[0066] Figure 1 This is an optional flowchart of the message processing method provided in the embodiments of this application. Figure 1The method may include, but is not limited to, steps S101 to S105.

[0067] Step S101: The call session control function unit constructs a short message center query domain name based on the domain name of the received session invitation message.

[0068] In some embodiments, if querying the call session control function unit to obtain service call session control function unit information fails, then the call session control function unit constructs the short message center query domain name based on the domain name of the received session invitation message.

[0069] If the query call session control function unit fails to request location information, the query call session control function unit constructs a short message center query domain name based on the domain name of the received session invitation message.

[0070] Optionally, if the query call session control function unit detects that all links of the routing agent node are blocked, the query call session control function unit constructs a short message center query domain name based on the domain name of the received session invitation message.

[0071] Furthermore, the domain name is extracted from the received session invitation message by querying the call session control function unit, and the domain name is used to construct the short message center query domain name.

[0072] Understandably, if the query call session control unit cannot directly construct a domain name, a configuration file or dynamic DNS service can be used to assist in determining the query domain name.

[0073] In this embodiment, by querying the call session control function unit to construct the short message center query domain name based on the domain name of the received session invitation message, it is beneficial to correctly locate the short message center and improve the accuracy and efficiency of the query.

[0074] Step S102: The call session control function unit queries the domain name system based on the short message center query domain name to obtain the short message center address.

[0075] Specifically, a Domain Name System (DNS) query is a lookup of information from the Domain Name System.

[0076] In some embodiments, the call session control function unit is asked to perform a DNS query based on the short message center query domain name to obtain the short message center address.

[0077] Furthermore, a DNS caching mechanism can be implemented to reduce frequent queries.

[0078] Optionally, DNS load balancing can be used to improve system reliability and performance.

[0079] In this embodiment, by querying the call session control function unit to perform a domain name system query based on the short message center query domain name, the short message center address is obtained, which helps to obtain the correct short message center address and improve the system's response speed and accuracy.

[0080] Step S103: The session invitation message is forwarded to the short message center by querying the call session control function unit.

[0081] Specifically, the short message center is determined based on the short message center address.

[0082] In some embodiments, the Ma interface can be used to forward the session invitation message to the short message center.

[0083] Furthermore, a message queue mechanism is used to handle forwarding requests, improving the reliable delivery and processing of messages.

[0084] In this embodiment, by querying the call session control function unit to forward the session invitation message to the SMSC, it is beneficial for the session invitation message to be accurately delivered to the SMSC for subsequent processing.

[0085] Step S104: Obtain the service call session control function unit information through the short message center based on the session invitation message, add the service call session control function unit information to the session invitation message, and return the added session invitation message to the query call session control function unit.

[0086] Specifically, the service call session control function unit information includes the service call session control function unit hostname.

[0087] In some embodiments, the service call session control function unit information is obtained by querying the database based on the number in the session invitation message through the short message center.

[0088] Furthermore, routing information is added to the routing header field of the session invitation message. This routing information includes information about the query call session control function unit and information about the service call session control function unit. The query call session control function unit information includes the address of the query call session control function unit, and the service call session control function unit information includes the address of the service call session control function unit.

[0089] Optionally, a load balancing mechanism for the short message center can be implemented to handle a large number of session requests. Specifically, the load balancing mechanism can be implemented through hardware load balancers, software load balancers, clustering and replication, message queues, rate limiting, and degradation strategies.

[0090] In this embodiment, the service call session control function unit information is obtained by the short message center based on the session invitation message. The service call session control function unit information is added to the session invitation message, and the added session invitation message is returned to the query call session control function unit. This helps the call session control function unit obtain accurate service call session control function unit information and optimizes the management and control of call sessions.

[0091] Step S105: Based on the service call session control function unit information in the session invitation message, locate the call dialogue to the corresponding service call session control function unit by querying the call session control function unit.

[0092] Specifically, the service call session control function unit determines based on the service call session control function unit information.

[0093] In some embodiments, routing information for a session invitation message is obtained by querying the call session control function unit; information for querying the call session control function unit is removed by querying the call session control function unit; and the dialogue is directed to the service call session control function unit by querying the call session control function unit.

[0094] Optionally, the query call session control function unit implements dynamic load balancing and failover mechanisms to improve the system's reliability and fault tolerance.

[0095] In this embodiment, based on the service call session control function unit information in the session invitation message, the call dialogue is located to the corresponding service call session control function unit by querying the call session control function unit. This enables the service call session control function unit to query services, ensuring that the session request is accurately directed to the correct service call session control function unit. This helps improve the performance, continuity, and stability of the communication system, and enhances user experience and service quality.

[0096] Steps S101 to S105 as illustrated in this embodiment involve: The call session control function unit constructs a short message center query domain name based on the domain name of the received session invitation message, improving query accuracy and efficiency; the call session control function unit performs a domain name system query based on the short message center query domain name to obtain the short message center address; the call session control function unit forwards the session invitation message to the short message center; the short message center obtains the service call session control function unit information based on the session invitation message, adds the service call session control function unit information to the session invitation message, and returns the added session invitation message to the call session control function unit, facilitating call session location and processing; based on the service call session control function unit information in the session invitation message, the call session is located to the corresponding service call session control function unit through the call session control function unit query, thereby realizing the service call session control function unit query service, which helps improve the performance, continuity, and stability of the communication system, and enhances user experience and service quality.

[0097] Please see Figure 2 In some embodiments, step S102 may include, but is not limited to, steps S201 to S203:

[0098] Step S201: The call session control function unit was asked if the request for location information had failed.

[0099] In step S201 of some embodiments, a timeout period or number of retries is set.

[0100] Furthermore, when the call session control function unit requests location information, if the response time exceeds the timeout period, the request fails. If the number of failed requests exceeds the number of retries, the call session control function unit is considered to have failed to request location information.

[0101] In this embodiment, if the query call session control function unit fails to request location information, the method of this application can be used to request location information, which helps to improve the performance, continuity and stability of the communication system, thereby improving user experience and service quality.

[0102] Step S202: The call session control function unit detects that all links of the routing agent node are blocked.

[0103] In step S202 of some embodiments, the call session control function unit actively sends a probe packet (such as a ping packet) and waits for a response within a certain period of time.

[0104] Understandably, a timeout period can be set. If no response is received after the preset timeout period, it is assumed that there is a problem with the link of the routing agent node.

[0105] In this embodiment, if the query call session control function unit detects that all links of the routing agent node are blocked, the method of this application can be used to request location information, which helps to improve the performance, continuity and stability of the communication system, thereby improving user experience and service quality.

[0106] Step S203: The call session control function unit constructs a short message center query domain name based on the domain name of the received session invitation message.

[0107] Specifically, the short message center query domain name is a subdomain related to the short message center, used to indicate the location of the short message center.

[0108] In step S203 of some embodiments, the domain name in the session invitation message is extracted, and the short message center query domain name is constructed based on the extracted domain name.

[0109] In this embodiment, by querying the call session control function unit to construct the short message center query domain name based on the domain name of the received session invitation message, it is beneficial to correctly locate the short message center and improve the accuracy and efficiency of the query.

[0110] Please see Figure 3 In some embodiments, step S105 may include, but is not limited to, steps S301 to S303:

[0111] Step S301: Obtain the routing information of the session invitation message by querying the call session control function unit.

[0112] In step S301 of some embodiments, routing information of the session invitation message is obtained by querying the call session control function unit call interface.

[0113] In this embodiment, obtaining the routing information of the session invitation message by querying the call session control function unit helps the session locate the correct service call session control function unit, thereby improving the accuracy and timeliness of message transmission.

[0114] Step S302: Remove the query call session control function unit information by querying the query call session control function unit.

[0115] In step S302 of some embodiments, the query call session control function unit information is removed by querying the call session control function unit call interface.

[0116] In this embodiment, removing the query call session control function unit information by querying the call session control function unit helps reduce the system load and prevents the processing of invalid information.

[0117] Step S303: The dialogue is located to the service call session control function unit by querying the call session control function unit.

[0118] In step S303 of some embodiments, the call continues to be routed to the session control function unit by querying the call session control function unit based on the information of the service call session control function unit.

[0119] Optionally, the conversation can be redirected from the inquiry call session control function unit to the service call session control function unit via the session continuity function unit.

[0120] In this embodiment, by querying the call session control function unit, the dialogue is located to the service call session control function unit, so that the session request is accurately directed to the correct service call session control function unit. This helps to improve the performance, continuity and stability of the communication system, and improve the user experience and service quality.

[0121] Please see Figure 4 In some embodiments, the message processing method provided in this application further includes a user notification step, which may include, but is not limited to, steps S401 to S402:

[0122] Step S401: The session is located to the user equipment through the service call session control function unit.

[0123] In step S401 of some embodiments, the service call session control function unit verifies the identity of the called user equipment. Specifically, the service call session control function unit checks the registration information to confirm whether the called user equipment has registered in the network and whether its identity information is valid.

[0124] Furthermore, the Service Call Session Control Function Unit sends a session invitation message to the called user equipment via the P-CSCF. This session invitation message contains session parameters and other relevant information.

[0125] In this embodiment, the session is located to the user equipment through the service call session control function unit, which is conducive to the smooth progress of the session and maintains the stability and security of the network.

[0126] Step S402: Notify the user of a new session request via the user equipment.

[0127] In step S402 of some embodiments, the user equipment notifies the user of a new session request by ringing a sound or displaying an incoming call notification.

[0128] In this embodiment, notifying the user of a new session request via the user equipment facilitates the smooth progress of the session and helps improve the user experience and service quality.

[0129] Figure 5 This is an optional flowchart of the message processing method provided in the embodiments of this application. Figure 5 The methods may include, but are not limited to, the following steps.

[0130] Step 1: If the I CSCF detects a failed lir query or a complete blockage of the DRA link, disaster recovery is enabled.

[0131] Specifically, I CSCF stands for Query Call Session Control Function Unit, lir stands for Location Information Request, and DRA stands for Routing Agent Node Link.

[0132] It is understood that the method described in this application can be used as a disaster recovery solution when LIR queries fail or DRA links are completely blocked. Furthermore, enabling disaster recovery means applying the solution described in this application.

[0133] Step 2: The I CSCF constructs a short message center query domain name query DNS resolution to obtain the short message center address.

[0134] Specifically, DNS stands for Domain Name System.

[0135] In some embodiments, the I CSCF constructs a short message center query domain name based on the domain name of the received session invitation message, queries the DNS resolution based on the short message center query domain name to obtain the short message center address, and forwards the session invitation message to the short message center.

[0136] Step 3: The I CSCF obtains route information containing the called number service SSCCF information from the SMS center.

[0137] Specifically, SSCCF stands for Service Call Session Control Function Unit, and route information refers to routing information.

[0138] In some embodiments, the I CSCF obtains routing information from the short message center.

[0139] Step 4: The I CSCF forwards the call to the called party's SSCCF to complete the call setup.

[0140] In some embodiments, based on the service call session control function unit information in the session invitation message, the call dialogue is located to the corresponding service call session control function unit by querying the call session control function unit.

[0141] In this embodiment, when the HSS / UDM network element experiences a dual-node failure or the DRA link becomes congested or completely blocked, making it impossible to obtain the called number service SSCCF information in a timely manner, the registered number service SSCCF information stored in the SMS center is used as the home user service proxy, and the SIP protocol is used to replace the D IAMETER protocol to provide location information query services for the voice called service, thus maintaining the continuity of voice services.

[0142] For example, a business scenario diagram of HSS / UDM dual-machine failure or DRA failure is shown below. Figure 6 As shown in the diagram. The symbol 'x' indicates a communication failure, and light gray indicates that the communication could not proceed.

[0143] Figure 7 This is an optional flowchart illustrating the application of the message processing method provided in this application embodiment to HSS / UDM dual-machine failure or DRA failure. Figure 7 The methods may include, but are not limited to, the following steps.

[0144] Step 1: If the location information request does not respond, the ICSCF constructs a short message center query domain name based on the sip ur i domain name in the request-line to query the DNS and obtain the short message center address.

[0145] It is understandable that HSS / UDM dual-machine failure or DRA failure means that the location information request is not responded to, but HSS / UDM dual-machine failure or DRA failure does not affect the outgoing number.

[0146] In some embodiments, when the ICSCF network element detects a location information request failure, mainly manifested as a timeout with no response, or a complete blockage of the DRA link, making it unable to obtain the called number service SSCCF information, it constructs a short message center query domain name based on the sip ur i domain name in the received invite message request-line to query the DNS and obtain the short message center address to which the called number belongs. Specifically, taking sip: +8613300000000@tj.ims.mnc011.mcc460.3gppnetwork.org as an example, it constructs the short message center query domain name _sms._udp.tj.ims.mnc011.mcc460.3gppnetwork.org and queries the DNS to obtain the short message center address to which the called number belongs.

[0147] Step 2: The I CSCF forwards the invite message to the Short Message Center via the Ma interface. The Short Message Center needs to add an invite message processing function to obtain the SSCCF service information of the called number based on the called number in the message. In the invite message returned to the I CSCF, only two routing information entries are added to the route header field: the first layer is the I CSCF address, and the second layer is the SSCCF service address of the called number. The rest of the message remains unchanged in order to hide the Short Message Center topology and prevent it from participating in the subsequent call process.

[0148] Specifically, the invite message is a session invitation message.

[0149] Understandably, in an IMS network, due to the introduction of third-party registration processes for short messages, the short message center can obtain and store the service SSCCF information of all registered numbers, forming a database of registered number location information. For example, a standard registration flowchart is shown below. Figure 8 As shown.

[0150] In some embodiments, the ICSCF network element obtains the address of the Short Message Service Center (SSFC) to which the called number belongs, and forwards the invite message to the SSCCF via the Ma interface. The SSCCF adds an invite message processing function, acting as the home subscriber service agent. Based on the called number in the received invite message request-line, it queries the database to obtain the SSCCF hostname of the number. In the invite message returned to the ICSCF, only two routing information entries are added to the route header field: the first layer is the ICSCF information, and the second layer is the called number service SSCCF information. The rest of the message remains unchanged to hide the SSCCF topology and prevent it from participating in subsequent call processes.

[0151] Step 3: Based on the obtained routing information, the I CSCF removes its own address from the first layer and continues to route the call to the SSCCF where the called number is located according to the address of the second layer service SSCCF, thus completing the subsequent call process.

[0152] In some embodiments, the I CSCF removes its own information at the first layer based on the routing information in the invite message returned by the SMS center, and continues to route the call to the SSCCF where the called number is located according to the SSCCF information at the second layer service, thus completing the subsequent call process.

[0153] In this embodiment, the Short Message Service (SMS) center acts as the Home Subscriber Service (NSS) agent, the SIP protocol replaces the DIAMETER protocol, the SMS center adds the ability to process incoming messages, and receives and processes call requests forwarded by the ICSCF network element when the diameter fails, extracts and returns SCSCF routing information, and provides a disaster recovery method for providing location information query services for voice services.

[0154] It is understandable that this application uses existing resources of existing systems in the current network, utilizes the existing short message center as the home user service agent, and adds the invite message processing capability of the short message center to provide location information query service for voice services. Compared with existing technologies, it has higher reliability, stronger real-time performance, simpler logic, and does not require additional system overhead and signaling consumption.

[0155] Furthermore, this application can effectively alleviate voice service disruptions caused by LIR query failures due to HSS / UDM dual-machine failures or DRA failures, maintaining the continuity of voice services. Simultaneously, based on the existing IMS network topology, when signaling storms occur, the bottleneck often lies in the DRA / HSS / UDM and other diameter network elements. The processing capacity of the DRA / HSS / UDM network elements determines the maximum processing capacity of the IMS network during signaling storms. This application can redirect HSS query requests for voice calls to the Home Subscriber Service (NAS) agent in extreme failure scenarios such as signaling storms, separating IMS registration requests from call requests, effectively alleviating the pressure on the DRA / HSS / UDM network elements, and improving the overall processing capacity of the IMS network.

[0160] A new module 904 is added, which is used to obtain the service call session control function unit information through the short message center based on the session invitation message, add the service call session control function unit information to the session invitation message, and return the added session invitation message to the query call session control function unit.
