Step 501: The source primary base station of the user equipment transmits a handover request message to the target primary base station, and the handover request message is the identification indication information or service indication in the serving base station before the handover of the user equipment. Information, whereby the target primary base station forwards the identification instruction information or the service instruction information to the target secondary base station, and the target secondary base station refers to the identification instruction information or the service instruction information. In addition, a resource configuration can be performed for the service of the user equipment.

In the present embodiment, the serving base station before the handover of the user apparatus may have one primary base station (primary base station 1 in the scenario of FIG. 4B), one primary base station and one Secondary base stations (primary base station 1 and secondary base station in the scenario of FIG. 4A, primary base station 1 and secondary base station 1 in the scenario of FIG. 4C) may be included.

In one implementation method of the present embodiment, the source primary base station of the user apparatus transmits identification instruction information in the serving base station before the handover of the user apparatus to the target primary base station of the user apparatus. Among them, the identification instruction information in the serving base station before the handover of the user apparatus includes a specific identifier of the user apparatus (as described in the first embodiment) and / or a source primary base station of the user apparatus. And / or an identifier of the source secondary base station of the user apparatus and / or an identifier of the source primary base station and / or an identifier of the source secondary base station.

Corresponding to the scenario of FIG. 4A, when the primary base station 1 transmits a handover request message to the primary base station 2, the serving base station before the handover of the user apparatus (primary base station 1 and secondary base station) Identification instruction information is transmitted to the primary base station 2, the identification instruction information here is an identifier in the primary base station 1 of the user equipment and / or a joint in the primary base station 1 and secondary base station of the user equipment An identifier under a service mode and / or an identifier of the primary base station 1 and / or an identifier of the secondary base station may be included.

  Among them, the identifier of the primary base station 1 is the ID of the primary base station 1 and / or the identifier of a cell that provides services to the user equipment under the primary base station 1, for example, PCI, ECGI (E-UTRAN Cell Global Identifier).

Corresponding to the scenario of FIG. 4B, when the primary base station 1 transmits a handover request message to the primary base station 2, identification instruction information in the serving base station (primary base station 1) before the handover of the user apparatus To the primary base station 2, and the identification instruction information here may include a user identifier in the primary base station 1 of the user apparatus and / or an identifier of the primary base station 1.

And / or the identifier of the primary base station 1 under the joint service mode and / or
Alternatively, the identifier of the secondary base station 1 may be included.

Among them, the identifier of the base station (for example, the identifier of the primary base station 1 or the identifier of the secondary base station 1) is the ID of the base station and / or the cell that provides services to the user equipment under the base station. An identifier such as PCI or ECGI (E-UTRAN Cell Global Identifier) may be used.

  In this embodiment, the source primary base station of the user apparatus sends identification instruction information (identifier) under the joint service mode of one or more base stations before the handover to the target primary base station of the user apparatus. And the target primary base station forwards it to the target secondary base station of the user equipment, whereby the target secondary base station of the user equipment refers to the information and the service requested by the user equipment Resources can be configured for For example, when the target secondary base station of the user apparatus has already provided some services to the user apparatus before the handover of the user apparatus, the target secondary base station after the handover of the user apparatus Since no resources are configured for these services of the user equipment, reservation of duplicate resources can be avoided.
