20080268853 | METHOD OF SHARING MOBILE UNIT STATE INFORMATION BETWEEN BASE STATION ROUTERS - The present invention provides a method of operating a first base station router. The method may include transmitting state information associated with at least one inactive mobile unit to at least one second base station router. The state information is usable to initiate an active session with the at least one inactive mobile unit. The first base station router retains the state information for initiating an active session with the at least one inactive mobile unit and the least one second base station router is capable of initiating an active session with the at least one inactive mobile unit based on the state information when the state information is unavailable to the first base station router | 10-30-2008 |
20090111460 | METHOD OF PROVIDING USER-DETECTABLE FEEDBACK INDICATING CHANNEL CONDITIONS - The present invention provides a method for implementation in a first mobile unit that supports an air interface with a network element. The method includes determining, while the first mobile unit is participating in a call, that at least one channel associated with the air interface is unable to support voice transmission. The method also includes rendering a first user-detectable signal in response to determining that said at least one channel is unable to support voice transmission. | 04-30-2009 |
20090111499 | METHOD OF MODIFYING PILOT POWER FOR A HOME BASE STATION ROUTER BASED ON USER DEMAND - The present invention provides a method implemented in a base station router. One embodiment of the method includes determining a transmission power for a pilot signal transmitted by the base station router. The transmission power being determined based upon a number of mobile units that are camped on the base station router. Another embodiment of the method includes deploying the first base station router in a physical structure and estimating the dimensions of the physical structure based on a statistical representation of at least one handover attempt associated with the first base station router. Estimation of the dimensions of the physical structure occurs in response to deployment of the first base station router in the physical structure. | 04-30-2009 |
20090124235 | METHOD OF CONFIRMING AUTHORIZED MICROCELL BASE STATION USE - An exemplary method of confirming authorized use of a microcell base station includes determining that the microcell base station has made a connection with a mobile station. A determination is made whether the mobile station subsequently establishes a connection with a selected macrocell base station. Whether the mobile station successfully makes the connection with the selected macrocell base station is used as an indication of authorized use of the microcell base station. | 05-14-2009 |
20090138623 | Method and Apparatus for Delegation of Secure Operating Mode Access Privilege from Processor to Peripheral - In a processing system comprising a processor and a plurality of peripherals coupled to the processor, access privileges of a secure operating mode of the processor are delegated to at least a given one of the peripherals. The given peripheral is configured to store, in a secure portion of that peripheral, state information indicative of the processor being in a secure operating mode. The given peripheral is further configured to utilize the stored state information to allow the given peripheral to access at least one resource that is accessible to the processor in the secure operating mode but is not otherwise accessible to the given peripheral. The processing system may comprise, for example, a system on a chip, wherein the processor and peripherals are combined into a single integrated circuit. | 05-28-2009 |
20090172416 | Storage and Retrieval of Encrypted Data Blocks with In-Line Message Authentication Codes - Techniques are disclosed for in-line storage of message authentication codes with respective encrypted data blocks. In one aspect, a given data block is encrypted and a message authentication code is generated for the encrypted data block. A target address is determined for storage of the encrypted data block in a memory. The target address is then modified to permit in-line storage of the message authentication code with the encrypted data block in the memory, and the encrypted data block and the message authentication code are transferred to the memory for storage at the modified address. Illustrative embodiments of the techniques advantageously facilitate secure off-chip storage of data in a processing system. | 07-02-2009 |
20090176513 | METHOD OF SIGNALING-FREE IDLE MODE MOBILITY FOR AN INTEGRATED 3GPP AND 3GPP2 NETWORK - The present invention provides a method of operating a paging controller in a wireless communication system including a first network that operates according to a first radio access technology and a second network that operates according to a second radio access technology. The first network includes a first control plane entity and the second network includes a second control plane entity. The method includes providing, to at least one first base station in the first network, a request to transmit a page to a first tracking area associated with the mobile unit. The first tracking area is defined in the first network. The method also includes providing, via an interface between the first control plane entity and the second control plane entity, a request to transmit the page to a second tracking area associated with the mobile unit. The second tracking area is defined in the second network. | 07-09-2009 |
20090303963 | Method for providing seamless transition between networks following different protocols - Example embodiments provide methods for handling the transition of a mobile device from a first network to a second network, the second network operating according to a different communications protocol from the first network. One example embodiment includes terminating forwarding of the data packets from the first network to the mobile device; rebuilding headers of unforwarded data packets at the first network; and sending the rebuilt data packets from the first network to the second network. Another example embodiment includes resetting a header compression state at the second network; receiving unforwarded data packets from the first network at the second network, the unforwarded data packets being data packets the first network had not yet forwarded to the mobile device; and sending the unforwarded data packets from the second network to the mobile device. | 12-10-2009 |
