  • the present invention relates to the field of communications, and in particular, to a method for establishing a fast reconnection.
  • BACKGROUND In a UMB system, when data transmission is required between an access terminal in an idle state and an access network, first, a connection is established with the access network and various parameters are negotiated before data can be transmitted. As shown in Figure 1:
  • the access terminal is in an idle state.
  • the access terminal sends a "routing open request” message to the access network.
  • S106 The access network returns a response message "Route Open Accept” to the access terminal, and carries a UATI (Unicast Access Terminal Identifier) assigned to the access terminal.
  • UATI Unicast Access Terminal Identifier
  • the access terminal After receiving the UATI, the access terminal sends a "UATI Assignment Complete" message to the access network.
  • the access network sends a “configuration start” message to the access terminal, and starts negotiating related parameters.
  • the access terminal and the access network perform session negotiation.
  • the access network sends a “configuration complete” message to the access terminal, indicating that the session negotiation is completed.
  • S116. Perform data transmission between the access terminal and the access network. After the data transmission between the access terminal and the access network is completed, the connection needs to be closed, and the access terminal returns to the idle state. as shown in picture 2:
  • S204 The data transmission is completed, and the access terminal sends a “connection closed” message to the access network.
  • the access terminal and the access network respectively release respective channel resources.
  • the access terminal returns to an idle state.
  • the method for establishing and releasing the connection has the disadvantage that the process of establishing a connection between the access terminal and the access network is complicated, and the signaling interaction is many, resulting in a long connection establishment time, and the reconnection process after each connection release is repeated.
  • PTT Push To Talk
  • the connection between the access terminal and the access network is very frequent, and each time the connection is established, the duration is short. Release, and require the connection to be established quickly.
  • Another example is the web browsing service.
  • a method for quickly re-establishing a connection includes the following steps:
  • Step S302 in the case that the access terminal and the access network can release the connection, the access terminal and the access network do not release the channel resources, and start a timer to start timing respectively; Step S304, before the predetermined duration of the timer arrives When the access network receives the reactivation request from the access terminal, the access terminal and the access network respectively stop the respective timers and use the unreleased channel resources for data transmission; When the access network does not receive the reactivation request of the access terminal, the access terminal and the access network release the channel resources.
  • step S302 after the data transmission between the access terminal and the access network is completed, the access terminal sends a connection close message to the access network, and the connection close message carries a predetermined duration of the timer.
  • step S304 after the access terminal sends a reactivation request to the access network, the timer on the access terminal side is stopped.
  • the access network feeds back the reactivation accept message to the access terminal, and stops the timer on the access network side.
  • the fast reconnection establishing method of the present invention can be applied to a super mobile broadband system.
  • the fast reconnection establishment method of the present invention requires complete construction except for the first connection establishment.

  • FIG. 5 is a schematic diagram of a fast reconnection establishment process in the PTT service of the present invention.
  • FIG. 3 is a flow chart of a method for establishing a fast reconnection according to the present invention. As shown in FIG.
  • the method includes: Step S302: When an access terminal and an access network are capable of releasing a connection, neither the access terminal nor the access network release channel resources, and simultaneously start a timer to start timing; Step S304, before the access network receives the reactivation request from the access terminal before the predetermined time duration of the timer arrives, the access terminal and the access network respectively stop the respective timers and use the unreleased channel resources. In the case where the timer arrives at a timing and the access network does not receive a reactivation request from the access terminal, the access terminal and the access network release the channel resources.
  • step S302 after the data transmission between the access terminal and the access network is completed, the access terminal sends a connection close message to the access network, where the connection close message carries a predetermined duration of the timer.
  • step S304 after the access terminal sends a reactivation request to the access network, the timer on the access terminal side stops counting. When receiving the reactivation request from the access terminal, the access network feeds back the reactivation accept message to the access terminal, and stops the timer on the access network side.
  • 4 is a schematic diagram of a fast reconnection establishment process of the present invention. As shown in Figure 4:
  • the access terminal sends a "connection closed” message to the access network, the message carries the timer Tclose duration, and starts the timer Tclose; the access network receives the "connection closed” message, starts the timer Tclose.
  • the access terminal needs to transmit data before the Tclose timeout, send a "reactivation request” message to the access network, and stop the timer Tclose.
  • the access network After receiving the "Reactivation Request” message, the access network returns a "Reactivate Accept” message to the access terminal, and stops the timer Tclose. S410.
  • the access terminal and the access network use unreleased channel resources for data transmission.
  • FIG. 5 shows the flow of a quick reconnection between an access terminal and an access network in a PTT service. As shown in Figure 5, the process includes:
  • the access terminal and the access network have established a connection, allocated channel resources, and are performing data transmission.
  • the access terminal starts the timer Tclose.
  • the access network receives the "connection closed” message sent by the access terminal, and starts the timer Tclosc.
  • S510 The timer Tclose of the access terminal times out. If the timer expires, go to S514. S512, whether the user presses the PTT button, if not pressed, go to S510; if pressed, turn

  • the access terminal sends a "reactivation request" message to the access network.
  • the access network receives the "Reactivation Request” message, and returns a "Reactivate Accept” message to the access terminal.

Abstract

L'invention porte sur un procédé d'établissement de reconnexion rapide, qui comprend : une première étape à laquelle, dans le cas où un terminal d'accès ou un réseau d'accès peuvent libérer la connexion, le terminal d'accès et le réseau d'accès ne libèrent pas tous deux la ressource de canal, en même temps ils lancent séparément un temporisateur pour mesurer le temps ; une seconde étape à laquelle, avant d'atteindre l'expiration du temporisateur, lorsque le réseau d'accès reçoit la requête de réactivation provenant du terminal d'accès, le terminal d'accès et le réseau d'accès arrêtent séparément le temporisateur respectif, et transmettent les données à l'aide de la ressource de canal non libérée.
