Description

A kind of location area updating method of subscriber equipment and device

Technical field

The present invention relates to communication technical field, particularly relate to a kind of location area updating method of subscriber equipment, and, a kind of location area updating device of subscriber equipment.

Background technology

User equipment (UE) may leave the current area coverage and enters new residential quarter in the standby process, and user equipment (UE) will break away from original residential quarter and determine resident relation with new residential quarter this moment.Under certain state, user equipment (UE) can utilize cell re-selection mechanism to finish selection to new residential quarter.Cell reselection is the prerequisite function of mobile communication system, it is RRM(Radio Resource Management, RRM) important component part, UE(User Equipment, subscriber equipment) cell reselection under idle pulley is for the UE persistent district that upgrades in time, make UE reside in desirable residential quarter, thereby guaranteed receiving system message and paging information that UE can be correct, and guarantee the access success rate of UE.

Enter new TD LAC(location area code, Location Area Code with reference to user equipment (UE) shown in Figure 1) the cell reselection process flow chart, the process of cell reselection is as follows:

(1) UE is under idle condition, with cycle DRX(Discontinuous Reception, discontinuous reception) the P-CCPCH(Primary Common Control Physical Channel of measurement current service cell, Primary Common Control Physical Channel) received power on the channel (P-CCPCH RSCP), and according to measurement result calculating path loss canonical parameter Srx.If the Srx of current service cell＜0 or current service cell are hindered, Srx＜the Sintrasearch(common frequency measurement triggers thresholding) or Srx＜Sintersearch(different-frequency measure trigger thresholding) time, UE will trigger the measurement with frequency or alien frequencies neighbor cell.

(2) user equipment (UE) is according to the measurement result of above-mentioned measurement and calculation plot selective reception level value Srxlev and priority parameters R in the system information, and R is larger, and priority is higher.If in the Treselection(cell reselection triggered time) adjacent cell is higher than the priority of current area in the cycle, and then start physical-layer cell and heavily search process, re-selecting cell.

(3) process is heavily searched in the residential quarter: user equipment (UE) carries out synchronously with read system message with new residential quarter.

System message can be divided into Master Information Block (MIB) and system information block (SIB).MIB can comprise the sign of PLMN, the SIB type of message in the system broadcast information, and corresponding schedule information.In MIB, can comprise Scheduling Block (SB), comprise parameter and the schedule information of other block of informations (SIB) among the SB.More when system information block, first Scheduling Block SB1 occurred when MIB can't provide the schedule information of whole SIB; If MIB and SB1 are added together the schedule information that still can't provide whole SIB, second Scheduling Block SB2 occurs.Generally speaking, relating to block of information comprises: MIB, SB1﹠amp; SB2, SIB1, SIB2, SIB3, SIB5, SIB7, SIB11, SIB18.It is constructed as follows:

(4) if do not find MIB on the system message, perhaps do not have the information of SIB1, SIB3, SIB5, SIB7, think that then this residential quarter is under an embargo, discontented lumping weight selects the requirement of residential quarter, does not then select this residential quarter, reselects time priority residential quarter and carries out the residential quarter and heavily search.

(5) from SIB1, obtain present position-region information, compare with user equipment (UE) self-position district information, if inconsistent then submit NAS layer (Non-Access Stratum) and carry out the location area updating process.

Yet above-mentioned cell reselection process has the following disadvantages:

1) in the read apparatus message process, because user equipment (UE) can't be accepted the total time that total duration of beep-page message is above-mentioned steps (4) and (5) two steps of step, therefore user equipment (UE) to network can't paging receiving time long, cause access failure probability height;

2) existing flow process causes the user equipment (UE) position longer update time, is unfavorable for the network exact paging, the waste Internet resources.

Therefore, those skilled in the art's technical problem to be solved provides a kind of location area updating mechanism of subscriber equipment, in order to reduce user equipment (UE) gravity treatment time delay, elevator system call completing rate.

Embodiment

For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.

The core idea of the embodiment of the invention is, when realizing that UE carries out the process of TD net interior span LAC gravity treatment, terminal has read SIB1, SIB3, SIB5, during the system messages such as SIB7, namely submit to the NAS layer, finish the Non-Access Stratum process, in time carry out location area updating, after finishing the Non-Access Stratum process, UE selects to remain reading of SIB message according to current state.Thereby reduced the time that other system message that UE reads with the position is upgraded and paging accepts to have nothing to do takies, also be conducive to the accurate paging of network side, reduced the probability of network while issuing page message under a plurality of LAC.

With reference to Fig. 2, show the flow chart of steps of the location area updating method embodiment 1 of a kind of subscriber equipment of the present invention, specifically may further comprise the steps:

Step 101: obtain the candidate cell tabulation;

In specific implementation, UE at first will seek and select network after start, then registers with the position by certain residential quarter in the network and upgrades, thereby reside in this residential quarter.Behind the selected resident residential quarter, UE seeks a better residential quarter regularly according to the cell reselection criterion, and this is called " cell reselection ", and the purpose of cell reselection is to select the residential quarter that more " is fit to " resident to guarantee service quality according to current measurement result.UE can carry out cell reselection at idle and RRC connection mode.Cell reselection is a kind of terminal behavior, the normally user migration initiatively initiated of terminal.

In a preferred embodiment of the present invention, described step 101 can comprise following substep:

Substep S11: measure the Serving cell of user equipment (UE), obtain the measurement result of described Serving cell, wherein said Serving cell is the current resident residential quarter of user equipment (UE);

Under idle condition, base station side (comprising base station eNB, radio network controller (RNC), base station controller BSC) instructs UE that Serving cell is measured, the P-CCPCH(Primary Common Control Physical Channel of this residential quarter of UE periodic measurement, Primary Common Control Physical Channel) received power on the channel (P-CCPCH RSCP), each DRX(Discontinuous Reception, discontinuous reception) cycle measures once at least.

Particularly, P-CCPCH is used for carrying from the data of transmission channel BCH, and the broadcasting of the system message under the replace mode of full residential quarter is provided, and the data on this channel of will searching for and decode after UE powers on are to obtain cell system message.P-CCPCH RSCP on the P-CCPCH channel has reflected the signal strength signal intensity of current area.

Substep S12: path loss criterion parameter and the priority parameters of the measurement result calculation services residential quarter of the described Serving cell of foundation;

Particularly, terminal is according to the path loss criterion parameter Srx of the measurement result Qrxlevmeas calculation services residential quarter of described Serving cell, if in N continuous serv the DRX cycle, the Srx of Serving cell＜=0, perhaps current area is under an embargo, and (the forbidden situation of current area is: do not find MIB on the system message, the message that does not perhaps have SIB1, SIB3, SIB5, SIB7), UE will start the surveying work to all adjacent cells, measure the P-CCPCH RSCP of described neighbor cell.

In addition, if the Srx of Serving cell〉0 but satisfy following trigger condition, UE also can initiate the surveying work of adjacent cell, does not adopt the Measurement principle of floored community (HCS):

(1) if Srx〉Sintrasearch(common frequency measurement triggering thresholding), user equipment (UE) does not need to carry out the measurement of co-frequency cell;

If Srx＜=Sintrasearch, user equipment (UE) need to carry out the measurement of co-frequency cell;

If do not send Sintrasearch in the system information of Serving cell, user equipment (UE) carries out the measurement of co-frequency cell;

(2) if Srx〉Sintersearch(different-frequency measure triggering thresholding), user equipment (UE) does not need to carry out the measurement of alien-frequency district;

If Srx＜=Sintersearch, user equipment (UE) need to carry out the measurement of alien-frequency district;

If do not send Sintrasearch in the system information of Serving cell, user equipment (UE) carries out the measurement of alien-frequency district.

Wherein, Sintersearch is for starting the threshold parameter of different-frequency measure; Sintrasearch is for starting the threshold parameter of common frequency measurement; These two parameters read from the system broadcast message of Serving cell, need do the conversion of taking advantage of 2 arithmetic that add l to change after the system broadcast message of Serving cell is read.

In specific implementation, Srx can adopt following formula to obtain:

S _rx=Qrxlevmeas-Qrxlevmin-Pcom；

Pcom=MAX(UE_TXMAX_RACH-P_MAX,0)；

Wherein,

Qrxlevmeas is the received power (P-CCPCH RSCP) that UE measures at the P-CCPCH channel;

Qrxlevmin is the minimum access received power (dBm) that the residential quarter requires, and this parameter is broadcasted by system message;

UE_TXMAX_RACH is the maximum transmission power that UE allows at Random Access Channel RACH, by system broadcast message notice UE, is the maximum transmission power of UE on the RACH channel that system allows;

P_MAX is the radio-frequency emission power of UE maximum, is the actual maximum power that can launch of UE;

In practice, consider that the restriction of transmitting power of UE reality is for the impact of on-position, when weighing the Srx parameter, introduce parameter Pcom, as UE_TXMAX_RACH〉during P_MAX, the actual transmission ability that is UE does not reach the maximum transmission power that system allows, this moment Pcom=UE_TXMAX_RACH-P_MAX 0, that is to say the actual transmission ability of UE may restricting user equipment the on-position of UE, need to consider this impact this moment.If but Pcom equals 0, that is to say that the actual transmission ability of UE is enough to satisfy the access requirement, need not to consider the impact of UE actual emission power this moment.

For example: in the supposing the system broadcast Qrxlevmin=-51dBm is set; Sintrasearch=1dB; UE_TXMAX_RACH=30dBm; P_MAX=24dBm: user equipment (UE) received power Qrxlevmeas=-83dBm; Offset Pcom=max(30-24 then, 0)=6dB.Therefore, Srx=Qrxlevmeas-Qrxlevmin-Pcom=-83-(-51*2+1)-6=12dB＞l*2+1; That is, if user equipment (UE) received power Qrxlevmeans value be lower than-during 92dBm, Srx＜Sintrasearch will start all co-frequency neighbor cells and measure

As a kind of preferred exemplary of present embodiment, the priority parameters of Serving cell can be used R _sExpression, can adopt following account form:

R _s=Q _means,s+Qhyst _s；

Wherein,

Qmeans, s: be the measurement result of Serving cell;

Qhyst: be hysteresis, issued by system message.

Substep S13: the path loss criterion parameter of the described current persistent district of foundation triggers the measurement to the neighbor cell of or alien frequencies frequently same with current persistent district, obtains the measurement result of described neighbor cell;

In the specific implementation, to the measurement of neighbor cell, be the received power (P-CCPCH RSCP) of measuring on the P-CCPCH channel of described neighbor cell.。

Base station periodic broadcast neighboring broadcast messages comprises frequency, physical code and the modulation intelligence of the residential quarter adjacent with Serving cell in this message; UE obtains neighbor cell list when reading the system message of current service cell.

Substep S14: path loss criterion parameter and the priority parameters of calculating described neighbor cell according to the measurement result of described neighbor cell;

In specific implementation, the computational methods of the path loss criterion parameter of neighbor cell are with reference to the computational methods of the path loss criterion parameter of above-mentioned Serving cell, and the embodiment of the invention is not described in detail in this.

The priority parameters of described neighbor cell can be used R _nExpression, its computational methods are as follows:

R _n=Q _means,n-Qoffset _s,n

Wherein,

Qmeans, n: be the measurement result of neighbor cell;

Qoffset: the gravity treatment side-play amount of neighbor cell, so that this residential quarter is arrived in the easier or more difficult gravity treatment of UE, this parameter is obtained by system message by adjusting this parameter.

Substep S15: in described Serving cell and neighbor cell, selecting paths loss canonical parameter greater than the residential quarter of predetermined threshold value as candidate cell, all candidate cells form the candidate cell tabulation, in described candidate cell tabulation, described candidate cell sorts according to the priority parameters of himself.

In specific implementation, behind the path loss criterion parameter Srx that calculates the residential quarter adjacent with the user equipment (UE) Serving cell, with all Srx〉0 neighbor cell is as candidate cell, all candidate cells form the candidate cell tabulation, in described candidate cell tabulation, all candidate cells are ranked, according to priority R parameter (R _n) size carry out priority arrangement, the R parameter is larger, priority is higher.In fact, at the Srx of Serving cell〉0 o'clock, can if the priority parameters of Serving cell is arranged in the front of candidate cell tabulation, then not need to carry out cell reselection with Serving cell as candidate cell yet, otherwise, the process of triggering cell gravity treatment.

Step 102: read according to the order of sequence the first system message of the candidate cell in the tabulation of described candidate cell, determine the re-selecting cell of user equipment (UE) according to described the first system message, described the first system message is the essential system message of described candidate cell;

Particularly, UE attempts from high to low one by one according to priority orders in the candidate cell tabulation, reads the first system message of each candidate cell, until determine the resident re-selecting cell of user equipment (UE).

Essential system message in all system messages that described the first system message is described candidate cell, as a kind of preferred exemplary of the embodiment of the invention, described the first system message can be the message of SIB1-SIB7.3GPP(3rd Generation Partnership Project, third generation partner program) RRC(Radio Resource Control, radio resource control) stipulates in the agreement, SIB1 ~ SIB7 is essential system message, if do not read complete these message, will cause the UE can't be resident in this residential quarter.

In a preferred embodiment of the present invention, described step 102 can comprise following substep:

Substep S21: read the first system message of the highest candidate cell of candidate cell tabulation medium priority parameter, described the first system message comprises the 3rd system information block;

In background technology, user equipment (UE) need to read all system message rears can carry out suitable cell (satisfy UE resident/residential quarter of reselection conditions, UE can obtain the residential quarter of normal service) select the process of (assessment), whole process time is consuming time longer.And in the embodiment of the invention, after having read the first system message SIB1-SIB7, just can carry out the suitable cell assessment, thereby shorten the time of read system message, reduce user equipment (UE) and when carrying out the suitable cell assessment, read the time that other system without interaction message take.

With reference to read system message schematic diagram shown in Figure 3, can find out, beginning to be about 520ms to the SIB7 duration by the user equipment (UE) read system message, read the 720ms of being about consuming time after all system messages, after the method for the use embodiment of the invention reads first the first system message, with respect to the 720ms of former flow process, can shorten the invisible time value 200ms of user equipment (UE), shortened the time of 200/720=27.8%.And along with increasing of residential quarter neighboring BS information, the time of reading of SIB11, SIB18 can be longer, and the time of utilizing the method for the embodiment of the invention to save is also just more.

Substep S22: the first system message according to described candidate cell judges whether described candidate cell meets default cell reselection condition, if, then described candidate cell is the re-selecting cell of user equipment (UE), if not, then return candidate cell tabulation and read the first system message of time high candidate cell of priority parameters, by that analogy, wherein

Described default cell reselection condition is:

In specific implementation, the process of substep S22 is the process of suitable cell assessment, in the process of assessment, UE attempts from high to low one by one according to priority orders in the candidate cell tabulation, at first select the highest candidate cell of candidate cell tabulation medium priority, read the first system message of described candidate cell, the first system message according to described candidate cell judges whether described candidate cell meets default cell reselection condition, particularly, described default cell reselection condition is: in the time interval Treselection(cell reselection triggered time) in, the priority of candidate cell is higher than the priority parameters (R of current service cell _nR _s), and the SIB3 value of candidate cell is the non-residential quarter of forbidding accessing.The residential quarter that meets default cell reselection condition is re-selecting cell.

If described candidate cell does not meet described cell reselection condition, then described candidate cell is not re-selecting cell, user equipment (UE) is selected the residential quarter of time priority to carry out the residential quarter in the tabulation of described candidate cell heavily to search, read the first system message of next candidate cell again.

On the other hand, if described candidate cell satisfies following condition, described candidate cell is not re-selecting cell yet: if do not find MIB on the system message, perhaps there is not SIB1, SIB3, SIB5, the information of SIB7 thinks that then this residential quarter is under an embargo, and discontented lumping weight selects the requirement of residential quarter.

Step 103: the location area information of obtaining described re-selecting cell;

In a preferred embodiment of the present invention, described the first system message comprises the first system block of information message, and described step 103 can comprise following substep:

Substep S31: the location area information that from described the first system block of information message, obtains described re-selecting cell.

Particularly, user equipment (UE) obtains the location area information of current service cell from the SIB1 of the first system message after reading the first system message of re-selecting cell.Wherein, the lane place refers to the LA(Location Area in core net CN), lane place (LA) is the set of one group of residential quarter (Cell) in the mobile communication system, is an important component part of UE mobile management.The effect in setting position district is to make mobile switch or mobile switching centre (MSC) can in time know the position of UE, and when calling out UE, mobile switching centre just all residential quarters in the lane place of this UE is searched for, and can find quickly and accurately UE.Lane place (LA) is stored in the Subscriber Identity Module (being SIM card) of user mobile phone, when UE roams in network, when inconsistent such as the lane place in the discovery SIM card and mobile network's lane place, just sends the message that the position is upgraded to network.

Step 104: the location area information of obtaining user equipment (UE);

Step 105: whether the location area information of judging described user equipment (UE) is consistent with the location area information of described re-selecting cell; If inconsistent, then execution in step 106; If consistent, then execution in step 107;

Step 106: the location area information of upgrading described user equipment (UE);

In specific implementation, when UE selects a certain residential quarter as own residential quarter that will be resident, it can compare to judge whether the lane place at this place, residential quarter changes by the location area information with user equipment (UE), if the location area information of the location area information of candidate cell and user equipment (UE) is inconsistent, illustrate that then UE wants resident residential quarter to belong to a new lane place, need to submit the NAS layer and carry out the location area updating process.

In a preferred embodiment of the present invention, described step 106 can comprise following substep:

Substep S41: the location area information of upgrading described user equipment (UE) is the location area information of described re-selecting cell.

When the location area information of upgrading described user equipment (UE) is the location area information of described re-selecting cell, then the location area information of user equipment (UE) is consistent with the location area information of described re-selecting cell, continuation execution in step 107;

In specific implementation, the process that the position is upgraded also can be called the position registration, if UE registers successfully in a certain candidate cell, then the location area information of user equipment (UE) is consistent with the location area information of described re-selecting cell, determines that described re-selecting cell is the normal resident residential quarter of user equipment (UE); If register unsuccessfully, improper this residential quarter that resides in of UE then, at this moment UE only can carry out restricted service, for example urgent call.

Step 107: determine that described re-selecting cell is the normal resident residential quarter of user equipment (UE).
