Description
Technical field
The present invention relates to mobile communication technology, particularly the load changing method of cross base station controller in the mobile communication system.
Background technology
Along with being the high-tech development of sign with the communication technology and computer technology, the great variety of making rapid progress has taken place in people's life, and interpersonal information transmission is more and more closer, mode is also more and more diversified.The development of cellular mobile communication brings great convenience to the user, the three generations has been experienced in its development at present, be respectively that early eighties is with frequency division multiple access (Frequency Division Multiple Access, abbreviation " FDMA ") technology is basic first generation analog mobile communication system, the early 1990s is with time division multiple access (Time Division Multiple Access, abbreviation " TDMA ") technology is the second generation digital cellular mobile communication systems on basis, and of new generation at present moving and PCS Personal Communications System, promptly move and PCS Personal Communications System for the third generation on basis with code division multiple access (Code Division Multiple Access is called for short " CDMA ") technology.The third generation moves a focus that becomes field of telecommunications with the research and development of PCS Personal Communications System, three main world standards have been formed, Wideband Code Division Multiple Access (WCDMA) (Wideband CodeDivision Multiple Access, be called for short " WCDMA ") is exactly one of technology of wherein tool potentiality.
In the WCDMA system, switching is a key technology supporting user's global roaming, and it is an important mobile management function, is that cellular system is exclusive, and it directly influences the performance of whole system.Those of ordinary skill in the art know that so-called the switching is exactly to move on to another sub-district from a sub-district when travelling carriage (Mobile Station is called for short " MS ") in communication process; Or, external interference descends because of causing speech quality; Or too many because of the user in the sub-district, in the time of can't guaranteeing that all users normally use, MS must be transferred to the communication service switching on the new channel, continues to keep communication.Link between former base station and the MS may be replaced by the link between new base station and the MS.Switching type has multiple mode classification, sets up situation about discharging and can be divided into according to being connected between MS and the network: More Soft Handoff, soft handover and direct-cut operation.Distinguish according to switch reasons, can be divided into edge switching and load substantially and switch.Those of ordinary skill in the art know, the edge switch be exactly transmission quality still can situation under, if MS is connected in the time of improving overall level greatly with another sub-district, can change the Serving cell of MS, may be contradictory but the edge switches with the transmission quality that this locality is optimized, can not carry out the edge when transmission quality is bad and switch.And load is switched, it is exactly when a small area jam and adjacent cell when idle, the traffic carrying capacity of carrying out is switched, business between the switching energy balance sub-district of this load Network Based, can prevent cell-overload, but to this switching handled of being sure to, because it contradicts with the edge switching criterion, because this switching will inevitably be upset plot planning, increase the interference level of surrounding area.
Above-mentioned is that the edge switches or the load switching all is to be initiated by base station controller.The accuracy of the information of the switching target small area that the efficient of switching is often recognized with base station controller is in close relations.Especially in the load handoff procedure, the situation that load is switched is varied.When needs carry out the load switching, no matter be to be in what situation, base station controller all must fully be understood the present load information of Target cell.Here consider in two kinds of situation generally: if Target cell and cell-of-origin are under the control of same base station controller, and base station controller is responsible for allocation of radio resources, it understands the loading condition of each sub-district in institute's compass of competency naturally so, promptly both understood the load information that Target cell is also understood the cell-of-origin, so the load handoff algorithms is just very simple.If but Target cell and cell-of-origin are by different base stations control management, the load that typical situation is interdepartmental system is switched, the base station controller of Target cell and cell-of-origin correspondence may be positioned at (the Mobile Switching Center of same mobile switching centre, be called for short " MSC ") or stride MSC, this switching may be to switch to global system for mobile communications (Global Systemfor mobile Communication from the WCDMA system, be called for short " GSM ") system or opposite, so this moment situation will complexity how, the load handoff algorithms is just very complicated, causes load switching efficiency in this case low.
In the prior art, when switching in the face of the load under the situation of handling more complicated, as shown in Figure 1, comprise user 103 in the broadband CDMA system 10, it is by base station 102 connecting systems, base station controller 101 is responsible for control base station 102, and is connected by Iu interface 104 with mobile switching centre 100.In WCDMA, the base station controller fork can be described as radio network controller (Radio NetworkController is called for short " RNC "), and the base station can be described as Node B (Node B) again.
Another system is a global system for mobile communications 11, wherein comprises user 113, and it is by base station 112 connecting systems, and base station controller 111 is responsible for control base station 112, and is connected by A interface 114 with mobile switching centre 110.
The base station controller of hypothetical target sub-district and cell-of-origin correspondence is positioned at two different MSC, and is to switch to gsm system or opposite from the WCDMA system.Be that user 103 in the broadband CDMA system 10 need switch under the channel in the global system for mobile communications 11, perhaps the user 113 in the global system for mobile communications 11 need switch under the channel in the broadband CDMA system 10, base station controller will be understood the load information of Target cell, can be by following two kinds of means:
First kind of mode:, directly between the base station controller of two systems, transmit load information by the Iur-g interface 12 that between base station controller 101 and base station controller 111, increases newly; Base station controller has separately been known the load information of Target cell, just can make and whether carry out the decision-making that load is switched.
The second way: transmit cell load information by A interface or Iu interface to affiliated MSC by base station controller separately respectively.Be that base station controller 111 transmits this cell load information by A interface 114 to mobile switching centre 110, perhaps base station controller 101 transmits this cell load information by Iu interface 104 to mobile switching centre 100.Be at last between mobile switching centre 110 and the mobile switching centre 100 by corresponding network exchange cell load information each other, the base station controller that is issued to separately again to be had jurisdiction over makes whether carrying out the decision-making that load is switched by it.
In actual applications, there is following problem in such scheme: needs add or revise interface, cause the change of Access Network and the many network elements of core net, also will carry out interoperability test again to new interface, and are with high costs, difficult in maintenance.
Cause the main cause of this situation to be, collection, analysis, the processing of the target cell information that in the prior art scheme load is switched are finished by base station controller, load for cross base station controller is switched, and must communicate by new interface between the different base station controller.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of mobile communication system load changing method, makes the load switching of cross base station controller not need to revise or add interface, directly realizes on conventional network equipment.
For achieving the above object, the invention provides a kind of mobile communication system load changing method, comprise following steps,
The A base station controller sends load and handovers request to mobile switching centre;

It is described best target cell that the sub-district of available resources probability maximum described in the adjacent area table of described cell-of-origin is selected by described mobile switching centre;
Wherein, the described available resources probability of all sub-districts in the adjacent area table of the adjacent area of described cell-of-origin table, described cell-of-origin is pre-configured.
Described step B1 also further comprises following substep,
The adjacent area table of described cell-of-origin is inquired about by described mobile switching centre according to the described load handoff request of receiving, if described Target cell at random is not included in the adjacent area table of described cell-of-origin, then add described Target cell at random to the adjacent area table of described cell-of-origin;
Statistical information and configuration information in described mobile switching centre according to all sub-districts in the adjacent area table of described cell-of-origin calculate described available resources probability;

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
The present invention directly adopts MSC to carry out collection, analysis, the processing of the target cell information of load switching, MSC finishes that Target cell load judgment, the Target cell that load switches selected, the load switching time is determined thus, makes load between different base station controller or the different system switch can efficiently to finish and irrelevant with each base station controller.Wherein, the target cell information among the MSC can obtain by initial configuration, also can reduce the implementation complexity that load is switched by the message of radio network controller (Radio Network Control is called for short " RNC ") is learnt to obtain.The RNC here also can be referred to as base station controller.In addition, configuration informations such as the statistical informations such as the current number of calls of MSC side by the sub-district, position update times and the maximum number of calls come the available resources probability of calculation plot, judge that with this whether feasible load of sub-district switch Target cell and that select optimum load to switch, improve the reliability that load is switched.
The present invention attempts to solve with a kind of simple technology the load switching of cross base station controller, avoids that existing network is carried out bigger upgrading and changes.Typically be applicable to but be not limited to the WCDMA system and switch to the load of gsm system.
By inventive principle as can be known, the primary problem that solves of the present invention is to adopt certain mode to allow MSC understand target to carry out the target cell information that load is switched.Those of ordinary skill in the art know, position updating process is a basic function of mobile management, it is by attaching position register (HomeLocation Register, abbreviation " HLR "), the logic cooperation is finished between the MSC/ VLR Visitor Location Register entities such as (Visitor LocationRegister are called for short " VLR ").HLR record portable terminal current location information and all customer data; The VLR record roams into the relevant user data by the portable terminal in this VLR control position district; The location registers process of MSC handle mobile terminal, with portable terminal dialogue and with HLR, VLR interactive information.The position is upgraded and is comprised location registers, periodic location registration, user data deletion etc.This shows the statistical information that in MSC, generally all has based on the sub-district about the position renewal.And portable terminal can carry out periodic position and upgrade, in MSC with regard to respective record in a time period T position update times LocUpNum, this numerical value has reflected this sub-district potential user's number substantially; Also write down the interior maximum number of calls CallNumbusyH of busy period T of every sub-district simultaneously, this numerical value can be represented the maximum available resources quantity of sub-district, and what particularly point out is that this numerical value is statistical value, very useful when network of network is planned, because Internet resources are according to this value configuration; Except above numerical value, the current number of calls CallNumCurrent of the current area of record also can be utilized in the MSC, and this value defined is the interior number of calls of a period of time T before the current time.After having had above three numerical value, just can define resource probability AresPro, this value defined is as follows:
AResPro＝(CallNumbusyH-CallNumCurrent)/LocUpNum
Its meaning has been to describe a sub-district is accepted a resource request again and can not be caused cell-overload under current state possibility.Such as when CallNumCurrent is very big (certainly can not greater than CallNumbusyH), show that interior this sub-district of a period of time T before the current time is very busy, cause AresPro very little, switch if accept load this moment again, take original just relatively more nervous resources such as wireless channel, just may cause this cell-overload.Otherwise, when CallNumCurrent is very little, showing that interior this sub-district of a period of time T before the current time is very idle, the result after AresPro calculates is very big, and this sub-district just can be taken out idle resources such as wireless channel and be accepted the load handoff request at this moment.MSC has AresPro, just has been equivalent to understand the information in the sub-district of self having jurisdiction over.Switch for load, be equivalent to have cell-of-origin information.This wherein can define a degree, and AresPro surpasses this degree just can accept the load switching, just can not carry out load and switch.
Load is switched also needs to know target cell information, the method that obtains target cell information has two kinds, first method be every sub-district resource quantity directly configuration give MSC or with the neighbouring relations table of sub-district directly configuration give MSC, but this kind method need be made lot of data configuration worker group in the MSC side, work and loaded down with trivial detailsly make mistakes easily, if Access Network side resource changes, need to prove, these variations are broken down as certain carrier frequency plate, perhaps certain base station power-down, perhaps Traffic Channel (Traffic Channel has taken place in the GSM sub-district, be called for short " TCH ") and Separate Dedicated Control Channel (Stand-aloneDedicated Control Channel, abbreviation " SDCCH ") dynamic translation or the like, all need to revise the related protocol interface, support access network resource information dynamically to report MSC, with regard to as described in the prior art shortcoming, cost prohibitive.Therefore the present invention does not adopt this method to obtain target cell information.
Second kind is that the present invention adopts, be that MSC can obtain the sub-district neighbor information by study, though this is because general cell-of-origin MSC side does not have the allocating cell neighbor information, but MSC has learning functionality, and the cell-of-origin and the target cell information that are about in the order of each Access Network initiation handoff request extract and note, through study after a while, MSC just can obtain abundant neighboring BS information, these information specifically comprise the frequency of adjacent area, and whether scrambler has transmit diversity etc.
Load is switched finally to be by the decision of source base station controller and to initiate, and following process is described below with Fig. 2, simplifies for describing, and is assumed to be common MSC situation, and it is similar to stride the MSC situation:
This flow process comprises the two large divisions on the whole.
First part is that source base station controller transmission load handovers request to directly coupled MSC, specifically comprises step 2000 and step 2100 liang sub-steps.
At first,, when a load switching is initiated in the decision of source base station controller,, can carry out blind switching, promptly only from its neighbor cell table, choose a sub-district wantonly as Target cell though do not understand the loading condition of Target cell in step 2000.Base station controller sends load and handovers request to MSC, wherein load handoff request be from the cell-of-origin to Target cell at random, Target cell is a picked at random from the adjacent area of cell-of-origin at random;
Secondly, in step 2100, MSC is according to the adjacent area table of the load handoff request query source sub-district of receiving, if Target cell is not included in the adjacent area table of cell-of-origin at random, then adds at random Target cell to the adjacent area table of cell-of-origin.This is actually the learning process of MSC.
The ensuing second largest part of this flow process, MSC selects best target cell from the adjacent area table of cell-of-origin, and judges whether best target cell can bear new load, if, the load of carrying out from the cell-of-origin to the best target cell is switched, otherwise, refusal load handoff request.Each later step of step 2200 all belongs to this part.
In step 2200, calculate the AresPro of current area by the MSC of Target cell, MSC is to its available resources probability of information acquisition of all sub-districts in the adjacent area table of cell-of-origin, and the sub-district of available resources probability maximum is a best target cell in the adjacent area table of selection cell-of-origin; Here have two kinds of schemes can reach above-mentioned effect:
First kind of scheme is at the adjacent area of the direct source of configuration of MSC sub-district table; The perhaps available resources probability of all sub-districts in the table of the adjacent area of the direct source of configuration of MSC sub-district; The sub-district of available resources probability maximum is a best target cell in the adjacent area table of selection cell-of-origin.The basis of this scheme is exactly the first method of aforementioned acquisition target cell information.
Second kind of scheme at first dynamically set up the adjacent area table of cell-of-origin at MSC; Wherein, MSC dynamically sets up the adjacent area table of cell-of-origin by the message of study base station controller.At statistical information and the configuration information of MSC, calculate the available resources probability subsequently according to all sub-districts in the adjacent area table of cell-of-origin.Wherein, statistical information comprises position update times, sub-district the current number of calls current slot in of sub-district in current slot, configuration information comprises the maximum number of calls of sub-district in the busy time period, available resources probability and position update times are inversely proportional to, and the available resources probability is directly proportional with the difference that the maximum number of calls deducts the current number of calls.That is to say the information of analyzing all sub-districts in the table of adjacent area according to the computing formula of aforementioned AresPro.Selecting the sub-district of available resources probability maximum in the adjacent area table of cell-of-origin at last is best target cell.
In step 2310, owing to judge the value of the local resource probability maximum in the table of adjacent area less than Threshold, so the Access Network that there is no need to be had jurisdiction over to Target cell MSC is again transmitted this request in step 2300.Send refusal load handoff request to the source cell base station controller.Flow process finishes.
Subsequently in step 2400, because the value of judging the local resource probability maximum in the table of adjacent area in step 2300 is less than Threshold, so carry out load switching from the cell-of-origin to the best target cell; In two little stages of concrete branch, the base station controller to best target cell sends handoff request at first; Then the load switching command is sent to the source cell base station controller.
In step 2500, send switching command to subscriber equipment at last by this source cell base station controller.Flow process finishes.
Though by reference some preferred embodiment of the present invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that, can do various changes to it in the form and details, and the spirit and scope of the present invention that do not depart from appended claims and limited.
