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

Background technique

In the mobile short message service of GSM (Globa l System for Mobi le Communicated ions), in order to solve the problem of short message time display when sending messages between user terminals in different time zones, the standard protocol specification in GSM network Time zone information is defined in (3GPP TS 23. 040, 3rd Generation Partnership Project Standard 23.040), but because the capabilities of user terminals are different, some terminals do not parse during the process of receiving short messages. The field time zone field in the short message, the result is that the message time displayed to the user is incorrect, causing the user to misunderstand. In this case, the time adjustment can be performed by the SMS center according to different time zones. Usually, the same MSC (Mob i le Swi tching Center) is responsible for the same time zone, so that the time zone can be distinguished according to the MSC address. Before sending the short message, the SMS center first obtains the location of the called number of the short message by the HLR (Home Locating Regi s ter), and obtains the MSC address where the called number is located, and then the SMS center is based on the HLR. The obtained MSC address and the time zone information to which the MSC is configured in the short message center translates the time in the short message into the time zone of the called number, and the short message center processes the processed The short message is sent to the called number.

The inventor found that the technical solution is based on the premise that an MSC is only responsible for a user terminal in a time zone. Therefore, the technical solution itself has limitations. In practical applications, some small operators often use it for cost-saving reasons. An MSC is responsible for a relatively large area. At this time, an MSC is not only responsible for a user terminal in a time zone. In this case, the time zone information of the short message cannot be distinguished by simply relying on the MSC address. Summary of the invention

The SMS center first configures the correspondence between the cell identifier and the time zone. Before the short message is sent to the called number, the short message center obtains the called number by the ATI (any t ime informat ion enquiry) operation in the GSM protocol (3GPP TS 09. 02). Cell identity. For example, the short message center should send a short message to the user A of the cell i, and the short message center should configure the correspondence between the cell i and the time zone. The SMS center sends an ATI request message to the home location register, requesting to acquire the cell identity to which the user A belongs, and then the short message center receives the ATI response message returned by the home location register, and the response message indicates that the user A belongs to the cell i.

102. Convert, according to the obtained cell identifier to which the called number belongs, and the stored relationship between the cell identifier and the time zone, time information in the short message into time information corresponding to the time zone of the cell to which the called number belongs;

Cell identification time zone information

6831080678AB +8

6831080688 +9

6831080698 +7 In order to reduce the number of configuration data, the cell identification field can support the number segment configuration. User A belongs to the cell with the identifier 6831080688. It can be seen in the table configured by the SMS center that the cell ID to which the user A belongs corresponds to the +9 time zone.

302. The short message center sends an ATI request message to the home location register, and requests to obtain the cell identifier to which the called number belongs.

The SMS center can obtain information about the location and status of the terminal through the ATI operation. In the request message, the following parameters can be carried:

AnyTimelnterrogat ionArg :: = SEQUENCE {

Subscriber Identity [0] Subscriber Identity,

Requestedlnfo [1] Reques tedlnf o,

gsmSCF— Address [3] ISDN—AddressStr ing,

303. The short message center receives the ATI response message returned by the home location register, and the ATI response message returned by the home location register carries the cell identifier to which the called number belongs.

The cellldOrLAI field of the ATI response message carries the cell identity 6831080688 to which the user A belongs.

304. The short message center converts the time information in the short message into the time information of the time zone corresponding to the cell to which the called number belongs according to the obtained cell identifier to which the called number belongs and the stored relationship between the cell identifier and the time zone. In the configuration of the SMS center, the identifier is 6831080688. The cell corresponds to the +9 time zone. The SMS center should send a short message to the user A at 11:00 am. The time of the +9 time zone should be 12 am, then the SMS center. Convert the time in the short message to 12 am.

305. The short message center sends a routing message to the home location register, and requests to obtain a mobile switching center where the called number is located.

308. The short message center receives the confirmation message returned by the called number.

If the correct cell identifier is not carried in the ATI response message in step 303, the short message center retains the original time zone information, does not convert the short message time, and directly delivers the short message to the called number, so that even if the ATI operation fails. It also does not affect the processing of the normal process of short messages.

If the short message fails to be sent by the short message center and the short message needs to be resent in step 307, the ATI operation is not performed, and the short message is directly sent to the called number. Because if you need to re-transmit the short message every time to re-acquire the cell information, it will cause a large consumption of the system and signaling resources, and the chance of the user changing the short message during the retransmission process is small, so it is heavy. During the process, the ATI operation is no longer initiated.

When the user is registered to boot, it may be different from the time zone before the booting, as shown in Figure 4. The following operations are required:

401. The user initiates a registration operation to the home location register by using the mobile switching center where the user is located.

402. The home location register sends an Alert-Sc message to the short message center to notify the short message center. The user is turned on.

After the user is successfully registered, the HLR (Home Locating Registrar) sends an Alert_Sc message to the SMS center to notify the SMS center user to boot, and then the SMS center can send the SMS message to the user in the SMS center.

403. The short message center sends an ATI request message to the home location register, and requests to obtain the cell identity to which the user belongs.

404. The short message center receives the ATI response message returned by the home location register, where the ATI response message carries the cell identifier to which the user belongs.

405. The short message center converts the time information in the short message into the time information of the time zone corresponding to the current cell of the user according to the cell identifier to which the user belongs and the corresponding relationship between the stored cell identifier and the time zone.

406. The short message center sends a routing message to the home location register, requesting to obtain a mobile switching center where the user is located.

407. The short message center receives a route response message returned by the home location register, where the mobile switching center information of the user is included.

408. The short message center sends a short message to the mobile switching center where the user is located.

409. The short message center receives a confirmation message returned by the user.

In the embodiment of the present invention, before sending a short message to the user, the short message center first obtains the current cell identifier of the user through the ATI operation, and then converts the short message time into the time zone time corresponding to the cell identifier. The embodiment of the invention avoids the transformation of the existing network device, and the short message time can be converted through the short message center.
