Example Embodiment

[0019] Specific implementation mode one, combination Figure 1 to 2 To describe this embodiment in detail, the 3G / WLAN heterogeneous network access control method based on non-cooperative game resource allocation described in this embodiment includes the following steps:

[0020] Step 1. Define the coverage area AP according to the bandwidth allocated by the user i User x utility function

[0021] U a p i , x = ω log αb - - - ( 1 )

[0022] among them, Indicates that the connection x is at the AP i Coverage area utility, b means AP i Connect the bandwidth of x, ω and α are constants, and perform step 2 at the same time;

[0023] Step 2: According to the 3G / WLAN network coverage model, obtain the expression of the total network utility in the entire service area, and obtain the resource allocation plan that satisfies the maximum utility function, and perform step three;

[0030] Specific implementation manner 2. In this specific implementation manner, the specific steps of obtaining the total utility expression of the network in the entire service area and obtaining the resource allocation plan that satisfies the maximum utility function in step two are as follows:

[0031] figure 1 The architecture diagram of a hybrid heterogeneous network composed of a 3G / WLAN network. The service area of ​​the WCDMA network is a 0 ,a 1 ,...,A n , The service area of ​​TD-SCDMA network is b 0 ,b 1 ,...,B n , CDMA2000 network service area is c 0 ,c 1 ,...,C n . For the WLAN network, because there is no problem of how the bandwidth of each WLAN network AP coverage area is allocated, only the bandwidth allocation of the other three networks in each area needs to be considered. In order to ensure the fairness of the bandwidth allocated to each user in the area, bandwidth is allocated to each user in each area according to the principle of equal distribution. Accord...

Example Embodiment

[0045] Specific implementation mode 3. In this specific implementation mode, the specific steps for establishing the non-cooperative game model of wireless resources in the 3G / WLAN network environment described in step 3 to obtain the utility expressions of the WCDMA network, TD-SCDMA network and CDMA2000 network are: :

[0046] according to figure 1 The shown network coverage model establishes a non-cooperative game model of wireless resources. Because in resource allocation, the resources that each AP of the WLAN network can provide are related to the number of users, and there is no competition with WCDMA networks, TD-SCDMA networks, and CDMA2000 networks, and there is no competition between APs. Therefore, when establishing a non-cooperative game model of wireless resources in a heterogeneous network, participants only need to consider the WCDMA network, TD-SCDMA network and CDMA2000 network, without considering the WLAN sub-network. Since the final strategy adopted by the ...

Abstract

A non-cooperation game resource allocating-based 3G (the third generation telecommunication) / WLAN (wireless local area network) heterogeneous network accessing control method belongs to the technology of a wireless heterogeneous network, and solves the problems such as low network effectiveness, unbalanced resource allocation in each area and low resource utilization rate in the existing heterogeneous network resource allocating and accessing control. The method comprises the steps of establishing a 3G/WLAN non-cooperation game model to obtain an effectiveness expression of the WCDMA (wideband code division multiple access), the TD-SCDMA (time division-synchronization code division multiple access) and the CDMA (code division multiple access) 2000, solving the non-cooperation game Nash equilibrium solution of the three networks as the optimal time solution of the total network effectiveness in the whole service area and proving the uniqueness of the Nash equilibrium. The bandwidth in each covering range is obtained according to the allocating result of the CDMA, TD-SCDMA and the CDMA2000 network game sources, the rest bandwidths of the WCDMA, TD-SCDMA, the CDMA2000 and the WLAN network are computed, the accessing of a new user and the switching of the user in the network are judged and the method is suitable for the field of the wireless heterogeneous network.

Description

technical field [0001] The invention belongs to the technology of wireless heterogeneous networks, and in particular relates to a 3G / WLAN heterogeneous network access control method based on non-cooperative game resource allocation. Background technique [0002] In future wireless communication systems, heterogeneous network convergence has attracted more and more attention due to its advantages in coverage, number of users, business types of users, and quality of service. The integration of various wireless access networks such as WCDMA network, TD-SCDMA network, CDMA2000 network and WLAN network can provide users with better services. Access control is a technology for judging whether to accept user call requests. It is an important part of wireless heterogeneous network integration. A good access control strategy can help reduce network congestion and ensure service quality. The traditional access control strategy determines whether to access the user request by comparin...
