Background technology
In the existing communication technical field, short message service provides a kind of conveniently communication mode for users.Because short message service is convenient and swift when realizing people's exchanges and communication, expense is also lower, so short message service is in recent years developed rapidly, and becomes a kind of very important communication service.
In realizing the process of short message service, the reception of short message is to link together with concrete telephone number, and the short message that promptly sends to number B can only be that the communication terminal of B receives by number.
As shown in Figure 1, Fig. 1 realizes the networking structure schematic diagram that short message sends and receives in the prior art.Number is the transmission terminal of the communication terminal of A as short message, abbreviate terminal A as, the residing mobile switching centre of terminal A (MSC) is MSC-A, and the short message service center (SMC) of terminal A ownership is SMC-A, and the attaching position register (HLR) of terminal A ownership is HLR-A; Number is the receiving terminal of the communication terminal of B as short message, abbreviates terminal B as, and the residing MSC of terminal B is MSC-B, and the SMC of terminal B ownership is SMC-B, and the HLR of terminal B ownership is HLR-B.
As shown in Figure 2, Fig. 2 realizes the method flow diagram that short message sends and receives in the prior art, and this method may further comprise the steps:
Step 201: terminal A sends to SMC-A by MSC-A with short message;
Step 202:SMC-A sends to SMC-B according to the number of terminal B with short message;
Step 203:SMC-B and HLR-B carry out alternately, obtain terminal B present located MSC number, can not access state if terminal B is in shutdown or breaks away from service area etc., SMC-B can't obtain terminal B present located MSC number, this moment, SMC-B was with this short message of buffer memory, until having obtained terminal B present located MSC number, according to the terminal B present located obtained MSC number, short message is sent to MSC-B then;
Step 204:MSC-B sends to terminal B with short message, the short message that terminal B receiving terminal A sends over.
In above-mentioned steps 203, if short message time of buffer memory in SMC-B has surpassed operator after the predefined time, SMC-B will have enough memory spaces to guarantee SMC-B automatically with this short message deletion, and so terminal B will can't receive this short message forever.
In actual life, the user often has the situation of temporarily using other number instead.For example when the user went on business, for saving communication cost, the user may use a local number temporarily.In this case, if the original number of user is in states such as shutdown or disengaging service area, the user can't receive the short message that sends to own original number, and these short messages will be by the short message service center of temporary cache in the original number home of user.
Simultaneously, because short message service center is in scope good for use for the memory space that guarantees self, need regular memory space to be optimized the short message that deletion is in buffer status for a long time, can't sends to self.So, the user may can't receive the part short message that sends to own original number after changing number forever, causes the serious consequence of the short-and-medium information drop-out of short message communication process.
