Abstract: PROBLEM TO BE SOLVED: To provide a method of enhancing performance of a dual-mode or dual-band mobile phone.SOLUTION: After the mobile phone is initially connected to a CDMA wireless network, the level of total power received by the phone is monitored and this power level is compared to a preset threshold level. When the output level remains equal to or below the threshold level for two seconds or longer, the mobile phone switches to an AMPS or other network retrieved from the preferred roaming list that is stored in the phone. When the output level is above the threshold, the phone moves into the idle state and monitors both a pilot strength and a received signal strength indication. When both of these levels are equal to or below respective thresholds for eight seconds or longer, the mobile phone switches to another network stored in the preferred roaming list. When 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: PROBLEM TO BE SOLVED: To provide a method and an apparatus for scheduling reverse link transmission for a mobile station in a timely manner.
SOLUTION: A base station 101 may transmit reverse link supplemental channel scheduling information on a forward link high rate channel and a forward link low rate channel to a mobile station during a common time slot. The high rate and the low rate channels may be respectively the F-PDCH and the F-PDCCH. The base station may transmit reverse link transmission scheduling information on the low rate channel. The mobile station may schedule transmission on the reverse link channel, such as R-SCH, on the basis of the data received on the low rate channel. Since the low rate channel includes only scheduling data (16 bits) and the high rate channel may have no data (null data) at all, the base station may decide to transmit the reverse link scheduling information to the mobile station very quickly on the forward link.

Abstract: PROBLEM TO BE SOLVED: To facilitate the effective use of low frequency low power clocks for a sleep mode of a wireless communication device, even when relatively large slot cycles are defined within a slotted paging system. SOLUTION: Techniques may include reducing power in the wireless communication device for a first sleep period and then increasing power in the wireless communication device for an intermediate wake period after the first sleep period to estimate an error of the sleep clock. The method may further include reducing power in the wireless communication device for a second sleep period after the intermediate wake period. The intermediate wake mode implemented during the intermediate period can be used to estimate the error of the sleep clock without performing one or more tasks associated with an awake mode, such as demodulation.

Abstract: A system and method for detecting discontinuous transmission (DTX) frames. The inventive method includes the steps of receiving data transmitted in a plurality of frames; classifying each of the frames; analyzing the classification of a number of successive frames of the received data and providing a metric with respect thereto; and determining, in response to the metric, if a frame is a discontinuous frame. In the illustrative embodiment, the step of classifying includes the step of error checking the frames using a cyclic redundancy check (CRC) error checking protocol. The received frames are classified as good frames (G), erasure frames (E), or discontinuous frames (D). A numerical value is assigned to each of the frames based on the classification thereof. Next, the frames are filtered to provide an output Yn=Yn-1+Xn where 'n' is a frame number, Yn is the filter output for a given frame n, Yn-1 is the filter output for a previous frame, and Xn is a stream of input frames. A threshold is set for the output Yn to facilitate the detection of discontinuous frames. That is, a detection of a discontinuous transmission frame is indicated when a frame is classified as an 'erasure' and the filter output exceeds the threshold. On the detection of a discontinuous frame, the classification of the frame is changed from 'erasure' to 'discontinuous'. By reclassifying improperly classified erasure frames, the mobile receiver is inhibited from requesting retransmission of the frames or a change in the transmit power level. Consequently, network throughput and capacity are optimized and system power is conserved.

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 (304) a level of total power received by the phone. This power level is compared (304) to a preset threshold level (C). If the power level remains below the threshold level for over two seconds (308, 312), the dual-mode or dual-band phone switches (314) 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 (402). Once in the idle state, both the pilot strength and Received Signal Strength Indication are monitored (404). If both of these levels are below respective thresholds for over eight seconds (408, 412), the phone switches (414) 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: Techniques for minimizing call setup latency are disclosed. In one aspect, multiple signaling messages are encapsulated and sent as a single message thus reducing the total delay incurred by sequential transmission. In one embodiment, an encapsulation message includes a field indicating the number of messages encapsulated therein. In one example, the encapsulation is performed at a Link Access Control (LAC) layer. Alternate embodiments may perform encapsulation at an alternate layer.
