GETA is according to Irish B formula, calculates the function of traffic capacity with the number of channel and the percent of call lost.
At first introduced the data service telephone traffic in the present embodiment.Because along with general packet radio service (General Packet Radio Service, GPRS), improve GSM evolution technology (the Enhanced Data rate for GSM Evolution of data rate, EDGE) etc. after data service is carried out in a large number, can produce a very large impact the wireless network utilance, especially the bigger big city of some data traffics has badly influenced the accuracy of obtaining the gsm wireless network utilization.Therefore in the molecule of above-mentioned formula, introduced the actual data equivalence telephone traffic that produces in the system, introduced PDCH static channel number as Systems Theory design data traffic capacity in denominator, dynamically the data service telephone traffic of PDCH channel generation is included in the theoretical traffic capacity of TCH of denominator.
Secondly, introduced the SDCCH telephone traffic.Because on the SDCCH channel, also can finish a series of traffic incidents, comprise: the signaling before the call setup continues, (comprising periodic location update), IMIS are upgraded in the position, and (Integrated Management Information System IMIS) adheres to/separate, short message etc.These call events can produce telephone traffic equally on SDCCH.Simultaneously, when call proceeding, if there is not available SDCCH channel, system substitutes the transmission that the SDCCH channel is finished signaling message with direct distribution T CH channel, and this situation is wasted resource very much.As seen the congested lifting that may cause the TCH telephone traffic of SDCCH.So perfect gsm wireless network utilization obtains also should be included with SDCCH utilization of resources situation.Therefore introduced the actual SDCCH telephone traffic that produces in the system in the molecule of formula, with the theoretical SDCCH design of the traffic model computing system traffic capacity of SDCCH simulation TCH, percent of call lost value and TCH are different certainly in denominator.
Simultaneously, revised the influence of half-rate speech telephone traffic.Because being the full-speed voice telephone traffic, the TCH voice telephone traffic amount of the actual generation of system in the molecule adds total voice telephone traffic amount of half-rate speech telephone traffic, can significantly absorb traffic if enable half rate so in a large number, thereby raised molecule, made the wireless network utilance of obtaining higher.In order to revise this deviation, in the time of can in denominator, calculating Systems Theory voice design telephone traffic, add and open the corresponding telephone traffics of calculating of half rate more.
When simultaneously, having revised system busy and BSC inconsistent problem when busy.Because the period of right time in the system when peak hour of each BSC and system busy is also inequality probably.Inconsistent during with system busy when if the BSC of most of BSC is busy, there is some difference must to cause the wireless network utilance obtained and real network to be loaded.Therefore consider the problem when BSC is busy, molecule is taken as each BSC telephone traffic sum when busy, but not the total traffic when directly going system busy.
Simultaneously, revised the unusual cell telephone traffic amount of the percent of call lost.In GSM network planning design, the sub-district target percent of call lost in city all gets 2% at present, if the actual percent of call lost (containing switching rate) of certain sub-district surpasses 2% in the city, can think that then this sub-district has been in abnormal condition.If there is the actual percent of call lost (containing switching rate) of part sub-district to surpass 2% in the network, then can think system's overload operation, this moment, the offered traffic of system will be greater than the telephone traffic of finishing of system, because the actual percent of call lost (the containing switching rate) lost traffic that lifting brings be can not ignore, and should compensate.Therefore, in algorithm, the actual percent of call lost (containing switching rate) surpassed the actual percent of call lost (containing switching rate) of 2% sub-district and the number of channel and in molecule, replace original sub-district TCH telephone traffic, obtain the offered traffic of this sub-district reality by the telephone traffic of looking into ERL-B and showing to obtain.
Specifically, when mobile Integrated Network Management System when obtaining the BSC duration that the PDCH of each cell configuration takies the whole network when busy from the radio operation maintenance centre, can obtain the PDCH average (duration that PDCH takies/3600) that each sub-district takies, i.e. the data equivalence telephone traffic A of each sub-district when BSC is busy
Pdch, to its data equivalence telephone traffic of suing for peace and to obtain N sub-district in the whole network.
When mobile Integrated Network Management System according to obtaining BSC from the radio operation maintenance centre when busy the whole network during the SDCCH telephone traffic of each sub-district, can obtain the SDCCH telephone traffic A of each sub-district when BSC is busy
SdTo its SDCCH telephone traffic of suing for peace and to obtain N sub-district in the whole network.
When mobile Integrated Network Management System according to obtain BSC each sub-district voice telephone traffic amount the whole network when busy from the radio operation maintenance centre, the actual percent of call lost of each sub-district TCH when the TCH of each cell configuration counts when (containing switching rate), in the whole network in the whole network when BSC is busy, target percent of call lost E all gets 2% when the sub-district in city, if the actual percent of call lost (containing switching rate) that K sub-district arranged in the whole network N sub-district is smaller or equal to 2%, the voice telephone traffic amount of each sub-district when BSC is busy is A so
Tch i E, be exactly that the actual percent of call lost (containing switching rate) is smaller or equal to the voice telephone traffic amount of 2% all sub-districts when BSC is busy with the voice telephone traffic amount addition when BSC is busy of K sub-district; If the actual percent of call lost (containing switching rate) that L sub-district arranged is greater than 2%, just according to Irish B formula, by the GETA function with the TCH number of each cell configuration and the percent of call lost (the containing switching rate) E of reality separately
iCalculating traffic capacity separately, is exactly the actual percent of call lost (containing switching rate) E after the addition
iThe voice telephone traffic amount of L greater than 2% sub-district when BSC is busy replaces original L sub-district TCH telephone traffic, obtains the offered traffic of L sub-district reality.
SDCCH telephone traffic, the actual percent of call lost (containing switching rate) of N sub-district in the equivalent telephone traffic of the data of N sub-district in above-mentioned the whole network that draws, the whole network are sued for peace as the molecule in the formula that obtains wireless network utilance method greater than 2% the voice telephone traffic amount of L sub-district when BSC is busy smaller or equal to 2% voice telephone traffic amount, the actual percent of call lost (containing switching rate) of K sub-district when BSC is busy;
When mobile Integrated Network Management System according to the whole network voice telephone traffic amount A when the radio operation maintenance centre obtains system busy
Tch, the whole network half-rate speech telephone traffic A during system busy
Tch/HSThe time, according to Irish B formula, obtain the Systems Theory voice by the GETA function with the TCH number of N in the whole network each cell configuration of sub-district and target percent of call lost E and design telephone traffic; The whole network half-rate speech telephone traffic A when Systems Theory voice design telephone traffic and system busy
Tch/HSThe whole network voice telephone traffic amount A during with system busy
TchRatio A
Tch/HS/A
TchThe corresponding voice telephone traffic amounts of calculating of half rate are opened more by the system that obtains that multiplies each other.
When mobile Integrated Network Management System when obtaining from the radio operation maintenance centre that the static PDCH of each cell configuration counts the whole network, can obtain static PDCH numbers all in the whole network after the summation and multiply by an Ireland again and obtain Systems Theory data equivalence design telephone traffic.
When mobile Integrated Network Management System when obtaining from the radio operation maintenance centre that the SDCCH of each cell configuration counts the whole network, can be according to Irish B formula, obtain Systems Theory SDCCH design traffic capacity by the GETA function with the SDCCH number and the target percent of call lost E ' of each cell configuration.Specifically, if the SDCCH number of channel of cell configuration is 4 o'clock, SDCCH percent of call lost E ' is 50% of the TCH percent of call lost, promptly 1%; If the SDCCH number of channel of cell configuration is 8 o'clock, SDCCH percent of call lost E ' is 25% of the TCH percent of call lost, promptly 0.5%, then can draw the Systems Theory SDCCH design traffic capacity of each sub-district, and after the summation Systems Theory SDCCH design traffic capacity.
The corresponding voice telephone traffic amounts of calculating with the unlatching half rate of the above-mentioned Systems Theory voice design telephone traffic that draws, Systems Theory data equivalence design telephone traffic, Systems Theory SDCCH are designed the traffic capacity summation as the denominator that obtains in the wireless network utilance method formula more;
The percentage of the ratio of above-mentioned molecule and denominator is gsm wireless network utilization α.
