Description
Technical field
The present invention relates to the communications field, particularly the short message technology in the cell mobile communication systems.
Background technology
In present cell mobile communication systems, each mobile subscriber has homing position, i.e. a home network.In the external network outside the user roams into its home network, and when doing incoming call and breathe out, even carry out the incoming call of this roaming place breathes out in the roaming place, owing to will take the resource of roaming place network and its home network simultaneously, thereby can produce caller, called party's long-distance telephone expenses, make and increase the weight of the user's mobile phone cost burden.
In addition, when conversation occurs in different regions, in the time of particularly between the region of country boundary, though from the geographical position, only be separated by several kilometers,, owing to relate to operation rate, the price policy problem of different regions (country), cost of the phone call between these users is increased considerably,, thereby hindered information interchange and intercommunication dealing between the country border regions masses significantly because wherein contain great number even international telephone expenses that be difficult to bear.
At publication number is CN 1358040A, name is called in the Chinese patent application of " implementation method of cellular system virtual roaming and intercommunication and system ", a solution has been proposed, in across a network, cross-region, stride between the various wireless networks of system, realize user's free-roaming and interconnect, can save long-distance telephone expenses, and the user can be used for selecting for use arbitrarily suitable wireless network according to the usage charges of network quality and network, freely link up.Though this scheme has well solved the telephone expenses problem of calling out, and has been applied on existing network, in the processing of short message, does not propose feasible solution.When such " virtual roaming and intercommunicating system " set up in the region that has a common boundary in country, when the user of the user of country's roaming another country's roaming in system sends SMS message in the system, because transmit leg is walked international short messaging gateway to recipient's short message route, still can produce the international short message expense of great number.
Before the cellular system virtual roaming and intercommunicating system proposition that above-mentioned patent disclosed, if one roams in PLMN (Public Lands Mobile Network, abbreviation " PLMN ") customer call in roams in the user among another PLMN, PLMN of these two user attachings, handling process as shown in Figure 1.
Travelling carriage (Mobile Station is called for short " MS ") 2 roamings in Public Land Mobile Nerwork 1 (i.e. " PLMN1 " among the figure), the MS1 in the Public Land Mobile Nerwork 2 (i.e. " PLMN2 " among the figure) initiates the calling to MS2.
(the Mobile Switching Center of mobile switching centre among the figure, be called for short " MSC ")/VLR Visitor Location Register (Visitor Location Register, be called for short " VLR ") 1, MSC/VLR2 is the mobile ESC exchange servicing center/VLR Visitor Location Register that belongs to Public Land Mobile Nerwork PLMN2 and PLMN1 respectively, and attaching position register (Home Location Register, be called for short " HLR ") 1, HLR2 are the attaching position registers that belongs to Public Land Mobile Nerwork PLMN1, PLMN2 respectively.With reference to Fig. 1, at first in step 110, the MS1 under MSC/VLR1 is initiated to the calling of MS2; After this enter step 120, initiate to get the request of route by MSC/VLR1 to the attaching position register 2 (HLR2) of called MS 2; Then enter step 130, the HLR2 Query Database, discovery mobile station MS 2 is just being roamed in PLMN1, and the MSC/VLR2 in PLMN1 initiates the request of roaming number; Enter step 140 then, MSC/VLR2 returns the roaming number of MS2 to HLR2; Then enter step 150, HLR2 is to MSC/VLR1 loopback route response, and the roaming number of MS2 is returned to MSC/VLR1; Enter step 160 afterwards, the roaming number that MSC/VLR1 analyzes MS2 is external number or its network No. sign indicating number, sets up speech channel between MS1 and MS2, two internetwork continuing of PLMN of realizing speech channel by gateway exchange between international gateway or net; Enter step 170 at last, MS2 inserts, and conversation is hung up until the either party.
Above-mentioned steps shows, at existing global system for mobile communications (Global System for mobileCommunication, being called for short " GSM ") in the call flow of network, the roaming number that the HLR2 in the calling procedure directly gets access to MS2 in the MSC/VLR2 returns to MSC/VLR1's again; What HLR2 returned to MSC/VLR1 is the true roaming number of the true roaming position of sign MS2, pass through gateway exchange between international gateway or net for MSC/VLR1 with this roaming number, pathfinding is to the MS2 of MSC/VLR2, just can set up two internetwork speech channels of PLMN, long-distance telephone expenses in this calling procedure even international telephone expenses are inevitable.
In like manner, when MS1 belongs to different PLMN respectively with MS2, when promptly belonging to different HLR, speech channel also will be set up by gateway exchange between international gateway or net, cause the generation of long-distance telephone expenses even international telephone expenses.
" cellular system virtual roaming and the intercommunicating system " set up according to the technology contents of above-mentioned publication as shown in Figure 2.The HLR of a centralized management is set between all PLMN, and a GMSC (gateway mobile switching center) (Gateway MobileservicesSwitching Centre is called for short " GMSC ") that is used for the system equipment access is set in each PLMN.

According to principle of the present invention, solve because the problem that the international short messaging gateway great number note that short message causes by international short message gateway exchange is taken.Generally speaking, the present invention is routed to corresponding GMSC in the system by the short message that international short messaging gateway is sent down, and sends by internal system, thereby avoids international short message expense.
Need to prove, in the invention scheme of patent CN1358040A " cellular system virtual roaming and intercommunicating system ", between all need the PLMN of virtual roaming and intercommunication, be provided with the HLR of a centralized management, and in each needs the PLMN of virtual roaming and intercommunication, be provided with one and be used for the GMSC that system equipment inserts; In addition, total ownership location register HLR is connected with each GMSC, total ownership location register HLR needs the PLMN of virtual roaming and intercommunication to be connected by signaling transfer point and each, and each GMSC is connected with the PLMN at place and is connected with the long-distance transport net by gateway device.
The present invention program on this basis, make the inner short message that issues by international short message gateway exchange originally intercept intrasystem GMSC and issue, produce international gateways and remember expense owing to going out international short messaging gateway thereby avoid roving short message that the MSC/VLR mobile subscriber down of two countries sends out mutually through HLR.Because the function of the stack of the GMSC in the invention scheme of patent CN1358040A " cellular system virtual roaming and intercommunicating system " short messaging gateway short message issuing, therefore the present invention program will originally intercept the GMSC of system through the short message of international short messaging gateway route, to send SMS message to the GMSC that receives this short message by this GMSC afterwards, thereby be implemented in short-message sending under the internal system, avoided international short messaging gateway.Wherein, concrete interception mode has two kinds.
Fig. 5 shows interception short message according to an embodiment of the invention also passes through following short-message sending in the system to GMSC scheme.
Wherein, MS1 is the travelling carriage of roaming under the MSC/VLR1 in PLMN2, and MS2 then is the travelling carriage of roaming under the MSC/VLR2 in PLMN1.Those skilled in the art should be understood that MS1 and MS2 can be mobile terminal devices such as mobile phone, individual palmtop PC, notebook.
And MSC/VLR1, MSC/VLR2 are the mobile ESC exchange servicing center/VLR Visitor Location Registers that belongs to PLMN2 and PLMN1 respectively, and HLR1 and HLR2 then are the attaching position registers that belongs to Public Land Mobile Nerwork PLMN1, PLMN2 respectively.The technical staff in field of the present invention is appreciated that HLR1 and HLR2 can be one physically.MSC/VLR wherein is switching center and database, and they provide circuit-switched service in the current location of MS for it.HLR is a database that is positioned at the subscriber's local system, and it is storing active and standby part that user performance characteristic is described, and comprises all permanent datas of user.
It should be noted that the GMSC among Fig. 5 is responsible for the short messaging gateway that short message sends specially, this GMSC finds the position of message recipient present located MSC according to corresponding roaming agreement, and short message finally is forwarded to this MSC.GMSC1 and GMSC2 then are gateway MSCs, and it is responsible for the switching equipment that is connected with the external circuit switching network.
Below with reference to Fig. 5, specifically describe the process that communicates to connect that MS1 sends SMS message to MS2 according to the present invention program.
As shown in Figure 5, at first in step 510, the short message that is sent to MS2 by MS 1 at first is sent to MSC/VLR1.Subsequently in step 520, MSC/VLR1 sends to short message service center's (Service Centre is called for short " SC ") of MS1 correspondence with short message, and this short message is preserved by SC.Those skilled in the art are to be understood that the major function of SC stores and transmit short message exactly, and SC realizes on the high-speed service applicator platform that normally for example the SC of Nokia is exactly 9000 servers that utilize Hewlett-Packard.
After this, short-message sending under the SC request GMSC3 in step 530, need to prove, GMSC3 herein is responsible for the short messaging gateway that short message sends specially, this GMSC3 is according to corresponding roaming agreement, find the position of message recipient present located MSC, and short message finally is forwarded to this MSC.
Next, after receiving this request, in step 540, GMSC3 initiates short message according to the number of the short message that receives to HLR2 and gets route requests.Then, in step 550, HLR2 finishes Query Database and finds that MS2 roams at PLMN1, so to HLR1 request customer position information, and enter step 560.
In step 560, after HLR1 receives this request customer position information, the GMSC1 number of recipient MS2 place PLMN network is returned to HLR2 as the MSC/VLR2 number at MS2 roaming place.
After HLR2 receives this information,, and enter step 580 so in step 570 subsequently, HLR2 returns short message with the GMSC1 number to GMSC3 and gets route response.
In step 580, GMSC sends to GMSC2 according to the route data to GMSC1 of configuration earlier with short message.So just make short message to be issued to MS2, but by short-message sending under the GMSC2 by international short message gateway exchange.
In step 590, GMSC2 is sent to GMSC1 with this short message then, so just makes short message send among the PLMN1 through GMSC2, and has save the note expense of international short messaging gateway.
After this, in step 600, GMSC1 obtains the IMSI that receives short message side from the request of following short-message sending, initiates short message according to this number to HLR1 and gets route, and enter step 610.
In step 610, HLR1 gets route response with the actual position information of MS2 as short message and returns to GMSC1.And in following step 620, GMSC1 sends to the MSC/VLR2 that the recipient roams the place with short message.
Subsequently, in step 630, MSC/VLR2 gives user MS2 with short message issuing, finishes the communication process that this short message is sent to the purpose travelling carriage.
Send in the handling process at above short message, the MSC number that the gateway MSC GMSC1 number that HLR2 will receive MS2 place, short message side PLMN1 is roamed the place as the user returns to the short messaging gateway GMSC3 of transmit leg MS1, and short messaging gateway GMSC3 is according to its route data, to send this short message to recipient's gateway MSC GMSC1 by the gateway MSC GMSC2 among the PLMN2, thereby be implemented in short-message sending under the internal system, avoided international short messaging gateway.
Fig. 6 show according to another embodiment of the invention interception short message to GMSC the scheme by short-message sending under the internal system again.
Wherein, the same with shown in Fig. 5, MS1 and MS2 are respectively the travelling carriages of roaming under MSC/VLR1 and MSC/VLR2, MSC/VLR1 and MSC/VLR2 then are respectively the mobile switching center in PLMN2 and PLMN1.And the character of MSC/VLR1, MSC/VLR2 and HLR1, HLR2 and GMSC3, GMSC1 and GMSC2 and belonging positions all with Fig. 5 in correspondent entity in full accord, at this simple and clear just repeated description no longer for article.
Below with reference to Fig. 6, specifically describe the process that communicates to connect that MS1 sends SMS message to MS2 again according to the present invention program.
As shown in Figure 6, at first in step 710, MS1 at first is sent to MSC/VLR1 with short message.After this, in step 720, MSC/VLR1 sends to the SC of MS1 correspondence with short message, and SC preserves this short message.
After this, in step 730, short-message sending under the SC request short message gateway GMSC3.In following step 740, GMSC3 initiates short message according to the number of the short message that receives to HLR2 and gets route requests after receiving this request.
Then, in step 750, the HLR2 Query Database finds that MS2 roams at PLMN1, and short message is from PLMN2, so HLR2 returns to short messaging gateway GMSC3 with the gateway MSC GMSC2 number among the PLMN2 as the MSC/VLR2 number that MS2 roams the place.Subsequently, enter step 760.
In step 760, GMSC3 is short-message sending under GMSC2.GMSC2 receives this short message, and in step 770 subsequently, GMSC2 obtains the IMSI number that receives short message side from the request of following short-message sending, initiates short message according to this number to HLR2 and gets route.After this, enter step 780.
In step 780, HLR2 gets route response with the actual position information of MS2 as short message and returns to GMSC2, then just make short message to issue by international short message gateway exchange, but can be by the MS2 of short-message sending under the GMSC2 in the PLMN1.
Then, in step 790, GMSC2 is sent to GMSC1 with this short message, so just make that the short message of interception sends among the PLMN1 through GMSC2, and do not need short-message sending under the international short message gateway exchange of approach, but issue by internal system, so just avoided causing the note expense of international short messaging gateway, reduced the expense that internal system sends international short message.
After this, in step 800, GMSC1 sends to MSC/VLR2 among the recipient PLMN1 with this short message.In step 810 subsequently, MSC/VLR2 gives MS2 with the short message issuing that receives again.So far, whole short message process of transmitting finishes.
Short message at the 2nd above-mentioned embodiment sends in the handling process, the gateway MSC GMSC2 number MSC number of roaming the place as the user that will MS1 place, the side of sending SMS message network PLMN2 by HLR2 returns to the short messaging gateway GMSC3 of transmit leg, make short message be sent to the critical point Mobility Center GMSC3 of PLMN2, send SMS message to recipient's gateway MSC GMSC1 by this gateway MSC GMSC2 more afterwards, thereby be implemented in short-message sending under the internal system, avoid international short messaging gateway, saved the expense that international short message sends.
By above as seen, " cellular system virtual roaming and the intercommunicating system " that the present invention is based on special CN1358040A solves the scheme that short message charges, the cellular system virtual roaming and the existing network entity of intercommunicating system that disclose in above-mentioned patent have been made full use of, the short message that internal system is originally issued by international short message gateway exchange is issued by the gateway MSC GMSC of system, avoid out the charging of international short messaging gateway, thereby reduce the expense that internal system sends international short message.
