Embodiment 1

[0072] In this embodiment, the network side sends the content of the SIB11 / SIB12 through a point-to-point message, thereby reducing the delay caused by the user terminal waiting to read the SIB11 / SIB12 on the broadcast channel, and the point-to-point message is passed The dedicated channel is issued to the user terminal. The specific implementation process of this embodiment is shown in Figure 3, and specifically includes the following processing steps:

[0073] Step 21: the network side, that is, the UTRAN (Radio Access Network), sends a reconfiguration signaling to the user terminal, and the signaling is used to indicate that the terminal needs to enter the CELL_FACH state after executing the reconfiguration command;

[0074] Step 22: After receiving the RRC signaling message, the terminal performs a pre-cell selection operation to determine a cell that meets the cell selection criteria;

[0075] Since a neighboring cell list information synchronized with the network side is...

Embodiment 2

[0092] In this embodiment, specifically, the SIB11 / SIB12 message that the user terminal needs to obtain is encapsulated in an RRC signaling message, and is delivered to the user terminal through a common control channel (CCCH);

[0093] The specific implementation process of this embodiment is as shown in Figure 4, and specifically includes the following steps:

[0094] Step 31: the network side, that is, UTRAN, sends a reconfiguration command to the user terminal, indicating that the terminal needs to enter the common channel (ie, the CELL_FACH state);

[0095] The RRC signaling message also includes new configuration information used by the user terminal after entering the common channel;

[0096] Step 32: After receiving the reconfiguration command, the user terminal performs a reconfiguration operation, and enters the CELL_FACH state according to the RRC state information in the reconfiguration command (that is, the indication information that the terminal needs to enter a...

Embodiment 3

[0109] The scenario where this embodiment is applied is: the user terminal is originally in the Cell_Fach state, and the reconfiguration command indicates that the terminal is still in the Cell_Fach state after performing reconfiguration; the user terminal needs to initiate a cell update process in a newly selected cell (mapped from RACH to CCCH above) and reconfiguration signaling response signaling (mapped from RACH to DCCH);

[0110] In this embodiment, the specific processing process is similar to the processing process shown in Figure 4 in Embodiment 2, specifically as shown in Figure 5, only the application scenarios of this embodiment and Embodiment 2 are different. The terminal undergoes a state transition during the reconfiguration process, from the Cell_DCH state to the Cell_FACH state. In Embodiment 3, the terminal is in the Cell_FACH state before the reconfiguration process, and is still in the Cell_FACH state after reconfiguration, so it will not be detailed here. ...

Abstract

The utility model relates to a method and a system for the user terminal obtaining systematic broadcasting messages and information, mainly comprising the following steps: firstly, the user terminal transmit the indication information of required systematic broadcasting messages and information to the network side, secondly, the network side determine the systematic broadcasting messages and information to be transmitted to the user terminal after receiving the indication information and then load the systematic broadcasting messages and information in the point-to-point message and transmit to the user terminal. Thus, the utility model can reduce the time delay generated from the process of the user terminal obtaining the systematic broadcasting messages and information, thus the systematic broadcasting messages and information required by the user terminal can be obtained conveniently and immediately; therefore, the problem of long time delay generated by receiving the systematic broadcasting messages and information when the user terminal is in the process of converting the channel type and entering again the serving area can be solved.

Description

technical field [0001] The present invention relates to the technical field of wireless network communication, in particular to a channel type conversion processing technology in a wireless communication network. Background technique [0002] In a wireless communication network, the network side broadcasts system broadcast messages on a system broadcast control channel at a fixed period, so that terminals can receive these system messages in a timely manner and respond to these messages in a timely manner. [0003] The following will describe the channel type conversion process of the user terminal in the prior art. [0004] In a wireless communication network, when there is no traffic between a user terminal in the CELL_DCH (Cell Dedicated Channel) state and the network for a certain period of time, the RNC (Radio Network Controller) will send an RRC (Radio Resource Control) message, such as a physical A layer reconfiguration message or a radio bearer reconfiguration messa...
