Abstract
A handover processing method includes obtaining, by a relay station, information, where the information is used for determining whether a mobility management entity (MME) of a user equipment is in a mobility management entity pool (MME pool) to which a neighboring eNB belongs; and determining, by the relay station, that an X2 interface between a serving eNB of the relay station and the neighboring eNB cannot be used for handover if the MME of the user equipment is not in the MME pool to which the neighboring eNB belongs. The foregoing solutions enable the relay station to initiate a correct handover procedure.
Claims13
A handover processing method, comprising:
- obtaining, by a relay station, a Globally Unique (GU) Group ID indicating a mobility management entity (MME) pool to which a neighboring eNodeB (eNB) belongs;
- determining, based on the GU Group ID, whether a MME of a user equipment served by the relay station is in the MME pool to which the neighboring eNB belongs;
- and
- determining, by the relay station, that an X2 interface between a serving eNB of the relay station and the neighboring eNB cannot be used for handover handing over the user equipment when the MME of the user equipment is not in the MME pool to which the neighboring eNB belongs.
A relay station, comprising:
- an information obtaining unit configured to obtain information pool (MME) to which a Globally Unique (GU) Group ID indicating a mobility management entity (MME) pool to which a neighboring eNodeB (eNB) belongs;
- a determining unit configured to determine, based on the GU Group ID, whether a MME of a user equipment served by the relay station is in the MME pool to which the neighboring eNB belongs;
- and a handover executing unit configured to initiate an S1 handover request message to a serving eNB of the relay station so as to hand over the user equipment from the serving eNB to the neighboring eNB by using a S 1 interface between the serving eNB and the neighboring eNB, when the MME of the user equipment is not in the MME pool to which the neighboring eNB belongs.
A handover processing method, comprising:
- obtaining, by a relay station, a Globally Unique (GU) Group ID indicating a mobility management entity (MME) pool to which a neighboring eNodeB (eNB) belongs;
- determining, based on the GU Group ID, whether a MME of a user equipment served by the relay station is in the MME pool to which the neighboring eNB belongs;
- and
- initiating, by the relay station, an S1 handover request message to a serving eNB of the relay station so as to handover hand over the user equipment from the serving eNB to the neighboring eNB by using a S 1 interface between the serving eNB and the neighboring eNB, when the MME of the user equipment is not in the MME pool to which the neighboring eNB belongs.
A communication system comprising:
- a relay station;
- and a serving eNodeB (eNB) of the relay station, wherein the relay station is configured to:
- obtain information for determining whether a (MME) of a Globally Unique (GU) Group ID indicating a mobility management entity (MME) pool to which a neighboring eNodeB belongs;
- determine, based on the GU Group ID, whether a MME of a user equipment served by the relay station is in the MME pool to which the neighboring eNB belongs and MME to which the initiating, by the relay station, an S1 handover request message to the serving eNB so as to hand over the user equipment from the, serving eNB to the neighboring eNB by using a S1 interface between the serving eNB and the neighboring eNB, when the MME of the user equipment is not in the MME pool to which the neighboring eNB belongs.
