Specific embodiment
The embodiment of the present application provides terminal device localization method, for realizing the positioning of terminal device in NB-IoT.Present invention also provides the relevant network equipments, will be illustrated respectively below.
NB-IoT can be deployed directly into GSM network, UMTS network or LTE network, with mobility management entity (the Mobility Management Entity being multiplexed in existing network, MME), the network elements such as E-SMLC, eNB, LMU reduce lower deployment cost, realize smooth upgrade.Fig. 1 (a) is a schematic diagram of the network architecture of NB-IoT, wherein UE passes through evolved base station (evolved NodeB, eNB) core network access, and then Internet of Things (Internet of Things, IoT) platform is accessed, realize the various industries application of IoT.
A variety of applications of IoT are required to carry out precise positioning to UE.Since SRS signal being not present in NB-IoT, therefore it can not directly be multiplexed the method positioned in existing LTE to UE.For this purpose, this application provides a kind of new terminal device localization method, for being positioned using the NPRACH signal in NB-IoT to UE.
NPRACH is the random access channel of NB-IoT.The transmission resource for please referring to Fig. 1 (b): NPRACH signal can be divided into multiple NPRACH periods, and there is NPRACH an occasion, each NPRACH occasion in each NPRACH period can be used for sending a NPRACH signal.Each NPRACH signal is made of one or many duplicate NPRACH units, and each NPRACH unit can be considered as a repetition.
The running time-frequency resource configuration of NPRACH channel generally indicates by five-tuple information, can specifically include repetition number of NPRACH signal, the period, starting sub-frame offset, NPRACH channel number of sub carrier wave, originate it is one or more in subcarrier.As shown in Fig. 1 (b), when UE sends a NPRACH signal in 1 NPRACH occasion, which occupies single sub-carrier in each repetition in a manner of frequency hopping.The NPRACH signal can the subcarrier as locating for first single carrier serial number subcarrier index unique identification.
NPRACH signal has 0,1,2 three coverage enhancement grade (Coverage Enhancement Level, CE Level), can be used for fighting different signal decaying.Each CE Level corresponds to different transmission power and repetition number, as shown in table 1.
CE Level 0 CE Level 1 CE Level 2
Repetition=8 Repetition=32 Repetition=128
Table 1
Based on foregoing description, the application positions UE using NPRACH, and basic procedure is referring to Fig. 2, include:
201, MME sends the 6th message to E-SMLC.
MME sends the 6th message when there is target UE to be positioned, to E-SMLC, and request positions target UE.
202, E-SMLC sends second message to eNB.
The eNB of cell where E-SMLC to target UE sends second message, and second message is for requesting to initiate to target UE The process positioned.The application carries out UE positioning using NPRACH signal, therefore second message is specifically used for the NPRACH parameter of request target UE.
Optionally, E-SMLC can determine one or more required parameters, and determining required parameter carrying is sent to eNB in second message.Required parameter can indicate E-SMLC to the desired value of NPRACH parameter, for determining that the NPRACH parameter of target UE provides reference for eNB.
Optionally, required parameter may include one or more in following parameter:
(1) the target UE that E-SMLC is determined sends total repetition number of NPRACH signal.
(2) the target UE that E-SMLC is determined sends repetition number of NPRACH signal every time；
(3) target UE sends the NPRACH occasion number of NPRACH signal.
Required parameter can also include other parameters, in the application without limitation.
Optionally, E-SMLC can obtain the relevant parameter of target UE to determine required parameter from other network elements, can also determine required parameter according to the historical record to target UE.For example, if E-SMLC carried out positioning to target UE very recently, the historical record of target UE relevant parameter can be preserved in E-SMLC, E-SMLC determines required parameter according to the historical record of target UE relevant parameter.E-SMLC can also determine required parameter otherwise, in the application without limitation.
Optionally, second message can be information request message, or the message of other forms, in the application without limitation.
203, eNB determines the NPRACH parameter of target UE.
ENB receives the second message that E-SMLC is sent, and knows the NPRACH parameter of E-SMLC request target UE.Then eNB determines the NPRACH parameter of target UE.The NPRACH parameter of target UE is for indicating that eNB regulation goal UE sends the mode of one or many NPRACH signals, i.e., for indicating how regulation goal UE sends NPRACH signal to eNB in step 205.
Wherein, eNB regulation goal UE, which sends a NPRACH signal, can be completed the positioning of target UE.But the positioning of target UE needs at least two eNB to realize, and the signal transmission power of the UE in eNB center of housing estate is lower, signal strength when the NPRACH signal arrival adjacent area eNB for causing the UE to emit is very weak, reduces the precision of signal measurement, and then affect final positional accuracy.Therefore in the application, eNB can send multiple NPRACH signal with regulation goal UE, to improve the accuracy of target UE positioning.
Optionally, NPRACH parameter may include one or more in following parameter:
(1) eNB triggers the number K1 that target UE sends NPRACH signal.
(2) eNB sends the number K2 of NPDCCH order to target UE.
(3) eNB is the NPRACH occasion number K3 of target UE configuration.
Wherein K1, K2, K3 are integer.
Optionally, eNB can independently determine the NPRACH parameter of target UE, and the NPRACH parameter of target UE can also be determined according to the required parameter in second message.
For example, if the total repetition number in required parameter including the target UE transmission NPRACH signal that E-SMLC is determined is X1, the repetition number that eNB determines that target UE sends NPRACH signal every time is X2, then eNB can be determined in NPRACH parameter, and the number that eNB indicates that target UE sends NPRACH signal is X1/X2 It is secondary.Wherein X1, X2 are integer.
Again for example, if the NPRACH occasion number in required parameter including the target UE transmission NPRACH signal that E-SMLC is determined is Y, eNB can be determined in NPRACH parameter, and eNB triggers target UE and sends the number K1 of NPRACH signal equal to Y.Wherein Y is integer.
Required parameter is only used for determining that NPRACH parameter provides reference for eNB, is not used to limit NPRACH parameter.ENB is determining that NPRACH parameter can be with reference to required parameter or without reference to required parameter.In addition, whether the required parameter that eNB can also first judge that E-SMLC is provided is reasonable, however, it is determined that NPRACH parameter that is reasonable then determining target UE according to required parameter；If it is determined that the NPRACH parameter of unreasonable then autonomous determining target UE.
For example, if in required parameter including repetition several Z1 that the determining target UE of E-SMLC sends NPRACH signal every time, and target UE sends the NPRACH occasion number Z2 of NPRACH signal, then eNB judges whether repetition number in its time-frequency resource distribution supports numerical value Z1, if supporting, then eNB thinks that the required parameter is reasonable, eNB is determined in NPRACH parameter, the repetition number that the number K1 that eNB triggers target UE transmission NPRACH signal is equal to Z2, and sends NPRACH signal every time is Z1.Wherein Z1, Z2 are integer.
Optionally, NPRACH parameter may include parameter (4): eNB triggers the initial time that target UE sends NPRACH signal.The initial time can be the form of SFN, for indicating that target UE sends NPRACH signal since the initial time of the corresponding radio frames of the SFN.
Further, which can also include subframe numbers other than SFN, and target UE is sent the initial time of NPRACH signal specific to sub-frame accuracy；
Further, which can also include timeslot number other than SFN, subframe numbers, and target UE is sent the initial time of NPRACH signal specific to time slot precision；
Further, the initial time can also include orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing other than SFN, subframe numbers, timeslot number, target UE is sent the initial time of NPRACH signal specific to OFDM symbol precision by OFDM) symbol serial number.
Optionally, eNB can also generate target bitmap, and carry target bitmap as NPRACH parameter in first message.Target bitmap includes M bit, and the corresponding one or more continuous NPRACH occasion of each bit, M is the integer not less than 1.Target bitmap is used to indicate that eNB to dispatch the UE in this cell and sends the periodic regularity of NPRACH signal, therefore can be used to indicate that target UE sends the rule of NPRACH signal.Specifically, each bit in target bitmap has 0,1 two kinds of values, wherein value 1 indicates that target UE sends NPRACH signal on the corresponding NPRACH occasion of the bit, and value 0 indicates that target UE does not send NPRACH signal on the corresponding NPRACH occasion of the bit.
For example, eNB is that target UE is configured with 100 NPRACH occasion, and eNB generates the bitmap " 11001 " of 5 bits, wherein each bit corresponds to continuous 3 NPRACH occasion.The bitmap indicates that eNB triggering target UE cycles through NPRACH signal with the rule of " send to send not sending or not on -3 NPRACH occasion on -3 NPRACH occasion on -3 NPRACH occasion on 3 NPRACH occasion and send on -3 NPRACH occasion ", until traversing 100 NPRACH occasion.
Wherein, target bitmap only indicates that eNB dispatches the rule that the UE in this cell sends NPRACH signal, is not used to the concrete behavior of description UE.For example, on the corresponding NPRACH occasion of bit that value is 0, mesh Mark UE does not send NPRACH signal centainly.But on the corresponding NPRACH occasion of bit that value is 1, target UE can send according to the scheduling of eNB or not send NPRACH signal, in the application without limitation.
Optionally, the meaning of each bit value in target bitmap can also overturn, i.e. value 1 indicates that target UE does not send NPRACH signal on the corresponding NPRACH occasion of the bit, value 0 indicates that target UE sends NPRACH signal on the corresponding NPRACH occasion of the bit, in the application without limitation.
Optionally, bitmap can be used for the interference coordination between base station.For example: carrying out generating the bit that value is 1 in the first bitmap and the 2nd bitmap, the first bitmap and the 2nd bitmap after interference negotiation respectively that NPRACH signal is sent on corresponding NPRACH occasion for indicating between first base station and the second base station.Then between the first bitmap and the 2nd bitmap, the corresponding bit of identical NPRACH occasion is not 1 simultaneously.It can guarantee that the UE in the UE and the second base station cell in first base station cell sends the period of NPRACH signal there is no overlapping in this way, avoid the adjacent area interference occurred during positioning to UE, be capable of providing the accuracy of positioning.
Optionally, NPRACH parameter can also include one or more in the following parameter for the NPRACH signal that base station triggers target UE is sent:
The carrier frequency point information of the NB-IoT up-link carrier at place；
The running time-frequency resource configuration information of NPRACH channel, can specifically include the repetition number of each NPRACH signal of target UE transmission, the period, start frame offset, number of sub carrier wave, originate it is one or more in subcarrier；
Base station is the subcarrier index of target UE configuration, and the subcarrier index is for indicating that target UE sends the starting subcarrier of NPRACH signal in 1 NPRACH occasion.
NPRACH parameter can also include other parameters, in the application without limitation.
204, eNB sends first message to E-SMLC.
ENB is sent to E-SMLC after the NPRACH parameter of target UE has been determined, by the NPRACH parameter carrying of target UE in first message.
Optionally, first message can be information response message, or the message of other forms, in the application without limitation.
205, eNB triggers target UE and sends NPRACH signal.
For eNB after the NPRACH parameter of target UE has been determined, triggering target UE sends NPRACH signal.Wherein, the mode that eNB regulation goal UE sends NPRACH signal should be consistent with NPRACH parameter.
For example, if number K1, eNB that NPRACH parameter includes eNB triggering target UE transmission NPRACH signal should trigger target UE and send K1 NPRACH signal.Specific triggering mode has very much, such as: eNB sends NPDCCH order to target UE, target UE sends a NPRACH signal after receiving NPDCCH order, and eNB replys the confirmation message of the NPRACH signal to target UE, then sends NPDCCH order to target UE again.Target UE is triggered by K1 NPDCCH order altogether and sends K1 NPRACH signal.In another example, eNB sends NPDCCH order to target UE, target UE sends a NPRACH signal after receiving NPDCCH order, eNB does not reply the confirmation message of the NPRACH signal to target UE, so that target UE sends NPRACH signal again, until eNB replys the confirmation message of the NPRACH signal to target UE again after target UE has sent K1NPRACH signal.
Again for example, if NPRACH parameter includes the number K2 that eNB sends NPDCCH order to target UE, Then eNB sends K2 NPDCCH order, each NPDCCH order to target UE and is used to triggering target UE transmission NPRACH signal.
Again for example, if NPRACH parameter includes the NPRACH occasion number K3 that eNB is target UE configuration, then eNB is that target UE configures K3 NPRACH occasion, and target UE is allowed to send NPRACH signal on one or more NPRACH occasion in the K3 NPRACH occasion.
Again for example, if NPRACH occasion number K3, target UE that number K1 and eNB that NPRACH parameter includes eNB triggering target UE transmission NPRACH signal are target UE configuration can send NPRACH signal on K1 NPRACH occasion in the K3 NPRACH occasion.Wherein K1 is not more than K3.
It may be other methods that eNB regulation goal UE in a manner of meeting NPRACH parameter, which sends NPRACH signal, in the application without limitation.
The sequencing between step 204 and 205 is not limited in the application, step 205 can also be located at before step 204.
206, E-SMLC determines target LMU.
E-SMLC is selected multiple for measuring the target LMU of the position of target UE in the LMU of NB-IoT system.In order to realize the positioning of target UE, the number at least two of target LMU.The target LMU that E-SMLC also can choose three or three or more positions target UE, to promote the accuracy of positioning.
207, E-SMLC sends third message to target LMU；
After E-SMLC receives first message, the NPRACH parameter of the target UE carried in first message is obtained.Then E-SMLC sends third message to determining multiple target LMU, the NPRACH parameter of target UE is carried in the third message, 4th information is used to indicate each target LMU according to the NPRACH parameter of target UE, at the time of the NPRACH signal that measurement target UE is sent reaches the LMU.After target LMU receives third message, it can know that target UE sends the mode of NPRACH signal, and then the NPRACH signal of target UE transmission can be received according to NPRACH parameter according to the NPRACH parameter of target UE.
For example, if NPRACH parameter includes the number K1 that eNB triggering target UE sends NPRACH signal, target LMU, which can be known altogether, can receive K1 NPRACH signal.
Again for example, if NPRACH parameter includes the NPRACH occasion number K3 that eNB triggering target UE sends the number K1 and eNB of NPRACH signal as target UE configuration, then target LMU can be informed on the K3 NPRACH occasion receive target UE NPRACH signal, can receive altogether in K1 NPRACH signal.
Again for example, if NPRACH parameter includes the initial time that target UE sends NPRACH signal, target LMU can be informed in the initial time and start to receive target UE transmission NPRACH signal.
Again for example, if NPRACH parameter includes target bitmap, the bit that wherein value is 1 indicates that target UE sends NPRACH signal on the corresponding NPRACH occasion of the bit, then target LMU, which can be informed on the corresponding NPRACH occasion of bit that value is 1 in target bitmap, receives target UE transmission NPRACH signal, does not receive target UE on the corresponding NPRACH occasion of bit that value is 0 in target bitmap and sends NPRACH signal.
Each target LMU receives target UE and sends one or more NPRACH signal according to the NPRACH parameter in third message, and at the time of measure one or more NPRACH signal and reach target LMU, obtains measuring and tie Fruit.
208, target LMU sends the 4th message to E-SMLC.
Respective measurement result is carried and is sent in the 4th message to E-SMLC by multiple target LMU.
209, E-SMLC positions target UE.
E-SMLC receives the 4th message that multiple target LMU is sent, and obtains the measurement result of each target LMU, at the time of the one or more NPRACH signals for knowing that target UE is issued reach each target LMU.E-SMLC calculates the position of target UE according to the measurement result.
In the present embodiment, eNB determines the NPRACH parameter of target UE and is sent to E-SMLC, the NPRACH parameter of target UE is transmitted to multiple target LMU by E-SMLC, multiple target LMU are enabled to receive the NPRACH signal of target UE transmitting according to the NPRACH parameter of target UE, E-SMLC in this way can calculate the position of target UE according to the time difference that NPRACH signal reaches multiple target LMU, realize the positioning of target UE.
In order to guarantee the precision of positioning, the power that UE emits NPRACH signal cannot be too low.Therefore, the lower UE of maximum transmission power is not suitable for being positioned.For this purpose, the application also refines terminal device localization method shown in Fig. 2, it is ensured that UE not lower to maximum transmission power is positioned, and please refers to Fig. 3.Step 301 occurs after step 202 in the embodiment shown in Figure 2, E-SMLC send second message to eNB in Fig. 3, specific:
301, eNB obtains the power information of target UE；
ENB obtains the power information of target UE, and judges whether the power information of target UE meets the first prerequisite.
Optionally, the power information of target UE can be indicated by many kinds of parameters, and different parameters corresponds to the first different prerequisites.For example, the peak signal that the power information of target UE can be target UE sends power, and the first prerequisite can be first threshold.If the peak signal of target UE, which sends power, is less than first threshold, then it is assumed that the power information of target UE does not meet the first prerequisite；If the peak signal of target UE, which sends power, is not less than first threshold, then it is assumed that the power information of target UE meets the first prerequisite.
Again for example, the power information of target UE can be the peak signal transmission power level of target UE, and it includes multiple preset power grades in the preset power class set that the first prerequisite, which can be preset power class set,.If the peak signal transmission power level of target UE belongs to the preset power class set, then it is assumed that the power information of target UE meets the first prerequisite；If the peak signal of target UE sends power and is not belonging to the preset power class set, then it is assumed that the power information of target UE does not meet the first prerequisite.
If the power information of target UE does not meet the first prerequisite, eNB executes step 302.

302, eNB sends the 5th message to E-SMLC.
If the power information of target UE does not meet the first prerequisite, eNB sends the 5th message to E-SMLC, and the 5th message is used to indicate request of the refusal E-SMLC to the NPRACH parameter of target UE.
After eNB sends the 5th message to E-SMLC, positioning flow is terminated, and each network element does not execute subsequent step 203~209.
Optionally, the first cause field can also be carried in the 5th message, request of first cause field for indicating " Reason For Denial is related to power ", i.e., because of power reason refusal E-SMLC to the NPRACH parameter of target UE.

In embodiment shown in Fig. 3, it is determined whether executed to the target UE operation positioned by eNB.In practical applications, it is determined whether the operation positioned to target UE can also be executed by E-SMLC, please refer to Fig. 4.It is specific:
201, MME sends the 6th message to E-SMLC.
This step is identical as the step 201 in embodiment shown in Fig. 2, i.e. MME sends the 6th message when there is target UE to be positioned, to E-SMLC, and request positions target UE.It further include the power information of target UE but in the present embodiment, in the 6th message.
E-SMLC obtains the power information of target UE in the 6th message, and judges whether the power information of target UE meets the second prerequisite.
Optionally, the power information of target UE can be indicated by many kinds of parameters, and different parameters corresponds to the second different prerequisites.For example, the peak signal that the power information of target UE can be target UE sends power, and the second prerequisite can be second threshold.If the peak signal of target UE, which sends power, is less than second threshold, then it is assumed that the power information of target UE does not meet the second prerequisite；If the peak signal of target UE, which sends power, is not less than second threshold, then it is assumed that the power information of target UE meets the second prerequisite.
Again for example, the power information of target UE can be the peak signal transmission power level of target UE, and it includes multiple preset power grades in the preset power class set that the second prerequisite, which can be preset power class set,.If the peak signal transmission power level of target UE belongs to the preset power class set, then it is assumed that the power information of target UE meets the second prerequisite；If the peak signal of target UE sends power and is not belonging to the preset power class set, then it is assumed that the power information of target UE does not meet the second prerequisite.
If the power information of target UE does not meet the second prerequisite, E-SMLC executes step 401.
Optionally, if the power information of target UE meets the second prerequisite, E-SMLC receives the request that MME positions target UE in the 6th message.Specific accepting method can execute step 202 for E-SMLC, and each network element cooperation to the NPRACH parameter of eNB request target UE, and in NB-IoT executes the step 202~209 complete positioning flow.
401, E-SMLC sends the 7th message to MME.
If the power information of target UE does not meet the second prerequisite, E-SMLC sends the 7th message to MME, and the 7th message is used to indicate the request that refusal MME positions target UE.
After E-SMLC sends the 7th message to MME, positioning flow is terminated, and each network element does not execute subsequent step 203~209.
Optionally, the second cause field can also be carried in the 7th message, second cause field is for indicating " Reason For Denial is related to power ", i.e., because power reason refuses the request that MME positions target UE.
In the present embodiment, whether E-SMLC meets the second prerequisite according to the power information of target UE, to determine whether to position target UE.It can ensure only to position the UE that maximum transmission power is met the requirements in this way, guarantee UE Positioning accuracy.
