Cell private channel）State, CELL_FACH（CELL_Forward Access Channel, cell forward access channel）State
And CELL_PCH（CELL_Paging Channel, cell paging channel）State.
Wherein, the essential characteristic of CELL_DCH states is that the special physics letter for transmitting data is assigned in terminal
Road, except the special physical channel of up-downgoing（Dedicated Physical Channel, DPCH）Outside, terminal is also possible to be divided
With physically DSCH Downlink Shared Channel PUSCH（Physical Uplink Shared Channel）And/or PDSCH（Physical
Downlink Shared Channel）, according to UTRAN（Universal Mobile Telecommunications System
Terrestrial Radio Access Network, UMTS land radio access web）Distribution condition, eventually
End can use dedicated transmission channel, up shared transmission channel（Uplink Shared Channel, USCH）, it is descending shared
Transmission channel（High-Speed Downlink Shared Channel, DSCH）, and the combination of these transmission channels.Terminal
During in CELL_DCH states and when being in co-frequency cell junction, radio signal quality can be met desired homogeneous-frequency adjacent-domain
Report network side, network side co-frequency cell configurating terminal corresponding to add activation collection.The essential characteristic of CELL_FACH states
It is that the DPCH connection for being used to transmit data is not present between terminal and UTRAN, terminal will be supervised continuously in down direction
Depending on FACH transmission channels, and public or shared transmission channel can be used in up direction.UTRAN is by the change of system information
Terminal is broadcast to by corresponding schedule information in time on FACH, so that terminal re-reads corresponding system information.
When the terminal in CS domains detects that RUE occurs for SRB2, just switch to non-CELL _ DCH state from CELL_DCH states, eventually
End carries out re-selecting cell operation in non-CELL _ DCH state, and when the operation for carrying out re-selecting cell, to reach certain time also not complete
Into the operation of re-selecting cell, the real call drop of terminal.
Specifically, when terminal retransmit a PDU exceed certain amount when, transmission window reach maximized window when or receive and connect
The sequence number for including mistake that debit sends（Sequence Number）Status PDU（Status protocol data units,
Status Protocol Data Unit）When, terminal initiates RLC Reset processes, i.e., sends a Reset PDU to bottom
（Reset Protocol Data Unit, reset protocol Data Unit）, and start corresponding timer, if advised in timer
In the fixed time, terminal have received to should be in Reset PDU Reset ACK（Acknowledgement character,
Confirm character）PDU, i.e. both RSN（Reset Sequence Number, reset sequence number）When identical, then timer stops
Only, Reset PDU are otherwise resend.Because SRB2 most Reset numbers are 1, so if terminal initiates RLC Reset
Process, and corresponding ACK PDU are not received by within the time as defined in timer, it is determined that detect that RUE occurs for SRB2.
After terminal detects that RUE occurs for SRB2, the operation of re-selecting cell can be carried out as early as possible.This is because, terminal is non-
CELL_DCH states can not carry out the transmission of the mass data similar to call, it is therefore desirable to complete the gravity treatment behaviour of cell as early as possible
Make, to return to CELL_DCH states from non-CELL _ DCH state.
Specifically, the system message that terminal issues according to network side（System Information Block,SIB）Again
Cell is selected, there can be multiple systems message element in system message, it is specific as follows：
SB1、SB2：SIB schedule information；SIB1：NAS（Non Access Stratum, Non-Access Stratum）The system letter of layer

As shown in figure 1, the schematic flow sheet of the method for the re-selecting cell according to the present embodiment.
Step 101, when terminal needs cell reselection, re-selecting cell information is generated according to the cell information of terminal storage.
When terminal detects itself to when RUE occurs, terminal starts cell reselection operation.The purpose of cell reselection is to make terminal
Again it is connected with cell, and recovers the business in CS domains, i.e., terminal needs to rebuild SRB2 and reacquires dedicated channel, that is to say, that
Terminal is set to switch to CELL_DCH states again from non-CELL _ DCH state.Here the cell of terminal gravity treatment may is that and occur
Cell during RUE is identical or different from cell when RUE occurs.
The re-selecting cell information includes terminal and initiates to be connected with cell：Cell ID, cell biasing, adjacent area scrambler and neighbour
Area's pilot tone etc., terminal can just reconnect to cell according to the re-selecting cell information, and how terminal is according to re-selecting cell information
Re-selecting cell is prior art, be will not be repeated here.
Here cell information can be that the gravity treatment that terminal includes in the system message received before needing re-selecting cell is small
The network side cell information issued received or the adjacent area cell information detected before area's information, or terminal, also
It is to say that the cell information is that terminal needs to have stored in the cell information of terminal inner, i.e. cell known to terminal during re-selecting cell
Information.The newest re-selecting cell information received is preferably used in the present embodiment, can so ensure the available of cell information as far as possible
Property.Here recently received re-selecting cell information, refer to terminal detect RUE occurs when time nearest cell
Information.The cell information is stored in terminal.
Step 102, according to re-selecting cell information, initiate to establish with the connection of the cell of gravity treatment.
Terminal initiates the connection with cell, i.e., switchs to CELL_DCH states again from non-CELL _ DCH state, to recover former
The business come.
In the present embodiment, when terminal needs to choose cell foundation connection accordingly again, according to the cell obtained
Information generates re-selecting cell information, and so, terminal may dispense with the time for obtaining re-selecting cell information, so as to accelerate cell weight
Process is selected, the connection with cell is initiated as early as possible and establishes, the attended operation with cell is further completed as early as possible, to recover business number
According to transmission.
Embodiment two
The present embodiment provides a kind of method of cell reselection based on above-described embodiment, mainly to the step in above-described embodiment
101 are described in further detail.
The mode of the cell information generation re-selecting cell information of the basis can be any one of following manner：
Mode one：The re-selecting cell information is generated according to the system message of the terminal storage.
System message can be including the information of current area at place and/or the adjacent area of current area before terminal re-selecting cell
System message.Terminal can generate re-selecting cell information according to the system message itself stored, such as terminal will receive
Neighboring BS information in system message is as re-selecting cell information.Specifically, system message can be included in recently received
Cell reselection thresholding and parameter in SIB3 and SIB4 in system message and/or the cell weight included in SIB11 and SIB12
List and parameter are selected, which offers a saving the time for reading new system message, so as to reduce the time of cell reselection.It is preferred that
Ground, system message are the recent systems message that terminal receives.
Mode two：The Neighboring Cell List issued according to network generates the re-selecting cell information, and the Neighboring Cell List is basis
What the terminal reported is measurement report generation or according to the neighboring BS information generation obtained in advance.
Terminal is per at regular intervals just to network reporting measurement reports.Network side generates according to the measurement report received
Neighboring Cell List, the Neighboring Cell List are a kind of special Neighboring Cell List.The Neighboring Cell List includes and institute before terminal re-selecting cell
In the information of adjacent each cell of cell.The cell number included in the Neighboring Cell List is typically less, such as including terminal
The best top n cell of radio signal quality in the measurement report of transmission, N here is the integer more than 1, such as can be
3rd, 5 or 10, configured with specific reference to being actually needed.So, due to reducing the scope of cell reselection, terminal can search as early as possible
Rope is to cell and initiates the connection with the cell of gravity treatment, completes cell reselection operation as early as possible.
