Abstract: An agent is configured to receive queries from an application server in a communication network. The queries are directed to one or more devices in the communication network. The agent selects a communication path for a device from a plurality of communication paths from the application server to the device. The communication path is selected based on a data size that is to be sent to the device as part of the query, a number of devices that are to receive the query, or a combination thereof. The agent transmits the query via the selected communication path. The communication path can be selected based on one or more of a time criticality of the query, a subscription class of a user of the device, a category of a type of the device, an operator-defined influence factor, network conditions along the communication path, a broadcast flag in the query, or a combination thereof.

Abstract: Method and Apparatus to Derive System Timing at a Wireless Base transceiver Station (BTS). The present invention relates to wireless communication networks and, more particularly, to timing information in wireless communication networks. A method for providing reference timing to a BTS, the method comprising of the BTS sending a message to a network controller via a station, wherein the message requests for round trip delay time incurred by the message; the BTS estimating a timing offset from a response and determining the correction to be made to the reference timing using the timing offset due to the one way delay from the station transmitting the pilot signal, the actual PN offset at which the station transmits the pilot signal and the actual offset at which the pilot signal is received at the BTS; and the BTS making the correction to the reference timing.

Abstract: In one embodiment, the access terminal (AT) receives a switching ratio, the AT randomly generates a serving priority value from a uniformly distributed random variable, and the AT determines whether to switch from the first carrier and attach to one of the neighboring carriers based on the serving priority value and the switching ratio.

Abstract: An access terminal supports both a longer wakeup period and a shorter wakeup period (lower frequency of wakeups and higher frequency of wakeups, respectively) where the time interval over which the short wakeup period is active is prescheduled or enabled based on needs. Thus, when paging of the access terminal is expected to occur within a known interval of time, the access terminal enters a standby mode and is awoken more frequently during that interval.

Abstract: The present invention provides methods involving at least one access terminal and at least one access network. The methods may include providing or receiving information indicative of future accessibility of at least one access network.

Abstract: Handoffs within a wireless communication system (20) include using a common cell definition code for each of a plurality of microcell BTSs (30, 40, 50) to facilitate handoffs between a macrocell (26) and any one of the microcells. In a disclosed example, a common cell definition code such as a PN offset or a scrambling code is used to trigger a handoff from the macrocell (26) to any one of the microcell BTSs (30, 40, 50). A mobile station locate feature identifies which of the BTSs is involved in the handoff. Another common cell definition code is used in one example to trigger all handoffs from any one of the microcells (30, 40, 50) to the macrocell (26). Soft handoff and hard handoff examples are disclosed.

Abstract: The present invention provides a method of call admission to a wireless network. The method may include accessing quality of service information associated with a voice application associated with an access terminal in response to receiving a call session request from the access terminal. The method may also include determining whether to admit the requested call session based on the quality of service information associated with the voice application.

Abstract: There is provided a system and method for providing group calling in a wireless network. More specifically, in one embodiment, there is provided a method comprising receiving a request to participate a group call from a mobile device located in a wireless service area, determining whether a threshold number of other mobile devices in the wireless service area are participating in the group call, if the threshold number of the other mobile devices are participating in the group call, designating the requesting mobile device to receive a multicast transmission of the group call, and if the threshold number of other mobile devices are not participating in the group call, designating the requesting mobile device to receive a unicast transmission of the group call.

Abstract: The present invention provides a method is provided for blocking alert messages to mobile units. The method includes determining at least one location of at least one mobile unit based on at least one response to a first page message provided to the at least one mobile unit. The method also includes interrupting transmissions to the at least one mobile unit based on said at least one determined location of said at least one mobile unit.

Abstract: A method is provided for locating an access terminal using paging. The method comprises selecting one of a first and second paging scheme based on a quality of service associated with the access terminal. That is, a resource intensive paging scheme may be employed to locate access terminals that have been assigned a relatively high quality of service, and a slower, less resource intensive, paging scheme may be used when the access terminal has a relatively low quality of service.

Abstract: The present invention may provide a method of communication that includes selecting at least one access channel for transmission of data based on a channel condition. The present invention may also provide a method of communication that includes receiving data over at least one access channel selected for transmission based on a channel condition.

Abstract: In a 3G CDMA2000 IS-2000 wireless communications system, a base station at the border between two packet zones, transmits an Extended System Parameters message that includes the identity of a primary packet zone supported by that base station as well as the identities other secondary adjoining packet zones supported by that base station. When transiting the borders between packet zones, a dormant mobile terminal will not request a reconnection until its current packet zone is no longer listed in the Extended System Parameters message received from the base station in the cell in which it is currently located. Thus, the mobile terminal will not need to repeatedly initiate a reconnection in each packet zone as moves back and forth across packet zone borders. Alternatively, the Extended System Parameters message includes a special value packet zone identity that is interpreted by the receiving mobile terminal to mean “no change.

Abstract: In real-time critical wireless data applications, such as Push-to-talk over Cellular (PoC) or Push-To-Talk (PTT) and Voice-over-IP (VoIP), a user of a PTT mobile station pushes a button to indicate his desire to communicate with a pre-defined group (e.g., a buddy list) of people. This action triggers the PTT mobile station to re-activate a dormant data call connection and request the floor. When one or more of the mobile stations identified in the buddy list responds, a PTT server sends a Grant message to the PTT caller and he/she can start to talk. In one embodiment, the Grant message is sent to the PTT caller before the dormant call is completely reactivated to reduce PTT call setup latency.

Abstract: A push-to-talk over cellular (PoC) system is provided in which a negative indication-to-speak may be delivered to a requesting unit when the requested wireless unit is not available. In one embodiment of the instant invention, a first wireless unit is paged in response to receiving a request from the second wireless unit to transmit a message to the first wireless unit. A page response signal is received from the first wireless unit, and the negative indication-to-speak to the second wireless unit is delivered to the second wireless unit in response to receiving the page response signal.

Abstract: The method described herein is useful in a push-to-talk over cellular (PoC) system to provide an accurate but low-latency indication-to-speak. Generally, the method may be referred to as a page-event confirmed indication-to-speak. The page-event confirmed indication-to-speak accurately confirms a targeted but dormant mobile station is within radio reach by first sending a paging message to the dormant mobile station. When the dormant mobile station responds to the page message, an indication-to-speak is delivered to an initiating mobile station to indicate to the user that he/she may now speak.

Abstract: In a wireless communication system, a method includes monitoring an error condition on an active communication channel, establishing a simultaneous communication channel, and searching the simultaneous communications channel while continuing to monitor the active communication channel.
