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： Techniques for reducing the time required for frequency scan in acquisition are disclosed. In one aspect, received power measurements are made at one or more of the possible carrier frequencies and system search is performed on one or more of those frequencies when the power measurement exceeds a threshold. In another aspect, the power is measured at one or more frequencies in a band of frequencies surrounding a frequency at which the measured power exceeded a threshold. If the measured power at one or more of the frequencies in the band exceeds a second threshold, a system search is performed at one or more of those frequencies. In yet another aspect, frequencies meeting certain criteria are sorted in order of measured power prior to system search or further power measurement, and subsequent processing is performed in order of descending measured power. Various other aspects are also presented. These aspects have the benefit of reducing acquisition time, which results in faster system access and allows for more efficient use of system resources.

摘要： This disclosure describes techniques for efficiently handling emergency calls in a wireless communication system. The techniques are executed in a wireless communication device (WCD) that is interoperable between radio access technologies (RATs). For example, the WCD may support interoperability between the Global System for Mobile Communications (GSM) and the Universal Terrestrial Radio Access Network (UTRAN). Typically, the emergency call is redirected to another RAT or frequency following an unsuccessful emergency call. However, instead of searching only suitable cells on which to place the emergency call, a WCD that implements the described techniques searches acceptable cells of any public land mobile network and attempts to place the emergency call on the cell with the highest power. By placing the emergency call on the cell with the highest power, the techniques reduce delay in placing emergency calls by reducing the number of attempts required before successfully placing the emergency call.

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： Techniques to efficiently search for wireless networks while minimizing page loss are described. An available search time that excludes paging periods is determined. A search for cells in wireless networks is performed during the available search time. Pertinent information is obtained for cells acquired during the search. The pertinent information may be dependent on the type of search being performed. For a manual search to find detectable wireless networks, the pertinent information for each acquired cell may be network identifier information. For an automatic search to find higher priority wireless networks, the pertinent information for each acquired cell in a higher priority wireless network may be system information used to select that cell. The search may be suspended prior to a paging period. State information for the search may be saved prior to suspending the search. The search may be resumed using the saved state information at the end of the paging period.

摘要： Techniques for searching for wireless networks are described. In one scheme, a user equipment (UE) performs a manual search for detectable wireless networks while operating in a connected mode. The UE operates in the connected mode for communication with a wireless network and receives a request to search for detectable wireless networks. The UE performs a search for detectable wireless networks while operating in the connected mode, e.g., as background task during DRX time. In another scheme, the UE retains a search request received in an active state and performs a search at a later time after transitioning to an idle state. In yet another scheme, the UE efficiently handles a search across state transitions. The UE may cancel, suspend, resume, or continue the search after each transition from one state to another state based on the type of each state.
