Embodiment 1

[0031] figure 1 It is a flow chart of the service request processing method provided in Embodiment 1. like figure 1 As shown, the method includes the following steps.

[0032] Step 101. The controller receives a service request notification. The service request notification is generated by the base station after receiving the service request and sent to the controller. The base station has a request flow table matching the service request.

[0033] Specifically, in a mobile communication network with an SDN architecture, the controller is responsible for controlling each network device. An important guarantee for the smooth realization of this control is the OpenFlow protocol. Through the OpenFlow protocol, the controller adds, modifies, and deletes flows to each network device. entry, so that the network device can forward the data packet according to the flow entry. Each data packet needs to find a matching flow table before processing, and the network device can process ...

Embodiment 2

[0043] figure 2 It is a flow chart of the service request processing method provided in the second embodiment. like figure 2 As shown, the method includes the following steps.

[0044] Step 201, the controller receives a service request notification, which is generated by the base station after receiving the service request and sent to the controller, and the base station has a request flow table matching the service request.

[0045] Step 202, the controller judges the processing location of the service request according to the preset service processing policy and request flow table.

[0046] Step 203, when it is judged that the processing location of the service request is the local cloud of the access network, generate a local cloud path and send it to the edge router of the access network, so that the edge router of the access network sends the service request to the access network edge router according to the local cloud path. The network-local cloud performs process...

Embodiment 3

[0061] Figure 5 It is a flow chart of the service request processing method provided in the third embodiment. like Figure 5 As shown, the method corresponds to the service request processing method provided in Embodiment 1, and includes the following steps.

[0062] Step 501, the edge router of the access network receives the service request sent by the base station.

[0063] Specifically, the mobile terminal sends out a service request, and after receiving the service request, the base station generates a service request notification and sends it to the controller. The service request notification can be carried in the form of signaling. After the base station sends the service request notification to the controller, it also sends the service request to the edge router of the access network.

[0064] Step 502, the edge router of the access network receives the path information sent by the controller. The path information is generated after the controller judges the pro...

Abstract

The present invention provides service request processing methods and a service request processing apparatus, relating to mobile communication technologies and solving a problem that an existing service request processing method may increase the network congestion probability and service response delay. The service request processing method comprises the steps that a controller receives a service request notification, wherein the service request notification is generated and sent to the controller after a base station receives a service request, and the base station has a request flow table matching the service request; the controller determines a processing position of the service request according to a preset service processing policy and the request flow table; when it is determined that the processing position of the service request is a local cloud of an access network, a local cloud path is generated and is sent to an edge router of the access network, so that the edge router of the access network sends, according to the local cloud path, the service request to the local cloud of the access network to be processed; and the service request is sent to the edge router of the access network after the base station sends the service request notification.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a service request processing method and processing device. Background technique [0002] With the continuous growth of users' demand for wireless transmission and the popularization of various communication applications such as the Internet of Things, the supporting capacity of the existing 4G mobile communication system obviously cannot meet the requirements. Therefore, the 5G mobile communication system came into being. It is based on the existing The integration and evolution of communication systems and the introduction of information wireless transmission and network technology have achieved a substantial increase in user transmission rates and system capacity. [0003] In terms of network architecture, the 5G mobile communication system will form a more flexible, intelligent, efficient and open heterogeneous converged network system based on Software Defined Networking (SD...
