Description
Technical field
The present invention relates to mobile communication technology, particularly a kind of neighboring cell list configuration method and system and a kind of terminal.
Background technology
Current, introduced multi-carrier frequency cell in Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, the Time Division-Synchronous Code Division Multiple Access) system, be used to improve number of users and the user rate that the sub-district is supported.Carrier frequency in the multi-carrier frequency cell is divided into main carrier frequency and assistant carrier frequency two classes, wherein, main carrier frequency is meant and has carried downlink pilot frequency channel (DwPCH, Downlink Pilot Channel) and Primary Common Control Physical Channel (P-CCPCH, Primary Common Control Physical Channel) carrier frequency, correspondingly, assistant carrier frequency then is meant the carrier frequency that does not carry DwPCH and P-CCPCH.Single carrier cell can be thought a kind of special shape of multi-carrier frequency cell.
For each sub-district, the corresponding adjacent cell list in capital, comprise in this adjacent cell list: co-frequency neighbor cell list, iso-frequency adjacent community tabulation and different system adjacent cell list, or be called different radio access technologies (RAT, Radio Access Technology) cell list is promptly with the different sub-district of wireless access technology of sub-district, terminal place.Because different system adjacent cell list and scheme of the present invention are irrelevant, so be not described.Co-frequency neighbor cell list and iso-frequency adjacent community tabulation are the basic foundations that terminal is carried out common frequency measurement and different-frequency measure and sub-district gravity treatment.
For the adjacent sub-district of single carrier frequency,, then think to be positioned over the co-frequency neighbor cell that this neighbour sub-district is sub-district, terminal place in the co-frequency neighbor cell list of adjacent cell list if the carrier frequency of adjacent sub-district is identical with the carrier frequency of sub-district, the current place of terminal; Otherwise be iso-frequency adjacent community, be positioned in the iso-frequency adjacent community tabulation of adjacent cell list.For multi-carrier frequency cell, co-frequency neighbor cell and iso-frequency adjacent community reference be the main carrier frequency of sub-district, terminal place, the main carrier frequency of even adjacent sub-district is identical with the main carrier frequency of sub-district, terminal place, then think and be positioned over the co-frequency neighbor cell that this neighbour sub-district is sub-district, terminal place in the co-frequency neighbor cell list of adjacent cell list; Otherwise be iso-frequency adjacent community, be positioned in the iso-frequency adjacent community tabulation of adjacent cell list.
Adjacent cell list is configured by operator at the sub-district establishment stage, does not generally change, and can be notified to terminal by system broadcast message or dedicated signaling by radio network controller (RNC, radio network control).
System broadcast message is made up of multiple systems block of information (SIB, System Information Block), and that wherein relevant with scheme of the present invention is SIB 11 and SIB 12.SIB11 is used to be in the terminal of idle condition, and SIB 12 is used to be in the terminal of connection status.But if there is not SIB12 in the system broadcast message, the terminal that is in connection status so also can be used SIB11.
Terminal in the multi-carrier frequency cell can be operated in main carrier frequency or assistant carrier frequency, system broadcast message only sends on the main carrier frequency of sub-district, that is to say that for the terminal that is operated in main carrier frequency, the adjacent cell list that carries in the system broadcast message is exactly the current adjacent cell list of terminal; But for the terminal that is operated in assistant carrier frequency, because variation has taken place in working carrier frequency, so adjacent cell list that the required adjacent cell list of terminal just carries in the frame of reference broadcast again, but need by dedicated signaling, obtain corresponding adjacent cell list as measuring control messages (MEASUREMENT CONTROL).Specifically, for the terminal that is in the different operating state, its corresponding adjacent cell list obtain manner is as follows respectively:
The terminal that is under the idle condition only is operated in main carrier frequency, obtains adjacent cell list by receiving system broadcast (SIB 11).
The terminal that is under the idle condition can enter connection status by initiating Radio Resource control (RRC, Radio Resource Control) the connection request of setting up, and comprises CELL_DCH state and CELL_FACH state.The mode of specifically setting up is: terminal sends RRC to RNC and connects the request of setting up (RRC CONNECTION REQUEST); After RNC receives this message, be the required Radio Resource of terminal distribution, and connect foundation (RRC CONNECTION SETUP) message, wherein carry connection status and working carrier frequency that terminal will enter to terminal loopback RRC; Terminal connects to set up to RNC feedback RRC finishes (RRC CONNECTION SETUP COMPLETE) message.
For being in the CELL_DCH state and being operated in the terminal of main carrier frequency, (SIB12/SIB11) obtains adjacent cell list by the receiving system broadcast; For being in the CELL_DCH state and being operated in the terminal of assistant carrier frequency, measure control messages and obtain adjacent cell list by receiving.
For being in the CELL_FACH state and working in the terminal of main carrier frequency, can obtain adjacent cell list by receiving system broadcast (SIB 12/SIB 11) equally.
But for being in the CELL_FACH state and working in the terminal of assistant carrier frequency, do not have in the existing protocol and how to handle after prescribed terminal receives the measurement control messages, that is to say that terminal can not be obtained and the corresponding adjacent cell list of assistant carrier frequency in this way.So, terminal can only the using system broadcast or other state in the adjacent cell list stored, and as can be known based on before introduction, adjacent cell list in the system broadcast message is provided with reference to main carrier frequency, and be not suitable for assistant carrier frequency, and obviously, the adjacent cell list of storing in other state also not necessarily is applicable to current state, can't carry out correct sub-district gravity treatment so will cause follow-up terminal, and, terminal can't report RNC with correct same frequency, different-frequency measure result, causes RNC can't carry out efficient radio resource management.

Embodiment
At problems of the prior art, propose a kind of brand-new adjacent cell list among the present invention and obtain scheme, that is: the terminal that is under the CELL_FACH state determines whether the working carrier frequency of self is assistant carrier frequency, if then extract the adjacent cell list in the appointment signaling receive and preserve.Wherein, the state of terminal is that RNC by network side is configured.
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
Fig. 1 is the flow chart of the inventive method embodiment.As shown in Figure 1, may further comprise the steps:
Step 101:RNC by dedicated signaling with terminal configuration under CELL_FACH state assistant carrier frequency.
Before this step, suppose terminal works under main carrier frequency, so according to before introduction as can be known, terminal can be by the system broadcast message (SIB11 or SIB12) that receives, and obtains place adjacent cells of cells tabulation and preserves.The adjacent cell list of being mentioned in the present embodiment comprises co-frequency neighbor cell list and iso-frequency adjacent community tabulation.
In a certain then moment, RNC need change the connection status and the working carrier frequency of terminal, sends dedicated signaling to terminal, and terminal configuration is arrived under the CELL_FACH state assistant carrier frequency.Described dedicated signaling can be: the Radio Resource control connection is set up (RRC CONNECTION SETUP), radio bearer and is set up (RADIO BEARER SETUP), radio bearer and reshuffle that (RADIO BEARER RECONFIGURATION), transmission channel are reshuffled (TRANSPORT CHANNEL RECONFIGURATION), physical channel is reshuffled (PHYSICAL CHANNEL RECONFIGURATION), or cell update is confirmed (CELL UPDATE CONFIRM) etc.Carry connection status and carrier frequency information such as (being working carrier frequency) that terminal will enter in this dedicated signaling.Specifically how to be configured to known in this fieldly, to repeat no more.
Step 102: terminal determines whether the working carrier frequency of self is assistant carrier frequency, if then execution in step 103; Otherwise, process ends.
In this step, terminal is extracted the carrier frequency information in the dedicated signaling that receives, and this carrier frequency that extracts and the known carrier frequency that carries DwPCH and P-CCPCH (being the main carrier frequency of sub-district, terminal place) compared, determine whether both are consistent, if think that then the working carrier frequency of terminal is a main carrier frequency; Otherwise, think that the working carrier frequency of terminal is an assistant carrier frequency.It is known in this field how obtaining the carrier frequency that carries DwPCH and P-CCPCH.
In addition,, illustrate that then the working carrier frequency of terminal still is main carrier frequency, need not to obtain again adjacent cell list, so direct process ends if judged result is a "No".
Step 103: terminal is extracted the adjacent cell list in the appointment signaling that is received from RNC and is preserved process ends.
Here the appointment signaling of being mentioned can be meant the reconfiguration message etc. after existing measurement control messages or the expansion.For measuring control messages, to introduce before, itself just carries adjacent cell list information; And reconfiguration message is being generally used in the prior art when business that terminal is carried out changes, and the notice terminal is its resource that reconfigures, and as time slot etc., in the present embodiment, this message can be expanded, to carry adjacent cell list.Certainly, adopt other message to carry adjacent cell list and also be fine, herein only for illustrating.
After terminal receives measurement control messages or reconfiguration message from RNC, extract the adjacent cell list that wherein carries, and the adjacent cell list that has existed before replacing it with the adjacent cell list that this extracts, promptly in the step 101 when the adjacent cell list of terminal works during in main carrier frequency; Perhaps, can not replace yet, but the adjacent cell list that extracts in the adjacent cell list that has existed before preserving simultaneously and this step.
The benefit of Chu Liing is like this: in the subsequent process, when terminal receives dedicated signaling from RNC once more, after self working carrier frequency changed to main carrier frequency by assistant carrier frequency, if replaced the adjacent cell list of main carrier frequency correspondence before with the adjacent cell list of assistant carrier frequency correspondence, terminal then needs reading system broadcast again so, and extracts and preserve the adjacent cell list of the main carrier frequency correspondence of wherein carrying; If but preserved adjacent cell list before simultaneously corresponding to main carrier frequency and assistant carrier frequency, so then can be directly with preserved corresponding to the adjacent cell list of main carrier frequency adjacent cell list as working carrier frequency terminal after changing, need not to obtain again again.
So, for terminal, after its working carrier frequency changes to main carrier frequency by assistant carrier frequency, what it will be done is exactly to judge whether self preserves the adjacent cell list corresponding with main carrier frequency, if have, then directly with the adjacent cell list preserved as the required adjacent cell list of working carrier frequency terminal after changing; Otherwise the adjacent cell list in the system broadcast message that extraction receives is also preserved.
In addition, if after execution of step 103, terminal is CELL_DCH state with self working state by the CELL_FACH Status Change according to the dedicated signaling that is received from RNC again, but working carrier frequency does not change, then in this case, terminal need not to obtain again adjacent cell list, but the adjacent cell list that can directly use in the step 103 to be preserved.
Need to prove, if the sub-district gravity treatment takes place in terminal under the CELL_FACH state, promptly cell change takes place after, can adopt mode shown in Figure 1 to obtain required adjacent cell list equally.
