Embodiment Construction

[0028] In order to realize the second layer between LTE-LAN-AP (hereinafter referred to as AP) and LTE-LAN-UE (terminal in LTE-LAN ​​system, hereinafter referred to as UE) and LTE-LAN-GW (hereinafter referred to as GW) Intercommunication of data packets. In the embodiment of the present invention, when the AP receives the first data packet sent by the first network element, it obtains the identification information of the UE according to the first data packet, and obtains the UE identification information according to the identification information of the UE. Generate layer 2 identification information of the second data packet, and generate a corresponding second data packet based on the obtained layer 2 identification information and the received first data packet, and then send the second data packet to the AP The second network element.

[0029] Wherein, the first network element may be a UE or a GW, and the second network element may be a GW or a UE.

[0030] In this emb...

Abstract

The present invention relates to the field of telecommunications, and discloses a message forwarding method and device based on LTE-LAN that enable a layer-two-based addressing technique to realize communication between an AP and other network elements in an LTE-LAN system. The method comprises: an AP receives a first data message from a first network element, acquires the identifying information of a UE and the layer-two identifying information configured corresponding to the identifying information of the UE, generates a second data message on the basis of the first data message, and transmits the second data message to a second network element according to the layer-two identifying information, the first network element and the second network element being a UE and a GW respectively, a GW and a UE respectively, or both GWs. The method thus solves the layer-two data message forwarding problem in LTE-LAN systems, enables communication between UEs, APs, and GWs, and reduces air interface expenditure. Also, an AP has no need for IP-layer forwarding functions, thereby effectively lowering AP manufacturing costs, and reducing the cost of LTE-LAN system network deployment, operation, and maintenance.

Description

technical field [0001] The present invention relates to the communication field, in particular to an LTE-LAN-based message forwarding method and device. Background technique [0002] With the development of communication technology, the requirements for the service quality of communication network are increasing day by day. In order to further improve the data processing efficiency and reduce the data processing cost on the basis of the existing network, a new network architecture is designed, called LTE-LAN ​​( Long Term Evolution-LAN, Long Term Evolution Local Network). refer to figure 1 As shown, in the LTE-LAN ​​system, the LTE-LAN-AP (wireless access point in the LTE-LAN ​​system) uses the existing LTE underlying transmission and access technology to provide the terminal with a wireless data link, thereby providing the terminal with Communication services guaranteed by QoS. Both LTE-LAN-AP and terminals realize their respective functions based on the underlying commu...
