Embodiment Construction

[0023] Considering the problem of fixed intranet coverage and limited coverage in related technologies, the present invention proposes to use WiMAX network for coverage. There is a local area network (Local Area Network, LAN) inside the enterprise, and it can also access the external Internet (Internet).

[0024] At present, the standard defines the layered structure of the IEEE 802.16 Medium Access Control (MAC) layer of WIMAX, which is divided into three sublayers: Service Specific Convergence Sublayer (Service Specific Convergence Sublayer), Common Sublayer ( Common Part Sublayer) and Security Sublayer (Security Sublayer).

[0025] Among them, the main function of the convergence sublayer is to be responsible for converting and mapping the external data received by its access point (SAP) to the MAC service data unit (SDU), and passing it to the MAC layer service access point (SAP), that is, Map connection-oriented public part services (MAC services) into standard types of ...

Abstract

The invention discloses a gateway device which is based on WiMAX access, the gateway comprises: a forwarding module for distinguishing business and / or business flow according to a label of a protocol under the situation of adopting an IP convergence sublayer in a WiMAX media access control layer and forwarding the business and / or the business flow after the distinction. The use of the invention can effectively solve the problem of limited internal network coverage in the related technologies, simply and effectively distinguish internal network data and external network data and further ensurethe correct transmission of business data.

Description

technical field [0001] The present invention relates to the communication field, and in particular, designs a gateway device based on Worldwide Interoperability for Microwave Access (WiMAX for short) access. Background technique [0002] In some enterprises, it often happens that the inside of the enterprise is covered by an intranet, and users within the enterprise can further access an external network (for example, access to the Internet (Internet)) through the intranet. [0003] Currently, enterprise intranets mainly use wired networks. Therefore, the coverage area of ​​the intranet within the enterprise will be very limited. And, if the user in the enterprise holds a mobile terminal for office work, once the user leaves the coverage of the enterprise intranet, for example, leaves his office area, at this moment, even if the user is still in a place very close to his office area, but However, they cannot continue to use the company's intranet. [0004] It can be seen ...
