Description

Exception handling method and device for short message forwarding

technical field

The present invention relates to the field of communications, and in particular, to an exception processing method and device for short message forwarding.

Background technique

The short message forwarding service refers to a service in which a Short Message Service Center (Short Message Service Center, SMSC for short) forwards received messages to other SMSCs for processing according to a certain proportion or different message attributes.

In the related art, the short message center forwarding service mainly has the following application scenarios: different user attributes require different short message centers to perform normal processing; if the user opens an account in different short message centers, the relevant messages are only available in the home short message center. The center can handle it normally. Load sharing of message traffic between different short message centers is achieved through message forwarding; if the system is overloaded, messages are forwarded to other short message centers for load sharing. The role of the short message center is different, and the message needs to be forwarded between different short message centers; if some short message centers are only responsible for the first final call, if the final call fails, the message will be forwarded to the short message center specially responsible for retry for delivery. .

Different application scenarios of forwarding services determine that forwarding can occur in both the origination stage and the termination stage; Figure 1 is a flow chart of forwarding in the origination stage according to related technologies, as shown in Figure 1, the process includes: Follow the steps below:

Step S102, the terminal user submits the message to the short message center through the SS7 network;

Step S104, the short message center first judges whether the message needs to be forwarded according to different forwarding strategies;

Step S106, if forwarding, first obtain the address of the entity to be forwarded, and then forward the message out of the office;

Step S108, if not forwarding, continue to process other services in this short message center.

Abnormalities in the message forwarding process mainly include: the link with the destination SMSC is abnormal, for example, the forwarding message cannot be sent or the destination SMSC's forwarding response cannot be received; the destination SMSC service processing is abnormal, such as overload. In the related art, the above-mentioned forwarding exception processing is relatively simple: either reject the message or continue processing locally, which has a relatively negative impact on the use of the user.

At present, the short message center forwarding service is widely used in the international market, and different operators have completely different requirements for message forwarding conditions and forwarding disaster recovery.

Aiming at the low reliability and poor stability of the short message forwarding service system in the related art, no solution has been proposed so far.
