Service redundancy method and related apparatus
First Claim
1. A service redundancy method, comprising:
- sending, by a mobility management entity (MME), a request message to a domain name system (DNS) server, wherein the request message comprises a pool identity of an MME pool in which the MME is located, and wherein the request message requests to acquire MME codes (MMECs) of all MMEs in the MME pool;
receiving, by the MME, a request response message from the DNS server, wherein the request response message comprises the MMECs of all the MMEs in the MME pool;
determining, by the MME, a backup MME of the MME according to the MMECs of all the MMEs in the MME pool and a preset policy;
sending, by the MME, an interface request message to the DNS server, wherein the interface request message comprises an MMEC of the backup MME and the pool identity of the MME pool, and wherein the interface request message requests interface information of the backup MME;
receiving, by the MME, an interface response message from the DNS server, wherein the interface response message comprises the interface information of the backup MME; and
sending, by the MME according to the interface information of the backup MME, user information of user equipment (UE) attached to the MME to the backup MME.

Abstract
A service redundancy method and a related apparatus, where the method includes sending, by a mobility management entity (MME), a request message to a domain name system (DNS) server, receiving a request response message sent including MME codes (MMECs) of all MMEs in the MME pool, determining a backup MME of the MME according to the MMECs of all the MMEs in the MME pool, sending an interface request message to the DNS server, where the interface request message includes an MMEC of the backup MME and the pool identity of the MME pool, receiving an interface response message from the DNS server, where the interface response message includes interface information of the backup MME, and sending, according to the interface information of the backup MME, user information of user equipment UE attached to the MME to the backup MME.

4. A service redundancy method, comprising:
-
receiving, by a serving mobility management entity (MME), a service request message from user equipment (UE) using an evolved NodeB (eNodeB) after an MME to which the UE is attached becomes faulty, wherein the service request message comprises an identity of the UE and an identity of the MME to which the UE is attached, wherein the service request message requests the MME to which the UE is attached to provide a service for the UE, wherein the serving MME is an MME selected;
by the eNodeB to provide the service for the UE after the MME to which the UE is attached becomes faulty, and wherein the MME to which the UE is attached and the serving MME are located in a same MME pool;acquiring, by the serving MME, user information of the UE from a backup MME determined according to the identity of the UE or according to the identity of the UE and the identity of the MME to which the UE is attached; and providing, by the serving MME according to the user information of the UE, the service corresponding to the service request message for the UE. - View Dependent Claims (5, 6, 7, 8, 9, 10)

11. A mobility management entity (MME), comprising:
-
a transmitter configured to send a request message to a domain name system (DNS) server, wherein the request message comprises a pool identity of an MME pool in which the MME is located, and wherein the request message requests to acquire MME codes (MMECs) of all MMEs in the MME pool; a receiver configured to receive a request response message from the DNS server, wherein the request response message comprises the MMECs of all the MMEs in the MME pool; and a processor coupled to the transmitter and the receiver and configured to determine a backup MME of the MME according to the MMECs of all the MMEs in the MME pool and a preset policy, wherein the transmitter is further configured to send an interface request message to the DNS server, wherein the interface request message comprises an MMEC of the backup MME and the pool identity of the MME pool, wherein the interface request message requests interface information of the backup MME, wherein the receiver is further configured to receive an interface response message from the DNS server, wherein the interface response message comprises the interface information of the backup MME, and wherein the transmitter is further configured to send, according to the interface information of the backup MME, user information of user equipment (UE) attached to the MME to the backup MME. - View Dependent Claims (12, 13)

14. A serving mobility management entity (MME), comprising:
-
a receiver configured to receive a service request message from user equipment (UE) using an evolved NodeB (eNodeB) after an MME to which UE is attached becomes faulty, wherein the service request message comprises an identity of the UE and an identity of the MME to which the UE is attached, wherein the service request message requests the MME to which the UE is attached to provide a service for the UE, wherein the serving MME is an MME selected by the eNodeB to provide the service for the UE after the MME to which the UE is attached becomes faulty, and wherein the MME to which the UE is attached and the serving MME are located in a same MME pool; and a processor coupled to the receiver and configured to; acquire user information of the UE from a backup MME determined according to the identity of the UE or according to the identity of the UE and the identity of the MME to which the UE is attached; and provide, according to the user information of the UE, the service corresponding to the service request message for the UE. - View Dependent Claims (15, 16, 17, 18, 19, 20)
