摘要:
Rate assignment circuitry (102) detects when a data transmission begins and originally assigns an Orthogonal Variable Spreading Factor (OVSF) code corresponding to low data rate. Over time, a base station controller (101) determines when an OVSF code and/or a repetition rate should be changed (i.e., data rate increased or decreased). The OVSF code and/or the repetition rate is changed in order to gradually increase the data rate, up to a maximum allowable data rate. Once data transmission ceases for a period of time the OVSF code and/or the repetition rate is changed in order to gradually decrease the data rate, down to a lowest allowable data rate.

A method for paging a mobile station where the mobile station (208-212) may be in a dormant state is described. The method begins by sending a first paging message (302) in a first zone (214) of a given area to a selected mobile station wherein the first paging message is sent at the beginning of a paging interval (300). A base station (202-206) then receives a response to the paging message when the mobile station is in the first zone. When the response to the first paging message is not received, a second paging message (306) is sent in a second zone (216) of the given area. The second paging message is sent at a first offset (308) from the sending of the first paging message wherein this first offset occurs less than one paging interval after the sending of the first page message.

A method (300) and communication device (106) capable of streamlining call setups to a wireless mobile unit (102) may include a transceiver (520) and a controller (502). In various embodiments of the invention, the controller detects (302) a modified request for a communication resource, optionally monitors (304) a communication system loading parameter, and sends (406 or 408) an assignment for a larger than anticipated allocation of the communication resource upon detecting the modified request or when the system loading parameter falls below a predetermined threshold. The controller may also receive (410) via the larger than anticipated allocation of the communication resource both an anticipated initial data transmission and an initial user data transmission in a first data transmission from the mobile wireless unit.

A method and an apparatus that includes establishing a link (106) between a first node (102) and a second node (104) in a wireless communication network (100). The method continues by setting a discontinuous receive (DRX) transmission mode cycle for the link wherein the DRX cycle includes an on duration (202) followed by an off cycle (204). The duration of the on duration on a downlink is adjusted (610) based on a function of the availability of a channel quality indicator (CQI) channel used on the link.

Disclosed is a method for providing power control using idle-mode user equipment attached to a cell in a wireless communication system. First and second higher power level thresholds for signal transmissions of a cell are defined, wherein the first power level has a defined offset higher than a minimum required power level, and wherein the first and second power level thresholds define an operating power band therebetween. The user equipment measures a signal transmission power level. If the idle-mode user equipment determines that the signal transmission power level falls outside of the operating power band, then a message is sent to affect a change in signal transmission power level.

A method and apparatus for optimizing the mobile media received by a mobile device is disclosed. The apparatus operates with a radio access network, a mobile device operating in the radio access network, and a media server providing mobile media data to the mobile device wherein the mobile device connects to the media server using the radio access network. The apparatus includes a optimization application server coupled to the radio access network. The optimization application server includes positioning indexed performance information based on the positioning information and performance of a plurality of mobile devices operating in the radio access network. The optimization application server triggers adjustments to a parameter at least one of the radio access network, the mobile device and the media server by comparing the location of the mobile device in the radio access network to the optimization application server and sending a message to the radio access network to adjust the parameter.

In an Orthogonal Frequency Division Multiplexing communication system wherein a frequency bandwidth is divided into multiple sub-bands, a method and a scheduler is provided for configuring channel quality feedback for a point-to-multipoint communication session involving multiple users equipment (UEs). The scheduler receives multiple channel quality measurements from the multiple UEs and, based on the multiple channel quality measurements, determines whether to implement a frequency selective channel quality feedback scheme or a non-frequency selective channel quality feedback scheme for the point-to-multipoint communication session. The scheduler then implements the determined channel quality feedback scheme. In another embodiment of the invention, the scheduler may determine whether to implement a frequency selective or non-frequency selective channel quality feedback scheme based on a number of UEs serviced by the scheduler.

A system (100) includes a mobile station (125) to initiate an outgoing communication anywhere in a coverage area (115). A base station (110) and a radio access network (105) provide wireless service to the mobile station (125). The mobile station is paged in the sectors overlapping with only the clean zone. The mobile station (125) is paged in the sectors overlapping with the hot zone if the mobile station has predetermined trusted characteristics, or the mobile station is located within a clean zone of sectors overlapping with the hot zone, and an incoming communication for the mobile station originates from a predetermined trusted source. Existing calls to the mobile station are terminated in response to the existing call exceeding a predetermined threshold time limit, or a detected amount of voice activity in the existing call being below a predetermined threshold level.
