Description

Routing information processing method, device and system

TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a routing information processing method, apparatus, and system. BACKGROUND OF THE INVENTION Short Message System (referred to as SMS) is a third generation partnership program (3rd)

A non-real-time communication system proposed by the Generation Partnership Project (3GPP). The system mainly includes a short message service center (SMS Service Center, SMS-SC for receiving short messages from user equipment or other devices). The short message sent by the user is called a short message (MO-SM), and is stored and forwarded to the target. The target may be a terminal device (including a user device) or an application server (targeting the terminal device). The short message, called the terminating short message, is referred to as MT-SM. A network control unit (for example, a Mobile Switching Center (MSC)) or a General Packet Radio Service (GPRS) support node (Serving) The GPRS Support Node (hereinafter referred to as SGSN) or the Mobile Management Entity (MME) is forwarded to the terminal device, and may also be forwarded to the terminal device through the IP network by the IP short message gateway (referred to as IP-SM-GW). . The short message system can provide a messaging platform for other applications. For example, the machine type communication uses a Machine Type Communication Inter Working Function (MTC-IWF) to interact with the SMS-SC to implement the terminal through the short message. The trigger of the app. 1 is a flowchart of a routing process of a machine type communication message according to the related art. As shown in FIG. 1, the process steps are as follows: Step S102: The MTC-IWF is directed to a Home Location Register (HLR) or attribution. The Home Subscriber Server (HSS) sends an inquiry routing message carrying the receiver information, for example, sending a Subscriber Information Request message carrying the recipient number. Step S104: The HLR or the HSS sends a routing information message to the MTC-IWF, for example, sends a Subscriber Information Response message, and carries the routing information. Step S106: The MTC-IWF sends a message to the receiver through the SMS-SC, for example, sends a Submit Trigger message, and the message carries the obtained routing information. Step SI 08: The SMS-SC sends a message to the SMS-GMSC, for example, sending an SMS-Deliver message carrying the obtained routing information. Step S110: The SMS-GMSC has obtained the routing information, and therefore no longer sends an inquiry routing message to the HLR or the HSS. The SMS-GMSC forwards the message to the MSC or the SGSN or the MME according to the routing information, for example, sends a MAP_MT_Forward_SMS request message, and the message carries the receiver. Information, for example, International Mobile Subscriber Identity (IMSI). Step S112: The MSC or the SGSN or the MME forwards the message to the receiver, for example, sends a Transfer Message message. It can be seen that in the machine type communication message routing method in the related art, if the message fails to be sent, the SMS-SC stores the message, and waits for the receiver to report the notification of the receivable message and then resends the message, and during this time The terminal is likely to move the location.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. This embodiment provides a routing information processing method. FIG. 2 is a flowchart of a routing information processing method according to an embodiment of the present invention. As shown in FIG. 2, the method includes the following steps: Step S202, a first machine type communication interaction The function (MTC-IWF) receives the association identifier sent by the second MTC-IWF through the short message service center (SMS-SC) and the short message gateway mobile switching center (SMS-GMSC); step S204, the first MTC-IWF is according to the above The association identifier obtains routing information, and sends the routing information to the SMS-GMSC. In this embodiment, the second MTC-IWF carries the association identifier when sending the message to the SMS-SC and triggers the SMS-SC to send the message to the SMS-GMSC, so when the SMS-GMSC forwards the message, it cannot identify the association. The identifier is not valid route information, so the association identifier needs to be sent to the first MTC-IWF to query the routing information. The first MTC-IWF can obtain the routing information according to the association identifier and send the routing information to the SMS-GMSC, so that the SMS - When the GMSC fails to forward the message and forwards it again, it needs to re-acquire the routing information by using the association identifier, thereby updating the routing information, and solving the problem that the forwarding message cannot be sent to the receiver due to the use of the incorrect route to send the message in the related art, and the message is improved. The reliability of the transmission. In combination with other network elements, the process may be described as follows: The second machine type communication interaction function (MTC-IWF) requests the short message service center (SMS-SC) to send a message carrying the association identifier; a home location register (HLR) or a home subscription server (HSS) forwarding the query routing message carrying the associated identifier to the first MTC-IWF; the first MTC-IWF obtains the routing information and returns. In the case where there is no multiple MTC-IWF, the first MTC-IWF is the second MTC-IWF. Considering that there may be multiple cases of the MTC-IWF, for example, in a distributed system, the first MTC-IWF may go to other All the MTC-IWFs send the association identifiers to query the association information, so that the association information can be obtained from the second MTC-IWF. Preferably, the association identifier includes the second MTC-IWF information, so that the SMS-GMSC can go to the second. The MTC-IWF sends the association identifier such that the first MTC-IWF is the second MTC-IWF. By including the information of the MTC-IWF in the association identifier, the SMS-GMSC can conveniently find the corresponding MTC-IWF when inquiring the routing information, which saves processing time and improves processing speed. In order to make the routing information acquired by the first MTC-IWF according to the association identifier is up-to-date, the first MTC-IWF may obtain routing information of the message from the HLR or the HSS according to the association identifier. When the message is sent for the first time, since the message fails to be sent and the process of waiting, the routing information is usually correct. To improve efficiency, the first MTC-IWF can receive the association identifier for the first time. According to the association identifier, the routing information is obtained from the local storage, and when the association identifier is received subsequently, the routing information is obtained from the HLR or the HSS. Preferably, the step S204 may include: the MTC-IWF sends the routing information to the SMS-GMSC through the HLR or the HSS, or directly sends the routing information to the SMS-GMSC, which may depend on whether the network deployment condition and the signaling protocol are consistent. . As a preferred implementation manner, the association identifier may be associated with the receiver information, or the sender information, or the routing information, or a combination thereof. For example, the receiver information may be a number or an international mobile station identifier.

The following description is made in conjunction with the preferred embodiments, each of which combines the above-described embodiments and preferred embodiments thereof. The following is an example of use in a machine type communication and short message system, and provides a routing method and system for machine type communication messages. In the implementation process, the following two methods can be used: Mode 1: The first MTC-IWF receives the association identifier sent by the second MTC-IWF through the SMS-SC and the SMS-GMSC, and the association identifier can be forwarded by the HLR or the HSS. The first MTC-IWF obtains routing information and returns it to the SMS-GSMC; the SMS-GMSC forwards the message from the SMS-SC according to the routing information. Manner 2: The SMS-SC receives a message sending request from the MTC-IWF carrying the routing information; the SMS-SC fails to send the message, where the message sets the routing information; the SMS-SC sets the routing information to be invalid for the message. Embodiment 1 In the preferred embodiment, a process in which an MTC-IWF sends a message to a receiver through an SMS-SC is described. FIG. 14 is a schematic flowchart of a machine type communication message routing according to Embodiment 1 of the present invention, as shown in FIG. The process steps are as follows: Step S1402: The MTC-IWF sends an inquiry routing message to the HLR or the HSS, carrying the receiver information, for example, sending a Subscriber Information Request message carrying the recipient number. Step S1404: The HLR or the HSS sends a routing information message to the MTC-IWF, for example, sends a Subscriber Information Response message, and carries the routing information. Step S1406: The MTC-IWF assigns an association identifier C-ID, and the C-ID may be associated with the receiver information, or may be associated with the routing information, or may be associated with the sender information, and may also associate their combinations, in particular, C - When the ID is associated with the recipient information, it can be the recipient number or identifier. Step S1408: The MTC-IWF sends a message to the SMS-SC, which carries the C-ID. For the case of multiple MTC-IWFs, the association identifier C-ID may also include information of the MTC-IWF, for example, a Submit Trigger message may be sent. Step S1410: The SMS-SC sends a message to the SMS-GMSC. For example, an SMS-Delivery message may be sent, and the message carries a C-ID. Step S1412: The SMS-GMSC sends an inquiry message to the HLR or the HSS. For example, the MAP SRI For SM request message may be sent, and the message carries the C-ID. Step S1414: The HLR or HSS forwards the inquiry message to the MTC-IWF, carrying the C-ID. In step S1414, there may be another embodiment in which the SMS-GMSC may directly send a message to the MTC-IWF carrying the C-ID. The MTC-IWF that sends the association identifier may not be the MTC-IWF that receives the association identifier. In this case, a distribution mechanism needs to be deployed, such as providing the MTC-IWF coordinator, so that the MTC-IWF receiving the association identifier can be obtained from the MTC-IWF that sends the association identifier. The associated information, such as the MTC-IWF that sends the C-ID through the MTC-IWF coordinator and requests associated information from it. Step S1416: The MTC-IWF obtains routing information according to the C-ID. For example, the HLR or the HSS may be queried according to the receiver information (such as IMSI information) associated with the C-ID, or directly when the C-ID is received for the first time. The associated routing information is returned, and the HLR or HSS is queried for routing when subsequently received. Step S1418: The MTC-IWF sends the routing information to the SMS-GMSC. For example, the MAP SRI For SM response message may be sent, and the message may pass through the HLR or the HSS, depending on the network deployment situation or whether a protocol conversion is required. Step S1420: The SMS-GMSC has obtained the routing information, and therefore no longer sends an inquiry routing message to the HLR or the HSS. The SMS-GMSC forwards the message to the MSC or the SGSN or the MME according to the routing information, for example, sends a MAP_MT_Forward_SMS request message, and the message carries the receiver. Information, for example, IMSI. Step S1422: The MSC or the SGSN or the MME forwards the message to the receiver, for example, sends a Transfer Message message. From the above description, it can be seen that the preferred embodiment achieves the following technical effects: By updating the routing information, the problem that the forwarding message cannot be sent to the receiver due to the use of the wrong route to send the message in the related art is solved, and the message is improved. The reliability of the transmission. Embodiment 2 This preferred embodiment describes a process in which an MTC-IWF sends a message to a receiver through an SMS-SC. FIG. 15 is a schematic flowchart of a machine type communication message routing according to Embodiment 2 of the present invention, as shown in FIG. The process steps are as follows: Step SI 502: The MTC-IWF sends an inquiry routing message to the HLR or the HSS, carrying the receiver information, for example, sending a Subscriber Information Request message carrying the recipient number. Step S1504: The HLR or the HSS sends a routing information message to the MTC-IWF, for example, sends a Subscriber Information Response message, and carries the routing information. Step S1506: The MTC-IWF sends a message to the receiver through the SMS-SC, for example, sends a Submit Trigger message, and the message carries the obtained routing information. Step S1508: The SMS-SC sends a message to the SMS-GMSC, for example, sends an SMS-Deliver message, and the message sets routing information, for example, carries the obtained routing information in the message, or the SMS-SC moves to the short message gateway mobile switching center.
