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 list.
Background technology
LTE(Long Term Evolution) be 3GPP(3rd Generation Partnership Project, third generation partner program) mobile wireless network of future generation, compare existing 3G network, there is more high bandwidth, the features such as lower time delay.
LTE network is the network of an all-IP, in wireless side by RNC(Radio Network Controller radio network controller) and NodeB(base station) synthesize a network element eNodeB(evolution base station), the location management of whole network also adds the management of Route Area from original lane place, be evolved into TA(Tracking Area, tracking area) management, unique sign TAI(Tracking Area Identifier for each tracking area, tracking area identification) identify.Due to the One's name is legion of tracking area in LTE network, UE can produce a large amount of tracing section updating signalings in frequent mobile process under idle condition, and these renewal signalings can cause larger load pressure to core net, also can waste in a large number the resource of network simultaneously.
In this case, it in 3GPP standard, is the mobile management of UE, defined specially a completely new concept, TA List(Tracking Area List, tracking area list), network side is that UE distributes a TAList, as shown in Figure 1, a plurality of TA in tracking area list, have been comprised, and under each TA, comprised a plurality of communities, when UE moves under idle condition, as long as the TA of process be all present in distributed TA List, UE, just without frequent launch position update request, has reached the object of saving Internet resources so.Only have and detect it and entered a tracking area TA who has not yet registered as UE, and this TA is not present in the TA List distributing before network, UE just can initiate TAU(Tracking Area Update, tracing section updating).
The MME(Mobility Management Entity of network side, mobile management entity) be the configuration of TA List and issue entity, when UE carries out TAU or attachment flow, the TAI(that MME can be according to UE be registered in MME at a front TAU or while adhering to is provided in TAU Request message by UE), the TAI(of current UE place TA provides by current eNodeB) and UE subscription data in information carry out the determining of the TA List of UE, when determining, need to consider the direction of TA List and range size etc.And in new TA List, can comprise the several or a plurality of TA in original TA List, to avoid ping-pong.Finally, MME can be handed down to UE by new TA List in Attach Accept, TAU Accept or GUTI Relocation Command message.
It should be noted that, while moving in the TA that UE comprises at TA List under idle condition, the TA at place when UE initiates TAU before in the MME of network side to the location of UE being still, when network side is initiated the paging to UE, can carry out in all TA in the TA of distributed to UE List.
Although, designed the concept of TA List, can reduce the number of times of UE numerous TAU carrying out of mobile time-frequency under idle condition, TA List is larger, the number of times of TAU is just fewer, but due to when network is during at paging UE, understands in all TA that cover at whole TA List and carry out paging, if TA List coverage is larger, the also limited resource of consumption network greatly.
The size of the size of visible paging domain and TA List is conflict.TA List crosses conference makes paging zone excessive, while calling out UE, can increase the unnecessary resource overhead of network; And conversely, TA List is too small, although call out the scope of UE, diminish, but can cause UE between different TA, to carry out frequently position renewal, not only can greatly increase the load of network, reduce the performance of network, simultaneously also can consume UE own resources, as battery flying power etc.
The present inventor finds, due to MME be according to UE, provide before TAU or adhere to the TAI in when registration and the TAI of current UE position that eNodeB provides and the subscription data of some UE carry out new TA List and distribute, and such distribution method is not very effective.On the one hand, only, by two TAI, MME can not judge the direction that UE moves very effectively, accurately, and the direction that such distributed TA List may move with UE in direction is inconsistent, thereby unnecessary radio resource consumption while causing paging, has also increased the frequency of TAU; On the other hand, MME also cannot be known the movement rate that UE is current, cannot determine that in TA List, to distribute how many TA to be only on earth the most effective, thereby cause distributed TA List excessive or too small.

Embodiment
The embodiment of the present invention provides a kind of collocation method, system and device of tracking area list, when distributing tracking area list for UE, get the position recorded information that UE records simultaneously, according to this information, determine the factors such as direction that UE moves and movement rate, thereby the direction moving according to UE and movement rate, can reasonably distribute tracking area list, both controlled the coverage of tracking area list, reduce again the frequency of TAU, and then improved the performance of network.
The collocation method of the tracking area list that the embodiment of the present invention provides is in paging zone size and the list of TA List(tracking area) carry out balance between size, by the optimization to TA List, both met the validity of paging, and reached again and reduce unnecessary TAU signaling consumption.Because the situation of movement of UE only has UE self the clearest, so the embodiment of the present invention is carried out record by UE to the situation of movement of self, and this is recorded in and reports network MME while initiating TAU, make MME grasp the motion conditions of UE, MME is understanding on the basis of UE motion conditions, again by analysis and calculate, design applicable TA List.
The TA List generating due to MME designs according to the up-to-date situation of movement of UE, and the situation that each UE moves is generally different, according to the different motion situation of different UEs, MME can design different TA List, like this, except can balancing paging district and TA List size between contradiction, can also prevent that to UE, send a large amount of UE in same place that same TA List causes initiates TAU to network simultaneously, cause network load moment to increase.
As shown in Figure 2, the collocation method of the tracking area list that the embodiment of the present invention provides, comprising:
The position recorded information that step S201, mobile terminal receive send, in the recorded information of position journal the eNodeB information of mobile terminal process, and the time span of timer record;
Step S202, analyze the position recorded information of mobile terminal, determine direction and the speed of motion of mobile terminals;
Step S203, according to the direction of motion of mobile terminals and speed, the tracking area list of configuration mobile terminal, and sends to mobile terminal.
In step S201, mobile terminal can send to MME in the lump by position recorded information and tracing section updating request, can also further position recorded information be carried in tracing section updating request and be sent, carrying mode is: the request of expansion TAU Request(tracing section updating) the Last Visited Registered TAI field in message, writing position recorded information in the field after expansion.
Because UE is under idle condition, every through a TA, capital receives that eNodeB broadcasts himself eNodeB ID and TAI, and UE can be by these a few eNodeB ID and TAI one by one after correspondence, in sequential storage put information in place, position recorded information represents a situation of movement of UE with regard to can completely like this, position recorded information can be the eNodeB ID/TAI list of reflection UE situation of movement, also can only record eNodeB information, as long as can eNodeB of unique identification, can further reduce the data volume that sends to MME like this, MME is after receiving position recorded information, if only recorded eNodeB information in the recorded information of position, MME can be according to the division of tracking area, determine the tracking area at this eNodeB place.
For further controlling the size of TAU Request message, prevent from excessively after TAU Request extension of message taking too much system resource, can maximum length be set for extended field, UE constantly sequentially writes eNodeB ID/TAI to position recorded information in moving process, when position recorded information surpasses this length,, top eNodeB ID/TAI record can be deleted, 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 in 3GPP24.301, TAU Request message size is at least 80 bytes, and under homogeneous networks covers, sign TA only needs two bytes, so can think the expansion that Last Visited Registered TAI field is carried out, can significantly not increase the size of TAU Request message, therefore can't to network side, bring very large impact because message capacity becomes large.
Because UE just can receive based on existing hardware the broadcast message with its sign that location eNodeB sends when mobile, so hardware need to additionally do not increased in UE, generate position recorded information, only the eNodeB ID/TAI information in broadcast message need to be identified and stored, can significantly not increase the hardware complexity of UE.
In step S202, MME analyzes the position recorded information of mobile terminal, according to the eNodeB ID recording in the recorded information of position and TAI number, can roughly determine the distance of motion of mobile terminals, according to the time span recording in the recorded information of position, determine the speed of motion of mobile terminals again.
MME can estimate the relative position of eNodeB and TA according to eNodeB and the TA information of storage, determines the direction of motion of mobile terminals.
For further determining more accurately direction and the speed of motion of mobile terminals, in MME, can store the geographical location information of eNodeB and tracking area, this geographical location information can be GPS locating information, can manually input MME or allow eNodeB offer MME by the mode automatically reporting When building their networks, MME can consult or calculate actual distance size and the true relative position between each eNodeB or TA in this part of geographical location information table, so just can be according to the eNodeB of storage and the geographical location information of tracking area, and the position recorded information of mobile terminal, determine more accurately direction and distance that mobile terminal moves, the time span recording in the distance moving according to mobile terminal again and position recorded information, determine the rate travel of mobile terminal.
MME determines moving direction and the rate travel of UE according to position recorded information.The moving direction of UE can help MME to determine the bearing of trend of tracking area in distribution T A List, and MME is informed in behind the region that UE most possibly enters in the future, the TA in these regions can be assigned in TA List; The rate travel of UE can help MME to determine the coverage of tracking area in TA List, allows MME know the situation of the speed that nearest a period of time of UE moves, thereby determines will distribute how many TA at TA List on earth.For the fast situation of speed, in TA List, the coverage of tracking area can be distributed largerly; For the slow situation of speed, in TA List, the coverage of tracking area can be distributed smallerly.So, not only can solve the generation of the unnecessary signaling message of TAU frequently of UE, can also in most possible direction and in optimal scope, to UE, carry out paging.
Further, because the rate travel of mobile terminal may change, for example user is from transferring on foot by bus, so in order to make MME can calculate the up-to-date rate travel situation of mobile terminal, can be so that the timer of mobile terminal carries out periodicity timing, and in put information in place record move terminal the change number of times of eNodeB of process, timer is when the time span of record reaches the predefined time cycle, restart timing, when starting timing at every turn, again record move terminal the change number of times of eNodeB of process, if detecting, UE entered a new TA, and need to carry out TAU, stop at once timing, and keep number of times information that current eNodeB and TA change and the timing time of timer.Like this MME according in the recorded information of position, record the change number of times of eNodeB and the eNodeB information of process determine in the time span of timer record, the displacement of mobile terminal, calculate again the rate travel of mobile terminal, due to timer meeting reclocking when reaching timing cycle, so this translational speed is the most current speed of mobile terminal.
When determining the direction that mobile terminal moves, can simply determine that the direction that mobile terminal moves is to point to mobile terminal finally by the eNodeB crossing from the eNodeB of penultimate mobile terminal process, also can determine according to position recorded information the movement locus of described mobile terminal, infer the movement tendency of mobile terminal, and then draw the direction that mobile terminal moves.
According to the record order in the recorded information of position, calculate successively mobile terminal in timing time distance between every two eNodeB of process, determine that calculate all are the distance that mobile terminal moves apart from sum;
Or for reducing amount of calculation, while having the variation of tracking area in can put information in place, according to the record order in the recorded information of position, calculate successively mobile terminal in timing time first eNodeB in the tracking area of process and the distance between last eNodeB, and mobile terminal last tracking area through last eNodeB and mobile terminal after distance between first eNodeB of a tracking area process, determine that calculate all are the distance that mobile terminal moves apart from sum.
If simple computation at cycle timer, record during this period of time in the head and the tail TA of process or the distance between eNodeB, if UE is path looper in moving process, the actual displacement gap of the displacement calculating and UE is very large, as shown in Figure 3, that in figure, by solid circles, get up is the current TA List of UE, according to the situation of movement of UE, what UE will move to is in the region of TA5, if simple, adopt calculate at cycle timer, record during this period of time in the head and the tail TA of process or the mode of the distance between eNodeB, the distance calculated will be the distance between TA1 and TA4, with actual conditions grave fault, greatly shortened the distance of actual movement, the optimization that has a strong impact on TA List distributes.
For alleviating the storage burden of mobile terminal, mobile terminal, after receiving tracking area list, just can be deleted the position recorded information of storage, and restarts the eNodeB information of timing and record move terminal order process.
Further, due in real life, in a lot of situations, UE is after moving to certain direction, when returning, along original path, return often, so if MME preserves UE position recorded information within a certain period of time, obviously can when returning, distribute UE TA List to play a significant effect of optimizing and simplifying, so MME is after receiving the tracing section updating request and position recorded information of mobile terminal transmission, also comprise: the position recorded information of mobile terminal can be stored, and after determining the direction and speed of motion of mobile terminals, search the position recorded information of stored mobile terminal, and compare with the current position of mobile terminal and the direction of motion and speed, according to compare of analysis result, determine the tracking area list of mobile terminal.
With the configuration flow of specific embodiment explanation tracking area list, as shown in Figure 4, comprising below:
Step S401, the UE under idle condition, according to the system message (having comprised eNodeB ID and TAI in this system message) of eNodeB broadcast, detect and have entered a new TA;
Step S402, check whether this TAI is present in the TA List of UE, if existed, continue execution step S403, otherwise, execution step S404;
Step S403, by this eNodeB ID and TAI journal put information in place, upgrade the number of times that eNodeB or TA change simultaneously, wherein, the number of times that eNodeB or TA change is to record in the one-period of cycle timer, if one-period is full, restart timing and record, and original recorded number of times information deletion, can guarantee that like this information recording is up-to-date within this cycle.
Step S404, UE network side are initiated TAU;
When initiating TAU, need in the standard base of 3GPP defined, to the Last Visited Registered TAI field in the TAU Request message that UE sent out, expand, and the eNodeB ID that comprises journal of UE record and TAI, eNodeB or the TA information of number of times and the timer position recorded information in time interval during this period of time from starting to stopping that changes is added, and this field is changed to UEMobility Info.
Step S405, MME extracting position recorded information;
MME, after receiving this TAU Request message, the information of defined, also will extract this UE Mobility Info information in standard.Although 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 contrast position recorded information and the geographical location information stored and calculate, and draw direction and speed that UE moves, and the direction moving according to UE and speed generate corresponding TAList;
When MME has been known after the number of times that the eNodeB that recording in during this period of time from starting to stopping at cycle timer or TA change, can be by consulting corresponding position recorded information, analyzing what during this period of time experienced is which eNodeB or TA on earth, then lower each eNodeB of its administration storing according to himself and the geographical location information of TA are consulted and are analyzed, finally calculate the approximate distance that UE moves in cycle timer timing during this period of time, and then draw the rate behavior of the current movement of UE.
Due to 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, UE can do loopy moving back and forth in certain several TA, for MME, simple this position recorded information of all extracting obviously can not play a positive role to differentiating the moving direction trend of UE, for this situation, the information of MME in can the list of extracting section shift position,, only extract the position recorded information after UE loopy moving, and these information also can reflect the mobile trend that UE is current.All eNodeB ID and TAI due to the UE process that is journal, according to these ID signs, just can detect the record of expression UE loopy moving.So MME is all to extract when extracting the record letter list of UE position, also can extracting section, according to the situation of movement of UE reality, reject the record that represents UE loopy moving.In addition, MME also can extract according to the disposal ability of self;
After calculating respective distance, the time interval of recording in conjunction with cycle timer just can be analyzed the roughly speed that show that UE moves, and MME can come to distribute a different TA List coverage for different UE according to this speed.In addition, MME can also save this speed, so as UE on carrying out once TA List divide timing as a reference, that is, if carry out current fast of speed ratio that TA List divides timing to calculate next time, can distribute more TA so; Otherwise, distribute less TA.
Step S407, by TAU Accept message, TA List is sent to UE, in actual use, can send according to actual conditions adjustment the message of TA List;
Step S408, UE, after receiving TA List, delete the position recorded information store, and restart the timing line position recording of information of going forward side by side.
As seen from Figure 5, the TA that solid line surrounds represents the scope of former TA List, the TA List that the TA that dotted line surrounds does not distribute according to position recorded information, after the TA that pecked line surrounds is analysis position recorded information, the TA List dividing according to the movement tendency of UE, in the rational situation of area coverage, reduced the number of times of TAU, improved the validity to mobile terminal paging.
In the collocation method of the tracking area list providing in the embodiment of the present invention, as shown in Figure 6, UE side need to be carried out following steps:
Step S601, by the eNodeB information journal put information in place of the timing time of timer timing and received eNodeB broadcast;
Step S602, in request, during tracing section updating, to MME, send position recorded information;
Step S603, reception MME are according to the tracking area list of position recorded information configuration.
Receiving MME according to after the tracking area list of position recorded information configuration, UE deletes the position recorded information of storing, and starts the timing line position recording of information of going forward side by side.
UE can also by the change number of times of eNodeB of process be recorded in the recorded information of position, timer is when the time span of record reaches the predefined time cycle, restart timing, when starting timing at every turn, again record the change number of times of eNodeB of process.
