摘要:
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.

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.

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.

A change in user interest level of a user application of a client device in communication with a network infrastructure at a first quality of service level is assessed (306). In response, the quality of service associated with the user application is dynamically changed (308) to a second quality of service level, while keeping the user application active, based, at least in part, on the change in user interest level of the user application.

A method and system for providing credit for participation in an ad hoc wireless communication network is useful for improving network efficiency. The method includes receiving at a first network node a first data packet transmitted from a second network node (step 305). The first data packet includes payload data and credit claim data. The first node then determines that the credit claim data should be forwarded to a credit accounting authority (step 310), so a second data packet is then transmitted from the first node to the credit accounting authority (step 315). The second data packet includes some of the credit claim data. The first node then transmits a third data packet to a third network node, where the third data packet includes the payload data (step 320).

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.

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.
