Sometimes, signaling storms occur in the network. In a signaling storm scenario, a large number of users concurrently register or call, so that a large number of Diameter messages are collectively sent to a Home Subscriber Server (HSS) of an IP Multimedia Subsystem (IMS), which causes an overload of the HSS device and causes adverse effects.

Detailed Description
Features and exemplary embodiments of various aspects of the present invention will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention. The present invention is in no way limited to any specific configuration and algorithm set forth below, but rather covers any modification, replacement or improvement of elements, components or algorithms without departing from the spirit of the invention. In the drawings and the following description, well-known structures and techniques are not shown in order to avoid unnecessarily obscuring the present invention.
The embodiment of the invention provides a communication service processing method and a system, which can be applied to a scene that a signaling storm occurs in the direction of a Home Subscriber Server (HSS) in a network. Fig. 1 is a schematic diagram of a network topology of a Voice over Long-Term Evolution (VoLTE) Voice bearer in an embodiment of the present invention. AS shown in fig. 1, the VOLTE network includes a calling terminal, a Call Session Control Function (CSCF) unit, an Application Server (AS), a Diameter Routing Agent (DRA), a network protocol Multimedia Subsystem Home Subscriber Server (IP Multimedia Subsystem-Home Subscriber Server, IMS-HSS), a Media Gateway Control Function (MGCF) unit, a Mobile Switching Center (MSC), a Session Border Controller (SBC), a Home Location Register (Home Location Register, HLR), a called terminal, and the like.
The HSS may be a home subscriber server (IP Multimedia Subsystem-HSS) under the network protocol Multimedia Subsystem. The CSCF units may be specifically divided into a calling CSCF unit and a called CSCF unit. The ASs may be divided into a calling AS and a called AS. The MSCs can be divided into a calling MSC and a called MSC. The CSCF elements may be divided into Proxy-CSCF (P-CSCF) elements, Interrogating-CSCF (I-CSCF) elements and Serving-CSCF (S-CSCF). Wherein the I-CSCF elements and the S-CSCF elements may be integrated together, such as the calling I/S-CSCF and the called I/S-CSCF in fig. 1. The P-CSCF elements and SBCs may be integrated together, such as the calling pcsccf/SBC and the called pcsccf/SBC in figure 1. The HSS and HLR may be integrated together, as in the called HSS/HLR of fig. 1.
Fig. 2 is a communication service processing method applied to a service unit according to an embodiment of the present invention. As shown in fig. 2, the communication service processing method may include step S101 and step S102.
In step S101, the service element receives a Diameter protocol error code response message.
Among them, the Diameter (i.e., protocol cluster) protocol is an authentication, authorization, and auditing protocol used in a network. The Diameter protocol error code response message is used for representing signaling storm occurring in the HSS direction, and is a message under the Diameter protocol. The HSS direction may specifically be the IMS-HSS direction in fig. 1, i.e. the direction pointing towards the IMS-HSS. And a signaling storm occurs in the HSS direction, which indicates that the signaling quantity of the HSS direction exceeds the range of the normal signaling quantity.
The DRA is provided with a flow control strategy, for example, a normal signaling rate threshold range is set for each IMS-HSS direction, and if the signaling rate of the IMS-HSS direction exceeds the normal signaling rate threshold range, a signaling storm occurs in the IMS-HSS direction. The signaling may be specifically various messages, etc., and is not limited herein. If signaling storm occurs in IMS-HSS direction, DRA intercepts signaling and sends Diameter protocol error code response message to service unit. The priority of the signaling can be set, and the signaling with low priority can be intercepted preferentially.
For example, the upper limit of the normal signaling rate threshold range of the DRA for sending the IMS-HSS direction is 1000MPS (megabits per second), and in order to preferentially ensure that the call service of the registered user is normal, the registration message with low priority may be preferentially intercepted. The User Authorization Request (UAR) message is a message type necessary in the registration process, and the UAR message only appears in the registration process and is a message type with the largest amount in the registration process. The priority of the UAR message may be set to a low level. An instant Location update Request (LIR) message appears only during a call, and the priority of the LIR message may be set to a high level. The priority of the remaining messages may be set to a medium level. And when the signaling rate exceeds the range of the normal signaling rate threshold, intercepting the UAR message preferentially and sending a Diameter protocol error code response message corresponding to the UAR message. If the message rate still exceeds the normal signaling rate threshold range after the messages with the low-level priority and the messages with the medium-level priority are all intercepted, intercepting the LIR messages and sending Diameter protocol error code response messages corresponding to the LIR messages.
In some examples, the service element may specifically be a CSCF element and/or an AS. If the calling terminal is in the registration process, the service unit may specifically include a calling I/S-CSCF unit and/or a calling AS. If the calling terminal is in the process of calling, the service unit can comprise a called I/S-CSCF unit and/or a called AS.
In step S102, the service unit generates and sends a Session Initiation Protocol (SIP) error code response message to the calling terminal according to the Diameter error code response message.
The SIP error code response message is used to instruct the calling terminal to initiate a registration request after a delay or to call the called terminal through a Circuit Switching (CS) network. The SIP error code response message corresponds to a Diameter protocol error code response message. The SIP error code response message corresponding to the Diameter protocol error code response message sent by the calling terminal in the registration process is different from the SIP error code response message corresponding to the Diameter protocol error code response message sent by the calling terminal in the calling process. Specifically, if the calling terminal is in the registration process, the corresponding SIP error code response message is used to indicate that the calling terminal initiates the registration request after a delay. And if the calling terminal is in the calling process, the corresponding SIP error code response message is used for indicating the calling terminal to call the called terminal through the CS network.
It should be noted that the Diameter protocol error code response message may be configured by DRA, that is, the content of a specific field in the Diameter protocol error code response message may be configured by DRA. The SIP error code response message may be configured by the service unit, i.e. the content of specific fields in the SIP error code response message may be configured by the service unit.
In the embodiment of the invention, the service unit receives the Diameter protocol error code response message, triggers and generates the SIP error code response message and sends the SIP error code response message to the calling terminal. The SIP error code response message is used to indicate that the calling terminal initiates a registration request after a delay or calls the called terminal through the CS network. Under the condition of signaling storm, the calling terminal can be indicated to take corresponding measures through the SIP error code response message, the signaling load of the HSS is lightened or the calling service is recovered, and therefore the adverse effect of the signaling storm on service processing is reduced.
The Diameter protocol error code response message includes an error code, and the SIP error code response message includes an error code. The error code in the Diameter protocol error code response message corresponds to the error code in the SIP error code response message.
In some examples, the SIP error code response message includes the first error code and registration interval duration information. The first error code is configured by the service unit and represents that a signaling storm occurs in the HSS direction during the registration process. For example, the error code in the Diameter protocol error code response message is 4888 error code, and indicates that a signaling storm occurs to the HSS during registration. Correspondingly, the first error code in the SIP error code response message may be 404 error codes. The error code in the Diameter error code response message and the first error code in the SIP error code response message may be configured, but are not limited herein.
The registration interval duration information represents the registration interval duration, and the calling terminal can initiate a registration request message according to the registration interval duration. Specifically, the calling terminal may initiate the registration request message after the registration interval duration.
For example, the upper limit of the normal signaling rate threshold range is 1000 MPS. The signaling rate for the IMS-HSS direction reaches 1200MPS, where the UAR message rate reaches 600MPS, and the remaining message rate reaches 600 MPS. The DRA randomly intercepts the UAR message of the 200MPS and sends a Diameter protocol error code response message including a 4888 error code. The rest of the messages are not intercepted. After receiving the Diameter error code response message including the 4888 error code sent by the DRA, the CSCF unit and/or the AS sends an SIP error code response message including 404 error code to the calling terminal in the registration procedure, where the SIP error code response message further includes registration interval duration information retry-after, and the registration interval duration indicated by the registration interval duration information is 30 minutes, for example. And after receiving the SIP error code response message, the calling terminal initiates a registration request at an interval of 30 minutes according to the registration interval duration indicated by the registration interval duration information. By adopting the communication service processing method in the embodiment of the invention, the registration service of the calling terminal is registered according to the registration interval duration interval indicated by the registration interval duration information, so that the sending rate of the registration request is reduced, namely the signaling rate in the direction of the HSS is reduced, thereby reducing the load of network equipment such as the HSS and ensuring that the related information in the calling process is not intercepted.
In other examples, the SIP error code response message includes a second error code. The second error code is configured by the service unit and represents that a signaling storm occurs in the direction of the HSS during the calling process. For example, the error code in the Diameter protocol error code response message is 4888 error code, and indicates signaling storm occurs in the HSS direction during the call. Correspondingly, the second error code in the SIP error code response message may be 500 error codes. The error code in the Diameter protocol error code response message and the second error code in the SIP error code response message may be configured, but are not limited herein.
For example, the upper limit of the normal signaling rate threshold range is 1000 MPS. The signaling rate in the IMS-HSS direction reaches 3000MPS, where UAR message rate reaches 1500MPS, call message rate reaches 1200MPS, and the rest reaches 300 MPS. The DRA intercepts all UAR messages. Since the call message rate 1200MPS still exceeds the upper limit 1000MPS of the normal signaling rate threshold range, some call messages will also be intercepted by the DRA. After receiving the Diameter error code response message including the 4888 error code sent by the DRA, the CSCF unit and/or AS sends a SIP error code response message including 404 error code and registration interval duration information to the calling terminal in the registration procedure. In addition, in the call flow, the CSCF unit and/or AS sends a SIP error code response message including 500 error codes to the calling terminal. After receiving the SIP error code response message including the 500 error codes, the calling terminal continues to initiate a call through the CS network, thereby ensuring that a call service between the calling terminal and the called terminal can be performed normally.
Fig. 3 is a flowchart of a communication service processing method for a terminal according to another embodiment of the present invention. As shown in fig. 3, the communication service processing method may include step S201 and step S202.
In step S201, the calling terminal receives the SIP error code response message.
The SIP error code response message is used for indicating the calling terminal to initiate a registration request after a delay or calling the called terminal through a CS network.
In step S202, the calling terminal initiates a registration request or calls the called terminal through the circuit-switched CS network after a delay according to the SIP error code response message.
If the calling terminal is in the registration process, the calling terminal initiates a registration request after a delay according to the SIP error code response message. If the calling terminal is in the calling process, the calling terminal calls the called terminal through the CS network according to the SIP error code response message.
In the embodiment of the invention, the calling terminal can perform corresponding processing according to the received SIP error code response message, namely, the registration request is initiated after delay or the called terminal is called through the CS network, the signaling load of the HSS is lightened or the calling service is recovered, thereby reducing the adverse effect of the signaling storm on the service processing.
In some examples, the SIP error code response message includes the first error code and registration interval duration information. The first error code represents that a signaling storm occurs in the direction of a Home Subscriber Server (HSS) in the registration process. If the SIP error code response message comprises the first error code, the calling terminal initiates a registration request after a delay.
The delaying initiation of the registration request by the calling terminal in step S202 in the foregoing embodiment may specifically be implemented as: and the calling terminal initiates a registration request according to the interval duration indicated by the registration interval duration information. Specifically, the calling terminal may initiate the registration request after the registration interval duration indicated by the registration interval duration information, or the calling terminal may initiate the registration request according to the registration interval duration indicated by the registration interval duration information. The registration interval duration may be set according to a specific work scenario and a work requirement, and is not limited herein. For example, the duration of the registration interval may be 30 minutes, and the calling terminal may initiate the registration request after 30 minutes, or the calling terminal may initiate the registration request at a periodic interval of 30 minutes.
The related information of the first error code can be referred to the related description in the above embodiments, and is not described herein again.
In further embodiments, the SIP error code response message includes a second error code. The second error code represents that a signaling storm occurs in the direction of the Home Subscriber Server (HSS) in the calling process. If the SIP error code response message comprises the second error code, the calling terminal calls the called terminal through the CS network. Thereby resuming call traffic.
The related information of the second error code can be referred to the related description in the above embodiments, and is not described herein again.
In the above embodiment, the calling terminal calls the called terminal through the CS network may be implemented in the following two manners, but is not limited thereto:
the first mode is as follows: if the calling terminal is in a Voice over Long-Term Evolution (VoLTE) network, the calling terminal falls back to the CS network, and calls the called terminal through the CS network.
The second mode is as follows: if the calling terminal is in the CS network, the calling terminal sends a data deletion instruction to the HSS/HLR of the called terminal, and calls the called terminal through the CS network. And the data deleting instruction is used for indicating to delete the called anchor template data of the called terminal. If the called anchoring template data of the called terminal is deleted, the called terminal calling the VoLTE network under the CS network does not enter the IMS domain through the MGCF any more to inquire the called terminal, and the call intercepted in the VoLTE network can be ensured to be normally connected in the CS network.
In some examples, if the calling terminal is in the CS network and the signaling rate in the HSS direction returns to within the normal signaling rate threshold range, the calling terminal sends a data addition instruction to the home subscriber server/home location register HSS/HLR of the called terminal. The data adding instruction is used for indicating the addition of called anchor template data of the called terminal. The called anchoring template data of the called terminal is added, so that the calling terminal can be prompted to dial the called terminal using the VoLTE network under the CS network and enter the IMS domain through the MGCF to inquire the called terminal, and the IMS-HSS equipment can normally undertake services.
