  • Patent number: 7043253
    Abstract: A system, method and node for supporting PDSN load balancing in a CDMA2000 network. A mobile node (MN) sends an origination message to a BSC/PCF that sends a registration request indicating that it supports load balancing according to the invention to the manager part of a PDSN that selects an agent to take care of the connection and redirects the request to it. The agent then validates the request and sends a reply to the BSC/PCF indicating that the initial request has been redirected. The reply also comprises the IP address of the agent. The BSC/PCF then sets up an A10 connection with the agent, and the MN and the agent negotiate a PPP session. There is further a method of setting up a connection between two entities, via a third entity.

  • Patent number: 6771623
    Abstract: The present invention relates to data communications in packet switched networks and more specifically to the mobility of terminals in networks implementing the Mobile Internet Protocol (MIP). In the method according to the present invention each Home Agent will store locally the load information from other Home Agents and will exchange load information with the other Home Agents. The Mobile Node first attempts to register with its primary Home Agent. This registration is not completed due to e.g. failure of the primary Home Agent or where the network chooses to register with another Home Agent which has a lower load than the primary Home Agent. The Mobile Node then attempts to register with a second, alternate, Home Agent. If the alternate Home Agent accepts the request then the Mobile Node is able to access MIP services through the alternate Home Agent.

  • Patent number: 6745012
    Abstract: A method and system for performing adaptive compression in a wireless communication network includes monitoring a link quality of a signal transmitted via an air interface using, for example, a telecommunications node. Next, it is determined whether the link quality deteriorates below a first link quality threshold. A compressor associated with the transmitted signal is disabled in response to a determination that the link quality has deteriorated below the first link quality threshold.

  • Publication number: 20030117983
    Abstract: A GPRS Support Node (GGSN) has a plurality of user plane (data session) processing units (GTP-Us) for handling data sessions for Mobile Stations (MSs), a plurality of controlling units (GTP-C/s) for controlling the data sessions payloads, and a master data session control unit (GTP-C/m) dispatching data sessions requests to GTP-C/s. When a GTP-U goes down, the GTP-C/m detects the failure. If no spare GTP-U is available, the GTP-C/m removes internal connections related to the failed data sessions, and instructs all the GTP-C/s that controlled data sessions lost on the failed GTP-U to delete the PDP contexts of those sessions, and requests a Route update from the Routing Engine (RE). If a spare GTP-U is available, the GTP-C/m activates the spare GTP-U, and requests every GTP-C/s that controlled data sessions on the failed GTP-U to rebuild these sessions on the spare GTP-U unit. Following completion of the rebuild, it requests a Route update from the RE.

  • Publication number: 20030117948
    Abstract: A GPRS Support Node (GGSN) has a plurality of slave data session control units (GTP-C/s) for controlling data sessions for Mobile Stations (MSs), a plurality of data sessions payload units (GTP-Us) for supporting routing of data sessions payloads, and a master data session control unit (GTP-C/m) dispatching data sessions requests to GTP-C/s. When a GTP-C/s goes down, the GTP-C/m detects the failure, closes data sessions of the failed GTP-C/s and their corresponding accounting sessions. If a spare control unit is available, the GTP-C/m detects and activates the spare unit with the role and IP address of the failed GTP-C/s. When the GTP-C/m goes down, all the control units are notified, and the least loaded unit is elected for replacing the GTP-C/m. The elected unit is a spare, non-utilized, GTP-C, or one of the slave GTP-C/s, which is activated as the GTP-C/m by rebuilding a GTP-C/m database with information received from remaining GTP-C/s.
