摘要:
A communication system is provided that minimizes access message collisions when multiple mobile stations attempt to access a network after updating configuration information and/or access parameters information via a same overhead message by providing for each such mobile station to determine whether, or when, to convey an access message based on a time period corresponding to a wait for the overhead message by the mobile station.

A communication device [400] includes a transceiver [405] to receive and transmit data. A message detection element [410] detects at least a first message and a second message in the data received by the transceiver [405]. A processor [400] modifies a state of the communication device [400] based on the first message and the second message. A positive acknowledgement is transmitted in response to the first message comprising a call pending message, and the state is modified to establish a session and inhibit an alerting of a user of the communication device. The state is modified to alert the user of the communication device [400] in response to the second message comprising a call start message.

The present invention provides a system and method for communication based on an availability level of a presence entity in a communication network that includes a first step (400) of configuring at least one privacy rule for a communication service, wherein the at least one privacy rule is associated with the presence entity and assigns a potential caller to a prioritized group. A next step (402) includes receiving an indication of availability of the presence entity. A next step (404) includes controlling communication access with the presence entity based on the at least one privacy rule, wherein communication access between the presence entity and the caller is controlled by the priority for that caller and the availability indication of the presence entity.

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 user initiates a group call from an initiating communication device to a plurality of group call recipients' communication devices. Then, a processor circuit determines a wait time for commencing communication of the group call according to a predetermined function. The predetermined function is based least in part on status information for at least a portion of the group call recipients wherein the status information includes a likelihood of participation in the group call. The status information used as part of the predetermined function may include various factors relevant to the likelihood of or expecting timing of a group call recipient's joining the call. Perceived delays can be further reduced by storing group call media prior to sending the media to or playing the media at a particular group call recipients' communication devices.

A system (100) and method (200) is provided to customize services (150). The method can include conveying (204) access network information from a user device to a core network using a SIP message, and adapting (206) a service provided by the core network according to the access network information contained in the SIP message. The method can include creating a header field to convey the access network information. A roaming status indictor can be included in a SIP SUBSCRIBE, a SIP INVITE, a SIP MESSAGE or a SIP REGISTER for adapting the delivery of presence state information concerning a resource.

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 (111). 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 121, e.g.) via the wireless communication resource. A receiving MU (101) 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.

A system [100] includes a target set of communication devices [105] for a group call. An originator communication device [102] transmits a group call initiation for the group call. A communication and processing device [125] sequentially invites the target set of communication devices in response to detecting at least one predetermined characteristic of the group call. The sequentially inviting the communication devices comprises (a) initially inviting a first subset [130] of the target set of communication devices that comprising required communication devices, (b) subsequently invites a second subset [135] of the target set of communication devices in response to determining that the group call will be initiated, and (c) joins targets of the second subset of the target set of communication devices accepting the call initiation message to a communication session involving first targets of the first subset of the target set of communication devices accepting the call initiation message.

摘要:
The need to decrease paging-related delays in wireless systems (100) is addressed by embodiments herein. A RAN (201) anticipates that an MS (120) 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.
