Detailed Description
The embodiments and preferred embodiments of the short message terminal router system and method according to the present invention will be described in detail below with reference to the accompanying drawings.
The invention relates to a short message terminal router system and a method based on a target home network, which mainly have the core points that for a routing request sent by an external network short message center, the address of a short message center terminal router under the target home network is adopted to replace the address of a service short message center in a routing response; as for the GSM/UMTS, PLMN, HLR, SMSC, IMSI, ASP, MT and MS technologies, etc., are well known to those skilled in the art and will not be described herein.
A short message terminating router system based on a destination home network, as shown in fig. 1, comprising a signaling processing module 110 and a service processing module communicatively connected to each other, wherein:
the signaling processing module 110 is located at a Home Location Register (HLR) side of a destination Home network, and is configured to process an interworking short message terminating signaling forwarded from a signaling network side, and forward the terminating short message to the service processing module for service processing;
and the service processing module is positioned at the short message value-added service platform side of the target home network and is used for checking the target subscriber number and the value-added service thereof.
It should be noted that the HLR in this document is a modified HLR system, and specifically includes a distinguishing submodule located on the destination subscriber home network side, for distinguishing the routing request sent from the foreign short message center. For a query routing request sent by a Short Message service center (Short Message service center, SMSC for Short hereinafter), Short messages need to be forwarded to an SMS-ROUTER at an sccp (signaling Connection Control part) signaling Connection Control protocol layer; as shown in fig. 2, if the user state is normal, the address of the serving MSC (mobile switching Center, hereinafter abbreviated as MSC) of the user is returned, and if the user state is abnormal, an error routing response is returned.
Specifically, as shown in fig. 1, the signaling processing module 110 further includes a short message center terminating ROUTER SMS-ROUTER and a short message center-interworking/mobile network gateway office SMS-IW/GMSC, which are both located at the short message center side and are communicatively connected to each other, wherein:
1) the short message center terminal call ROUTER SMS-Router is used for re-initiating a routing request to the home location register HLR after receiving a routing application from an external network short message center;
2) the short message center-intercommunication/mobile network gateway office SMS-IW/GMSC is used for caching the routing request received by the home location register HLR, and forwarding the routing request to the service processing module after being associated with the terminal call short message from the foreign network short message center.
The service processing module is used for checking whether a target user has a number portability function, whether a target user subscribes a value-added service and the like; the system specifically comprises a monitoring submodule, a final calling submodule and a statistic submodule which are connected in sequence; the monitoring submodule is used for monitoring the spam short messages; and finally, the terminal calling sub-module carries out terminal calling on the short message, and the statistical sub-module carries out relevant statistics on the short message and generates a ticket. The service processing module is a core module of the short message center and is mainly responsible for storing and forwarding the short message; as shown in fig. 3, the SMS processing module needs to add a processing loop flow of the terminating short Message MT Message received from the SMS-ROUTER: firstly, checking whether the target user belongs to the short message center and whether the short message value-added service is signed, simultaneously copying the short message to a spam short message monitoring system for spam short message monitoring, then sending the short message, and finally performing performance statistics on the short message to generate a corresponding ticket and the like. Under the condition that the user does not sign short message forwarding service, the SMS-Router already acquires the routing information of the short message, so that the routing information can be brought to the SMS-IW/GMSC module through the internal interface when the short message is called, and the SMS-IW/GMSC directly calls the short message to the service MSC without initiating a routing request again.
More specifically, the SMS-route further includes an address replacement sub-module for replacing the address of the serving SMS in the routing response with the address of the SMS-route according to the routing response received or returned by the HLR, and initiating the routing response to the foreign SMS. The SMS-Router is developed on an SMS-IW/GMSC module of a short message center, initiates a routing request to the HLR again after receiving a routing request of an extranet short message center forwarded by the HLR, and replaces the service MSC address of a target user with the address of the ROUTER after receiving a routing response returned by the HLR; and then initiates a routing response to the short message center of the external network. After the short message center of the external network sends the short message of the terminal call to the SMS-route, the SMS-route is associated with the MSISDN of the target user, the priority of the short message, the IMSI of the target user, the service MSC address, the short message of the terminal call and the like, and then the SMS-SC short message service processing module is sent together.
For the processing of the short message value-added service, some short message systems use the short message value-added service as an additional function of a short message center to be directly implemented in the short message center, some short message systems use the short message value-added service alone as a platform to be matched with the short message center to implement the short message value-added service, and the latter has many advantages and will become a trend of the development of the short message system value-added service, therefore, fig. 4 illustrates an example of implementing the short message forwarding service by matching the short message center and the short message value-added service platform, and the signaling processing module 410 in fig. 4 is equivalent to the signaling processing module 110 in fig. 1.
The short message system with the function of the short message terminal call router of the invention is utilized to route the intercommunicating short message terminal call signaling to the short message center to which the target user belongs, and the invention comprises the following steps:
step one, distinguish the route request sent by the short message center of the outer network, process the intercommunication short message final call signaling forwarded from the signaling network side. During specific operation, if a route query request sent by an external network SMSC is received, a route application from an external network short message center is received, the route request is sent to a home location register again, the short message is forwarded to an SMS-Router, and a route response is returned by the home location register; if receiving the request of inquiring route sent by local network SMSC, keeping the original processing flow.
And step two, the signaling processing module of the target home network transfers the terminal call short message to a service processing module for service processing. Replacing the address of the service short message center in the routing response by the address of the short message center terminating router according to the returned routing response; initiating a routing response to an external network short message center; and caching the routing request received by the home location register, associating the routing request with a terminating short message from an external network short message center, and then forwarding the terminating short message to the service processing module.
During the specific operation, after receiving the routing request of the short message terminal ROUTER SMS-Router from the external network short message center forwarded by the HLR, the SMS-Router re-initiates the routing request short message to the HLR, and comprises an address replacement submodule for replacing the address of the SMS-Router with the service MSC address in the routing response of the HLR according to the routing response received or returned by the HLR, and then initiates the routing response to the external network short message center, so that the external network short message center sends the terminal calling short message to the SMS-Router. The SMS-Router needs the short message center-interworking/mobile network gateway office to cache the MSISDN of the destination subscriber number in the routing request received from the HLR, the priority flag of the short message, and the IMSI number and the service MSC address in the routing response received from the HLR, and then the service MSC address is associated with the short message called by the short message center of the external network and then forwarded to the service processing module SMS-SC.
Step three, the service processing module at the short message value-added service platform side checks the target user number and the value-added service thereof. The method specifically comprises the following steps: checking the number of the target user, checking whether the target user is a home user of the local network short message center and belongs to a mobile number carrying user; checking the value-added service of the target user, checking whether the target user signs the value-added service, such as functions of call forwarding, short message receipt and the like, if the target user signs the value-added service, realizing the value-added service of the user either in a short message center or by matching with a short message value-added service platform ASP; if the target user does not sign the value-added service, the short message is directly called; further comprising: the terminal call short message is copied to a spam short message monitoring system for spam short message monitoring; the terminal call short message is called; and performing performance statistics on the terminal call short message and generating a ticket.
When the short message center SMSC and the short message value-added service platform ASP are matched to realize the processing of the value-added service, as shown in figure 4, after a short message center service processing module SMS-SC receives a short message final call signaling MT forwarded by an SMS-Router, the user account opening information of a target user is checked, the target user is found to sign a short message forwarding service, and then the short message is sent to the short message center value-added service platform ASP through a Relay _ SM; ASP stores the number of user signing short message forwarding, ASP replaces the short message destination number with the forwarding number and then submits the short message to the short message center again by Submit _ SM, the short message center sends the short message and reports the short message sending state to the short message value-added service platform ASP by Deliver _ Report _ SM, ASP receives the short message and reports the original Relay _ SM short message state to the short message center again by Deliver _ Report _ SM, thus completing the short message forwarding service process.
The technology of the short message terminating router in the above preferred embodiment may adopt various possible schemes according to practical applications, which are well known to those skilled in the art and will not be described herein again.
In the embodiment of the invention, the address of the short message center terminal call router under the target home network is adopted to replace the address of the service short message center in the routing response, so that the conventional short message system has the function of the short message terminal call router, and the problems that short messages intercommunicated in a signaling mode under a GSM/UMTS system cannot realize value-added service of the short message target for a target user, cannot monitor junk short messages and the like are solved, thereby perfecting the function of the short message system and increasing income for operators.
It should be understood that those skilled in the art may make modifications or changes according to the above description, for example, the distinguishing submodule for distinguishing the non-home network routing request is independent of the HLR, etc., and all such modifications and changes should fall within the protection scope of the appended claims.
