technology, the inventor found that: when the MME in the MME Pool fails, the existing mechanism can only restore the calling service of the user attached to the faulty MME, but the called service of the user cannot be restored
The reason is that after the S-GW receives the user's downlink data, since the user is in an idle (IDLE) state, the S-GW needs to first notify the MME to which the user is attached to page the user, and the downlink can only be done after the connection is established. Send called service data, and when the MME attached to the user fails, the called service of the user will fail due to the inability to deliver paging
Only when the user initiates a service or initiates a periodic routing area update, and reattaches to another MME, can the called service be restored. This time is usually long, usually 1-2 hours. During this period, the called service of the user will not be recoverable, greatly affecting the user experience

Embodiment 1

[0033] see image 3 , the embodiment of the present invention also provides a method for restoring services, specifically including:

[0034] 301: The user attaches to MME1, specifically, the MME1 may be an MME in the mobility management network element pool;

[0035] 302: MME1 creates PDP context information on the S-GW, and backs up the location information of the MME1 user on the S-GW or the backup device. The location information usually refers to the information stored on the MME when the user is attached to the MME. location-related information, including but not limited to: user ID, user status, routing area information, etc.; when the location of the user changes, MME1 updates the location information of the MME1 user backed up on the S-GW or the backup device in a timely manner;

[0036] Wherein, the created PDP context information is usually the default PDP context information, and in actual application, the default PDP context information can also be adjusted as re...

Embodiment 2

[0060] see Figure 4 , the embodiment of the present invention also provides a device for restoring services, specifically including:

[0061] A detection module 401, configured to detect whether the first MME fails;

[0062] A search module 402, configured to search for a user attached to the first MME in locally pre-created context information when the detection module 401 detects a failure of the first MME;

[0063] A selection module 403, configured to select a second MME that has not failed for the user found by the search module 402;

[0064] The notification module 404 is configured to send a notification to the second MME selected by the selection module 403, and the notification is used for the second MME to provide services for the user.

[0065] Wherein, the detection module 401 specifically includes:

[0066] The heartbeat detection unit is used to detect whether a heartbeat message from the first MME is received within a specified time, and if it is received, i...

Embodiment 3

[0085] see Figure 5 , the embodiment of the present invention also provides a system for restoring services, including: a first MME 501, an apparatus for restoring services 502, and a second MME 503;

[0086] The first MME 501 is used to pre-create the context information on the device 502, and back up the location information of the user attached to the first MME 501;

[0087] The above-mentioned means 502 is configured to detect whether the first MME 501 is faulty, and when detecting that the first MME 501 is faulty, search for a user attached to the first MME 501 in the local pre-created context information, and select The second MME 503 that has not failed sends a notification to the second MME 503, requesting the second MME 503 to provide services for the user;

[0088] The second MME 503 is configured to obtain the location information of the user after receiving the notification sent by the device 502, and notify the user to attach to the second MME 503 according to t...

Abstract

The invention discloses a method, a device and a system for resuming service, belonging to the technical field of telecommunication.The method comprises the following steps: detecting whether a first mobility management network element is out of order; when the first mobility management network element is detected to be out of order, searching users attached to the first mobility management network element in locally pre-established context information, choosing a second mobility management network element which is not out of order for the searched users; issuing notifications to the second mobility management network element, wherein the notifications are used for the second mobility management network element to provide service for the users.The device comprises a detection module, a searching module, a choosing module and a notification module.The system comprises the first mobility management network element, a device for resuming service and the second mobility management network element.The invention realizes resumption of service, improves resumption speed of service and enhances user experience.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method, device and system for restoring services. Background technique [0002] In SAE (System Architecture Evolution, System Architecture Evolution) network, MME (MobilityManagement Entity, Mobility Management Network Element) is responsible for the mobility management of the control plane, including user context and mobility state management, assigning user temporary identities, and so on. In the prior art, multiple MMEs are used to form an MME Pool (mobility management network element pool), so as to realize network disaster recovery. Among them, E-UTRAN (Evolved Universal mobile telecommunications system Terrestrial Radio Access Network, Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network) is respectively connected to all MMEs in the MME Pool to realize the wireless access function, which is similar to other wireless access met...
