Description
Technical field
The present invention relates to the communications field, and especially, relate to a kind of SMS terminal call route processing method and system.
Background technology
At present, the concern that the communication value-added service receives day by day increases, and in many value-added services, short message is a part and parcel always.
According to statistics, 2006, the note amount of China surpassed 4,000 hundred million.And the distinguishing feature of short message service is that traffic carrying capacity is big, signaling traffic load is high and it is uneven to distribute.Analyze according to statistics, the traffic carrying capacity of festivals or holidays is at ordinary times several times to tens times, and the impact of festive occasion short message service amount and surge can bring to the SS7 signaling network and surpass several times pressure at ordinary times.Therefore, the festive occasion user often has transmission and receives the sensation that short message is slow, success rate descends, and this is actually the performance of SS7 signaling network under the situation that continues high load capacity.
If such as (the Virtual Mobile Switching Center of virtual mobile switching centre; VMSC) and SP (the Signaling Point of Home Location Register (HLR); Signalling point;), STP (SS7 Signal Transfer Point, Signalling Transfer Point) collapses down at long high load capacity, will cause the paralysis of bulk zone even whole network.
The short message service flow process mainly be divided into Mobile Origination (Mobile Originate, MO) and Mobile Termination (Mobile Terminate, MT) two parts.MO is that the calling subscriber is submitted to short message service center to short message (Short Message Service Center, SMSC), MT is that SMSC is delivered to the called subscriber to short message.Its signaling process can divide following 3 parts:
(1) rises and exhale MO Forward (Request & ACK);
(2) route, SRI (Send Routing Info, Request & ACK);
(3) exhale MT Forward (Request & ACK) eventually;
Wherein, MO Forward (Request & ACK) occurs in the MO process.SRI (Request & ACK) and MT Forward (Request & ACK) occur in the MT course.Suppose that each signaling command all is that (MessageSignal Unit, MSU) bag is accomplished, and therefore can extrapolate to accomplish a short message service and need 6 MSU bags through a Message Signal Unit.
In the short message MT process, because cellphone subscriber's mobility, SMSC when the called subscriber delivers short message, can carry out routing inquiry to HLR through the SRI signaling at every turn.SMSC utilizes SRI can obtain called subscriber's address from HLR, that is, the VMSC number at called subscriber place is delivered to the VMSC that the called subscriber belongs to short message, is delivered to called mobile phone to short message by VMSC.
In fact the zone of each VMSC administration is a very big scope, and therefore, the user need spend a period of time when striding the roaming of VMSC.And most users' position is relatively-stationary in a period of time generally, that is, most users in a period of time residing VMSC can not change.
Though above-mentioned is each simple to the method for HLR inquiry route through the SRI signaling when short message MT, its shortcoming is also obvious, the load of each exactly routing inquiry operation must increasing signaling network.
Yet, the method that can address this problem is not proposed at present as yet.

Embodiment
Method embodiment
In the present embodiment, a kind of SMS terminal call route processing method is provided.
This method comprises: step S102, when the called subscriber sends when eventually exhaling route requests, in local search called subscriber's virtual mobile switching centre route historical information (being designated hereinafter simply as the route historical information); Step S104 judges whether called subscriber's route historical information is effective, if effectively, then uses local route historical information of preserving to deliver; Otherwise at Home Location Register inquiry called subscriber's virtual mobile switching centre routing iinformation (being designated hereinafter simply as routing iinformation), use is delivered from the routing iinformation that the Home Location Register inquiry obtains; And step S106, use the local route historical information of updating route information called subscriber that obtains from the Home Location Register inquiry.
Wherein, this locality among the step S102 is meant the routing iinformation maintenance module, and this module can be embedded in the short message service center at called subscriber place.Exhale the end that the route historical information effectively representes to exhale the end of this transmission of called subscriber route requests and last time to send in the position in stationary phase, and the called subscriber accomplish this of exhaling route requests eventually in same virtual mobile switching centre and send and transmission last time in time interval between the route requests.
Wherein, Representing that the user sends the time period of message stationary phase in the scope of same mobile switching centre, is example with the Spring Festival, from 6 mornings to the junior one of evening at New Year's Eve; Most users stay at home and reunite with one's family; Striding mobile switching centre, to send the possibility of note almost nil, therefore, can be from this time period intercepting 1 hour position stability phase for example as the user.Exhale the end that the route historical information effectively representes to exhale the end of this transmission of called subscriber route requests and last time to send in the position in stationary phase, and the called subscriber accomplish this of exhaling route requests eventually in same virtual mobile switching centre and send and transmission last time in time interval between the route requests.
Here, can also introduce the notion of frequency sending probability.This representation of concept is time cycle stationary phase inside in the position, the probability of short message service center's short-message sending under same user.Suppose that short message service center has sent five short messages to same user altogether, the position stability phase is 1 hour, and article one short message is sent in 9 points; The second short message is sent in 9: 5, and the 3rd short message is sent in 9: 15, and the 4th short message is sent in 9: 20; And the 5th short message is sent in 11 points, so then the second short message belongs to the frequency transmission, first, five short message do not belong to frequency and send; In this case, the frequency sending probability is 60%.
In addition, this method may further include: steps A if called subscriber's route historical information is effective, then increases called subscriber's the position stability phase; If called subscriber's route historical information is invalid, then reduce called subscriber's the position stability phase.
And, in steps A, can called subscriber's route historical information whether effectively add up when repeatedly delivering, and analyze according to algorithm, confirm position recruitment and the decrease of stationary phase.That is to say that if user's route historical information is effective in step S104, then the employed position stability phase is reliable before the explanation; And user's position is metastable; Therefore, can increase the position stability phase through estimation, thereby can further reduce the load of SS7 signaling network.On the contrary; Under user's route historical information is invalid situation; The employed position stability phase is insecure before explaining, therefore need reduce the time span of position stability phase, and anti-locking system thinks still that under the unsettled situation of customer location the user does not carry out route.
Here, the recruitment of position stability phase and decrease are ratio or interim one or more unit interval of position stability of the time span of position stability phase.Here, the unit interval is cycle regular time, for example, can be 5 seconds.And algorithm can comprise: multiple is handled, and multiply by one greater than 1 fixedly multiple with currency during increase, during minimizing with currency divided by one greater than 1 fixed value; Fixed amount is handled, and increases a fixed value during increase, reduces by a fixed value during minimizing.For example, when algorithm is 2 times of processing, during the phase position stability phase multiply by 2, during the phase position stability phase multiply by 1/2 when reducing position stability when increasing position stability; When algorithm is that fixed amount is 1 when handling, recruitment and reduction all are 1 unit interval.
In addition, in above-mentioned steps S104, can further include: obtain the delivery result, judge the called subscriber virtual mobile switching centre of whether moving out; And when judging that the called subscriber moves out virtual mobile switching centre, remove the called subscriber also inquires about the called subscriber again from Home Location Register in the route historical information of this locality routing iinformation.
In above-mentioned processing, through continuous statistics, just can grasp user's movement law to position stability phase of user, thus the information flow-rate that produces can reduce to send SMS message the time.Therefore, can reduce the load of SS7 signaling network in the daily life.
Preferably, can classify in advance (for example, when the user buys portable terminal) to the user group according to user's identity difference, so that the statistics and analysis work of carrying out in the future.
