Abstract: To address the need to provide power control for listening participants of CDMA dispatch services, the concept of “shared channel signaling windows” for shared traffic channels (e.g., 110) is described. In one embodiment, the beginning of a signaling window is announced on the traffic channel and the remote units (e.g., MS 120) with the highest frame error rates compute the shortest transmit delays. For the duration of the window, remote units transmit their power control signaling according to their transmit delays. Thus, listening participants are given an opportunity, according to need, to perform power control signaling on the group traffic channel.

Abstract: A PDSN (18) includes a usage recording agent (19) for distinguishing between nonbillable and billable activity of a subscriber device 12. The usage recording agent (19) creates a record of a total number of bytes transmitted from the PDSN (18) to the RAN (14), counts bytes that are retransmitted from the PDSN (18) for providing a retransmitted byte total, and forwards the retransmitted byte total and the record to an AAA (28) so that the record can be adjusted in accordance with the retransmitted byte total.

Abstract: To address the need to provide listening participants of CDMA dispatch services soft handoff signaling capability, the concept of “shared channel signaling windows” for shared traffic channels (e.g., 110) is described. In one embodiment, the base site (105) announces the beginning of a signaling window for the traffic channel, allowing remote units (e.g., MS 120) that need to send handoff signaling an opportunity. In response to such signaling, the base site directs soft handoff information to the signaling remote units via the traffic channel. However, all the remote units that share the traffic channel can store this soft handoff information and later use the information to initiate soft handoffs without needing to exchange handoff messaging with the base site. Thus, a CDMA-dispatch, shared-channel implementation is enabled by providing soft handoff signaling windows and the over-the-air, soft-handoff messaging required for dispatch services is reduced.

Abstract: The present embodiments address the need for a reduced resource dormant state for packet data systems (100) that substantially provides the benefits of current dormant mode operation but without the resource maintenance costs. After a period of MS session inactivity, PCF resources, certain PDSN resources, and the PCF-PDSN tunnel are released in order to enter a new reduced resource dormant state. When data arrives for a reduced-resource-dormant MS (101), PDSN-initiated messaging (303) is used to trigger the re-establish PCF resources, a PDSN-PCF tunnel connection (320), and released PDSN resources.

Abstract: A system and method for transmitting information from a sender at a source mobile unit to a recipient at a destination mobile unit. A sender at a source mobile unit (102) may select a destination mobile unit (106). An overture element may then be formed. The overture element may contain information from the sender at the source mobile unit (102) indicating that the sender desires to establish a wireless connection with the recipient at the destination mobile unit (106). At least one data burst message may be formed and the overture element may be incorporated into the data burst message.

Abstract: A communication system, upon receiving an instruction to transfer deferrable data, determines whether an air interface is congested and, when the air interface is congested, defers a transfer of the deferrable data or transfers the deferrable, lower priority data as higher priority data. When, during a transfer of deferrable data, the system determines that the air interface is congested, the system may terminate the call and save a state of a partially completed deferred data transfer. Subsequent to the termination of the call, the system establishes another data connection over the air interface and transfers any remaining, not yet transferred deferrable data. In order to discourage subscribers from transferring higher priority data as lower priority data, the system may further restrict a transfer of lower priority data to designated time periods while allowing a transfer of higher priority data during the designated time periods and other time periods.

Abstract: An interconnect communication system is provided that provides for dispatch-type services including Instant Access call set up, talkgroup creation and management, and in-band floor arbitration and mode switching that employ in-band signaling tones. By providing talkgroup creation and management and in-band floor arbitration that are transparent to the underlying network, the talkgroup creation and management and in-band floor arbitration may be implemented in a legacy system without the need to modify the network and regardless of the type of network employed. Furthermore, by providing Instant Access call set up procedures and mode switching procedures that are capable of utilizing modified versions of known messages, the procedures may be implemented in a legacy system in a simplified manner, minimizing the impact of an addition of such procedures to a legacy network.

Abstract: To address the need for reducing the wireless data transfer delay without reducing channel utilization, an embodiment of this invention provides for a wireless unit (101), transitioning from a dormant to an active state, to transmit data, such as a data query, at the time of call origination. The Wireless Network delay and the Data Network delay, ordinarily experienced back-to-back, are instead experienced concurrently. The difference in delay experienced between active versus dormant users is thus nearly eliminated. This will motivate network operators to decrease their inactivity timers, and is thereby likely to improve their channel utilization and reduce the cost of packet data services.

Abstract: A packet data communication system that includes an infrastructure in wireless communication with a mobile station provides a data service selection to a user of a mobile station. The infrastructure receives packet data intended for the mobile station, wherein the data packet comprises information concerning a domain sourcing the packet data and an intended destination of the packet data. The infrastructure then conveys the domain information to the mobile station, wherein the domain information allows the mobile station to determine whether to receive the packet data or to activate a packet data service.

Abstract: A packet data communication system that includes a base station subsystem (BSS) operably coupled to a packet control function (PCF) via an A8/A9 interface and a packet data service node (PDSN) operably coupled to the PCF via an A10/A11 interface provides accounting updates concerning data received and/or transmitted by the BSS. The BSS determines a quantity of data received by the BSS from, and/or transmitted by the BSS to, a mobile station and conveys a first set of information concerning the determined quantity of data to the PCF. In response to receiving the first set of information, the PCF conveys a second set of information concerning the determined quantity of data to the PDSN. In response to receiving the second set of information, the PDSN conveys a third set of information concerning the determined quantity of data to a billing service.

Abstract: To address the need for reducing wireless data transfer delay, an embodiment of this invention provides for a radio access network (RAN) (110) to transmit data, such as a data query, at the time of paging a dormant wireless unit (101). By transmitting the data at this time, wireless unit activity in response to the data can begin while the paging and traffic channel setup proceed. Thus, once established, the traffic channel will be idle for less time than under the present practice were data is not sent until the traffic channel setup is completed. Less idle traffic channel time is expected to improve channel utilization and contribute to lower packet data costs.

Abstract: A network element (204) acting as an intermediary between two peers (202, 206) monitors for control messages exchanged between the two peers when establishing a point to point protocol session. Relevant parameters within such control messages are stored (612) for later use. When retransmitted control messages are detected (610), the network element processes the retransmitted control message based on the stored parameters (618) such that additional negotiation loops are avoided. In this manner, the effects of non-simultaneous link establishment and differing timeout timers are mitigated by the network element.

Abstract: A method is disclosed of reducing data loss during cellular handoff of a mobile among base sites by detecting an end-of-line signal by a fax adapter (13a or 106a) from the transmitting fax, buffering (13b or 106b) subsequent fax information, and transmitting filler bits in place of the EOL and buffered information.
