The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
For the existing problems, in the embodiment of the present application, when the short message gateway finds that the S-CSCF device registered by the 5G SA user is completely unavailable, the MT short message of the 5G SA user sent to the S-CSCF device is forwarded to an inquiry-Call Session Control Function (I-CSCF) device corresponding to the 5G SA user, and the I-CSCF device selects and delivers the S-CSCF device again, thereby ensuring the real-time property of the MT short message of the 5G SA user.
For ease of understanding, first, a brief description is made of an application scenario related to the embodiments of the present application.
Fig. 1 is an architecture diagram of a short message processing system according to an embodiment of the present application. As shown in fig. 1, the short message processing system includes a short message center, a short message gateway, and an IMS. The IMS core Function entity includes a Call Session Control Function (CSCF) device (network element) and a Home Subscriber Server (HSS). Furthermore, the CSCF device specifically includes an S-CSCF device and an I-CSCF device, wherein the S-CSCF device is configured to deliver the MT short message forwarded by the short message gateway, and the I-CSCF device is configured to receive the MT short message forwarded by the short message gateway and forward the MT short message to an available S-CSCF device queried from the HSS for delivery. Specifically, the S-CSCF device may include Sub>A S-CSCF-Sub>A device for registering Sub>A target user for receiving an MT short message, and other S-CSCF-B devices, S-CSCF-C devices, etc. having the same function.
It should be noted that the S-CSCF-B device and the S-CSCF-C device corresponding to the architecture diagram of the short message processing system provided in the embodiment of the present application are other S-CSCF-C devices registered by non-target users. It can be understood that the number of S-CSCF devices is not limited in the embodiments of the present application.
It should be noted that the short message processing system provided in the embodiment of the present application is suitable for processing an MT short message of a 5G SA user. Specifically, in the 5G SA network, the short message gateway may include a Voice over Long-Term Evolution (VoLTE) short message gateway and a Voice over New Radio (VoNR) short message gateway, where a user registered in the VoLTE short message gateway is referred to as a VoLTE user, a user registered in the VoNR short message gateway is referred to as a VoNR user, and a type of the short message gateway is not limited in the embodiment of the present application.
Specifically, the short message processing flow may be: after receiving an MT (mobile terminal) short message of a target user registered to a short message gateway, a short message center acquires an IP (Internet protocol) address of the target user from an IMS (IP multimedia subsystem), and sends the MT short message to the short message gateway according to the IP address, further the short message gateway determines whether S-CSCF (session control function call session control function) equipment registered by the target user is in a fault state, when the S-CSCF equipment registered by the target user is in the fault state, the short message gateway forwards the MT short message to I-CSCF (inter-call session control function) equipment, and the I-CSCF equipment further inquires available S-CSCF equipment from an HSS (home subscriber server) and forwards the MT short message to the inquired available S-CSCF equipment for delivery; and when the S-CSCF equipment registered by the target user is not in a fault state, the short message gateway directly forwards the MT short message to the S-CSCF equipment for delivery.
Taking the above-mentioned architecture diagram of the short message processing system as an example, the following describes the short message processing method provided in the embodiments of the present application in detail with reference to specific embodiments.
Fig. 2 is a flowchart of a short message processing method according to an embodiment of the present application. As shown in fig. 2, the short message processing method includes the following steps:
s201, receiving MT short messages which are sent by the short message center based on the IP address of the target user and are oriented to the target user.
Alternatively, the target user may be a 5G SA user.
Optionally, the IP address of the target user may be an IP address of the target user when performing IMS registration, and specifically, the IP address may be used to match a corresponding short message gateway, and may also be used to match S-CSCF equipment registered by the target user. For example, when the short message gateway is a VoLTE short message gateway, it may be determined whether the target user is a corresponding VoLTE user according to the IP address, that is, only the VoLTE user may perform the MT short message processing on the target user through the VoLTE short message gateway.
Optionally, the MT short message may be a short message received by the terminal, that is, a short message sent to the terminal device through the system. For example, the terminal device may be a mobile phone, a wearable device, a tablet computer, and the like, which may be used to receive a short message.
S202, whether the first S-CSCF equipment registered by the target user is in a failure state is determined.
Step S203 is executed in response to the first S-CSCF device being in a failure state, and step S204 is executed in response to the first S-CSCF device not being in a failure state.
Optionally, the first S-CSCF device with which the target user is registered may be identified by a hostname of the first S-CSCF device.
The function of the S-CSCF device is described herein, where the S-CSCF device is configured to perform session control and a registration request for a User Equipment (UE), and when the UE is in a session, the S-CSCF device is configured to process a session state in a network.
Optionally, the reason that the first S-CSCF device is in the failure state may be that the first S-CSCF device itself fails, or an IP address under a domain name corresponding to the first S-CSCF device is unavailable, and/or a port under the domain name is unavailable. For example, the domain name corresponding to the first S-CSCF device may be a host name of the first S-CSCF device, and the IP address may be a transport protocol.
It should be noted that, when the first S-CSCF device is in the failure state, if the first S-CSCF device continues to deliver the MT short message, the MT short message may be delivered only after the first S-CSCF device re-registers, but the period for re-registering the first S-CSCF device is long, so that the MT short message cannot be delivered in a short time. The period for re-registration of the first S-CSCF device may be, for example, 50 minutes.
And S203, forwarding the MT short message to an I-CSCF device, wherein the I-CSCF device is used for sending the MT short message to an available second S-CSCF device for delivery.
The function of the I-CSCF device is explained first. The I-CSCF equipment is used for inquiring the S-CSCF equipment in the HSS, selecting the S-CSCF equipment from the HSS and forwarding the message received by the I-CSCF equipment from the short message gateway to the S-CSCF equipment selected from the HSS.
Optionally, the I-CSCF device sequentially queries available S-CSCF devices from the HSS, and uses the queried first available S-CSCF device as the second S-CSCF device. In particular, the target user does not need to register the second S-CSCF device.
S204, the MT short message is forwarded to the first S-CSCF equipment for delivery.
It can be understood that, when the first S-CSCF device itself is not in a fault and an available IP address and port exist in the domain name corresponding to the first S-CSCF device, the first S-CSCF device is not in a fault state, and may receive an MT short message sent from the short message gateway and deliver the MT short message.
In the embodiment of the application, after receiving an MT short message which is sent by a short message center based on an IP address of a target user and faces the target user, whether a first S-CSCF device registered by the target user is in a fault state is determined firstly, when the first S-CSCF device is in the fault state, the MT short message is forwarded to an I-CSCF device, and the MT short message is sent to an available second S-CSCF device through the I-CSCF device to be delivered, so that the target user can deliver the MT short message without re-registering the first S-CSCF device, and when the first S-CSCF device is not in the fault state, the MT short message is forwarded to the first S-CSCF device to be delivered, so that the time delay of delivery of the MT short message is shortened, and the real-time performance of the MT short message is guaranteed.
Optionally, on the basis of the foregoing embodiment, before determining whether the first S-CSCF device registered by the target user is in the failure state, the method may further include the steps of: and determining the target user as the 5G SA user according to the information positioned in the head domain of the access position information in the user registration information of the target user. Specifically, the access location information header field is used to indicate whether the short message gateway registered by the target user is consistent with the short message gateway used in the short message processing system. Illustratively, when the short message gateway used in the short message processing system is a VoLTE short message gateway, the corresponding Access location information header of the target user may be a P-Access-Network-Info header, indicating that the target user is a VoLTE user.
For example, the information located in the header field of the access location information may be a third Generation Partnership Project-NR-Time division Duplex mode (3 rd Generation Partnership Project-New Radio-Time-division Duplex mode, 3 GPP-NR-FDD) or a third Generation Partnership Project-NR-Frequency division Duplex mode (3 rd Generation Partnership Project-New Radio-Frequency-division Duplex mode, 3 GPP-NR-FDD), and a user carrying a 3GPP-NR-FDD or 3GPP-NR-TDD tag is determined to be a 5G SA user.
It can be understood that the short message processing method provided in the embodiment of the present application is to process an MT short message of a 5G SA user, and therefore, before determining whether a first S-CSCF device registered by a target user is in a fault state, a tag is marked on the user to identify whether the user is a 5G SA user.
It should be noted that, in the short message processing method provided in this embodiment of the present application, in order to avoid a situation that the first S-CSCF device is in a failure state when a single IP address corresponding to the first S-CSCF device is unavailable, the short message gateway delivers the MT short message through the domain name of the first S-CSCF device. Optionally, the MT short message is forwarded to the S-CSCF device for delivery according to the domain name of the first S-CSCF device. For example, the short message gateway MT short message delivery mode may be delivered from the pre-recorded IP address of the first S-CSCF device, instead of using the domain name of the first S-CSCF device. It can be understood that, when the domain name is used to deliver the MT short message, other IP addresses of the first S-CSCF device may be selected according to the domain name to deliver the MT short message when the pre-recorded IP address of the first S-CSCF device is unavailable, so as to enhance the availability of the first S-CSCF device.
In addition to the above embodiments, step S202 in the embodiments of the present application will be described in detail below with reference to fig. 3.
Fig. 3 is a flowchart of a short message processing method according to another embodiment of the present application. As shown in fig. 3, specifically, determining whether the first S-CSCF device registered by the target user is in the failure state may further include the following steps:
s301, reading a pre-detection result of the first S-CSCF device, wherein the pre-detection result is obtained by pre-detecting the IP address and the port of the first S-CSCF device under the domain name.
Wherein, in response to the pre-detection result indicating that none of the IP addresses under the domain name is available and/or none of the ports under the domain name is available, executing step S302; in response to the preview result being that at least one IP address or at least one port under the domain name is available, step S303 is performed.
Optionally, a specific implementation manner of performing pre-detection on the IP address and the port of the first S-CSCF device under the domain name may be: and performing periodical pre-detection on the first S-CSCF equipment by adopting Options detection to obtain a pre-detection result. For example, the pre-check period may be 30 minutes, or 1 hour.
S302, in response to the pre-detection result that the IP address under the domain name is unavailable and/or the port under the domain name is unavailable, determining that the first S-CSCF equipment is in a failure state.
And S303, determining that the first S-CSCF equipment is not in a failure state in response to the pre-detection result that at least one IP address or at least one port under the domain name is available.
In the embodiment of the application, the first S-CSCF equipment is determined to be in a fault state by reading the pre-detection result of the first S-CSCF equipment and responding to the fact that the pre-detection result indicates that the IP address under the domain name of the first S-CSCF equipment is unavailable and/or the port under the domain name of the first S-CSCF equipment is unavailable; and in response to the pre-detection result that at least one IP address or at least one port under the domain name of the first S-CSCF equipment is available, determining that the first S-CSCF equipment is not in a fault state, and periodically pre-detecting the first S-CSCF equipment so as to acquire information whether the first S-CSCF equipment is in the fault state in real time and ensure the real-time property of the MT short message.
On the basis of the foregoing embodiment, optionally, forwarding the MT short message to the I-CSCF device may specifically include the following steps: acquiring address information of the I-CSCF equipment from a domain name system based on the resource record type; and forwarding the MT short message to the I-CSCF equipment according to the address information.
Alternatively, the resource record types may be a Name Authority Pointer (NAPTR) record, a Service (SRV) record, and a host record, such as an Address record (a record). Specifically, the NAPTR record is used to map a telephone number to a Domain Name System (DNS) server, and the SRV record is used to define the location of the DNS server that provides a specific service; the a record is an important record for name resolution that maps a particular host name (or domain name) to the IP address of the corresponding host.
Alternatively, the domain name system may be DNS or ENUM. Specifically, the DNS is a distributed database that maps domain names and IP addresses to each other, facilitating access to the internet. ENUM is a protocol defined by The telephone number Mapping working group (e.g., 164number UR I Mapping, ENUM for short) of The Internet Engineering Task Force (IETF), and is used to search various information such as an email, an IP telephone number, a unified message, an IP fax, and a personal web page of a Registrant (registry) according to a telephone number.
In one possible implementation, the address information of the I-CSCF device is queried from the ENUM or DNS system via a NAPTR record or an SRV record or an a record.
Fig. 4 is a device interaction diagram of a short message processing flow provided in the embodiment of the present application. As shown in fig. 4, when the short message gateway reads that the pre-detection result of the first S-CSCF device is in the failure state, the address information of the I-CSCF device is queried from the ENUM or DNS system based on the NAPTR record or the SRV record or the a record, the ENUM or DNS system returns the queried address information of the I-CSCF device to the short message gateway, the short message gateway forwards the MT short message to the I-CSCF device based on the address information, and the I-CSCF device forwards the MT short message to the available second S-CSCF device queried from the HSS for delivery. And after the short message gateway, the I-CSCF equipment and the second S-CSCF equipment finish the forwarding or delivery of the MT short message, 200OK responses are returned to indicate that the corresponding MT short message is successfully forwarded or delivered.
