Problems solved by technology

[0055] In an actual network, MME or SGSN may fail for some reason and cause restart or downtime
When the mobility management unit restarts or crashes, it will not be able to contact the UE, resulting in the UE being unable to receive paging services

Embodiment 1

[0122] The application scenario of Embodiment 1 of the present invention is: the UE is in an idle state under both the MME and the SGSN, the MME fails to restart or cannot work normally, and the UE receives an IMSI paging. Figure 7 It is a flow chart of the user equipment paging method when the mobility management unit fails or restarts according to Embodiment 1 of the present invention, as shown in Figure 7 As shown, the user equipment paging method when the mobile management unit fails or restarts in this example mainly includes the following steps:

[0123] Step 701, after the MME restarts or fails to work normally, the MSC receives the terminal call service, and the MSC reselects an MME or an MME that has recovered from the failure and sends a CS paging message, which carries the IMSI of the UE;

[0124] Step 702, after the MME receives the CS paging message, because the MME has no UE-related information, the MME uses the IMSI for paging, and the MME sends the IMSI pagin...

Embodiment 2

[0133] The application scenario of Embodiment 2 of the present invention is: the UE is in an idle state under both the MME and the SGSN, the MME fails to restart or cannot work normally, and the UE receives P-TMSI paging. Figure 8 It is a flow chart of the user equipment paging method when the mobility management unit fails or restarts according to Embodiment 2 of the present invention, as shown in Figure 8 As shown, the user equipment paging method when the mobile management unit fails or restarts in this example mainly includes the following steps:

[0134] Step 801, after the MME restarts or fails to work normally, the MSC receives the terminal call service, and the MSC reselects an MME or an MME that has recovered from the failure and sends a CS paging message, which carries the IMSI of the UE;

[0135] Step 802, after the MME receives the CS paging message, because the MME has no UE-related information, the MME uses the IMSI for paging, and the MME sends the IMSI paging...

Embodiment 3

[0152] The application scenario of Embodiment 3 of the present invention is: the UE is in an idle state under both the MME and the SGSN, the SGSN fails to restart or cannot work normally, and the UE receives the S-TMSI paging. Figure 9 It is a flow chart of the user equipment paging method when the mobility management unit fails or restarts according to Embodiment 3 of the present invention, as shown in Figure 9 As shown, the user equipment paging method when the mobile management unit fails or restarts in this example mainly includes the following steps:

[0153] Step 901, after the MSC receives the terminal call service, the MSC sends a CS paging message to the MME, and the message carries IMSI, TMSI, and location information;

[0154] Step 902, MME sends S-TMSI paging to eNodeB;

[0155] Step 903, the eNodeB forwards the S-TMSI paging to the UE;

[0156] Step 904: The MME reselects a normal SGSN. This SGSN can be another normal SGSN or a SGSN that has been restarted and...

Abstract

The invention discloses a user equipment paging method when a mobile management unit fails or restarts, comprising: when the air interface signaling reduces the ISR function activation, when it is determined that the mobile management unit registered by the user equipment UE fails or restarts, the UE does not The registered mobility management unit or the restarted mobility management unit implements paging for the UE. The invention also discloses a user equipment paging system when the mobility management unit implementing the above method fails. The invention ensures that the UE can be paged when the MME or the SGSN fails or restarts, and avoids the phenomenon that the mobility management unit in the CS service cannot contact the UE after restarting or downtime. The invention ensures the continuity and stability of the UE business and improves the service quality of the CS business.

Description

technical field [0001] The present invention relates to user equipment (UE, User Equipment) paging technology under the function of air interface signaling reduction (ISR, Idle mode Signaling Reduction) in System Architecture Evolution (SAE, System Architecture Evolution), especially relates to a mobile management unit failure Or user equipment paging method and system when restarting. Background technique [0002] With the sudden emergence of the World Interoperability for Microwave Access (WiMax, World Interoperability for MicrowaveAccess) technology, the third-generation mobile communication system must improve its network performance and reduce network construction and operation costs in order to maintain its competitiveness in the field of mobile communications. . Therefore, the standardization working group of the 3rd Generation Partnership Project (3GPP, 3rdGeneration Partnership Project) is currently working on researching the packet switching core network (PS Core,...
