  • Patent number: 7672682
    Abstract: In a radio access network, techniques for determining how often an aces terminal in communication with the network is to monitor a channel of the network based on trigger information received from the access terminal that is specific to one or more of the following: a state of the terminal, a state of a premium application, and a user of the terminal. The trigger information includes information about one or more of the following: a power mode of the access terminal, a user profile identification, an activation of a premium application on the terminal, and a terminal of a premium application on the terminal.

  • Patent number: 6904034
    Abstract: The invention provides a method and system for allowing communication between a BSS and SGSN, each having an NS-VC table and utilizing a different mode of communication. For example, a BSS may utilize associating UDP with NSE and IP with NS-VC and the SGSN may utilize associating UDP with NS-VC and IP with NSE. The method and system provides for the construction of an NS-VC table correlating the NS-VC table of the BSS and SGSN. Therefore, the method and system provides for the conversion of a data packet having UDP associated with NS-VC and IP associated with NSE to UDP having association with NSE and IP having association with NS-VC and vice versa. An NS-VC table may be constructed from information provided from a negotiations procedure or normal communications. The constructed NS-VC table allows for communications between the mobile communications architecture and the packet switched architecture, without requiring compatible utilization of UDP and IP.

  • Patent number: 6836475
    Abstract: A shaper 201 and a scheduler 203 are combined to determine a target tree 203 and insert 207 a tag into a data structure, wherein the tag is associated with a packet that has reached the head of line (HOL) of a queue in a packet router. A tag may become an eligible tag and be placed in a set of tags to be searched. Such tags are searched for the smallest tag. A packet associated with the smallest tag is transmitted if the output link is available.

  • Patent number: 6331978
    Abstract: A method for encapsulation of labeled datagrams over serial communications links, and a method for extracting the datagrams on the receiving end of the link. The encapsulation method includes adding a label and a label error correction to the front of a datagram, the label error correction being derived using the label and adding a cyclic redundancy check at a trailing end of the datagram, the cyclic redundancy check being derived using the datagram. The end of a packet encapsulating the datagram with a label, a label error correction field and a cyclic redundancy check field is identified by analyzing incoming bits for a packet until a pattern of bits is detected that matches a number of previous bits of the packet coded with a predetermined coding formula and identifying the end of the packet based upon the detection of the match and the predetermined coding formula.

  • Patent number: 6327274
    Abstract: A method, a system, and an article of manufacture for measuring a relative skew between clocks in a packet based communication network. The method utilizes the timestamps available in packets sent from a sender to a receiver, as well as the times at which the receiver receives such packets. Such timestamps can be incorporated in packets, or in a separate protocol.
