Problems solved by technology
In order to give full play to the advantages of heterogeneous network integration, it is necessary to do a good job in heterogeneous wireless network architecture design, network selection and access mechanism, network switching, and load balancing. This is also the current research focus of heterogeneous network integration. Therefore, the existing handover technology cannot monitor the network parameters of the entire wireless network, so that the optimal network cannot be determined

The invention discloses a method for service switch between a wireless Mesh network and a cellular network. The method includes upward vertical handover and downward vertical handover; a subscriber terminal asks a control center CP for handover, the parameters of a control center network are sent to the subscriber terminal to select a network; a handshake protocol is established among the cellular network, the subscriber terminal and the wireless Mesh network to enter a switch process, so that service continuity is guaranteed and service interruption is avoided in the upward vertical handover and downward vertical handover processes of the subscriber terminal, the utilization rate of radio resources of a whole system is effectively improved, the network capacity is increased, and the network overload is avoided.
Description
technical field [0001] The invention relates to the technical field of wireless communication, and more specifically relates to a method for service switching between a wireless Mesh network and a cellular network. Background technique [0002] With the globalization of the telecommunication industry and the rapid development of the Internet, various wireless network technologies are gradually evolving towards seamlessly integrated mobile wireless Internet. The future wireless mobile communication system will be a heterogeneous network composed of various radio access networks (Radio Access Network, RAN). In a heterogeneous wireless network, users can choose to access the most suitable wireless access system at any time according to factors such as business needs and network status, so as to meet the flexible and changeable personalized service needs of users. In addition, through reasonable wireless resource management, the infrastructure and frequency resources of various...
