Embodiment 1

[0035] image 3 It is a flowchart of a method for integrating a WLAN and a wireless cellular network according to Embodiment 1 of the present invention. Such as image 3 As shown, the method includes:

[0036] Step S302, the baseband processing unit BBU of the wireless cellular network forwards the authentication request information from the WLAN terminal to the core network of the wireless cellular network;

[0037] Step S304, the BBU forwards the authentication response information from the core network to the WLAN terminal, so as to complete the authentication of the WLAN terminal by the core network;

[0038] Step S306, after passing the authentication, the BBU establishes a channel for the WLAN terminal to access the core network, so that the WLAN terminal accesses the core network.

[0039] Through the above processing process, since the BBU of the wireless cellular network is used to complete the authentication of the WLAN terminal by the core network and after the a...

Embodiment 2

[0052] This embodiment can be used as a preferred embodiment of the above-mentioned embodiment 1. In this embodiment, at the access layer, the WLANAP is directly integrated with the BBU (Base BandUnit). The WLANAP can be built into the BBU, or a general WLAN AP can be used to directly connect to the BBU through a network port. From the access layer up, all network elements and transmission systems of the existing cellular network are fully reused, so the integration cost is very low.

[0053] In this embodiment, during the fusion process, the BBU needs to complete the following functions in addition to providing traditional wireless base station functions:

[0054] 1. Integrate a functional module similar to WLAN Access Controller to realize functions such as access authentication of WLAN AP, version upgrade, keep alive between WLAN UE and BBU, and DHCP address allocation.

[0055] 2. During the authentication process of the WLAN UE accessing the cellular network, the BBU act...

Embodiment 3

[0080] Figure 7 It is a flowchart of a method for integrating a WLAN and a wireless cellular network according to Embodiment 3 of the present invention. Such as Figure 7 As shown, the method includes:

[0081] Step S702, after determining that the WLAN terminal accessing the core network of the wireless cellular network has not been authenticated, the baseband processing unit BBU forwards the received authentication information of the WLAN terminal to the gateway device of the wireless cellular network;

[0082] Step S704, after the authentication information is authenticated by the gateway device, the BBU establishes a channel for the WLAN terminal to access the core network, so that the WLAN terminal accesses the core network.

[0083] Since the above-mentioned fusion process applies the network elements (such as BBU and gateway equipment) in the cellular network, the above-mentioned fusion process goes deep into the interior of the cellular network, so that the two netw...

Abstract

The present invention provides a method and device for integrating a wireless local area network and a wireless cellular network, wherein the method includes: the baseband processing unit BBU of the wireless cellular network forwards the authentication request information from the WLAN terminal to the core network of the wireless cellular network ; The BBU forwards the authentication response information from the core network to the WLAN terminal to complete the authentication of the WLAN terminal by the core network; after the authentication is passed, the BBU establishes the The WLAN terminal accesses the channel of the core network, so that the WLAN terminal accesses the core network. The present invention solves the problems in related technologies that the partial fusion of WLAN and cellular network is not fully integrated, and the cost of the fusion scheme of WLAN and cellular network is relatively high, thereby achieving the complete integration of WLAN and cellular network and reducing the fusion between the two networks The effect of cost, so as to realize the rapid deployment of WLAN on the existing cellular network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for integrating a wireless local area network (WLAN for short) and a wireless cellular network. Background technique [0002] WLAN is a technology that uses radio waves as a transmission medium to provide users with network services within a certain local area. WLAN technology is to some extent an extension of the fixed network in the wireless field. Wireless technology is used in the message access part. , after the message is received, the wireless local area network access point (Wireless Local Area Network Access Point, WLAN AP for short) converts the wireless message into a wired message, and transmits the wired message in the wired network. The cellular network is a traditional 2G / 3G / 4G network built by various operators. The cellular network was originally designed for voice applications. With the development of technology, the cellular network is incr...
