International Classification:

H04Q007/20

US Classification:

455466, 455453, 455458

Abstract:

The need to reduce the cost associated with signaling mobiles () across multiple cells () is addressed by embodiments of the present invention. A targeted MS is initially paged only in those cells in which the paging channel loading level is below a particular paging threshold. Similarly for short messaging, the RAN transmits the short messaging to the MS only in those cells in which the paging channel loading level is below a short messaging threshold. Therefore, the MS can be signaled in under-loaded cells first, were the effect on system capacity and performance is negligible. When successful, the MS signaling is achieved at a lower cost to the system than when loaded cells are involved.

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.

International Classification:

H04J 3/00

US Classification:

370345, 455518, 455519

Abstract:

To address the need for a dispatch mobile () to more quickly make a call, in the preferred embodiment of the present invention those remote units operating in a dispatch mode () will receive a first slot cycle, while those remote units not operating in a dispatch mode () will receive a second slot cycle. The second slot cycle is greater than the first slot cycle, so that those remote units operating in dispatch mode () will “wake up” during the slot cycle normally utilized for interconnect calls. Because shorter slot cycles are utilized for remote units operating in dispatch mode (), the time it takes to make a dispatch call is greatly reduced. Additionally the minimum slot cycle duration typically used for standard calls remains unchanged, greatly conserving battery life.

International Classification:

H04B 7/00

US Classification:

455518, 455519, 370312

Abstract:

The need to decrease paging-related delays in wireless systems () is addressed by embodiments herein. A RAN () anticipates that an MS () is likely to be a target of communication not yet initiated. In one embodiment, a traffic channel is assigned to the MS, when a loading level of a serving cell of the MS is below an assignment threshold. This avoids paging-related delays for the MS should the MS become a target of communication. In another embodiment, the MS is signaled to transition to at least one operational mode in which paging-related delays for the MS are reduced. Such modes include a semi-dormant mode, an unslotted mode, a control hold mode, a speculative scanning mode, and a reduced slot cycle index (RSCI) mode. This allows the MS to begin participating in communication more quickly than it otherwise would, should communication targeting the MS be initiated.

Abstract:

Various embodiments are described herein to address the need for reducing call setup delays with respect to supplemental channels. Modifications to channel assignment messaging (), such as an enhanced ECAM, and service connection messaging (), such as an enhanced SCM, are described. These modifications enable the assignment of SCHs () earlier in the call setup sequence. In addition, embodiments for determining and anticipating when such modified messaging may effectively speed the transfer of data (including VoIP) between a BS () and an MS () are described.

Abstract:

Various embodiments are described for establishing a group call session serially. After receiving a serial group call request from a remote unit (), fixed network equipment (FNE) () selects a first subset of members () from the targeted group () of units and signals those members to join the group call session. Various techniques for selecting the first subset may be employed depending on what system benefits are desired. A second subset of members () from the targeted group of units is also selected and signaled to join the session. This second subset may be used to invite additional units in order to achieve a maximum number of group participants. Alternatively, the second subset may be used to invite a different unit (or units) to participate. This can be triggered by a user request to invite another subset to the group session, as could occur when the user is not able to resolve the particular matter at-hand with the group members of the first subset.

International Classification:

G08C 17/00
H04Q 7/00

US Classification:

370311, 370328

Abstract:

Various embodiments are described for signaling an ad-hoc group of mobile units (MUs). The ad-hoc group may be a group of MUs for which signaling awaits transmission via a wireless communication resource (). Signaling such a group involves deriving a mobile unit group identifier (MUGI) by combining individual mobile unit identifiers (MUIs) of the targeted ad-hoc group. The individual MUIs are either an identifier of each MU or derived from an identifier of each MU. The derived MUGI is then included in combined signaling that is transmitted (by RAN , e. g. ) via the wireless communication resource. A receiving MU () determines whether the MUGI could have been derived from its MUI in combination with at least one other MU's MUI. When it determines that the MUGI could have been derived from its MUI, the receiving MU processes the signaling as directed to itself.
