Embodiment 1

[0082] Based on the above basic idea, see figure 2 , which shows that an embodiment of the present invention provides a radio bearer configuration method, which can be applied to the main serving base station side in the base station set of a virtual cell, and the method can include:

[0083] S201: When the newly added slave serving base station joins the base station set, the main server base station obtains the wireless resource information allocated by the newly added slave serving base station for the mobile station MS corresponding to the virtual cell for transmitting the signaling data protocol unit;

[0084] S202: The primary serving base station constructs the radio resource information into a signaling data protocol unit for carrying the radio resource information;

[0085] S203: The primary serving base station instructs the existing secondary serving base stations in the base station set to transmit the signaling data protocol unit to the MS.

[0086] It can be un...

Embodiment 2

[0101] Based on the same technical idea of ​​the foregoing embodiments, see Figure 4 , which shows a radio bearer configuration method provided by an embodiment of the present invention, the method may be applied to the slave serving base station side in the base station set of a virtual cell, and the method may include:

[0102] S401: when the serving base station joins the base station set, allocate radio resource information for signaling transfer to the mobile station MS corresponding to the virtual cell;

[0103] S402: The slave serving base station sends the radio resource information used for signaling transfer to the master serving base station in the base station set, so that the master serving base station constructs the radio resource information into a signaling data protocol unit and transmits it to the MS.

[0104] It can be understood that when each slave serving base station joins the base station set, it can allocate radio resource information for signaling t...

Embodiment 3

[0117] Based on the above two embodiments, see Figure 5 , which shows a detailed flow of a radio bearer configuration method provided by an embodiment of the present invention, with figure 1 The virtual cell structure in is described as an example of an application scenario. In this embodiment, Master-BS is the master serving base station, Slave-BS2 is the slave serving base station newly added to the base station set of the virtual cell corresponding to the MS, and Slave-BS1 is the slave serving base station Joining the slave serving base station of the base station set of the virtual cell corresponding to the MS, the process may include:

[0118] S501: Master-BS sends a joining invitation to Slave-BS2;

[0119] Exemplarily, the invitation to join may be used to request Slave-BS2 to join the base station set of the virtual cell corresponding to the MS;

[0120] S502: Slave-BS2 allocates radio resources for MS to transmit signaling;

[0121] Exemplarily, the radio resource...

Abstract

A radio bearer configuration method, device, and system. The method comprises: when a newly added slave-BS joins a base station (BS) group, acquiring, by a master-BS, radio resource information used for transferring signaling and allocated to a mobile station (MS) corresponding to a virtual cell by the newly added slave-BS; composing, by the master-BS, the radio resource information into a signaling data protocol unit used for carrying the radio resource information; and instructing, by the master-BS, the currently existing slave-BS in the BS group to transmit the signaling data protocol unit to the MS.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a configuration method, equipment and system for wireless bearer. Background technique [0002] With the increasing number of wireless communication user groups, its application scenarios become more and more extensive. In order to continuously improve the capabilities of broadband wireless access networks and meet business needs, it is usually adopted to deploy high-density heterogeneous The coverage area of ​​the cell is used to improve the spatial reuse rate of spectrum resources. However, due to the narrow coverage of the cell, it cannot well support the rapid movement of users. Therefore, the concept of virtual cell is introduced at present, that is, the virtual cell is dynamically constructed for the user centered on the user. Such as figure 1 A schematic diagram of the structure of a virtual cell is shown. The coverage of the virtual cell is shown as a solid c...
