摘要： An apparatus for collision resolution among home networking stations using carrier sense. More specifically, an apparatus for collision resolution among home networking stations using Media Access Control (MAC) in the HomePNA 2.0 specification for constructing home networks is provided. The apparatus provides collision resolution to a larger number of stations than the number of stations protected by the HomePNA specification. In addition, the apparatus prevents the generation of errors caused by incorrect calculation of the number of back-off signals in the case of a carrier sense signal.

摘要： A network connection method for an asynchronous mobile terminal is provided for reducing connection latency and power consumption. A network connection method for an asynchronous mobile terminal includes displaying a list of operators identified by scanning frequencies in a manual network selection mode, acquiring, when one of the operators is selected from the list, synchronization through a frequency of the selected operator, and connecting to a network through the frequency for receiving a service. The network connection method enables a mobile terminal to select an operator network through a single frequency scanning process unlike the convention method which performs frequency scanning twice, thereby reducing connection latency and power consumption of the mobile terminal.
