Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a system for processing routing information.
Background
A Short Message System (SMS) is a non-real-time communication System proposed by the third generation Partnership Project (3 GPP), and mainly includes a Short Message Service Center (SMS Service Center, SMS-SC) for receiving Short messages sent from a user equipment or other devices (called originating Short messages, MO-SM for Short) and storing and forwarding the Short messages to a target, which may be a terminal device (including a user equipment) or an application server (called terminating Short messages, MT-SM for Short when the target is a terminal device). The terminating short message is forwarded to the terminal device through a network control unit (e.g., a Mobile Switching Center (MSC), a Serving General Packet Radio Service (GPRS) Support Node (SGSN), or a Mobile Management Entity (MME), of a network to which the terminal device is accessed, or may be forwarded to the terminal device through an IP network by an IP short message gateway (IP-SM-GW).
The short message system may provide a messaging platform for other applications, such as Machine Type Communication (MTC) for interacting with SMS-SC using MTC, so as to trigger the terminal application through short message. Fig. 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 steps of the process are as follows:
step S102: the MTC-IWF sends an inquiry routing message, carrying receiver Information, e.g., a Subscriber Information Request message, carrying a receiver number, to a Home Location Register (HLR) or a Home Subscriber Server (HSS).
Step S104: the HLR or HSS sends a routing information message to the MTC-IWF, for example, a SubscriberInformationResponse message is sent, which carries routing information.
Step S106: and the MTC-IWF sends a message to a receiving party through the SMS-SC, for example, sends a Submit Trigger message, and the message carries the obtained routing information.
Step S108: the SMS-SC sends a message to the SMS-GMSC, e.g. 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 HSS, and the SMS-GMSC forwards a message to the MSC or SGSN or MME according to the routing information, e.g., sends a MAP _ MT _ Forward _ smsreq message, which carries the recipient information, e.g., International Mobile Station Identity (IMSI).
Step S112: the MSC or SGSN or MME forwards the Message, e.g. sends a Transfer Message, to the recipient.
It can be seen that, in the routing method of the machine type communication message in the related art, if the message transmission fails, the SMS-SC stores the message, and retransmits the message after waiting for the notification that the receiving party can receive the message, and during this time, the terminal is likely to move the location, and at this time, the forwarded message cannot be transmitted to the receiving party due to the use of the wrong route.
An effective solution is not provided at present for the problem caused by using a wrong route to send the message in the related art.

Detailed Description
The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The present embodiment provides a routing information processing method, and 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 interactive function (MTC-IWF) receives an associated identifier sent by a second MTC-IWF through a short message service center (SMS-SC) and a short message gateway mobile switching center (SMS-GMSC);
and step S204, the first MTC-IMF acquires the routing information according to the association identifier and sends the routing information to the SMS-GMSC.
Through the above steps, 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, since the association identifier cannot be identified, the effective routing information cannot be obtained, the association identifier needs to be sent to the first MTC-IWF to inquire about the routing information, and 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-GMSC needs to re-obtain the routing information by using the association identifier when forwarding the message again fails, thereby updating the routing information, solving the problem caused by using an incorrect route to send the message in the related art, and improving the reliability of message sending.
In combination with other network elements, the process may be described as: a second machine type communication interactive function (MTC-IWF) requests a short message service center (SMS-SC) to send a message, and the message carries an associated identifier; a Home Location Register (HLR) or a Home Subscription Server (HSS) forwards an inquiry routing message carrying the association identifier to the first MTC-IWF; and the first MTC-IWF acquires the routing information and returns the routing information.
Considering the case that there may be multiple MTC-IWFs, for example, in a distributed system, the first MTC-IWF may send an association identifier to all other MTC-IWFs to query for association information, so as to obtain the association information from the second MTC-IWF, and preferably, the association identifier includes the second MTC-IWF information, so that the SMS-GMSC may send the association identifier to the second MTC-IWF, so that the first MTC-IWF is the second MTC-IWF. By the mode that the MTC-IWF information is contained in the associated identification, the SMS-GMSC can conveniently find the corresponding MTC-IWF when inquiring the routing information, thereby saving the processing time and improving the processing speed.
In order to make the routing information acquired by the first MTC-IMF according to the association identifier latest, the first MTC-IMF may acquire the 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, because no process of message sending failure and waiting occurs, the routing information at this time is still correct, and in order to improve efficiency, when the first MTC-IMF receives the association identifier for the first time, the first MTC-IMF may first obtain the routing information from the local storage according to the association identifier, and when the association identifier is received later, obtain the routing information from the HLR or the HSS.
Preferably, step S204 may include: the MTC-IMF sends the routing information to the SMS-GMSC via the HLR or HSS, or directly sends the routing information to the SMS-GMSC, which may specifically depend on the network deployment condition and whether the signaling protocol is consistent or not.
As a preferred embodiment, the association identifier may associate the receiver information, the sender information, the routing information, or a combination thereof, for example, the receiver information may be a number or an International Mobile Station Identity (IMSI); the routing information may be information of a control network element of a network to which the receiving party accesses, for example, Mobile Switching Center (MSC) information, Serving GPRS Support Node (SGSN) information, and/or Mobility Management Entity (MME) information, and may of course also include receiving party information and sending party information.
Corresponding to the above method, this embodiment provides a routing information processing apparatus, which is located in an MTC-IWF and is used to implement the foregoing embodiment and preferred embodiments, which have already been described and are not described again. As used below, the term "module" may be a combination of software and/or hardware that implements a predetermined function.

Through the device, the MTC-IWF carries the association identifier when sending the message to the SMS-SC, so when the SMS-GMSC forwards the message from the SMS-SC, the association identifier cannot be identified, and effective routing information cannot be obtained, therefore, the association identifier needs to be sent to the MTC-IWF to inquire the routing information, and the 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-GMSC needs to use the association identifier to obtain the routing information again when the message is forwarded again after the message is failed to be forwarded, and the routing information is updated, the problem caused by using an error route to send the message in the related technology is solved, and the reliability of message sending is improved.
In the present embodiment, a message sending system is provided, and fig. 6 is a block diagram of a routing information processing system according to an embodiment of the present invention, and as shown in fig. 6, the system includes a routing information processing apparatus 30 (the routing information processing apparatus 30 in fig. 3 is taken as an example in fig. 6) located in an MTC-IWF as shown in any one of fig. 3 to 5, an SMS-SC40, an SMS-GMSC50, and an HLR or HSS 60.
This embodiment provides another routing information processing method, and fig. 7 is a flowchart of another routing information processing method according to an embodiment of the present invention, as shown in fig. 7, the method includes the following steps:
step S702, the short message service center (SMS-SC) fails to send a message, wherein the message sets routing information;
in step S704, the SMS-SC sets the above-mentioned routing information to be invalid for the message.
Through the above steps, when the SMS-SC is triggered to send the message again after failing to send the message with the routing information set, the routing information is set to be invalid for the message, so that when the SMS-GMSC sends the message, because the message does not have valid routing information, the SMS-GMSC queries the HLR or the HSS for the routing message, thereby updating the routing information, solving the problem caused by sending the message using a wrong route in the related art, and improving the reliability of message sending.
For example, when the message is from MTC-IWF, the above procedure may be: firstly, a short message service center (SMS-SC) receives a message sending request carrying routing information from a machine type communication interactive function (MTC-IWF); second, the SMS-SC fails to send a message with the routing information set, and the SMS-SC sets the routing information invalid for the message.
As a preferred embodiment, the routing information may include information of a control network element of a network to which the receiving party accesses, for example, Mobile Switching Center (MSC) information, Serving GPRS Support Node (SGSN) information, and Mobility Management Entity (MME) information.

step S1402: the MTC-IWF sends an inquiry routing message to the HLR or the HSS, wherein the inquiry routing message carries the Information of the receiving party, for example, the MTC-IWF sends a Subscriber Information Request message, which carries the number of the receiving party.
Step S1404: the HLR or HSS sends a routing information message to the MTC-IWF, for example, a SubscriberInformationResponse message is sent, which carries routing information.
Step S1406: the MTC-IWF assigns an association identifier C-ID, wherein the C-ID can be associated with information of a receiving party, routing information, information of a sending party and a combination of the C-ID and the routing information, and particularly, when the C-ID is associated with the information of the receiving party, the C-ID is a number or an identifier of the receiving party.
Step S1408: the MTC-IWF sends a message to the SMS-SC, carries the C-ID, and for the case that a plurality of MTC-IWFs exist, the associated identifier C-ID can also contain information of the MTC-IWF, for example, a Submit Trigger message can be sent.
Step S1410: the SMS-SC sends a message to the SMS-GMSC, e.g., an SMS-Delivery message may be sent, the message carrying the C-ID.
Step S1412: the SMS-GMSC sends an enquiry message to the HLR or HSS, e.g. a MAP SRI For SMrequest message may be sent, the message carrying the C-ID.
Step S1414: HLR or HSS forwards the inquiry message to MTC-IWF, carrying C-ID.
In step S1414, there may be another embodiment, that the SMS-GMSC may directly send a message to the MTC-IWF, carrying the C-ID.
The MTC-IWF sending the association identifier may not be the MTC-IWF receiving the association identifier, and a distribution mechanism, such as providing an MTC-IWF coordinator, needs to be deployed at this time, so that the MTC-IWF receiving the association identifier can obtain the association information from the MTC-IWF sending the association identifier, for example, obtain and request the MTC-IWF sending the C-ID through the MTC-IWF coordinator.
Step S1416: the MTC-IWF obtains routing information based on the C-ID, and may query the HLR or HSS for a route based on the receiver information (such as IMSI information) associated with the C-ID, or directly return the associated routing information when the C-ID is received for the first time and query the HLR or HSS for a route when it is subsequently received, for example.
Step S1418: the MTC-IWF sends routing information to the SMS-GMSC, For example, may send a MAP _ SRI _ For _ response message, which may pass through the HLR or HSS depending on the network deployment situation or whether 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 HSS, the SMS-GMSC forwards the message to the MSC or SGSN or MME according to the routing information, e.g. sends a MAP _ MT _ Forward _ smsreq message, the message carrying the recipient information, e.g. IMSI.
Step S1422: the MSC or SGSN or MME forwards the Message, e.g. sends a Transfer Message, to the recipient.
From the above description, it can be seen that the preferred embodiment achieves the following technical effects: by updating the routing information, the problem caused by using a wrong route to send the message in the related technology is solved, and the reliability of message sending is improved.

Step S1504: the HLR or HSS sends a routing information message to the MTC-IWF, for example, a SubscriberInformationResponse message is sent, which carries routing information.
Step S1506: and the MTC-IWF sends a message to a receiving party 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, where the message sets Routing information, for example, the obtained Routing information is carried in the message, or the SMS-SC provides the Routing information to the short message gateway mobile switching center SMS-GMSC, where the Routing information can be provided by carrying the obtained Routing information in the message, or can provide the Routing information to the SMS-GMSC before sending the message, for example, sending a Routing indication (Routing indication) signaling.
Step S1510: the SMS-GMSC has obtained the routing information and therefore no longer sends an inquiry routing message to the HLR or HSS, the SMS-GMSC forwards the message to the MSC or SGSN or MME according to the routing information, e.g. sends a MAP _ MT _ Forward _ smsreq message, the message carrying the recipient information, e.g. IMSI.
Step S1512: the message transmission fails, which may be due to some reason, such as insufficient memory or weak signal in the device.
Step S1514: when the terminal device is again available to receive the message, the SMS-SC receives a trigger, which may be from the HLR or HSS, and may again send the message to the recipient.
Step S1516: the SMS-SC sends a message to the SMS-GMSC that does not carry routing information.
Step S1518: the SMS-GMSC sends an inquiry routing message to the HLR or HSS, e.g., may send a MAP _ SRI _ For _ SM request message, carrying the recipient information.
Step S1520: the HLR or HSS returns routing information, e.g., a MAP _ SRI _ For _ SM response message may be sent, carrying the routing information.
Step S1522: the SMS-GMSC has obtained the routing information and therefore no longer sends an inquiry routing message to the HLR or HSS, the SMS-GMSC forwards the message to the MSC or SGSN or MME according to the routing information, e.g. sends a MAP _ MT _ Forward _ smsreq message, the message carrying the recipient information, e.g. IMSI.
Step S1524: the MSC or SGSN or MME forwards the Message, e.g. sends a Transfer Message, to the recipient.
