  • Patent number: 7957736
    Abstract: In conventional cellular systems, the identifier of network elements (SGSN) allocating a temporary identity (TLLI) to a mobile station (MS) can be derived from the identities of the cells they serve. In the future, this assumption may no longer be valid. One paging area could be handled by several network elements, such as SGSN nodes, or one network element could serve many paging areas. When the mobile station changes its paging area, the new supporting network element may have trouble in determining the old supporting network element on the basis of the paging area identifier. It is also possible for two supporting network elements to allocate the same TLLI to two different mobile stations. Therefore the network element (SGSN, BSC, RNC) allocating a temporary identity (TLLI) to a mobile station (MS) should incorporate at least part of its own identifier (NEI) into the temporary identity (TLLI).

  • Patent number: 7953450
    Abstract: Methods and apparatus for providing restrictions on long distance calls from wireless communication devices. The wireless devices are preferably combined voice and data communication devices. In one illustrative example, each wireless device receives and stores long distance call restriction information which is pushed from a private computer network through the wireless network. During typical operation, a wireless device determines whether call attempts from the wireless device are restricted by the long distance call restriction information. If a call attempt is restricted by the long distance call restriction information, the wireless device restricts the call attempt from the wireless device and provides for a call restriction alert indication (e.g. an alert tone or visual text). If a call attempt is not restricted by the long distance call restriction information, the wireless device allows the call attempt from the wireless device.

  • Patent number: 7916625
    Abstract: Messages transmitted between a receiver and a transmitter are used to maximize a communication data rate. In particular, a multicarrier modulation system uses messages that are sent from the receiver to the transmitter to exchange one or more sets of optimized communication parameters. The transmitter then stores these communication parameters and when transmitting to that particular receiver, the transmitter utilizes the stored parameters in an effort to maximize the data rate to that receiver. Likewise, when the receiver receives packets from that particular transmitter, the receiver can utilize the stored communication parameters for reception.

  • Patent number: 7869794
    Abstract: A system is provided for managing timely delivery of electronic messages, such as short message service (SMS) messages sent by the short message peer to peer (SMPP) protocol. In particular, the system determines an expected delay for the delivery of electronic messages, so that a sender can avoid sending messages when they will take an excessive amount of time to deliver. In one embodiment, a sender of electronic messages, such as a news service provider, sends a session initiation protocol (SIP) “subscribe” message to a delay manager. The delay manager determines when the expected delay of message delivery at a bulk message gateway falls below a threshold delay. When the expected delay falls below the threshold, the delay manager informs the sender, and the sender may create and send an electronic message.
