Abstract: A system and a corresponding method for controlling transmission of a non-zero supplemental channel request message, denoted SCRM, by a wireless communication device are described, wherein the system comprising means for selectively enabling transmission of a non-zero reverse supplemental channel SCRM, denoted R-SCH SCRM, wherein transmission of a non-zero R-SCH SCRM is selectively enabled based in part on a predetermined characteristic of a reverse supplemental channel, R-SCH, burst.

Abstract: To mitigate re-syncs, RLP sync control frames associated with a packet data session can be sequence numbered. A single sequence number can be assigned for an entire sync procedure associated with the initiation of a packet data session. For example, the sequence number can remains the same on all sync control frames (SYNC, SYNC/ACK, ACK) of a particular packet data session. When a sync frame is received out of order within a single sequence, it can be ignored under certain conditions. For example, if a SYNC frame with a sequence number 0 is received out of order after an ACK frame with sequence number 0 is received, the mobile station can ignore the out of order SYNC frame. Thus, an RLP re-sync is avoided due to out of order RLP sync packets.

Abstract: A method to enhance performance of a dual-mode or dual-band mobile phone includes, after the phone has initially connected to a CDMA wireless network, monitoring a level of total power received by the phone. This power level is compared to a preset threshold level. If the power level remains below the threshold level for over two seconds, the dual-mode or dual-band phone switches to an AMPS or other network retrieved from the preferred roaming list that is stored in the phone. If the power level is above the threshold, the phone moves into the idle state. Once in the idle state, both the pilot strength and Received Signal Strength Indication are monitored. If both of these levels are below respective thresholds for over eight seconds, the phone switches to another network stored in the preferred roaming list. If the mobile phone is not a dual-mode or dual-band phone, the mobile phone can perform similar measurements and switch between service provider systems compatible with the mobile phone.

Abstract: A method of creating a path list for use in finger assignments comprising clearing a list of paths (12), choosing a sector for consideration from an active set of sectors (14), establishing a searcher window around the sector for cosideration (16), and determining up to "n" local maxima stronger than a threshold value (18). If a sector under consideration is transmitting on supplemental channels(19), the method involves artificially biasing the findings of the searcher window by a predetermined value (20). The biasing value may be constant, variable or proportional to the number of supplemental channels on the base station. After the local maxima corresponding to base stations transmitting on supplemental channels have been biased (20), the path lists are created (21).

Abstract: A method and apparatus for decreasing the probability of dropping a call during a hard handoff procedure in a wireless communication system. The two primary functions of the candidate frequency (CF) search method and apparatus of the present invention are to detect the strong pilots on a candidate frequency in the area of the mobile station and to maintain adequate service quality during the CF search.

Abstract: A system for facilitating the acquisition of a most desirable wireless service for a wireless phone. The system includes a scanning mechanism for periodically scanning for a signal indicative of a wireless service having a coverage area that overlaps one or more coverage areas of other wireless services. A service acquisition mechanism acquires the wireless service or one of the other wireless services based on predetermined selection criteria and the signal. More specifically, the present invention includes a wireless phone having a first mechanism for determining if a detected system, i.e., service is associated with a coverage area that overlaps one or more coverage areas of different systems. A second mechanism compares the different systems to the detected system and selects a preferred system based on the comparison. A third mechanism acquires the preferred system. In the specific embodiment, the wireless phone includes a computer that runs software for implementing the first, second, and third mechanisms.
