A communication device minimizes an opportunity for a queue stall during a communication session employing a reliable transport protocol by setting a current mode of operation for a Radio Link Protocol (RLP) and, based on a quality of an air interface, switching to an RLP mode of operation different from the current mode during the communication session.

Method and apparatus for dynamically changing modes of a reliable transport protocol

A communication system is provided that routes a bearer path of a communication session between an originating Node B and a terminating Node B via an X2 interface, bypassing an IMS core network, while continuing to route the signaling path to an IMS network, thereby allowing the IMS network to retain control of the bearer path while avoiding delay, potential for data loss and jitter to the bearer stream, and additional backhaul capacity requirements that result from routing the bearer path between the originating and terminating Node Bs via the IMS core network. In determining whether the bearer path may bypass the IMS core network, the communication system determines whether IMS core network bearer associated services are required for the communication session such that a bearer path of the call will need to be routed to the IMS core network in order to provide such services.

A system, method, and wireless device for determining a forward channel rate for wirelessly communicating information to a wireless communication device is disclosed. The method includes receiving data rate control information from each wireless communication device () in a plurality of wireless communication devices (). The method also comprises requesting a set of information. The data rate control information includes signal strength information associated with each of the wireless communication devices (). The data rate control information received from each of the wireless communication devices is compared to each other. A modulation and coding scheme is determined for wirelessly communicating the set of information to the plurality of wireless communication devices. The modulation and coding scheme is based on the data rate control information associated with a wireless communication device () having a weakest signal strength.

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.

Method and apparatus for providing deferable data services in a cellular communication system

A method and a system for scheduling requests generated for a plurality of mobile devices in a communication network () has been disclosed. The requests are generated for a transmission opportunity. The method includes computing a sort metric () for each request, based on an information update. A lead-time is then computed () with respect to a drop-dead time for each request, based on the sort metric for a time slice. The drop-dead time for a given time slice is the time before which scheduling has to be done so that data can be transmitted during the given time slice. Each request may be considered () for allocation in the time slice before the beginning of a next time slice, based on the lead-time.

Method and system for scheduling requests in a non-first in first out (FIFO) order in a network

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). 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), so a second data packet is then transmitted from the first node to the credit accounting authority (step). 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).

An apparatus and method for efficient transitions between operating states in a communication network, includes a preliminary step of having a mobile station in a Dormant or Idle state. A next step includes requiring a data transfer, either to or from the mobile station. A next step includes transitioning the mobile station from the Dormant or Idle to an Active state. A next step includes transferring a bearer path context for the data from a Paging Control Function (PCF) to an RF Bearer Function. This can include creating a tunnel using an Inter-PCF handoff procedure. The result is a direct connection between an RF Bearer Function and an IP Router, without the PCF being in the data path.

The present embodiments address the need for a reduced resource dormant state for packet data systems () 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 (), PDSN-initiated messaging () is used to trigger the re-establish PCF resources, a PDSN-PCF tunnel connection (), and released PDSN resources.

Method and apparatus for supporting a reduced resource dormant state for packet data

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.

To address the need for reducing wireless data transfer delay, an embodiment of this invention provides for a radio access network (RAN) () to transmit data, such as a data query, at the time of paging a dormant wireless unit (). 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.

Method and apparatus for wireless data transfer with reduced delay

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