Referring to the specific embodiment of the base station call balance method of each brief description of the drawings present invention of the invention.For purposes of illustration only, assuming that personal terminal is mobile phone in following retouching in detail is confused.
Fig. 2 shows the schematic flow diagram of the first scheme of the base station call balance method of the present invention.As shown in Fig. 2 starting after the automatic traffic equilibrium function of base station, in the detection BTS services of step S 20 channel busy/idle condition.Such as bright to judge that the base station is in Traffic Channel busy state in step S 30, then system notifies this busy state of base station to corresponding personal terminal in step S 40 so that the personal terminal is no longer attempt to build to the base station
3 000239
Vertical communication link;Otherwise, the Traffic Channel that corresponding personal terminal base station is notified in step S 50 is in idle condition by system, and then personal terminal can be attempted to set up communication using common working method to the base station.After said process, judge whether to close base station automatic traffic equilibrium function in step S 60, if do not closed, system is from abovementioned steps
S 20 restarts to perform;Otherwise, terminate to perform in step S 70 and be confused base station automatic traffic equilibrium function, base station is according to common mode of operation.
One embodiment of this scheme is described below.Before this embodiment is introduced, it is necessary to first simply introduce PHS system control channels operation principles.In PHS systems, there are three class down control channels, respectively broadcast channel(BCH), PCH() and access control channel PCH(SCCH), wherein PCH is used to send called notice, and access control channel is used to give handset allocation Traffic Channel, and the content in broadcast channel is used for the current running status of base station broadcasts system and relevant parameter.Message in broadcast channel is divided into three classes again, respectively radio channel information broadcast message (Radio channel information broadcasting message) system information broadcast message (System information broadcasting message) ^ electrical secondary systems information broadcast message (Second system information broadcasting message).This three classes message is alternately sent in broadcast channel.Wherein in system information broadcast message, there is the special field that a length is 5 bits, referred to as base station information " CS information ", the current type for reporting base stations.5th bit value of the field means that base station is currently that upstate, i.e. mobile phone can select to work under the base station or standby when being 0.It is currently down state to mean base station when this bit value is 1, and mobile phone can not select to work under this base station or standby.
In the present embodiment, it is to utilize " CS information " this bit to realize traffic balance function, and it is combined with BTS service channel occupation status, the busy-idle condition of base station is notified terminal user by broadcast message in time.By taking 7 channel base stations as an example, when base station detect 7 Traffic Channels it is all occupied when, the base station information in the system broadcast message sent later is just set to the unavailable shape in base station
State, the base station is just in the state of " temporary extinction " so for mobile phone, and mobile phone just will not send new link setup to the base station and ask, and also to find an other base station again standby for standby mobile phone under the base station.And when suddenly station detect there is idle channel when, the base station information in the system broadcast message sent later is set to base station upstate again, so the base station is just returned among " sight " of mobile phone again, and mobile phone can send link setup request or standby below this base station to it.
The process for developing this traffic channel equilibrium function in the present inventor also found, in order to save the energy content of battery, extend stand-by time, some mobile phones with holding state only receive the message of PCH, do not receive the message of broadcast channel in the standby state.Only when the broadcast reception in PCH indicates that " Broadcasting reception indication " changes, mobile phone could be notified to collect the content in broadcast channel again.Therefore in the case of this mobile phone with holding state, only changing system broadcast message can not play a part of notifying mobile phone in time.When base station needs to change by the upstate for the notice cellular base station that broadcasts the message, need first to change the broadcast reception in PCH to indicate, system broadcast information is then changed again, so just the change of base station upstate can be notified mobile phone in time.
Fig. 5 shows the schematic diagram of the device corresponding with a kind of the first above-mentioned scheme of base station call balance method of the mat woven of fine bamboo strips of the present invention.In order to illustrate for the sake of simplicity, illustrate only the personal communication access of the present invention in figure(PAS) a part for system, that is, illustrate only a base station 2, and with the personal terminal 5 of the base station 2 associated two.But, it will be understood by those skilled in the art that in same PAS systems, may there is multiple base stations, and each base station can be associated with multiple personal terminal.As shown in figure 5, one is provided with base station 2 notifies device 501 and a recovery device 500, and the notice device 501 also includes receiving message indicating unit 502 and busy state notification unit 503.When base station 2 is in Traffic Channel busy state, receives message indicating unit 502 and change the broadcast reception instruction in the PCH that the base station 2 passes through system control channels to notify the corresponding reception system of personal terminal 5 to broadcast the message.Busy state notification unit 503 changes base
The content for the 2 system information broadcast message for sending personal terminal 5 to by the broadcast channel in system control channels of standing, i.e., by the way that the 5th bit position 1 of the base station information in the system information broadcast message is embedded in the instruction Traffic Channel of base station 2 busy information in the broadcast message.Personal terminal 5 is being received after the broadcast reception sent by reception message indicating unit 502 is indicated from system broadcast channel reception system information broadcast message, so that personal terminal 5 recognizes the heavy traffic state of base station 2, the personal terminal 5 is then set no longer to attempt to set up communication to the base station 2.When base station 2 returns to service condition idle condition from business channel busy state, this idle condition of base station 2 is notified to corresponding personal terminal 5 by recovery device 500, then the personal terminal 5 can be attempted communicate with the base station 2 foundation by common working method.So as to realize base station automatic traffic equilibrium function.
Fig. 3 shows the schematic flow diagram of the second scheme of the base station call balance method of the present invention.As shown in figure 3, after this base station call balance is started, the working condition of base station is detected in S 110 first.Then Bu Sudden S 120 judge whether the base station is in Traffic Channel busy state.If answer is " being ", the control information sent from system control channels to personal terminal is all shielded in step S 130, then the personal terminal is no longer attempted to set up communication to the base station.If answer is " no ", judge that the base station is in Traffic Channel idle condition, system sends control message to personal terminal in usual way in the control channels of step S 140.Complete after aforesaid operations, judge whether the traffic balance function closes in step S 150.If do not closed, return to step S 110 continues to repeat step S 110 to S 150 operation;Otherwise, traffic balance function is closed in base station, using common mode of operation.
Retouch in detail now and be fascinated by a specific embodiment for stating two kinds of schemes of the mat woven of fine bamboo strips.Herein by taking 7 channel base stations as an example.As can see from Figure 3, second scheme is more direct, when base station detect 7 Traffic Channels it is all occupied when, just the content of all bits in later control channel is changed to entirely " send; the information sent on the base station control channel can not be parsed completely so for mobile phone, its effect is equivalent to the base station " temporarily to disappear
Lose ", i.e., all control information that the base station is sent to it to mobile phone " shielding ", then mobile phone will not be to the new link setup request of base station transmission, also can not be standby under the base station, it is necessary to find other base stations.And when base station detects channel and reverts to idle condition, then correct control channel information is resend, so base station is just returned among " sight " of mobile phone again, and mobile phone can send link setup request or standby under the base station to it.
Fig. 6 shows the schematic diagram of the device corresponding with two kinds of schemes of the above-mentioned mat woven of fine bamboo strips of the base station call balance method of the present invention.Structure identical part in the structure of the figure with Fig. 5 is presented with like reference characters, and will not be repeated here.As illustrated, being provided with recovery device 500 and control information screening arrangement 601 in base station 2.When base station 2 is in Traffic Channel busy state, the control message screening arrangement 601 is by making all control information shield the personal terminal 5 all bit positions " 1 " of the information sent via system control channels to corresponding personal terminal 5, so that the personal terminal 5 is not attempted to set up communication to the base station 2 in Traffic Channel busy state.When base station 2 returns to service condition idle condition from business channel busy state, recovery device 500 make base station 2 can by common working method to corresponding personal terminal 5 send control information, then the personal terminal 5 can by common working method attempt with the base station 2 foundation communicate.So as to realize base station automatic traffic equilibrium function.
Fig. 4 shows the schematic flow diagram for the method that base station automatic traffic equilibrium function is realized with reference to above two scheme.As shown in figure 4, personal communication access system(PAS) Bu Sudden S 210 first judge whether to start base station automatic traffic equilibrium function.If not starting the function, common mode of operation is pressed in base station.If starting the function, Bu Sudden S 220 determine whether to start above-mentioned any scheme.If starting a kind of scheme of the mat woven of fine bamboo strips, above-mentioned the first scheme as shown in Figure 2 is performed.If starting two kinds of schemes of the mat woven of fine bamboo strips, above-mentioned second scheme as shown in Figure 3 is performed.If judging not start base station automatic traffic equilibrium function in step S 210, continue to press common mode of operation in the base stations of step S 230.
T N2003/000239
Illustrate a specific embodiment of scheme described in Fig. 4 below.
In order to realize that the automatic traffic of base station balances control function, several parameters can be increased newly in the control software of base station, by the adjustment to these parameters, the traffic balance between base station can be effectively realized.Xian Fen Do are described as follows to each parameter:
Parameter one:Functional switch
This parameter is used to determine whether base station opens traffic automatic balance function.For example it could dictate that, the parameter value is set to 01, and base station will perform traffic balance function according to scheme one;The parameter is set to 02, and base station will perform traffic balance function according to scheme two;00 or other values are set to, base station will close traffic balance function.When the parameter is set to 01 or 02, following four parameter will be functioned to.
Parameter two:Base station busy state activation Gang values
When automatic traffic equilibrium function switch in base station is unlocked, base station idle channel number will be automatically into busy state when less than the threshold value, and now base station will be by changing system broadcast information message(Scheme one;) or directly destruction control channel in content(Scheme two), notify that the mobile phone base station is temporarily unavailable, such mobile phone will be unable to the base station set up it is new contact or standby under the base station, so as to avoid the further increase of this numerous ^ base station call, and force other base stations of remaining traffic direction.It is emphasized that the mobile phone conversed with this base station is unaffected.The unit that this parameter is used for station spare idle channel number, for example, for 7 channel base stations, the configuration scope of the parameter is 00-06, for the group control base station of 15 channels, the configuration scope of the parameter is 00-0E (14 idle channels).It is recommended that default parameter value be 00, i.e., when all channels in base station are occupied full entirely, just into busy state.
Parameter three:Base station idle condition activation threshold
Equally, opened when base station automatic traffic equilibrium function is switched, base station idle channel number will enter idle condition, i.e. normal operating conditions when exceeding the threshold value from busy state, and now system broadcast information is changed in base station again(Scheme one)Or recover to send control information via control channel(Scheme two), notify the mobile phone base station is reverted to available, then hand
Machine can carry out normally associate or standby under the base station with the base station.This means when the traffic busy state of base station obtains Slow solutions, base station can recover normal condition, until entering busy state next time.The unit of this parameter is equally determined by the idle channel of station spare, for example, for 7 channel base stations, the configuration scope of the parameter is 01-07, for group control base station, the configuration scope of the parameter is 01-0F (15 idle channels).It is proposed that default parameter be 01, i.e., when base station occur an idle channel when, base station will enter idle condition by busy state.It should be noted that the value of this parameter, which should be more than base station busy state, activates pavilion value, logical miss otherwise will occurs.
Four/parameter of parameter five:Base station is busy/the idle condition retention time
In order to prevent base station frequent switching between busy state and idle condition, in systems be provided with base station it is busy/idle condition retention time parameter.For example, when base station is in busy state, not idle condition is just immediately switched to when meeting idle condition activation condition, and be to continue with being kept for the regular hour in busy state, during this period of time, if base station detects channel occupancy number and meets idle condition activation condition all the time, base station just enters idle condition.If in this period, base station detects letter occupancy number and is unsatisfactory for idle condition activation condition, then base station continues to keep busy state, idle condition activation condition is reached again until detecting channel occupancy number next time, timing is restarted in base station, if can meet the switching of idle condition activation condition ability generating state always within the retention time.
Therefore, it is noted that, alleged BTS service channel clear refers to that the base station has the idle business channel for being more than or equal to base station idle condition activation threshold in quantity within the idle condition retention time in the present invention;And BTS service channel busy state refers to that the base station has the idle business channel for being less than or equal to base station busy state activation threshold in quantity within the busy state retention time.
Fig. 8 schematically illustrate a selected the role of this pair of states switching retention time of parameter four/five, it is assumed here that the retention time of the two states is disposed as 2 seconds.It is not difficult to find out, if being not provided with the state switching retention time, base station will be toggled busy between idle condition, very frequently, as shown in curve above in Fig. 8.And work as and be provided with this
After two state switching retention times, curve becomes relative smooth, as shown in a curve below in Fig. 8, i.e. base station, which only meets in condition and generating state is just understood in the case of relatively stablizing, to be changed.Especially for PHS systems, when being registered due to mobile telephone registration also can of short duration occupancy base station Traffic Channel, in order to prevent because registration causes base station state to change, it is necessary to set this two parameters.It is recommended here that default parameter value be 5 seconds.
Represented in the present invention with the content of a byte above-mentioned base station it is busy/the idle condition retention time, so two retention times can all be set in the range of 0-255 seconds.
From the point of view of the result of practical application, the effect that two schemes reach is substantially suitable, and latter scheme has more preferable handset compatibility(The mobile phone of particular type is without the situation for correctly handling " CS information " change in accordance with the regulation of PHS agreements completely, therefore the first scheme has the problem of some are compatible at this stage).Therefore, although above two scheme can realize automatic traffic equilibrium function in base station in PAS systems, but in the situation higher to mobile phone compliance, generally be proposed with second scheme.
Fig. 7 shows the schematic diagram of the device corresponding with a kind of and second scheme method of the above-mentioned mat woven of fine bamboo strips of the base station call balance method with reference to the present invention.The structure of the figure is similar with Fig. 5 and Fig. 6, and wherein identical part is presented with like reference characters, will not be repeated here.As shown in fig. 7, being provided with recovery device 500 and function selection device 701 in base station 2.Function selection device 701 also includes parameter set unit 702, base station operation state detection unit 703, parameter detecting unit 704 and base station automatic traffic equilibrium function execution unit 705.Parameter set unit 702 is used to set traffic balance function on parameter, the first traffic balance functional parameter, the traffic equilibrium function parameter of the mat woven of fine bamboo strips two for the work of control base station 2.Base station operation state detection unit 703 is used for the traffic channel state for detecting base station 2, if the base station 2 is in Traffic Channel idle condition, makes the base station 2 according to common mode of operation.If detecting base station 2 is in Traffic Channel busy state, system makes traffic equilibrium function start-up parameter, the first traffic balance functional parameter, the traffic equilibrium function parameter of the mat woven of fine bamboo strips two of the detection of parameter detecting unit 704 base station.When the traffic balance function on parameter is not enable value, make base station 2 according to usual working method
Work, base station automatic traffic equilibrium function is not performed;When the traffic balance function on parameter is enable value, while when any one in the traffic balance functional parameter of the mat woven of fine bamboo strips one and the second traffic balance functional parameter is enable value, then performing corresponding base station automatic traffic equilibrium function.Specifically, when the traffic equilibrium function start-up parameter detected by the parameter detecting unit 704 and the first traffic balance functional parameter are enable value, base station automatic traffic equilibrium function execution unit 705 performs base station call balance method as shown in Figure 2;When the traffic equilibrium function parameter of traffic equilibrium function start-up parameter and the mat woven of fine bamboo strips two detected by parameter detection equipment 704 is enable value, the base station automatic traffic equilibrium function execution unit 705 performs base station call balance method as shown in Figure 3 above.For example, traffic balance function on parameter can be set into 00 or other values, the enable value of the traffic balance functional parameter of the mat woven of fine bamboo strips one is set to 01, the enable value of the second traffic balance functional parameter is set to 02.Certainly, it will be understood by those skilled in the art that the setting of above-mentioned parameter value can also have many kinds may.
Although the base station automatic traffic equilibrium function of the present invention is preferably realized by related control software.But it is also possible to be realized with the above-mentioned device with reference to described in Fig. 5-7.Moreover, those skilled in the art can be easy to think other devices for being used to realize this base station automatic traffic equilibrium function.
After the exploitation of this function is completed, its New function as base station has been carried out on-the-spot test by the present inventor, to verify its validity and practicality.Fig. 9 and Figure 10 are using the telephone traffic and blocking rate contrast schematic diagram before and after the base station automatic traffic equilibrium function of the present invention respectively in PAS systems.
Here by taking 7 channel base stations as an example, after traffic balance function is opened, set quadrinomial parameter is respectively:
Base station busy state activation threshold:1 free timeslot
Base station idle condition activation threshold:2 free timeslots
Base station is busy/the idle condition retention time:5 seconds
Be not difficult to find out from Fig. 9 and Figure 10, employ traffic balance function base station it is busy
When telephone traffic slightly have reduction than the base station without use traffic balance function, about 1 Ireland left and right, but remain to maintain 4Erl or so level of relatively doing(7 channel base stations can about provide 3.5Erl telephone traffic in the case of blocking rate is 5%), this illustrates that the traffic of the base station has been measured and efficiently controlled that the part telephone traffic beyond base station ability to bear is effectively shunted away, realizes the purpose of traffic balance.
And on the other hand, using the busy blocking rate of traffic balance function base station well below the base station for not using traffic balance function, control substantially 5% or so, and the base station busy blocking rate for not opening the function is averagely about 25%.Expected purpose is also can reach in this, and this improvement will be helpful to improve the jointing-success-rate of calling and the speed that continues.
Present inventor is also tested to 15 channel Group controls base station, has also obtained relatively satisfactory result.Compatibility test additionally has been carried out to the various type of cell phone that presently, there are, has not had obvious side effect when fact proved that this functionality is in particular by scheme two.Figure 11-13 is the result obtained by the above-mentioned test of present inventor's progress.Figure 11 is its telephone traffic situation contrast before and after the base station automatic traffic equilibrium function for enabling the present invention;Figure 12 is blocking rate situation contrast before and after the base station automatic traffic equilibrium function for enabling the present invention;Figure 13 is to enable the compatibility test result carried out after base station automatic traffic equilibrium function of the invention to various model mobile phones.It is bright according to the effect of these tests, it can be deduced that traffic balance function helps to provide the overall performance of PAS systems between conclusion, this base station of the invention., can be with the traffic between active balance base station, telephone traffic from busy base station by introducing base station automatic traffic equilibrium function(Such as it is located at the high-power resistance control base station of busy section of town)It is diverted to idle base station(Such as the undesirable high-power base station of installation site or the small-power base station of mixed networking), the blocking rate of busy base station is on the one hand reduced, improves and continues speed and shorten connecting time, on the other hand improve the utilization rate of other BTS service channels, make the investment of user obtain most adequately and reasonably utilizing, reduce cost.
