摘要： Techniques for efficiently performing system search to obtain service from a wireless system as quickly as possible are described. A terminal initially looks for service from a first (e.g., W-CDMA) system. The terminal identifies network(s) in the first system from which service was received in the past and performs acquisition on each network to look for service. If service is not found for the first system, then the terminal performs a search for a second (e.g., GSM) system. If service is found on the second system, then the terminal obtains service from the second system and avoids a frequency scan for the first system. Otherwise, the terminal performs a frequency scan for the first system using the search results for the second system. The terminal may obtain a list of RF channels detected for the second system and may omit these RF channels and possibly some other RF channels around these RF channels from the frequency scan.

摘要： Methods, devices and systems enable the dynamic updating of home public land mobile network (HPLMN) information stored on a subscriber identification module (SIM) to avoid a roaming indication, without requiring any modifications to the mobile device modem, SIM application programming interface (API), the modem software, or the mobile device operating system. A mobile device may scan available public land mobile networks (PLMNs) to identify a participating PLMN to which the mobile device may connect, and receive network values having a mobile country code (MCC) value and a mobile network code (MNC) value from the identified PLMN. The mobile device may overwrite an existing HPLMN value and/or one or more IMSI values on the SIM with the receive network values.

摘要： Methods and apparatus for controlling provisioning of a wireless communication device in a cellular network may include maintaining, at a network component, a provisioning status database comprising status information corresponding to provisioning in a home location register of one or more wireless communication devices for one or more cellular networks. In addition, the methods and apparatus may include initiating provisioning or de-provisioning of a wireless communication device for a cellular network in the home location register in response to a triggering event.

摘要： Techniques to improve searches for wireless networks are described. A terminal uses results of a search for one radio technology to reduce the search space for another search for the same radio technology or a different radio technology. In one scheme, a first search for a first radio technology (e.g., GSM) is initially performed, and search results indicating frequency channels acquired for the first radio technology are obtained. A second search for a second radio technology (e.g., W-CDMA) is performed using the results of the first search to omit frequencies from the second search. In another scheme, acquisition is performed on at least one frequency channel previously acquired for a radio technology (e.g., W-CDMA). A search for the radio technology is then performed using results of the acquisition to omit frequencies from the search.

摘要： Techniques for performing uniform out-of-service (UOOS) search to detect for wireless systems are described. The UOOS search is uniform in that sleep cycle and/or awake period are fixed. A wireless device transitions to an OOS state upon detection of OOS conditions for a radio access technology (RAT). The wireless device performs system search during the awake period of each sleep cycle while in the OOS state. The awake period may have a first fixed time duration, and the sleep cycle may have a second fixed time duration. In each awake period, the wireless device may either start a new search or resume a prior search based on saved state information if the search was not completed in a prior awake period. In each awake period, the wireless device may (i) start and complete a search for recently acquired frequency channels and systems and (ii) start or resume a search for other frequency channels and systems in one or more RATs.

摘要： The disclosure is directed to techniques for performing service signal searches with reduced power consumption when a wireless communication device is operating out of service. The techniques include placing the wireless communication device in a "deep sleep" mode when the wireless communication device is not in service. When operating in the deep sleep mode, the wireless communication device reduces power consumption by not looking for paging signals or searching for service signals. The wireless communication device then may periodically enter a wake-up period during which power consumption is increased to perform signal searches in one or more frequency bands. The wireless communication device returns to the deep sleep mode when the signal searches are unsuccessful.
