A message forwarding method

technical field

The invention relates to message processing technology, in particular to a message forwarding method, system and short message center.

Background technique

With the rapid update of electronic and communication technologies, communication networks can provide users with more and more services, and the experience brought by these services to users is getting better and better. Take the messaging service as an example. Currently, hundreds of millions of users use messaging as a common communication tool. From the perspective of the user terminal, the calling user only needs to input the number of the called user and the content of the message to be transmitted on a terminal such as a mobile phone, and then the content of the message can be sent to the terminal through a wired or wireless communication network. to the called user. From the perspective of the network side, after the message arrives at the message storage and forwarding device such as the short message center from the calling user, it passes through network devices including service gateways or Internet gateways, and then reaches the service provider or the network where the called user is located.

FIG. 1 shows a signaling flow chart of a message forwarding method using a short message center as an example of a message store and forward device. Referring to Figure 1, the method includes:

In steps 101-102, the calling user submits a message to be transmitted to the short message center, and the short message center returns a message reception response to the calling user, indicating that the message submitted by the calling user has been received.

In steps 103-105, the short message center forwards the message from the calling user to the lower-level network equipment, and the lower-level network equipment returns a response to receiving the message to the short message center, indicating that the message submitted by the short message center has been received, and the lower-level network equipment Forward the received message to the service provider.

In steps 106-107, after receiving the message reception response from the lower-level network device, the short message center generates a receipt and sends it to the calling user, and the calling user returns the receipt response to the short message center.

So far, the existing message forwarding process is completed.

In the process described above, after receiving the received message response from the lower-level network equipment, the short message center immediately returns a receipt to the calling user. After receiving the receipt, the calling user thinks that the message has been sent to the called user, but the actual situation After the short message center sends the receipt, the lower-level network equipment is still scheduling network resources, message packets, etc., and the message from the calling user has not reached the called user. In this way, the receipt received by the calling user cannot truly indicate that the message has been delivered to the called user, that is, the receipt is a false receipt, which cannot reflect the real situation of message transmission to the user, affecting service quality and user experience.

Detailed ways

In order to make the purpose and technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

The present invention is a message forwarding method, the basic idea of which is: when the short message center forwards the message from the calling user to the intermediate network device, it indicates that a return receipt is required, and the intermediate network device or the interconnection device successfully forwards the message to the called party. After calling the user, send a receipt to the short message center.

Fig. 2 shows an exemplary flowchart of a message forwarding method in the present invention, referring to Fig. 2, the method includes:

In step 201, the calling user submits the message that needs to be transmitted to the called user to the short message center, and the short message center requests a return receipt when forwarding the received message to the intermediate network device;

In step 202, after the intermediate network device successfully sends the received message to the called user, it sends a receipt indicating successful sending to the calling user through the short message center.

Fig. 3 shows a system for executing the above message forwarding process in the present invention. Referring to Fig. 3, the system includes: a short message center and an intermediate network device, wherein the short message center is used to receive the message from the calling user, forward the received message to the intermediate network device and request a return receipt, and receive the message from the intermediate The receipt of the network device, and forward it to the calling user; the intermediate network device is used to receive the message from the short message center and the request indicating the return receipt, send the received message to the called user, and send it to the called user after the sending is successful. The short message center sends a receipt.

In the present invention, the intermediate network device may be a lower-level network device or an interconnection device. When the called user is a service provider in the same network as the calling user, the short message center forwards the message through the lower-level network equipment, and the lower-level network equipment sends the received message to the service provider; when the called user is in the same network as the calling user When the called user is in a different network, the short message center forwards the message through the interconnection device, and the interconnection device sends the received message to the network where the called party is located. The message forwarding method and system of the present invention will be described below through two embodiments.

Example 1

In this embodiment, the called user is a service provider in the same network as the calling user, and the service provider connects to the short message center through a lower-level network device such as a service gateway and a proxy device for service access.

Fig. 4 shows a signaling flowchart of the message forwarding method in this embodiment. Referring to Figure 4, the method includes:

In steps 401-402, the calling user submits a message to be transmitted to the short message center, and the short message center returns a message reception response to the calling user, indicating that the message submitted by the calling user has been received.

The message here includes short message content, signaling control information and other types of messages. When the calling user needs to send a short message to the called user, the calling user first enters the content of the message and the called number indicating the identity of the called user on the terminal used, and then sends the message and the called number to the network side. After receiving the message and the called number, the short message center on the network side returns to the calling user a response indicating that the short message center has successfully received the message.

In steps 403-404, the short message center forwards the message from the calling user to the lower-level network device, and requests the lower-level network device to return a receipt after the message is successfully transmitted, and the lower-level network device returns a message response to the short message center, indicating The message submitted by the short message center is received.

In this embodiment, in order to accurately reflect the transmission of the message, when the short message center sends the caller's message to the lower-level network device, it requests the lower-level network device to return a receipt after successfully transmitting the message. Here, the short message center may set the value of the return receipt-related information element in the signaling message carrying the calling user's message as a value indicating that a return receipt needs to be returned. For example, when the short message center forwards the message through the DELIVER_SM or DATA_SM message of the SMPP protocol, the value of the registered delivery (registered_delivery) information element in the above message is set to a value indicating that a receipt needs to be returned. Specifically, a certain bit in the IE can be determined to indicate whether to return a receipt, and setting the value of this bit to 1 indicates that the short message center needs a receipt. Assuming that the last bit indicates whether to return a receipt, when the cell is 0xxxxxxxx1, it indicates that the short message center needs to return a receipt, and the x indicates that this bit is not to be checked when determining whether to return a receipt.

After the subordinate network device receives the message of the short message center, it is determined that the short message center needs to return a receipt, and then assigns a message identifier (message_id) for the message, so that when the return receipt is returned to the short message center in the subsequent steps, it will be used for the receipt of the short message center. targeted message. Then, the lower-level network device sends the message_id to the short message center by receiving the message response. Certainly, the short message center may also assign a message_id to the calling user's message, and submit it to the lower-level network device when sending the calling user's message to the lower-level network device. Correspondingly, when the lower-level network device returns a message reception response, it also carries a message_id, indicating that the message corresponding to the message_id has been received.

In addition, in order to ensure the safety of the message transmission process, after receiving the message from the calling user, the short message center first performs legality checks such as authentication, and then forwards it.

In steps 405-406, the lower-level network device forwards the received message to the service provider, and the service provider returns a response to the received message to the lower-level network device.

In this embodiment, the service provider as the called user is connected to the lower-level network equipment. When the service provider receives the message of the calling user from the lower-level network equipment, it indicates to the lower-level network equipment that the message has been received by receiving the response message. Successfully reached the service provider.

In steps 407-408, after receiving the message response from the service provider, the lower-level network device generates a receipt corresponding to the message, and sends the generated receipt to the short message center, and the short message center sends the message to the lower-level network device. Return receipt response, indicating receipt.

Here, when the lower-level network device generates the receipt, in order to facilitate the short message center to distinguish the message corresponding to the receipt, the message_id assigned to the message in step 403 or 404 is carried in the receipt.

In steps 409-410, after receiving the receipt from the lower-level network equipment, the short message center determines the message and the calling user corresponding to the receipt, and sends the received receipt to the calling user, and the calling user then Return the receipt response to the short message center.

When the short message center receives the receipt sent by the lower-level network equipment, it parses the message_id from the receipt, and sends the received receipt to the determined caller according to the message corresponding to the message_id and the calling user who sent the message. Call the user. In this case, the receipt received by the calling user really indicates that the sent message has successfully reached the called user.

So far, the message forwarding process in this embodiment is completed.

In this embodiment, when the short message center forwards the message to the lower-level network equipment, it indicates that a receipt indicating that the message is successfully sent to the called user is required, and then the lower-level network equipment returns the receipt to the calling user through the short message center after the transmission is successful. . It can be seen that the receipt in this embodiment is an accurate receipt that can truly indicate that the message has been successfully sent. In this way, the calling user can confirm that the message has reached the called user according to the received receipt, thereby effectively improving the network service quality and user experience.

Example 2

In this embodiment, the called user and the calling user are in different networks, and the network where the called user is located is connected to the short message center through an interconnection device such as an Internet gateway or an entity with an interconnection function.

Fig. 5 shows a signaling flowchart of the message forwarding method in this embodiment. Referring to Figure 5, the method includes:

In steps 501-502, the calling user submits a message to be transmitted to the short message center, and the short message center returns a message reception response to the calling user, indicating that the message submitted by the calling user has been received.

In steps 503-504, the short message center forwards the message from the calling user to the interconnected device, and requests the interconnected device to return a receipt after the message is successfully transmitted, and the interconnected device returns a message response to the short message center, indicating that the short message has been received. A message submitted by the message center.

In this embodiment, after the interconnected device receives the message from the short message center, the message is allocated message_id by the short message center or the interconnected device as in embodiment 1, so that when returning a receipt to the short message center in the subsequent steps, the short message can be provided. The message that the hub returns for.

In steps 505-506, the interconnected device forwards the received message to the network where the called user resides, and the network where the called user resides returns a message response to the interconnected device after the message is transmitted to the called user.

In this embodiment, since the called user is located in another network, the message first arrives at the network where the called user resides from the interconnected device, and then is forwarded to the called user by the network where the called user resides. Only after the network where the called party is located determines that the called user has received the message, does the response of receiving the message be returned to the interconnected device.

In steps 507-508, after receiving the message response from the network where the called user is located, the interconnected device generates a receipt corresponding to the message, and sends the generated receipt to the short message center, and the short message center sends a message to the interconnected device Return receipt response, indicating receipt.

Here, when the interconnected device generates the receipt, in order to facilitate the short message center to distinguish the message corresponding to the receipt, the message_id assigned to the message in step 504 is carried in the receipt.

In steps 509-510, after receiving the receipt from the interconnected device, the short message center determines the message corresponding to the receipt and the calling user, and sends the received receipt to the calling user, and the calling user sends the The receipt response is returned to the short message center.

The operations here are exactly the same as steps 409-410 in Embodiment 1.

So far, the message forwarding process in this embodiment is completed.

Similar to Embodiment 1, the receipt in this embodiment can also truly indicate that the message is sent successfully. In this way, the calling user can confirm that the message has reached the called user according to the received receipt, thereby effectively improving the network service quality and user experience.
