Abstract

The invention provides a network access system and a method. The system comprises a control panel node and a user panel node, wherein the control panel node is connected with UE via a wireless interface and is connected with a MME (Mobile Management Entity) via an S1 interface for processing control panel data; and the user panel node is connected with the UE via a wireless interface and is connected with a SGW (Service Gate Way) via an Ss interface for processing user panel data. Thus, the problems that frequent interaction happens to information between nodes when the user is switched among cells and a core network is impacted in the related technology can be solved, interaction of information between nodes is reduced, and impact on core network signaling is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a network access system and method. Background technique [0002] figure 1 It is the overall architecture diagram of the long-term evolution system (Long Term Evolution, referred to as LTE) in related technologies, such as figure 1 As shown, the architecture includes: Mobility Management Entity (MME for short), Serving GetWay (SGW for short). User equipment or terminal (User Equipment, UE for short) and base station (eNodeB, eNodeB for short) The UU interface is between eNBs, the S1-MME interface is between eNB and MME, the S1-U interface is between eNB and SGW, and the X2 interface is between eNBs. figure 2 It is a schematic diagram of the protocol architecture of the control plane and user plane between UE and eNB, core network (MME and SGW) of LTE in the related technology, as shown in figure 2 On the left side, the interface between UE and eNB in ​​LTE is divided into t...
