Device and method for processing short message service

This application is a continuation of International Application No. PCT/CN2010/077716, filed on Oct. 13, 2010, which claims priority to Chinese Patent Application No. 200910206835.1, filed with the Chinese Patent Office on Oct. 15, 2009, and entitled “DEVICE AND METHOD FOR PROCESSING SHORT MESSAGE SERVICE”, both of which are incorporated herein by reference in its entirety.

The present invention relates to the field of mobile communications, and in particular, to a device and a method for processing a short message service.

Currently, the short message service has become one of the most commonly used services of cell phone subscribers. In addition to a large number of point-to-point short message services, short message services from information platforms on the Internet to cell phone subscribers are developing rapidly. A short message gateway may provide a safe and fast channel for data exchange between a service provider (Service Provider, SP) and a short message center, and implement functions such as SP convergence, routing management, accounting and authentication, and storage and forwarding, so the establishment thereof is quite necessary. Along with the rapid development of services, requirements on the short message gateway become higher and higher, which are mainly embodied as: (1) processing short messages in high capacity/high rate; (2) having high reliability; (3) having low total costs of ownership (TCO); and (4) being capable of expanding dynamically.

As shown in FIG. 1 , a conventional static cluster short message gateway is shown, which may be understood as the superposition of single sets of short message gateway, for fixedly allocating different service flows to a certain set of device in the cluster through a load balancer. The static cluster gateway is a whole for the short message center and an Enterprise Customer/Service Integrator (Enterprise Customer/Service Integrator, EC/SI), instead of a gateway 1 , a gateway 2 and the like shown in FIG. 1 .

In the foregoing technique, a waiting status report entity (that is, an original message for being matched with a status report, where if the matching is successful, it indicates that a short message is sent successfully) of the EC/SI can only be saved in a memory or database of the device, for being matched after a status report entity (that is, a report message for indicating whether a terminal has received the message successfully) is returned from a lower-level network element, and therefore, the service flow of a single EC/SI can only be allocated on a certain gateway device. If some gateway is down, a related service using the gateway is interrupted, and when the corresponding status report is returned from the lower-level network element, the status matching cannot be performed, thereby having low reliability.

An embodiment of the present invention provides a device for processing a short message service, which is capable of high-reliably processing a short message service.

A device for processing a short message service includes a plurality of access units and a plurality of service processing units, where each of the access units is connected to the plurality of service processing units;

the access unit is configured to receive a short message service and send it to one of the service processing units, and send out the processed short message service from the service processing unit; and

the service processing unit is configured to process the short message service, and send out the processed short message service through one of the access units.

An embodiment of the present invention further provides a method for processing a short message service, which is capable of high-reliably processing a short message service.

A method for processing a short message service includes:

receiving, by a first access unit, a short message service;

sending, by the first access unit, the short message service to a first service processing unit; and

processing, by the first service processing unit, the short message service, and sending out the processed short message service through any access unit;

where, the first access unit is obtained by selecting from more than two preset access units, and the first service processing unit is obtained by selecting from more than two preset service processing units.

By adopting the device and method for processing the short message service, one of more than two preset access units is capable of receiving the short message service and sending it to one of more than two preset service processing units, so, when a certain access unit or service processing unit is down, other access units or service processing units may still bear the work of the down access unit or service processing unit, thereby high-reliably processing the short message service.

An embodiment of the present invention provides a device and a method for processing a short message service, which are capable of high-reliably processing a short message service.

The present invention is described in detail in the following with reference to the accompanying drawings. The embodiments to be described are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by persons skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

As shown in FIG. 2 , a device 200 for processing a short message service provided in an embodiment of the present invention includes a plurality of access units 201 and a plurality of service processing units 202 , where each of the access units 201 is respectively connected with the plurality of service processing units 202 . The access unit 201 is configured to receive a short message service and send it to one of the service processing units 202 , and send out the processed short message service from the service processing unit 202 . The service processing unit 202 is configured to process the short message service, and send out the processed short message service through one of the access units 201 .

It should be understood that, the short message service herein may be a text short message service in the common sense, and may also be a multimedia message service or a short message service of another type. Moreover, according to actual application environments, the device 200 for processing the short message service may communicate with one or more external network elements. For example, when the device 200 for processing the short message service is used as an enhanced device of the conventional static cluster gateway, the device 200 for processing the short message service receives a short message service from an EC, processes the short message service, and sends the processed short message service to a short message center (in the case that the short message is sent to the local place) or a forwarding gateway (in the case that the short message is sent to another place).

In addition, in the device 200 for processing the short message service, all the access units 201 may provide the same processing capability to the external, and distribute, according to a load balance mechanism, tasks to one of the service processing units 202 currently working normally. If a certain access unit 201 goes down, any of other access units 201 is capable of bearing the load of the certain access unit 201 automatically. In addition, each of the service processing units 202 may have an equal processing capability.

When adopting a device 200 for processing the short message service, one of the plurality of access units 201 is capable of receiving the short message service and sending it to one of the plurality of service processing units 202 , therefore, when a certain access unit 201 or service processing unit 202 goes down, other access units 201 or service processing units 202 may still take over the work of the down access unit 201 or service processing unit 202 , thereby high-reliably processing the short message service, so that the device 200 for processing the short message service is highly extensible and may be on-line upgraded in real time.

Further, as shown in FIG. 3 , a device 200 for processing the short message service may further include a plurality of storage units 301 , and each storage unit 301 is configured to store a waiting status report entity. In such a case, a service processing unit 202 is further configured to, after sending out the processed short message service through one of the access units 201 , generate a waiting status report entity, store the waiting status report entity in one of the storage units 301 ; receive a waiting status report entity that is sent by one of the access units 201 and obtained from the storage unit 301 and a status report that is received by the access unit 201 from the external of the device 200 for processing the short message service, match the two, and send out a matching result through one of the access units 201 . By executing the foregoing operations, it can be determined whether the short message service is successfully sent to a cell phone or an application terminal.

In addition, the service processing unit 202 may be further configured to, after obtaining the matching result, clear the waiting status report entity that is in the storage unit 301 which has been used for matching the status report, thereby preventing the storage unit 301 from having no idle space to store a subsequent waiting status report entity.

A work flow of the device 200 for processing the short message service is illustrated in the following by taking the device 200 for processing the short message service shown in FIG. 3 as an example. As shown in FIG. 4 , the flow includes:

S 401 : an EC/SI delivers a short message service to one of access units 201 A currently working normally;

S 402 : according to a load balance mechanism, the access unit 201 A sends the short message service to one of service processing units 202 A currently working normally;

S 403 : the service processing unit 202 A sends a response to the EC/SI through the access unit 201 A;

S 404 : the service processing unit 202 A processes the short message service;

S 405 : if the access unit 201 A goes down, the service processing unit 202 A, according to a message destination address, delivers the processed short message to a short message center (in the case of sending the short message to the local place) or a forwarding gateway (in the case of sending the short message to another place) through one of access units 202 B currently working normally;

S 406 : a response returned by the short message center or the forwarding gateway is sent to the EC/SI and a service processing unit 202 B currently working normally through the access unit 202 B currently working normally;

S 407 : the service processing unit 202 B currently working normally generates a waiting status report entity;

S 408 : the service processing unit 202 B currently working normally stores the waiting status report entity in one of storage units 301 A;

S 409 : the access unit 201 B currently working normally receives a status report from the short message center or the forwarding gateway;

S 410 : the access unit 201 B currently working normally obtains the waiting status report entity from the storage unit 301 A;

S 411 : the access unit 201 B currently working normally, according to an internal mechanism, sends the waiting status report entity and the status report to one of the service processing units currently working normally, which is the service processing unit 202 B;

S 412 : the service processing unit 202 B sends a status report response message to the short message center or the forwarding gateway through the access unit 201 B;

S 413 : the service processing unit 202 B performs a matching process on the status report and the waiting status report entity;

S 414 : the service processing unit 202 B clears the waiting status report entity in the storage unit 301 A;

S 415 : the service processing unit 202 B sends a matching result to the EC/SI through one of the access units currently working normally, which is the access unit 201 A; and

S 416 : the EC/SI sends a matching result response to the service processing unit 202 B through one of the access units currently working normally, which is the access unit 201 A.

By adopting the foregoing work flow, the processing of the short message service no longer depends on the operation situation of a certain service processing unit or access unit, so the reliability is improved, and when the device 200 for processing the short message service is used as a cluster gateway, the expandability of the cluster gateway is increased.

Further, as shown in FIG. 5 , the service processing unit 202 includes a plurality of service processing modules 501 . Each of the service processing modules 501 is respectively connected to the plurality of access units 201 , and is configured to process the short message service (in the case of the device 200 for processing the short message service does not have storage units); or each of the service processing modules 501 is respectively connected to the plurality of access units 201 and respectively connected to the plurality of storage units 301 , and is configured to process the short message service and perform the matching process of the waiting status report entity and the status report (in the case of the device 200 for processing the short message service includes the storage units). In this way, each of the service processing units 202 may be deployed at different places for different use. For example, one service processing unit 202 is used for a key account of business industry, and when a short message service comes from the key account of business industry, one of the service processing modules 501 currently working normally of the service processing unit 202 processes the short message service. For another example, another service processing unit 202 is used for a key account of education industry, and when a short message service comes from the key account of education industry, one of the service processing modules 501 currently working normally of the service processing unit 202 processes the short message service. Certainly, for an external EC/SI, there is no need to concern which service processing unit 202 is specifically accessed.

Further, as shown in FIG. 6 , the storage unit 301 includes: a location register 601 , configured to store location information of the waiting status report entity (such as, stored in which storage sub-unit 602 ); and a storage sub-unit 602 , configured to store the waiting status report entity. At this time, the access unit 201 is specifically configured to, according to the uniqueness of a short message identity, obtain the location information of the waiting status report entity from the location register 601 , and obtain the waiting status report entity from the corresponding storage sub-unit 602 according to the location information. Certainly, the access unit 201 may also be specifically configured to, according to the uniqueness of a short message identity, obtain the location information of the waiting status report entity from the location register 601 , and send the location information to one of service processing units 202 currently working normally. The service processing unit 202 then obtains the waiting status report entity from the corresponding storage sub-unit 602 according to the location information.

As shown in FIG. 7 , a method for processing a short message service provided in an embodiment of the present invention includes:

S 71 : a first access unit receives a short message service;

S 72 : the first access unit sends the short message service to a first service processing unit; and

S 73 : the first service processing unit processes the short message service, and sends out the processed short message service through any access unit;

where, the first access unit is obtained by selecting from at least two preset access units, and the first service processing unit is obtained by selecting from at least two preset service processing units.

It should be understood that, the short message service herein may be a text short message service in the common sense, and may also be a multimedia message service or a short message service of another type. Moreover, according to actual application environments, the access unit herein may implement the communication with one or more external network elements. For example, one of at least two preset access units receives a short message service from the EC and sends it to one of more than two preset service processing units, the service processing unit processes the short message service, and the service processing unit sends the processed short message service to a short message center (in the case that the short message is sent to the local place) or a forwarding gateway (in the case that the short message is sent to another place) through one of the more than two preset access units.

By adopting the method for processing the short message service, one of more than two preset access units is capable of receiving the short message service and sending it to one of more than two preset service processing units, so, when a certain access unit or service processing unit goes down, other access units or service processing units may still bear the work of the down access unit or service processing unit, thereby high-reliably processing the short message service.

Further, in step S 71 , the obtaining the first access unit by selecting from at least two preset access units is specifically: obtaining the first access unit by selecting from more than two preset access units according to a load balance mechanism.

Further, as shown in FIG. 8 , after step S 73 , the method further includes:

S 81 : the first service processing unit generates a waiting status report entity and stores the waiting status report entity in a first storage unit, where the first storage unit is obtained by selecting from more than two preset storage units; and

S 82 : a second access unit receives a status report, queries in the storage unit for a waiting status report entity corresponding to the short message, and sends the waiting status report entity and the status report to a second service processing unit;

where, the querying in the storage unit for the waiting status report entity corresponding to the short message is specifically: according to the uniqueness of a short message identity, obtaining location information of the waiting status report entity, and obtaining from the storage message the waiting status report entity corresponding to the short message based on the location information.

Certainly, the step S 82 may also be implemented as: the second access unit receives the status report and obtains the location information of the waiting status report entity (for example, which one of the more than two preset storage units is stored with the waiting status report entity) according to the uniqueness of the short message identity, the second access unit sends the location information and the status report to the second service processing unit, and the second service processing unit obtains the waiting status report entity from the corresponding storage unit according to the location information.

S 83 : the second service processing unit performs a matching process on the waiting status report entity and the status report, and sends out a matching result through any access unit.

It can be determined whether the short message service is successfully sent to the cell phone or application terminal by performing the steps S 81 to S 83 .

Further, in step S 83 , after the performing, by the second service processing unit, the matching process on the waiting status report entity and the status report, the method further includes: clearing, by the second service processing unit, the waiting status report entity in the storage unit, thereby preventing the storage unit from having no idle space to store a subsequent waiting status report entity.

It should be understood that, the first access unit and the second access unit may be the same or different; the first service processing unit and the second service processing unit may be the same or different.

It should also be understood that, the device and method for processing a short message service described herein may be applied in a network element such as a gateway and a short message center.

Those skilled in the art should understand that all or apart of the flow of the method according to the embodiments of the present invention may be implemented by a computer program instructing relevant hardware. The program may be stored in a computer readable storage medium. When the program is run, the flows of the methods according to the embodiments of the present invention are performed. The storage medium may be a magnetic disk, an optical disk, a Read-Only Memory (Read-Only Memory, ROM), or a Random Access Memory (Random Access Memory, RAM).

The foregoing descriptions are merely several embodiments of the present invention, but not intended to limit the present invention. Various variations and modifications made by persons skilled in the art without departing from the spirit of the present invention fall within the scope of the present invention. Therefore, the protection scope of the present invention is subject to the appended claims.
