Problems solved by technology

[0008] It can be seen from the above that some protocol entities and sublayer functions carried by DRB are allocated to DBS base stations for implementation, and the rest of protocol entities and sublayer functions carried by DRB are allocated to CBS for implementation. Since DBS does not have control plane functions, Only after the protocol entity in the DBS is resource-configured according to the QoS requirements carried by a DRB, the data signaling separation network can operate effectively. Therefore, it is data The key technology for the effective operation of the signaling separation network. However, there is no effective solution for resource allocation of the protocol entities in the DBS according to the QoS requirements carried by the DRB.

Embodiment 1

[0119] Embodiment one: specifically as image 3 As shown (where the first DBS is A and the first CBS is B):

[0120] Step 300: the core network sends a resource configuration control instruction to B, which is used to instruct B to allocate resources for at least one DRB of the target UE;

[0121] In this step, instructing B to perform resource allocation for at least one DRB of the target UE includes instructing B to perform resource allocation for the X2+ interface, air interface and S1+ interface respectively.

[0122] Step 310: B sends a resource allocation instruction to A according to the received resource configuration control instruction sent by the core network, so that A performs resource allocation for at least one DRB of the UE according to the resource configuration information carried in the resource allocation instruction;

[0123] In this step, let A perform resource allocation for at least one DRB of the UE according to the resource configuration information ...

Embodiment 2

[0135] Embodiment two: specifically as Figure 4 As shown (where the first DBS is A and the first CBS is B):

[0136] Step 400: the core network sends a resource release control instruction to B, which is used to instruct B to release resources on at least one DRB of the target UE;

[0137] In this step, instructing B to release resources on at least one DRB of the target UE includes instructing B to release X2+ interface resources, air interface resources and S1+ interface resources.

[0138]Step 410: B sends a resource release instruction to A according to the received resource release control instruction sent by the core network;

[0139] In this embodiment, the resource release instruction sent by B to A is used to make A release at least one DRB of the UE according to at least the identification information of the UE carried in the resource release instruction and the DRB identification information corresponding to at least one DRB of the resource to be released The res...

Embodiment 3

[0148] Embodiment three: specifically as Figure 5 As shown (where the first DBS is A, the second DBS is B, and the first CBS is C):

[0149] Step 500: When the UE is about to switch from A to B, C sends a resource allocation instruction to B, so that B performs resource allocation for at least one DRB of the UE;

[0150] In this step, there are many trigger conditions for C to send resource allocation instructions to B. For example, C receives the DBS pilot signals of each neighboring cell measured by the UE. At this time, if B’s pilot signals are determined The signal is strong, and then, send a resource allocation instruction to B, where C can ask the UE to periodically report the measured DBS pilot signal of each adjacent cell, or according to the service feedback of the current cell where the UE is located. The quality sends an indication to the UE, so that the UE measures the pilot signal of the DBS of the adjacent cell.

[0151] In this step, C sends a resource alloca...

Abstract

The invention relates to the technical field of mobile communication and discloses a resource distribution method and device for a data radio bear (DRB). Particularly, the method includes the steps that firstly, a first control base station (CBS) determines resource configuration information for performing resource distribution on at least one DRB of UE through a first data base station (DBS); then a first resource distribution instruction carrying the determined resource configuration information is sent to the first DBS so that the first DBS can perform resource distribution on the DRB of the UE according to the resource configuration information. In this way, even if the first DBS does not have the function of a control plane, the first DBS can perform resource configuration on at least one protocol entity in the first DBS according to the resource configuration information carried in the received first resource distribution instruction sent by the first CBS, then it can be guaranteed that a data and signaling separation network effectively operates, and according to the QoS request of the DRB, resource configuration is effectively performed on the protocol entity in the DBS.

Description

technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a resource allocation method and device for a data radio bearer DRB. Background technique [0002] Data signaling separation network is an important direction for future wireless network evolution because it can effectively increase network capacity and reduce network signaling overhead. Among them, data signaling separation refers to CP (Control Plane, control plane) and UP (User Plane). , user plane) separation. Compared with the traditional cellular network, the biggest feature of the data signaling separation network is that the traditional BS (Base Station, base station), or eNB (Evolved Node B) is physically divided into two parts: CBS (Control BS , control base station) and DBS (Data BS, data base station). Under the data signaling separation network architecture, low-speed users located within the coverage of DBS and with high data rate requirement...
