Wireless network user access processing method, device and system

Abstract

The embodiment of the invention provides a cellular network controller. The cellular network controller comprises a wireless protocol processing module, a control decision module and a strategy issuing module, wherein the wireless protocol processing module is used for processing a wireless switching request coming from a wireless network user or wireless network access network and reporting processing results, the control decision module is used for formulating a bearing forwarding strategy of the switched user according to event information pre-stored in the cellular network controller and the processing results reported by the wireless protocol processing module, the strategy issuing module is used for issuing the bearing forwarding strategy formulated by the control decision module to a strategy execution body corresponding to the switched user for execution to enable a data package sent to the switched user to be forwarded according to the bearing forwarding strategy. The embodiment of the invention further provides a related wireless network user access processing method, device and system. By means of the scheme, signaling negotiation among multiple control entities is reduced, and network resource waste is reduced.

Description

technical field [0001] The invention relates to the field of power supply, in particular to a method, device and system for processing wireless network user access. Background technique [0002] Traditional wireless cellular networks, such as 2G / 3G / 4G communication networks, mainly include two parts: the core network and the access network. Taking the LTE system as an example, its network architecture is as follows: figure 1 shown. In the LTE network architecture, the core network mainly includes MME, S-GW, and P-GW. The MME is a mobility management unit, which handles non-access stratum (NAS) signaling between UE and CN, including bearer and link management; S- GW is the service gateway, which is the anchor point with other 3GPP standards (GSM / UMTS); and P-GW is the data gateway, which is responsible for IP address allocation, QoS, and the anchor point with non-3GPP (such as CDMA2000, WiMAX) standards. The wireless access network is mainly composed of eNodeB, which simpli...

Problems solved by technology

[0004] In a traditional cellular network, since the GTP tunnel reaches the position of the PGW, its bearer channel must also reach the position of the core network PGW. On the path from the UE to the PDN, in the active state, any two nodes must establish tunnel, and the path between the two nodes must be maintained through signaling, and when the status changes from active to idle, signaling is required to remove the tunnel. Such an operation will result in relatively large signaling overhead and great waste network resources
