As shown in Figure 1, in the LTE system, air interface protocols is divided into Non-Access Stratum (Non AccessStratum, abbreviate NAS as) and Access Layer (Access Stratum, abbreviate AS as) two parts, wherein, Access Layer mainly comprises: radio resource control layer (Radio Resource Control, abbreviate RRC as), packet data convergence protocol (Packet Data Convergence Protocol, abbreviate PDCP as), wireless chain control layer (Radio Link Control, abbreviate RLC as), media access control layer (MediaAccess Control abbreviates MAC as) and physical layer (PHY).
Particularly, NAS mainly is responsible for subscriber equipment (User Equipment, abbreviate UE as) and core net (Core Network, abbreviate CN as) in Mobility Management Entity (Mobility ManagementEntity, abbreviate MME as) carry out the mutual of signaling, be used to carry out the renewal of registration, authentication, encryption, tracking area, the foundation of data service etc.; AS mainly is responsible for global grounding wireless access network (the Evolution Universal Terrestrial Radio Access Network with evolution, abbreviate E-UTRAN as) in evolved Node B (eNodeB) between communicate, be used to realize the carrying of Radio Resource control, NAS data and signaling etc.
Radio Resource control module among the AS (Radio Resources Control abbreviates RRC as) mainly is responsible for measurement, cell selecting and gravity treatment of the broadcasting of system message and reception, paging, RRC establishment of connection, maintenance and release, adjacent cell or the like.And according to the residing state of subscriber equipment, the Radio Resource control module is divided into RRC Idle state (RRC_IDLE) and RRC connected state (RRC_CONNECTED).
When the RRM module is in Idle state, UE and network side do not have the mutual of upstream data and dedicated signaling, and the contiguous frequency point information of the adjacent cell information that disposes in the system message of RRM module according to network side broadcasting, contiguous frequency point information or other standards is carried out the sub-district gravity treatment.Under this Idle state, if NAS need carry out professional foundation or because the sub-district gravity treatment causes the variation of tracking area, can trigger NAS and register at new tracking area.NAS will notify the RRM module to carry out the RRC establishment of connection and then carry out signaling establishment of connection (for RRC connects, connecting for signaling between eNodeB and the CN between UE and the eNodeB as shown in Figure 1).
Fig. 2 is the schematic diagram of the general frame example of the medium-term and long-term evolution system of correlation technique.As shown in Figure 2, wherein mainly comprise core net (CN), Evolved UTRAN (Evolved UniversalTerrestrial Radio Access Network abbreviates E-UTRAN as) and subscriber equipment three parts.
Interface among MME/ gateway in the core net (Serving Gateway abbreviates S-GW as) and the E-UTRAN between the eNB is the S1 interface, and the interface between subscriber equipment and the eNB is an X2 interface, and the interface between subscriber equipment and the subscriber equipment is the Uu interface.
Fig. 3 sets up the signaling process figure that RRC is connected between subscriber equipment and the Access Network in the correlation technique.As shown in Figure 3, mainly may further comprise the steps: the RRM module of user equipment side goes up in Common Control Channel (Common Control Channel abbreviates CCCH as) according to agreement and sends RRC connection request (RrcConnectionRequest).Access Network is replied RRC connection foundation (RrcConnectionSetup) after receiving the RRC connection request, in this message, distribute special-purpose Radio Resource to give subscriber equipment, after subscriber equipment finishes according to the parameter configuration of the private resource that distributes, at Dedicated Control Channel (Dedicated ControlChannel, abbreviate DCCH as) go up to send RRC and connect to set up and finish (RrcConnectionSetupComplete) message and give network side, and the signaling of in this message, carrying NAS.At this moment, RRC between subscriber equipment and the eNodeB connects to set up and finishes, and eNodeB then and set up signaling between the core net and connect and connects RRC and sets up the NAS signaling of carrying in the message that finishes and send to core net.
If terminal is in Idle state, physical layer can ceaselessly be measured adjacent cell, like this, connect in the process of setting up at RRC, if physical layer is ceaselessly measured adjacent cell, at any time may the triggering cell gravity treatment, if the sub-district gravity treatment occurs in after the transmission of RRC connection request, subscriber equipment can't be received that RRC that network side replys connects and set up message on the Common Control Channel of former sub-district, therefore can cause RRC to connect and set up failure, thereby influence the business foundation of NAS and the transmission of various signalings.
At in the correlation technique since the sub-district gravity treatment cause subscriber equipment can't set up that RRC connects and then reduce RRC connect and be created as power, influence that NAS is professional to be set up and signaling reception even can make the problem of the lost terminal network coverage, effective solution is not proposed at present as yet.

Embodiment
Can't set up the RRC connection (wherein at the subscriber equipment that causes owing to the sub-district gravity treatment in the correlation technique, the link setup that process all refers to not be subjected to system message obstruction in the sub-district is set up in RRC connection mentioned in this article) and then reduce the problem that the RRC connection is created as power, influences professional foundation of NAS and signaling reception, the present invention proposes, set up at needs under the situation of RRC connection, stop the processing relevant with the sub-district gravity treatment, thereby guaranteeing as far as possible that RRC connects can successfully set up, effectively improve RRC and connect the success rate of setting up, thereby effectively optimize the foundation of NAS business.
Describe embodiments of the invention in detail below in conjunction with accompanying drawing.
Fig. 4 is according to the flow chart of the preprocess method of the Radio Resource control connection foundation of the embodiment of the invention, as shown in Figure 4, may further comprise the steps:
Step S401 judges whether terminal carries out the Radio Resource control connection;
Step S403 enters the Radio Resource control connection when setting up in definite terminal, and terminal is forbidden the cell reselection process of terminal.
By means of above-mentioned processing, when setting up, the Radio Resource control connection in time forbids cell reselection process by entering in terminal, guarantee that the RRC that terminal can normally receive from Serving cell connects the relevant information of setting up, effectively improve RRC and connected foundation and the professional success rate of setting up of NAS, improved the response speed of user terminal, avoided terminal in the correlation technique can't normally receive the problem of message from Serving cell.
Wherein, after definite terminal entered the foundation of Radio Resource control connection, terminal can be proceeded adjacent cell measurement and handle.Preferably, in order to reduce the energy consumption of terminal, enter the Radio Resource control connection when setting up in definite terminal, further the adjacent cell measurement of terminating terminal is handled, and below detailed description is forbidden the mode of cell reselection process.
In above-mentioned processing, adjacent cell measurement is handled and is meant: according to the measurement of the adjacent cell information and executing adjacent cell in the network side system message, carry out measurements of neighboring cells result's assessment; Cell reselection process is meant: according to the assessment result of adjacent cell measurement processing, determine the Target cell of gravity treatment, reading and the suitable whether resident judgement in sub-district of the system message of execution Target cell, determine whether to carry out the sub-district gravity treatment, preferably, when stopping cell reselection process, the measurement and the system message that should stop adjacent sub-district read, thereby make terminal stop the measurement evaluation process of adjacent sub-district.
Particularly, under the Access Layer of the Non-Access Stratum of terminal notice terminal need carry out situation that the Radio Resource control connection sets up, determine that terminal enters the Radio Resource control connection and sets up.
In addition, because when terminal is in Idle state, terminal can constantly be carried out adjacent cell measurement, and adjacent cell measurement may trigger next step cell reselection process, therefore, enter the Radio Resource control connection when setting up in definite terminal, terminal may begin to carry out cell reselection process, also may not begin to carry out cell reselection process.Therefore, in step S403, if cell reselection process has begun to carry out, then terminal forbids that cell reselection process can be meant that the cell reselection process that will begin stops, for example, terminal can forbid itself reading the system message of adjacent sub-district, in order to reduce the energy consumption of terminal, preferably, can also further stop adjacent cell measurement handles; If cell reselection process does not begin to carry out as yet, then terminal forbids that cell reselection process can be meant that terminal stops himself execution cell reselection process, for example, on the one hand, terminal can be with this functional shielding of cell reselection process, like this, even the result that adjacent cell measurement is handled can the triggering cell re-selection process, terminal can not carried out the sub-district gravity treatment yet, on the other hand, terminal can also be directly handled adjacent cell measurement and is stopped, and the triggering of not only having avoided cell reselection process (promptly, reached the purpose of forbidding the sub-district gravity treatment), reduced the energy consumption of terminal simultaneously.
For example, preferably, can normally set up, reduce the energy consumption of terminal simultaneously in order to guarantee that RRC connects, terminal enter the Radio Resource control connection when setting up terminal begun to carry out under the situation of cell reselection process, terminal can stop adjacent cell measurement and handle and forbid cell reselection process; And enter the Radio Resource control connection when setting up in terminal, and terminal does not begin to carry out under the situation of cell reselection process, and terminal can only stop adjacent cell measurement and handle, thereby forbids that adjacent cell measurement handles the triggering cell re-selection process.
In addition, after definite terminal enters the foundation of Radio Resource control connection, terminal sends wireless resource control connection request message to its Serving cell, because cell reselection process stops, so terminal can normally receive from the Radio Resource control connection of its Serving cell and sets up message or the Radio Resource control connection is set up various information such as refuse information.
If receive from the Radio Resource control connection of Serving cell in the T300 timer official hour section of terminal after sending wireless resource control connection request and set up message, then terminal and Serving cell are set up the Radio Resource control connection.
On the other hand, set up failure if terminal is determined the Radio Resource control connection, then terminal can be removed the forbidding of described cell reselection process, if stopped the adjacent cell measurement processing before the terminal, then needed to restart adjacent cell measurement and handled.
Particularly, T300 timer after terminal sends wireless resource control connection request message is not set up message or terminal and is received and set up refuse information or terminal from the Radio Resource control connection of Serving cell and determine that the signal strength signal intensity of Serving cell does not satisfy under the situation of quality of service requirement (promptly receiving in the time period of pushing up from the Radio Resource control connection of Serving cell, terminal determines that this Serving cell is not suitable for continuing as this terminal service is provided), terminal is determined Radio Resource control connection foundation failure.
Usually, under the situation that the message that signal strength signal intensity at Serving cell is lower, the signal strength signal intensity of Serving cell decline very fast and/or Serving cell sends can't be received by terminal, terminal can determine that this Serving cell can not meet the demands, at this moment, terminal can continue to start adjacent cell measurement, so that gravity treatment is to the better adjacent sub-district of signal strength signal intensity.
By means of above-mentioned processing, when setting up, the Radio Resource control connection in time stops the processing relevant by entering with the sub-district gravity treatment in terminal, guarantee that the RRC that terminal can normally receive from Serving cell connects the relevant information of setting up, effectively improve RRC and connected foundation and the professional success rate of setting up of NAS, improved the response speed of user terminal, avoided terminal in the correlation technique can't normally receive the problem of message from Serving cell, and can occur in time the sub-district reselection functionality being recovered under the unusual situation at Serving cell, avoid the situation of the lost terminal network coverage to occur.
The present invention also provides a kind of pretreatment unit of Radio Resource control connection foundation and the terminal that comprises this device.
Fig. 5 is that as shown in Figure 5, this device can comprise according to the structured flowchart of the pretreatment unit of the Radio Resource control connection foundation of the embodiment of the invention:
Wherein, after definite terminal entered the foundation of Radio Resource control connection, terminal can be proceeded adjacent cell measurement and handle.Preferably, in order to reduce the energy consumption of terminal, enter the Radio Resource control connection when setting up in definite terminal, further the adjacent cell measurement of terminating terminal is handled, and below detailed description is forbidden the concrete executive mode of cell reselection process.
Particularly, adjacent cell measurement is handled and is meant: according to the measurement of the adjacent cell information and executing adjacent cell in the network side system message, carry out measurements of neighboring cells result's assessment; Cell reselection process is meant: according to the assessment result of adjacent cell measurement processing, determine whether to carry out the Target cell of sub-district gravity treatment and definite gravity treatment, reading and the suitable whether resident judgement in sub-district of executive system message, preferably, when pretreatment module stops cell reselection process, should stop reading the system message of gravity treatment Target cell, thereby the reselection evaluation that makes terminal stop the gravity treatment Target cell is handled.
Particularly, under the Access Layer of the Non-Access Stratum of terminal notice terminal need carry out situation that the Radio Resource control connection sets up, judge module determined that terminal enters the Radio Resource control connection and sets up.
In addition, because when terminal is in Idle state, terminal can constantly be carried out adjacent cell measurement, because adjacent cell measurement can trigger next step cell reselection process, therefore, enter the Radio Resource control connection when setting up in definite terminal, terminal may begin to carry out cell reselection process, also may not begin to carry out cell reselection process.Therefore, if judge that cell reselection process had begun to carry out when terminal was carried out the Radio Resource control connection, then pretreatment module forbids that cell reselection process is meant that the cell reselection process that will begin stops, for example, terminal can forbid itself reading the system message of adjacent sub-district, in order to reduce the energy consumption of terminal, preferably, can also further stop adjacent cell measurement and handle; If cell reselection process does not begin to carry out as yet, then terminal forbids that cell reselection process is meant that terminal stops himself execution cell reselection process, for example, on the one hand, pretreatment module can be with this functional shielding of cell reselection process, like this, even the result that adjacent cell measurement is handled can the triggering cell re-selection process, terminal can not carried out the sub-district gravity treatment yet, on the other hand, pretreatment module can be directly handled adjacent cell measurement and is stopped, and the triggering of not only having avoided cell reselection process (promptly, reached the purpose of forbidding the sub-district gravity treatment), reduced energy consumption simultaneously.
For example, preferably, can normally set up in order to guarantee that RRC connects, reduce the energy consumption of terminal simultaneously, terminal enter the Radio Resource control connection when setting up terminal begun to carry out under the situation of cell reselection process, pretreatment module can stop adjacent cell measurement and handle and forbid cell reselection process; And enter the Radio Resource control connection when setting up in terminal, and terminal does not begin to carry out under the situation of cell reselection process, and pretreatment module can only stop adjacent cell measurement and handle, thereby forbids that adjacent cell measurement handles the triggering cell re-selection process.
Usually, can comprise in the terminal: measuring management module (not shown), be used for measurement according to the adjacent cell information and executing adjacent cell in the network side system message, carry out measurements of neighboring cells result's assessment, and according to assessment result notifying cell selection/reselection module execution sub-district gravity treatment, that is, carrying out adjacent cell measurement handles.
Cell selecting/gravity treatment module (not shown) is used for reading and the judgement that whether suitable the sub-district is of executive system message, and will select or the cell information report of gravity treatment success is given judge module and measuring management module,, carries out cell reselection process that is.
Because the cell measurement that the measuring management module can stop himself carrying out is handled, and cell selecting/gravity treatment module can stop the cell reselection process that himself is carried out, therefore, after said apparatus being arranged in the middle of the terminal, can think that measuring management module and cell selecting/gravity treatment module has comprised the function of above-mentioned pretreatment module.
For example, if cell selecting/gravity treatment module is being in the process of cell reselection process, then cell selecting/gravity treatment module stops current cell reselection process, notifies the measuring management module to stop measurements of neighboring cells except that the service sub-district then; On the other hand, if cell selecting/gravity treatment module is not carried out cell reselection process, then the measuring management module need stop the measurement to the adjacent cell except that the service sub-district.
In addition, also can comprise the connection management module in the terminal, after said apparatus is arranged at terminal, can think that the connection management module has the function of above-mentioned judge module, and the connection management module also is used to receive the RRC connection request of Non-Access Stratum, and will set up the result notification Non-Access Stratum after link setup success or failure.
In addition, after definite terminal enters the foundation of Radio Resource control connection, terminal sends wireless resource control connection request message to its Serving cell, because cell reselection process stops, so terminal can normally receive from the Radio Resource control connection of its Serving cell and sets up message or the Radio Resource control connection is set up refuse information.
Afterwards, the connection management module can send RRC connection request message to network side on the Common Control Channel of current Serving cell, and process protection timer T300 is set up in startup RRC connection.Follow-up processing procedure will comprise following several situation:
