Description
Technical field
The present invention relates to user terminal, relate in particular to the method and apparatus that is used to promote cell reselection priority in the user terminal.
Background technology
After the user terminal start and residing in main plot (serving cell), this user terminal is in idle condition (idle), and it periodically intercepts paging message, and detects the main plot.Consider the variation of received signal quality; The free subscriber terminal maybe be regular according to cell reselection priority and cell reselection priority, for example, and S criterion (S criterion) and R criterion (R criterion); Carry out district reselecting, to reside on the preferred sub-district.Cell reselection priority is a primary factor that influences the district reselecting result.
At present, cell reselection priority is to be configured by operator, and for example, operator has considered factors such as load balancing, formulates corresponding gravity treatment priority policy.And user terminal possibly receive multiple business, comprises unicast service, and multimedia broadcasting and/or multicast service (Multimedia Broadcast/Multicast Service, MBMS Service).Therefore; Iff provides condition information according to the MBMS business; The height of setting cell reselection priority is irrational; Because the cell reselection priority by operator's configuration possibly influence all user terminals, not only comprise the user terminal of supporting that MBMS is professional, also comprise the user terminal of not supporting that MBMS is professional.
In order to keep the professional continuity of MBMS substantially, the free subscriber terminal preferably will have the professional neighbor cell of its MBMS interested or that receiving as the target re-selecting cell.Therefore; RAN 2#74 meeting for the successional conclusion of free subscriber terminal traffic is; The free subscriber terminal is when receiving the MBMS business, and the gravity treatment priority that automatically will receive the professional frequency of MBMS promotes and is the highest gravity treatment priority, and uses the gravity treatment rule of routine.
In existing scheme, (Electronic Service Guide provides MBMS professional zero-time in ESG) at the electron service instruction of application layer.In addition, the frequency of the carrier frequency of broadcasting MBMS business also can or adopt other application layer methods to provide on ESG.After user terminal received ESG, user terminal according to the MBMS service related information that this ESG or other application layers provide, was reselected suitable frequency and neighbor cell before receiving the MBMS business.
Summary of the invention
Existingly provide the professional zero-time of MBMS to have following problem through ESG:
1) the MBMS business should be transmitted on the frequency indicated by ESG.ESG normally consider application layer message and carry out formative, and for whole public land mobile net (Public Land Mobile Network, PLMN) or all effective in the bigger geographic area.Therefore, be difficult to guarantee that the ESG specified services that in whole PLMN, on given frequency, is provided is that MBMS is professional.
2) Radio Access Network (Radio Access Network, RAN) relevant information and core network (Core Network, CN) and application layer separate.Wherein, the information relevant with RAN comprises, for example, and frequency layer, transport-type (for example whether adopting multimedia broadcasting SFN (Multimedia Broadcast Single Frequency Network, MB SFN) transmission) or assigned radio resource etc.Usually, ESG provides the application information specific.And MBSFN is the notion that belongs to Access Layer, can't be obtained by core net usually.In addition, based on certain strategy, (Multicast Coordination Entity MCE) can determine on MBSFN, not provide MBMS professional to multicast cooperation entity.And on ESG, be difficult to provide above-mentioned dynamic information.
3), then professional interested all user terminals of a certain MBMS will be reselected on the same given frequency carrier when professional time started of this MBMS if professional time started of MBMS and place frequency are provided by ESG.Then, if this MBMS business does not provide on MBSFN, for example, be that the mode with clean culture provides, then user terminal need ask to be connected with network to set up clean culture and connect that to receive this MBMS professional.Above-mentioned mechanism forces this user terminal to move on the unwanted carrier frequency, thereby causes load unbalanced.
4) in addition, also can not carry out test based on the cell reselection priority of application layer.
In order to solve the above problems, the present invention proposes a kind of method and apparatus that promotes cell reselection priority by user terminal.

Embodiment
Fig. 1 shows the systems approach flow chart according to the user terminal of a specific embodiment of the present invention.
In the present embodiment, user terminal 2 is for being in the user terminal of idle condition, and it periodically intercepts paging message, and detects the main plot.
At first in step S10, the MBMS business that base station 1 obtains from other neighbor cells provides condition information.
Hereinafter, we adjacent with base station 1 and 3 neighbor cells 3,4 and 5 be that example describes.3 neighbor cells that it will be understood by those skilled in the art that above-mentioned base station 1 are merely example.In the system configuration of reality, the neighbor cell of a base station is different from above cited 3 probably, possibly have more or less neighbor cell.
Above-mentioned steps S10 guarantees that base station 1 can immediately receive the MBMS state of affairs information of up-to-date neighbor cell 3,4 and 5; So that base station 1 generates corresponding aerial signaling interface, thereby notify the user terminal of having jurisdiction over to this base station 2 with the MBMS state of affairs information of neighbor cell.
Then, in step S11, the MBMS state of affairs information of these neighbor cells is broadcasted to user terminal 2 in base station 1 on corresponding air interface.
The MBMS state of affairs information of following at least three kinds of mode informing user terminal 2 neighbor cells can be adopted in base station 1:
-utilize system information block 4 (System Information Block 4, SIB 4) and system information block 5 (System Information Block 5, SIB 5) to carry MBMS state of affairs information;
-utilize system information block 13 to carry MBMS state of affairs information; Perhaps
-utilize multicast control channel (Multicast Control Channel; MCCH) channel bearing MBMS state of affairs information; And utilize the modification cycle (Modification Period, MP) and repetition period (Repetition Period, the position of RP) indicating MBMS state of affairs information to occur.
Wherein, this business of each neighbor cell provides condition information to comprise corresponding M BMS service identification (service ID) at least.
Then, in step S12, the MBMS business that user terminal 2 obtains a plurality of neighbor cells provides condition information, and wherein, the MBMS business of each neighbor cell provides condition information to comprise corresponding M BMS service identification at least.Therefore, user terminal 2 learns that which MBMS the neighbor cell 3,4,5 of base station 1 provides professional.User terminal 2 provides condition information to be kept at this locality the MBMS business of these a plurality of neighbor cells that obtain.
In case providing condition information to produce, the MBMS business in any in the neighbor cell 3,4,5 upgrades; Base station 1 is on obtaining after the above-mentioned renewal; Immediately above-mentioned lastest imformation is adopted one of three kinds of modes describing among the above-mentioned steps S11; Also promptly, the paging mode of SIB4/5 and SIB 13, and in MP in the MCCH message and/or the RP mode any is broadcast to user terminal 2.Then, user terminal 2 utilizes the neighbor cell MBMS business of preserving on corresponding system information or this user terminal of MCCH information updating 2 that condition information is provided.Thereby user terminal 2 perhaps monitor above-mentioned MCCH channel, thereby the neighbor cell MBMS business of obtaining on the up-to-date user terminal 2 provides condition information through monitoring system message.It will be understood by those skilled in the art that concrete which kind of mode that adopts in base station 1 provides the MBMS business of above-mentioned neighbor cell to provide condition information in network, to configure in advance to user terminal 2, and in the base station with all be known in the user terminal.
Then; In step S13; User terminal 2 is professional according to the target MBMS of this user terminal 2, the MBMS business of these a plurality of neighbor cells provides condition information and this user terminal 2 is measured respectively and the signal quality between these a plurality of neighbor cells, confirms to be used to promote the target neighbor cell of cell reselection priority.
Particularly, step S13 can be divided into following substep:
At first, in step S130, determine when and select suitable neighbor cell, promote the cell reselection priority of this neighbor cell with purpose for the MBMS business continuance.Preferably, when satisfying conventional district reselecting trigger condition, select suitable neighbor cell to promote the cell reselection priority of this neighbor cell.The district reselecting trigger condition that this is conventional; Comprise according to user terminal 2 measure respectively and the signal quality between neighbor cell 3,4 and 5, for example, Reference Signal Received Power (Reference Signal Receiving Power; RSRP) satisfy existing district reselecting criterion; For example, during the S criterion, there is the candidate neighbor cell collection that satisfies the district reselecting criterion.Therefore; Before user terminal 2 carries out the district reselecting operation; User terminal 2 can be concentrated according to the professional reception demand of the MBMS of self from this candidate neighbor cell and select suitable neighbor cell as target neighbor cell, thereby promotes this target neighbor cell gravity treatment priority.Because this target neighbor cell choose the cell reselection rules that has satisfied existing conventional based on signal quality, so guaranteed the communication quality on this target re-selecting cell that user terminal 2 is follow-up for the professional and possible unicast service of MBMS.
Confirmed when select suitable neighbor cell at step S130 with purpose for the MBMS business continuance; After promoting the cell reselection priority of this neighbor cell; In step S131; User terminal 2 is according to predetermined rule, and how concrete realization selects suitable neighbor cell with the purpose for the MBMS business continuance, promotes the cell reselection priority of this neighbor cell.
Particularly, this target MBMS business comprises the MBMS business that MBMS is professional or this user terminal 2 is hoped reception that this user terminal 2 is receiving.According to certain strategy, when user terminal 2 had the MBMS that is receiving professional, user terminal 2 was professional according to this MBMS that is receiving, and promotes the operation of cell reselection priority; When the MBMS that is hopeful to receive when user terminal 2 was professional, user terminal 2 hoped that according to this MBMS that receives is professional, promotes the operation of cell reselection priority; The 2 existing MBMS that receiving are professional when user terminal; When the MBMS that is hopeful again to receive was professional, in order to keep receiving the professional continuity of MBMS, user terminal 2 for example; Can select to promote the operation of cell reselection priority according to the MBMS business that is receiving.
User terminal 2 is professional based on the target MBMS of user terminal 2, a plurality of neighbor cells 3,4 and 5 MBMS business provide condition information; And user terminal 2 measure respectively and the signal quality between these a plurality of neighbor cells 3,4 and 5, confirm to be used to promote the target neighbor cell of cell reselection priority.For example, the MBMS service identification that user terminal 2 is receiving is MBMS a, and the MBMS that neighbor cell 3 provided is professional to be a and b, and the MBMS that neighbor cell 4 provided is professional to be b and c, and the MBMS business that neighbor cell 5 provided is a and c.And neighbor cell 3,4 and 5 is according to the determined candidate's re-selecting cell of the cell reselection rules of routine collection.User terminal 2 measure respectively and neighbor cell 3,4, the signal quality between 5 be-85dBm ,-90dBm and-75dBm.Because the signal quality between that user terminal 2 is measured and the neighbor cell 5 is best; And the professional a of the MBMS that neighbor cell 5 provides user terminal 2 receiving; Therefore, with neighbor cell 5 as target neighbor cell, to promote the cell reselection priority of this target neighbor cell.It will be appreciated by those skilled in the art that; Numerical value and sequence number among above-mentioned each embodiment are merely example; In the system configuration of reality; The numerical value of the signal quality of the neighbor cell that user terminal is measured is not limited to above-mentioned example, and the MBMS business that the needed MBMS business of user terminal and neighbor cell can provide also is not limited thereto.
In another embodiment;, a plurality of neighbor cells 3,4 professional except the target MBMS that considers user terminal 2 and 5 MBMS business provide condition information; And this user terminal 2 measure respectively and outside the signal quality between these a plurality of neighbor cells 3,4 and 5; It is also conceivable that the frequency at neighbor cell place, carry out the lifting of cell reselection priority.Below, it is bright specifically with Fig. 3 to be that example is carried out.
At first, in step S30, user terminal 2 is according to the service priority of self, and the MBMS that ordering user terminal 2 is receiving is professional or hope that the MBMS that receives is professional.For example, user terminal 2 possibly have the MBMS business that the professional and/or one or more hope of one or more MBMS that receiving receive.The professional priority of these MBMS is different.User terminal 2 is at first professional to the MBMS that receiving, sorts according to from high to low priority, and then the professional priority of MBMS that hope receives is sorted.User terminal 2 at first to the MBMS that receiving according to its service priority order from high to low, promote the operation of cell reselection priority successively; And then professional to the MBMS that hopes to receive, according to its service priority order from high to low, promote the operation of cell reselection priority successively.
Then, promote the MBMS business of the operation of cell reselection priority to some specific needs, user terminal 2 is operated as follows again:
Cell reselection priority is 1-7, and numerical value is high more, and the gravity treatment priority of representative is high more.Also promptly, user terminal 2 judges earlier whether the professional neighbor cell of the MBMS that MBMS is professional or hope receives that provides user terminal 2 receiving is arranged in the neighbor cell with limit priority 7.If in the highest gravity treatment priority 7, do not have neighbor cell to satisfy condition; Judge successively then gravity treatment priority is whether to have the neighbor cell that satisfies condition in 6,5,4,3,2,1 the neighbor cell; If exist; Then with the neighbor cell that satisfies condition as target neighbor cell, the gravity treatment priority of this target neighbor cell promoted be limit priority 7.
Then, in step S31, user terminal 2 judges according to the frequency information of neighbor cell 3,4 and 5 whether the professional neighbor cell of the MBMS that MBMS is professional or hope receives that provides user terminal 2 receiving is arranged in the homogeneous frequency adjacent area tabulation.
Then, in step S32, the homogeneous frequency adjacent area that user terminal 2 judges whether to satisfy above-mentioned condition is positioned at the candidate neighbor cell that satisfies conventional district reselecting criterion and concentrates.
If not, then this method gets into step S33, and user terminal 2 continuation judge whether the professional neighbor cell of MBMS that the MBMS that provides user terminal 2 receiving is professional or hope reception is arranged in the alien frequencies neighbor cell list.
If the judged result of step S33 is for being, then the user terminal 2 alien frequencies neighbor cell that in step S34, further judges whether to satisfy above-mentioned condition is positioned at the candidate neighbor cell that satisfies conventional district reselecting criterion and concentrates.
If the judged result of step S34 is for being, then this method gets into step S35, and as target neighbor cell, also promptly, the gravity treatment priority of this target neighbor cell is set to the highest by 7 with the same frequency that satisfies condition or alien frequencies neighbor cell.
If the judged result of step S34 is not, then this method gets into step S36, does not have the target neighbor cell that can promote gravity treatment priority.
If the judged result of step S32 is for being, then this method gets into step S35, and as target neighbor cell, also promptly, the gravity treatment priority of this target neighbor cell is set to the highest by 7 with the same frequency that satisfies condition or alien frequencies neighbor cell.
In the foregoing description; User terminal 2 at first the target MBMS at judges terminal 2 professional with the homogeneous frequency adjacent area tabulation in the MBMS business of neighbor cell whether mate; If the neighbor cell of coupling is arranged then; Whether the neighbor cell of judging this coupling again appears in candidate's re-selecting cell tabulation of satisfying S criterion and R criterion, thereby determines whether to exist needs to promote the neighbor cell of gravity treatment priority.Above-mentioned order is adjustable.For example; At first the target MBMS at judges terminal 2 is professional whether neighbor cell provided in tabulating with the candidate's re-selecting cell that satisfies S criterion and R criterion MBMS business matees for user terminal 2; Then; In the neighbor cell of coupling, judge whether to exist co-frequency cell again, judge whether to exist alien-frequency district at last again.
Even it will be understood by those skilled in the art that to have identical state, the user terminal that different vendor produces confirms probably that according to its algorithm separately different target neighbor cell promotes the operation of gravity treatment priority.But,, only effective to this particular user terminal because the operation of the determined lifting gravity treatment of user terminal priority is exclusively used in each user terminal.Therefore, can not exert an influence to other user terminals.
In addition, might there be the suitable target neighbor cell that can promote gravity treatment priority (step S35).Then user terminal 2 can't be confirmed to be used to keep the MBMS business continuance to be used to promote the target neighbor cell of cell reselection priority.And this result can not influence the district reselecting of the routine of user terminal 2 yet.User terminal 2 still can carry out conventional district reselecting according to original parameter.
Then, in step S14, user terminal 2 promotes the gravity treatment priority of this target neighbor cell.
User terminal 2 can adopt any or boths' in the following dual mode combination to promote the cell reselection priority of selected target neighbor cell.
Mode one:
After step S131 had confirmed target neighbor cell, the gravity treatment priority of the target neighbor cell that user terminal 2 will be confirmed immediately promoted and is limit priority, also is 7.
This mode is suitable for user terminal 2 and is receiving the professional instance of MBMS.If user terminal 2 is made the decision of gravity treatment priority based on the MBMS business of its current reception, then preferably should carry out the cell reselection priority that promotes this target neighbor cell of choosing immediately.After user terminal 2 has been carried out the district reselecting operation immediately, minimum to the MBMS service impact that user terminal 2 is receiving.
But for those is not that ongoing MBMS is professional; This mode possibly be otiose; Because user terminal hopes that the MBMS business that receives not is that the current MBMS that is receiving is professional, does not have help and carry out district reselecting immediately to the professional continuity of MBMS that is receiving.Certainly, subsequently, the MBMS business of neighbor cell provides condition information to upgrade, and therefore, user terminal 2 also can correspondingly change definite result of its cell reselection priority, thereby the selection result of target neighbor cell also can change.
Mode two:
After step S131 has confirmed target neighbor cell, promote and be limit priority in the name a person for a particular job gravity treatment priority of this target neighbor cell of confirming of preset time, also promptly 7.
This mode is suitable for user terminal 2 will hope to receive the MBMS business as the professional instance of target MBMS.Also promptly, user terminal 2 is made the decision of gravity treatment priority based on the MBMS business of its hope reception.
User terminal 2 can MBMS in this electronic program guides, that this user terminal 2 hopes to receive are professional time started as this preset time point, and promote the gravity treatment priority of this target neighbor cell during in professional time started of this MBMS or near the time started.Certainly; Before user terminal 2 is hoped the professional arrival of the MBMS that receives; The gravity treatment priority of possible neighbor cell promotes the result and also can change; Then user terminal 2 is selected to promote the result near the neighbor cell gravity treatment priority of professional time started of this MBMS that hopes to receive, the gravity treatment priority of this neighbor cell is promoted be limit priority.
Aforesaid way one also can combine with mode two.User terminal 2 can be to receive the MBMS business or hoping to receive the MBMS business according to this user terminal 2, promotes the selected target neighbor cell that is used to promote gravity treatment priority to determine when.
Notice; For present MBMS model and/or notion; The MBMS business datum is only with MBSFN mode multicast data transmission, and the professional guide information of MBMS of ESG broadcasting is not considered this MBMS business transmission means of interface aloft, is yet; The MBMS business of ESG broadcasting possibly be to transmit with the MBSFN mode, also possibly be the mode of unicast transmission.Also promptly mean; Even MBMS business of broadcasting on ESG, this MBMS business possibly not provide on the MBSFN zone yet, therefore; If this MBMS business does not provide on the MBSFN zone, user terminal 2 should not promote the gravity treatment priority of this corresponding neighbor cell.
Particularly, the professional time started of MBMS is indicated by ESG.Whether this MBMS business transmits with the MBSFN mode on this target neighbor cell that then (Radio Resource Control, RRC) signaling offers user terminal 2 through Radio Resource control.Determine whether on MB SFN, to provide MBMS professional by MCE (RAN node).Whether user terminal 2 provides the MBMS business to transmit with the MBSFN mode according to professional time started of MBMS and the RRC signaling that ESG provides, and determines whether to promote the gravity treatment priority of Target cell.
User terminal 2 judges whether MBMS business among this ESG, that user terminal 2 hope receive is provided with the MBSFN transmission means by this target neighbor cell;
-when among this ESG, user terminal 2 hopes that the MBMS business that receive are when being provided with the MBSFN transmission means by this target neighbor cell; Professional time started of MBMS will be in this ESG, that this user terminal 2 hopes to receive is as this preset time point, and promotes the gravity treatment priority of this target neighbor cell in the professional time started of this MBMS.Otherwise user terminal 2 does not promote the gravity treatment priority of this neighbor cell.
