    • Techniques for efficiently performing network selection using information stored at a terminal are described herein. The terminal may store coverage information for previously detected wireless networks, cell information for previously detected cells in wireless networks, usage information for previously accessed wireless networks, availability information for previously detected wireless networks, almanac information for cells in wireless networks (e.g., information on cells available at different locations and information for acquiring the cells), and/or other information that may be useful for network selection. The terminal may select a wireless network to attempt acquisition based on the stored coverage information and its current location, the stored cell information and information for the current location (e.g., an identity of a cell detected at the current location), the stored usage information, the stored availability information, and/or the stored almanac information.
    • 这里描述了使用存储在终端处的信息来有效地执行网络选择的技术。 终端可以存储先前检测到的无线网络的覆盖信息,无线网络中先前检测到的小区的小区信息,用于先前访问的无线网络的使用信息,用于先前检测到的无线网络的可用性信息,无线网络中的小区的年历信息(例如, 在不同位置可用的小区和用于获取小区的信息)和/或可能对网络选择有用的其他信息。 终端可以基于存储的覆盖信息及其当前位置,存储的小区信息和当前位置的信息(例如,在当前位置检测到的小区的身份)来选择无线网络来尝试获取所存储的使用信息 ,存储的可用性信息和/或存储的历书信息。

    • Methods (200) and apparatus (700) for providing an access to a first communication network (102) through a second communication network (106) by a communication device (108) are disclosed. The communication device (108) having a first identification and supporting a cellular core network signaling protocol of the first communication network (102), upon entering the second communication network, is assigned a second identification by the second communication network (106). The communication device (108) communicates with the first communication network (102) through an alternative network controller (104) utilizing the second communication network (106). Method (500) for providing an access to a preferred communication network out of a plurality of communication networks based upon a predetermined condition is also provided.

    • A method for universal mobile telephone service synchronization by a mobile station operating in a GSM dedicated mode in a wireless communication system including a mobile station sending voice signals to and receiving voice signals from a base station. A voice activity detector transmits control information indicating detection of voice activity at the mobile station, and an equalizer identifies and processes a training sequence and transmitting corresponding information for the training sequence. A physical layer interface determines whether the mobile station is utilizing discontinuous transmission mode, based on the control information from the voice activity detector, and determines whether the based station is utilizing discontinuous transmission mode, based on the correlation information from the equalizer, and universal mobile telephone service synchronization is performed in response to the mobile station and the base station utilizing discontinuous transmission mode.
