Embodiment 1

[0062] Such as figure 2 As shown, it is a schematic diagram of a load balancing system provided in Embodiment 1 of the present application, wherein a customer edge device (Customer Edge, CE) is a transmission network element between an eNB and a VMME; a virtual layer (Hypervisor) is a The intermediate software layer between the operating system and the operating system is used to virtualize various hardware resources.

[0063] The eNB 201 is configured to, after receiving the first request sent by the UE, send the first request to the virtual machine allocator; wherein, the first request is an access request or a handover request. In the specific implementation process, when the UE enters the coverage area of ​​the MME POOL, it can send the first request to the eNB. Here, if the UE sends the ATTACH signaling to the eNB, the first request is an access request; if the UE sends the eNB What is sent is TAU signaling, and the first request is a handover request.

Embodiment 2

[0074] Such as image 3 As shown, it is a schematic diagram of another load balancing system provided in Embodiment 2 of the present application.

[0075] Optionally, the VIM may detect the load information of each VM in each VMME in real time, and periodically send the detected load information to the virtual machine allocator.

[0076] In the specific implementation process, when the UE enters the coverage area of ​​the MME POOL, it can send ATTACH / TAU signaling to the eNB. After receiving the ATTACH / TAU signaling, the eNB can directly Send it to the virtual machine allocator. Further, after receiving the ATTACH / TAU signaling, the virtual machine allocator selects the VM with the lightest load to assign to the UE according to the load of each VM sent by the VIM, and assigns the ATTACH / TAU signaling is sent to the VM, and then the VM parses the received ATTACH / TAU signaling, and after completing the UE authentication and other services, it sends the ATTACH / TAU response info...

Embodiment 3

[0080] Such as Figure 4 As shown, it is a flow chart of the load balancing method provided in Embodiment 3 of the present application.

[0081] S401: After receiving the first request sent by the UE, the eNB sends the first request to the virtual machine allocator; wherein, the first request is an access request or a handover request.

[0082] S402: After receiving the first request, the virtual machine allocator determines the VM allocated to the UE according to the load information of each VM in at least one VMME, and sends indication information to the VM; the indication information is used to indicate that the VM is UEs provide services.

[0083]In the specific implementation process, the virtual machine allocator may receive the load information determined and sent by the VIM, and further, according to the received load information of each VM, select the VM with the smallest load from each VM in at least one VMME, and place the The VM with the least load is determined ...

Abstract

The invention relates to the technical field of mobile communication, especially to a load balancing system, method and device, and aims at solving the problems of a complex processing process and waste of eNB and VMME processing resources when a VM is selected for UE in the prior art. The load balancing system comprises an eNB, at least one VMME and a virtual machine distributor; each VMME comprises multiple VMs; after receiving a first request from the UE, the eNB sends the first request to the virtual machine distributor; the first request is an access request or switching request; and after receiving the first request, the virtual machine distributor determines the VM distributed to the UE according to load information of VMs in the at least one VMME, and sends indication information to the VM; the indication information indicates the VM to provide services for the UE; and after receiving the indication information, the VM sends response information to the UE via the eNB.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a load balancing system, method and device. Background technique [0002] With the development of Network Function Virtualization (NFV) technology, a core network (Evolved Packet Core, EPC) is gradually moving towards a Virtual Evolved Packet Core network (Virtual Evolved Packet Core, VEPC). The VEPC follows the architecture of the Mobility Management Entity Pool (MME POOL) in the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) to achieve load balancing of various network elements. In the VEPC, the MME POOL includes multiple virtual mobility management entities (Virtual Mobility Management Entity, VMME), and in order to improve the performance of the VMME, each VMME includes multiple virtual machines (Virtual Machine, VM). [0003] Such as figure 1 Shown is a schematic diagram of the network architecture of the MME POOL in the ...
