Description
Technical field
The present invention relates to machine-type communication system, the paging method of MTC UE strengthened particularly for coverage and device.
Background technology
Machine-type communication (Machine Type Communication, MTC) equipment is the subscriber equipment for application-specific (UE) used by machine.One example of this MTC device is intelligence instrument.Some in these intelligence instruments are likely located at basement, and it is subjected to higher penetration loss, and therefore MTC device is difficult to communicate with network.Therefore, 3GPP is for expanding the coverage area and effort, it is intended to the coverage of MTC UE is expanded 15dB.Hereinafter, this UE that can run in coverage enhancement region (coverage enhanced region) is referred to as the MTC UE that coverage strengthens.
It is the Main Means of coverage for improving MTC UE that the repeating of physical channel is transmitted.Number of retransmissions is the highest, and such as 100 times, this will seriously reduce spectrum efficiency.Repeat to be used for Common transport channel and the dedicated transmission channel of PDSCH.When paging, owing to repeating to stride across multiple calling time, the most this repetition is difficult to dispersion paging load.
In existing paging, UE uses following formula (1) and (2) to determine paging frame (paging frame) and calling time (paging occasion) thus determines when it needs the monitoring PDCCH that wakes up.If UE listens to carry on PDCCH P-RNTI, then on corresponding PDSCH channel, obtain beep-page message.In existing paging, only using a P-RNTI to indicate has beep-page message in subframe.
SFN mod T=(T div N) * (UE_ID mod N) (1)
Wherein, SFN represent the paging for UE, mod may be had in the frame to represent modulo operation, div represent divides exactly computing.
I_s=floor (UE_ID/N) mod Ns (2)
Wherein, index i_s points to the calling time (paging subframe) in subframe pattern, and noor represents downward rounding operation, and mod represents modulo operation.
Wherein:
-T represents discontinuous reception (DRX) cycle of UE；
-nB:4T, 2T, T, T/2, T/4, T/8, T/16, T/32；
-N:min (T, nB)；
-Ns:max (1, nB/T)；
-UE_ID:IMSI mod1024.
The left side display paging SFN of formula (1) will occur every T wireless frame period.The right side display offset of formula (1) and this skew have granularity (T div N), it means that the granularity of skew can be to 32 radio frames from 1 radio frames.(UE_ID mod N) for being grouped into different skews by UEs.If N=T=64, then in that UE will be placed in 64 possible skews.If N=T/32=2, then in that UE will be placed in 2 skews.
As shown in the table, if N=T, then if T=64, then the possible paging frame of UE will be paging frame 0 ..., in 63}.Therefore, paging load will be dispersed in 64 radio frames.If N=nB, then if the possible paging frame of T=64, UE will depend upon which nB and its mark (UE_ID).
The right side of formula (2) is the index to following table.When nB is T or is less than T, it is 0 or 1 that i_s is only capable of, and Ns=1.When nB is more than T (that is, 2T or 4T), i_s can also value 2 and 3.
| Ns | PO works as i_s=0 | PO works as i_s=1 | PO works as i_s=2 | PO works as i_s=3 |

Summary of the invention
The UE strengthened for coverage, in order to repeat to transmit beep-page message, N must be arranged to smaller value (that is, N=T/32).N=T/32 will provide 128 frames (4*32 radio frames) to be used for repeating, and this is enough for repeating in strengthening region in the coverage of 15dB.But, this will imply that network/operator will be unable to dispersion paging load on paging cycle.When there is the UE that many coverages strengthen in the cell, use little N value cannot make us accepting from the perspective of paging load.Additionally, paging load needs to share with existing UE.
For coverage strengthen UE, if using any N value (such as, a bigger N value that can disperse paging load), then paging repeat transmit it may happen that overlap, as shown in Figure 1.In FIG, T=64, that is, the DRX cycle of 64 radio frames, N=T/8=8, that is, each calling time is separated by 8 radio frames, thus reach the load of 12.5%.As shown in Figure 1, it is considered to the paging that two calling times (PO1 and PO2) and PDCCH carry needs to repeat for 16 times, it can be seen that repeat overlap in time.
It is therefore proposed that a kind of new technical scheme that can solve the problem that the problems referred to above is the most necessary.

Detailed description of the invention
As described above, the basic thought of the present invention is: be different from prior art an only P-RNTI (value FFFE), the present invention introduces multiple different P-RNTI, multiple MTC UE in coverage enhancement region belong at least one packet, the allocated P-RNTI corresponding to this packet of each packet, such as, all MTC UE in first packet are corresponding to the P-RNTI in the plurality of different P-RNTI, and all MTC UE in the second packet are corresponding to the 2nd P-RNTI in the plurality of different P-RNTI.Running time-frequency resources different in each P-RNTI instruction paging frame in the plurality of different P-RNTI, it is possible to be dispersed on different running time-frequency resources paging load.
Owing to the present invention introducing multiple different P-RNTI, therefore, before carrying out paging, the MTC UE side either still strengthened in coverage in base station side, it is required for determining the P-RNTI corresponding to this MTC UE.
From the point of view of MTC UE side, with reference to Fig. 2, in step 201, the MTC UE that coverage strengthens, based on special parameter, determines the P-RNTI corresponding to this UE.This special parameter can be that this coverage strengthens the UE_ID of MTC UE, the levels of repetition of paging or a combination thereof.
In fact, this special parameter is exactly that the MTC UE that strengthens of multiple coverage belongs to the reference factor of different grouping, such as, when special parameter is UE_ID, the UE_ID of some the MTC UE in the MTC UE that multiple coverages strengthen belongs to a packet, and the UE_ID of other MTC UE belongs to another packet.It is understandable that, it is only exemplary and not exhaustive that coverage mentioned above strengthen the UE_ID of MTC UE and/or the levels of repetition of paging etc. to be grouped the reference factor being based on, it will be understood by those skilled in the art that the special parameter determining packet of other suitable type is readily adaptable for use in the design of the present invention.
In one embodiment, as the UE_ID that special parameter is the MTC UE that coverage strengthens, the MTC UE that this coverage strengthens can be based on initial RNTI value, value range Range and the UE_ID of this MTC UE, and according to below equation, determines the P-RNTI corresponding to this MTC UE:
P-RNTI=initiates RNTI value+(UE_ID mod (Range-1))
Wherein, mod represents modulo operation, and Range is integer and is not less than 2.
For value range Range, can be configured by system and be transmitted in the way of such as broadcasting by base station.
For initial RNTI value, UE side can be stored in advance in, or this MTC UE can also be sent to by base station.
For UE_ID, can determine for calculating the UE identification index of paging frame based on what Mobility Management Entity (MME) provided.
It is understood that in the present embodiment, as Range=2, the MTC UE, an only P-RNTI that whole multiple coverages are strengthened.In other words, in whole multiple MTC UE are divided into a group.
In another embodiment, as the UE_ID that special parameter is the MTC UE that coverage strengthens, the MTC UE that this coverage strengthens is also based on the UE_ID of this MTC UE, and according to below equation, from N number of RNTI{RNTI [1], RNTI [2] ..., RNTI [N] in select corresponding to the P-RNTI of this MTC UE:
P-RNTI=RNTI [n], n=UE_ID mod (N-1)
Wherein, described mod represents modulo operation.
Such as, in this MTC UE side, the mapping relations table of n value and RNTI [n] value can be previously stored with.When the n value calculated if based on UE_ID is 1, the value of RNTI [n] corresponding with n=1 in mapping relations table is the P-RNTI value of this MTC UE.
In yet another embodiment, when predefined parameter is levels of repetition, the MTC UE that this coverage strengthens can be based on initial RNTI value and the call number of levels of repetition, and according to below equation, determines the P-RNTI corresponding to this MTC UE:
P-RNTI=initiates the call number of RNTI value+levels of repetition
It is understood that following corresponding relation can be there is between levels of repetition and its call number: a kind of levels of repetition is corresponding to a kind of call number, or multiple levels of repetition is corresponding to a kind of call number.
The call number of levels of repetition can be such as from the beginning of 0.It is, of course, understood that this call number can also be from the beginning of the numerical value not being 0.
In the present embodiment, in fact it could happen that the levels of repetition of MTC UE changes and situation that base station is not aware that.Based on this, when the levels of repetition of MTC UE changes, it can send one and ask to base station, for asking base station to update the levels of repetition corresponding to this MTC UE of base station side.So, base station can determine the P-RNTI of this MTC UE based on the levels of repetition of this MTC UE after updating.
Or, an intervalometer can be used to carry out timing in base station side, when timing arrives predetermined value, base station i.e. knows that the levels of repetition of this MTC UE is changed to another value, then base station can determine the P-RNTI of this MTC UE based on the levels of repetition of this MTC UE after updating.
Or, due to base station the current levels of repetition of this MTC UE uncertain, therefore, base station can also obtain different P-RNTI based on different paging grades and carry out paging respectively.
It is understood that in this embodiment, the levels of repetition of MTC UE can also store in the core network, and when this MTC UE needs paged, core net indicates levels of repetition to base station.
Then, in step 202., the MTC UE that coverage strengthens monitors PDCCH at the calling time of paging frame.
Paging frame and calling time can use existing above-mentioned formula (1) and (2) in prior art to calculate.
Advantageously, paging frame based on levels of repetition K, and can also calculate according to following formula:
SFN mod T=(T DIV (N/K)) * (UE_ID mod (N/K))
As such, it is possible to preferably disperse paging load.
Then, in step 203, if carrying the P-RNTI of above-mentioned this MTC UE determined on this PDCCH, then the running time-frequency resource that the MTC UE that coverage strengthens indicates based on this PDCCH, corresponding PDSCH obtains beep-page message.
From the point of view of base station side, when it needs to send beep-page message to the MTC UE that certain coverage strengthens, this base station needs based on special parameter, determines the P-RNTI corresponding to this MTC UE；Then, at the calling time of paging frame, send the PDCCH carrying this P-RNTI, and send beep-page message on the running time-frequency resource of the PDSCH indicated at this PDCCH.
Based on special parameter, base station determines that the method for P-RNTI corresponding to this MTC UE is similar with the method that above-mentioned UE side describes, for simplicity's sake, therefore not to repeat here.
Advantageously, moreover, paging frame based on levels of repetition K, and can also calculate according to following formula:
SFN mod T=(T DIV (N/K)) * (UE_ID mod (N/K))
It should be noted that in communication system based on machine-type communication, when P-RNTI based on the present invention is used, the MTC UE that coverage strengthens should ignore the P-RNTI (value is FFFE) for existing UE.
