Abstract:

In a wireless communication system ( ) having a plurality of communication cells ( ), and a plurality of mobile stations ( ) operating within selected ones of the multiple communication cells ( ), a method and an apparatus for selecting those communication cells ( ). Within each communication cell ( ), a base station ( ) transmits a message directed to the mobile stations ( ), and detects a response indicator in the selected ones of the plurality of communication cells ( ). The message may be a broadcast page message transmitted by the base station ( ). The response indicator may be an impulse radio-frequency energy transmission generated by the plurality of mobile stations ( ) operating within the selected ones of the plurality of communication cells ( ). The base station ( ) may detect the impulse radio-frequency energy transmission on a control channel or during a predetermined time window period ( ) following transmission of the message.

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04Q 720

US Classification:

455442, 455437

Abstract:

To address the need for an apparatus and method for CDMA-dispatch soft handoff, the present invention enables mobile-initiated soft handoff for dispatch calls. A mobile station ( ) in a dispatch call establishes an individual inbound link ( ) with the serving base site ( ). When the mobile station determines that a handoff with an adjacent site ( ) is needed, the mobile station uses its individual inbound link to request a soft handoff with the adjacent base site. After notifying the adjacent base site, the serving base site then transmits the handoff information to the mobile station to enable the mobile station to begin a soft handoff with the adjacent site.

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04Q 738

US Classification:

455519, 4554521

Abstract:

To address the need for a base site and method for quickly establishing a CDMA dispatch call, the present invention provides for signaling mobile stations (e. g. , ) to inform them of the call and then starting the dispatch call without waiting for the call participants to request their inbound links. The dispatch call is first transmitted by base sites (e. g. , ) of all the service coverage areas (e. g. , ) that may have call participants, and then discontinued at those base sites where no inbound link requests are received within a period of time. Thus, the dispatch call is established while âcall setupâ effectively continues.

Abstract:

To address the need for an apparatus and method for CDMA-dispatch soft handoff, the present invention enables base-initiated soft handoff for dispatch calls. A mobile station () in a dispatch call establishes an individual inbound link () with the serving base site (). The serving base site and one or more adjacent base sites (e. g. , and ) determine the signal quality of the inbound link transmissions of the mobile station. The adjacent base site with the highest received inbound link signal quality is selected as the target soft handoff site. The serving base site then transmits the handoff information to enable the mobile station to begin a soft handoff with the target site.

Abstract:

A dispatch server () is provided in a packet based dispatch radio network to serve as coordinator and arbitrator for dispatch group calls. Participants in a group call transmit internet protocol (IP) voice packets to the server in unicast fashion. The server receives voice packets from multiple sources () and implements a prioritization scheme to select one source to pass on to the group via IP multicast. Various prioritization techniques are described.

US Classification:

370331, 455442, 455519

Abstract:

To address the need for an apparatus and method for CDMA-dispatch soft handoff, the present invention provides soft handoff to mobile stations (MSs) () in a dispatch call by sharing soft handoff information with all the MSs in the call at a base site (). When a first MS (e. g. , ) needs to soft handoff, the identity of a soft handoff channel () at an adjacent base site () is shared with all the MSs. Thus, subsequent MSs (e. g. ) that need to soft handoff to that adjacent base site may do so without requesting a soft handoff.

International Classification:

US Classification:

Abstract:

Disclosed are methods that associate “importance” information with chunks of a media presentation. An end-user device or server uses this information to intelligently manage resources when downloading or rendering the media presentation. Many different types of importance information are used. An editor can tag a chunk as important based on the content of the chunk or may give the chunk a rating, or importance can be inferred from download statistics. In some embodiments, the end-user device determines the importance of a chunk based on observations of the behavior of the device's user. The end-user device can send its locally gathered behavioral observations to a server to enhance that server's demographic information. The server can observe its own download behavior to infer importance. The end-user device may choose to either not download, or to download at a low resolution, those chunks deemed to be unimportant, thus saving bandwidth and battery power.
