Abstract: A method and apparatus for providing an efficient dormant mode for push-to-talk communication devices (102, 104, 106) in a group communication network (100) provides for determining whether the net has been inactive for a predetermined first time period and, if so, causing each member of the net to enter a control-hold mode, wherein each member of the net maintains its dedicated traffic channel. The method further includes the steps of determining whether each member of the net has been in the control-hold mode for a predetermined second time period and, if so, causing each member of the net to enter a dormant mode, wherein each member of the net releases its dedicated traffic channel. The method and apparatus further provides for causing each member of the net to cache its service configuration state before entering the dormant mode.

Abstract: A method and apparatus for reducing dormand-wakeup latency in a group communication network (100) provides for a significant reduction in the actual total dormant-wakeup time and the PTT{XE"PTT"} latency perceived by the talker through caching the network-initiated wakeup tiggers destined for target listeners, and delivering a wakeup trigger to a target mobile station (104, 1o6, 108) as soon as the target mobile station has re-established its traffic channel.

Abstract: A method and apparatus provides for delivering information to an idle mobile station in a group communication network (100) includes delivering the information to the mobile station in special form, e.g., short data burst (SDB) form, if the information is smaller than a predetermined size limit. In one embodiment, the method and apparatus provides for encapsulating the information inside a frame, forwarding the frame to a server (110) for delivery to the mobile station (102, 104, 106), and causing the server (110) to extract the information from the frame and deliver the information to the mobile station on a forward common channel. In one embodiment, the method and apparatus provides for receiving information for delivery to the mobile station (102, 104, 106), the information being tagged for delivery on a forward common channel, and delivering the information to the mobile station (102, 104, 106) on the forward common channel. In one aspect, the method delivers the information when the mobile station (102, 104, 106) is in idle state with no traffic channel.

Abstract: An embodiment is directed to displaying information to a user of a communications device. The communications device receives a query including a social parameter, a temporal parameter and a spatial parameter relative to the user that are indicative of a desired visual representation of a set of data objects. The communications device determines degrees to which the social, temporal and spatial parameters of the query are related to each of the set of data objects in social, temporal and spatial dimensions, respectively. The communications device displaying a first visual representation of at least a portion of the set of data objects to the user based on whether the determined degrees of relation in the social dimension, temporal dimension and spatial dimension satisfy the respective parameters of the query.

Abstract: Methods and apparatus to provide a virtual network interface. In an aspect, a method includes receiving a request to access content on a Non-IP network, wherein the request comprises an IP address and a quality of service (QoS) profile associated with the content, mapping the IP address and the QoS profile into a Non-IP network content identifier, and obtaining the content from the Non-IP network based on the Non-IP network content identifier. In an aspect, an apparatus includes an application interface configured to receive a request to access content on a Non-IP network, wherein the request comprises an IP address and a QoS profile associated with the content, mapping logic configured to map the IP address and the QoS profile into a Non-IP network content identifier, and processing logic configured to obtain the content from the Non-IP network based on the Non-IP network content identifier.

Abstract: A service for Public Safety (PS) and Law Enforcement (LE) users on commer cial wireless networks which assure them access to packet data services. The service request is application based. The applications that are for officia l use, by the PS/LE users, could have a reserved priority level associated w ith them. The reserved priority level could be higher than a normal commerci al user. The network could use the priority to distinguish users, and dynami cally allocate and optimize network resources. The network could use priorit y level information to perform access, admission, and congestion control. Th e PS/LE user could use the official applications while on duty and un-offici al ones while off duty, thus, additionally freeing up network resources. The PS/LE users could then use advanced commercial packet data services, withou t the need for a private network, while at the same time making it feasible for commercial networks.

Abstract: A method and apparatus for adding a member to an active call in a group communication network provides for receiving a member list from a user and sending a request to a server to add the member list to the active group call. The method and apparatus further provides for announcing each member in the member list that they are being added to the group call, receiving acknowledgement from a member who wishes to participate in the group call, and forwarding media to the member. The method and apparatus also provides for a significant reduction in the actual total dormancy wakeup time and latency by exchanging group call signaling even when mobiles are dormant and no traffic channel is active.
