摘要： Methods and systems for adaptive hybrid automatic repeat request (H-ARQ) protocols are disclosed. The protocols preferably adapt to changing network conditions between a client node and an access node by omitting the transmission of certain messages when network conditions are determined to be favorable. In doing so, packets are processed faster, thus reducing communication latency as well as the memory requirements of the protocols. One scenario in which the protocols may operate is where the client node is a wireless communication device coupled to the access node via a wireless network. In such a scenario, the access node may, from time to time, measure a quality of the wireless air interface between the client node and the access node, and determine whether to transmit an acknowledgement message based on the outcome of the measurement as compared to a threshold value.

摘要： An access terminal in a coverage area of an access network may be monitoring a level of loading on the coverage area's reverse link, such as by monitoring a series of reverse activity bits sent by the access network. The access terminal may then detect new data for transmission to the access network and responsively select a reverse-link data rate based on the monitored level of loading. In this respect, the access terminal may select (a) a first data rate (e.g., a reverse-link data rate at which the access terminal last transmitted data) if the access terminal detects a low load, and (b) a second data rate (e.g., a minimum available reverse-link data rate) if the access terminal detects a high load, where the second data rate is lower than the first data rate. The access terminal may also consider its location in selecting the reverse-link data rate.

摘要： A method and system is disclosed for shifting the phase of a PN long code for access attempts by an access terminal in a wireless communication network. An access terminal may seek to acquire access from a base station that is detected by the access terminal above a threshold power level, even if the access terminal is further away from the base station than a threshold distance beyond which access is not normally granted. According to one embodiment, the access terminal will, upon determining that it is beyond the threshold distance, embed in an access request message an apparent distance that is smaller than the threshold distance, by phase-shifting a timing signal and encoding the access request message with the phase-shifted timing signal. The access terminal will then transmit the access request message on an air interface communication link to the base station.

摘要： An access network may be maintaining data indicating which of its coverage areas have a short occupancy time. The access network may then conduct a first paging of an access terminal in each coverage area in a first set of coverage areas, the first set including a subset of coverage areas having a short occupancy time. Thereafter, the access network may determine that it has not received a response to the first paging from the access terminal during a first timeout period, which is preferably shorter than a predefined paging timeout period. In response, the access network may conduct a second paging of the access terminal in only each coverage area in the subset of coverage areas (i.e., the coverage area(s) in the first set of coverage areas that have the short occupancy time).

摘要： A method and apparatus for improved idle handoff a mobile station in a wireless communication system. While idling in a particular sector of the system, the mobile station will select a target sector based on a determination that the target sector has the same number of channels as the current sector, such as the same number of paging channels and perhaps the same number of frequency channels as the current sector. The mobile station will then engage in an idle handoff from the current sector to the selected target sector. By striving to hand off to a sector that has the same number of channels, particularly the same number of paging channels, the mobile station may avoid having to hash onto a channel in the target sector and may thereby minimize the likelihood of missing a page message sent while the mobile station was busy hashing onto the channel.

摘要： A wireless communication device (WCD) may be able to acquire wireless service from preferred wireless coverage areas that are managed by the WCD's service provider. In some cases, the WCD may instead use wireless service from non-preferred wireless coverage areas of the service provider's roaming partners. In order to save roaming fees, the service provider's RAN may determine when the WCD is likely to roam to a non-preferred wireless coverage area. In response to this determination, the RAN may transmit a redirect message to the WCD, causing the WCD to switch from one preferred wireless coverage area to another preferred wireless coverage area. In some situations, the RAN may transmit such a redirect message because the WCD has reported that it has a low remaining battery life.

摘要： A method to manage a call in a communication system and an access node of the communication system are disclosed. The method includes receiving, by the communication system, a call request for a voice call from a first device to communicate with a second device, wherein the second device is a subscriber of the communication system, and transmitting, by the communication system to the first device, a first message comprising an indication that the second device is operating in a text message-only mode, when the second device is roaming and a roaming usage of the second device meets a roaming criteria. The access node may be configured to transmit to the first device the first message, when the first device requests to establish a call with the second device through the access node, the second device is roaming, and a roaming usage of the second device meets the roaming criteria.

摘要： A method and corresponding system for controlling billing for communication service. An area of coverage of a first wireless serving system is dynamically determined based on signals from one or more mobile stations served by the first wireless serving system. A determination is then made as to whether a mobile station was within the determined area of coverage of the first wireless serving system when the mobile station was being served with communication service by a second wireless serving system. And a billing rate, for billing for the communication service, is selected based at least in part on the determination.

摘要： A mobile station requests origination of a call and reports signal strength measurements of pilot signals from multiple sectors, where some of the sectors support a preferred air interface configuration (such as RC 11) and some do not. The signal strength measurements may be evaluated to determine which sectors to use for the call and whether to use RC 11 or a default air interface configuration (such as RC 3 or RC 4) for the call. Sectors that support the preferred air interface configuration may be evaluated using a first threshold, and sectors that do not support the preferred air interface configuration may be evaluated using a second threshold. The first threshold can be greater than the second threshold, in order to favor the use of sectors that support the preferred air interface configuration over sectors that do not.
