Hybrid networking technology employing WiFi wireless local area network and LTE cellular network

Abstract

Disclosed is a hybrid networking technology employing a WiFi wireless local area network and an LTE cellular network. The design method of a network controller of a wireless local area network (WiFi), on the one hand, is provided with a wireless local area network stack prescribed by the 802 international organization, and is capable of managing base stations in the wireless local area network, on the other hand, is provided with a wide wireless cellular network core network device management function and a protocol stack prescribed by the 3GPP international organization for standardization, and is capable of supporting functions of validation, billing, service quality insurance, encryption, mobile and roaming support for user terminals according to a method defined by wide wireless cellular network, thereby achieving hybrid networking of the WiFi wireless local area network and the LTE cellular network. The hybrid networking technology between WiFi wireless local area network and LTE cellular network is advantaged by (a) utilizing two wireless base stations at the same time to achieve wireless coverage in the service area, thereby preventing repeated investment; (b) flexibly configuring user flow in two wireless sub-systems, in order to reach a plurality of effects such as load balance, service quality improvement and service redundancy improvement; and (c) greatly enlarging support ranges of user terminals.

Description

1. Technical field [0001] The application of the present invention relates to that in areas covered by multiple wireless networks using different wireless communication technologies, by adopting specific network structure technologies and communication protocols, hybrid networking and unified management of heterogeneous wireless networks can be realized, and mobile users can be supported in Seamless vertical handover in heterogeneous networks, especially suitable for large buildings currently covered by both WiFi wireless LAN and fourth-generation wireless cellular network LTE femtocells. 2. Background technology [0002] Since the development of WiFi wireless local area network WLAN technology, it has been commercialized for more than ten years. The technology has developed from the original 802.11b to today's 802.11n. The transmission bandwidth has also increased from the highest 11Mbps to the current highest 600Mbps. The next step will be higher transmission The speed of ...

Problems solved by technology

[0005] In contrast, LTE technology is based on the third-generation wireless cellular technology, and its base station networking method is relatively mature. On the one hand, they have undergone long-term standardization and are more advanced than WLAN technology. Since WLAN is originally designed for families or small offices, its base station networking method is still gradually developing and improving. Recently, the 802.11 International Standardization Organization is also Carry out standardization work in this area, but generally speaking, the products of various equipment providers still lack the ability to interoperate and interconnect
