Abstract: Presence information associated with a presence entity (102) is received. A composition rule associated with the presence information is also received. The composition rule is applied to the presence information in order to determine a presence state for the presence entity (102).

Abstract: These various embodiments are usable in a context that comprises a first network that serves to communicatively couple an entity within a second network (which second network is different than the first network) with an end user platform. Pursuant to these teachings this entity is identified as having a predetermined status with respect to being provided with information regarding at least one first network event. When the first network event is detected within the first network, a message is provided to the entity regarding this first network event. By one approach the entity can acquire the indicated status via a subscription process.

Abstract: A communication system provides network-based battery power management that may be transparent to a user of a mobile station (MS). When one or more elements of a network of the communication system determines that the MS is operating at a low power supply charge level and/or has experienced a significant change in a charging level of the power supply, the one or more network elements may arrange for postponement of delivery of a delay-tolerant service to the MS or for adjustment of one or more of a characteristic of a service provided to the MS and a parameter of a radio communication with the MS, including restoration of full services to an MS whose power supply charge level has been restored.

Abstract: A method and apparatus for creating a semi-active state that reduces channel establishment delay. A communication channel between a mobile station (402) and a radio access network (RAN) (404). The communication channel has a semi-active state between the mobile station and the RAN by preassigning at least one resource to identify the communication channel. In To determine whether the channel is to be made active, the preassigned resource is monitor. When resource indicates that data is to be sent, the channel is converted from the semi-active state to an active state. Data is then transmitted over the communication channel in the active state.

A processor module receives the navigation instruction and language translation instruction, obtains obtaining navigation information based on the navigation instruction, obtains language translation information from the memory based on the language translation instruction entered by the operator. An output is provided for presenting the navigation information and the language translation information to the operator (e.g. audibly and/or visually).

Abstract: Various embodiments are described for providing a list-based service. One group of embodiments involves receiving a subscription to a list to which multiple list members are associated and then providing a notification when an aggregated state of the list satisfies a condition. The aggregated state of the list is based on at least a portion of the state information that pertains to each of the list members. Another group of embodiments involves sending (603) a subscription to a list to which multiple list members are associated and then receiving (605) a notification when an aggregated state of the list satisfies a condition. List-based services, such as presence, can benefit from notifications that are based on a list's aggregated state satisfying some condition.

Abstract: At least one condition concerning a first user (102) within a communication network is obtained. Presence information of a second user (114) within the communication network is determined based upon the at least one condition of the first user (102). The presence information of the second user is then projected to the first user (102).

Abstract: To address the need for a dispatch mobile (303, 305, 307) to more quickly make a call, in the preferred embodiment of the present invention those remote units operating in a dispatch mode (303, 305, 307) will receive a first slot cycle, while those remote units not operating in a dispatch mode (302, 304, 306, 308) 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 (303, 305, 307) 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 (303, 305, 307), 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.

Abstract: Various embodiments are described for establishing a group call session serially. After receiving a serial group call request from a remote unit (101), fixed network equipment (FNE) (201) selects a first subset of members (260) from the targeted group (250) 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 (270) 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.

Abstract: 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.

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 (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.

Abstract: A communication system controls access of a mobile station (MS) to a wireless communication network by generating a RAND Token and conveying the RAND Token and associated constraints to the MS prior to a determination by the MS of a need to access the communication network, wherein the RAND Token is used to authenticate the MS and need not be confirmed prior to the access attempt. By providing the MS with a RAND Token that need not be confirmed, as opposed to the prior art where an MS cannot know whether a global random challenge value provided to the MS prior to a determination by the MS of a need to access the communication network is stale and therefore must confirm the global random challenge value before using it, a call may be set up in an expedited fashion.

Abstract: Paging is provided in a communication network, and implemented in a network infrastructure device (101). Multiple flows including a particular flow are assigned to one or more flow groups. Flow groups, including the foregoing flows, are assigned to at least one paging category, wherein the flow groups have a first paging slot. The paging category is transmitted (107) to one or more communication units (103), wherein the communication unit(s) (103) has requested the particular flow.

Abstract: A method and apparatus as provided for aiding in the strategy and tactical planning for emergency response teams by dividing a site into a plurality of locations and making 360° photographs of the site from each location. The site is interrogated at each location to obtain interrogation information of the site. Each of the photographs corresponding to each location and interrogation information for each location is stored on a computer-readable medium. A location of interest is selected and the photograph and interrogation information for the selected location are displayed.

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: A communication system provides separate subscription keys for a non-subscriber version of a broadcast-multicast flow and a subscriber-only version of the flow, thereby controlling who may store or render the flow. In one embodiment, separate subscription keys may be assigned to a same broadcast-multicast flow. The communication system may then switch the keys used to encrypt the flow, or may use different keys to encrypt different copies of the flow, in order to allow at least non-subscribers to view one version of the flow and only subscribers to view another version of the flow. In another embodiment, the communication system may assign a group subscription key to a group of broadcast-multicast flows that is separate from the keys assigned to each individual flow. The group subscription key may then be used to encrypt a non-subscriber version of any broadcast-multicast flow in the group of broadcast-multicast flows.

Abstract: A communication system provides one or more of congestion information and subscriber information to a broadcast applications server when the server receives a request to start a broadcast-multicast service in a coverage area. By providing the one or more of congestion information and subscriber information to the server, the server is able to make an informed, intelligent decision concerning blocking, unblocking, downgrading, or upgrading a broadcast-multicast flow of multiple broadcast-multicast flows requested for delivery to, or currently delivered to, the coverage area via a serving base station, and/or whether to add a new broadcast-multicast flow to the broadcast-multicast flows delivered to the coverage area.
