Short message transmitting method and system, short message center and intercommunication gateway

Abstract

The invention discloses an industry short message transmitting method and system, a short message center and an intercommunication gateway. The industry short message transmitting method comprises the following steps: the short message center inquires RN attributes of portability operators to which called number users belongs, and transmits the RN attributes to the intercommunication gateway, the intercommunication gateway returns state reports comprising error codes corresponding to the RN attributes, the short message center transmits the state reports to industry clients, and the industry clients transmit industry short messages to the portability operators according to the error codes. ERR fields are extended to a SMGP (Short Message Gateway Protocol) and a SMPP (Short Message Peer To Peer) so as to supply the industry clients with relative information for judging the portability operators to which the users belongs, thereby the industry short messages can be correctly transmitted to the operators to which the user belongs, a normal industry short message business is supplied to the number portability users, the routing endless loop occurring between the industry clients and the short message gateway due to inconsistent database between the operators is also solved, and the risk of breakdown of the short message system is avoided.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for sending short messages for industries, a system for sending short messages for industries, a short message center and an intercommunication gateway. Background technique [0002] Industry short messages refer to non-commercial short message services provided by enterprises, public institutions, government agencies, etc. independently or entrusted by agency service providers for internal employees, customers and related personnel of customers, to meet their daily work management, information release, etc. needs. [0003] After the user's ported number is transferred to the network, the point-to-point SMS service can obtain the information of the user's ported operator through the user's original operator by querying the user database (NPHLR), so as to forward the SMS. [0004] There are differences in the sending methods of industry SMS and peer-to-peer ...

AI Technical Summary

Problems solved by technology

Industry customer (SP) users cannot obtain the information of the carrier brought in by the user by querying the user database of the operator, and cannot correctly send the industry SMS to the user side, so the industry SMS will still be sent to the SMS network of the operator who carried out the user. of users cannot normally receive industry text messages

[0005] The operator's inter-network SMS is only allowed to send point-to-point SMS. If the operator forwards the industry SMS to the user and brings it into the operator, it will also be intercepted by the operator, and the user cannot receive the industry SMS normally.

In addition, due to the differences in the industry customers developed by operators, the industry SMS service provided by the carrier cannot be continued after porting the network, and the industry SMS service provided by the porting operator must be used

[0006] Even if industry customers can correctly send short messages to users and bring them into the operator's network, the operator may fail to synchronize user database information and other reasons, resulting in asymmetric user database information between operators. For example, China Telecom marks that the user belongs to China Mobile and China Mobile Mark the attribution of telecommunications, resulting in an endless loop of routing between operators for SMS sent by industry customers

In this case, not only the user cannot receive the industry SMS, but also the SMS network system may be paralyzed
