1) MBMS should be transmitted in the frequency indicated by ESG.ESG normally considers application layer message and carries out formaing, and for all effective in whole public land mobile net (Public Land Mobile Network, PLMN) or larger geographic area.Therefore, be difficult to guarantee that ESG specified services provided on the given frequency in whole PLMN is MBMS.
2) Radio Access Network (Radio Access Network, RAN) relevant information and core network (Core Network, CN) and application layer are separated.Wherein, the information relevant to RAN comprises, such as, frequency layer, transport-type (such as whether adopting multimedia broadcasting single frequency network (Multimedia Broadcast Single Frequency Network, MB SFN) to transmit) or distribute Radio Resource etc.Usually, ESG provides the specific information of application.And MBSFN is the concept belonging to Access Layer, usually cannot be obtained by core net.In addition, based on certain strategy, multicast cooperation entity (Multicast Coordination Entity, MCE) can determine on MBSFN, not provide MBMS.And be difficult to provide above-mentioned dynamic information on ESG.
3) if provided time started and the place frequency of MBMS by ESG, then the interested all user terminals of a certain MBMS will be reselected on same given frequency carrier when the time started of this MBMS.Then, if this MBMS does not provide on MBSFN, such as, be provide in the mode of clean culture, then user terminal need request connected to the network with set up clean culture connect receive this MBMS.Above-mentioned mechanism forces this user terminal to move on unwanted carrier frequency, thus causes load imbalance.
4) test of the cell reselection priority based on application layer can not in addition, also be carried out.
In order to solve the above problems, the present invention proposes a kind of method and apparatus being promoted cell reselection priority by user terminal.

Embodiment
Fig. 1 shows the systems approach flow chart of the user terminal according to 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 main plot.
First in step slo, the MBMS that base station 1 obtains from other neighbor cells provides condition information.
Hereinafter, we to be adjacently described for base station 1 and 3 neighbor cells 3,4 and 5.It will be understood by those skilled in the art that 3 neighbor cells of above-mentioned base station 1 are only example.In the system configuration of reality, the neighbor cell of a base station is probably different from above cited 3, may have more or less neighbor cell.
Above-mentioned steps S10 guarantees that base station 1 immediately can receive the MBMS condition information of up-to-date neighbor cell 3,4 and 5; so that base station 1 generates corresponding aerial signaling interface, thus the MBMS condition information of neighbor cell is informed to the administrative user terminal in this base station 2.
Then, in step s 11, the MBMS condition information of this neighbor cell is broadcasted in base station 1 in corresponding air interface to user terminal 2.
Base station 1 can adopt the MBMS condition information of at least following three kinds of mode informing user terminal 2 neighbor cells:
-utilize system information block 4 (System Information Block 4, SIB 4) and system information block 5 (System Information Block 5, SIB 5) bearing MBMS service condition information;
-utilize system information block 13 bearing MBMS service condition information; Or
-utilize multicast control channel (Multicast Control Channel, MCCH) channel bearing MBMS condition information, and utilize amendment cycle (Modification Period, and repetition period (Repetition Period, the RP) position that indicates MBMS condition information to occur MP).
Wherein, this business of each neighbor cell provides condition information at least to comprise corresponding MBMS mark (service ID).
Then, in step s 12, the MBMS that user terminal 2 obtains multiple neighbor cell provides condition information, and wherein, the MBMS of each neighbor cell provides condition information at least to comprise corresponding MBMS mark.Therefore, user terminal 2 learns which MBMS the neighbor cell 3,4,5 of base station 1 provides.The MBMS of multiple neighbor cells of this acquisition provides condition information to be kept at this locality by user terminal 2.
Upgrade once the MBMS in any one in neighbor cell 3,4,5 provides condition information to produce, base station 1 is in acquisition after above-mentioned renewal, immediately above-mentioned lastest imformation is adopted one of three kinds of modes described in above-mentioned steps S11, also be, the paging mode of SIB4/5 and SIB 13, and any one in MP and/or RP mode in MCCH message is broadcast to user terminal 2.Then, user terminal 2 utilizes the neighbor cell MBMS that corresponding system information or this user terminal of MCCH information updating 2 are preserved to provide condition information.Thus user terminal 2 by monitoring system message, or monitors above-mentioned MCCH channel, thus the neighbor cell MBMS obtained on up-to-date user terminal 2 provides condition information.It will be understood by those skilled in the art which kind of mode base station 1 specifically adopts provide the MBMS of above-mentioned neighbor cell to provide condition information to configure in a network in advance to user terminal 2, and in a base station be all known in user terminal.
Then, in step s 13, the signal quality respectively and between the plurality of neighbor cell that user terminal 2 provides condition information and this user terminal 2 to measure according to the target MBMS of this user terminal 2, the MBMS of the plurality of neighbor cell, determines the target neighbor cell promoting cell reselection priority.
Particularly, step S13 can be divided into following sub-step:
First, in step s 130, which, determine when to select suitable neighbor cell with the object in order to MBMS service continuity, promote the cell reselection priority of this neighbor cell.Preferably, when the cell reselection trigger condition of satisfied routine, select suitable neighbor cell to promote the cell reselection priority of this neighbor cell.The cell reselection trigger condition of this routine, comprise according to user terminal 2 measure respectively and neighbor cell 3, signal quality between 4 and 5, such as, Reference Signal Received Power (Reference Signal Receiving Power, RSRP) existing cell reselection criterion is met, such as, during S criterion, there is the candidate neighbor cell collection meeting cell reselection criterion.Therefore, before user terminal 2 carries out cell reselection operation, user terminal 2 can be concentrated from this candidate neighbor cell and select suitable neighbor cell as target neighbor cell according to the MBMS reception demand of self, thus promotes this target neighbor cell gravity treatment priority.Because this target neighbor cell choose the cell reselection rules based on signal quality meeting existing routine, so ensure that the communication quality for MBMS and possible unicast service on this target re-selecting cell that user terminal 2 is follow-up.
When determine in step S130 selects suitable neighbor cell with the object in order to MBMS service continuity, after promoting the cell reselection priority of this neighbor cell, in step S131, user terminal 2 is according to predetermined rule, how specific implementation selects suitable neighbor cell with the object in order to MBMS service continuity, promotes the cell reselection priority of this neighbor cell.
Particularly, this target MBMS comprises the MBMS that MBMS that this user terminal 2 receiving or this user terminal 2 wish to receive.According to certain strategy, when user terminal 2 has the MBMS received, the MBMS that user terminal 2 is receiving according to this, carries out the operation promoting cell reselection priority; When user terminal 2 is hopeful the MBMS received, the MBMS that user terminal 2 receives according to this hope, carries out the operation promoting cell reselection priority; The MBMS received when user terminal 2 is existing, when being hopeful again the MBMS received, in order to keep the continuity receiving MBMS, user terminal 2 such as, the MBMS according to receiving can being selected, carrying out the operation promoting cell reselection priority.
User terminal 2 provides condition information based on the MBMS of the target MBMS of user terminal 2, multiple neighbor cell 3,4 and 5, and user terminal 2 measure respectively and the plurality of neighbor cell 3, signal quality between 4 and 5, determine the target neighbor cell promoting cell reselection priority.Such as, the MBMS that user terminal 2 is receiving is designated MBMS a, and the MBMS that neighbor cell 3 provides is a and b, and the MBMS that neighbor cell 4 provides is b and c, and the MBMS that neighbor cell 5 provides is a and c.And neighbor cell 3,4 and 5 is according to the cell reselection rules of routine determined candidate re-selecting cell collection.The signal quality respectively and between neighbor cell 3,4,5 that user terminal 2 is measured is-85dBm ,-90dBm and-75dBm.Because that user terminal 2 is measured and between neighbor cell 5 signal quality is best, and the MBMS a that neighbor cell 5 provides user terminal 2 receiving, therefore, using 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 in each embodiment above-mentioned and sequence number are only example, in the system configuration of reality, the numerical value of the signal quality of the neighbor cell measured by user terminal is not limited to above-mentioned example, and the MBMS that MBMS required for user terminal and neighbor cell can provide also is not limited thereto.
In another embodiment, except the consideration target MBMS of user terminal 2, the MBMS of multiple neighbor cell 3,4 and 5 provide condition information, and this user terminal 2 measure respectively and the plurality of neighbor cell 3, outside signal quality between 4 and 5, it is also conceivable to the frequency at place, neighbor cell, carry out the lifting of cell reselection priority.Below, be specifically described for Fig. 3.
First, in step s 30, user terminal 2 according to the service priority of self, the MBMS that ordering user terminal 2 is receiving or wish receive MBMS.Such as, user terminal 2 may have the MBMS that one or more MBMS of receiving and/or one or more hope receive.The priority of these MBMS is different.User terminal 2, first to the MBMS received, sorts according to priority from high to low, and then sorts to the priority of the MBMS that hope receives.User terminal 2 first for the MBMS received according to its service priority order from high to low, carry out successively promoting the operation of cell reselection priority; And then for the MBMS that hope receives, according to its service priority order from high to low, carry out the operation promoting cell reselection priority successively.
Then, carry out the MBMS of the operation promoting cell reselection priority for some specific needs, user terminal 2 proceeds as follows again:
Cell reselection priority is 1-7, and numerical value is higher, and representative gravity treatment priority is higher.Also namely, user terminal 2 first judges to have in the neighbor cell of limit priority 7 MBMS whether having and provide user terminal 2 receiving or the neighbor cell of wishing the MBMS received.If do not have neighbor cell to satisfy condition in the highest gravity treatment priority 7, then judge gravity treatment priority is whether there is the neighbor cell satisfied condition in the neighbor cell of 6,5,4,3,2,1 successively, if existed, then using the neighbor cell that satisfies condition as target neighbor cell, be limit priority 7 by the gravity treatment priority promotion of this target neighbor cell.
Then, in step S31, user terminal 2, according to the frequency information of neighbor cell 3,4 and 5, judges in the list of homogeneous frequency adjacent area, whether have the MBMS providing user terminal 2 receiving or the neighbor cell of wishing the MBMS received.
Then, in step s 32, the homogeneous frequency adjacent area that user terminal 2 judges whether to meet above-mentioned condition is positioned at the candidate neighbor cell meeting conventional cell reselection criterion and concentrates.
If not, then the method enters step S33, and user terminal 2 continues to judge in alien frequencies neighbor cell list, whether have the MBMS providing user terminal 2 receiving or the neighbor cell of wishing the MBMS received.
If the judged result of step S33 is yes, then the alien frequencies neighbor cell that user terminal 2 judges whether to meet above-mentioned condition further in step S34 is positioned at the candidate neighbor cell meeting conventional cell reselection criterion and concentrates.
If the judged result of step S34 is yes, then the method enters step S35, using the same frequency that satisfies condition or alien frequencies neighbor cell as target neighbor cell, also, the gravity treatment priority of this target neighbor cell is set to the highest 7.
If the judged result of step S34 is no, then the method enters step S36, there is not the target neighbor cell that can promote gravity treatment priority.
If the judged result of step S32 is yes, then the method enters step S35, using the same frequency that satisfies condition or alien frequencies neighbor cell as target neighbor cell, also, the gravity treatment priority of this target neighbor cell is set to the highest 7.
In above-described embodiment, first user terminal 2 judges whether the target MBMS of user terminal 2 mates with the MBMS of the neighbor cell in the list of homogeneous frequency adjacent area, if then there is the neighbor cell of coupling, judge whether the neighbor cell of this coupling appears at again to meet in the candidate re-selecting cell list of S criterion and R criterion, thus determine whether there is the neighbor cell needing to promote gravity treatment priority.Above-mentioned order is adjustable.Such as, first user terminal 2 can judge whether the MBMS that the target MBMS of user terminal 2 and neighbor cell in the candidate re-selecting cell list meeting S criterion and R criterion provide mates, then, in the neighbor cell of coupling, judge whether to there is co-frequency cell again, finally judge whether to there is alien-frequency district again.
Even if it will be understood by those skilled in the art that to have identical state, the user terminal that different vendor produces, according to its respective algorithm, probably determines that the operation of gravity treatment priority is carried out promoting in different target neighbor cell.But, because the operation of user terminal determined lifting gravity treatment priority is exclusively used in each user terminal, only effective to this specific user terminal.Therefore, can not have an impact to other user terminals.
In addition, likely there is not the suitable target neighbor cell (step S35) that can promote gravity treatment priority.Then user terminal 2 cannot determine keeping MBMS service continuity for the target neighbor cell promoting cell reselection priority.And this result also can not affect the cell reselection of the routine of user terminal 2.User terminal 2 still can carry out conventional cell reselection 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 the combination of any one or both in following two kinds of modes to promote the cell reselection priority of selected target neighbor cell.
Mode one:
After step S131 determines target neighbor cell, the gravity treatment priority promotion of the target neighbor cell that this determines by user terminal 2 is immediately limit priority, is also 7.
Which is suitable for the example that user terminal 2 is receiving MBMS.If user terminal 2 makes the decision of gravity treatment priority based on the MBMS of its current reception, then preferably should perform the cell reselection priority promoting this target neighbor cell chosen immediately.After user terminal 2 performs cell reselection operation immediately, the MBMS impact received user terminal 2 is minimum.
But not ongoing MBMS for those, which may be otiose, because user terminal wishes that the MBMS received not is the current MBMS received, and perform the continuity of cell reselection to the MBMS received immediately and do not have help.Certainly, subsequently, the MBMS of neighbor cell provides condition information to upgrade, and therefore, user terminal 2 also correspondingly can change the determination result of its cell reselection priority, thus the selection result of target neighbor cell also can change.
Mode two:
After step S131 determines target neighbor cell, the gravity treatment priority promotion putting the target neighbor cell this determined in predetermined time is limit priority, is also 7.
Which is suitable for user terminal 2 and hope is received the example of MBMS as target MBMS.Also namely, based on it, user terminal 2 wishes that the MBMS received is made gravity treatment priority and determined.
User terminal 2 can using in this electronic program guides, this user terminal 2 wishes that the time started of the MBMS received as this some predetermined time, and in the time started of this MBMS or close to the gravity treatment priority promoting this target neighbor cell during the time started.Certainly, before user terminal 2 wishes that the MBMS received arrives, the gravity treatment priority promotion result of possible neighbor cell also can change, then user terminal 2 selects the neighbor cell gravity treatment priority promotion result of the time started of the MBMS received closest to this hope, is limit priority by the gravity treatment priority promotion of this neighbor cell.
Aforesaid way one and mode two also can combine.User terminal 2 can be receiving MBMS or wishing to receive MBMS according to this user terminal 2, to determine when to promote the selected target neighbor cell for promoting gravity treatment priority.
Notice, for current MBMS model and/or concept, MBMS data is only with MBSFN mode multicast data transmission, and the guide information of MBMS of ESG broadcast does not consider the transmission means of this MBMS aloft interface, also be, the MBMS of ESG broadcast may be transmit in MBSFN mode, also may be mode of unicast transmission.Also namely mean, even if broadcast a MBMS on ESG, this MBMS also may not provide on MBSFN region, therefore, if this MBMS does not provide on MBSFN region, user terminal 2 should not promote the gravity treatment priority of the neighbor cell of this correspondence.
Particularly, the time started of MBMS is indicated by ESG.Whether this MBMS is transmitted in MBSFN mode on this target neighbor cell is then supplied to user terminal 2 by wireless heterogeneous networks (Radio Resource Control, RRC) signaling.Determined whether to provide MBMS on MB SFN by MCE (RAN node).Whether the MBMS time started that user terminal 2 provides according to ESG and RRC signaling provide MBMS to transmit in MBSFN mode, determine whether the gravity treatment priority promoting Target cell.
User terminal 2 judges that in this ESG, user terminal 2 wishes whether the MBMS received is provided with MBSFN transmission means by this target neighbor cell;
-when in this ESG, user terminal 2 wish receive MBMS be provided with MBSFN transmission means by this target neighbor cell time, using in this ESG, this user terminal 2 wishes that the time started of the MBMS received is as this some predetermined time, and promotes the gravity treatment priority of this target neighbor cell in the time started of this MBMS.Otherwise user terminal 2 does not promote the gravity treatment priority of this neighbor cell.
