The present invention relates to a method and apparatus for controlling a connection transfer in a cellular network having at least two systems, such as a GSM system and a WCDMA system. Based on a load determination, a service-based inter-system or inter-frequency handover of the connection to another system or to another carrier of the same system is initiated if the determined is below a threshold and service priorities are indicating it. If it exceeds the threshold, an additional load-based inter-system or inter-frequency handover can be initiated. If the load of the target cell is not known, a load estimation based on a learning process can be used to derive a probability of success of an interfrequency or inter-system hand-over, which may be used for deciding on the initiation of the inter-system hand-over. The learning process may be performed by evaluating preceding interfrequency or inter-system handovers to the target cell or preceding interfrequency or inter-system handovers from the target cell. Thereby, users can be shared between different radio access technologies or systems or between different carriers of one system to thereby improve network capacity and quality of service for both systems and carriers. Furthermore, unnecessary inter-system handovers can be prevented in case the load of the target cell of the other system is not known.

The invention is a handover determining method in mobile communication system, comprising: 1) network side sends link loss measurement control command to user terminal to appoint the parameters the user terminal needs to measure; 2) the user terminal receives the control common and measures, and reports the measured results in an event triggered mode or periodically, where the measured results include the preset number of larger link loss difference integration values or link loss difference integration values larger than first threshold value, selected from the adjacent cells which require measuring; 3) the network side selects a target cell of local terminal from the reported adjacent cells and switches terminal connected wireless link from service cell to target cell. And it can switchterminal a cell which can provide better link condition.

The invention includes a driving circuit module, a receiving circuit module, a main transmission line for connecting the driving circuit module and the receiving circuit module, and a micro strip structure connected between the driving circuit module and the receiving circuit module. The driving circuit module includes a driving circuit and a first transmission branch line used for transmitting signal output from driving circuit to the main transmission line. The receiving circuit module includes a receiving circuit and a second transmission branch line use for receiving signals from main transmission line and sending it to receiving circuit module. The micro strip structure functions like a capacitor. When the signal state in driving circuit module switches too fast, the micro strip structure is used to substitute for capacitor to decreases switching rate of signal.

A method for selecting a high-speed mobile user relay node in the coordination communication of a cellular system relates to a selection method of a relay node, which solves the problems that the selection success rate of a relay user is low, after the selection is realized, the duration is short, and the frequent handover is required in the selection method of the high-speed mobile user relay node currently. The method comprises the following steps: a base station groups each node entering a cell; a source node sends out a coordination communication request; the base station sends out communicable confirmation information to the source node, and the node which is positioned in the same group as the source node sends out a request which can carry out the coordination communication and thechannel quality between the node and the source node to the base station simultaneously; the base station selects the node with the best channel quality as the relay node, and allocates a relay channel; and when the channel quality between the relay node and the source node or the channel quality between the relay node and the base station is lower than the threshold value, the base station re-selects a new relay node, and is used for stopping the relay through sending out an instruction or responding a request directly communicating with the source node.

The present invention claims to protect a vertical handover method for cognitive heterogeneous wireless networks. In cognitive heterogeneous wireless networks, cognitive radio networks use spectrum opportunistically, which makes the problem of frequent handover more prominent. Aiming at this problem, this paper proposes a network selection algorithm based on grey relational analysis and bipartite maximum matching. On the user side, the grey relational analysis method is used to rank cognitive heterogeneous wireless networks; on the network side, the maximum matching algorithm of bipartite graph is used to achieve the optimal matching between users and the network. Simulation results show that the algorithm can effectively control frequent handovers, improve network throughput and user service quality, and achieve load balancing.

A method and a system for expanding coverage of cells with same frequency and the same pseudo random noise are provided. The method includes the following steps. One or multiple virtual cells are set in networking coverage. Every virtual cell includes one or multiple element cells with the same carrier frequency and the same pseudo random noise value. The handoff relation between the element cells in every virtual cell is set to be softer handoff relation. The base station transceiver processes the signals belonging to the different element cells in the same virtual cell uniformly. The method and the system can decrease dropped call rate and increase system capacity.

The invention provides a user-centered multi-connection mobility design method based on an anchor point. In a user-centered network, multiple APs serve users simultaneously through multi-connection technology, which is called active set. The AP with the largest backhaul capacity is responsible for the control plane as an AP C, and is responsible for the user plane together with other APs. AP C updates the active set AP according to DL-RSS to ensure that the user is always at the center of the active set. When there is a new AP that provides stronger RSS than any service AP, if AP C is unchanged, then AP C controls the switch of user plane. If the AP C leaves the active set, the AP with the largest backhaul capacity is selected from the active set as the target AP C, and the switch of the control plane occurs. Compared with traditional dense network handoff design, anchor-based user-centered multi-connection mobility performance is significantly improved, and the control plane handoff probability is reduced by at least 30%.
