  • Publication number: 20080151770
    Abstract: The method provides for establishing a communication session in a hierarchical communication system between a source party and at least one destination party. Hierarchical communication systems generally have communication nodes at different levels of hierarchy. In one embodiment, connection information for the communication session is stored if establishing the communication session is blocked at a node as a result of a blocking condition at the blocking node. Establishment of the communication session is initiated based on the stored connection information if the blocking condition no longer exists at the blocking node.

  • Publication number: 20070268959
    Abstract: At least a portion of a total spectrum bandwidth of a wireless system may be allocated to each of a plurality of users by assigning at least one unique spreading code to each of the plurality of users. At least two of the plurality of users may have different spectrum capabilities and may transmit simultaneously. Each of the assigned spreading codes may have a different code length. The number and/or the code length of the spreading codes assigned to each user may be indicative of a portion of the total spectrum bandwidth allocated to each user.

  • Publication number: 20070270158
    Abstract: The present invention provides a method and an apparatus for enabling at least one location-based service between an originating party and a destination party on a wireless network. The method comprises integrating access to the at least one location-based service substantially simultaneously with an offering of at least one multi-media service for voice and data over the wireless network. The method further comprises initiating the at least one location-based service in response to receiving an inquiry from the originating party for determining a network location of a target mobile terminal associated with the destination party. A service platform may generate substantially simultaneously multi-media services including a location-based service based on location information of a destination user in a wireless network, such as a mobile data network.

  • Publication number: 20070207827
    Abstract: The present invention provides a method and an apparatus for controlling transmission power of a wireless unit. The method includes providing a power control in a reverse link to a network that transmits data on a traffic channel in a bursty manner based on a performance metric of a channel with continuous transmission of other data than on the traffic channel. To provide a power control in a reverse link of a spread-spectrum wireless data network a method and an apparatus are provided for combining performance of a quality of service from at least one of a first quality feedback channel and a second quality feedback channel with that of a pilot channel and providing an outer-loop power control in said reverse link for a wireless communication on a traffic channel based on said combined performance of the quality of service to control transmission power of a wireless unit.

  • Publication number: 20070147331
    Abstract: In one embodiment of a method of managing transmission delay in a wireless communication system, a length of time over which a mobile station is permitted to re-transmit a packet or portion of a packet over a channel is controlled such that the length of time depends on at least one of a position of the mobile station, a temporal fading characteristic of the mobile station, and a radio frequency characteristic of the channel.

  • Publication number: 20070133445
    Abstract: The present invention provides a method and an apparatus for a wireless communication between a base station and at least one mobile station. The method includes receiving a request for a data rate from the mobile station on a reverse link channel to the base station. The method further includes, in response to the request, skipping a first slot after a delay for a portion of a slot on a forward link transmission before transmitting a data packet in a second slot. By beginning the forward link transmission at the start of the second slot, for example, a software module may cause the base station to skip a slot immediately after the half slot delay. This additional delay of one slot or a portion of the slot may expand radius of a cell for a wireless communication between the base station and the mobile station in a relatively high-speed wireless data network.

  • Publication number: 20070077938
    Abstract: The present invention provides a method and an apparatus for controlling a radio frequency resource between a first and a second wireless unit and a base station to provide overload control of the radio frequency resource based on an estimate thereof. For example, when feedback information is unavailable for the radio frequency resource at the base station. The method includes estimating the radio frequency resource used by the first and second wireless units in a wireless data network. The method further includes providing an overload control at the base station based on the estimated radio frequency resource. Based on this estimated radio frequency resource, a command may be issued by the base station on a reverse link. For example, a rise over thermal resource may be estimated to issue a rate control command to a wireless unit. By providing a desired timely rate control command on the reverse link, the base station may control a data rate of the wireless unit, maximizing throughput of the reverse link.
