Terminal typically has five states:Idle is (idle)State, CELL-DCH
(CELL-Dedicated Channel, 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 physical channel for transmitting data is assigned in terminal, except the special physical channel of up-downgoing( Dedicated Physical
Channel, DPCH) sunset is foretold, terminal is also possible to be allocated physically DSCH Downlink Shared Channel PUSCH (Physical Uplink Shared Channel) and/or PDSCH (Physical Downlink Shared Channel), just blunt according to UTRAN (Universal Mobile Telecommunications System
Terrestrial Radio Access Network, UMTS land radio access web)Distribution condition, terminal can use dedicated transmission channel, up shared transmission channel(Uplink Shared Channel, USCH), downlink shared transmission channel(High-Speed Downlink Shared Channel, DSCH), and these transmission channels combination.When terminal is 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, corresponding co-frequency cell configurating terminal is added activation and collected by network side.The essential characteristic of CELL-FACH states is, the DPCH connection for being used to transmit data is not present between terminal and UTRAN, terminal will continuously monitor FACH transmission channels in down direction, and can use public or shared transmission channel in up direction.The change of system information will be broadcast to terminal in time by UTRAN by corresponding schedule information on FACH, so that terminal re-reads corresponding system letter when the terminal in CS domains detects SRB2 generation RUE, just switch to non-CELL-DCH states from CELL-DCH states, terminal carries out re-selecting cell operation in non-CELL-DCH states, when the operation for carrying out re-selecting cell reaches that the operation of re-selecting cell, the real call drop of terminal has not been completed in certain time.
Specifically, when terminal retransmit PDU exceed certain amount when, send when window reaches maximized window or receive the sequence number for including mistake of recipient's transmission(Sequence Number) Status PDU (status protocol data units, Status Protocol Data Unit) when, terminal initiates RLC Reset processes, sending a Reset PDU to bottom, (Reset Protocol Data Unit reset protocol Data Unit), and start corresponding timer, if within the time as defined in timer, terminal have received to should be in Reset PDU Reset ACK (acknowledgement character confirm character)(Reset Sequence Number reset sequence number by PDU, i.e. both RSN)When identical, then timer stops, and otherwise resends Reset PDU.Because SRB2 most Reset numbers are 1, so if terminal initiates RLC Reset processes, and corresponding ACK PDU are not received by within the time as defined in timer, it is determined that detect SRB2 and occur RUE.
Terminal is detected after SRB2 generations RUE, and the operation of re-selecting cell can be carried out as early as possible.This is because, terminal can not carry out the transmission of the mass data similar to call in non-CELL-DCH states, it is therefore desirable to the reselection operation of cell is completed as early as possible, to return to CEI-DCH states from non-CELL-DCH states.
Specifically, the system message that terminal is issued according to network side( System Information Block,
SIB multiple systems message element can be had by) reselecting in cell, system message, specific as follows:
SB1、 SB2:SIB schedule information; SIB1 :NAS (Non Access Stratum, Non-Access Stratum)The system information and terminal timer/counter of layer; SIB2: URA(UTRAN

Embodiment one
The present embodiment provides a kind of method of re-selecting cell, for when terminal detects generation RUE, the gravity treatment of cell can be completed as early as possible.The present embodiment is applied to existing GSM, UMTS network, LTE (Long Term Evolution, Long Term Evolution project) 4G.The executive agent of the present embodiment is terminal.
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 occurring RUE, terminal starts cell reselection operation.The purpose of cell reselection is terminal is connected again with cell, and recovers the business in CS domains, i.e. terminal and need to rebuild SRB2 and reacquire dedicated channel, that is to say, that terminal is switched to CELL-DCH states again from non-CELL-DCH states.Here the cell of terminal gravity treatment may is that identical from cell when occurring RUE or different with cell when occurring RUE.
The re-selecting cell information includes terminal and initiates to be connected with cell:Cell ID, cell biasing, adjacent area scrambler and neighbor pilot etc., terminal can just reconnect to cell according to the re-selecting cell information, and how terminal is prior art according to re-selecting cell information re-selecting cell, be will not be repeated here.
I^E'J, area's information can be terminal need gravity treatment ' ", the gravity treatment d that includes in the system message that meets ^ ' j before area, area's information; or cell information or 4 adjacent area cell informations arrived that ^ ^ network side is issued are connect before terminal; that is should ' ", area's message be terminal need gravity treatment ' ", area when all cell informations in terminal inner of ^, i.e., cell information known to terminal.It is preferred to use newest ^ ^ re-selecting cell information in the present embodiment, can so ensures the availability of cell information as far as possible.The newest re-selecting cell information for meeting ^ ^, refer to terminal ^^ then to time nearest cell information when occurring RUE.The cell information is ^ all in the terminal.
Step 102, according to re-selecting cell information, initiate the connection with the cell of gravity treatment and set up.
Terminal initiates the connection with cell, i.e., switch to again from non-CELL-DCH states
CELL DCH states, to recover original business.
In the present embodiment, when terminal needs to choose cell foundation connection accordingly again, re-selecting cell information is generated according to the cell information obtained, so, terminal may dispense with the time for obtaining re-selecting cell information, so as to accelerate cell reselection process, the connection with cell is initiated as early as possible and is set up, the attended operation with cell is further completed as early as possible, to recover the transmission of business datum.
Embodiment two
The present embodiment provides a kind of method of cell reselection based on above-described embodiment, and mainly the step 101 in above-described embodiment is 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:According to the system message of the terminal storage generate the gravity treatment ' ", area's information.
System message can wrap ^^ winter end gravity treatments ' ", the system message of the adjacent area of the information of current area where before area and/or current area.Terminal can generate re-selecting cell information according to system message all itself ^, and such as terminal regard the neighboring BS information in the system message for meeting ^^ as re-selecting cell information.Cell reselection door in ground, SIB3 and SIB4 that system message can be included in the newest system message for meeting ^ ^ and/or is included in Jie ^
Cell reselection row ^^ t in Smil and SIB12, which offers a saving the time for reading new system message, so as to reduce the time of cell reselection.Preferably, system message is the recent systems message that terminal meets ^ ^.
Mode two:The adjacent area row i issued according to network is into the re-selecting cell information, and the adjacent area arranges that the measurement report reported according to the terminal is generated or being generated according to the neighboring BS information obtained in advance.
Terminal is per at regular intervals just to network reporting measurement reports.Network side generates Neighboring Cell List according to the measurement report received, and the Neighboring Cell List is a kind of special Neighboring Cell List.The Neighboring Cell List includes the information with each adjacent cell of place cell before terminal re-selecting cell.The cell number included in the Neighboring Cell List is typically less, such as best top n cell of radio signal quality in the measurement report sent including terminal, here N is the integer more than 1, for example, can be 3,5 or 10, be configured with specific reference to being actually needed.So, due to reducing the scope of cell reselection, terminal can search the connection of the cell of d, area and initiation and gravity treatment as early as possible, cell reselection operation is completed as early as possible.
Neighboring Cell List may also be according to the neighboring BS information generation obtained in advance.For example, network is when receiving the measurement report that other terminals are reported, the neighboring BS information that the corresponding terminal is currently located cell can be got;Either by the artificial advance information in all cells of network configuration, so, network can also get the neighboring BS information that the terminal is currently located cell.
