摘要:
A mobile station involved in a call receives a forward link signal from a radio access network (RAN) and transmits a reverse link signal to the RAN. If the mobile station detects a reception failure of the forward link signal, such as the receipt of an errored frame, the mobile station transmits a wait time to the RAN. The wait time specifies how long the reception failure can continue before the mobile station will discontinue transmitting the reverse link signal. In response, the RAN may increase the transmit power level at which the RAN transmits the forward link signal, such that a maximum transmit power level is reached during the wait time. The wait time could be based on a user preference and/or user behavior with respect to abandoning calls.

Disclosed herein are systems and methods for enforcing vendor-based restrictions on wireless service. One embodiment takes the form of a method that is carried out by at least one radio access network (RAN) entity and that includes receiving an access request from a mobile station via a base station, and responsively making a vendor identification to identify a vendor of the base station. The method further includes denying the access request based at least in part on the vendor identification.

A method and system for dynamically controlling the transmission of reverse-link control signals to help reduce interference on the reverse link. A RAN identifies a mobile device whose transmission of reverse-link control signals best represents the reverse-link air interface condition of each other mobile device in a plurality of mobile devices. Then the RAN causes each mobile device in the plurality other than the identified mobile device to not send its respective reverse-link control signal at a given time, thereby reducing the number of mobile devices that transmit reverse-link control signals at the given time.

Disclosed herein are a method and a corresponding apparatus that provides a tethering alert if the apparatus is tethering data. In one example, a method for providing a tethering alert by an apparatus having a first network communication interface and a second network communication interface is disclosed. The method includes i) receiving incoming data via one of the first network communication interface and the second network communication interface, ii) sending outgoing data via the other of the first network communication interface and the second network communication interface, iii) making a determination that there is a threshold similarity between the incoming data and the outgoing data, and iv) responsive to making the determination, the apparatus providing a tethering alert indicating that the apparatus is tethering data.

Disclosed are systems and methods for providing system-acquisition parameters on standardized frequencies. One embodiment takes the form of a method for assisting mobile devices with system acquisition. The method includes, in each of two or more wireless coverage areas, broadcasting from a radio access network (RAN) on each of one or more predefined frequencies one or more sets of one or more system-acquisition parameters. The method also includes configuring one or more mobile devices with logic executable for, in response to detecting a triggering event, retrieving at least one of the sets of system-acquisition parameters on at least one of the predefined frequencies, and then using at least one retrieved set of system-acquisition parameters to attempt to acquire system connectivity.

During a first time interval, an access point transmits orthogonal frequency division multiplexing (OFDM) signals using a first cyclic prefix length. The access point selects a second cyclic prefix length based, at least in part, on the load of the access point. The access point transmits OFDM signals using the second cyclic prefix length during a second time interval. The load of the access point may be determined based on the amount of downlink data being buffered in the access point for transmission to one or more user devices.

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 method and system for managing broadcast of notifications indicating whether system information has changed, so as to enable served devices to determine when to read and store updated system information. A radio access network tracks changes in system information on a per wakeup cycle basis, so as to determine whether system information has changed since a last instance of broadcasting such a notification in a particular wakeup cycle. If system information has changed, the network responsively broadcasts an indication that system information has changed, so as to cause devices operating on that wakeup cycle to read and store the updated system information. Whereas, if system information has not changed, the network responsively broadcasts an indication that system information has not changed (or forgoes broadcasting an indication that system information has changed), so that devices operating on that wakeup cycle can avoid reading and storing the system information.
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.

A method and system for dynamically adjusting reverse-link ACK transmission power based on forward-link timeslot utilization. A radio access network (e.g., a base station) may monitor timeslot utilization on the forward link and, upon detecting that the timeslot utilization is threshold high, may cause one or more served access terminals to increase their ACK transmission power, thereby possibly helping to minimize re-transmissions for data packets that have already been successfully received, and thus helping to minimize unnecessary use of potentially scarce forward-link timeslots.
