Abstract
The present invention provides a handover method. An access node obtains mobility management entity pool MME pool information which is sent by a donor station of the access node and is used for identifying a mobility management entity MME to which a user equipment UE is attached. The access node initiates handover for the UE according to the MME pool information used for identifying the MME to which the UE is attached. The present invention further provides a communication device and a communication system.
Claims20
A method for transmitting information in a communication system, wherein the communication system comprises an access node, a donor station of the access node, and a mobility management entity (MME), and the access node accesses the MME through the donor station, the method comprising:
- receiving, by the donor station, a first message sent by the MME, wherein the first message is a handover request message or an initial context setup request message, and the first message carries a globally unique MME identifier (GUMMEI) of the MME;
- and
- sending, by the donor station, a second message to the access node, wherein
- the second message comprises at least one of a handover request message and an initial context setup request message, and
- the second message carries the GUMMEI of the MME.
A communication device, serving as a donor station of an access node, wherein
- the access node accesses a mobility management entity (MME) through the donor station;
- the device comprises a processing hardware platform executing instructions stored on a non-transitory computer-readable storage medium, and
- the instructions, when executed, cause the device to:
- receive a first message sent by the MME, wherein the first message comprises at least one of a handover request message and an initial context setup request message, and the first message carries a globally unique MME identifier (GUMMEI) of the MME;
- and
- send a second message to the access node, wherein
- the second message comprises at least one of a handover request message and an initial context setup request message, and
- the second message carries the GUMMEI of the MME.
A communication device, serving as an access node, wherein
- the access node accesses a mobility management entity (MME) through a donor station of the access node,
- the device comprises a processing hardware platform executing instructions stored on a non-transitory computer-readable storage medium, and
- the instructions, when executed, cause the device to:
- receive a first message comprising at least one of a handover request message and an initial context setup request message from the donor station, wherein the first message carries a globally unique MME identifier (GUMMEI) of the MME.
A communication device, serving as a mobility management entity (MME) in a communication system, wherein
- the communication system further comprises an access node and a donor station of the access node,
- the access node accesses the MME through the donor station, and the device comprises a processing hardware platform executing instructions stored on a non-transitory computer-readable storage medium, and
- the instructions, when executed, cause the device to:
- send a first message comprising at least one of a handover request message and an initial context setup request message to the donor station, wherein the first message carries a globally unique MME identifier (GUMMEI) of the MME.
