Abstract
Provided are a method, a device, equipment and a storage medium for managing a mobile handover. When the method for managing the mobile handover is applied to a source secondary base station, the method includes: in response to determining to switch a set user equipment (UE) to a target base station, sending a handover request message to the target base station; and in response to receiving a handover request acknowledgement message sent by the target base station, sending a handover command message to the UE by using a signaling radio bearer (SCG SRB) of a source secondary base station side to trigger the UE to perform a random access attempt on a serving cell under the target base station.
Claims12
A management method for a mobile handover, applied to a source secondary base station, comprising:
- in response to determining to switch a set user equipment (UE) to a target base station, sending a handover request message to the target base station;
- in response to receiving a handover request acknowledgement message sent by the target base station, sending a handover command message to the UE via a secondary cell group signaling radio bearer (SCG SRB) of a source secondary base station side to trigger the UE to perform a random access attempt on a serving cell under the target base station;
- receiving a source secondary base station node release request message sent by the target base station, and forwarding the source secondary base station node release request message to the source master base station, wherein the source secondary base station node release request message contains data forwarding address information;
- and
- releasing an association relationship between the source secondary base station and the UE according to the source secondary base station node release request message, and forwarding UE-related data cached in the source secondary base station according to the data forwarding address information.
A management method for a mobile handover, applied to a source master base station, comprising:
- configuring a grant to allow a source secondary base station to enable a function of performing mobile handover management on a set user equipment (UE), wherein the configured grant at least comprises parameter information about UE wireless connection security control, comprising an encryption key of a radio bearer and an integrity protection key;
- when the source secondary base station determines to switch the set UE to a target base station, receiving a source secondary base station node release request message forwarded by the source secondary base station, wherein the source secondary base station node release request message comprises data forwarding address information;
- releasing an association relationship with the UE according to the source secondary base station node release request message;
- and
- forwarding UE-related data cached in the source master base station via the source secondary base station according to the data forwarding address information.
A management method for a mobile handover, applied to a target base station, wherein the method comprises:
- receiving a handover request message sent by a source secondary base station;
- preforming resource pre-allocation, radio resource control (RRC) configuration and context generation in the target base station on a user equipment (UE) according to a parameter in the handover request message;
- sending a handover request acknowledgement message to the source secondary base station, wherein the handover request acknowledgement message comprises an RRC configuration and context in the target base station;
- and
- sending a source secondary base station node release request message to the source secondary base station, wherein the source secondary base station node release request message is used for requesting the source secondary base station to release an association relationship between the source secondary base station and the UE and comprises data forwarding address information, such that the source secondary base station releases the association relationship between the source secondary base station and the UE according to the source secondary base station node release request message, and forwards UE-related data cached in the source secondary base station according to the data forwarding address information.
