Abstract: A method and system for providing connections from a wireless access point. The wireless access point has multiple VPN tunnels. The access point detects a wireless-network identifier (such as a service set identifier (SSID)) provided by a terminal via an air interface, and the access point uses the wireless-network identifier as a basis to select one of the VPN tunnels. The access point then sends communication from the terminal via the selected VPN tunnel.

Abstract: Methods and systems are provided for conducting power control based on reverse-link RF conditions. In an embodiment, a base station periodically calculates a reverse noise rise (RNR), periodically calculates a collective reverse-link frame error rate (RFER), and periodically checks whether a new call-origination message has been received. If a call origination has not been received, the base station checks whether the RNR is less than a threshold. If the RNR is less than the threshold, the base station sends power-up commands to each of mobile stations. If the RNR is not less than the threshold, the base station sends power-down commands to each of the mobile stations so long as the collective RFER is less than a maximum RFER. If a call origination has been received, the base station sends power-down commands to each of the mobile stations until the collective RFER reaches the maximum RFER.

Abstract: The present invention provides systems and methods for controlling the volume of a remote communication terminal (RCT) based on the amount of force asserted on the session button of an originating communication terminal (OCT). The OCT may include a force-sensor that detects the force exerted on the session button and provides an output corresponding with the detected level of force. While the force is being exerted on the session button, the OCT receives voice from the user and transmits a representation of the voice via the communication interface for receipt by the RCT and for playout of the voice by the RCT. The OCT includes with the transmitted representation of the voice a playout-volume directive that corresponds with the output from the force-sensor, and causes the RCT to play out the voice at a volume level corresponding with the detected level of force.

Abstract: Methods and systems are provided for increasing and decreasing a power level of a forward-link overhead channel. In an embodiment, a BTS (i) receives from at least one mobile station an increase request, each increase request requesting that the BTS increase a power level of a forward-link overhead channel, (ii) makes a first determination that at least a first threshold number of mobile stations have sent an increase request within a first request window, wherein the first request window is a period of time, and (iii) in response to making the first determination, increases the power level of the forward-link overhead channel.

Abstract: 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.

Abstract: A method and mobile diagnostic measurement tool is described for collecting cellular network performance data. The method includes determining a current data rate for transmission of data between the measurement tool and a network node in a cellular network. The measurement tool includes a controller adaptively controlling the collection of network performance data by one or more data collection units in the measurement tool in accordance with variations in the current data rate. The collection of data is controlled so as to keep the total rate of collection of data to be less than or equal to the rate at which the data is transmitted to the network node. A memory in the tool may stored log mask tables which indicate which types of performance data can eliminated in the collection process depending on the transmit data rate.

Abstract: Methods are disclosed for initiating a handoff of a wireless access terminal based on a set of one or more factors including the determined value of the Reverse Activity Bit (RAB). The set of one or more factors may also further include (i) a determined round-trip delay for a bi-directional communications link between the first wireless access node and the wireless access terminal, wherein the bi-directional communications link comprises a forward link from the first wireless access node to the wireless access terminal and a reverse link from the wireless access terminal to the first wireless access node, and/or (ii) a determined forward-link signal-strength indicator for a forward link from the first wireless access node to the wireless access terminal.

Abstract: Disclosed herein is a method for selecting one or more capsules in which to include a traffic channel assignment message. The method may involve: (a) receiving a request from an access terminal to engage in a communication session; (b) making a determination as to whether or not the communication session is of a type that is designated for priority service; and (c) using the determination of whether or not the requested communication session is of a type that is designated for priority service as a basis for selecting one or more capsules in which to include the traffic channel assignment message. According to an exemplary embodiment, for priority communications, the TCA message is sent in all sectors identified in a route update message from the access terminal, and for non-priority communication sessions, control channel occupancy and pilot-signal strength to select sectors for the TCA message.

Abstract: A method and system is disclosed for optimizing handoff of access terminals. In particular, when (i) a given access terminal must switch from a first channel band in a first coverage area to a second channel band in order to hand off to a second coverage area, and (ii) there are no available identifiers to assign to the given access terminal to facilitate making the switch from the first channel band to the second channel band in the first coverage area prior to handing off to the second coverage area, an appropriate identifier is advantageously reassigned from another access terminal to the given access terminal. With the reassigned identifier, the given access terminal may then switch to the second channel band in the first coverage area prior to handing off to the second coverage area.

Abstract: Methods and systems are provided for using femtocells to address macro-network backhaul congestion. In an embodiment, a macro base transceiver station (BTS) that has a backhaul connection to a radio network controller (RNC) detects that a current utilization of the backhaul exceeds a backhaul-congestion threshold, and responsively identifies one or more sector-carriers having a respective current air-interface utilization that is less than a respective sector-carrier-congestion threshold for the respective sector-carrier. The macro BTS further identifies one or more femtocells that are positioned in the coverage area of the one or more identified sector-carriers, and offloads some reverse-link traffic to each identified femtocell over the forward link of an identified sector-carrier in whose coverage area the respective identified femtocell is positioned, for forwarding of the offloaded traffic by the one or more identified femtocells over a packet-data network to an intended destination.

Abstract: Methods and systems are provided for providing wireless service using multiple protocols on a single radio-frequency (RF) carrier. According to an embodiment, a low-cost Internet base station (LCIB) provides wireless service on an RF carrier using a first wireless-communication protocol and provides wireless service on the RF carrier using a second wireless-communication protocol, where providing wireless service on the RF carrier using the first wireless-communication protocol and providing wireless service on the RF carrier using the second wireless-communication protocol occur at different times. The LCIB may alternate between providing wireless service using the first wireless-communication protocol and providing wireless service using the second wireless-communication protocol.

Abstract: A method and apparatus for automatically adjusting the frequency of content background-downloading. An apparatus such as a cell phone, personal digital assistant, or computer, will be set to perform background-downloads of content at a particular frequency. The apparatus will then determine the frequency with which a user accesses background-downloaded content on the device, and the apparatus will use the determined frequency as a basis to automatically adjust the background-download frequency. For instance, if the user-access frequency is greater than the background-download frequency, then the apparatus may increase the background-download frequency, whereas, if the user-access frequency is less than the background-download frequency, then the apparatus may decrease the background-download frequency.

Abstract: A method for causing a calling client station to obtain content from a network server in response to a trigger signal received by the client during the ringback period for a call. The trigger signal is transmitted from a ringback server to a calling client station during the ringback period of call setup, whereby the trigger signal, once received and recognized by the calling client station, causes the station to request and obtain content from a network server. In another aspect, a method for providing content to a calling client station by transmitting a trigger signal to the calling client station during call setup, thereafter receiving at a network-based content server a request from the calling client station, generated in response to the trigger, for a content-download, and providing the content-download in response to the request.

Abstract: A method and system for providing connections from a wireless access point. The wireless access point has multiple sets of predefined VPN security settings. The access point detects a wireless-network identifier (such as a service set identifier (SSID)) provided by a terminal via an air interface, and the access point uses the wireless-network identifier as a basis to select one of the sets of predefined VPN security settings and to responsively establish a VPN tunnel extending between the access point and a remote VPN terminator.

Abstract: Disclosed herein is a cellular telephone that does not include an integrated microphone and an integrated speaker but that instead requires use of an externally connected microphone and speaker to facilitate voice communication. By omitting any integrated microphone and integrated speaker, the cellular telephone may have increased surface area usable for other purposes, such as a display or keypad. Further, the cost to manufacture the cellular telephone could be incrementally lower than the cost to manufacture a comparable cellular telephone having an integrated microphone and integrated speaker.

Abstract: Methods and systems for determining the density and velocity of wireless communication devices (WCDs) on a road are provided. A preferred embodiment involves determining a set of WCDs that are being served by a plurality of wireless coverage areas that intersect the road. This set of WCDs is narrowed to include only those WCDs that are (1) presumed to be in motion and (2) within a predefined geographic definition of the road. The density and aggregate velocity of the resulting WCDs is determined. From these determinations, the traffic density and aggregate traffic velocity of vehicles on the road can be estimated and an associated output can be provided.

Abstract: A method and system for selectively applying a cellular-PBX integration service. When a radio access network (RAN) receives a call request seeking to set up a call for a cellular wireless communication device (WCD) that is operating in the coverage area of the RAN, a determination is made as to whether the WCD is currently checked-into a cellular-PBX integration service. A service control point (SCP), for instance, may make the determination. If the determination is that the WCD is currently checked-in, then the call is set up to an IP PBX server that services the WCD, and the IP PBX server may then handle the call as it would handle a call placed to any IP PBX extension. Further, differential billing can be applied, charging an enterprise billing-account for the call if the WCD is checked-in, and charging a WCD billing-account for the call if the WCD is not checked-in.

Abstract: A method and system for conferencing a landline telephone into a cellular telephone call is disclosed. In response to a landline telephone going off-hook, a cellular telephone corresponding to the landline telephone is identified. When a determination is made that the corresponding cellular telephone is currently engaged in a call, the landline telephone is conferenced into the cellular call. If the cellular telephone is subsequently disengaged from the call, the original cellular call has been effectively transferred to the landline telephone. The inventive method and system may be linked to a cellular-landline conference call service. For example, a user may subscribe to such a service so that the user may automatically transfer a call from the user's cellular telephone to the user's home or office landline telephone when that landline telephone is taken off-hook.
