Embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
The orbit of the vehicles generally is the fixed line that is connected to form by at least two above websites, and the vehicles are stopped at website, to make things convenient for passenger's vehicles up and down.The vehicles remain static when website is stopped, standing-meeting causes vehicles user to change about the passenger at this moment, and the vehicles are in case operation, generally no longer allow the passenger arbitrarily about, can think that passenger's quantity is fixed in the vehicles of running status.In addition, when the vehicles are stopped website, not only the passenger changes greatly, and the reason that need get in touch with the external world owing to the passenger of the vehicles up and down, general also is the busiest period of user's communication, between mobile base station and extraneous fixed base stations a large amount of switchings may take place simultaneously, so the telephone traffic of this moment is generally higher.For these reasons, speech quality when guaranteeing that website is stopped, and the bandwidth resources that practice every conceivable frugality, the main thought of the embodiment of the invention is: the motion state according to the vehicles is adjusted the bandwidth of the external interface of mobile base station, when the vehicles pull in, telephone traffic is big, and the bandwidth of adjusting the external interface of mobile base station is maximum external interface bandwidth; When the vehicles started, passenger's basic fixed can be adjusted suitable external interface bandwidth according to actual user's number, telephone traffic etc.
Fig. 1 is the schematic flow sheet of interface of mobile base station bandwidth method of adjustment first embodiment of the present invention, and as shown in Figure 1, this interface of mobile base station bandwidth method of adjustment may further comprise the steps:
Step 101, obtain the motion state of the vehicles of carrying mobile base station.
The motion state of the vehicles of carrying mobile base station may be inactive state or running status.The method that detects the motion state of the vehicles in the actual application has multiple, for example:
Method one, the described vehicles present located of detection geographical position, if described present located geographical position is identical with the residing geographical position of last detection, the motion state of judging the described vehicles is an inactive state, otherwise judges that the motion state of the described vehicles is a running status.
In the mobile base station, can dispose a GPS positioner and mobile judge module in advance, mobile judge module regularly obtains the coordinate in current geographical position to the GPS positioner, if the coordinate change in the coordinate in this detected geographical position and last detected geographical position, can judge that then the vehicles are in running status, the coordinate in this detected geographical position is identical with the coordinate in last detected geographical position, can judge that the vehicles remain static.
Method two, obtain the operational factor in the power set of the described vehicles, determine that according to described operational factor the motion state of the described vehicles is inactive state or running status.
The mobile base station can be communicated with the power set of the vehicles and be connected, the speed information of the power set that obtain by mobile judge module, parameters such as switch door information can judge comprehensively that the vehicles are in running status or remain static.For example: when the speed of a motor vehicle is 0, and be inactive state during door opening state, otherwise be motion state.
Further,, avoid the influence of state waggling in order to obtain vehicles actual motion state more exactly, can be to come the final motion state of integrated decision-making more than motion state once.As: mobile judge module continuous quadratic is judged as motion state and just finally is defined as motion state; Mobile judge module continuous quadratic is judged as inactive state and just finally is defined as inactive state.
Step 102, according to the motion state of the described vehicles, adjust the bandwidth of the external interface of described mobile base station.
When the motion state of the vehicles that carry the mobile base station was inactive state, for example: the vehicles pulled in, and the bandwidth that can adjust the external interface of mobile base station is the maximum interface bandwidth that allows, speech quality and switching demand when stopping to satisfy website; And when the motion state of the vehicles of mobile base station is running status, then can the bandwidth of the external interface of mobile base station be adjusted, with the conserve bandwidth resource according to number of users, the telephone traffic of reality.
Present embodiment is rationally adjusted the bandwidth of the external interface of mobile base station according to the motion state of the vehicles of carrying mobile base station, can reduce the bandwidth waste of mobile base station external interface, has improved bandwidth utilization, has saved cost of transportation.
Fig. 2 is the schematic flow sheet of interface of mobile base station bandwidth method of adjustment second embodiment of the present invention, and as shown in Figure 2, on the basis of interface of mobile base station bandwidth method of adjustment first embodiment of the present invention, step 102 specifically can comprise following arbitrary step:
Step 201, if the motion state of the described vehicles is an inactive state, increase the bandwidth of the external interface of described mobile base station;
When the motion state of the vehicles be inactive state for example: when pulling in, telephone traffic is big, required bandwidth is low in the time of may be than motion state, therefore, can increase the bandwidth of the external interface of mobile base station, the method for increase bandwidth has multiple, for example: can set in advance a bandwidth added value, when pulling in, the bandwidth of the external interface of mobile base station is increased a bandwidth added value on the basis of original bandwidth.
The bandwidth that also can adjust the external interface of described mobile base station is the maximum interface bandwidth that allows.Particularly, the mobile base station can allow the interface bandwidth application to set up the external interface bandwidth that new link mode is adjusted described mobile base station according to maximum by discharging original communication link again.Also can be by carrying out the mode that the end-to-end link bandwidth is consulted with the mobile base station controller, under the condition that keeps original communication link not discharge, the external interface bandwidth that on-the-fly modifies described mobile base station is the maximum interface bandwidth that allows.
Step 202, if the motion state of the described vehicles is a running status, according to the traffic model data of the current described mobile base station that counts on, adjust the bandwidth of the external interface of described mobile base station.
Wherein, the mode of the bandwidth of the external interface of adjustment mobile base station can comprise: coarse adjustment and fine setting.Coarse adjustment is when the motion state of the vehicles is running status, maximum with the bandwidth of mobile base station external interface during from inactive state allows interface bandwidth to adjust to the required interface bandwidth of actual traffic model data, and the method for fine setting is: according to some telephone traffic index in the running bandwidth of the external interface of mobile base station is carried out trickle adjustment.
In addition, step 201 also can be according to different motion states in conjunction with execution with step 202.
Present embodiment is according to the motion state of the vehicles of carrying mobile base station, and the traffic model data of this mobile base station of arriving of actual count, bandwidth to the external interface of mobile base station is adjusted, can reduce the bandwidth waste of mobile base station external interface, improve bandwidth utilization, save cost of transportation.
Fig. 3 is the schematic flow sheet of interface of mobile base station bandwidth method of adjustment the 3rd embodiment of the present invention, as shown in Figure 3, on the basis of first and second embodiment of interface of mobile base station bandwidth method of adjustment of the present invention, carry out in the process of coarse adjustment in the bandwidth to the external interface of mobile base station, step 202 specifically can comprise:
The traffic model data of cycle statistics mobile base station system, the unit in described cycle can be minute, hour, day, week, month etc.Usually, for the common long-distance vehicles, can be hour being that unit adds up.Described traffic model data include but not limited to: number of users, busy hour calling attempt (BusyHour Call Attempts; Be called for short: BHCA), telephone traffic Ireland (erl), external interface peak flow, external interface flow mean value, call successful rate/call failure rate etc.
Statistical module can be deployed on the mobile base station in advance, also can be deployed on the external equipment, and on the base station controller equipment as the mobile base station, base station controller need be added up respectively at each mobile base station.The startup of statistics can be to add up according to certain fixed cycle, as adding up once every one hour; Also can be to trigger when inactive state becomes running status at the vehicles to start statistics, to satisfy better promptness.If when inactive state becomes running status, trigger the startup statistics at the vehicles, then need design interface between mobile judge module and the statistical module, start statistics by mobile judge module by the message informing statistical module.
The method of statistics number of users can be to insert message according to user terminal to add up, as registration message.In various cellular radio communication systems, all there is a kind of timing enrollment mechanism.For example: in cdma system, general regularly cycle register is 30 minutes, and in hour measurement period, all terminals all can be registered once at least.Since each user user ID for example: international mobile subscriber identity (international mobile subscriber identity; Be called for short: IMSI) or Electronic Serial Number (Electronic Serial Number; Be called for short: ESN) inconsistent, statistics different user sign number is current total number of users.
Below introduce the algorithm that a kind of statistical module is deployed in the statistics number of users on the mobile base station:
At first, in the number of users statistical module, allocate a blocks of data memory block in advance, be used to store the user ID that inserts the user.Before the statistics number of users, at first insert and obtain the user ID that inserts the user the message, then according to described user ID search data memory block from the user.When this user ID is not preserved in the data storage area, illustrate that this access user is a new user, then in the data storage area, store the user ID that this inserts the user, and the number of users of this mobile base station is added " 1 ".When a user ID was preserved in the data storage area, the access user that this user ID correspondence is described was an existing subscriber.
In addition, number of users statistical module timing scan data storage area, when an existing subscriber in finding the data storage area does not insert mobile base station system again in a setting-up time, for example an existing subscriber did not send any message to mobile base station system in two hours, then can be with this existing subscriber's of storage user ID deletion, and the number of users of this mobile base station subtracted " 1 ".
According to the traffic model data of the current mobile base station that counts on, can determine the bandwidth of the external interface that the mobile base station is required.For example: the maximum permission interface bandwidth of supposing the mobile base station is to support 1000 user's voice service call demands.But if the vehicles have only 200 users at present, then current actual user's number of counting on of mobile base station has only 200 users, and then the mobile base station can be according to 200 user's voice call demand application corresponding bandwidth.Shen Qing bandwidth not only can satisfy present all user's voice conversation demands in the mobile base station substantially like this, and has reduced by 80% bandwidth application than the maximum interface bandwidth that allows.
In addition, the telephone traffic that can also arrive in conjunction with the mobile base station actual count is calculated the bandwidth of the required external interface in mobile base station according to telephone traffic, is the external interface application corresponding bandwidth of mobile base station.
The external interface bandwidth that new link mode is adjusted described mobile base station can be set up according to the bandwidth application of required external interface again by discharging original communication link in the mobile base station after the bandwidth of having determined required external interface.Also can under the condition that keeps original communication link not discharge, on-the-fly modify the external interface bandwidth of described mobile base station by carrying out the mode that the end-to-end link bandwidth is consulted with the mobile base station controller.
Present embodiment is according to the motion state of the vehicles of carrying mobile base station, and the traffic model data of this mobile base station of arriving of actual count, bandwidth to the external interface of mobile base station is carried out coarse adjustment, can reduce the bandwidth waste of mobile base station external interface, improve bandwidth utilization, save cost of transportation.
Fig. 4 is the schematic flow sheet of interface of mobile base station bandwidth method of adjustment the 4th embodiment of the present invention, as shown in Figure 4, on the basis of interface of mobile base station bandwidth method of adjustment first, second, third embodiment of the present invention, in the process that the bandwidth of the external interface of mobile base station is finely tuned, step 202 specifically can comprise:
That wherein, describes in the statistical of various traffic model data and the step 301 is identical.
Particularly, can obtain the bandwidth resources tensity of the external interface of described mobile base station earlier according to the traffic model data of described mobile base station; According to the bandwidth resources tensity, determine the bandwidth adjustment amount of the external interface that described mobile base station is required then.If the bandwidth resources tensity of the external interface of described mobile base station, is then determined the bandwidth of bandwidth adjustment amount for needing to increase of the external interface of described mobile base station greater than setting threshold; If the bandwidth resources tensity of the external interface of described mobile base station, is then determined the bandwidth of bandwidth adjustment amount for needing to reduce of the external interface of described mobile base station less than setting threshold.
Wherein, the bandwidth resources tensity of the external interface of mobile base station generally can be defined as follows:
The external interface bandwidth of bandwidth resources tensity=external interface peak flow/base station application; Or
The bandwidth resources tensity=because the call failure rate that the interface band width resource deficiency causes.
In running, statistics external interface peak flow can be monitored and in real time because the call failure rate that causes of interface band width resource deficiency in the mobile base station, and calculates the resource tensity of external interface bandwidth.The highest external interface bandwidth resources tensity can be write down in the mobile base station.
In the mobile base station, preestablish a threshold value, when the bandwidth resources tensity of the highest external interface of mobile base station record during greater than setting threshold, represent that the external interface bandwidth ratio of distributing at present described mobile base station is nervous, be not enough to support present mobile base station to cover user's talk business demand down, then need to increase the external interface bandwidth of mobile base station, the bandwidth adjustment amount of the external interface that described mobile base station is required is the bandwidth that the bandwidth based on present external interface need increase.When the bandwidth resources tensity of the highest external interface of mobile base station record during less than setting threshold, represent that the external interface bandwidth ratio of distributing at present described mobile base station is well-to-do, to support present mobile base station to cover user's talk business demand down, at this moment, the bandwidth adjustment amount of the required external interface in mobile base station is the bandwidth that the bandwidth based on present external interface need reduce.Wherein, the bandwidth adjustment amount can be the bandwidth of a fixed amount, also can change based on certain rule, as: adjusting the Time Bandwidth adjustment amount for the first time is N, and adjusting the Time Bandwidth adjustment amount for the second time is 2N, and adjusting the Time Bandwidth adjustment amount for the third time is 3N.
The bandwidth of the external interface that described mobile base station is required is the bandwidth adjustment amount of the required external interface in described mobile base station and the external interface bandwidth sum of current described mobile base station.The external interface bandwidth that new link mode is adjusted described mobile base station can be set up according to the bandwidth application of required external interface again by discharging original communication link in the mobile base station after the bandwidth of having determined required external interface.Also can under the condition that keeps original communication link not discharge, on-the-fly modify the external interface bandwidth of described mobile base station by carrying out the mode that the end-to-end link bandwidth is consulted with the mobile base station controller.
For existing ongoing conversation is not impacted, the idle period when adjustment can be chosen in a nothing business carries out, but the delay that may cause interface bandwidth to adjust.Postpone for fear of adjusting, and guarantee that the bandwidth adjustment does not impact existing business, can the passage of the interface of original application not influenced, newly-increased bandwidth adjustment amount realizes that in the mode of applying for a new passage mobile base station is born the telephone traffic of external interface jointly by a plurality of interface channels.The interface channel of the external interface bandwidth that will apply for first in the present embodiment is called the main channel, and the new tunnel that increases in the trim process is called from passage, can will for example be numbered from passage: first from passage, second from passage etc.When distribution service, can stipulate: if there are idle bandwidth resources the main channel, professional priority allocation is to the main channel, if the main channel does not have the idle bandwidth resource, then priority allocation to the first is distributed by the numbering size successively from passage.Thereby the business that can guarantee system is concentrated on required several passages.Correspondingly, if exist idlely from passage, can carry out timing from passage to the free time and detect, if above certain hour, certain is in idle condition from passage always, then can discharge this from passage.In general, in the running,, should not be released even the main channel is idle yet.
Every adjustment once with the highest external interface bandwidth resources tensity zero clearing of record, is used so that adjust next time.
In addition, the coarse adjustment in the foregoing description and two kinds of adjustment modes of fine setting can be used in combination.For example: when the vehicles start, carry out a coarse adjustment, then in the follow-up operation process, finely tune in real time according to telephone traffic information of reality etc.; Perhaps, the actual user's number according to statistics carries out a coarse adjustment in a period of time when the vehicles start, and once finely tunes according to the out of Memory that counts on during this period of time at once after coarse adjustment is finished, and in the follow-up operation process, finely tunes in real time.Coarse adjustment and fine setting reflect actual telephone traffic demand more accurately in conjunction with the system that can further guarantee, make the external interface bandwidth more accurate, and efficiency of bandwidth use is higher.
Present embodiment is according to the motion state of the vehicles of carrying mobile base station, and the actual traffic model data of using this mobile base station, bandwidth to the external interface of mobile base station is finely tuned and coarse adjustment, can reduce the bandwidth waste of mobile base station external interface, improve bandwidth utilization, save cost of transportation.
