Because of its important practicality and NP-hard in mathematics, the reasonable allocation of HSDPA wireless access resource gets highly attentions by the wireless mobile telecommunication academia and application researchers. By the now the present research is quite limited, and the modeling, mechanism design and applications are still in primary research phase. So much need being developed and researched.Basing on the current HSDPA access technology, we provided HSDPA access technology basing on Nash competition theory in order to adapt the future trend of wireless resource control and allocation in the new mobile telecommunication systems.According to different aspects of wireless resource management, the research of HSDPA wireless access resource control and allocation could be subdivided into several sub research topics: HSDPA services bearing and Stackelberg switch model, Fast Cell Scheduling (FCS) mechanism, public channel utilization, multimedia services share cooperation, MBMS subgroups access competition and et al. Firstly we discussed the current problems existed, the solving plan and unsolved difficulty. Then we investigate multiply individual access consumers and subgroups, Node B and the multimedia services differentia access mechanisms. Traditional wireless access technology is mainly based on network providers. But with the rapid development of wireless access technology, the multimedia wireless broadband services appear new characteristics such as diversity, grading, small subgroups, individuation and so on. Because of its localization, the traditional simple centralize wireless access control model is difficult to adapt to different targets from different partners and multimedia services. It becomes the cut-in and starts point of the paper to set up new wireless resource access control and allocation strategies.Above all, some special researches in this paper are listed as follows:We analysis the complex system method and fundamental in Nash competition theory. And the application characteristic such as Nash competition clash, optimize and equilibrium are abstracted during the analysis of different wireless access application levels. The key point of Nash competition in HSDPA wireless access technology is how to modeling, analysis and computing. The model parameters are adjusted independently with few interactive signals, so it isn't mainly based on the control of core network and upper levels. And the strategies' response feedback time is little which helps the balance of the whole and resource allocation optimizes, and improves the efficiency of wireless resource utilization.According to Nash non cooperation competition based on the wireless resource access and control of HSDPA, services bearing and Stackelberg switch model over HSDPA, Fast Cell Scheduling (FCS) mechanism, public channel utilization are studied.During the research of HSDPA services bearing and Stackelberg switch model, from the point of whole system, we broke through the traditional switch strategy research localization mainly focused on access consumer and different access priorities through the research of the decision making sets of switch conflict among cells. We attempted to analysis the cells' services bearing capacity, related limiting factors, the switch state transfer, limited and unlimited repeat strategy compare during the research process of Stackelberg switch model. Then, through two periods of pure strategy Nash closed loop equilibrium, sub game perfect results are achieved.During the research of Fast Cell Scheduling (FCS) mechanism, A more impartial FCS negotiation mechanism based on consumers' apperceive is established. Based on the asymmetry Nash competition equilibrium exclusive result, provided with best matching arithmetic of FCS activation set by roam consumers, we focused on the distributing utility function constringency negotiation process during the wireless resource interactive negotiation among the neighbor, aim switch cell set and the original roaming consumer's cells. It not only considers the above competitors but also sets up the services continuous time and switch partial influence on the negotiation mechanism.During the research of the public channel utilization, basing on its distribution type, mobile ramble consumers and network's public common channels utilizations are subdivided. Provided with the share strategy under Nash compete balance, the public common channels utilizations analyze model basing on the maximum of whole utility is thus established. It also helps to the next generation of telecommunication systems design.Because of the lack of share mechanism among the wireless multimedia broadband consumers, the data is isolated with each other which are bottle neck of wireless broadband multimedia services. With the establishment of MBMS logic share channels and services quality negotiation mechanism, Shapley Nucleolus's super allocation based on Harsanyi model is provided. Through minimum ratio and non separable gap (NSCG) methods, we established multi dimension related targets of three typical wireless multimedia data services by Raiffa arbitrament.Under constant and multi grades access thresholds, some innovation is adopted in the research of MBMS access performance to avoid the individuals' performance influence. Basing on the mobile multimedia broadband services access consumers' share characteristic, the divided and independent access share mechanism is constructed. In order to relieve wireless resource and signal consumption and the asymmetry conflict, sub MBMS group under the constant and multi grades access thresholds under short-term and long-term targets are also discussed with certain agility which also helps the design and realize of new MBMS subgroup competition access strategy.At last, basing on measurable Quality of Experience (Q&E) induced from the reality, we combined the research with network bearing and automatic dynamic adaptive code technology. With system view, end to end performance scale system is brought forward to form the synthetically evaluation model basing on blurry stratification method of wireless multimedia services, which finely ensures the wireless multimedia broadband services consumers' experience, optimizes resource utilization to guarantee the application quality.Although there are some innovations researches are studied in this paper, the wireless multimedia broadband services develop day by day. So it is necessary for us to develop the useful and discard the useless during the deeper research of the complex Nash competition theory in the future.
