Problems solved by technology
The main defect of the current technical solution is that the WLAN and the TD cellular network serve users independently. During the process of using the network, the user cannot work on the two networks at the same time, and can only choose one of them.
This causes one of the networks to be congested because it is busy, while the other network is empty and wastes wireless resources.

Embodiment Construction
[0047] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0048] like figure 1 , figure 2 , image 3 As shown in the heterogeneous network cooperative communication protocol method, the reselection of the route must be realized in the PDSN part;
[0049] S1, the data is sent via MN-BS-PCF-PDSN;
[0050] S2, the data reply is from CN-PDSN-PDIF-AP-MN;
[0051] The implementation of the protocol algorithm is divided into four steps,
[0052] The first step is to load network information, mainly to select routes and load routing information in the BOCP frame header;
[0053] The second step is to select a possible path in the routing table according to the information contained in the BOCP frame header;
[0054] The third step is to add the selected path to the BOCP frame header;
[0055] The fo...

The invention discloses a collaborative communication protocol method of a heterogeneous network, and relates to the mobile Internet. The collaborative communication protocol method is used for solving the main defect in the current technical scheme that independent service users of WLAN and TD cellular network cannot work on the two networks at the same time when using the networks and can only select one of the networks. Reselection of routing is achieved on a PDSN part; S1, data transmission is carried on along MN-BS-PCF-PDSN; and S2 data reply is carried on along CN-PDSN-PDIF-APMN. The technical scheme provides the design of a new algorithm to achieve collaborative communication of the WLAN and TD cellular networks, as shown in Fig.1. The new algorithm makes use of the two networks to serve the users at the same time, and realizes the cooperative communication between the two networks, that is, the request of the data is sent through the TD cellular network, and the reply is transmitted through the WLAN.
Description
technical field [0001] The invention relates to a mobile internet network, specifically, a collaborative communication protocol method for a heterogeneous network. Background technique [0002] The TD-SCDMA (hereinafter referred to as TD) standard is a 3G standard formulated by my country with independent intellectual property rights. It was proposed to the ITU on June 30, 1998 by the Telecommunication Science and Technology Research Institute (Datang Telecom), the former Ministry of Posts and Telecommunications of China. TD has abundant frequency resources, with a single carrier bandwidth of 1.6MHz, a core frequency band of 55MHz, 33 core frequency points, a supplementary frequency band of 100MHz, and 62 supplementary frequency points. It has a flexible networking mode, which can not only be used for the construction of macro cellular networks, but also especially suitable for building micro-cellular or pico-cellular networks in high-density user areas in cities and suburbs...
