The present invention specifically can be applied to user terminal and carry out in the scene of channel type conversion, also can be applied to user terminal carries out in the scene of sub-district reselection operation, perhaps, the user terminal that can be applied to leave service area reenters in the application scenarios of service area, perhaps, can also be applied to user terminal when Routing Area/registration area changes, in the application scenarios that execution LA/RA update (routing region updating or registration area upgrade) operates in the new sub-district of selecting (only limiting to the former scene that causes LA/RA to change because of the sub-district gravity treatment of described LA/RA update), or the like.Below in conjunction with accompanying drawing the specific implementation process that the present invention is applied in the different scenes is described.
(1) the present invention can be applied to user terminal in the processing procedure of execution channel type conversion, is carrying out the channel type conversion, i.e. time delay in the state transition process, the performance of raising communication system to reduce user terminal.
Be and reduce described time delay, the technological means that the present invention mainly adopts is: will need the information content that issues by system broadcast message in the channel type transfer process, give user terminal by point-to-point transmitting signaling downwards, wait for the time that receives the corresponding information content to reduce user terminal, for example, can send to user terminal with in the channel switch process, needing to be encapsulated in the point-to-point message by the measurement configuration information that system broadcast message issues.
That is to say, the present invention need wait for the information content that the long period just can obtain from the system broadcasts control channel with user terminal, be handed down to user terminal by point-to-point message by network side, obtain the needed time of the corresponding information content thereby reduce user terminal.
The present invention is in implementation procedure, be specifically as follows: receiving the reconfigure command of network side transmitted at user terminal after, in the time of need entering into common signal channel (as Cell_FACH) state, user terminal can be carried out sub-district gravity treatment or cell selecting process to select a suitable resident sub-district.If the result of cell selecting/sub-district gravity treatment is not the resident sub-district of active user's terminal, perhaps, the result of cell selecting is not the sub-district or the frequency of appointment in the physical layer reconfiguration message, the network side of bigger system broadcast message such as SIB11/SIB12 information need obtain from to(for) those user terminals so, specifically be handed down to user terminal by point-to-point message by network side, like this, just, can effectively reduce user terminal and obtain the time delay that needs in the process of described SIB11/SIB12 information.
Simultaneously, the present invention can also be used for giving user terminal with described system broadcast message by point-to-point transmitting signaling downwards in other application scenarioss except that state transition is handled.
In addition, the present invention is in the specific implementation process, can select all system broadcast message are handed down to user terminal by point-to-point message, also can only select the information content in the system broadcast message that part needs to be handed down to user terminal by point-to-point message.
For ease of the understanding of the present invention, the specific implementation that the present invention is applied under the channel type shift scene is elaborated below in conjunction with accompanying drawing.
Embodiment one
In this embodiment, network side issues the content of described SIB11/SIB12 by point-to-point message, thereby the time delay that the SIB11/SIB12 on the broadcast channels to be read such as minimizing user terminal brings, and described point-to-point message is to be handed down to user terminal by dedicated channel, the specific implementation process of this embodiment specifically comprises following treatment step as shown in Figure 3:
Step 21: network side, promptly UTRAN (Radio Access Network) sends to user terminal and reshuffles signaling, and described signaling is used for indicating terminal and needs to enter the CELL_FACH state after carrying out reconfigure command;
Step 22: after terminal is received described RRC signaling message, carry out pre-cell selecting operation, the sub-district of determining to satisfy the cell selecting criterion;
Owing in user terminal, can preserve an adjacent area list information synchronous with network side, make user terminal can from described Neighboring Cell List, obtain the neighboring BS information of current area, comprise ID (sign) information of adjacent area, the main scrambling code information of adjacent area etc.; Therefore, the concrete processing of this step can for: according to the adjacent area list information of storing in the user terminal, in the adjacent area, carry out pre-cell selecting, described pre-cell selecting is meant to be measured signal quality of adjacent cells, and definite sub-district ID that satisfies the cell selecting criterion accordingly, so that report network side by RRC signaling (as cell update signaling etc.), as network equipments such as RNC or node B;
In addition, in this step, user terminal also is transformed into the configuration information that needs under the FACH state with the storage networking side by what the transmission of RRC signaling message came, it is new configuration information, but, user terminal is not temporarily used these configurations, promptly temporarily be not transformed under the FACH state, but still use current configuration, promptly under original sub-district and state, continue to receive and send data, when the time of activating new configuration information arrives, use described new configuration again, in the process that arrives in the time of waiting new configuration information to be activated, the operation of system broadcast message that promptly can carry out described pre-cell selecting operation and obtain pre-cell selecting result's sub-district;
Step 23: user terminal uses Dedicated Control Channel to send message to network in current area, gives network side with the reporting district information of determining that satisfies the cell selecting criterion;
Promptly by the result notification RNC of RRC dedicated signaling with pre-cell selecting, for example, can be by the result notification network side with pre-cell selecting such as cell update signaling, the result of described pre-cell selecting comprises the ID of Target cell, and the result who reports can be the cell id (sub-district ID) of a plurality of S of satisfying criterions;
As a result the time, reporting a sub-district to the above-mentioned pre-cell selecting of network side, also can report a plurality of sub-districts, if report a plurality of sub-districts, then can report after the signal quality ordering according to a plurality of sub-districts, so that the selection operation of network side;
User terminal can also inform in the lump whether network side needs to issue SIB11/SIB12 by point-to-point message in this step, for example, be used to indicate network side whether to need to issue SIB11/SIB12 by an indication information flag bit that in RRC message, is provided with by RRC message, can be set to: when this flag bit is 1, expression need issue SIB11/SIB12 by RRC message, when this flag bit was 0, then expression did not need to issue SIB11/SIB12 by RRC message; Certainly, in this RRC message, also corresponding indication information can be set, as long as and be unified in network side and be set to receive that just this message carries out the operation that issues SIB11/SIB12 by RRC message;
Terminal also can be informed the tabulation of the system broadcast message type that network need issue by point-to-point message by RRC message in this step, for example, and SIBx, SIBy, SIBz or the like.
Specifically as shown in the figure, user terminal can use DCCH (Dedicated Control Channel) to send System information Request (system information request) message to network side, with the indication of the result and the request SIB11/SIB12 information of the described pre-cell selecting of informing network side.
Step 24: the Target Cell Identifier that network is then determined according to pre-cell selecting result is encapsulated in the SIB11/SIB12 of corresponding described Target cell in the point-to-point RRC message and is handed down to user terminal;
Be specifically as follows: RNC according to described pre-cell selecting as a result the SIB information of each sub-district of correspondence judge whether each sub-district is Suitable cell (suitable sub-district), promptly need PLMN (public land mobile net) information that Target cell is belonged to, and whether the state of this sub-district is that barred (forbidding) information is judged, can also judge in conjunction with RRM (intelligent radio resource management) algorithm, and the SIB11/SIB12 of suitable resident Target cell is carried in the point-to-point RRC message is handed down to user terminal, perhaps, the SIB11/SIB12 that also can carry a plurality of Target cells selects for it for user terminal;
Specifically can send the SIB11/SIB12 information of Target cell by Complete System Information (complete system information) message to the user terminal carrying;
Step 25: after user terminal is received described point-to-point RRC message, the SIB11/SIB12 that comprises in the storing message, and carry out state transition and handle, enter into common channel state, i.e. the Cell_FACH state;
Be specially: user terminal is preserved the configuration information in the reconfigure command, and when arriving, uses the activationary time of new configuration information new configuration information again, migration enters the Cell_FACH state, simultaneously, after having determined suitable resident sub-district, read the MIB of selected definite Target cell from system broadcast message, SIB1, SIB3/4, SIB5/6 and SIB7 information read SIB11/12 but postpone;
In addition, if user terminal has obtained the MIB of Target cell from the point-to-point RRC message of receiving, SIB1, SIB3/4, SIB5/6 and SIB7, then user terminal also need not to read the corresponding information content again from system broadcast message in this step, and promptly user terminal only need read its NO corresponding information from system broadcast message in this step.
Step 26: carry out the cell update processing procedure and finish response signaling with reshuffling;
Be user terminal is initiated cell updating course/reconfigure command in the new sub-district of selecting response message, i.e. channel type conversion and cell selecting operation have been finished in expression.
Embodiment two
In this embodiment, specifically be that the SIB11/SIB12 message that user terminal need obtain is encapsulated in the RRC signaling message, and be handed down to user terminal by Common Control Channel (CCCH);
The specific implementation process of this embodiment specifically may further comprise the steps as shown in Figure 4:
Step 31: network side, promptly UTRAN sends reconfigure command to user terminal, and indicating terminal need enter common signal channel (being the CELL_FACH state);
In described RRC signaling message, also comprise user terminal enter common signal channel after employed new configuration information;
Step 32: after user terminal receives described reconfigure command, carry out reconfiguration operation, and enter the CELL_FACH state, and carry out the cell selecting operation according to the RRC state information in the reconfigure command (being the indication information that terminal need enter common signal channel);
Step 33: after user terminal was carried out the cell selecting operation, the initial necessary minimum system broadcast message that inserts was initiated in the sub-district that reads in new selection, comprises MIB, SIB1, SIB3/4, SIB5/6 and SIB7, but did not comprise and read SIB11/SIB12;
Step 34: user terminal is to the Indication message of network side transmission acquisition request SIB11/SIB12 information, and the corresponding request message of network side basis is handed down to user terminal with the SIB11/SIB12 information of user terminal requests;
That is to say, user terminal can also inform whether network side needs to issue SIB11/SIB12 by point-to-point message in this step, for example, be used to indicate network side whether to need to issue SIB11/SIB12 by an indication information flag bit that in point-to-point message, is provided with by RRC message, can be set to: when this flag bit is 1, expression need issue SIB11/SIB12 by point-to-point message, when this flag bit was 0, then expression did not need to issue SIB11/SIB12 by point-to-point message; Certainly, in this cell update message, also corresponding indication information can be set, as long as and be unified in network side and be set to receive that just this cell update message carries out the operation that issues SIB11/SIB12 by point-to-point message;
Perhaps, in this step, can also on the basis of the content of SIB11/SIB12, comprise more system broadcast message information;
Specifically as shown in Figure 4, user terminal can use CCCH, and Common Control Channel sends System information Request message to network side, and the request network side issues the SIB11/SIB12 information that user terminal needs; And, can use the CCCH Common Control Channel to send point-to-point SIB11/SIB12 information at network side by the encapsulation of Complete System Information message and to user terminal;
Step 35: user terminal is initiated cell updating course in the new sub-district of selecting;
Need to prove that the processing that above-mentioned steps 34 is carried out also can be finished in the lump, finishes simultaneously if be chosen in the cell updating course in cell updating course, then can omit and carry out described step 34;
If be chosen in completing steps 34 described processing in the lump in the cell updating course, then need indicate in cell update message (being RRC message) needs network to issue SIB11/SIB12; And by network side the content of the SIB11/SIB12 of new sub-district is encapsulated in the cell update acknowledge message and is handed down to user terminal;
In addition, if step 34 and step 35 are to finish by two independent signalings, can there be sequential relationship between these two signalings so.
Step 36: after user terminal obtains corresponding system broadcast message, just can in new sub-district, send reconfigure command and finish response message;
So far, finish the channel type conversion and the cell selecting operation of user terminal.
Embodiment three
This embodiment applied scene is: user terminal was in the Cell_Fach state originally, and indicating terminal still is in the Cell_Fach state in the reconfigure command after execution is reshuffled; User terminal need be initiated cell updating course (being mapped on the CCCH by RACH) and reshuffle signaling response signaling (being mapped to DCCH by RACH) in the new sub-district of selecting;
Among this embodiment, among concrete processing procedure and the embodiment two, be that processing procedure shown in Figure 4 is similar, specifically as shown in Figure 5, only be that this embodiment is different with embodiment two applied scene, state transition has taken place in terminal among the embodiment two in the process of reshuffling, from Cell_DCH state transition to the Cell_FACH state, and among the embodiment three, terminal was in the Cell_FACH state before reconfiguration course, still be in the Cell_FACH state after reshuffling, so no longer describe concrete realization processing procedure in detail at this.
In addition, need to prove, in embodiment two and embodiment three, System information Request (system information request) signaling that sends on the CCCH channel and be used for the CompleteSIB11/SIB12 signaling, it can be an independent point-to-point RRC signaling, also can be as the part in Cell update (cell update) message, with the part of Complete SIB11/SIB12 (complete SIB11/SIB12) signaling content with Systeminformation Request information as Cell updateconfirm (cell update affirmation) message;
And, in the above embodiments one to the above embodiments three, be example just with SIB11/SIB12, in actual applications, can in system information request request and Completesystem information signaling, can carry more eurypalynous system broadcast message information; Promptly the system broadcast message information that sends to user terminal by point-to-point message is not limited in the SIB11/SIB12 information as measurement configuration information.
To the above embodiments three, described reconfigure command includes but not limited to any one signaling of enumerating for following at the foregoing description one:
