For making the object of the invention, technical scheme and advantage clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, to further explain of the present invention.
In order to solve prior art problems, system configuration of the present invention connects between short message service center and the logical platform of leakage words referring to shown in Figure 1.
Short message service center except that being used under portable terminal, the short-message sending, also being used for when receiving the failure code of the memory space inadequate that portable terminal returns, sending first notification message and gives the leakage words logical platform; And after receiving second notification message that Lou the logical platform of words returns, retransmit said short message to said portable terminal according to pre-configured retransmission mechanism.
Leak the logical platform of words, be used for after receiving first notification message of short message service center, initiate audio call to said portable terminal; After audio call is connected; Send the verbal announcement that the user deletes short message to said portable terminal, behind the end of conversation, send second notification message and give short message service center.
Wherein, short message service center can select to adopt the SS7 signaling interface mode of MAP or SMPP agreement to carry out data communication with the logical platform of leakage words.
The main flow process of the processing method during CDMA terminal short memory space inadequate of the present invention comprises: when short message service center under portable terminal during short-message sending, if said mobile terminal stores insufficient space then return failure code to short message service center; After receiving failure code, short message service center sends first notification message and gives the leakage words logical platform; Leak the logical platform of words and initiate audio call to said portable terminal; After audio call is connected, leak the logical platform of words and send the verbal announcement that the user deletes short message to said portable terminal; Behind the end of conversation, leak the logical platform of words and send second notification message to short message service center; Short message service center retransmits said short message according to pre-configured retransmission mechanism to said portable terminal.
Referring to shown in Figure 2, the embodiment of the short message service flow process between short message service center of the present invention (SMSC), the logical platform of leakage words, the user may further comprise the steps:
Step 201, short message service center is short-message sending under called subscriber's portable terminal.
Wherein, When short-message sending is to this short message service center home subscriber under the short message service center; At first need elder generation to belong to MSC with the SMSReq message of IS-41 MAP layer protocol to HLR inquiring user position, after HLR returned the GT sign indicating number of MSC, short message service center was issued to MSC with the SMDPP message of IS-41 MAP layer protocol with content of short message; MSC is sent to mobile phone through the base station with short message; When the mobile phone memory contents completely can't receive new short message, will return No. 35 mistakes and give MSC, MSC passes through short message service center with this error code through the smdpp response message.Therefore short message service center is when receiving No. 35 codes that MSC returns; Finish this time to issue; Continuation is retransmitted by the retransmission mechanism of the original configuration of short message service center; Different is to increase an extra processing procedure: extract this message calling number (mandatory field), called number (mandatory field), short message transmitting time (Optional Field), error code information field contents such as (Optional Fields); Coding generates a signaling message and sends to the Lou logical platform of words, sends the back and finishes this processing procedure, still continues to retransmit by former mechanism for former message.
Step 203, short message service center sends the first signaling message and gives the leakage words logical platform.
The said first signaling message can be selected following dual mode encoding process:
1) above-mentioned field information is pressed formed a SMDPP message after the MAP format encoded, be transmitted to words through the SS7 signaling interface with Louing and lead to platform.
2) above-mentioned field information is transmitted to the Lou logical platform of words by SMPP protocol format coding back through the SMPP connecting interface.
Step 204 is leaked the logical platform of words and is initiated audio call to the called subscriber.
Step 205, audio call is connected.
Step 206 is leaked the logical platform of words and is notified the user with voice mode, reminds the user to delete short message.
After the logical platform of leakage words is received the SMDPP or DELIVER_SM message from short message service center, can parse calling number (mandatory field), called number (mandatory field), short message transmitting time (Optional Field), error code information field contents such as (Optional Fields).
Call out called number then, it is full with voice mode prompting user mobile phone short message memory space to connect the back, has short message to issue, and please user (as 5 minutes) in some minutes delete useless short message, short message service center will be after 5 minutes short-message sending down.Configurable activation simultaneously informs that the called subscriber is the short message which calling number is sent.
Wherein, can in short message service center, dispose retransmission mechanism from said short message to said portable terminal that retransmit in advance.For example in the present embodiment, set retransmission mechanism was the time of short message delayed delivery, such as 5 minutes.
Issue in called subscriber's the verbal announcement, the said concrete time of asking the user in some minutes, to delete useless short message, preferably can be the time of said short message delayed delivery.
Step 207, after the called subscriber heard out voice suggestion, on-hook finished conversation.
Step 208 is leaked the logical platform of words and is taken out stitches.
Step 209 after the logical platform of leakage words is taken out stitches, is sent the second signaling message and is given short message service center.
After voice informing finishes; Finish voice call; Called number and verbal announcement deadline coding are generated a signaling short message; Contain calling number (mandatory field), called number (mandatory field), audio call concluding time (essential word selection section), send to short message service center with SMDPP message or SUBMIT_SM message bearing equally.If call failure, if then preferred configurablely make a call once more after at interval in a period of time is retry still after the failure again.The maximum attempts of retry is configurable, reach maximum attempts after.Stop retry.
Because sending the first signaling message, short message service center give the purpose of leaking the logical platform of words very clear and definite; Make and Lou talk about the critical fielies such as called number that logical platform can parse short message; Inform that with the mode of voice the called subscriber deletes the short message on the mobile phone, receive new short message so that have living space.Therefore after leaking the logical platform voice informing user of words; Need to send one second signaling message equally and give short message service center; Contain calling number, the called number in the short message equally in the second signaling signaling message, different is leaks the logical platform of words to issue what carry in the notification message of short message service center is the verbal announcement finishing time information.
Interface implementation method between short message service center and the logical platform of leakage words:
Short message service center can select to adopt the SS7 signaling interface mode of MAP or SMPP agreement to carry out data communication with the logical platform of leakage words.
Short message service center and leaking between the logical platform of words when connecting with Signaling System Number 7 (SS7) link mode.Short message service center to the message calling number (mandatory field) that extracts, called number (mandatory field), short message transmitting time (Optional Field), error code information field content carryings such as (Optional Fields) in the SMDPP of IS-41MAP layer protocol message; What need particularly point out is that short message transmitting time (Optional Field), error code (Optional Field) should be carried on the bearer data field; By the IS637 protocol encapsulation; Error code can directly be carried on the content of short message field chari with text mode, and short message transmitting time (Optional Field) or end of calling time (essential word selection section) are carried on the Deferred Delivery Time-Absolute field.
Short message service center and leaking between the logical platform of words when connecting with the SMPP agreement, short message service center leaks words and leads to platform as client as server end, should possess chain rupture and reconnect mechanism automatically.In the DELIVER_SM or SUBMIT_SM message of SMPP agreement, error code is carried on the content of short message field short_message to the message calling number (mandatory field) that extracts, called number (mandatory field), short message transmitting time (Optional Field), error code information field content carryings such as (Optional Fields) in short message service center.And short message transmitting time (Optional Field) or end of calling time (essential word selection section) are carried on the schedule_delivery_time field.
Step 210 is after the second signaling message is received by short message service center, according to predetermined retransmission mechanism short-message sending under called subscriber's portable terminal again.
In this step, after SMDPP or SUBMIT_SM signaling message are received by said short message service center, can judge further whether the source is to leak the logical platform of words, if not then handling by normal short message; If then carry out the fast message decoding by the field of the present invention's definition, extract called number and verbal announcement deadline, index according to called number and treat short-message sending, the short message of promptly said transmission failure.Whether the difference of judging current time and verbal announcement deadline meets or exceeds the said short message delayed delivery time, if, then retransmit said short message, continue to judge otherwise return up to meeting or exceeding the said short message delayed delivery time.
Above-described specific embodiment is merely specific embodiment of the present invention, is not limited to the present invention, and is all within spirit of the present invention and principle, any modification of being made, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
