Background of invention
Background technology
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 are to their travel abroad user and go sight-seeing their area and use the visitor of their external mobile phone that international roaming is provided.In in recent years, due to the price pressure that competition strengthens and brings thereupon, Virtual network operator is to the income continuous decrease from local user.On the other hand, in the same period in, the mobile infiltration of being on the increase due to local market and the increase of tourism, from roamer's income sustainable growth.Various Virtual network operator prefers mutual bilateral roaming agreement (affiliate), and this bilateral roaming agreement comprises more favourable wandering fee than non-Partner operator.Therefore, " preferably " visited network is that those are worked as roamer and travel to while exceeding local network overlay area, and local network is recommended the network of its departure roamer registration.Non-partner network is " not preferred ".
If roamer roams under preferred (or affiliate) network of their local mobile operator, the maximum revenue that Virtual network operator can be to them, and roamer can obtain more attracting wandering fee and service.When user roams into visited network from HPMN, 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 preferred ".Therefore, protect existing roaming income, and further increase the top priority that they have become global network operator.Yet the method for controlling at present the network of registration when user roams has some shortcoming.
HPMN operator is used communication redirection technology in their network, hinders their user's mobile phone and roams under the VPMN of " not preferred " network.Sometimes HPMN operator can be controlled at by communication redirection technology the distribution of the departure roamer between the VPMN network in country, so that the VPMN network of " preferably " will obtain very a high proportion of HPMN roaming communication, and the VPMN network of " not preferred " will obtain the HPMN roaming communication of low ratio.Those communication redirection technology of being used by HPMN operator can be deprived the immigration roaming income of not preferred VPMN operator.Sometimes these VPMN operators can have partnership relation with HPMN, and are even likely the networks of " preferably ".Further, the network error information that be based upon that refusal is made mistakes, the communication redirection in overtime or termination techniques has produced the wave point of cell phone.The generation of those error messages forces cell phone again to start a large amount of registration attempts.This can be so that the overload of the network interface between HPMN and VPMN.
The in the situation that of having over Liang Ge VPMN operator in a country, some competition and VPMN network " not preferred " also they terminal configuration the communication redirection of certain form, by the network that stops them to spill them, keep inbound roamer.This has caused reducing for the income of other VPMN operators.For these VPMN Virtual network operators, it is disadvantageous abandoning user's control, even when mobile phone for example, has started the registration attempt under not preferred network with any reason (SIM network directory produces the failure of registration under preferred network).
Due to above-mentioned one or more problems of mentioning, in this area, departure communication redirection need to check in HPMN operator, and inbound traffic redirection need to check in the VPMN operator of competition.

Stop TR system
Fig. 1 has shown according to specific embodiments of the invention, the system 100 that the communication between the local Public Mobile Network (HPMN) 102 of roaming mobile stations 106 and access Public Mobile Network (VPMN) 104 is controlled.When roaming mobile stations 106 (or roamer) is roamed away from HPMN102, this roaming mobile stations 106 (or roamer) is connected to Visited Location Registor (VLR) 108 places of the VPMN of VPMN operator.In the middle of one embodiment of the present of invention, the mobile switching centre that is interviewed (VMSC) in VPMN VLR108 and VPMN104 integrates, although can there be different logical addresses in VPMN VLR108 and the mobile switching centre that is interviewed.Files on each of customers (profile) data corresponding to roaming mobile stations 106 are stored in the attaching position register (HLR) 110 of HPMN.Corresponding to the signaling utilization of roaming mobile stations 106 in the international signaling transfer point 1 (STP1) 112 at VPMN104 place with in the international signaling transfer point 2 (STP2) 114 at HPMN102 place and be sent out.Signaling between HPMN102 and VPMN104 is utilized Signaling System 7(SS-7) (SS7) architecture 116 and is transported.The signal exchanging between HPMN102 and VPMN104 is the signal based on MAP (movement should part).VPMN VLR108 interacts by the international STP1112 of switch 118Yu.In the middle of an example of the present invention, switch 118 is the roaming STP in VPMN104.
Communication corresponding to roaming mobile stations 106 is redirected by the operator in HPMN102, roaming mobile stations 106 is controlled to preferred (or or even not preferred) Virtual network operator in VPMN104.In other words, communication redirection (TR) is carried out by the operator in HPMN102, by the communication redirection of roaming mobile stations 106 to other Virtual network operators in VPMN104, even the operator in HPMN102 can with VPMN104 in the operator of locking have roaming to contact.The controlling of roaming mobile stations 106 deprived the income that the operator that is blocked in VPMN104 obtains from inbound roamer there.This system 100 comprises and stops TR module 120, and this stops communication between TR module 120 monitoring HPMN102 and VPMN104 to detect TR attempt, and after the TR that provides necessary message to stop to be detected attempt.In example of the present invention, stop TR module 120 to be configured by (or bereft) operator of these lockings in VPMN104, the TR attempt of being attempted to carry out by the operator in HPMN102 is stoped.This prevention TR module 120 comprises TR detector 122 and stops TR unit 124.In the middle of example of the present invention, stop the signaling of the exchange between the international STP1 112 of the TR module 120 switch 118He of monitoring in VPMN104.This passive monitoring that is called.In the middle of another instantiation of the present invention, stop TR module 120 active interception from the signaling of switch (or roaming STP) 118.Further, switch 118 is configured, and makes it aid in HPMN102, stops at least one enrollment response message between TR attempt unit 124 and TR detector 122 and the exchange of one or more registration messages.Therefore, TR detector 122 is stoping TR module 120 interior to the monitoring of TR attempt or survey in two ways and carry out, passive or or monitor on one's own initiative the signaling between HPMN102 and VPMN104.These two kinds of patterns are in conjunction with Fig. 2, Fig. 3 and Fig. 4 and explained respectively.
Detect the system of HPMN communication redirection
In the middle of an alternative embodiment of the invention, TR detector 122 is by checking at least one the reception in one or more one or more error messages from HPMN102 and one or more success message, so that the one or more enrollment response message from VPMN104 are made to response, and detect described TR attempt.TR detector 122 can only receive the error messages for all LU (position renewal) message being sent by VPMN104 (for example LUACK (position is upgraded, and confirms) error messages) from the gateway of HPMN.In this case, can to infer that HPMN104 is communicating towards VPMN104 redirected for TR detector 122.In the middle of an alternative embodiment of the invention, TR detector 122 is at the upper LU ACK error messages (such as the system failure, unexpected data value, termination and missing data parameter etc.) receiving from each message in four of VPMN104 continuous LU message of same HPMN inbound roamer (meaning is roaming mobile stations 106).In this case, TR detector 122 can infer that the HPMN102 VPMN104 that conflicting communicates redirected.
In the middle of an embodiment more of the present invention, TR detector 122 N time at first (for example N=1), rather than on HPMN roamer, receive " roaming do not allow " next time, or " owing to not supporting the roaming restriction of characteristic ", or the error messages of " due to the signing roaming restriction in area ".Can infer that the HPMN102 VPMN104 that conflicting communicates redirected attempt.In the middle of an alternative embodiment of the invention, TR detector 122 is received by phased manner this error messages and this success message (for example LU ACK message) on the inbound roamer of same HPMN within the time interval (the T time interval) of setting.In the middle of one embodiment of the present of invention, T is 24 hours periods.In this case, TR detector 122 also infers that the TR being carried out by HPMN102 attempts.In the middle of an alternative embodiment of the invention, TR detector 122 detects TR attempt when error messages is greater than setting limit (TS) to the ratio of success message.Exemplary limit value is 10%.
The monitoring mode that stops TR
Fig. 2 has shown according to specific embodiments of the invention, the flow chart of the method that the communication between the HPMN102 of roaming mobile stations 106 and VPMN104 is controlled.In this embodiment of the present invention, stop TR module 120 by the signaling of passive monitoring (monitoring mode) between HPMN102 and VPMN104, detect TR attempt.In step 202, for the TR attempt of roaming mobile stations 106, by the exchange of at least one registration message between HPMN102 and VPMN104 of passive monitoring, and be prevented from TR module 102, detect.In the middle of example of the present invention, TR detector 122, by observing the exchange of at least one registration message between HPMN102 and VPMN104, is attempted and this TR detected.In the middle of this example of the present invention, the LU refuse information of attempting to start TR that described at least one registration message is sent by HPMN102.This LU refuse information can comprise TR refusal error messages or abort message.This LU refuse information is the signaling message based on MAP (MAP), should be prevented from 102 detections of TR module by the signaling message based on MAP (MAP).LU refuse information is sent by HPMN102 the TR starting for roaming mobile stations 106 and is attempted.
In step 204, stop TR module 120 in response to the LU refuse information on roamer's (meaning is roamer's platform 106), and on same roamer, send one or more LU message, stop TR attempt.Described one or more LU message represents roaming mobile stations 106 as one or more enrollment response message and is sent out.In the middle of one embodiment of the present of invention, stop TR unit 124 by sending one or more enrollment response message to make response to receiving at least one registration message of self-exchange machine 118, and stop TR attempt.Described one or more LU message is sent to HPMN102 to be greater than predetermined number of times.In the middle of a specific embodiment of the present invention, pre-determined number is four times.Before roaming mobile stations is sought other VPMN, this roaming mobile stations sends four LU message corresponding to VPMN.Therefore,, in order to allow HPMN102 stop TR attempt, stop TR unit 124 to represent that roaming mobile stations 106 is sent to HPMN102 by three LU message.These LU message are pseudo-LU message, and are sent out after roaming mobile stations has sent first LU message.After this, roaming mobile stations 106 sends second LU message, makes the LU message sending at HPMN102 add up to five.Therefore, HPMN102 is forced to suppose roaming mobile stations 106 or in manual mode, or in the country of VPMN104, does not have other operator to be connected by roaming mobile stations 106.As the result of this attempt, HPMN102 has permitted the connectedness to roaming mobile stations 106 with VPMN104.
Common another transaction just being formed by LU message and LU refuse information corresponding thereto of expense that stops the signaling of TR module 120 generations.Upgrade and compare with complete position, this seems unimportant, and wherein this position is upgraded and comprised MAP LUP (MAP, position is upgraded) and MAP ISD (in MAP, inserting user data) request and their response.Therefore, this has also reduced the signaling between HPMN and VPMN.At a specific embodiment of the present invention, work as, stop TR unit 124 to represent that roaming mobile stations 106 sends a pseudo-LU message, to allow roaming mobile stations 106 that remaining LU message is sent on himself.In the middle of this embodiment of the present invention, after primary TR attempt is detected by TR detector 122, stop TR unit 1 24 within the time interval of setting, to send pseudo-LU message subsequently.Pseudo-LU message can be sent out between any two TR refusal, and wherein this TR refusal is corresponding to the LU message from roaming mobile stations 106.So do is in order to stop TR to detect (or defence) system at HPMN102 place.Further, the method also forces HPMN102 using roaming mobile stations 106 as mobile phone dedicated and perception, and therefore permits connecting.
Interior signaling (IN-SIGNALING) pattern that stops TR
Fig. 3 and Fig. 4 have shown according to specific embodiments of the invention, control the flow chart of the HPMN102 of roaming mobile stations 106 and the method for the communication between VPMN104.In the middle of this embodiment of the present invention, stop TR module 120 to detect TR and attempt by initiatively monitoring signaling between HPMN102 and VPMN104.In step 302, for the TR attempt of roaming mobile stations 106, by initiatively monitoring the exchange of at least one registration message between HPMN102 and VPMN104, and be prevented from TR module 102, detect.Below, initiatively monitor the interchangeable interior signaling mode that is considered to.Under interior signaling mode, by the switch 118 (or roaming STP) of configuration VPMN104, stop TR module 120 to be configured on roaming SS7 path with forwarding country internet roaming SCCP (SCCP) communication through stoping TR module 120.In other words, switch 118 is configured to assist at HPMN102 and stops one or more described enrollment response message between TR module 124 and the exchange of at least one registration message.
In step 304, stop TR module 120 to represent that roaming mobile stations 106 sends one or more enrollment response message and stops TR attempt.In a specific embodiment of the present invention, stop TR unit 124 by sending one or more enrollment response message, to make response to receiving at least one registration message of self-exchange machine 118, and stop TR attempt.In exemplary route, lead to the main road of the international SCCP communication entering of E164 address of VPMN104 of VPMN VLR108 by being configured, with by stoping TR module 120.Yet secondary route is held VPMNVLR108.So doing is for redundant path being provided to the route of communication, in case stop TR module 120 to break down.Similarly, the main road of the international SCCP communication of the outgoing of the E214 address of the HPMN102 of any HPMN of being sent to HLR110, by being configured, stops TR module 120 to pass.Yet this secondary route passes to international STP2 114.To those skilled in the art, obviously, not affecting under the working method of system or method, can apply different method for routing.Another kind of route technology is described in conjunction with Fig. 5.
E214 is for transmitting the numbering plan (NP) of mobile management related news under GSM network.E214 number is the IMSI that is derived from roaming mobile stations, and is comprised of two parts.First, E164 part is comprised of country code and the network code of following thereafter.The second portion of number is comprised of subscriber identity code (MSIN) part of IMSI, and this MSIN partly identifies independent user.E.214 number is to separate transmission with number E.164, because they have different numbering plan indicating devices (NPI).Yet, except the final purpose network of message, can recycle throughout global title (GT) analytical table (analysis table) in number E.164.
Use the prevention TR route of map table (TT)
In the situation that the address of VPMN VLR and VMSC is identical, SubSystem Number (SSN) can be used for disjoint route.For ability, for technical staff, apparently, depend on the network type in VPMN104, other Route Selection is also feasible.For example, for fear of circulation, depend on the network architecture in VPMN104, communication redirection can or utilize map table (TT) and carries out, or utilize message transfer part (MTP) route and carry out, this MTP route comprises international STP, and the international STP of Bing Jianggai is as destination end coding (DPC).With reference to Fig. 1, and consider to use TT before technology, switch 118 and stop TR module 120 to be configured, for that enter and international SCCP signaling message outgoing.For example, for the message that enters at switch 118, the TT of this message is 0, and called party address (CdPA) is not self, and E.214 numbering plan (NP) be, DPC is set as stoping TR module 120.Similarly, if CdPA is VPMN VLR108, and TT is 0, and DPC is configured to stop TR module 120 so.This means that first any E164 message entering at switch 118 be directed to prevention TR module 120.In the outgoing message from switch 118, TT is 32, CdPA is not oneself and NP in situation E.214, DPC is set as international STP1 112.Further, if TT be 32 and CdPA as VPMN VLR108, DPC is also set to VPMN VLR108.This means any from switch 118 and be received from and stop the outgoing message of TR module 120 (because TT is 32) to be directed to the address in CdPA.Further, use TT as 32, any outgoing message from stoping TR module 120 has its DPC, and this DPC is set as switch 118.Route indicator in all these situations (RI) is the global title (GT) of VPMN VLR and/or VMSC.
Do not use the prevention TR route of TT
Consider to use the second technology of MTP route, switch 118 is configured to be sent to by entering message the DPC that stops TR module 120, wherein this NP as E.214 and CdPA be not oneself.And in the situation that CdPA is VPMN VLR108, DPC is transformed into and stops TR module 120.Therefore, any message that enters at switch 118 is all sent to prevention TR module 120.Stoping the route setting of the input message of TR module to be set to VPMN VLR108 with DPC, and using RI as SubSystem Number/do not change.Similarly, for the outgoing message that certainly stops TR module 120, DPC is set as international STP1112, and using route indicator as global title (GT).Different entering and outgoing message based on from switch 118, stops TR module 120 that different message is sent as one or more enrollment response message, to stop TR attempt.
Detect HPMN TR
In the middle of a specific embodiment of the present invention, TR attempt is by checking at least one or more reception from the error messages of described HPMN, and/or the reception of one or more success messages from described HPMN, so that one or more enrollment response message are made to response, and detected by this HPMN 102.Error messages is the LU refuse information that HPMN102 sends, so that the LU message that stops TR module 120 to send is made to response.Similarly, one or more success messages are the LU ACK message that HPMN102 sends, so that the LU message that stops TR module 120 to send is made to response.In the situation that LU ACK error messages (such as the system failure, unexpected data value, termination, missing data parameter etc.) is sent to four continuous LU message on same HPMN roamer (meaning is roaming mobile stations 106), stop TR module 120 TR attempt also can be detected.Only LUP ACK is made mistakes and is back to roamer observing HPMN GT, but never success message is back in roamer's situation, stop TR module 120 TR attempt also can be detected.Stop TR module 120 TR attempt can also in following situation, be detected, the error message of " roaming do not allow " or " owing to not supporting the roaming restriction of characteristic " or " due to the signing roaming restriction in area " is for example, at N time at first (N=1), but is not the LU message being next time sent to from the same HPMN roamer of VPMN.Stop TR module 120 TR attempt can also in following situation, be detected, the error messages on same roamer and success message are intermittently sent within the time interval (T) of setting.In the middle of example of the present invention, T is the cycle of 24 hours.Further, stop TR module 120 TR attempt can also in following situation, be detected, error messages has surpassed and can set threshold values (TS) the ratio of success message.Exemplary TS value is 10%.To those skilled in the art, apparently, for detection of the various embodiments of HPMN communication redirection, under monitoring mode and interior signaling mode, all can apply.
From 306 to 314 method step has shown based on accepting change planes 118 different messages of selfing, has stoped TR module to stop the various different embodiment of TR attempt.It will be appreciated by those skilled in the art that one or more said method steps (from 306 to 314) can independently be carried out mutually or any combination stops TR attempt.
Stop HPMN TR
In the middle of a specific embodiment of the present invention under active monitoring mode, in step 306, stop TR module 1 20 to switch 118, to send one or more LU message by representing roaming mobile stations 106 and stop the TR being detected to attempt, wherein this switch 118 turns biography (relay) to HPMN102 by those message.This one or more LU message is sent out, and with the LU refuse information (be taken as at least one registration message and be received) that at least one is received to HPMN102 and is turned biographys (relay) and pass switch 118 (meaning is the roaming STP in VPMN104), makes response.It can be the mobile phone under mobile phone dedicated or manual mode that this one or more LU message forces HPMN HLR110 to perceive roaming mobile stations 106.This by sending LU message or by with for example, more than estimating that number of times (four times) sends LU message and is implemented in setting-up time interval.
In the middle of another specific embodiment of the present invention under active monitoring mode, in step 308, (mobile application is not minute by sending MAP ISD ACK to stop TR module 120, insert user data, confirm) message, so that MAP ISD message is made to response, and stop the TR attempt being detected.If the SCCP message of any outgoing carries MAP LUP message, its SCCP and TCAP (TCAP Transaction Capability Application Part) parameter is prevented from 120 records of TR module so.Afterwards, if the SCCP message entering carries the MAPISD message with the transaction having recorded, first this SCCP message entering utilized the MAP LUP message being previously recorded and by cumulative record, followed utilization and be stored in the logical program in prevention TR module 120 and be verified so.If MAP ISD message for identical transaction comprise be less than can set point number (K) roaming restriction (RR) (due to do not support characteristic or because area is signing), the MAP ISD ACK message that stops TR module 120 to have any error message by transmission is refused MAP ISD message, this error message for example: unexpected data value, service are not supported, TCAP ends or above combination.Exemplary can set point number K be 2.Therefore, HPMN is forced to believe that the network in VPMN104 is only available network at present, and wherein this available network has overlay area or the roaming mobile stations 106 of manual mode.In another case, if MAP ISD message comprises for identical transaction the roaming in Operator Determined Barring (ODB) that is less than set point number (L), do not allow (RNA), this MAP ISD message is prevented from TR module 120 and refuses in MAPISD ACK message.Exemplary can set point number L be 2.Again, HPMN is forced to believe that roaming mobile stations is manual mode.
In the middle of an embodiment again under active monitoring mode of the present invention, in step 310, stop TR module 120 by sending one or more LU message, to make response to receiving MAP LUP ACK message, MAP abort message or the TCAP abort message of self-exchange machine 118, stop TR attempt.In the first situation, when the SCCP message entering carries MAP LUPACK message, wherein this MAP LUP ACK message response to the transaction being recorded, the following a series of logical program of SCCP message utilization that this enters and being examined.In the situation that MAP LUPACK message comprises error message, will carry out following a series of operation, wherein this error message is from the identical IMSI of the identical transaction ID that starts of identical VLR/VMSC, and be less than set point number N (for example N=5), for example: the system failure, unexpected data value, missing data.
Stop TR module 120 to abandon MAP LUP ACK message, that is to say, it is not sent to message VPMN VLR108 (or message is turned and reaches VPMN VLR108).After this, can be after the time interval T1 setting, stop TR module 120 to represent the IMSI of roaming mobile stations 106, use identical parameter (the calling party address and the called party address that comprise identical VLR, VMSC address, SCCP, although may use different TCAP transaction identification), using another LU message as the LU message being recorded, start.In the embodiment of example, T1 value can be random (for example T1=0s, T1=50s or T1=300s), is detected avoiding by HPMN TR.Further, different in the situation that, stop TR module 120 that ensuing (one or more) LU message is abandoned from the IMSI of same position (VLR/VMSC) roaming mobile stations 106, namely stop TR module 120 LU message not to be sent to HPMN102, so that HPMN thinks that hand hand is mobile phone dedicated, because interaction locations interval update time of consolidated network is oversize.And in another case, if current TR refusal is the 4th time, comprising the twice LU message for stoping TR module 120 to start, stop so TR module 120 that the renewal of ensuing position is abandoned from the IMSI of (VLR/VMSC) roaming mobile stations 106 of same position, so that HPMN thinks that mobile phone is mobile phone dedicated, because interval update time, position of internet is oversize.
In another case, if MAP LUP ACK message comprises error message, for example for example, roaming in set point number X (X=2) does not allow (RNA), will carry out so the operation of following series.Stop TR module 120 to abandon MAP LUP ACK message, that is to say, it is not sent to this message VPMN VLR108 (or turn reach VPMN VLR108).Further, after the time interval T2 setting, stop TR module 120 to represent the IMSI of roaming mobile stations 106, use identical parameter (the calling party address and the called party address that comprise identical VLR, VMSC address, SCCP, although may use different TCAP transaction identification), using another LU message as the position being recorded, upgrade and start.In the embodiment of example, T2 value remains random (for example T2=0s, T2=50s or T2=300s), is detected avoiding by HPMN TR.
Yet, if the SCCP message entering is MAP abort message or TAP (the long range positioning device digital alphabet agreement) abort message of the response of the transaction to being recorded, the following serial logical program of this SCCP message utilization and being examined.For example, if the abort message for the IMSI of the roaming mobile stations 106 of the identical transaction identification that starts from VPMN VLR108 is less than set point number N (N=5), will carry out the following sequence of operation so.Stop TR module 120 abandon abort message (meaning is that it is not sent to message VPMN VLR108) or this message is turned and reaches VPMN VLR108.After this, can for example, after the time interval T1 that can set (T1=0s, T1=50s or T1=300s), stop TR module 120 to represent the IMSI of roaming mobile stations 106, use identical parameter (the calling party address and the called party address that comprise identical VLR, VMSC address, SCCP, although may use the sign of different TCAP transaction), using another LU message as the LU message being recorded, start.
When at above-mentioned all conditions all in ungratified situation, it is that TT type or MTP route are used that all SCCP message entering relies on, and can turn respectively biographys (relay), is back to switch 118 (or roaming STP) or VPMN VLR108.In above-mentioned method, SCCP, rather than TCAP is turned biography.Yet to those skilled in the art, apparently, similarly flow process (flow) also can be for passing and define based on turning of TCAP.In this case, for each new transaction from the LU message that opens, will be prevented from TR module 120 and start, and each new mapping will associate new transaction identification and the initial transaction identification that starts of starting.
According to 3GPP 29.010 standards, the error messages being received in the SCCP message entering of makeing mistakes on interface is mapped to the information that is equal on wave point.Table 1 has shown that part message maps to the snapshot of wave point (24.008) from the interface of makeing mistakes (29.002), and has the corresponding error code of each interface.
| The code of makeing mistakes | 24.008 mobile management (refusal is upgraded in position) | 29.002MAP upgrade position response | The code of makeing mistakes |

Table 1
For example, error message in the situation that make mistakes in interface " system failure " (code 34 of makeing mistakes) (29.002), error message upper at wave point (24.008) so and its equity is " network failure " (code 17 of makeing mistakes), and be received on roaming mobile stations 106, roaming mobile stations 106 is once waited for 20 seconds or 15 seconds before trial upper.Similarly, other 24.008 error messages also has 29.002 error messages of equity.
The immigration TR that stops VPMN
In the middle of an embodiment again under active/passive monitoring mode of the present invention, in step 312, stop TR module 120 by sending one or more LU request messages, with the termination of the MAP corresponding at least one VPMN to being detected or TCAP, end to make response, stop TR attempt.In the middle of this embodiment of the present invention, the competition operator attempt in VPMN104 is controlled the network to him with TR by the communication of inbound roamer.Stop TR module 120 to check whether have the SCCP message of any outgoing to carry MAP LUP message, one is checked through this MAP LUP message, SCCP, TCAP parameter and transaction are just recorded.Further, if the message entering carries MAP termination, TCAP termination or the system failure that responds the transaction being recorded, this message entering is utilized following serial logical program and is examined.
A specific embodiment is to have to be prevented from the abort message that TR module 120 abandons, prerequisite is can set point number Z if be less than for the abort message of the IMSI of the roaming mobile stations 106 of the identical transaction identification that starts from identical VLR or system failure message, Z=((N-1) * 4+1), wherein the set point of N is the sum from minimum value 2 to this national Virtual network operator.Afterwards, for abandon at every turn, after the time interval T1 setting, stop TR module 120 to represent the IMSI of roaming mobile stations, use same parameter (the calling party address and the called party address that comprise identical VLR, VMSC address, SCCP, although may use different TCAP transaction identification), the LU message that another LU message is recorded as first and starting.This has stoped any TR attempt of other any VPMN operators on his inbound roamer (meaning is roaming mobile stations 106).
Another specific embodiment is to allow abort message along its normal route to VLR.But stop TR module 1 20 will issue LU message, issue number of times is can set point number Z.Z=((N-1) * 4+1), wherein the set point of N is the sum from minimum value 2 to this national Virtual network operator.In this LU data publish, stop TR module 120 to represent the IMSI of roaming mobile stations, use same parameter (the calling party address and the called party address that comprise identical VLR, VMSC address, SCCP, although may use different TCAP transaction identification), the LU message that LU message is recorded as first.This has stoped the TR attempt of other any VPMN operators on his inbound roamer (meaning is roaming mobile stations 106).
When at above-mentioned all conditions all in ungratified situation, it is that TT type or MTP route are used that all SCCP message entering relies on, and can turn respectively, is transmitted back to switch 118 (or roaming STP) or VPMN VLR108.In above-mentioned method, SCCP, rather than TCAP is turned biography.Yet to those skilled in the art, apparently, similarly flow process also can be for passing and define based on turning of TCAP.In this case, for each, from the LU message that opens, new transaction will be prevented from TR module 120 and start, and each new mapping will associate new transaction identification and the initial transaction identification that starts of starting.
Auxiliary HPMN TR
In the middle of an alternative embodiment of the invention, stop TR module 120 in VPMN, to represent that HPMN sends one or more enrollment response message, so that the reception of at least one registration message of HPMN transmission is made to response.For this reason, stop TR module 120 by reducing the signaling expense between HPMN 102 and VPMN104, and assist HPMN in TR attempt.Stop TR module 120 to represent that HPMN102 sends message, be based upon on the basis of a series of logical programs and reduce the physical signaling between HPMN102 and VPMN104.
In the situation that the SCCP message of outgoing carries MAP LUP message, TCAP and SCCP parameter and transaction are recorded.If the message of outgoing is the message of LUP first for IMSI (or roaming mobile stations 106) in VPMN104, if or when IMSI is before after VPMN104 registration, the message of this outgoing is the message of LUP first about IMSI, stops so TR module 120 to represent that HPMN102 carries out " without operation ".Otherwise, if the operating limit of corresponding setting does not reach, stop TR module 120 message can not turned to biography (relay) to HPMN (representing HPMN102), to reduce the signaling expense between VPMN104 and HPMN102.Further, if the SCCP message entering carries the MAP ISD message of the transaction having recorded, first this SCCP message entering utilize (comprising SCCP and TCAP parameter) LUP transaction of being previously recorded and by cumulative record so, then utilizes a set of new logical program and be verified.Stop TR module 120 to check whether ISD comprises RR (roaming restriction), then represents HPMN102, stops TR module 120 oneself " RR " to be distributed to VPMN104.In the exemplary case, the setting limit of this operation can be 1.Similarly, if ISD comprises RNA (roaming does not allow) in ODB, then represent HPMN102, stop TR module 120 oneself " RR " to be distributed to VPMN104.In the exemplary case, the setting limit of this operation can be 1.
Yet, if the SCCP message entering carries MAP LUP ACK message, stop the following logic of TR module 120 use to check it.If LUP ACK message comprises any code of makeing mistakes for the identical IMSI of the identical transaction identification that starts from identical VLR/VMSC (meaning is roaming mobile stations 106), the for example system failure, unexpected data value or missing data, represent so HPMN102, stop TR module 120 oneself " code of makeing mistakes " to be distributed to VPMN104.In the situation of this example, the limit set of this operation can be 3.Similarly, if LUP ACK message comprises the code RNA that makes mistakes, represent so HPMN102, stop TR module 120 oneself will issue " RNA ".In the situation of this example, the setting limit of this operation can be 1.In addition, if the SCCP message entering carries MAP, end or TCAP abort message, represent so HPMN102, stop TR module 120 oneself will issue " termination ".In the situation of this example, the limit set of this operation can be 3.
By using GLR (Gateway Location Register) to avoid HPMN TR
In initiatively monitoring, (meaning, interior signaling paths) in the embodiment more of the present invention under pattern, in step 314, when roaming mobile stations is after the registration of VPMN104 place, by one or more archives for roaming mobile stations 106 (profile) updating message is sent to VPMN104, so that the corresponding one or more LU message from one or more VLR are made to response, and the TR attempt of HPMN102 is prevented from.In this embodiment, GLR is configured in VPMN104 and stops HPMN TR to attempt.GLR is the node between VPMN VLR108 and HPMN HLR110, and can be used to passing through network border and optimize position and upgrade and the processing of subscriber profile data is optimized.When user is when roaming, GLR plays the effect of HLR, its VLR in VPMN104, and the effect of playing VLR, its HLR in HPMN102.In other words, GLR serves as the VLR108 towards the VPMN of HPMN HLR 110, and serves as the HLR110 towards the HPMN of VPMN VLR108.In general, it turns a LU message to reach HPMN HLR110 from inbound roamer (roaming mobile stations 106), and stores user data archives.In the VPMN104 of roaming mobile stations 106 under different VLR/VMSC, move everywhere, for mutual VLR position subsequently, upgrade, GLR self sends file data and position is not upgraded to turn and reach HPMN HLR110, the TR attempt of therefore avoiding HPMN102 to initiate.For fear of being detected by HPMN TR, on the roamer that GLR upgrades in the position for subsequently, random selection carried out position renewal, even if files on each of customers is stored by locality.In the middle of another example of the present invention, GLR and the 120 integrated settings of prevention TR module.The TR of prevention based on OTA (downloading in the air)
Initiatively monitoring in the embodiment more of the present invention under (signaling paths this means) pattern, in step 314, stop TR module to be ended or TCAP refuse information by sending TCAP, so that OTA TR message is made to response, stop TR to attempt.In this case, HPMN102 carries out TR attempt by sending OTA message, and wherein this OTA TR message can be note.Stop TR module 120 to check whether OTA TR message can affect network reselection.If OTA TR message is for TR attempt, stop TR module 120 to send the TCAP refuse information with any error message, this error message for example do not support by service/device, unexpected data value, the system failure or resource limitation etc.In another kind of situation, the TCAP that stops 120 transmissions of TR module to have unknown cause or reason ends, and this unknown cause or reason be " transaction portion of error format " " incorrect transaction portion ", " resource limitation " or its above combination for example.In addition, when in fact stoping TR module 120 to omit HPMN OTA TR message, meaning be it while this message not being turned to the VMSC VLR108 reaching in VPMN104, stop TR module 120 can only confirm to HPMN102 the success of OTA TR message.
Whether in order to detect SCCP message, is OTA TR message, first this message need to be construed to is MAP MT/Fwd (in MAP, mobile terminal/forwarding) note.Secondly, the SM-RP-UI of this note (note-trunk protocol-user identifier) then needs by approval, SIM data to be downloaded to the protocol-identifier that is used as it, and is had UDHI (User Data Header indication) field by approval.The user data fields that SM-RP-UI Parametric Representation is carried by short message relaying sublayer agreement.It is function that SIM data are downloaded, and mobile device must be by being used the mechanism of describing in GSM11.11 that short message integral body is passed to SIM whereby, and wherein this short message integral body comprises all notes unit in note transmission.Data coding scheme (DCS) will be set to (class 2) 8 message (position is encoded to 1,111 0110 or 00010110) of 2 classes.Whole user data fields is downloaded all available for SIM data.Therefore, the OTA TR message that stops TR module 120 to get rid of for mobile phone, for example, allow WAP and MMS (MMS) to arrange.If unencrypted words, short message content is organized digestion and observes whether comprise any OTA user data.If comprised, next step this short message is examined user data and whether comprises the modification that network is selected associated documents.These files can comprise network of preferred PLMN catalogue, finally registration etc.These parameters can dynamically be controlled by configuration.Modification in data can be transferred into STK (sim card development kit) application.Because most of OTA message is based upon on GSM348 encrypted, whether SMS-RP-UI UDH (User Data Header) part that can check note comprises some parameter in command header the inside, and wherein these parameters are defined within (table 2 has shown part extracts wherein) in GSM348.

Table 2
For example, if the SMS-RP-UI UDHI of short message partly comprises order data Packet Identifier or command identifier, the SMS-RP-UI UDHI of this short message part can be taken as the OTA message of SIM resident application and process.If the kit application reference of the command header being encoded in the GSM348 of note UDH field (Toolkit Application Reference) is considered for the TR application based on some intelligent logical, short message can be identified as the OTA message that TR is relevant more accurately so.
Some exemplary intelligent logical can be learnt from having disposed TR based on OTA or the operator of close beta there, thereby come acknowledge message whether to move the network of roaming mobile phone.
According to GSM348
Quote:
If order data packet length surpasses 140 eight bit bytes (comprising command header), this command packet will be linked according to GSM03.40.In this kind of situation, the whole command packet that comprises command header will be incorporated into together, then be split on its element chain matrix section.The first note will not comprise link User Data Header and order data Packet Identifier with specific order in UDH.Note subsequently will only comprise link User Data Header.This chain joint comprises reference number, and this reference number links together permission receiving entity and individual note, makes before opening order data report, by the combination of again collecting of initial command packet.
End is quoted.
This means when stoping TR module 120 an OTA TR message of link to be detected, stop TR module before decision takes any action, wait for that the OTA TR message subsequently of same reference number is carried out the whole message of reconstruct.Selectively, can adopt rule to process any short message as OTA TR message, if they have protocol-identifier, as SIM data, download, and there is UDHI.Yet, when local operator has some and is not used in the STK application of TR in SIM, for example call manager application, those application rely on some download of the SIM data from local operator when mobile device carries roaming, and in this case, this rule is unsatisfactory.
Do not use the prevention TR based on OTA of map table
The route of the message based on OTA can also be carried out by two kinds of technology, based on map table and MTP route (or not using map table).With reference to figure 1, and consider based on map table technology.Switch 118 and prevention TR module 120 are configured to as OTA signaling message that enter and outgoing.For example, if having map table in the message entering of switch 118 is 0, called party address (CdPA) is as VPMN VMSC, calling party address (CgPA) is as the HPMNCC NDC (the domestic object code of national code of HPMN) that violates OTA, and numbering plan is for E.164, and DPC is set to and stops TR module 120 so.Similarly, if CdPA is that to have TT be 32 VPMN, DPC is set to VPMN VLR108.Further, any from stoping TR module 120 to use the message of the outgoing that TT is 32 to there is the DPC that is set as switch 118, and using RI as GT.
Do not use the prevention TR based on OTA of map table
Consider to use the first scheme of MTP route (namely not using TT), in the message entering of switch 118, having map table is 0, called party address (CdPA) is as VPMN VMSC, calling party address (CgPA) is as the HPMN CC NDC (the domestic object code of national code of HPMN) that violates OTA, and numbering plan is for E.164, and DPC is set to and stops TR module 120 so.For stoping the routing configuration of the message entering of TR module 120 that DPC is set as to VPMN VLRVMSC, and RI does not change as SSN/.
Fig. 5 has shown according in specific embodiments of the invention, the flow chart of the route of the signaling message between VPMN104 and HPMN102.This embodiment shows between VPMN VLR108 (in VPMN104) and HPMN HLR 110 (in HPMN102) by stoping the route of the signaling message of TR module 120.E.214 the destination message of outgoing is redirected and through stoping TR module 120.Yet, be only that the destination message of the prevention TR module that enters will be through stoping TR module 120.When the E214 of roaming mobile stations 106 message is sent to HPMNHLR110 through prevention TR module 120, the calling party address of SCCP is modified to the GT that stops TR module 120, and does not change VLR parameter.Similarly, for going to the return messages that stop TR module 120, CgPA is made into the GT corresponding to the prevention TR module 120 of HPMN HLR110.This route has advantage, because for all E.214 message of going to HPMNHLR110 through stoping TR module 120, only has those message relevant to LU transaction to have the return messages that send through stoping TR module 120.Other are message E.214, and for example Activate SS (supplemental services), inquires SS etc., be prevented from TR module and dredge along separate routes (this means, calling address keeps not changing), so return messages will be through stoping TR module 120.Further advantage is, for the international message entering of all VPMN of going to VLR108, only has those message with the called address that stops TR module 120 to be sent to and stops TR module 120.So unnecessary (request or response) message entering, for example MT shifts short message (if VLR is identical with VMSC, and SSN can not be used to distinguish VLR/VMSC route), remove short message, part in the future user's business process (for example SS service) message, can not be sent to and stop TR module 120.
Here also provide computer usable medium, it comprises control type computer usable program code, and this program code, when operation, is attempted and the communication between HPMN and VPMN is controlled by detecting for the communication redirection (TR) of roaming mobile stations.The exchange of TR attempt at least one registration message between VPMN and HPMN by observation is detected.This computer usable medium further comprise for computer usable program code, be used for stoping TR attempt.
Stop the TR Redirectional system (ATRS) to be utilized by VPMN operator, so that those have been disposed the HPMN operator that request that communication redirection checks VPMN operator refuses and resisted disclosing them.This system can be also the buffer storage of the roaming archives of the inbound roamer of successfully registering, and avoids the communication redirection that HPMN operator carries out subsequently, and wherein this HPMN operator deployable communication is redirected with antagonism VPMN operator.ATRS can also be used to stop immigration roaming communication to the leakage of carrying out the competition operator of inbound traffic redirection.Although VPMN operator does not adopt the technology that checks, for detect HPMN operator whether ongoing communication reset that always to resist VPMN operator be of great use.This detection is carried out business by help VPMN operator and is impacted preparation and rescue behavior.
