Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0015] Based on the existing C.S0024 standard protocol, the present invention supports the function of satellite relay by adding a field to the ACAck message in the standard protocol to notify the AT (Access Terminal) side of the MAC protocol state transition timer duration. At the same time, the duration can be decided or negotiated by AN.

[0016] As shown in FIG. 1, this embodiment takes an HRPD system based on the CDMA standard as an example, and the method specifically includes the following steps:

[0017] 101. The access terminal sends a ConnectionRequest message to the access network.

[0018] 102. The access terminal sends a RouteUpdate message to the access network.

[0019] 103. The access network sends an ACAck message to the terminal. The ACAck message includes an 8-byte TimerATSerup field to notify the access terminal of a TimerATSetup o...

Abstract

The utility model discloses a satellite repeater support method in the high speed grouped data system. The method includes following steps as a. The access terminal sends the access request message and route updating message to the access network; b. The access network returns the confirmed access messages, comprising the timer field parcel which represents the duration. After receiving, the access terminal starts up the timer with the duration. C. The access network transmits the assigned traffic channel messages to the access terminal, while the access terminal sends the pilot frequency + data rate control message to the access network; d. The access network returns the confirmed message for the reversal traffic channel. After receiving, the access terminal closes the timer and sends the traffic channel completion message to the access network. The utility model can support the satellite repeater function between the AN's receiver transmitter and the base station controller; also, the duration can be ascertained and coordinated by AN.

Description

Technical field [0001] The invention relates to a method for supporting satellite relay in an HRPD (High Speed ​​Packet Data) system. Background technique [0002] At present, in the C.S0024 air interface standard protocol of the HRPD system, during the connection establishment process, the large time delay between the BTS (transceiver) and the BSC (base station controller) of the AN (access network) is not considered. Subsequently, the normal connection establishment and handover process cannot be completed in systems such as the existence of satellite relays. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a method for supporting satellite relay in a high-speed packet data system, so that the C.S0024 standard supports the function of satellite relay between BTS and BSC of AN. [0004] In order to solve the above technical problems, the present invention is realized through the following technical solutions: [0005] A...
