Embodiment 1

[0035] image 3 It is a flow chart of the method for fusion of WLAN and 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 the authentication is passed, 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 process, the BBU of the wireless cellular network is used to complete the authentication of the core network to the WLAN terminal and after the authentication is passed, the ...

Embodiment 2

[0052] This embodiment can be used as a preferred embodiment of the first embodiment. In this embodiment, at the access layer, the WLAN AP and the BBU (Base Band Unit) are directly integrated. The WLAN AP 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 upwards, the network elements and transmission systems of the existing cellular network are completely reused, so the integration cost is very low.

[0053] In the integration process of the BBU in this embodiment, in addition to providing traditional wireless base station functions, it also needs to complete the following functions:

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

[0055] 2. In the authentication process of WLAN UE accessing the cellular network, the BBU acts as a...

Embodiment 3

[0080] Figure 7 It is a flowchart of a method for fusion of WLAN and 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 passes the authentication of 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 integration process applies the network elements in the cellular network (such as BBU and gateway equipment), the above integration process goes deep into the cellular network, enabling the two networks to achieve deep integratio...

Abstract

The invention provides a method and a device for integrating a wireless local area network (WLAN) and a wireless cellular network. The method comprises the followings steps: a baseband basic unit (BBU) of the wireless cellular network forwards authentication request information from a WLAN terminal to a core network of the wireless cellular network; the BBU forwards the authentication respond information from the core network to the WLAN terminal to complete the authentication of the core network to the WLAN terminal; and after the authentication is passed, the BBU establishes a channel for the WLAN terminal to access the core network so as to enable the WLAN terminal to access the core network. The method and the device, provided by the invention solve the problems that the WLAN and the wireless cellular network can not be completely integrated, and the cost of the integrating scheme of the WLAN and the wireless cellular network are higher in the correlation techniques, and realize the effects that the WLAN and the wireless cellular network can be completely integrated, and the integrating costs of the two networks can be lowered, thereby realizing the effect that the WLAN can be quickly deployed on an existing cellular network.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular, to a method and device for fusion of a wireless local area network (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 an extension of the fixed network in the wireless field to a certain extent. Wireless technology is used in the message access part After the message is accessed, the wireless local area network access point (Wireless Local Area Network Access Point, referred to as WLAN AP) converts the wireless message into a wired message form, and transmits the wired message in the wired network. The cellular network is a traditional 2G / 3G / 4G network constructed by various operators. The cellular network was originally designed for voice applications. With the develo...
