Description
Technical field
The present invention relates to communication technical field, be specifically related to registration area distribution method and application in a kind of wireless network.
Background technology
Current 3GPP (third generation partnership project) network develops to the direction of low time delay, two-forty, packetizing, 3GPP (third generation partnership project) has started LTE/SAE (Long TermEvolution, Long Term Evolution/System Architecture Evolution, system architecture evolution) research work can reduce time delay to provide a kind of, improve the network cheaply of user data rate, improvement power system capacity and covering.LTE only uses PS (packet switching) territory business, and bearer network is a full IP bearing.
On this basis, derive a lot of new network architectures, wherein, a kind of popular framework as shown in Figure 1:
Wherein, LTE RAN is the wireless access network of evolvement network, comprise logical node eNode B (evolution base station), CPS (Control Plane Server, chain of command server), logically with it as LTE-RAN Entity (Long Term Evolution radio access network entity).
EGSN (evolved GPRS Support Node) is GSN (the GPRS Support Node of evolution, GPRS Support Node), form by MME (Mobility Management Entity, Mobility Management Entity) and UPE (User Plane Entity, user entity).MME is used to manage and store MM (mobile management) context of UE, and the user is authenticated.UPE be used to the to terminate downlink data of UE of idle condition arrives UPE as downlink data, will trigger paging, preserves the context of UE simultaneously, as the IP address of UE and routing iinformation etc.
HSS (Home Subscriber Server, home subscriber server) is responsible for preserving user related information: user ID, numbering and addressing information; User security information: network insertions such as authentication and authentication control; Customer position information; User's master data information.
User Plane anchor (user's face anchor point) is a user entity of supporting that UE moves between different access systems, supports the switching between different access systems, remains unchanged during user's session.
Distinguish from logic function, eGSN is separated into MME and UPE.But from physical node, each logic entity has multiple compound mode, merges into a physical node as CPS and MME, UPE, and eNodeB is a physical node; Or eNode B and CPS merge into a physical node, and MME, UPE merge into physical node or the like.
In order in MME, to carry out mobile management, a new notion TA (Tracking Area has been proposed in the evolvement network, tracking area) follows the tracks of user position information, it is equivalent to the LA (lane place in the existing 2G/3G network, at circuit domain business), RA (route district, at packet switch domain service), URA (Acceditation Area), be the common name of CN/RAN side.
When the user when a TA moves to another TA, must initiate TAU (tracing section updating).
Have downlink data to arrive when UE is in the IDLE state, network will carry out paging in all sub-districts in the TA of user's registration.Because TA fixedly installs, and will cause frequent TAU when UE moves around on the TA border, promptly so-called " Ping-Pang " effect.UE passes through a lot of TA district fast and also can cause frequent TAU when high-speed cruising.This frequent TAU behavior, and in TA all cell paging UE, all can increase the reciprocal process of signaling in the system, will greatly waste system resource.
Frequent TAU for fear of the user moves around between TA and causes has proposed following solution in the prior art:
Characteristics (partially overlapping between the adjacent TA) at overlapping TA, make the eNode B that is in TA coincidence zone broadcast a plurality of TAI (tracking area identification) simultaneously on BCH (broadcast channel), defined UE selects to answer resident TA when TAU rule simultaneously: UE selects to reside in the nearest TA in position at TA center and current UE place.
This scheme has solved UE effectively and has moved around at the TA edge and produce " Ping-Pang " effect, but does not consider the movement velocity of UE.When the UE fast moving is passed through a plurality of TA, still can produce frequent TAU.
When UE passes through a plurality of TA fast, produce frequent TAU, proposed following solution in the prior art:
The motion feature of network based UE (UE translational speed, standby time etc.) carries out classification to TA; UE is according to displacement feature selecting TA level.TAI can adopt two kinds of methods to be provided with: a) different ranks is represented in the TAI segmentation; B) TAI is set to 9 binary modes of xxx-xxx-xxx, represents a rank for per 3, only needs just all other TAI of level under this sub-district as can be known of the minimum TAI of broadcasting rank in the sub-district.
The movement velocity that this scheme has reduced because of UE changes the frequent TAU problem that takes place, but the detection of its movement velocity and calculating are to be finished by UE, and energy consumption is than higher.
In addition, at many RAT (Radio Access Technology, wireless access technology) in the network, because UE is between different RAT (as network and the evolvement network of 2G/3G) when mobile, can change residing in different networks and the trigger network registration process, and frequent network registration process can cause great waste to interface-free resources.

Embodiment
Core of the present invention is to introduce the notion in dynamic registration district, make portable terminal carry out network registry or between different lane place, move or during periodic location update, generate the dynamic registration district by network side for it, each dynamic registration district comprises one or more lane place, when UE is mobile in this Acceditation Area, not needing to carry out the position upgrades, when UE shifts out this dynamic registration district or periodic location update, initiate update request to network side, network side is accepted the update request of UE and returns to UE to upgrade when accepting message, will send to UE for the dynamic registration district information that UE redistributes.
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
With reference to Fig. 2, Fig. 2 is the realization flow of registration area distribution method in the wireless network of the present invention, may further comprise the steps:
Step 201: portable terminal is carrying out network registry or is moving between different lane place or during periodic location update, network side is its generation dynamic registration district.
The present technique field personnel know, the UE Acceditation Area is meant that UE is registered to a zone of network, and UE does not need to initiate to register or position new technological process more in this zone when mobile.Acceditation Area can be the set of a TA or several TA or multiple RAT lane place (as RA, LA, URA, TA etc.).
In the present invention, introduce the notion in dynamic registration district, i.e. the attribute of network based UE, the RAT pattern of supporting as speed or the UE of UE, or according to the attribute of network as the configuration of network etc., dynamically is UE distribution Acceditation Area.
The dynamic registration district comprise the lane place granularity (such as, TA or RA or LA or URA or base station or sub-district) and this dynamic registration district in the Location Area Identification that comprised.Described Location Area Identification can be: TA sign or RA sign or LA sign or URA sign or Base Station Identification or cell ID etc., or the combination in any of above various signs.
For the ease of management to UE dynamic registration district, can represent the dynamic registration district of UE by the mode of tabulation, it forms structure as shown in Figure 3:
Wherein, Header partly illustrates the association attributes of node, for example, and node number, node type etc.Described node can be TA or RA or LA or URA or positions such as eNode B or Cell.
Node-1 to Node-n represents the Location Area Identification that comprised in the dynamic registration district, and this sign can be the sign of TA or RA or LA or URA or Node B or Cell (sub-district) etc., for example, and TA1, RA3, LA5, URA4 etc.
Certainly, according to actual needs, also can represent UE dynamic registration district by other describing mode.
UE is carrying out network registry or is moving between different lane place or during periodic location update, network side dynamically is its generation dynamic registration district.Can be that it generates the dynamic registration district specifically according to the attribute of the attribute of portable terminal or integrated network and portable terminal or the traffic performance or the network configuration cases of network.The generation method in UE dynamic registration district will be described in detail in the back.
Step 202: network side sent to portable terminal with the dynamic registration district relevant information (for example: the dynamic registration district tabulates) that generates when the Acceditation Area renewal was accepted.
The front is mentioned, network side can be that it generates the dynamic registration district according to the attribute of the attribute of portable terminal or integrated network and portable terminal or according to the traffic performance of network or according to the configuring condition of network, dynamically generate in the time of specifically can upgrading in each position, also can dynamically generate when the position is upgraded carrying out at all UE (need in conjunction with the network planning) at each UE.To be elaborated to this below.
1. center point prediction method, this method generates the dynamic registration district according to the attribute of portable terminal, mainly is that the position with UE recent registration or renewal is the center, according to user's kinetic characteristic, dynamically determines the Acceditation Area of a zone as UE.Can adopt following prediction rule:
Circular prediction rule: the stationary point of upgrading with the last Acceditation Area of user movement direction (sub-district or eNode B or TA/LA/RA/URA) is the center, multiply by the all-network node (with upgrading some node peer) that is comprised in the border circular areas that be radius update time in cycle with movement velocity and generates the dynamic registration district.
As shown in Figure 4, at first, UE is registered to TA3 during start, and under initial condition, UE, MME do not know the kinetic characteristic that UE is relevant, and MME accepts the registration of UE, and will return to UE for the dynamic registration district of its distribution, and the dynamic registration district of this moment is TA3; Then, when UE when TA3 moves to TA2, change (dynamic registration does not have TA2 in the district) has taken place in the position, the initiation position is upgraded, the kinetic characteristic that MME receives the position updating request of UE and reports or calculate, according to above-mentioned circular prediction rule, generate new dynamic registration district (comprising TA1, TA2, TA3), and return to UE.
The ellipse prediction: two stationary points upgrading with nearest twice Acceditation Area of user movement direction are the axle center, and the all-network node (with upgrading some node peer) that multiply by in the elliptical region that be radius update time in cycle with movement velocity generates the dynamic registration district.
As shown in Figure 5, at first, UE is registered to TA3 during start, and under initial condition, UE, MME do not know the kinetic characteristic that UE is relevant, and MME accepts the registration of UE, and will return to UE for the dynamic registration district of its distribution, and the dynamic registration district of this moment is TA3; Then, when UE when TA3 moves to TA2, change (dynamic registration does not have TA2 in the district) has taken place in the position, the initiation position is upgraded, the kinetic characteristic that MME receives the position updating request of UE and reports or calculate, according to above-mentioned oval prediction rule, generate new dynamic registration district (comprising TA1, TA2, TA3, TA4), and return to UE.
2. forward prediction method, this method is predicted with reference to the kinetic characteristic of network planning environmental characteristic (for example highway is along the line) and UE.Initiate at UE on the node location (expression tracking area TA or base station or position, sub-district) of registration or renewal, the time of upgrading according to moving direction, translational speed and the UE cycle of UE, obtain the radial distance of a UE, promptly multiply by and obtain a distance update time in cycle according to the UE translational speed, this distance has directivity, i.e. the moving direction of UE.Adopt certain rule, such as above-mentioned circular rule or oval rule or node sequence queueing discipline etc., the dynamic registration district of prediction UE.
As shown in Figure 6, at first, suppose that UE moves to the TA1 district from the below of TA1, resided in the dynamic registration district DTA1 (TA1, TA2, TA3); Then,, promptly arrive a new lane place, initiate the position and upgrade when UE moves to TA5 from dynamic Acceditation Area DTA1; At this moment, MME calculates a distance according to the UE translational speed and the update time in cycle (network configuration) of obtaining; Simultaneously, according to historical position information TA4, the TA5 of UE, and in conjunction with network planning environmental characteristic (for example highway is through TA4, TA5, TA6, TA7 direction), the moving direction of prediction UE is this direction; This distance that has direction is called radial distance.After MME obtains this radial distance, according to certain algorithmic rule (can network pre-configured), for example adopt oval prediction rule, two axle center then: one is the position of this registration of UE, another is the TA center of radial distance offside correspondence, radius is a radial distance, calculates an elliptical region, is included in this regional TA and forms dynamic registration district DTA2 (TA5, TA6, TA7); Perhaps adopt simple node sequence to arrange, all TA that are about in this radial distance process form the dynamic registration district.
3, generate the dynamic registration district according to network traffic characteristics
In the networking process, can generate several candidates' planning according to business model to same zone, for example: because different period network load difference in a day, the node in whole zone can be divided into 2 dynamic registration districts the morning, be divided into 3 dynamic registration districts afternoon, be divided into 1 dynamic registration district evening.Like this, when UE carried out the position renewal, the residing time period was that UE distributes suitable dynamic registration district when network side was initiated the position renewal according to UE.
For another example, according to the telephone traffic distribution situation in the network, for all UE distribute identical dynamic registration district at the same area.For example: on the higher zone of telephone traffic (as market, square, railway station, airport etc.) is the less dynamic registration district of UE allotment area; (as highway, spacious region, suburb etc.) are the bigger dynamic registration district of UE allotment area in the lower zone of telephone traffic.
4. generate the dynamic registration district according to network configuration cases
For all UE distribute identical dynamic registration district, the dynamic registration district here is dynamic longitudinally.For example: at the networking initial stage, number of users is less, gives the user in order to reduce the position update times, can distribute the dynamic registration district that comprises a plurality of TA, and the user moves between these TA can not initiate the position renewal.Along with the increase of number of users in the network, can distribute the dynamic registration district that comprises less TA to give the user, to reduce the paging amount in the dynamic registration district.
The present technique field personnel know, limitation signaling also is an important problem between different RAT.When UE is mobile between different RAT (as network and the evolvement network of 2G/3G), UE can reside in different network trigger network registration processes because of variation, and frequent network registration process also is a kind of great waste to system resource.
As shown in Figure 7, RA1 and RA2 are the route district (Routing Area) of existing 2G/3G, and the UE of 2G/3G will initiate RAU (Routing Area Update, Routing Area Update) process when RA of every replacing.Certainly UE also has periodic position updating process under the situation of not changing RA, and its effect is to make network understand UE at present also at network, prevents the UE deviated from network and the also constantly situation of paging UE generation of network.TA1, TA2, TA3, TA4 are the tracking areas (Tracking Area) of evolvement network.When the UE of a bimodulus or multimode moves, can cause frequent network registration process between these zones.For example: UE enters RA1 to the SGSN of 2G/3G registration, enters TA1 then to the MME/UPE of evolvement network registration, when it moves out TA1 and enters RA1, needs the registration to the SGSN of 2G/3G again.
Network side is the network that method that UE generates the dynamic registration district equally also is applicable to this many RAT (wireless access technology) coexistence among the present invention.
Suppose that the granularity in the dynamic registration district is TA/RA, the attribute of network based UE, as the speed of UE or the pattern of UE, or the attribute of network, as the configuring condition of network, for UE distributes the dynamic registration district.
For example, UE1 is a dual-mode terminal, and movement velocity is lower, so network can to its distribute dynamic registration district tabulation RA1, TA1, TA2}, UE1 is at RA1 like this, moves in the TA1, TA2 and need not initiate to register or updating message.
UE2 is a dual-mode terminal, and movement velocity is higher, so network can for its distribute dynamic registration district tabulation RA1, TA1, TA2, RA2, TA3}, UE2 is at RA1 like this, TA1, TA2 moves in the RA2, TA3 and need not initiate to register or updating message.
UE3 is the UMTS single-mode terminal, and speed is low, and network can { RA1}, UE3 moves in RA1 and need not initiate registration or updating message like this for it distributes the tabulation of dynamic registration district so.
UE4 is the UMTS single-mode terminal, the speed height, and network can { UE4 be at RA1 like this for RA1, RA2}, moves in the RA2 and need not initiate to register or updating message for it distributes dynamic registration district tabulation so.
Based on the notion in this dynamic registration district, the present invention also provides a kind of terminal process registration in wireless network, its realization flow as shown in Figure 8:
Step 801: portable terminal sends to network side and adheres to request, has the current location information of described portable terminal in this request.

Fig. 9 shows the realization flow of terminal of the present invention in the method for wireless network Position Updating, may further comprise the steps:
Step 901: network side is that portable terminal is determined the dynamic registration district.
Can also can use the dynamic registration district of acquiescence for it distributes the dynamic registration district when terminal is registered.If when terminal is registered, it is not distributed the dynamic registration district, also can initiate to be when the position is upgraded its distribution dynamic registration district for the first time in this terminal, so that in moving process subsequently, can determining whether carrying out the position according to the information in this dynamic registration district, it upgrades.Described dynamic registration district comprise the lane place granularity (such as, TA or RA or LA or URA or base station or sub-district) and this dynamic registration district in the Location Area Identification that comprised, described Location Area Identification is specially: TA (tracking area) sign and/or RA (route district) sign and/or LA (lane place) sign and/or URA (Acceditation Area) sign, and/or Base Station Identification and/or cell ID.
