The present invention relates to a policy resolution method and system, access network and terminal device for enabling modular network-assisted policy resolution, wherein the policy resolution is divided into separate stages each handling specific types of trigger events and performing specific types of policy actions. The separate stages are processed in a chronological order during a policy resolution round, and trigger events which occur during a policy resolution round are frozen until the start of the next policy resolution round. Thereby, modular policy resolution with reduced delays and oscillations can be achieved. Moreover, policy processing can be divided into a policy decision point functions in the network and a policy enforcement point function in the network or terminal device, so that terminal resources used for policy resolution can be saved.

The present invention relates to a route choice method of a mobile ad-hoc network based on bandwidth constraint and minimum load, which includes three steps. Firstly, when a node needs to transmit services to another node, the node broadcasts routing request packets; secondly, when receiving a routing request message, an intermediate node compares the addresses of the intermediate node and the destination node; thirdly, when receiving the routing request from the source node, the destination node checks whether the current time is less than the time spent in receiving the routing request within the specified time. In a mobile ad-hoc network, the bandwidth resource is hard to determine due to the dynamic change of topological structures, the energy of the heavily loaded nodes in a network is rapidly depleted due to the unbalanced load distribution, and as a result the connectivity of the network is rapidly weakened, which finally shortens the total survival time of the network; the present invention resolves the problem. The present invention is compared with the existing AODV protocol by using the NS2 simulation tool, and the simulation results show that the BLLM excels the AODV in terms of packet delivery rate, packet loss rate, throughput, etc.
