Description

A method of transmitting a message

TECHNICAL FIELD The present invention relates to the field of communications, and in particular, to a method for transmitting a message.

BACKGROUND With the rise and development of various IP access technologies, how to transform an existing mobile network service into a service that an IP terminal can provide has become a target of the Third Generation Partnership Project (3GPP) standardization organization. . For example: Short Message Service (SMS) service is considered to be one of the most important and widely used services in the current mobile network, but there is no good solution for implementing short message service in IP transmission based networks. Considering that IP-based access networks are becoming more and more popular, such as wireless local area networks (WLANs), next-generation networks (NGNs), etc., for various IP terminals, or multimodes that support IP access methods and mobile network access methods. Terminals, such as WLAN and WCDMA/GSM multimode terminals, how to reuse existing mobile network short message service functional entities and protocols as much as possible, and access to the mobile core network through IP-based access networks, is also a common concern of operators. The problem.

FIG. 1 is a network framework for implementing short message service by an IP terminal proposed by the 3GPP, where a short message device (SME), a short message service center (SM-SC), a mobile switching center gateway/short message interworking mobile switching center (GMSC/SMS- The IWSMSC), the home subscriber network/home location server (HSS/HLR) is a functional entity for the existing mobile network to implement the SMS service. The SM-SC is used to store short messages; the GMSC is used to query the HSS/HLR for routing information when the terminal receives the short message; and the SMS-FWMSC is used for authentication when the terminal sends the short message. At present, the short message centers applied in the network are all devices integrating SM-SC, GMSC and SMS-IWMSC, and the three functional entities are not implemented as separate physical devices. In Figure 1, only IP-MESSAGE-GW is a new network entity that implements communication between the IP client and the GMSC/SMS-IWMSC, and requires IP network messaging protocols (such as IP Multimedia Messaging Protocol) and existing WCDMA/ Interworking between GSM short message protocols. The IP-MESSAGE-GW communicates with the GMSC/SMS-IWMSC through the MAP protocol, similar to the communication between the MSC and the SGSN and the GMSC/SMS-IWMSC; the IP-MESSAGE-GW communicates with the IP client through IP. When a user who supports IP access applies a short message service, First registered to IP-MESSAGE-GW, IP-MESSAGE-GW informs HSS of the user's registration status and IP-MESSAGE-GW address, HSS saves the user status and the IP-MESSAGE-GW address of the user.

In the prior art solution, when the short message center transmits the message to the IP message gateway, the IP message gateway sends a message to the IP-based terminal, and if the sending fails, the message transmission failure report is returned to the short message center; then the short message center according to the terminal The ability selects another suitable way to send a short message to the terminal.

After all the short messaging attempts (SMS-MT) (through MSC, SGSN and IP-MESSAGE-GW) fail, the message is stored in the SM-SC. When the terminal resumes the connection, the Alert process is performed to notify the SM. - The SC sends a message, as shown in Figure 2, including the following steps:

1. All SMS-MTs (through MSC, SGSN and IP-MESSAGE-GW) fail (for example, because the UE is out of reach), the messages transmitted to the IP-based terminals are queued in the SM-SC.

2. The registration/re-registration process based on the IP terminal initiation criteria (for example, restoring the IP connection with the WLAN).

3. If the HLR/HSS receives the registration request based on the IP terminal, and the message waiting flag is set, the BJHLR/HSS sends a MAP-Alert-SC request message with the SM-SC address list to the SMS-GMSC.

4. The GMSC sends a SC Alert request message to the SM-SCs in the SM-SC address list. The current IP-based message-based standard lacks proper handling of messages that cannot be received because the terminal memory is full. According to the current technical requirements, if the method fails based on the IP transmission, a failure is returned, and the message center attempts other ways to send a message to the terminal. However, in the case where the terminal memory is saturated, the terminal cannot receive the message regardless of the method used to transmit the message. Such an attempt can only increase the network burden, but it does not achieve any desired results.

Summary of the invention

The object of the present invention is to improve the solution and processing of an abnormal situation based on an IP transmission message system, and provide a method for transmitting a message to an IP-based terminal to improve network utilization. Rate.

To this end, the present invention adopts the following technical solutions:

B. If the IP terminal is unable to receive the message, the message is sent to the message center through the IP message gateway, and the failure reason is carried in the message failure message;

C. The message center determines whether the message transmission failure occurs because the memory space of the IP terminal is insufficient, and if it is, the process proceeds to step D, if no, the process proceeds to step E;

D. The message center sends a message transmission report to the home location register/home subscriber network server;

E. The message center attempts other ways to send a message to the IP-based terminal.

Before the step A, the method further includes the step A1: registering or re-registering based on the IP terminal.

In the step B, the method further includes the following steps:

Bl, determining whether the IP terminal receives the message, if it is a return success message, if not, proceed to step B2;

B2, determining whether the reason for the failure is based on the IP terminal storage space is full, if it is to proceed to step C, if not proceed to step B3;

B3. Resending the message to the IP-based terminal, if the IP terminal receives the message, returning a success message, otherwise, repeatedly sending the message to the IP-based terminal until the time or number of times the IP message gateway sets the message to be sent, IP The message gateway sends a message failure message to the message center, and carries the failure reason in the message failure message.

In the step C, the IP terminal-based memory space is insufficient, and the memory full memory and memory available space based on the IP terminal are insufficient to store the message sent this time.

The method further includes the steps of:

F. when the IP terminal storage space can receive the message, notify the home location register/home subscription user server; G. The home location register/home subscriber network server notifies the message center to send the message.

In the step E, the other manners include sending a message through the mobile switching center and sending a message through a gateway GPRS function node (GGSN).

The message is a short message or a multimedia message.

The method is characterized in that, in the IP-based terminal, whether a storage space is full, or not, is used to identify whether the storage space based on the IP terminal is full.

The present invention improves the resolution and processing of an abnormal situation based on the IP transmission message system by adding an exception handling process that cannot receive a message due to insufficient storage space of the IP terminal. It also improves the processing process when the terminal has the ability to receive messages, which simplifies the network processing content and improves network utilization.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings.

The invention simplifies the processing of the network in this case, improves the network utilization rate, and improves the IP-based transmission, because the exception processing based on the IP terminal memory is full, and the processing procedure when the IP-based terminal has the receivable message is simplified. The message system solves and handles the abnormal situation.

The present invention sets a storage identifier on the IP terminal side to identify whether the storage space based on the IP terminal is full. In the process of receiving a message based on the IP terminal, the corresponding process may be triggered according to the state of the storage identifier. As shown in FIG. 4, the solution of the present invention specifically includes the following steps:

Sll, a standard registration/re-registration process based on the IP terminal;

The process is actually to verify that the IP-based terminal is on the network and can apply the network's messaging service, whether wireless or fixed.

S12. The message center sends a message to the IP gateway.

When the message center extracts the routing information from the HSS, it should indicate that the IP message is supported. When the address of the IP message gateway is received and the message is transmitted through the IP, the message is sent to the IP message gateway.

513. The IP message gateway transmits the message to the IP-based terminal.

If the storage identifier of the IP terminal is full, the message cannot be received due to insufficient storage space of the IP terminal, and a message sending failure response message is returned, and the reason for the failure of the message transmission is carried in the response message.

In this step, a step of repeating the message transmission through the IP message gateway can be further set.

After the message is transmitted to the IP-based terminal through the IP message gateway, if the message is not sent due to insufficient storage space of the IP-based terminal, the IP message is used to transmit the message when the IP resource is used. After receiving the transmission failure response message, the message is sent again. If the retransmitted message cannot be received by the IP terminal after reaching the specified number of times or time, the flow is performed downward.

514. The IP message gateway sends a response message carrying the reason for the failure to the message center.

The IP message gateway sends a response message to the message center, and the response message carries a failure reason. In this embodiment, the reason for the failure is based on insufficient storage space of the IP terminal.

S15. The reason why the message center determines the response message carrying the reason for the failure;

The message center extracts the reason for the failure of the message carried in the response message, and makes a judgment.

S16. If the message cannot be delivered due to insufficient storage space of the IP terminal, the message center transmits a message transmission report status to the HLR/HSS; and stores the message according to requirements.

Because the message transmission failure is due to insufficient storage space of the IP terminal, the message center transmits a message transmission report to the HLR/HSS, reports related information of the failure of the current message transmission, and simultaneously stores the message that failed to be transmitted, so as to be based on the IP. The terminal has received the message When the condition is met, resend.

517. When the information can be received based on the storage space of the IP terminal, notify the IP message gateway.

518. The IP message gateway notifies the HLR/HSS that the message can be received based on the IP terminal storage space. When the storage space of the IP terminal is available and one or more messages can be received, the state of the storage identifier is that the storage space is available, and the IP message gateway is used. Notify the HLR/HSS to initiate the process of resending the message.

519. When the HLR/HSS receives the message based on the storage space of the IP terminal, the alert transmission process is performed with the message center.

In the solution of the present invention, the content of the message may be a short message, a multimedia message, or the like.

The following is an implementation of the solution in the network in which the SM-SC, the SMS-GMSC, and the IP-CAN are respectively used as the network function entities. In this embodiment, the short message is used to describe the solution of the present invention, which specifically includes the following steps:

S21. Perform a standard registration/re-registration process based on the IP terminal;

S22. The short message center transmits a message to the SMS-GMSC.

S23. When the SMS-GMSC extracts routing information from the HSS, it shall instruct the SMS-GMSC to support the IP message. The SMS-GMSC may receive and process the three E.164 addresses of the MSC, SGSN, and IP-Message-GW. If the SMS-GMSC selects "SMS over IP", the SMS-GMSC sends a short message to the IP-Message-GW;

S24. The IP-Message-GW transmits the short message to the IP-based terminal. For some reason, the short message cannot be received. If the storage space is not full based on the IP terminal, the message is resent once, and if the message is resent, the specified number of times is reached. If the message still fails to be received after the time, the message is sent with a failure response message, and the response message carries the reason for the failure;

S25. The IP-Message-GW sends a response message carrying the reason for the failure to the SMS-GMSC. S26. The SMS-GMSC determines the cause of the response message carrying the failure cause.

If the message cannot be delivered due to insufficient storage space of the IP terminal, proceed to step 7;

If the message is not available for other reasons (for example, based on the IP terminal cannot be reached) After the delivery, the other way is to perform the message delivery attempt process.

527. The SMS-GMSC transmits an SM transmission report status to the HLR/HSS.

528. The SMS-GMSC transmits a report to the SM-SC, and the SM-SC stores the message according to the requirement;

529. When the IP terminal storage space is available and can receive one or more short messages, notify the IP message gateway.

5210, IP message gateway notification HLR/HSS can receive and receive based on IP terminal storage space

5211. When the HLR/HSS receives a message that is available based on an IP terminal storage space, sending a MAP-Alert-SC message with an SM-SC address list to the SMS-GMSC.

S212. The SMS-GMSC sends a SC Alert request message to the SM-SC in the SM-SC address list to notify the SM-SC that the storage space based on the IP terminal is available.

The technical solution of the invention improves the solution and processing of the abnormal situation based on the IP transmission message system. Increasing the processing of exceptions due to the inability to receive messages based on the IP terminal memory being full and the processing when the terminal has the receivable messages, simplifying the processing of the network in this case and improving network utilization.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. All modifications, equivalents, improvements, etc., made within the spirit and scope of the invention are intended to be included within the scope of the appended claims.
