Disclosed is an apparatus and method for executing the handoff process in the wireless networks. The apparatus comprises a processor to execute an identity checking mechanism. When a wireless network station wants to move from a source AP to a destination AP, the wireless network station sends an authentication request message to the destination AP. The identity checking mechanism searches a R0KH table of the destination AP for the R0KH ID contained in the authentication request message, and determines a setting parameter for executing a handoff process. Thereby, the wireless network station may execute the handoff process. A R0KH table of an AP consists of all IDs of R0KHs that can be accessed by the AP.

A movement predicting method is disclosed. The method utilizes at least one phone communicating in and moving between neighboring cells of base stations to predict population movement in a prediction interval. Firstly, obtain the traffic volumes in the cells generated by the phone and the handover information generated by the phone moving between the cells in a day. Next, calculate the traffic volumes and the handover information to obtain a movement probability for the population moving between the cells and an average residence time that the population stays in the region of each cell in the different periods of the day. Finally, according to the data obtained, predict an appearance probability that the population appears in each region at the end point of the prediction interval.

A selection method for transmitting network packets adapted to be executed by a multiple-interface network device is provided. The multiple-interface network device includes a plurality of network interfaces. Each of the network interfaces connects to one of multiple communication networks. The selection method includes the following steps: collecting a transmission status of each of the communication networks; analyzing transmission characteristics of a predetermined number of packets of a service flow to determine a traffic pattern type of the service flow; comparing the transmission status of each of the communication networks with the transmission requirements of the traffic pattern type of the service flow to select one of the network interfaces, and using the selected network interface to transmit packets of the service flow. The service flow is constituted by packets transmitted by the network interfaces through a port and packets received by the network interfaces through the same port.
