Abstract

The present invention relates to a communication method for an access control device in a network environment where a cellular network and a wireless local area network are integrated, comprising the following steps: receiving an uplink data packet from a user equipment; obtaining the uplink data packet from the received uplink data packet The destination address of the uplink data packet; determine the attribution of the destination address, if the destination address belongs to the fixed network segment, route the uplink data packet to the fixed access network through the network address translation function; if the destination address belongs to the network segment of the mobile core network, the uplink data packet is routed to the mobile core network through a network address translation function. The method of the invention can simply integrate the wireless local area network and the wireless core network, and simultaneously reduce the load of the cellular network and the wireless core network. In addition, adopting this method does not affect other parts in the network, and has the advantage of good compatibility.

Description

technical field [0001] The present invention relates to a mobile communication network, and more specifically relates to a communication method in a network environment where a cellular network and a wireless local area network are integrated. Background technique [0002] With the development of mobile networks, more and more smart terminals access mobile data services through mobile communication networks, which leads to increased loads on mobile access networks and core networks. However, the capacity of the mobile access network and core network cannot keep up with the explosive growth of user data services, which will easily cause network congestion or even collapse, especially in areas where a large number of users access data services at the same time. Therefore, the operator hopes to find an efficient method that can reduce the load of the mobile access network and the mobile core network. [0003] At the same time, Wi-Fi technology is developing rapidly. Since Wi-...
