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 re...

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 present invention relates to the field of mobile communication technology, and discloses a DRB resource allocation method and device, specifically: the first CBS first determines the resource configuration information that the first DBS performs resource allocation for at least one DRB of the UE, and then, Sending the first resource allocation indication carrying the determined resource configuration information to the first DBS, so that the first DBS performs resource allocation for at least one DRB of the UE according to the resource configuration information, so that even if the first DBS does not have control According to the above functions, the first DBS can also configure resources for at least one protocol entity in the first DBS according to the resource configuration information carried in the received first resource allocation instruction sent by the first CBS, thereby ensuring data signaling The separation network operates effectively, and effectively realizes the resource allocation of protocol entities in the DBS according to the QoS requirements carried by the DRB.

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 requirements w...
