Abstract: Methods, devices and computer program products are disclosed that allow for wireless communication devices to operate more robustly in the slotted mode of operation in the event of network system loss. Specifically, present aspects require the wireless device to move to or remain in the slotted mode of operation as opposed to immediately entering into a system determination/acquisition mode upon failing to acquire an active set pilot during a slotted wake-up. By moving to the slotted mode of operation or providing for additional slotted-wake-ups, a number of attempts at acquiring the active set pilot can be performed before declaring the system as lost, thereby allowing for fading channel conditions to prevail without the need to re-acquire the lost system or otherwise acquire another system. Since the performance of the slotted mode is less power intensive than acquiring or re-acquiring a system, a substantial power savings is realized.

Abstract: One aspect of the invention provides a system, apparatus and method that allow a wireless communication device to intelligently search for and select a communication cell based on a system identifier (SID) and network identifier (NID) order of preference rather than just pilot signal strength. Generally, a mobile device scans a frequency channel associated with the highest preferred SID/NID for pilot signals at different PN offsets. The cell associated with the strongest pilot signal detected is queried to determine whether it belongs to the SID/NID sought. If the selected PN offset belongs to a cell associated with the SID/NID sought then it is used for communications. Otherwise, the SID/NID identification process is repeated for the next strongest PN offset detected on the same frequency channel. If no pilot signals meeting these criteria are found in the frequency channel, the next highest preferred SID/NID is selected and the process is repeated.

Abstract: A network operator identifier is used to uniquely identify each network operator to support international roaming. The network operator identifier includes (1) a Mobile Country Code (MCC) that identifies the country in which a network operator belongs and (2) a Network Operator Code (NOC), which may be a Mobile Network Code (MNC), that distinguishes network operators within a given MCC. Each network operator is assigned a unique combination of MCC and NOC that distinctly identifies the network operator, and the network operator identifier can be stored in a single entry in a preferred roaming list. The base stations of each network operator broadcast the network operator identifier in signaling messages. A mobile station receives a signaling message from a base station, obtains the network operator identifier, searches its preferred roaming list for an entry with the network operator identifier, and determines whether or not the current CDMA network is accessible.

Abstract: Techniques to efficiently search for a WLAN are described. A terminal receives country information from a wireless wide area network (WWAN), which may be a cellular network or a broadcast network. This country information may be a Mobile Country Code (MCC) that is broadcast by the WWAN. The MCC identifies the country in which the WWAN is deployed. The terminal then performs active scan for a WLAN based on the country information received from the WWAN. For the active scan, the terminal determines a frequency channel and a transmit power level based on the country information. The terminal then transmits a probe request on the frequency channel and at the transmit power level determined based on the country information. The terminal may perform passive scan and/or active scan in accordance with a scan setting.

Abstract: Techniques for efficient storage and retrieval of Preferred Roaming Lists are disclosed. In one aspect, PRL entries are stored in two tables. One table contains records that are common to two or more PRL entries. Another table stores any information that is unique to a PRL entry, as well as an indicator of which common record is associated with it. The common record is concatenated with the unique information to generate the uncompressed PRL entry. Various other aspects of the invention are also presented. These aspects have the benefit of reducing the memory requirements for storing a PRL. In addition, time required to download the compressed PRL is reduced.

Abstract: A roaming emulator provides a tool for emulating system determination for monitoring the operation of a wireless communication device (WCD) during system determination. A signal monitoring program and service selection protocol are stored, and a signal emulation module provides a signal emulation output in accordance with a predetermined set of data. A processing module performs a simulation of a service selection procedure based on the service selection protocol and performed in accordance with the signal monitoring program and the signal emulation output. A result of the service selection is provided by an output module. The emulator can provide emulated system scanning based on geographical or market location, and can emulate scenarios when channels from neighboring systems or markets “bleed” into the RF environment of the WCD.

Abstract: Techniques for performing system selection and acquisition are described. In one design, a terminal may obtain at least one system record for at least one system utilizing orthogonal frequency division multiplexing (OFDM) or single-carrier frequency division multiplexing (SC-FDM). Each system record may include system identification information for an associated system and an index for an associated acquisition record. The terminal may also obtain at least one acquisition record for the at least one system. Each acquisition record may include at least one value for at least one configurable system parameter, e.g., FFT size, cyclic prefix length, number of guard subcarriers, etc. The terminal may perform acquisition for the at least one system in accordance with the at least one system record and the at least one acquisition record. The system and acquisition records may be stored in a Preferred Roaming List (PRL) or a Most Recently Used (MRU) list.
