Problems solved by technology

[0013] However, the inventors of the present invention found that when the above method is used for state transition, the base station cannot accurately know the time point when the terminal state transition takes effect, so for a period of time the terminal and the base station have inconsistent judgments on the UE state, such as figure 1 From point A to point B, that is, during the period from the successful terminal state transfer to the base station correctly receiving the E-RUCCH sent by the terminal, the base station may continue to schedule the terminal. At this time, the base station uses the old format to transmit HS- DSCH and E-DCH, however, the terminal uses the new HS-DSCH and E-DCH format, resulting in data error transmission
[0014] Similarly, the state transition from CELL-FACH to CELL-DCH also has this problem

Embodiment Construction

[0040] Embodiments of the present invention provide a state transition method, system, and device in an HSPA+ network. After obtaining the new E-RNTI allocated by the base station for the terminal after the state transition, the RNC sends the activation time point to the base station, so that the base station and The terminal can perform state transfer at the same time, thereby preventing the base station from scheduling the terminal in a wrong way during the period from when the terminal state transfer is successful to when the base station correctly receives the E-RUCCH sent by the terminal, thereby improving the accuracy of data transmission.

[0041] Such as figure 2 As shown, the state transfer method in the HSPA+ network provided by the embodiment of the present invention includes:

[0042] Step S201, receiving the message carrying the activation time point sent by the RNC;

[0043] Step S202 , after determining that a new radio network temporary identifier E-RNTI has ...

Abstract

The invention discloses a state transfer method, system and device in an HSPA+ network, and relates to communication technology. After obtaining a new E-RNTI assigned by a base station for the terminal after state transfer, the RNC sends the activation time point to the base station. This enables the base station and the terminal to perform state transfer at the same time, thereby preventing the base station from scheduling the terminal in a wrong way during the period from when the terminal state transfer is successful to when the base station correctly receives the E-RUCCH sent by the terminal, thereby improving the accuracy of data transmission.

Description

technical field [0001] The invention relates to communication technology, in particular to a state transfer method, system and device in an HSPA+ network. Background technique [0002] At present, in the HSPA+ (High Speed ​​Downlink Packet Access, high-speed downlink packet access technology) network, due to reasons such as service rate changes, the CELL-FACH (Forward Access Channel, forward access channel) enhanced state and A state transition between CELL-DCH (Dedicated Channel, dedicated channel) states, for example, a typical scenario of a state transition process from CELL-DCH to CELL-FACH is a rate change trigger. State transition needs to be realized through air interface reconfiguration or cell update process, using dedicated RRC (Radio Resource Control, radio resource control protocol) messages through the Uu interface (the interface between UE (User Equipment) and UTRAN (UMTS Terrestrial Radio Access Network)) To notify the terminal of the transfer status. After t...
