摘要： The disclosure generally relates to service-tier-based regulation of reverse-link activity at an access terminal operating in a wireless access network. An exemplary method involves (a) receiving one or more reverse activity bits from a wireless access network; (b) based 5 at least in part on the received reverse activity bits, determining a Quick Reverse Activity Bit (QRAB) and/or a Filtered Reverse Activity Bit (FRAB); (c) applying a first service-tier filter to the determined QRAB, wherein the first service-tier filter corresponds to a service tier for which the access terminal is authorized; and (d) based at least in part on the service-tier filtered QRAB, determining an adjustment to reverse-link activity of the access terminal. The method may further involve applying a second service-tier filter to the determined FRAB and using the service-tier filtered QRAB in determining the adjustment to reverse-link activity.

摘要： A mobile station receives forward link signals and transmits reverse link signals for a communication session conducted via a wireless network. A controller maintains a reverse-active set that defines which sectors of the wireless network are used to receive the reverse link signals. When the mobile station transmits a request signal requesting the communication session, the controller may create the reverse-active set to include the sector that received the request signal with the highest signal strength. During the communication session, the signal strengths of the reverse link signals may be monitored in each of a plurality of sectors to obtain reverse-link signal strengths. The controller may maintain the reverse-active set based on the reverse-link signal strengths, adding sectors that report reverse-link signal strengths greater than an add threshold and dropping sectors that report reverse-link signal strengths less than a drop threshold.

摘要： Methods and systems for triggering the delivery of a message waiting indicator (MWI) are introduced. In a wireless communication network, a radio access network (RAN) determines that a wireless communication device (WCD), such as a mobile phone, has missed an incoming call, and responsively: (i) routes the incoming call to a message storage system to enable an originator of the call to leave a message for a user of the WCD, (ii) waits a period of time after routing the incoming call to the message storage system, and (iii) then generates and transmits a message waiting query to the message storage system without prompting from the WCD. In response to the message waiting query, the message storage system may transmit a signal indicative of the message to the RAN. Responsively, the RAN may then transmit to the WCD a message waiting indication (MWI) indicative of the message, for presentation of the MWI to the user of the WCD.

摘要： Methods and systems are disclosed that support the aggregation of acknowledgement messages and control messages. Advantageously, acknowledgement and negative acknowledgement indications for multiple client nodes are combined into a single aggregated message which is broadcast or multicast to the multiple client nodes. Based on unique identifiers assigned to each client node, client nodes are grouped such that the aggregated acknowledgement messages can be efficiently encoded to conserve both network capacity when they are transmitted, as well as processing capacity when they are parsed by the client nodes. If code division multiple access (CDMA) technology is used, the aggregated acknowledgment message can be transmitted without CDMA spreading to effectively broadcast or multicast it to multiple client nodes. A similar technique can be employed for the efficient broadcast or multicast of aggregated control messages.

摘要： Systems and methods for adjusting the power control settings in a wireless communication network are provided. In one embodiment, a base station determines a target access terminal's use of service so far in a billing period, wherein the target access terminal is located in a sector of the wireless communication network. The base station then determines whether the target access terminal's use of service is above a threshold value. Responsive to the base station determining that the target access terminal's use of service is above the threshold value, the base station adjusts a power control setting of one or more other access terminals located in the sector of the wireless communication network.

摘要： Disclosed in this document is an improved mechanism for notifying mobile stations that they should not seek to initiate a communication in a given wireless coverage area. The solution is to use a specially designated PN-offset as the indicator that a problem situation exists in the coverage area and that a mobile station should not seek to initiate communication in the coverage area. When a RAN detects a problem condition in a coverage area, the RAN changes the PN-offset of the coverage area to be a reserved PN-offset, and mobile stations are programmed to not seek service on any reserved PN-offset. Advantageously, the process helps stop mobile stations from operating in a problem coverage area without requiring the mobile stations to first lock onto the PN-offset of the coverage area and to then receive some sort of overhead message directing the mobile stations to not operate in the coverage area.
