Description
Technical field
The present invention relates to a kind of SMS value-added service, particularly relate to a kind of cut-in method of SMS value-added service.
Background technology
The branch operator that SMS value-added service is started to walk early, development is good is in order to strengthen the service management means to the value-added service in the Access Network, between SMSC and SP, added a kind of equipment that becomes value-added service platform one after another, when linking, such value-added service platform and SMSC all adopt the SMPP agreement of standard, SP then will adopt some proprietary agreements when inserting value-added service platform, and such agreement is more perfect than SMPP protocol function aspect service management.But the pattern of " SMSC+ value-added service platform+SP " still can't realize the networking of the whole network short message service, and key is the agreement that does not have networking between the value-added service platform.
And SMS value-added service is in a kind of state of doing things in his own way at present.The main cause that causes this state is that the SMSC of each branch company can't be by present general SMPP agreement (short MessagePeer to Peer, Short Message Peer to Peer) realizes networking, therefore SP is if will provide service for the user of a plurality of provinces, just must insert the SMSC of each province respectively, this situation has increased system and the human cost of SP greatly, has seriously hindered the development of SMS value-added service.
At present, the SMS value-added service access protocol of current international practice standard only has the SMPP agreement, and it is not that International Standards Organization is the standard access protocol that SMS value-added service is formulated at first, for no other reason than that it is simply suitable, application is more and more, thereby becomes international standard sanctified by usage.Also because so, the early stage version of SMPP is too simple, and not rigorous suspicion is arranged, to such an extent as to each SMSC manufacturer and operator when using, all need it is carried out some additional standards, so the version in the practical application can't be added up.
The SMPP agreement has been represented traditional access protocol, only considers that according to the system of its framework SMSC connects with the simple of ESME, does not consider the interconnected of SMSC or ESME, as shown in Figure 1.
ESME is the abbreviation of External Short Message Entity, and Short Message Entity is meant the entity that can initiate or transmit short message, and External Short Message Entity then refers to the Short Message Entity outside mobile network, generally provides the SP of SMS value-added service.SP can be by special line or Internet connection to SMSC, but all pass through the access that the SMPP agreement realizes business.
In SMPP3.3, in setting up the process that is connected with disconnection, SMSC is permanent server end, and ESME is permanent client, therefore has only ESME can initiate to set up and disconnect connection requests.Have only the connection of having set up, both sides could interactive service requests and service response.Yet SMSC also will initiate service request to ESME often, but it can not initiatively initiate connection request again, connects so it can only rely on ESME to initiate connection request.Obviously, ESME can't know when SMSC sends message and when do not have message to send, so ESME must set up a permanent connection that receives the message of SMSC initiation.Traffic carrying capacity reach relatively large before, such connected mode is to waste very much resource, so done improvement in SMPP3.4, allows SMSC to initiate an outbind prompting message ESME and connects.And about problems the such as whether load mode of packet in a connection and connection need to keep, how to keep, the not explanation of SMPP agreement.
And, in quasi-protocol, also adopted two kinds of connected modes: grow connection and be connected with short for other connected modes in the quasi-protocol.So-called length connects, and refers to can send a plurality of packets continuously in a connection, disconnects then connecting, and during connecting maintenance, if there is not packet to send, needs both sides to send out the link detecting bag.The short connection is the HTTP connected mode of standard, is meant when communication two party has data interaction, just sets up a connection, after data are sent completely, then disconnect this and connects, and the transmission of a business is only finished in promptly each connection.
The long connection is equivalent to permanent virtual connections, unless because the problem of network, just can not break in the foundation back, and the long advantage that connects is to connect both sides and can promptly sends next bar service request and needn't receive last replying before by asynchronous system communication.But on the wide area network of network service condition relatively poor (time delay is big, connection is easily broken), such advantage has just become inferior position.Because after connection is broken, though the TCP layer knows that at first this information will be through arriving after one section time delay (being generally the hundreds of millisecond on the Internet), secondly TCP layer can not inform initiatively that the application layer connection is disconnected.Like this, application program will send quite a lot of bags that are not identified when connection is broken, and the new foundation back application program that connects also must be retransmitted these bags.Not only do not improve communication efficiency in this case but also increased the burden of application program.
Short connection is the typical case with the connected mode (connected mode of http protocol is called again not have and connects) of http protocol, is promptly transmitting an information, after reception is replied, disconnects connection immediately, no longer sends out another service request.Purpose is to make application-level logic simple, and multithreading can be set up a plurality of short connections simultaneously, sends simultaneously.Especially under the situation of wide area network, can reduce the influence that network delay produces to greatest extent, make full use of bandwidth.But the short junction loss that connects is bigger than long connection, can obviously influence the efficient of message transmission when traffic carrying capacity is relatively concentrated.
Connected mode in the above two kinds of agreement all has common shortcoming, i.e. a very flexible.Can only initiate connection request by ESME in the SMPP agreement, SMSC side does not have foundation or disconnects the autonomy that connects; And under the short connected mode, though communicating pair can both initiatively connect, the restriction that connection can only be transmitted a packet is too inflexible again, causes efficiency of transmission low.Therefore above connected mode all can not be indiscriminately imitated fully, must improve.
And as shown in Figure 2, according to the mode of GSM division short message service flow process, all short message services all are divided into MO (by the short message of cellphone subscriber's submission) and MT (by the short message of cellphone subscriber's reception) two big flow processs.
Can see that by Fig. 1 and Fig. 2 traditional SMS value-added service access way is that network configuration or operation flow are all very simple.Business carry out early stage, this mode is more suitable, but traditional network configuration has following shortcoming:
(1) increased value service system directly move with basic network equipment on, each ISP will take a large amount of basic network facility and resource, for mobile operator, Internet resources are the most valuable, and directly allowing all kinds of service providers insert short message service center's equipment is a kind of significant wastage to wireless network resource.
(2) short message service center and SMPP agreement are considered seldom to the service management aspect, and operator lacks necessary means and methods at aspects such as the management of serving, service classification, service guarantees.Operator can't realize organically management and monitoring to the service that is inserted, and can't ensure service quality, and just serves as communication resource supplier's role.Therefore a lot of operators commence business for convenience, have added value-added service platform outside short message service center again.Be that value-added service platform and short message service center link, opposite side then can insert how tame SP.
(3) in the conventional network structure, short message service center is separate, can not realize the function of " a bit inserting the whole network service ".The SMPP agreement does not realize the interconnection protocol between each short message service center, and the local service that inserts can only be used for the local user, can't use for the strange land user.And value-added service platform above-mentioned can not be transmitted short message to other value-added service platforms.
Traditional SMS value-added service access protocol and network configuration thereof are unfavorable for that big operator provides unified SMS value-added service for the whole network user, are unfavorable for that also SP is at various places while promotion business.

Embodiment
SMS value-added service networked system of the present invention has another name called at communication system, it is by SMG (Short Message Gateway as Fig. 3, short messaging gateway), GNS (Gateway Name Server, the short messaging gateway routing server), SMSC (Short Message Service Center, short message service center) and the common networked system of forming of SP (Service Provider, service provider).Communications protocol between the SMG adopts SGIP agreement (Short Message Gateway Interface Protocol, the short message service networking protocol), in this system except that SMSC, other all inter-node communications all adopt SGIP, the described Short message Gateway Interface Protocol of this agreement, be used to finish transmission, reception and forwarding capability at short message between SMG and the SP, between SMG and the SMG, and the synchronizing function of routing table between SMG and the GNS.GNS is responsible for the management of system's route with synchronously.This system provides a powerful support platform for SMS value-added service.
The design of SMG is based on value-added service platform, and the SGIP agreement is used to realize communicating by letter between networking between the SMG and SMG and the SP, and GNS is used for realizing route unified management in the net.System global structure figure as shown in Figure 3, TSMG (Trans-Short Message Gateway wherein, the tandem short messaging gateway) closes the equipment of establishing for SMG and GNS, notion by the traditional communication net, it is GNS, make the SMG networking on plane become hierarchical network, the short message service networked system is become be easy to the carrier class Operation Network of managing and expanding with route tissue.
Network organization behind the introducing short messaging gateway as shown in Figure 4, as seen from Figure 4, SMG does not replace SMSC fully, but has added one deck short messaging gateway layer in traditional network organization again, between SP and SMSC.SP communicates by letter with proprietary protocol (SGIP agreement) with SMG, still adopts the SMPP protocol communication between SMG and the SMSC.Also interconnected between each SMG by the SGIP agreement.Each SMG can insert a plurality of SP, also can link with a plurality of SMSC simultaneously.In fact SMG is divided into two the function of the SMSC in the conventional network structure, duty-bound still the realizing of interface function with mobile network by SMSC, but SMSC directly inserts the function of SMS value-added service then have been replaced fully by SMG, and SMG expanded this function, increased functions such as service management, charging.
The target of short message service networked system of the present invention is to realize " a bit inserting; the whole network service ", but also considered the diversity of SP demand simultaneously, the present invention not only provides and has a bit inserted the whole network service manner for this reason, has also considered the mode that same SP multiple spot inserts when system design.In this manner, SP can be provided with special server in the bigger province of traffic carrying capacity, and the service of its whole network is still used in other provinces, even so, SP still can use the unified access code in the whole nation, thereby has guaranteed the consistency of SP to the whole network user propaganda.This is highly profitable to the SP larger, that business development is fast.When business norms formulation and engineering construction, the present invention can use national " SP/CP " is unified " 9 " prefix access codes.The trouble of all sms centers modification office datas of whole nation when SP inserts has been saved in this measure, the turn-on time of both having accelerated SP, has also improved reliability.
SGIP agreement of the present invention has been improved connected mode in the dedicated bearer mode.Set up mode in connection and broken through IP connection " the short connection " (HTTP connection commonly used, distribute packet and promptly disconnect connection) with the notion of " long be connected " (communicating pair is set up permanent connection), the pluses and minuses of comprehensive these two kinds of connected modes have proposed a kind of new connected mode---and " length connection ", after promptly connecting, as long as transfer of data is arranged, just keep connecting, just disconnect connection when having only within a certain period of time free of data transmission continuously, improved the efficient of transfer of data greatly.
SMS value-added service cut-in method of the present invention is when adopting special-purpose SGIP mode to carry access, in this short message service networked system based on the communicating pair of this SGIP agreement client and server end each other, promptly work as either party and can initiate connection request and service request, and the promoter of connection request and service request is consistent, for example, in this networked system between SMG and the SP, between SMG and the SMG, and between SMG and the GNS, equal client and server ends each other.And, when client will send service request, can initiatively connect to server end, send service request to server end then, and reception is replied; Server end receives service request from client, echo reply.Connect after the foundation, client can send a plurality of service requests continuously.Service request sends and receives all reply after, client should initiatively disconnect connection.But, service request and reply between the time interval maximum is arranged, i.e. maximum latency, as be 30 seconds (acquiescence can be provided with) if the time of wait acknowledge surpasses maximum latency, then requires client to retransmit this time service request; And the service request number of wait acknowledge also should have a upper limit, it is the maximum wait answer number, as 32 (can dispose) according to the quality of circuit and the disposal ability of server, when the maximum wait answer number of wait acknowledge exceeded default higher limit, then client stopped to send service request.In addition, connect the long-time free time if server end detects one, can initiatively disconnect this connection yet, promptly server end is not received the service request of client yet after a free time (giving tacit consent to 60 seconds, configurable) of being scheduled to, and then initiatively disconnects this connection.And if desired, client can be simultaneously set up a plurality of connections (SMG and single other SMG can not set up at most above 15 and be connected, and the maximum number of connections of the single SP that is attached thereto is determined on a case-by-case basis) to a server end.
In the present invention, when adopting special-purpose SGIP bearing mode, the port numbers of using between SMG and SMG, SP and the SMG is 8801, the port numbers that GNS monitors SMG is 8802, the port numbers that SMG monitors GNS is 8803, port numbers between main GNS and the standby GNS is 8804, and the test port numbers between the SMG is 8810.
Above-mentioned access mechanism of the present invention has following characteristics:
(1) connects the both sides' mode of client/server each other that connects that adopts;
(2) can set up a plurality of connections simultaneously;
(3) connect to set up after, client can wait acknowledge and send many service requests continuously, but the maximum number restriction is arranged;
(4) connect during line idle and will disconnect, wherein client disconnects connections when not having message to send, initiatively disconnection connection after server end also can be confiscated message in a period of time.
Below in conjunction with Fig. 5, Fig. 6 SMS value-added service cut-in method of the present invention further is elaborated.
As shown in Figure 5, show operation flow schematic diagram after the present invention has introduced short messaging gateway SMG.As shown in the figure, for the MO operation flow, when user terminal passes through the SMSC of the short message service center initiation service request of its ownership, short messaging gateway SMG by user ascription area transmits this user's service request to the short messaging gateway SMG that service inserts ground, insert ground SMG by this service and submit this user's service request to service provider SP to, at this moment, this user ascription area SMG and service insert between the ground SMG, this service inserts the mode that i.e. employing between ground SMG and the service provider SP the present invention is based on the SGIP agreement and insert.In this access procedure, this user ascription area SMG inserts ground SMG client and server end each other with service, this service inserts ground SMG and service provider SP client and server end each other, all can connect and inserts by the above-mentioned cut-in method of the present invention between them.In like manner, for the MT operation flow, this service of insert between the ground SMG in this service provider SP of issuing service information and service, transmitting business information inserts between ground SMG and the user ascription area SMG, also can adopt the above-mentioned cut-in method of the present invention to connect and inserts.
MO is not necessarily relevant with the MT operation flow among Fig. 5, also promptly not necessarily can trigger a MT flow process by a MO flow process.
As shown in Figure 6, show the short messaging gateway system business process that the present invention introduces GNS.Similar with the described flow process of Fig. 5, between user ascription area SMG and the gateway routing server GNS, gateway routing server GNS and service inserts between the ground SMG, service inserts and also can adopt the above-mentioned cut-in method of the present invention to carry out the miscellaneous service flow process between ground SMG and the service provider SP to handle, do not repeat them here.
Among Fig. 6 with 4 short messaging gateways of figure notation to GNS inquiry route and the step that obtains feedback be not in each operation flow all must through, only when can not find route in the routing table of short messaging gateway in self maintained, just have.
In addition, because the SGIP agreement is the interface protocol that is used between SP and short messaging gateway, GNS and short messaging gateway and the short messaging gateway, when the design connected mode, must consider the otherness of three kinds of interfaces.The developer of short messaging gateway and GNS should be the programmer who is proficient in communication software, thus the The design of communication of these two interfaces get can complexity a bit; And SP is the service provider, their speciality in the exploitation value-added service, the ability of exploitation communication software perhaps a little less than, especially for some by the information source unit of providing development and SP or little SP of coming are all the more so.Based on this consideration, can introduce the communication mode of the HTTP that SP quite is familiar with.The HTTP bearing mode only is applicable in the communicating by letter of SP and short messaging gateway SMG.The characteristics of this kind mode are not have to connect, and a request is only handled in promptly each connection.The intact client's of server process request, and after receiving the replying of client promptly disconnects and connecting.The mode of the authorization identifying of the URL of the authentication employing HTTP that connects, the message that does not need special connection to authenticate.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
