Description
Technical field
The present invention relates to the handoff technique in the mobile communication system, particularly a kind of changing method based on translational speed.
Background technology
The situation that exists the multilayer net to cover in the mobile radio communication, so-called multilayer net covers and is meant that the overlay area of one deck sub-district is superimposed upon on the overlay area of another layer sub-district, the zone basis that the multilayer net covers is the size of cell coverage area wherein, the sub-district that can be divided into several different layers, the coverage maximum be top sub-district, the coverage minimum be the sub-district of lowermost layer, Gao Ceng sub-district often covers the sub-district of a plurality of relative low layers relatively.Such as global system for mobile communications (GSM a multilayer, Global System for Mobilecommunications) can have umbrella (Umbrella) sub-district, grand (Macro) sub-district, little (Micro) sub-district, (Pico) sub-district slightly from top to lowermost layer in the net, top umbrella cell can cover that a plurality of macrocells, macrocell can cover a plurality of Microcells, Microcell can cover a plurality of lowermost layer picocells.Being in the sub-district of one deck with a layer sub-district, is exactly with a layer sub-district such as Microcell and Microcell, and macrocell and macrocell also are with a layer sub-district; High-rise sub-district and low layer sub-district are exactly the different layers sub-district the different layers sub-district such as macrocell and Microcell.The low layer sub-district is superimposed upon replenishing as high-rise sub-district on the overlay area of high-rise sub-district, in order to improve network capacity, such as: Microcell is mainly used in two kinds of areas that cover in the macrocell in macrocell, a kind of is the hot zones of high traffic, shopping centre as prosperity, another kind is the covering blind spot of macrocell, as market place builet below the ground etc.; Picocell is mainly used in Microcell and covers the intensive room area of user, as the great hall etc., with further raising network capacity.As travelling carriage (MS, when MobileStation) mobile, usually in order to allow travelling carriage be positioned at best overlay area so that obtain preferable speech quality, higher bandwidth, and for the cutting off rate that reduces travelling carriage etc., network side can allow travelling carriage between with layer sub-district or switch between the different layers sub-district.Generally speaking, network side can judge whether travelling carriage is in cell edge, makes switch decision then according to the measurement report that travelling carriage reports, and comprises the information such as signal quality, signal level of travelling carriage in the measurement report that travelling carriage reports usually.The Timing Advance that network side also can be known according to oneself (TA, Time Advance) is estimated the distance between travelling carriage and the center of housing estate point, judges travelling carriage present located position, and then determines whether travelling carriage is switched.
The shortcoming of prior art is: if travelling carriage is relatively-stationary, even in dense cell networks, also can seldom cause irrational handover, but, if the translational speed of travelling carriage is very big for cell size, it is fast moving, translational speed such as travelling carriage is 15m/s, and the Microcell under it and the radius of adjacent Microcell are about 10m, if handled by the Microcell net this moment, might be because travelling carriage fast moving continually between each Microcell, make this fast moving cause considerable handover, make and call out very difficulty of control, frequent handover operation taking place, also can increase the control burden of system, reduces service quality.

Description of drawings
Fig. 1 is based on the handoff procedure schematic diagram of translational speed in the embodiment of the invention GSM network.
Embodiment
Development along with location technology, in real time the translational speed that obtains travelling carriage can realize, at present by location technology, travelling carriage can obtain position information such as self longitude and latitude and translational speed, based on this, the present invention proposes the switching mode that triggers based on the travelling carriage translational speed.
Following with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
See also Fig. 1, Fig. 1 is based on the handoff procedure schematic diagram of translational speed in the GSM network.As shown in Figure 1, the implementation procedure of switching based on translational speed in the GSM network is as follows:
The step 101: (MSC of mobile switching centre, Mobile Switch Center) sends message by task registration (REGISTER) message to MS, carry the translational speed threshold value in the message, notice MS reports when translational speed reaches certain threshold value, and this threshold value is that MSC is provided with in advance.
As for REGISTER message, REGISTER is a message bearing in the prior art, the carrying upper-layer service, the purposes of REGISTER message is: when MSC needs MS to carry out certain task, send REGISTER message to MS, report when the performance of appointment reaches certain threshold value by the information notice MS that carries in the message, MS receives after the REGISTER message according to the content in the message self specified performance is monitored, when performance reaches the threshold value of indication in the message, MS triggers and reports, be that MS sends REGISTER message to MSC, comprise in the message to allow MSC know that self performance has reached the information of assign thresholds.MSC is to have increased the translational speed threshold information in the REGISTER of prior art message to the REGISTER message that MS sends in the step 101.REGISTER message belongs to signaling message, and signaling message is to control the information that is exchanged in order to carry out certain in the communication system, and the form of signaling message is observed certain agreement and standard.
Step 102:MS starts positioning flow, monitors the translational speed of self.It can be to initiate self that MS starts positioning flow, also can be to start by MSC, and can also be that MS and MSC start jointly, the method that specifically starts positioning flow belongs to prior art, and the method how MS monitors self translational speed also belongs to
Prior art.
Step 103: when the translational speed of MS reaches threshold value, MS reports to MSC by REGISTER message, herein report that can be MS show that to MSC self translational speed has reached threshold value, also can be that MS directly sends handoff request to MSC, request MSC switches self.
Step 104:MSC initiates switching flow after receiving reporting of MS, MS is switched in the different layers sub-district, herein, when in the different layers sub-district, a plurality of candidates' sub-district being arranged, MSC can select a sub-district in a plurality of sub-districts of candidate, MS is switched in the selected sub-district.How MSC all belongs to prior art to the method that MS initiates switching flow, how MSC selects sub-district, a MSC how MS to be switched in the selected sub-district in fixed a plurality of candidate cells.
MSC described in the step 104 switches to MS in the different layers sub-district, MSC may switch to high-rise sub-district by the low layer sub-district with MS, also MS may be switched to the low layer sub-district by high-rise sub-district, so still switch to high-rise sub-district by the low layer sub-district to switch to the low layer sub-district by high-rise sub-district, that is to say and how to determine candidate cell, MSC can decide according to the use characteristic of MS and in conjunction with the translational speed threshold value that sets, specifically, among the present invention, translational speed feature according to travelling carriage, the mobile subscriber can be divided into domestic consumer and special user, so-called special user is meant the user who has certain particularity on translational speed, such as: be in high-speed moving state etc. usually, so, other user except that the special user just is called domestic consumer.For domestic consumer, when the translational speed of corresponding MS was brought up to setting threshold, MSC can switch to high-rise sub-district by the low layer sub-district with it; And judge according to its use characteristic that for the special user usually all on the train of high-speed mobile, then when the translational speed of corresponding MS was reduced to setting threshold, MSC can switch to the low layer sub-district by high-rise sub-district with it such as this special user.
In actual applications, the described MS of step 102 starts positioning flow and monitors self translational speed among Fig. 1, can carry out after step 101, also can carry out before step 101.The situation of carrying out before step 101 is: MSC gives the translational speed threshold notification before the MS, MS has started positioning flow, and monitor self translational speed at any time, but do not report, only after receiving the REGISTER message that MSC sends, MS just reports to MSC when self translational speed reaches the translational speed threshold value of appointment in the message.
In the step 101 of Fig. 1, MSC sends message by REGISTER message to MS, and in step 103 when the translational speed of MS reaches threshold value, MS gives MSC by the REGISTER information reporting.Except using the method for REGISTER message, also can substitute REGISTER message by other signaling messages, as long as MSC is by comprising the translational speed threshold value at interior signaling message in step 101, notice MS reports when translational speed reaches certain threshold value, accordingly, when the translational speed of MS reached threshold value, MS got final product to MSC by corresponding signaling message report in step 103.
MSC gives MS preset threshold size mainly relevant with the use characteristic of the radius of MS affiliated subdistrict, MS among the present invention.Be domestic consumer, be arranged in Microcell and this Microcell that radius is 10m and be included in the macrocell that radius is 3Km such as: MS, in this case, Microcell is the low layer sub-district, macrocell is high-rise sub-district, can be made as 10m/s this moment with the translational speed threshold value, then when the translational speed of MS surpasses 10m/s, according to method shown in Figure 1, MS will be that to switch to high-rise sub-district be macrocell to Microcell by the low layer sub-district; Be included in the umbrella cell that radius is 35Km if MS is domestic consumer, be positioned at macrocell and this macrocell that radius is 10Km, in this case, macrocell is the low layer sub-district, umbrella cell is high-rise sub-district, can be made as 100m/s this moment with the translational speed threshold value, then when the translational speed of MS surpasses 100m/s, according to method shown in Figure 1, MS will be that to switch to high-rise sub-district be umbrella cell to macrocell by the low layer sub-district; And if MS is the special user, this special user is usually in high-speed mobile, the umbrella cell that now is arranged in radius and is 35Km moves with the translational speed of 100m/s, if wish when the translational speed of MS drops to certain value it is switched to certain macrocell in a plurality of macrocells that this umbrella cell comprises, and the radius of these macrocells is approximately 3Km～5Km, in this case, umbrella cell is high-rise sub-district, macrocell is the low layer sub-district, can be made as 20m/s this moment with the translational speed threshold value, then when the translational speed of MS reaches 20m/s, according to method shown in Figure 1, MS will by high-rise sub-district be umbrella cell to switch to certain low layer sub-district be certain macrocell, the MSC method that how MS switched to certain macrocell in a plurality of macrocells belongs to prior art herein.How to judge that as for network side the method which sub-district MS belongs to belongs to prior art.
The above implementation method in the GSM network, switching based on translational speed, technical solution of the present invention also can be generalized in all mobile communication system and uses, such as in code division multiple access (CDMA), Wideband Code Division Multiple Access (WCDMA) (WCDMA), CDMA2000, Personal Handyphone System, big well-informed or the like system, its implementation all is that network side is given travelling carriage a translational speed threshold notification earlier, after travelling carriage is notified when the translational speed of self reaches threshold value the informing network side, network side is received to trigger after the notice of travelling carriage and is switched.
