Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
The present invention mainly is the variation of determining user state information by HLR, and the operation flow of transformation HLR, realization is to the tracking report of designated user state information, comprise the report to information such as customer position information and on-off states, report manner can adopt multiple modes such as real-time short message report.
According to the mobility protocol standard of standard,, when mobile device start or mobile subscriber roaming takes place are caused position change, all to carry out location registers such as gsm protocol standard and CDMA protocol specification.Such as, when the mobile subscriber strides the roaming of MSC/VLR, MSC/VLR can report to HLR with user's current position information by location registers message, and current location information can comprise the sign of the current place MSC/VLR of user and the sign (CELLID) of sub-district, the current place of user.When the user carried out power-off operation, MSC/VLR can report to HLR with user's off-mode by deexcitation message.Therefore, HLR can obtain user's latest state information, such as current location information, on-off state information.In the CDMA protocol specification, location registers message is REGNOT (Registration Notification), and user's deexcitation message is MSINACT (MS Inactive).
The tracked state of user information that is obtained for HLR can be reported, the present invention is provided with following function in HLR:
(1) in HLR, increases the tracking type of service, the business of following the tracks of is managed, comprise that professional contract/the going of tracking contracted, activation by HLR.
Wherein, follow the tracks of the professional business that is meant to knowing that in real time user state information is followed the tracks of and reported user state information.To manage other benchmark service identical with HLR, and HLR can professional contract/going be contracted to following the tracks of, the activation state manages.In general, the signatory state that contract/goes of usertracking business is controlled by operator, and the activation state of usertracking business can be controlled by operator, also can be controlled by the business operation of standard by user oneself.Such as carrying out passive tracking, promptly non-user's a certain side itself requires to follow the tracks of under the situation of a certain designated user, can follow the tracks of professional activation state by operator's control; Follow the tracks of carrying out active, promptly the user wishes own state information to be sent to the someone or send under the oneself situation, can be controlled by user oneself, and special business operation sign indicating number activates or deexcitation tracking business such as being dialed by user itself.
(2) provide status report by HLR, status report can adopt the mode of the report that sends SMS message or HLR internal alarm mode or HLR directly transmit the report manner or the aforesaid way of combination from information to the third party.The mode of status report can be selected when activation trace is professional, also can revise later on.
For the mode that sends SMS message, in existing standard mobile network, the protocol function of HLR is the static traffic CAMEL-Subscription-Information and the dynamic location status information of recording user, and HLR can not send SMS message.Therefore, the present invention increases the function that sends SMS message for HLR, such as a functional module that can produce and send SMS message can be set in HLR.In the CDMA protocol specification, can increase the function of the point-to-point transmission of short message (SMDPP, the SMS Delivery Point ToPoint) message of transmission standard for HLR, like this, will finish following operation by HLR:
Is standard short message code stream with the initial content of short message of text formatting according to normative translation, forms the BearData parameter of SMDPP message; Recipient's Subscriber Number of appointment is set to the MDN parameter of SMDPP message; The SMDPP message that assembles is sent to short message service center (MC) according to standard mode.
After the short message that HLR sends is received by short message service center, the short message of receiving is sent to the user of appointment according to standard short message transmission flow.In the short message report manner, can set the transmission destination of short message by operator or user itself, sending the destination can be third-party mobile number, also can be user's mobile number itself.
For HLR internal alarm mode, because in the prior art, each telecommunication apparatus all possesses alarm function, be about to the function that situation of equipment own and service condition report to the Operation and Maintenance personnel, just different vendor's device processes mechanism can be different.Therefore, existing HLR can carry out internal alarm.
HLR directly can comprise by communication interface transfer mode or EMAIL mode to the mode that the third party transmits information.Wherein, be meant the third party who user state information is passed to appointment with the file transporter system between the industry general calculation machine outward by the communication interface transfer mode, such as directly utilizing file transfer protocol (FTP) (FTP, File Transfer Protocol) or utilizing socket (SOCKET) user state information to be passed to the third party of appointment.Wherein, the third party can be computer user's terminal or the service process platform that needs user state information arbitrarily.If transmit in the EMAIL mode, then need in HLR, will need the user state information of unofficial biography to generate EMAIL, then the EMAIL that is generated is passed to the recipient of appointment.
(3) conversion table in configuration is netted in HLR between device coding and the actual geographical location information is translated as the geographical location information that is more readily understood with coding in the obscure relatively nets such as MSCID/VLRID/CELLID, such as certain province city district.
The present invention is provided with in HLR on the basis of above-mentioned functions, and the business software logic among the HLR is made amendment, and with realization the tracked state of user information that HLR was obtained is reported.
Be example with the CDMA protocol specification below, illustrate that HLR of the present invention outwards reports the method for user state information, and emphasis is described the flow process by the short message way reporting state information.
At first roaming into another one MSC with certain mobile subscriber (MS) from a MSC is example, illustrates that HLR of the present invention outwards reports the method flow of customer position information.Fig. 1 reports the method flow diagram of an embodiment of user's roaming position for the present invention.Wherein, MSC2/VLR2 is the position of user before roaming, and MSC1/VLR1 is the position of user after roaming.
As shown in Figure 1, the present invention may further comprise the steps the method for reporting of user's roaming position:
After step 101, MS roamed into MSC1/VLR1 from MSC2/VLR2, according to standard agreement, MS initiated position updating request (REGREQ) to MSC1/VLR1.
After step 102, MSC1/VLR1 receive position updating request, send location update message (REGNOT) to the HLR of MS ownership.
After step 103, HLR receive location update message, find that the MSC1/VLR1 that comprises in the location update message is different with the MSC2/VLR2 of database Central Plains preservation, then send canceling position message (REGCANC) to MSC2/VLR2.
After step 104, MSC2/VLR2 receive canceling position message, this user profile of preserving in the delete database, and to HLR home position cancellation response message (regcanc).
After step 105, HLR receive the canceling position response message that MSC2/VLR2 returns, user's current location information is saved in the database, and is included in the position according to standard agreement every service profile that the user is current and upgrades in the response message (regnot) and be handed down to MSC1/VLR1.Wherein, user's current location information includes but not limited to following information: the MSC sign (MSCID) at user place, the VLR sign (VLRID) at user place, the cell ID (CELLID) at user place etc.
After above-mentioned location registration finished, if HLR finds that this MS is signatory and activated the business of tracking, then HLR can be according to the status report mode of default, real-time report user position information.Report content can be set by operator, can be including, but not limited to following information: tracked Subscriber Number, current time, current location information and original position information etc., positional information wherein can be that the geographical location information after MSCID/VLRID/CELLID or the translation is described, such as certain province city district.Before reporting, user state information can be comprised information composition normative text information (TXTData) such as tracked Subscriber Number, current time, original position information, current location information.In addition, if the HLR recording user was in off-mode originally, also user's start operation can be covered in the report content.
Report manner can be including, but not limited to following mode:
1) internal alarm mode: HLR utilizes original alarming processing mechanism, and the status information reporting that the user is up-to-date is given alarm subsystem, finishes trace flow then.
2) give the third party by communication interface or EMAIL: HLR passes to the third party with state information by interface or EMAIL, finishes trace flow then.
3) short message report manner: HLR sends to MC with user state information and the short message receiving debit number that sets by SMDPP message.
If adopt the short message report manner, then continue to carry out following steps:
Step 106, HLR require coding with the TXTData content according to standard agreement and are kept in the MS BearerData parameter in the SMDPP message; Short message receiving debit number is set at the MDN parameter of SMDPP message; Utilize SMDPP message that short message is sent to MC.
After step 107, MC receive this short message, return short message to HLR and receive response message (smdpp), whether correctly received short message with feedback.
Step 108, MC send to this short message according to the short message handling process of standard the recipient user of appointment according to the recipient's Subscriber Number in this short message.
In addition, above-mentioned steps 106～108 can be carried out side by side with step 103～105.
The following describes the present invention and realize user's off-mode method of reporting.
Fig. 2 reports the method realization flow figure of an embodiment of user's off-mode for the present invention, may further comprise the steps:
Step 201, MS carry out power-off operation, initiate the deexcitation request to the MSC/VLR at this current place of MS.
After step 202, MSC/VLR receive the deexcitation request of this MS, send deexcitation message (MSINACT) to the HLR of this MS ownership.Wherein, the value of the parameter DeregistrationType in the deexcitation message is set to MS Power Down.
After step 203, HLR received deexcitation message, the on-off state that this MS is current was changed to shutdown, and returned deexcitation request response (msinact).
After above-mentioned user shut down the registration end, if HLR finds that the user is signatory and it is professional to have activated tracking, then HLR just can carry out real-time report to subscriber switch machine state according to the report manner of default.Similarly, report content can freely be set by operator, can be including, but not limited to following information: tracked Subscriber Number, current time, current location information and on-off state.Before reporting, user state information can be comprised information composition normative text information (TXTData) such as tracked Subscriber Number, current time, current location information and on-off state.
Similarly, report manner comprises the internal alarm mode, passes to third party or short message report manner by communication interface or EMAIL.If adopt the short message report manner, then need to continue to carry out following steps:
Step 204, HLR send to MC with state information and the short message receiving debit Subscriber Number that sets by SMDPP message.
After step 205, MC receive this short message, return short message to HLR and receive response message (smdpp), whether correctly received short message with feedback.
Step 206, MC send to this short message according to the short message handling process of standard the recipient user of appointment according to the recipient's Subscriber Number in this short message.
In addition, above-mentioned steps 204～206 can be carried out side by side with step 203.
By such scheme as can be seen, the present invention only need revise HLR business software logic just can realize tracking to user state information, therefore, scheme provided by the invention to other network entity of comprising terminal without any the change demand.And support of the present invention is circulated a notice of the state information of designated user in real time with short message way, and it is also very simple, quick to follow the tracks of handling process.
