Abstract

A system includes a non-transitory computer readable medium configured to store instructions thereon; and a processor connected to the non-transitory computer readable medium. The processor is configured to execute the instructions for configuring a first service type mobility management entity corresponding to a first predetermined service at a location and connectable to first user equipment subscribed for the first predetermined service, configuring a second service type mobility management entity corresponding to a second predetermined service different from the first predetermined service at the location and connectable to second user equipment subscribed for the second predetermined service, and performing, in response to determining that the first service type mobility management entity fails to connect to the first user equipment, a switchover of a connection for the first user equipment to connect to a different first service type mobility management entity at a different location.

First claim

What is claimed is:

1 . A system, comprising:
a non-transitory computer readable medium configured to store instructions thereon; and a processor connected to the non-transitory computer readable medium, wherein the processor is configured to execute the instructions for:
configuring a first service type mobility management entity corresponding to a first predetermined service at a location, the first service type mobility management entity connectable to first user equipment subscribed for the first predetermined service;
configuring a second service type mobility management entity corresponding to a second predetermined service different from the first predetermined service at the location, the second service type mobility management entity connectable to second user equipment subscribed for the second predetermined service; and
performing, in response to determining that the first service type mobility management entity fails to connect to the first user equipment, a switchover of a connection for the first user equipment to connect to a different first service type mobility management entity at a different location,
wherein the processor is configured to execute the instructions for: in response to determining that the first and second service type mobility management entities fail to connect to the first and second user equipment, respectively,
performing the switchover of the connection for the first user equipment to connect to the different first service type mobility management entity at the different location, and
performing a second switchover of a connection for the second user equipment to connect to a different second service type mobility management entity at the different location, or
the processor is configured to execute the instructions for: in response to determining that the first service type mobility management entity fails to connect to the first user equipment and receiving a request of connecting new first user equipment subscribed for the first predetermined service, selecting the different first service type mobility management entity at the different location to connect to the new first user equipment, or the processor is configured to execute the instructions for: in response to determining that the first service type mobility management entity fails to connect to the first user equipment and the second service type mobility management entity remains connected to the second user equipment, performing the switchover of the connection for the first user equipment to connect to the different first service type mobility management entity at the different location while maintaining the connection between the second service type mobility management entity and the second user equipment to allow the second service type mobility management entity at the location to connect to new second user equipment, or in response to a determination that the first and second service type mobility management entities at the location fail to connect to the first and second user equipment, respectively, the processor is configured to execute the instructions for: in response to determining that one of the first or second service type mobility management entities becomes connectable, performing a switchover of a connection for one of the first or second user equipment to connect to said one of the first service type mobility management entity or the second service type mobility management entity.

2 . The system of claim 1 , wherein
the processor is configured to execute the instructions for: in response to determining that the first and second service type mobility management entities fail to connect to the first and second user equipment, respectively,
performing the switchover of the connection for the first user equipment to connect to the different first service type mobility management entity at the different location, and
performing the second switchover of the connection for the second user equipment to connect to the different second service type mobility management entity at the different location, and
in response to determining that the first and second service type mobility management entities at the location fail to connect to the first and second user equipment, respectively, the processor is configured to execute the instructions for:
in response to determining that the first service type mobility management entity becomes connectable and the second service type mobility management entity still fails to connect to the second user equipment, performing a switchover of a connection for the first user equipment to connect to the first service type mobility management entity while maintaining the connection between the different second service type mobility management entity at the different location and the second user equipment to allow the different second service type mobility management entity at the different location to connect to new second user equipment.

3 . The system of claim 1 , wherein the first service type mobility management entity is configured to handle the first predetermined service only, the first predetermined service including a wideband network service.

4 . The system of claim 1 , wherein the second service type mobility management entity is configured to handle the second predetermined service only, the second predetermined service including a narrowband network service.

5 . The system of claim 1 , wherein the processor is configured to execute the instructions for instructing a transmitter to transmit a result of the switchover to an external device.

6 . The system of claim 1 , wherein the processor is configured to execute the instructions for selecting the first service type mobility management entity to connect to the first user equipment while selecting the different second service type mobility management entity at the different location to connect to the second user equipment.

7 . A method, comprising:
configuring a first service type mobility management entity corresponding to a first predetermined service at a location, the first service type mobility management entity connectable to first user equipment subscribed for the first predetermined service; configuring a second service type mobility management entity corresponding to a second predetermined service different from the first predetermined service at the location, the second service type mobility management entity connectable to second user equipment subscribed for the second predetermined service; and performing, in response to determining that the first service type mobility management entity fails to connect to the first user equipment, a switchover of a connection for the first user equipment to connect to a different first service type mobility management entity at a different location, wherein the method further comprises: in response to determining that the first and second service type mobility management entities fail to connect to the first and second user equipment, respectively,
performing the switchover of the connection for the first user equipment to connect to the different first service type mobility management entity at the different location, and
performing a second switchover of a connection for the second user equipment to connect to a different second service type mobility management entity at the different location, or
in response to determining that the first service type mobility management entity fails to connect to the first user equipment and receiving a request of connecting new first user equipment subscribed for the first predetermined service, selecting the different first service type mobility management entity at the different location to connect to the new first user equipment, or in response to determi
