摘要:
A two-stage method is used to page a target mobile station. A wireless network transmits an initial page message into a plurality of wireless coverage areas (e.g., the wireless coverage areas defined by a paging zone) that includes the target mobile station's last reported location. The initial page message is received by a plurality of mobile stations, which then transmit a plurality of responses. The plurality of responses includes a target response from the target mobile station. The wireless network determines the target wireless coverage area that received the target response and then transmits a supplemental page message into the target wireless coverage area. The initial page message may be a very short message, such as a page indicator, that does not identify the target mobile station. The supplemental page message may be a longer message that identifies the target mobile station and the reason for the page.

Disclosed is a method and device for managing handoff of an access terminal in a radio access network (RAN). An access terminal may detect a handoff trigger, determine whether there is an ongoing data transfer in progress, determine an amount remaining in the data transfer, compare the amount remaining to a threshold amount, and delay or cancel the handoff if the amount remaining is below the threshold amount. Additionally, the access terminal may consider signal strength of the current (source) coverage area in determining whether to delay or cancel the handoff.

Exemplary methods and systems are described that may be employed in a radio access network in order to aggregate the power-control messages from the sectors in a mobile station's active set, and provide an aggregate reverse-link power-control indication, in all active sectors. To do so, an exemplary base station may periodically determine an appropriate reverse-link power adjustment for a mobile station. However, rather than immediately send power-adjustment indications to the mobile station, each base station serving an active sector is preferably configured to send the power-adjustment indication to mobile switching center. The mobile switching center then determines an aggregate power-control indication for the mobile station. The aggregate power-control indication may then be transmitted to the mobile station in each of the mobile station's active sectors.

An access terminal may be requesting from an access network data in a first coverage area at a first data rate, which is determined based on at least one signal condition of the first coverage area. The access terminal may then decide to switch from requesting data in a first coverage area to requesting data in a second coverage area. In response, the access terminal may (a) request data in the first coverage area at an increased second data rate and (b) send to the access network a notification of the decision to switch from requesting data in a first coverage area to requesting data in a second coverage area. After sending the notification, the access terminal may request data in the second coverage area at a third data rate, which is determined based on at least one signal condition of the second coverage area.

A power control command (PCC) transmission scheme is disclosed. In one embodiment, the PCC transmission scheme may involve an access network engaging in a respective communication session with each of a plurality of access terminals on a given wireless link and sending a respective series of PCCs directed to each of the plurality of access terminals on the given wireless link. Based on a power utilization of the given wireless link, the access network may then decide to adjust a transmission rate at which to send PCCs directed to a set of access terminals in the plurality of access terminals. In turn, the access network may send the respective series of PCCs directed to each of the set of access terminals at the adjusted transmission rate.

Disclosed herein are methods and systems for managing usage of traffic-channel resources in an access network, which are preferably resources that are reserved during a traffic channel assignment (TCA) process. An exemplary method comprises (i) a base station determining a usage level of at least one traffic-channel resource in a coverage area of the access network; (ii) based at least in part on the determined usage level, updating one or more TCA parameters affecting expected usage of the traffic-channel resource resulting from the TCA process; and (iii) performing the TCA process according to the updated TCA parameters. Preferably the usage level is determined for Medium Access Control Identifiers (MAC_IDs). Further, the access-channel occupancy (ACO) may be determined and the base station may further base the updating of TCA parameters on the ACO. In an exemplary embodiment, the updated TCA parameters include the TCA count and/or the TCC wait timer.

What is disclosed is a method of operating a wireless communication device. The method includes, while at an initial location, entering a first wireless communication mode that requires tuning to a first frequency spectrum. In response to entering the first wireless communication mode, the method includes setting a timer for monitoring a second wireless communication mode. When the timer expires, the method includes determining if a present location of the wireless communication device is beyond a threshold distance from the initial location. If the present location is beyond the threshold distance from the initial location, then the method includes tuning away from the first frequency spectrum to a second frequency spectrum for the second wireless communication mode and monitoring information for the second wireless communication mode, and if the present location is not beyond the threshold distance from the initial location, then resetting the timer for monitoring the second wireless communication mode.
摘要:
While a first and second entity are engaging in a communication session on a wireless link, the first entity may be sending a series of power control commands (PCCs) directed to the second entity at a first transmission rate. Additionally, the first entity may monitor an actual and expected transmission-power adjustment of the second entity. Based on this monitored actual and expected transmission-power adjustment, the first entity may decide to alter the PCC transmission scheme for the second entity. For instance, if the monitored actual and expected transmission-power adjustment differs by a threshold extent, the power-controlling entity may decide to increase the PCC transmission rate for the power-controlled entity and/or increase the transmission-power adjustment instructed by PCCs directed to the second entity. In response, the first entity may begin sending the series of PCCs directed to the second entity according to the altered PCC transmission scheme.
