Abstract:
A method for identifying ephemeral terminations in a packet-based network includes identifying the Radio Network Controller with an RNC indicator in a first level, identifying the one or more ICCs with an ICC indicator in a second level, identifying the one or more PMCs with a PMC indicator in a third level, and identifying the one or more local components with a local component indicator in a fourth level. The first level, second level, third level and fourth level form different portions of the termination identifier. The termination identifier is structured so that the one or more local components identified in the fourth level are associated with the one or more PMCs identified in the third level, and the one or more PMCs identified in the third level are associated with the one or more ICCs identified in the second level and the one or more ICCs identified in the second level are associated with the one or more RNCs identified in the first level.

Abstract:
A method and apparatus for receiving requests for time scheduled media from a client over the Internet and the delivery of such media programs in a specified streaming video format to the client is disclosed. In a first embodiment the client requests the recording of a media program by a delivery device which delivery device identifies in an e-mail message the storage location of the requested program in the delivery system. The client then accesses the delivery system via the Internet using the storage location identity and the delivery system delivers the stored program. In another embodiment the client requests and receives substantially real time delivery of a requested media program.
Abstract:
A method for controlling the flow of information between a UE and a Node B is provided. The UE transmits over a control channel to the Node B a signal requesting to transmit information to the Node B. The UE then receives over a shared channel from the Node B a signal identifying a time at which the UE is permitted to transmit information. Thereafter, the UE transmits at the identified time over a data channel to the Node B a signal containing the information.
Abstract:
Methods and apparatus for estimating mobile station location in a wireless communication system. At initiation of a call or a page response, a mobile station of the system sends an access request signal to a primary base station. The primary base station responds with an access acknowledgment which may be intentionally delayed such that the mobile station increases its transmit power level. The primary base station then transmits a channel assignment message to the mobile station. The mobile station responds by transmitting a location signal in the form of a known user-specific traffic preamble at the higher transmit power level. The primary base station intentionally delays sending an acknowledgment of the preamble, such that the mobile station transmits the preamble for a longer period of time than it would otherwise. This additional transmission time allows the preamble to be detected accurately in the primary base station as well as in a number of other surrounding base stations in a manner suitable for generating path delay measurements. A primary location processor associated with the primary base station uses the path delay measurements from the primary and surrounding base stations to generate an estimate of mobile location. The mobile location estimation may be provided during an on-going call by the primary base station sending a fake handoff message to the mobile station directing it to handoff to the same base station and traffic channel but with a different power level and preamble length, or by the primary base station sending a predetermined location probe message directing the mobile station to transmit the traffic preamble with a desired power level and preamble length.
Abstract:
A method and system for interworking between communications equipment based on different protocols allows communications service providers to use more than one technology in their networks. For example, Mobile Application Part (MAP) messages of TIA-41 are interworked to corresponding messages of the Global System for Mobile Communication (GSM), and GSM MAP messages are interworked to corresponding TIA-41 MAP messages. An inter technology bridge translates location and routing messages between, for example, an originating mobile switching center (MSC) based on a first technology (e.g., TIA-41 or GSM) and a home location register (HLR) based on a second technology (e.g., GSM or TIA-41). The ITB may include one or more databases for storing information useful for generating attributes or parameters required in an output message that cannot be directly generated from information supplied in an associated input message.
Abstract:
A communication system includes a base station and a plurality of remote stations wirelessly communicating with the base station. The base station determines a respective RF quality for each remote station. In response to a request for RF resources from a given remote station, the base station determines whether admission of the given remote station would exceed an RF power budget threshold. If the RF power budget threshold would not be exceeded, the RF quality is compared to a first quality threshold to determine whether to allocate the requested RF resource to the given remote station. Otherwise, the RF quality is compared to a second quality threshold more stringent than the first quality threshold to determine whether to allocate the RF resource to the given remote station. The base station may further determine whether to allocate requested RF resources on the basis of a priority of the requested resources.
