Embodiment 1

[0030] Embodiment 1. Embodiments of the present invention provide a network load balancing method, such as figure 1 Shown include:

[0031] S101. When it is determined that the RRC usage rate in the communication cell is greater than or equal to a preset threshold, generate configuration information for releasing the SCC according to the service type of the terminal device.

[0032] It should be noted that in practical applications, the network parameters first need to be obtained and calculated according to the network parameters; among them, the network parameters include: the current number of RRC connections Num_RRC_now of the communication cell and the maximum number of RRC connections Num_RRC_max supported by the communication cell and pass Num_RRC_now and Num_RRC_max to calculate the RRC usage rate P in the communication cell; then judge whether P is greater than or equal to the preset threshold Th, when P≥Th, it means that the resource load of the current communication...

Embodiment 2

[0036] Embodiment 2. Embodiments of the present invention provide a network load balancing method, such as figure 2 , image 3 and Figure 4 The specific implementation shown is as follows:

[0037] It should be noted that the corresponding processing procedures are different when the terminal equipment performs Non_GBR service and GBR service; therefore, what is provided in Scenario 1 is the specific implementation method when the service type of the terminal device is Non_GBR service, and the implementation method provided in Scenario 2 It is a specific implementation method when the service type of the terminal equipment is the GBR service.

[0038] Scenario 1. Embodiments of the present invention provide a network load balancing method, such as figure 2 and Figure 4 Shown include:

[0039] S1010. When it is determined that the RRC usage rate in the communication cell is greater than or equal to a preset threshold, acquire a terminal device whose RB resource usage r...

Embodiment 3

[0068] Embodiment 3. The embodiment of the present invention provides an access network device 10, such as Figure 5 Shown include:

[0069] The data processing unit 101 is configured to generate configuration information for releasing the SCC according to the service type of the terminal device when it is determined that the RRC usage rate in the communication cell is greater than or equal to a preset threshold.

[0070] The data transmission unit 102 is configured to send a control command carrying configuration information generated by the data processing unit 101 to the terminal device; wherein the configuration information includes stopping using the SCC for data transmission within a preset time.

[0071] Optionally, the service category includes: Non_GBR service; the access network device 10 such as Figure 6 The figure also includes: a data acquisition unit 103; a data acquisition unit 103, used to acquire a terminal device whose RB resource usage rate on the SCC is g...

Abstract

The embodiment of the invention provides a network load balancing method and an access network device, relates to the technical field of communication and solves the problem that in an existing carrier aggregation system, the user experience is low due to the fact that a terminal device occupies a plurality of CCs (Component Carriers) at the same time, when certain CC is in a saturation condition, no RRC connection can be established and no resource can be allocated for a new device or a new business request on the CC, and the new device cannot be accessed or the new business request cannot be timely responded. The method comprises the steps of generating configuration information for releasing SCCs (Secondary Component Carriers) according to business types of network loads when it is determined that an RRC utilization rate in a communication cell is greater than or equal to a preset threshold; and sending control instructions carrying the configuration information to the network loads. The embodiment of the invention is used for allocating the secondary component carriers.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a network load balancing method and access network equipment. Background technique [0002] Carrier aggregation (English full name: Carrier Aggregation, abbreviated: CA) technology is an important technology in a long-term evolution technology upgrade version (English full name: Long Term Evolution-Advanced, abbreviated: LTE-A). Carrier aggregation means that data of a terminal device can be simultaneously transmitted on multiple component carriers (English full name: Component Carrier, CC for short), which is equivalent to increasing the transmission bandwidth of the terminal device. In the LTE Re1-10 protocol, a terminal device can use up to 5 CCs at the same time, so that the maximum transmission bandwidth of a single terminal device can theoretically reach 100MHz, which will greatly increase the peak data transmission rate of the terminal device. [0003] A CC represe...
