Description
Technical field
The present invention relates to mobile communication technology, relate in particular to a kind of collocation method, system and device of tracking area tabulation.
Background technology
LTE (Long Term Evolution) is the mobile wireless network of future generation of 3GPP (3rd Generation Partnership Project, third generation partner program), compares existing 3G network, has more high bandwidth, more hangs down characteristics such as time delay.
The LTE network is the network of an all-IP; In wireless side RNC (Radio Network Controller radio network controller) and NodeB (base station) are synthesized a network element eNodeB (evolution base station); The location management of whole network also adds the management in route district from original lane place, be evolved into the management of TA (TrackingArea, tracking area); Each tracking area is discerned with unique sign TAI (Tracking Area Identifier, tracking area identification).Owing to the One's name is legion of tracking area in the LTE network, UE can produce a large amount of tracing section updating signalings in the frequent process that moves under idle condition, and these renewal signalings can cause bigger load pressure to core net, the resource that also can waste network in a large number simultaneously.
In this case, in the 3GPP standard mobile management of UE, defined a completely new concept specially; TA List (TrackingArea List, tracking area tabulation), network side is that UE distributes a TAList; As shown in Figure 1, comprise a plurality of TA in the tracking area tabulation, and comprised a plurality of sub-districts under each TA; When UE moves under idle condition; As long as the TA of process all be present among the TA List that is distributed, UE just need not frequently to initiate position updating request so, has reached the purpose of saving Internet resources.Have only as UE and detect it and got into a tracking area TA who has not yet registered, and this TA is not present among the TA List that is distributed before the network, UE just can initiate TAU (Tracking Area Update, tracing section updating).
The MME of network side (Mobility Management Entity; Mobile management entity) is the configuration of TA List and issues entity; When UE carries out TAU or attachment flow; MME can carry out the confirming of the TA List of UE according to UE is registered in TAI (in TAU Request message, being provided by UE) among the MME, current UE place TA at a preceding TAU or when adhering to TAI (eNodeB by current provides) and the information in the UE subscription data, when confirming, need consider direction and the range size of TA List etc.And can comprise the several or a plurality of TA among the original T A List among the new TA List, to avoid ping-pong.At last, MME can be handed down to UE with new TA List in Attach Accept, TAU Accept or GUTI Relocation Command message.
Need to prove; When UE is under the idle condition when in the TA that TA List is comprised, moving; Among the MME of network side to the location of UE still for before the TA that belongs to when initiating TAU of UE, when network side is initiated the paging to UE, can carry out in all TA in the TA of distributing to UE List.
Though, designed the notion of TA List, can reduce UE moves the numerous TAU that carries out of time-frequency under idle condition number of times; TA List is big more; The number of times of TAU is just few more, but owing to when network during at paging UE, understand and in all TA that whole TA List is covered, carry out paging; If TA List coverage is bigger, also consumption network Limited resources greatly.
It is thus clear that the size of the size of paging domain and TA List is a pair of contradiction.TA List crosses conference makes paging zone excessive, can increase the unnecessary resource overhead of network when calling out UE; And conversely, TA List is too small, diminishes though call out the scope of UE; But can cause UE frequent position of carrying out between different TA to be upgraded, not only can greatly increase the load of network, reduce the performance of network; Simultaneously also can consume the UE own resources, like the battery flying power etc.
Inventor of the present invention finds; Since MME be according to UE provide before the subscription data of TAI and some UE of the current UE position that provides of TAU or the TAI that adheres to when registration and eNodeB carry out new TA List and distribute, and such distribution method is not very effective.On the one hand; Only through two TAI, MME can not judge the direction that UE moves very effectively, accurately, and the direction that such TA List that distributes possibly move with UE on direction is inconsistent; Thereby unnecessary radio resource consumption when causing paging has also increased the frequency of TAU; On the other hand, MME also can't be known the movement rate that UE is current, and can't being determined to the end, in TAList, to distribute what TA to be only the most effective, thereby cause the TA List that is distributed excessive or too small.

Embodiment
The embodiment of the invention provides collocation method, system and the device of a kind of tracking area tabulation, when distributing tracking area to tabulate for UE, and the position recorded information that gets access to UE simultaneously and write down; Confirm factors such as direction that UE moves and movement rate according to this information; Thereby according to direction and the movement rate that UE moves, can reasonably distribute the tracking area tabulation, both control the coverage of tracking area tabulation; Reduce the frequency of TAU again, and then improved the performance of network.
The collocation method of the tracking area tabulation that the embodiment of the invention provides carries out balance between paging zone size and TAList (tracking area tabulation) size, through the optimization to TA List, both satisfied the validity of paging, reaches again and reduces unnecessary TAU signaling consumption.Because the situation of movement of UE has only UE self the clearest; So the embodiment of the invention is carried out record through UE to self situation of movement; And this is recorded in reports network MME when initiating TAU, make MME grasp the motion conditions of UE, MME is on the basis of having understood the UE motion conditions; Through analyzing and calculating, design suitable TA List again.
Because being the up-to-date situation of movement according to UE, the TAList that MME generates designs; And the situation that each UE moves generally is different, and according to the different motion situation of different UEs, MME can design different TA List; Like this; Except can the balancing paging district and TA List size between contradiction, can also prevent that sending a large amount of UE in same place that same TA List causes to UE initiates TAU to network simultaneously, cause network load moment to increase.
As shown in Figure 2, the collocation method of the tracking area tabulation that the embodiment of the invention provides comprises:
The position recorded information that step S201, mobile terminal receive send, in the recorded information of position journal the eNodeB information of portable terminal process, and the time span of timer record;
Step S202, analyze the position recorded information of portable terminal, confirm the direction and the speed of motion of mobile terminals;
Step S203, according to the direction and the speed of motion of mobile terminals, the tracking area tabulation of configuration portable terminal, and send to portable terminal.
In step S201; Portable terminal can send to MME in the lump with position recorded information and tracing section updating request; Can also further the position recorded information be carried in the tracing section updating request and send; A kind of mode of carrying is: the Last VisitedRegistered TAI field in expansion TAU Request (tracing section updating request) message, writing position recorded information in the field after expansion.
Because UE is under idle condition, every through a TA, himself the eNodeB ID and the TAI that can receive all that eNodeB broadcasts; And UE can be with these a few eNodeB ID and TAI one by one after the correspondence, in the sequential storage put information on the throne, and the situation of movement that represents UE that the position recorded information just can be complete like this; The position recorded information can be the eNodeB ID/TAI tabulation of reflection UE situation of movement; Also eNodeB information can be only write down,, the data volume that sends to MME can be further reduced like this as long as can eNodeB of unique identification; MME is after receiving the position recorded information; If only write down eNodeB information in the recorded information of position, MME can determine the tracking area at this eNodeB place according to the division of tracking area.
Be the further size of control TAU Request message, prevent excessively after the TAU Request extension of message to take too much system resource, can maximum length be set for extended field; UE constantly writes eNodeB ID/TAI to the position recorded information in proper order in moving process; When the position recorded information surpasses this length,, can be with top eNodeB ID/TAI record deletion; Can prevent that like this TAU Request message is excessive, also can guarantee the state-of-the-art record that is recorded as in the recorded information of position.
According to defined among the 3GPP24.301; TAU Request message size is at least 80 bytes; And cover down in homogeneous networks, sign TA is two bytes of need only, so can think the expansion that Last VisitedRegistered TAI field is carried out; Can significantly not increase the size of TAU Request message, therefore can't bring very big influence to network side because the message capacity becomes big.
Because UE just can receive the broadcast message with its sign that location eNodeB sends based on existing hardware when mobile; So need in UE, not generate the position recorded information by extra increase hardware; Only need eNodeB ID/TAI information Recognition in the broadcast message and storage be got final product, can significantly not increase the hardware complexity of UE.
In step S202; MME analyzes the position recorded information of portable terminal; According to eNodeB ID that writes down in the recorded information of position and TAI number; Can roughly determine the distance of motion of mobile terminals,, determine the speed of motion of mobile terminals again according to the time span that writes down in the recorded information of position.
MME can estimate the relative position of eNodeB and TA according to the eNodeB and the TA information of storage, determines the direction of motion of mobile terminals.
For further confirming the direction and the speed of motion of mobile terminals more accurately; Can store the geographical location information of eNodeB and tracking area among the MME; This geographical location information can be the GPS locating information; Can manual work When building their networks import MME or let eNodeB offer MME through the mode that reports automatically, MME can consult or calculate the actual distance size and true relative position between each eNodeB or the TA in this part geographical location information table, so just can be according to the eNodeB that stores and the geographical location information of tracking area; And the position recorded information of portable terminal; Come more accurate direction and the distance of confirming that portable terminal moves, the time span that writes down in distance that moves according to portable terminal again and the position recorded information is confirmed the rate travel of portable terminal.
MME confirms moving direction and the rate travel of UE according to the position recorded information.The moving direction of UE can help MME to confirm the bearing of trend of tracking area among the distribution T AList, and MME can be assigned among the TAList by the TA that these are regional after being informed in the zone of the most possible entering of UE in the future; The rate travel of UE can help MME to confirm the coverage of tracking area among the TA List, lets MME know the situation of the speed that nearest a period of time of UE moves, thereby determines will distribute what TA at TAList on earth.For the fast situation of speed, the coverage of tracking area can be distributed more greatly among the TA List; For the slow situation of speed, the coverage of tracking area can be distributed smallerly among the TAList.So, not only can solve the generation of the unnecessary frequent TAU signaling message of UE, can also on most possible direction and in the optimal scope, carry out paging UE.
Further, because the rate travel of portable terminal may change, for example the user is from transfer to by bus on foot; So in order to make MME can calculate the up-to-date rate travel situation of portable terminal, can be so that the timer of portable terminal carries out the periodicity timing, and in the put information on the throne the record portable terminal the change number of times of eNodeB of process; When timer reaches predefined time cycle in the time span of record; Restart timing, when picking up counting at every turn, write down again portable terminal the change number of times of eNodeB of process; If detecting, UE got into a new TA; And need carry out TAU, then stop timing at once, and keep the number of times information that current eNodeB and TA change and the timing time of timer.Like this MME according to write down in the recorded information of position change number of times and the eNodeB information of eNodeB of process determine in the time span of timer record; The displacement of portable terminal; Calculate the rate travel of portable terminal again; Because timer is the meeting reclocking when reaching timing cycle, so this translational speed is the most current speed of portable terminal.
When confirming the direction that portable terminal moves; Can confirm simply that the direction that portable terminal moves is to point to the eNodeB of the last process of portable terminal from the eNodeB of penult portable terminal process; Also can confirm the movement locus of said portable terminal according to the position recorded information; Infer the movement tendency of portable terminal, and then draw the direction that portable terminal moves.
According to the record in the recorded information of position order, calculate successively portable terminal in the timing time the distance between per two eNodeB of process, all that confirm to calculate are the distance that portable terminal moves apart from sum;
Perhaps for reducing amount of calculation; When in can put information on the throne the variation of tracking area being arranged; According to the order of the record in the recorded information of position; Calculate successively portable terminal in the timing time first eNodeB and the distance between last eNodeB in the tracking area of process; And portable terminal is in last eNodeB of last tracking area process and the distance of portable terminal between first eNodeB of back one tracking area process, and all that confirm to be calculated are the distance that portable terminal moves apart from sum.
If simple computation is in cycle timer write down in during this period of time the head and the tail TA of process or the distance between the eNodeB; If UE path looper in moving process, the actual displacement gap of displacement that then calculates and UE is very big, as shown in Figure 3; That get up with solid circles among the figure is the current TAList of UE; According to the situation of movement of UE, what UE promptly will move to is in the zone of TA5, if simple the employing calculated in cycle timer write down in during this period of time the head and the tail TA of process or the mode of the distance between the eNodeB; The distance of then being calculated will be the distance between TA1 and the TA4; With the actual conditions grave fault, shortened actual mobile distance greatly, have a strong impact on the optimized distribution of TA List.
For alleviating the storage burden of portable terminal, portable terminal just can be deleted the position recorded information of storage after receiving the tracking area tabulation, and picks up counting again and write down the portable terminal eNodeB information of process in proper order.
Further, because in real life, under a lot of situation; UE is after moving to certain direction; When returning, return along original path often, so, obviously can when returning, distribute TA List to play a significant effect of optimizing and simplifying UE if MME preserves UE position recorded information within a certain period of time; So MME is after the tracing section updating request and position recorded information that receive the portable terminal transmission; Also comprise: can the position recorded information of portable terminal be stored, and after the direction of determining motion of mobile terminals and speed, search the position recorded information of institute's mobile terminals stored; And compare with the current position of portable terminal and the direction of motion and speed, confirm the tracking area tabulation of portable terminal according to the compare of analysis result.
With the configuration flow of specific embodiment explanation tracking area tabulation, as shown in Figure 4 below, comprising:
Step S401, be in UE under the idle condition, detect and got into a new TA according to the system message (having comprised eNodeB ID and TAI in this system message) of eNodeB broadcasting;
Step S402, check whether this TAI is present among the TA List of UE,, continue execution in step S403 if exist, otherwise, execution in step S404;
Step S403, with in this eNodeB ID and the TAI journal put information on the throne; Upgrade the number of times that eNodeB or TA change simultaneously, wherein, the number of times that eNodeB or TA change is in the one-period of cycle timer, to write down; If one-period is full; Then restart timing and record, and, can guarantee that like this institute's information recorded is up-to-date in this cycle original institute recorded times information deletion.
Step S404, UE network side are initiated TAU;
When initiating TAU; Need on the standard base of 3GPP defined, the Last Visited Registered TAI field in the TAU Request message that UE sent out to be expanded; And the eNodeB ID that comprises journal of UE record and TAI, eNodeB or TA information and the timer of number of times during this period of time the position recorded information in the time interval from beginning to stopping that changes added, and this field is changed to UEMobility Info.
Step S405, MME extracting position recorded information;
MME the information of defined, also will extract this UE Mobility Info information in standard after receiving this TAU Request message.Though send the size that this position recorded information has increased message that UE sends out, the moving direction situation that adopting after the recorded information of position can be more accurate, describe UE in detail.
Step S406, MME compare position recorded information and the geographical location information of being stored and calculate, and draw direction and speed that UE moves, and generate corresponding TAList according to direction and the speed that UE moves;
When MME has been known behind the number of times that eNodeB that cycle timer is being write down in during this period of time from beginning to stopping or TA change; Can be through consulting corresponding position recorded information; That analyze during this period of time to be experienced is which eNodeB or TA on earth; The geographical location information of each eNodeB and TA is consulted and is analyzed under its administration of storing according to himself then; Calculate the approximate distance that UE moved in cycle timer timing during this period of time at last, and then draw the current mobile rate behavior of UE.
Because the UE situation about himself moving that has been journal; Form the position recorded information of a reflection UE situation of movement, and under many circumstances, the circulation that UE can do is back and forth moved in certain several TA; Simple this position recorded information of all extracting obviously can not play a positive role to the moving direction trend of differentiating UE for MME; To this situation, MME can the extracting section shift position information in the tabulation, promptly; Only extract the position recorded information after the UE circulation is moved, and these information also can reflect the mobile trend that UE is current.Because all eNodeB ID and TAI of process that UE is journal according to these ID signs, just can detect the mobile record of expression UE circulation.So MME is all to extract when extracting the record letter tabulation of UE position, also can extracting section, reject the record that expression UE circulation is moved according to the actual situation of movement of UE.In addition, MME also can extract according to the disposal ability of self;
After calculating respective, just can analyze in conjunction with the time interval that cycle timer write down and to draw the roughly speed that UE moves, it is that different UE distributes a different TA List coverage that MME can come according to this speed.In addition, MME can also preserve this speed, and TA List divides timing as a reference so that UE is carrying out next time,, if carry out current fast of speed ratio that TA List divides timing to calculate next time, can distribute more TA so that is; Otherwise, distribute less TA.
Step S407, TA List is sent to UE through TAU Accept message, in actual use, the message that can send TA List according to the actual conditions adjustment;
Step S408, UE delete the position recorded information of being stored after receiving TA List, and the line position recording of information of going forward side by side that picks up counting again.
Visible by Fig. 5; The TA that solid line surrounded representes the scope of former TA List, and the TAList that the TA that dotted line surrounded is not distributed according to the position recorded information is after the TA that pecked line surrounded then is the analysis position recorded information; The TAList that divides according to the movement tendency of UE; Under the rational situation of area coverage, reduced the number of times of TAU, improved validity to the portable terminal paging.
In the collocation method of the tracking area tabulation that the embodiment of the invention provides, as shown in Figure 6, the UE side need be carried out following steps:
Step S601, the eNodeB information sequence of the timing time of timer timing and received eNodeB broadcasting is recorded in the recorded information of position;
Step S602, during tracing section updating, send the position recorded information to MME in request;
Step S603, reception MME tabulate according to the tracking area of position recorded information configuration.
After receiving the tracking area tabulation of MME according to the configuration of position recorded information, the position recorded information that the UE deletion is stored, the line position recording of information of going forward side by side picks up counting.
