Abstract

This application relates to a method and apparatus for coupling an analyte supply, such as a biomolecule separator, to an electrodynamic droplet processor. In one embodiment the biomolecule separator is a capillary liquid chromatography column and the droplet processor includes an droplet generator and an electrodynamic balance. The biomolecule separator and the droplet processor may be fluidly coupled to provide a continuous supply of analyte for analysis. The droplets may be controllably ejected from the electrodynamic balance and deposited on a target substrate for use in detecting the analyte by mass spectrometry, such as MALDI time of flight mass spectrometry. Prior to deposition, each of the droplets is levitated in the electrodynamic balance for a period sufficient to enable evaporation of volatile solvents present in the droplet solution, thereby increasing the analyte concentration in the droplet. The solution may include a MALDI liquid matrix and the target substrate may be a MALDI plate. In one embodiment, the method involves depositing a succession of discrete droplets on the target substrate to form one or more microspots having a high density of analytes. The microspots are then irradiated and the ions produced are analyzed by mass spectrometry. The invention improves the sensitivity of analyte detection while consuming a comparatively small volume of test solution.

Background of invention

Technical field

Present invention relates in general to the international roaming user.More particularly, the present invention relates to control from the international roaming user's communications.

Common carrier wave mobile communication system is deployed in global nearly all country by different companies and Virtual network operator.A lot of these Virtual network operators to they travel abroad user (or roamer) and go sight-seeing their area and use the visitor of their external mobile phone that international roaming is provided.The providing of this service makes public mobile network user can use their mobile phone under the network beyond themselves the public mobile network, for example those users network in the zone beyond the coverage of customized network usually.Past in recent years in because the price pressure that competition strengthens and brings thereupon, Virtual network operator is to the income continuous decrease from the local user.On the other hand, in the same period in because the local market mobile infiltration of being on the increase and the increase of tourism, from roamer's income sustainable growth.Various Virtual network operator is preferred mutual bilateral roaming agreement (affiliate), and this bilateral roaming agreement comprises more favourable wandering fee than non-Partner operator.Therefore, " recommendation " visited network is that those are worked as the roamer and travel to when exceeding the local network overlay area, and local network is recommended the network of its departure roamer registration.Non-partner network is " not recommending ".

If roamer's roaming under (or affiliate) network of the recommendation of their local mobile operator, Virtual network operator can be to their maximum revenue, and the roamer can obtain more attracting wandering fee and service.When the user when HPMN roams into visited network, based on various standard, they can roam into one, two or more VPMN, wherein once roam into one.These VPMN also can comprise the VPMN network of " not recommending ".In some cases, in addition when the VPMN network be " not recommending " for the HPMN network, this VPMN network obtains from the immigration of HPMN roaming.This may be because the non-covering of " recommendation " network or the manual selection of inbound roamer.This also may be because the distribution of the communication redirection (TR) (or roaming steering (SoR)) of HPMN causes.Therefore, still registration under the network of " not recommending " of the roamer of HPMN.Sometimes HPMN operator can utilize the communication redirection technology control the roamer the country in the VPMN network between distribute, like this, " recommendation " VPMN network will obtain the HPMN roaming communication of significant proportion, and " not recommending " VPMN network will obtain the roaming communication of low ratio.Those communication redirection technology of being used by HPMN operator can be deprived the immigration roaming income of the Virtual network operator of not recommending.Sometimes, these VPMN operators that deprived income might have partnership relation with HPMN, and even might be " recommendation " VPMN.Further, based on refusal make mistakes, the overtime or communication redirection ended produced network error information to the wave point of cell phone.These generations that make mistakes force cell phone to start a plurality of registrations once more and attempt.This can cause the network interface overload between HPMN and the VPMN.

Exist in a country under the situation more than two VPMN, the wireless coverage of each operator in these VPMN operators just becomes the factor that the preference between them is selected.Yet therefore operator reduces the importance as the wireless coverage of selection factor at the network coverage that constantly strengthens them.Further, some competition and VPMN network " not recommending " has also been disposed communication redirection mechanism in their terminal, and purpose is to leak out their network by the prevention inbound roamer, and keeps inbound roamer.Even when mobile phone owing to any reason (when for example the SIM network directory has produced the failure of registering under recommendation network) to the VPMN network registration, the control of abandoning for any VPMN Virtual network operator the user is very disadvantageous.

(stop the TR system) in the middle of the application that proposes before, described a kind of scheme, this scheme increases the possibility that inbound roamer is successfully registered when one of the HPMN that is the recommendation of VPMN just adopts TR (perhaps SoR) under VPMN.When obtaining, this prevention TR system arranged aspect the inbound roamer of successfully under VPMN, registering the time spent, in case when the user had registered, this system was not at the problem that keeps inbound roamer under VPMN.Present existing feasible program realizes by more wireless coverage and more signaling intensity.For the network of new laying, improving these can spended time.Even, still can there be tiny blind spot, power control, signaling interference, the multipath of signaling and the problem of the coverage that capture-effect causes owing to dynamic environment produces for ripe network.According to observation, the inbound roamer of a country between competition network one day at least alternately 3 to 10 times.

Because above-mentioned one or more problems of mentioning, in the communication redirection field of inbound roamer, need keep inbound roamer, wherein this inbound roamer is the inbound roamer of once registering under VPMN operator, now self just attempt, perhaps be forced to attempt under other VPMN operator, to set up new registration procedure.

The present invention also provides a kind of system that is controlled at the communication of the immigration roaming mobile stations between first visit public mobile network (VPMN), the 2nd VPMN and the local public mobile network (HPMN).This system comprises detecting unit, when described detecting unit one is received from the first registration cancellation message of the one or more registrations cancellation message of HPMN at a described VPMN place, just detects may the changing of registration of described immigration roaming mobile stations.This system further comprises redirected unit, after described one or more registration cancellation message of receiving from described HPMN, by one or more registration messages are sent to described HPMN from a described VPMN, described redirected unit is just attempted described communication redirection is back to a VPMN.For each registration of receiving cancellation message, one or more registration messages are sent out in (T0) at interval at first Preset Time, are registered as the transaction of success up to a registration message.Further, for one or more registration cancellation message of receiving in the current trial that described immigration roaming mobile stations is redirected to a described VPMN, described one or more registration messages are sent out in second Preset Time interval (T1) and/or under the threshold number of setting up new registration procedure at least.

Following description provides concrete details, carries out comprehensively can understanding and enforceable description with the various different embodiment to inbound traffic redirection system (ITRS).Yet, it will be apparent to one skilled in the art that the ITRS system can not implemented in having the situation of these details.In other cases, the 26S Proteasome Structure and Function of knowing at length do not show or describes, to avoid that unnecessary desalination is carried out in the description of the embodiment of ITRS system.Here the title that provides is as just facility, and do not influence the scope of invention or the implication of opinion.

Carry out the environment of ITR

Fig. 1 has shown according to specific embodiments of the invention, the environment 100 that inbound traffic redirection system (ITRS) scheme is performed.Environment 100 comprises a VPMN102, the 2nd VPMN104 and the 3rd VPMN106.Each VPMN has the inbound roamer of oneself, and in the middle of typical situation, (for example do not set the VPMN preference) in the SIM (subscriber identification module) or the mobile phone EMS memory the inside of the mobile device of inbound roamer, for each VPMN operator, the chance of the roaming communication amount that obtains entering a country is impartial.Because under typical agreement standard (for example GSM), roamer's mobile phone is when starting shooting or regain the signal covering, always seek the network of last registration, therefore have only this network to remove under the situation about covering, the network of initial random selection just can continue selected.Pass through unlapped zone (blind spot) in the VPMN field of roamer under registration at present, under the typical situation, his mobile phone will be converted to another VPMN from this current VPMN.

Owing to following one or more reasons, inbound roamer plans to move to another VPMN from a VPMN.At first, because each VPMN network all has some blind spot (comprising that some point only has very faint signal or even do not have a signal), if therefore do not corrected by the roaming steering technology of some type, the overlay area that being converted to VPMN automatically provides can cause inbound roamer mean allocation between the VPMN of all competitions operator.For most of networks, the tiny blind spot, power control, signaling interference, the multipath of signaling and the problem of the coverage that capture-effect causes that produce owing to dynamic environment can cause this mean allocation.These reasons impel inbound roamer to change the VPMN network.Some inbound roamer will be gone to other networks by forfeiture, also has other inbound roamer from the operator of competition and arrives.

For example, shown in dotted line in Fig. 1, just leaking to a VPMN102 and the 3rd VPMN106 from the inbound roamer of the 2nd VPMN104.Similarly, the inbound roamer from the 3rd VPMN106 is just leaking to a VPMN102 and the 2nd VPMN104.Therefore, for the 2nd VPMN104 and the 3rd VPMN106, the bucket of inbound roamer (bucket) leaks.ITRS is deployed in the VPMN102, in case be used to inbound roamer under the situation of this network registration, guarantees and increase inbound roamer to remain on possibility in the VPMN102.Like this, if " bucket of leakage " is used to show the inbound roamer of the 2nd VPMN104 and the 3rd VPMN106, and show that wherein the part inbound roamer is leaking to other VPMN, the ITRS scheme of a VPMN102 reduces leakage in " bucket of leakage " last patch installing so, and " bucket of stickup " of generation inbound roamer.In other words, " bucket of stickup " guaranteed in case the inbound roamer of registering at a VPMN102 is maintained at same VPMN.Below will combine, and utilize corresponding accompanying drawing to explain, and describe the feasible method that one or more realize this target with various embodiment.

Carry out the system of basic inbound traffic redirection mechanism

Fig. 2 shown according to specific embodiments of the invention, the system 200 that the communication of the immigration roaming mobile stations 202 between a VPMN102, the 2nd VPMN104 and the local public mobile network (HPMN) 204 is controlled.When immigration roaming mobile stations 202 (or roamer) when HPMN204 roam, this immigration roaming mobile stations 202 (or roamer) is at first to the registration of VPMN operator, and is registered in the interior VPMN VLR206 of a VPMN102.Yet in some cases, immigration roaming mobile stations 202 is attempted (or being forced to attempt) to another VPMN operator registration, and is registered in the 2nd VPMN VLR208 in the 2nd VPMN104.In the middle of a specific embodiment of the present invention, the one VPMN VLR206 and the integrated setting of VMSC (mobile switching centre is interviewed) in a VPMN102, the 2nd VPMN VLR208 also with the integrated setting of the VMSC in the 2nd VPMN104, although VPMN VLR can have different logical addresses with VMSC.User profiles (profile) data corresponding to immigration roaming mobile stations 202 are stored in the HPMN HLR (local public mobile network's attaching position register) 210 that is positioned at HPMN204.

The roaming signaling corresponding to immigration roaming mobile stations 202 at a VPMN102 is routed between switch/roaming STP (signalling transfer point) 212 and international STP1 214.The roaming signaling corresponding to immigration roaming mobile stations 202 at the 2nd VPMN104 is routed between switch/roaming STP (signalling transfer point) 216 and international STP2 218.Between a HPMN204 and the VPMN102, and the signaling between HPMN102 and the 2nd VPMN104 is utilized SS7 (Signaling System 7(SS-7)) signaling architecture 220 and is transported, wherein the SS7 signaling architecture comprises international STP3 222, and this world STP3222 is linked to the exchange/roaming STP224 in the HPMN204.The signaling that exchanges between heterogeneous networks is based on the TCAP signaling of (comprising MAP (MAP), CAP (Camel applying portion) or the like).In the middle of another instantiation of the present invention, the signaling that is exchanged is based on the route signaling of SCCP (SCCP).

Owing to following one or more reasons, even immigration roaming mobile stations 202 is registered to a VPMN104, it still attempts to register to the 2nd VPMN104.At first, under the situation that signal strength signal intensity is faint or lose the overlay area in a VPMN102, immigration roaming mobile stations 202 can attempt to change the VPMN network.Secondly, because the new available techniques in the 2nd VPMN104, for example GPRS or 3G, immigration roaming mobile stations 202 can be selected the 2nd VPMN104.In the middle of in concrete enforcement the of the present invention, the 2nd VPMN104 attempts communication redirection with immigration roaming mobile stations 202 to the 2nd VPMN104 self.VPMN operator attempts the communication redirection of inbound roamer to being known as inbound traffic redirection (ITR) below the trial of self network.

In the middle of an alternative embodiment of the invention, immigration roaming mobile stations 202 is redirected by the operator in the HPMN204, is directed to " recommendation " in the 2nd VPMN104 (perhaps or even " not recommending ") Virtual network operator with the roaming mobile stations 202 of will entering a country.In other words, operator's executive communication in the HPMN204 is redirected (TR), with other Virtual network operator in communication redirection to the two VPMN104 of the roaming mobile stations 202 of will entering a country, even the operator in the HPMN204 may have roaming relationships with a VPMN102.In the middle of another embodiment of the present invention, this network reselection may also more prefer to the 2nd VPMN104 because the PLMN timer of the recommendation on the immigration roaming mobile stations 202 has shown with respect to a VPMN102.Immigration roaming mobile stations 202 control the income of having deprived a VPMN102 from inbound roamer.

System 200 comprises ITR module 226, the 226 monitoring communications between a HPMN204 and a VPMN102 of this ITR module, and after provide one or more message of necessity to attempt with communication redirection to the VPMN102.In the middle of one embodiment of the present of invention, ITR module 226 is disposed by a VPMN102, so that the TR that operator was implemented in the HPMN204 is attempted, and is attempted checking by the ITR that the 2nd VPMN104 implements.ITR module 226 comprises detecting unit 228 and redirected unit 230.In the middle of one embodiment of the present of invention, detecting unit 228 monitoring/detections in a VPMN102 switch 212 and international STP1 214 between the exchange signaling.This is known as passive monitoring.

In the middle of an alternative embodiment of the invention, ITR module 226 in interior signaling (in-signaling) path mode active interception from switch (or roaming STP) 212 or from the signaling of international STP1 214.Further, in this case, switch 212 is configured to the exchange of the first registration cancellation message between an auxiliary HPMN204 and the VPMN102, one or more registration message and one or more registration cancellation message.Therefore, monitoring or detection that communication redirection is attempted are carried out the i.e. passive monitoring of signaling or initiatively monitoring under two kinds of patterns.In the middle of one embodiment of the present of invention, all pass switch 212 and the exchange signaling all be based on SCCP/TCAP (SCCP/TCAP Transaction Capability Application Part) signaling.

Below, this " initiatively " monitoring is replacedly used with interior signaling mode.In interior signaling mode, ITR module 226 is deployed on the roaming SS7 path by configuration switch 212 (or roaming STP), passes ITR module 226 with route forwarding country internet roaming SCCP communication.In exemplary route, the main road of the international SCCP that enters communication of going to E164 VPMN VLR206 from international STP1 214 is by being configured to pass ITR module 226.Yet secondary route is maintained at VPMN VLR206.So doing is under the situation about breaking down in ITR module 226, for the communication route provides redundant path.Similarly, any international SCCP communication of outer of going to the E214 address of immigration roaming mobile stations 202 from HPMN204 is configured to pass ITR module 226.Yet second (secondary) route is gone to international STP3 222.To those skilled in the art, apparently, utilize the different method for routing of combination wherein to be used, and do not influence the work of native system or this method.

E214 is numbering plan (NP), is used to send in the GSM network the relevant message of mobile management.E.214 numbering is that IMSI (international mobile subscriber identity) by roaming mobile stations draws, and is made up of two parts.At first, E164 part is made up of the country code and the network code of following thereafter.The second portion of numbering is made up of subscriber identity code (MSIN) part of IMSI, and this MSIN partly discerns individual user.E.214 the numbering be with E.164 the numbering separate transmission because they have different numbering plan indicating devices (NPI).Yet,, can utilize the Global Title analytical table (analysistable) that is used in E.164 numbering throughout again except the final purpose network of message.

Use the inbound traffic redirection route of TT (map table)

Under the identical situation in the address of VPMN VLR and VMSC, SubSystem Number (SSN) can be used for separating route.For the technical staff, apparently, depend on the network type in a VPMN102 and the 2nd VPMN104 for ability, other Route Selection also is feasible.For example, for fear of circulation, depend on the network architecture in the VPMN, communication redirection can or utilize alternative types (or map table) (TT) to carry out, perhaps utilize message transfer part (MTP) route and carry out, this MTP route comprises international STP signaling point code (SPC) and exchange/roaming SPC.In the middle of another example, operator in the one VPMN102 can carry out MAP and analyze, and only from E164 message, canceling position (Cancel Location) message is redirected from international STP1 213 and passes ITR module 226, with signaling load in the remarkable minimizing.Use the technology of TT before considering, switch 212 and ITR module 226 are configured, the international SCCP signaling message of sending out that be used to enter and outer.For example, for the message that enters at switch 212, the TT of this message is 0, and called party address (CdPA) is not self, and E.214 numbering plan (NP) be, then DPC (destination end coding) is set to ITR module 226, and destination TT is 32.Similarly, if CdPA is VPMN VLR206, E.164 NP is, and TT is 0, and then DPC is set to ITR module 226, and destination TT is 32.This means that any E164 message that enters at switch 212 at first is directed to ITR module 226.In outer message from switch 212, TT is 32, CdPA is not oneself and NP under the situation E.214, DPC is set at international STP1 214, destination TT is 0.Further, if TT be 32 and CdPA as VPMN VLR206, and NP is E164, then DPC also is set to VPMNVLR206, and destination TT is 0.In all these situations, the route indicator of SCCP CdPA (RI) can remain unchanged (for example on Global Title).

Do not use the inbound traffic redirection route of TT

Consider to use second kind of technology of MTP route, the message that switch 212 is configured to enter is sent to the DPC in ITR module 226, wherein the NP of this message for E.214 and CdPA be not oneself.And, be VPMN VLR206 at CdPA, NP is under the situation of E164, DPC is transformed into ITR module 226.For oneself the message that will send out outward of network (VPMN102) is sent to switch 212 from ITR module 226 routing configuration, DPC is set to VPMN VLR206, and with RI as SubSystem Number/do not change RI.Similarly, for the message that will send out outward of (HPMN) of the world is sent to switch 112 from ITR module 226 routing configuration, DPC is set to international STP1 214, and RI still remains GT.Based on different the entering and the outer message of sending out from switch 212, ITR module 226 sends different message as one or more registration messages, to attempt communication redirection to the VPMN102 with immigration roaming mobile stations 202.

Under all ungratified situation of above-mentioned condition, it is that TT type or MTP route are used that the SCCP message that all enter relies on, and is back to switch 212 (or roaming STP) or VPMN VLR206 and can change biography (relay) respectively.In above-mentioned method, SCCP, rather than TCAP is changeed biography.Yet to those skilled in the art, apparently, similarly signaling flow also can pass for the commentaries on classics based on TCAP and define.In this case, for each pseudo-LUP (position renewal) message that opens certainly, new transaction will be started by ITR module 226, and each new mapping will be established, and comes new transaction identification and the initial transaction identification that starts of starting associated.

The current redirecting signaling stream of basis immigration roaming

Fig. 3 shown according to specific embodiments of the invention, the flow chart that the inbound traffic redirection between a VPMN102, the 2nd VPMN104 and the HPMN204 is carried out.One receive at a VPMN102 place from one or more registrations cancellation message of HPMN204 the first registration cancellation message time, the detecting units 228 in the ITR module 226 just detect may the changing of registration of described immigration roaming mobile stations 202.In the middle of one embodiment of the present of invention, when LUP message 302 is used as first registration message when the 2nd VPMN104 just is being sent to HPMN104, just may the changing of described registration of immigration roaming mobile stations 202 inferred.Attempt (perhaps being forced to attempt) after the 2nd VPMN104 registration at immigration roaming mobile stations 202, this LUP302 is sent by the 2nd VPMN104.Therefore, when there not being new registration message to be received from a VPMN102, and detecting unit 228 detects described one or more registrations cancellation message when the receiving of a VPMN102 place, this detecting unit 228 can infer that the roaming mobile stations 202 of entering a country attempting to register under the 2nd VPMN106.In the middle of a specific embodiment of the present invention, the described first registration cancellation message is the Cancel Location message 304 that sends from HPMN HLR210, and this message is used for cancelling the registration of immigration roaming mobile stations 202 to a VPMN102.The first registration cancellation message of described one or more registration cancellation message directly is sent to a VPMN VLR206, and the cancellation of registration subsequently message quilt is in ITR module 226 taps (tapped).

To those skilled in the art, apparently, independent mutually from the CancelLocation304 treatment progress (wherein this treatment progress starts from the new position renewal that is received in HPMN HLR210) of HPMN HLR210 with the state that upgrades treatment progress in the position of HPMN HLR210.In other words, when immigration roaming mobile stations 202 1 changed to the 2nd VPMN104, a VPMN102 just made Cancel Location304 treatment progress be independent of the state that upgrades treatment progress in the position of HPMN HLR210.Afterwards, after the one or more registrations cancellation message of receiving from HPMN204, be redirected unit 230 by one or more registration messages are sent to HPMN204 from a VPMN102, and attempt communication redirection to the VPMN102.

For each registration that is detected cancellation message, one or more registration messages, and in first Preset Time interval (T0), sent by the ITR module in a VPMN102 226, be registered as the transaction of success up to a registration message.To those skilled in the art, apparently, the different function of being correlated with detecting unit 228 and redirected unit 230 only is as exemplary purpose.Yet the two any functional characteristic is following will be all relevant with ITR module 226.In other words, any function of being carried out by detecting unit 228 or redirected unit 230 can replacedly be carried out separately by ITR module 226.

ITR module 226 can with detecting unit 228 and the 230 integrated settings of redirected unit, and be configured in the VPMN102.In the middle of a specific embodiment of the present invention, for each registration that is detected cancellation message, described one or more registration messages are the location update messages (LUP) 306 from a VPMN102.These LUP message are that (LUP) message is upgraded in the position of forging.Yet last in the LUP message 306 of these forgeries is registered as the transaction of success, unless time T 0 exhausts and all message was sent out in the default time interval (T0).In the middle of example of the present invention, time interval T0 is less than or equal to the position of finishing at HPMN HLR210 place from the 2nd VPMN104 and upgrades the needed time of treatment progress.Successful LUP transaction means the exchange of other necessary message, for example MAPISD is (in the MAP, insert user data) and MAP ISD ACK (in the MAP, insert user data, confirm) (according to basic agreement), also be successful exchange between a VPMN102 and HPMN HLR210.

Described one or more registration message utilizes the GT of one or more each CancelLocation message that receive and is sent out.In the middle of a specific embodiment of the present invention, the GT of a VPMN VLR206 is utilized.In the middle of another example of the present invention, GT is selected from the one or more GTs relevant with a VPMN102.When the new position from the ITR module 226 in the VPMN102 is upgraded, upgrade from the position before the VPMN104 complete successfully before take place, or when taking place in the process from completing successfully of the renewal of the position before the VPMN104, HPMN204 (or HPMN HLR210) will be sent to the 2nd VPMN104 with TCAP/MAP abort message or system failure message.Therefore, generate by the 2nd VPMN104 at the network failure of the location registers of the 2nd VPMN104, and towards immigration roaming mobile stations 202.Exchange so be redirected the 230 pairs of one or more registration messages 306 in unit, wherein this one or more registration messages 306 and the one or more registrations that are received from HPMN204 cancel in the message 304 each is corresponding.After error message was created in immigration roaming mobile stations 202, described one or more registrations cancellation message 304 were after each registration message 302 is sent by immigration roaming mobile stations 202 and be sent out.The radio communication message that has caused going to the immigration roaming mobile stations from the internet message of HPMN204 to the two VPMN104, this radio communication message is represented network failure, wherein the example of these internet messages is, but is not limited only to: depend on MAP U/P ABORT (MAP user/supplier ends), MAP_CLOSE (MAP_ closes), TCAP-abort (TCAP termination) and the system failure that the HLR in HPMN carries out.

Be received in the error messages in the message that enters on the interface of makeing mistakes, be mapped to according to the message that is equal on the wave point of 3GPP29010 standard.Table 1 has shown that part message maps to the snapshot of wave point (24.008) from network interface (29.002), and has the corresponding error code of each interface.These only are examples, are not to be used for limit catalogue or conduct representative

(24.008) be " network failure " (code 17 of makeing mistakes), and be received on the immigration roaming mobile stations 202 that the roaming mobile stations 202 of entering a country was afterwards waited for 20 seconds or 15 seconds before consolidated network is attempted next time equally.Similarly, other 24.008 error messages also has 29.002 error messages that are equal to.

When immigration roaming mobile stations 202 minorities several times (for example 4 times) when running into this error message, it selects other network (comprise and select same network once more).This new network is from new scanning or select to select the existing scanning.This existing scanning has the possibility of tracking from the small-signal of a VPMN102.When immigration roaming mobile stations 202 has obtained network failure (error code 17), it is by before selecting other network, equaling sending registration message 202 for the expectation number of times of existing network (the 2nd VPMN104) at most, and attempts once more.In the middle of one embodiment of the present of invention, this expectation number of times is 4 times.Each Cancel Location304 that attempts once more all having produced for a VPMN102.This Cancel Location message is received at ITR module 226 places, and ITR module 226 sends the LUP message 306 (that is one or more registration message) of corresponding forgery immediately.If the roamer just attempting with a VPMN102 same country in competition VPMN network, the LUP treatment progress of forgery finally causes entering a country roaming mobile stations 202 to the trial once more of (comprising the 2nd VPMN104) of other network.And, under the situation of the blind spot in a VPMN (that is small-signal zone), any delay of the registration process process of the 2nd VPMN104 is included in a VPMN102 and regains signal strength signal intensity for immigration roaming mobile stations 202 provides the chance that is back to a VPMN102 once more.In case one or more LUP message that are sent to the forgery of HPMN204 by ITR module 226 in a VPMN are successfully talked about, sending before the registration message of the 2nd VPMN104 is finished, HPMN204 is sent to the 2nd VPMN104 with refuse information.In the middle of a specific embodiment of the present invention, LUP refusal make mistakes (reject error) be sent to the 2nd VPMN104 by HPMN204 as refuse information.Therefore, the network (comprising the 2nd VPMN104) of attempting other at immigration roaming mobile stations 202 before, the treatment progress of from 302 to 308 message is repeated more than 4 times or 4 times.

Under a VPMN102 was not found situation in the existing catalogue of the available PLMN that is present in the roaming mobile stations 202 of entering a country, different (may be interrupted) PLMN search plans were used, and purpose is to make the access time minimize when keeping battery life.For example, BCCH (Broadcast Control Channel) carrier wave is paid the utmost attention in search, and this bcch carrier has the very high possibility available and PLMN permission that belongs to.This comes to be found and registration once more by immigration roaming mobile stations 202 for the better chance of a VPMN102 of having disposed ITR module 226.It is long more that the performed pseudo-LUP of ITR module 226 attempt the time, and under the many more situation of quantity, immigration roaming mobile stations 202 is just good more to the chance of VPMN102 registration.

In the middle of an alternative embodiment of the invention, similarly the signaling exchange is performed under GPRS.System 200 in the present embodiment comprises the SGSN relevant with the 2nd VPMN104 (service GRPS support node) and another SGSN relevant with a VPMN102.When described one or more registrations cancellation message are sent to SGSN in the VPMN102, rather than a VPMNVLR206 time, the exchange of ITR module 226 monitoring (on one's own initiative or passively) Cancel Location message.Further, the SGSN in the VPMN102 sends one or more pseudo-GPRS LUP message.

With reference to figure 3, as previously mentioned, from need in the default time interval (T0), being sent out of HPMN204 to the VPMN102 for each one or more pseudo-LUP message 306 of registering cancellation message.T0 is that position renewal treatment progress is finished the time interval that is spent at HPMN HLR210.Yet, in current ITR attempts all from ITR module 226, upgrade also and need be sent out in (T1) and/or in the transmission threshold number of setting up new registration procedure at interval from all pseudo-positions of HPMN204 to the VPMN102 at second Preset Time about all registration cancellation message.The T1 time interval is to set up new registration procedure timer.Set up new registration procedure the value representation of timer and leave the time of the ITR trial of carrying out the immigration roaming mobile stations for.In the middle of an alternative embodiment of the invention, the pseudo-LUP message 306 that all current ITR attempt is sent out equaling to set up new registration procedure setting up new registration procedure under the threshold number of counter at most.Set up new registration procedure counter and shown when ITR module 226 is deployed in a VPMN102, the number of times that the registration of 202 couples the 2nd VPMN104 of immigration roaming mobile stations is attempted.The threshold value of setting up new registration procedure of setting up new registration procedure counter provides the upper limit for the treatment of by pseudo-LUP message 306 quantity of ITR module 226 transmissions.In the middle of a specific embodiment of the present invention, T1 equals to multiply by the time interval of the maximum between the one or more pseudo-LUP message 306 (after the network failure #17) of attempting for the position renewal and the product of the maximum time of selecting other network (comprising the 2nd VPMN104) summation at interval for the quantity of the competitor's Virtual network operator in the country.

For example, but be not limited only to, if the quantity of the competitor operator in the country is 5, the time interval of attempting same network again is 45 seconds, and the time interval of attempting other network is 45 seconds, then T1=5* (45+15)=300 second.The time interval of attempting same network can be between 45 seconds to 150 seconds scope, and the time interval of attempting other networks can be between 15 seconds to 30 seconds scope.In exemplary situation, the value of T1 can be at 60 seconds to 300 seconds.In the middle of another specific embodiment of the present invention, T1 equals to stop threshold value.This termination threshold value represents to set up new registration procedure the time of counter reset, and this purpose that resets is any further Cancel Location from HPMN HLR210 is treated as new ITR sequence.

Set up new registration procedure counter and originally be set to zero, and set up new registration procedure timer and be set to stop threshold value.In the middle of a specific embodiment of the present invention, the threshold value of setting up new registration procedure of setting up new registration procedure counter is made as (N-1) * 4, and wherein N is the quantity of competitor's carrier network in the country that is configured of ITR module 226.Receive the code #17 that makes mistakes based on GSM408 or 3GPP 24.008,, just select the 4 202 pairs of same networks of roaming mobile stations (that is the 2nd VPMN104) of representing to enter a country to attempt 4 times altogether.Finish before finishing because ITR attempts upgrading treatment progress in the position of the 2nd VPMN104, so the value of N elects 2 as, promptly supposing has two networks in this country.This has also increased the possibility that the roaming mobile stations 202 of entering a country is back to a VPMN102.

In the middle of one embodiment of the present of invention, only after the 2nd VPMN104 having been finished the position renewal, HPMN HLR210 is distributed to a VPMN VLR206 with Cancel Location304.In this case, ITR module 226 utilizes its GT at first to send the LUP of forgery.HPMN HLR210 is distributed to the 2nd VPMN104 with Cancel Location afterwards.Yet in this case, immigration roaming mobile stations 202 will can not receive any information or notice before any MO (move and initiate) activity is arranged.Therefore, the ITR module can not received the further registration cancellation message from HPMNHLR210, and it can not carry out the position renewal of further forgery.Under these circumstances, because it is nonsensical to carry out the ITR trial on such HPMN HLR, so HPMN HLR210 can be put on the blacklist.Blacklist can regularly empty, to cater to the configuration change of HPMN HLR210 in the future.For such HPMN HLR, when it is not put on the blacklist, when after the position renewal treatment progress of one or more registration cancellation message on the 2nd VPMN104 finishes, being received, ITR module 226 is in response to from the receiving of one or more request messages of HPMN HLR210, and representative immigration roaming mobile stations 202 sends one or more response messages.In the middle of one embodiment of the present of invention, described one or more request message comprises, but be not limited only to: from the MAP PSI (MAP of HPMN204, provide user profile), MAP PRN (MAP from HPMN204, Provide Roaming Number), and MAP Forward SMS (MAP, the transferring short messages service), wherein from the MAP PRN of HPMN204 as the calling result of incoming call to the roaming mobile stations number of entering a country, MAP Forward SMS is as the short message service (SMS) from SMSC (short message service center) to the roaming mobile stations number of entering a country.ITR module 226 representative immigration roaming mobile stations 202 are with Absent Subscriber (user's absence) message message and sending in response.

Further, the redirected counter of all inbound roamers is defined.The redirected counter of each HPMN also was defined in the time interval that can set (for example 1 hour).In the middle of one embodiment of the present of invention, can and be defined for each the immigration roaming mobile stations in the HPMN in the redirected limit of the redirected counter in the time interval that can set.System can refer to and be used for the counter that the proprietary application logic is controlled these types of immigration TR treatment progress and result, and the counter of the type is used to count the trial and the success of each local network or visited network.An example of this proprietary application logic is the allocation of communications that control is received from various HPMN.Especially under the situation of capacity shortage, this logic can be used to guarantee according to rule, and visited network provides service to the roamer of the affiliate with priority of recommendation from it, perhaps carries out the processing of priority in multiple external network.In the middle of one embodiment of the present of invention, when ITR trial and success or failure, one or more redirected counters just increase counting.

Exhaust and the counting of setting up new registration procedure counter remains under the situation below 5 in the time of setting up new registration procedure timer, then expression immigration roaming mobile stations 202 may be blocked in the 2nd VPMN104.This obstruction may be because the problem of mobile phone.Yet if the mobile phone problem, the counting of setting up new registration procedure counter will be greater than 1.Remain at the counting of counter under 1 the situation, after the 2nd VPMN104 completing place was upgraded, HLR then only was distributed to a VPMN102 with Cancel Location.When HLR upgraded the 2nd VPMN104 completing place, HPMNHLR210 was put on the blacklist in a period of time, attempted and can't carry out further ITR.

The counter management

Fig. 4 and Fig. 5 shown according to specific embodiments of the invention, to the flow chart that various different types of applied logics are described, wherein said applied logic in conjunction with ITR attempts the application specific treatment technology and VAS is provided before can be examined.Set up new registration procedure counter and set up new registration procedure timer (as introducing) and be used to immigration roaming mobile stations 202 is used a kind of or multiple dedicated processes technology in conjunction with Fig. 3.Whether in other words, the value of counter and timer all is used to decision needs to provide dedicated processes and VAS.In step 402, check whether the value whether time set up new registration procedure counter exhaust (then) and set up new registration procedure counter equals 1.If then in step 404, sets up new registration procedure counter reset and make zero, and the thin note of statistics is finished.The thin note of statistics can comprise the value that changes one or more redirected counters.The dedicated processes technology also can be performed.

Afterwards, in step 406,226 monitoring of ITR module are gone to the LUP message of HPMN HLR210 and are gone to the Cancel Location message of a VPMN VLR206.Further, still in step 406, pseudo-LUP message is handled by ITR module 226.ITR module 226 is used the GT of oneself once more as VLR, VMSC on same IMSI or the same inbound roamer and SCCP CgPA (in the SCCP, the calling party address), issue pseudo-LUP.ITR module 226 oneself is finished the transaction of pseudo-LUP.In step 408, for the pseudo-LUP message of each success, MSISDN (mobile station ISDN number) and the HLR of the IMSI of immigration roaming mobile stations 202 are recorded.

In step 410, for each LUP message from self network (VPMN102), ITR module 226 record VLR and IMSI., all be hunted down for the VLR and the IMSI of roaming mobile stations 202 herein, and no matter the whether success of LUP message.In step 412, ITR module 226 checks whether IMSI is put on the blacklist.If pseudo-LUP message in response to the ITR module, represent ODB (Operator Determined Barring) locking of unknown subscriber, RNA (roaming does not allow), roaming, the RNA the lane place in (because restriction, area service are signatory, country roam or the like) and have the error messages that returns, then IMSI will be piped off by ITR module 226, forbid pseudo-LUP message subsequently, register to a VPMN102 once more up to IMSI.If be put on the blacklist, ITR module 226 can be abandoned the ITR trial so.

If be not put on the blacklist, then in step 414, timer is set up new registration procedure in inspection, and whether the time exhausts.If exhaust, then in step 416, set up new registration procedure counter and set up new registration procedure timer and all be reset.For the Cancel Location message of going to VPMN VLR from the HPMN HLR210 on the IMSI, wherein this Cancel Location message comprises for the pseudo-LUP message of ITR module 226 and is sent to the Cancel Location message of this ITR module 226, the ITR module at first writes down the HLR for IMSI, and, check whether/IMSI registers in the new VLR to same VPMN (that is a VPMN102) in by the LUP message that is recorded before the IMSI of the 2nd VPMN104 to HPMNHLR210.

Yet, do not exhaust if set up new registration procedure timer time, in step 418, ITR module or other system unit can check that whether new VLR in same VPMN.At VLR is same, and IMSI set up new registration procedure timer and the time exhausts under the situation of (also be zero), then in step 420, check whether set up new registration procedure counter counts and equal zero, if null words are then abandoned ITR and attempted.

If set up new registration procedure the counting of counter and is not zero, then in step 422, the counting summation that is redirected counter is increased, and is made as zero once more for the counter of setting up new registration procedure of IMSI, and is made as the termination threshold value once more for the timer of setting up new registration procedure of IMSI.In other words, the statistics bookkeeping is performed.

When the output of step 418 is under the situation of the different VLR in the same VPMN, in step 424, ITR module 226 checks whether the counting of setting up new registration procedure counter equals threshold value.Equal to set up new registration procedure under the situation of threshold value operation below can in step 426, carrying out at the counting of setting up new registration procedure counter:

1. increase the counting summation that is redirected counter.

2. increase the counting summation of the redirected counter of each HPMN.

3. increase the counting summation of the redirected counter of each IMSI under each time interval.

4. will set up new registration procedure counter reset to zero, the timer of grade again of IMSI will be reset to the termination threshold value.

5. selectively, ITR module 226 is carried out some value-added services.

Yet, be not equal at the counting that redirects counter under the situation of threshold value, in step 428, ITR module 226 is set up new registration procedure LUP, MSISDN and the HLR of record IMSI, and increase the counting of setting up new registration procedure counter.

Inbound traffic redirection based on the enhancement mode position

Fig. 6 shown according to specific embodiments of the invention, carries out the flow chart based on the ITR of enhancement mode position between a VPMN102, the 2nd VPMN104 and the HPMN204.Left under the situation of the country that is deployed with ITR module 226 at immigration roaming mobile stations 202, this ITR module continues pseudo-LUP message is sent to HPMN HLR204.For fear of this situation, be performed based on the ITR of enhancement mode position.When receiving the first registration cancellation message (Cancel Location304) from HPMN204 at a VPMN102 place with reference to figure 6,, the detecting units 228 in the ITR module 226 just detect may the changing of registration of described immigration roaming mobile stations 202.Upgrade (LUP) message 302 when the position and be used as first registration message when the 2nd VPMN104 just is being sent to HPMN204, just may the changing of described registration of immigration roaming mobile stations 202 inferred.Attempt (perhaps being forced to attempt) after the 2nd VPMN104 registration at immigration roaming mobile stations 202, this LUP302 is sent by the 2nd VPMN104.Therefore, detecting unit 228 can infer the immigration roaming mobile stations 202 attempting under the 2nd VPMN104, to register.Further, detecting unit 228 detects described one or more Cancel Location message 304 as registration cancellation message receiving at a VPMN102 place.Described registration cancellation message sends from HPMN HLR210, cancels the registration of immigration roaming mobile stations 202 to a VPMN102.The first registration cancellation message in the described one or more registration cancellation message directly is sent to a VPMN VLR206, and the cancellation of registration subsequently message in ITR module 226 by tap (tapped).Further, as previously mentioned, from HPMN HLR210, attempt being independent of in the position of HPMN HLR210 by the registration of immigration roaming mobile stations and upgrade the treatment progress state at the Cancel Location304 that VPMN104 starts.

In the specific embodiment of execution based on the ITR trial of enhancement mode position, after the Cancel Location304 message of receiving from HPMN204, and CancelLocation304 message change is being passed (relay) to the VPMN VLR206, ITR module 226 synchronously sends search request message with each of one or more pseudo-LUP message 306.Described search request message is sent to the VMSC that immigration roaming mobile stations 202 is learnt at last, to collect the position area information of immigration roaming mobile stations 202.In the middle of one embodiment of the present of invention, search request message is the Search MS (MAP message) with pseudo-LUP message 306 synchronized transmissions.The information of receiving after sending Search MS shows whether the roaming mobile stations 202 of entering a country also is being deployed with under the coverage of a VPMN102 of ITR module 226.In the middle of an alternative embodiment of the invention, this search request message be with pseudo-LUP message 306 synchronized transmissions and Cancel Location304 message is changeed reach a VPMN VLR206 before and the PageMS message that sends.Search MS initiatively and in the passive monitoring pattern is being sent out, and Page MS initiatively is being sent out in the monitoring (that is interior signaling paths pattern).Page MS is the paging immigration roaming mobile stations 202 in (or current) band of position of learning in the end only, and all bands of position of the VMSC that Search MS search last (or current) is learnt.Yet for these two kinds of message, if search request message has error message, enter a country roaming mobile stations 202 present located networks and country then can not be identified.

For fear of this problem, now another specific embodiment of carrying out location-based ITR trial is described.With reference to figure 6, when a Cancel Location304 when a VPMNVLR206 is received, be adjacent to pseudo-LUP message 306 be sent to before the HPMN HLR210, ITR module 226 sends route requests.In the middle of a specific embodiment of the present invention, route requests is SRI-SM (routing iinformation that a sends SMS message) message 602.This is a most preferred embodiment.In the middle of an alternative embodiment of the invention, route requests is SRI (transmission routing iinformation) message.In the middle of an embodiment more of the present invention, route requests is ATI (any time interrogation) message.SRI-SM message is sent out on the MSISDN of immigration roaming mobile stations 202.In the middle of a specific embodiment of the present invention, after receiving SRI-SM ACK message, ITR module 226 sends pseudo-LUP message 306.In the middle of another specific embodiment of the present invention, the ITR module sends pseudo-LUP message 306 immediately after having sent SRI-SM message, and does not wait for SRI-SMACK message.If HPMN HLR210 has obtained roamer's VMSC (or VLR) position immediately from new network site is upgraded, even before this new network site renewal was not also finished, then SRI-SM ACK message will be returned VMSC.After the VMSC that learns immigration roaming mobile stations 202, and set up new registration procedure counter when being in threshold value as the IMSI of immigration roaming mobile stations 202, ITR module 226 is not carried out the ITR trial, but in the middle of a specific embodiment, for immigration roaming mobile stations 202 provides VAS.

When ITR attempts failure, and the response of route requests has been when having returned competitor's network, and VAS then is provided.The example of VAS include but not limited to: send " winning back again " note or " Hope you'll come again for thank you " note.Yet, if HPMN HLR210 does not return anything, perhaps returned the error message of SRI-SM request, instant pseudo-LUP message 306 is still upgraded treatment progress with the current position of HPMN HLR210 and is impacted competitive environment.In the middle of one embodiment of the present of invention, under the number of times that can set, lack response to route request (SRI-SM) from HPMN204, perhaps under the situation that has the error messages to route request (SRI-SM) (for example system failure, unexpected data value or data omission etc.) from described HPMN204 under the number of times that can set, ITR module 226 is charged to blacklist with the HLR relevant with HPMN204 in the default time interval.

If pseudo-LUP is too early sent after SRI-SM, because typically, for route request information, HLR will provide higher preferential to location update message, so SRI-SM even the transmitter GT (that is ITR module GT) that may return pseudo-LUP are as the VMSC address.In this case, ITR can increase the delay period of setting (several milliseconds) of ensuing SRI-SM and pseudo-LUP sequence, arrives threshold value up to whole delay period.The increment of each pseudo-LUP in ITR attempts needn't be all the same, and for example, first increment is 0, and ensuing increment is 2ms, and ensuing more only is 1ms etc.Threshold value can be in 20ms to 200ms scope.When being reached for the whole interval that is delayed of HLR and this situation when having taken place repeatedly, HLR can be credited to blacklist, forbids further SRI-SM message operation.When HPMN HLR210 was put on the blacklist before each pseudo-LUP message 306, when forbidding that further SRI-SM inquires, it is hinting, when the Cancel Location304 of immigration on the roaming mobile stations 202 when HPMNHLR210 receives, if and HLR is credited to blacklist for above-mentioned reasons, ITR module 226 has only been issued pseudo-LUP message 306, and before without any route requests (SRI-SM).

Have return from the VMSC of SRI-SM ACK as situation to the response of SRI-SM message under, after in this response, using the applied logic of some preset standard, ITR module 226 decision this VMSC in the 2nd VPMN104 networks whether right and wrong ITR attempts.Afterwards, pseudo-LUP message subsequently (if this LUP is published then should puppet LUP message comprises follow-up message after SRI-SM ACK) will can not be sent to HPMN HLR210.The ITR of the immigration roaming mobile stations 202 that in other words, is just leaving attempts can not being dropped.Example with some applied logic of the preset standard that decides the VMSC right and wrong ITR candidate who returns from SRI-SM request include but not limited to following:

1. this VMSC is in the country different with a VPMN102.

2. this VMSC is in the VPMN network of the blacklist in the country identical with a VPMN102.For example, when two VPMN networks have certain agreement (for example merging or friendly transaction) of not carrying out ITR mutually.

3. this VMSC is in the VPMN network of the blacklist in any national different with a VPMN102.For example, when two VPMN networks have certain agreement (for example merging or alliance of group) of not carrying out the ITR that resists the other side mutually.

This VMSC belong to certain country (with the country of a VPMN102 can be identical or inequality) in network, this network satisfies some SS, these standards include but not limited to:

A. this network has surpassed the threshold value of its ITR that is assigned with trial in the time interval that can set.For example, this time interval can be infinitely great.

B. this network surpasses the threshold value of its immigration TR success in the time interval that can set.For example, this time interval can be infinitely great.

C. this network is with the ITR that is under an embargo in (time band) to attempt in the time district of some kind.

D. this network has surpassed it all ITR are attempted or successful allocation proportion.For example, can set limiting value, making does not have the ITR for the HPMN network to attempt/successfully surpass all ITR trial or successful special ratios

Refer again to Fig. 6, require to be sent out in (T0) at interval at first Preset Time for one or more pseudo-LUP message 306 from each registration cancellation message of HPMN204 to the VPMN102.This T0 upgrades the used time interval of treatment progress in HPMN HLR210 completing place.Yet, in ITR attempts, for from all registration cancellation message of HPMN204 to the VPMN102, upgrade also need and/or set up new registration procedure in the threshold value in the second Preset Time interval T 1 from the position of all forgeries of ITR module 226 and be sent out.The T1 time interval is to set up new registration procedure timer.The value representation of setting up new registration procedure timer is left the time that ITR that execution just desiring the inbound roamer that leaves attempts for.In the middle of an alternative embodiment of the invention, all one or more pseudo-LUP message 306 in ITR attempts is sent out with the threshold number of setting up new registration procedure that equals to set up new registration procedure counter at most.Set up new registration procedure counter and represent when ITR module 226 is configured in a VPMN102, the registration number of attempt that immigration roaming mobile stations 202 is carried out for the 2nd VPMN104.The threshold value of setting up new registration procedure of setting up new registration procedure counter provides the upper limit amount for the treatment of by the pseudo-LUP message 306 of ITR module 226 transmissions.

Before being updated in completing successfully of upgrading from the position before the VPMN104, the new position from the ITR module 226 in the VPMN102 takes place, or when taking place in the process from completing successfully of the renewal of the position before the VPMN104, HPMN204 (or HPMN HLR210) will be sent to the 2nd VPMN104 with TCAP/MAP abort message or system failure message.In the middle of one embodiment of the present of invention, LUP refusal is made mistakes and 308 is sent to the 2nd VPMN104 by HPMN204.Therefore, generate by the 2nd VPMN104 at the network failure of the location registers of the 2nd VPMN104, towards immigration roaming mobile stations 202.The radio communication message that has caused going to the immigration roaming mobile stations from the internet message of HPMN204 to the two VPMN104, this radio communication message is represented network failure, wherein the example of these internet messages is, but is not limited only to: the MAP U/P ABORT, MAP_CLOSE, TCAP-abort and the system failure that depend on the HLR in HPMN.

Dedicated processes

Aligning the current I TR that the roamer that desires to leave carries out attempts and can be carried out or abandon based on fulfiling of some standard.In the middle of one embodiment of the present of invention, if being found, immigration roaming mobile stations 202 is under the manual mode, 226 of ITR modules can be abandoned ITR and attempt.In the middle of an alternative embodiment of the invention, to attempt to have surpassed under the situation of expectation number of times at immigration roaming mobile stations 202 to the number of times of the 2nd VPMN104 registration, ITR module 226 is abandoned ITR and is attempted.The exemplary value of estimating number of times is 4.

In the middle of an embodiment more of the present invention, to attempt to have surpassed under the situation of registration threshold value at immigration roaming mobile stations 202 to the 2nd VPMN104 registration, ITR module 226 is abandoned ITR and is attempted.For example, before time that reaches any timer or threshold value, and blocking time surpassed before the particular bound at interval, if immigration roaming mobile stations 202 gets clogged after 4 times or more times are attempted, the ITR module is charged to blacklist to the IMSI of the roaming mobile stations 202 of entering a country so.This blacklist can only be that each is determined based on the frequency of failure.In the middle of this embodiment of the present invention, the registration threshold value is the blocking time of the limit at interval, and is the parameter that can set.

In the middle of a specific embodiment of the present invention, standard Network Based (for example complaining affiliate's network) and roamer's profile (for example operating position, from the obvious complaint of inbound roamer), ITR attempts being limited to blacklist and white list.If immigration roaming mobile stations 202 is back to local country, but ITR module 226 is ignorant, because there is not VMSC to be back to the SRI-SM inquiry in ITR attempts, the roaming mobile stations 202 of entering a country so continues to attempt to set up new registration procedure at HPMN or local national network, sets up new registration procedure limiting value (showing as the form of registration threshold value) up to reaching.

In the middle of an alternative embodiment of the invention, roaming mobile stations 202 is not gone to third country if ITR module 226 is recognized immigration, because there is not VMSC to be returned in the SRI-SM inquiry in immigration TR attempts, then ITR attempts and will continue, and sets up new registration procedure limiting value up to reaching.In the middle of another specific embodiment of the present invention, after the position that number of times (4) is forged if exceed the estimates in ITR attempts is upgraded, immigration roaming mobile stations 202 continues to attempt to the 2nd VPMN104 registration (being returned in the SRI-SM inquiry in immigration TR attempts because of VMSC), and ITR module 226 is abandoned the current I TR trial on immigration roaming mobile stations 202 so.This roamer who is just desiring to leave is inferred that the source is at manual mode.

In the middle of an embodiment more of the present invention, when immigration roaming mobile stations 202 was found in the non-overlay area that is in a VPMN102, ITR module 226 was abandoned ITR and is attempted.If in ITR attempts, immigration roaming mobile stations 202 continues to attempt to the 2nd VPMN104 registration (because VMSC is returned in the SRI-SM inquiry in immigration TR attempts), if and in ITR attempts, have in the middle of some other competitor's network is in, then non-overlay area can be inferred that the current I TR that ITR module 226 is abandoned on immigration roaming mobile stations 202 attempts.

If the immigration roaming mobile stations is in manually under the pattern, but because in immigration TR attempts, there is not VMSC to be returned in the SRI-SM inquiry, so ITR module 229 is not known this information, the roaming mobile stations 202 of then entering a country will be attempted to set up new registration procedure to same operator, set up new registration procedure limiting value up to reaching.Further, if the immigration roaming mobile stations 202 detected signal uncovered area that are in first VPMN102 (having disposed ITR module 226), but because in immigration TR attempts, there is not VMSC to be returned in the SRI-SM inquiry, so ITR module 229 is not known this information, the roaming mobile stations 202 of then entering a country will attempt to the country in different operators set up new registration procedure, set up new registration procedure limiting value up to reaching.

In the middle of another specific embodiment of the present invention, ITR module 226 attempts having defined the maximum of network counter for ITR, and with the maximum quantity of control competitor network, wherein the position of forging is upgraded and is published and this competitor's network of conflicting.If VMSC was back to the SRI-SM inquiry and is learnt that then this operation is done during attempted by ITR the new network site of immigration roaming mobile stations 202.Similarly, ITR module 226 attempts having defined the timer maximum for the ITR of network, upgrades the maximum duration that is published for network with the position of the forgery during ITR is attempted and controls.

In the middle of another embodiment of the present invention, ITR module 226 has defined the global redirected limit for inbound roamer in the time interval that can set.This can be based on each country or each HPMN.ITR module 226 has also defined the redirected limit for all inbound roamers of specific HPMN or country in the time interval that can set.In the middle of an alternative embodiment of the invention, the ITR module definition set up new registration procedure threshold value and timer on each VPMN VLR/VMSC or unit basis (cellbasis) (if any) because VPMN more knows clearly its coverage at specific VMSC/VLR or unit (cell).

In the middle of an alternative embodiment of the invention, ITR module 226 has defined configuration and has distributed control profile (profile) between the HPMN of inbound roamer.This configuration distributes the support of control profile to carry out the decision that ITR attempts.The configuration that ITR module 226 also activates on HPMN in different time district's bands distributes the control profile.This configuration distributes the control profile to be defined based on following one or more parameters (but being not limited to following one or more parameters):

1. Du Te inbound roamer: for example, from Vodafone ^TM15% the ITR of being no more than that the waiting of Great Britain is used on unique roamer attempts or success.

2. immigration TR attempts: for example, and from Vodafone ^TMEntire I TR on the roamer 15% the ITR of being no more than in attempting that waits to be used in of Great Britain attempts.

3. immigration TR success: for example, from Vodafone ^TMThe whole successful ITR on the roamer of waiting to be used in of Great Britain is no more than 15% ITR success in attempting.

One or more parameters described above help to determine being redirected of roamer.For example, from China Mobile ^TMInbound roamer will obtain being redirected of X%, from CHINAUNICOM ^TMInbound roamer will obtain being redirected of Y%.Exemplary X and the value of Y are 15 and 75.These values can be selected by the operator in the VPMN102.

In the middle of a specific embodiment of the present invention, the counter that configuration distributes these the one or more parameters in the control profile to be set is measured.In other words, distribute tolerance in each of above-mentioned one or more parameters, to be carried out by the counter of setting of corresponding counting.For example, be to attempt if distribute control about immigration TR, the counter that can set is made as 10, and then percentage will be attempted and be measured for per 10 ITR.Therefore, the ITR module can be defined as successful ratio:

The redirected Counter Value of the ITR success Counter Value/total that amounts to

In the middle of an alternative embodiment of the invention, if HPMN HLR swindles control in this way, promptly in another position updating process of travelling carriage, it is abandoned from the position of ITR module and upgrades, perhaps just abandon the new registration of immigration roaming mobile stations, then ITR module 226 is charged to blacklist with HPMN HLR210, forbids that its ITR in the future attempts.

1. to the location-based inbound traffic redirection of another country

In the middle of an alternative embodiment of the invention, based on the ITR of enhancement mode position mechanism even can be utilized for the inbound roamer of just desiring to leave and go to the new VPMN of another country and carry out network selecting.Be back under the situation of local country at the immigration roaming mobile stations, then ITR is abandoned.Although the HPMN network of the roamer in local country has in country's roaming, it is feasible selecting network in local country.In the middle of this embodiment of the present invention, when the trial of a VPMN being carried out ITR was unsuccessful, the ITR module was attempted to carry out ITR to the 3rd VPMN and is attempted.This that is to say of great use for alliance of group, with the 2nd VPMN network for a VPMN is the network of not recommending, the 3rd VPMN is the network of recommending for a VPMN.For example, if the immigration roaming mobile stations is from Vodafone ^TMGreat Britain (HPMN204) is just from Orange ^TMHolland is left, and is just learnt and attempt at Smartone ^TMHong Kong (new VPMN) registration is configured in Orange so ^TMThe ITR module 226 of Holland can still be carried out ITR and attempt, up to immigration roaming mobile stations 202 at Create a Simple Life (CSL ^TM) Hong Kong (the 3rd VPMN) registration.So doing is hypothesis CSL ^TMHong Kong is Orange ^TMThe affiliate of the recommendation of Holland.Work as CSL ^TMHong Kong do not have to cover or immigration roaming mobile stations 202 still under the situation of manual mode, the ITR module also can be selected to carry out ITR to another network.

Therefore, all the dedicated processes mechanism that define for ITR mechanism in country can be applied to the ITR outside national similarly.In the middle of an exemplary embodiment of the present invention, Orange Holland is for just desiring to leave this national inbound roamer is disposing ITR module 226, can distribute control for Hong Kong definition, CSL Hong Kong can obtain 70% just desire and leave the roamer who goes to Hong Kong from his network like this, Smartone Hong Kong obtains 10%, remaining 20% can go to other domestic network of Hong Kong, for example, and People or Sunday.In another exemplary embodiment, when being used on the roamer who just desires to leave who goes to the 3rd country when ITR mechanism, the ITR module can define timer maximum or network counter maximum.

Use the inbound traffic redirection of the position-based recovery of PSI

Fig. 7 has shown according to specific embodiments of the invention, carries out the flow chart of the ITR of position-based recovery between a VPMN102, the 2nd VPMN104 and HPMN204.Leave under the situation of the country that is deployed with ITR module 226 at immigration roaming mobile stations 202, ITR module 226 attempts to discern the position of immigration roaming mobile stations 202.One receive at a VPMN102 place from HPMN204 Cancel Location message 704 time, the detecting units 228 in the ITR module 226 just detect may the changing of registration of described immigration roaming mobile stations 202.Upgrade (LUP) message 702 when the position and be used as first registration message when the 2nd VPMN104 just is being sent to HPMN204, just may the changing of described registration of immigration roaming mobile stations 202 inferred.Attempt (perhaps being forced to attempt) after the 2nd VPMN104 registration at immigration roaming mobile stations 202, this LUP702 is sent by the 2nd VPMN104.Described registration cancellation message sends from HPMN HLR210, is used for cancelling the registration of immigration roaming mobile stations 202 to a VPMN102.Therefore, detecting unit 228 can infer the immigration roaming mobile stations 202 attempting under the 2nd VPMN104, to register.

A Cancel Location 704 who receives is maintained at ITR module 226.After receiving Cancel Location 704, be redirected unit 230 based on the blind spot of discerning in response to the response message that user profile message is sent to the VLR relevant in the VPMN102 with the roaming mobile stations 202 of entering a country.The first registration cancellation message change from HPMN204 pass (relay) VPMN VLR206 to the VPMN102 before, this user profile message is sent out.In the middle of a specific embodiment of the present invention, be redirected unit 230 PSI message 706 is sent to a VPMN VLR206 as described user's registration message.This PSI message 706 is based on the signaling of MAP.In the middle of a specific embodiment of the present invention, reckon with replying from the immigration roaming mobile stations, wherein this replys current position and unit (cell) of expression the one VPMN interior 102, then a VPMN VLR206 paging (page) immigration roaming mobile stations 202.In the middle of an alternative embodiment of the invention, perhaps do not have under the situation of replying from paging, a VPMNVLR206 just returns the cell position at the roamer place of learning at last.The purpose of all these variablees is to obtain the general information of blind spot, in described blind spot, is soon lost the roamer of a VPMN102.After PSI message 706 is sent to a VPMN VLR206, even before ITR module 226 is received PSI ACK message 708, ITR module 226 is changeed biography CancelLocation message 704, wherein the current position of these PSI ACK message 708 expression immigration roaming mobile stations 202.

It is processed yet PSI ACK will be independent of current I TR.Current ITR attempts and will normally continue in the active monitoring mode as described in aforementioned.Further, as previously mentioned, be independent of in the position of HPMN HLR210 from the Cancel Location704 of HPMN HLR210 and upgrade treatment progress.Then, ITR module 226 continues the ITR trial by sending pseudo-LUP message 710, in the finishing of the success of HPMN HLR210, ITR module 226 produces network failure and makes mistakes (#17) on immigration roaming mobile stations 202, force the other network of these immigration roaming mobile stations 202 trials.Afterwards, HPMN HLR210 sends the LUP refusal and makes mistakes, and generates network failures make mistakes (#17) at immigration roaming mobile stations 202.The example of the message of other expression network failure is, but is not limited only to: depend on MAP U/P ABORT, MAP_CLOSE, TCAP-abort and the system failure that HLR carries out.

In the middle of one embodiment of the present of invention, if the VPMN1021 technology of having disposed provides current roamer's position in real time and moves away information (for example by Abis interface or A interface in monitoring initiatively), ITR module 226 also can provide immigration roaming mobile stations 202 to leak to the information of competitor's network just wherein so.

In the middle of an alternative embodiment of the invention, after the ITR trial was successful on immigration roaming mobile stations 202, PSI message 706 was published.In this case, successfully after VPMN102 registration, ITR module 226 can be issued independent PSI message and obtain the unit location information at the current place of roamer the roamer who just desires to leave.This will provide the roamer just where to be lost to a VPMN102 and go to the general information of competitor's network.Before attempting, ITR sends and the PSI message of transmission after the ITR success provides the roamer who just desires to leave where to be lost to a VPMN and goes to the general information of competitor's network.

In conjunction with the inbound traffic redirection that stops communication redirection

Fig. 8 has shown according to specific embodiments of the invention, carries out the flow chart of ITR in conjunction with the obstruction TR with the HPMN startup attempts.One receive at a VPMN102 place from HPMN204 Cancel Location message 804 time, the detecting units 228 in the ITR module 226 just detect may the changing of registration of described immigration roaming mobile stations 202.Upgrade (LUP) message 802 when the position and be used as first registration message when the 2nd VPMN104 just is being sent to HPMN104, just may the changing of described registration of immigration roaming mobile stations 202 inferred.Attempt (perhaps being forced to attempt) after the 2nd VPMN104 registration at immigration roaming mobile stations 202, this LUP802 is sent by the 2nd VPMN104.Registration cancellation message is sent out from HPMN HLR210, cancels the registration of immigration roaming mobile stations 202 to first VPMN102.Therefore, detecting unit 228 can infer the immigration roaming mobile stations 202 attempting under the 2nd VPMN102, to register.Described registration cancellation message sends from HPMN HLR210, is used for cancelling the registration of immigration roaming mobile stations 202 to a VPMN102.

In the middle of this embodiment of the present invention, system's 200 (see figure 2)s also comprise and stop TR unit (Fig. 2 does not show), and this preventions TR unit is based on the TR trial to obstructing HPMN to carry out on the basis of making one or more acknowledge messages response, that sent by HPMN204 from one or more registration messages of a VPMN.These one or more registration messages are one or more pseudo-LUP message 806.In the middle of a specific embodiment of the present invention, acknowledge message is a LUP refusal error messages 808.The example of makeing mistakes during the LUP refusal is made mistakes comprises the system failure, unexpected data value (UDV), missing data or the like.In the middle of another specific embodiment of the present invention, acknowledge message is that LUP ends error messages.If any one of this two kinds of message is used as acknowledge message and receives, ITR module 226 continues to send one or more pseudo-LUP message 806, is done or threshold value (for example 10) is reached up to the LUP of success transaction.ITR module 226 representative immigration roaming mobile stations 202 send these pseudo-LUP message 806.Afterwards, HPMN204 makes mistakes LUP refusal and 810 is sent to the 2nd VPMN104.Based on the attribute in the acknowledge message 808, the ITR module determines whether utilizing prevention TR unit to use prevention TR or abandon the ITR trial.

Acknowledge message can comprise UDV, RNA, RR (roaming restriction), the system failure or missing data or other any makeing mistakes is used as attribute.As disposed the configuration of the VPMN of ITR, and if after pseudo-LUP message 806, LUP refusal 808 UDV (makeing mistakes) that comprise from the HPMN GT of special use that make mistakes for IR73 submissiveness TR, the ITR module can abandon current ITR trial so.In other words, can not produce subsequently pseudo-LUP message 806 on the roaming mobile stations 202 in immigration.If HPMN GT is only GT that is used for sending UDV in the TR scheme, then this HPMN GT is considered to be exclusively used in the TR that uses UDV.Yet, 808 be the system failure or missing data (for non-) if LUP refusal is made mistakes in compliance with IR73, stop the TR unit TR scheme of non-biddability (that is stop) in current ITR attempts, to be employed so.If stop the TR unit only to be applied to being made mistakes (for example system makes mistakes and missing value) by the employed non-biddability of HPMN TR scheme, then this prevention TR unit is known as the non-biddability TR scheme of prevention in the VPMN.ITR that integrates and prevention TR scheme are all worked under active monitoring mode and passive monitoring pattern.

If the attribute in the acknowledge message is under the situation of RNA or RR, then ITR mechanism is adjusted like this, make ITR module 226 attempt again immediately, be reached, used ITR on the roaming mobile stations 202 and attempt because can infer that HPMN204 is entering a country up to the transaction or the threshold value of success.In this case, current ITR attempts and can be abandoned.This scheme is all worked under active monitoring mode and passive monitoring pattern.Further, carrying out ITR, only after the read-around ratio of setting of the pseudo-LUP message 806 that immigration roaming mobile stations 202 fooled RNA are received in acknowledge message, abandoning the decision of ITR and can be inferred in order to confirm HPMN204.Can be prevented from the TR unit based on the situation of OTA (aerial download) and handle independently, because it does not need and binding is upgraded in the position.Especially in the active monitoring mode, ITR attempts and can combine with GLR (Gateway Location Register) technology.

Method based on GLR

Fig. 9 shown according to specific embodiments of the invention, carries out or the system diagram of additional ITR by using the GLR technology.System 900 comprises GLR902, and this GLR902 is configured on the main frame position to be used for a plurality of VPMN operator by international SS7 carrier wave or common carrier wave 904.Exemplary VPMN operation face is VPMN1 906, VPMN2 908, VPMN3 910 and VPMN4 912.The operator of these participations even can be from same country.For the operator (VPMN just) of each participation, GLR902 is configured, and only makes it that route sends those transaction from the inbound roamer of HPMN, and wherein said transaction is being carried out TR and resisted these operators.In the middle of one embodiment of the present of invention, when cancelling receiving of message by first registration of initiatively monitoring between a HPMN204 and a VPMN102, and detecting HPMN204 when carrying out TR, GLR902 stores the profile of immigration roaming mobile stations 202.The profile of successful registration is stored in the time interval local and that storage can be set, upgrades to avoid the position subsequently to HPMN in VPMN, or even avoids being back to once more VPMN.

When no matter when resisting Cancel Location that VPMN carries out TR from the HLR of HPMN, GLR902 also cancels its local profile except cancelling its local profile in real VPMN VLR.Selectively, when no matter when resisting Cancel Location that VPMN carries out TR from the HLR of HPMN, as long as the time interval of setting of profile does not stop, GLR902 just cancels real VLR profile, and still roamer's profile is remained on GLR.Therefore, no matter when inbound roamer was back to VPMN before the time interval that can set stops, and inbound roamer can use the roamer's profile from GLR902, and does not upgrade with HPMN network executing location, registers.

Yet,, stop up to the time interval that can set if inbound roamer all can't receipt of call and short message service in a period of time.For fear of this situation, in the middle of an alternative embodiment of the invention, after the inbound roamer that returns is successfully by the GLR902 registration, GLR902 continues pseudo-LUP message (that is one or more registration message from a VPMN102) is distributed to HPMN, upgrades successfully up to the position.This puppet LUP message is sent out according to global title, and wherein said global title is corresponding to inbound roamer present located VPMN network.Because mobile phone is registered, so GLR902 can issue each continuous pseudo-LUP message on the time interval that can set arbitrarily, and needn't worry mobile phone state.Therefore, the HPMN network will can't be distinguished between renewal of GLR position and the renewal of real inbound roamer position.In the middle of a specific embodiment of the present invention, the GLR902 unit can outside the ITR and within independent utility.

Has the inbound traffic redirection that stops competitor ITR

Figure 10 has shown that according to specific embodiments of the invention execution ITR attempts checking the flow chart from the ITR trial of competitor's network.In this embodiment, except ITR module 226 is configured in a VPMN102, the situation that the ITR module also is configured in the 2nd VPMN104 also is considered.Attempt when a VPMN102 registers when immigration roaming mobile stations 202, a VPMN102 is sent to HPMN HLR210 with LUP message 1002.Afterwards, HPMN HLR210 is sent to Cancel Location message 1004 VLR of the 2nd VPMN104.ITR module in the 2nd VPMN104 is sent to HPMN HLR210 with pseudo-LUP message 1006.Afterwards, HPMN HLR210 is sent to a VPMN102 with LUP termination/system failure message 1008.One receives error messages 1008, and the ITR module can be inferred the existence in another ITR module of the 2nd VPMN104.Therefore, in order to stop ITR to attempt from competitor VPMN (VPMN104 just), ITR module 226 sends pseudo-LUP message 1010 continuous 3 times or 4 times, the ITR mechanism that stops the competitor, and when cell phone is just being attempted another position when attempting, mobile phone is in manual mode or the 2nd VPMN does not cover because competitor ITR mechanism is perceived, and the transaction that then will have success is recorded in HPMN HLR210, and has therefore avoided the ITR from the competitor.

Computer software application

Computer usable medium provided herein comprises computer usable program code, this computer usable program code is when carrying out, by one receive at a described VPMN place from one or more registrations cancellation message of HPMN the first registration cancellation message time, just detect may the changing of registration of described immigration roaming mobile stations, and be controlled at the communication of the immigration roaming mobile stations between a VPMN, the 2nd VPMN and the HPMN.This computer usable medium further comprises and is used for the computer usable program code of attempting to be redirected, the described computer usable program code that is used for attempting to be redirected is after one or more registration cancellation message of receiving from described HPMN, by one or more registration messages are sent to described HPMN from a described VPMN, this code is just attempted described communication redirection to the VPMN.For each registration of receiving cancellation message, one or more registration messages are sent out in (T0) at interval at first Preset Time, are registered as the transaction of success up to a registration message.Further, for one or more registration cancellation message of receiving in the current trial that described immigration roaming mobile stations is redirected to a described VPMN, described one or more registration messages are sent out in second Preset Time interval (T1) and/or under the threshold number of setting up new registration procedure at least.

Inbound traffic redirection system (ITRS) can be used for limiting by VPMN operator because the signal of the bad luck of described VPMN operator covers or blind spot, and the inbound roamer that just desiring of attempting to register under competitor's network leaves.This inbound traffic redirection system (ITRS) can also be utilized by VPMN operator, has disposed communication redirection and checks VPMN operator or use the HPMN operator that the request of the TR method of non-biddability is refused disclosing HPMN operator to resist those.In other situation, ITRS can be used for stoping the possible ITR from competitor VPMN network to attempt by VPMN operator.In other words, ITRS can also be used to stop the immigration roaming communication to the leakage of carrying out the competitor operator of inbound traffic redirection.The roaming profiles of the inbound roamer that this system also can register success carries out buffer memory, and the communication redirection of avoiding HPMN operator subsequently or competitor VPMN operator to carry out, wherein this HPMN operator or competitor VPMN operator have disposed communication redirection with antagonism VPMN operator.The context of detection of this ITRS also will help VPMN operator to prepare commercial the impact and the rescue behavior.
