Sometimes, signaling storms occur in the network. In the signaling storm scenario, a large number of users register or call concurrently, so that a large number of Diameter messages are intensively sent to a home subscriber server (Home Subscriber Server, HSS) of a network protocol multimedia subsystem (IP Multimedia Subsystem, IMS), which causes overload of HSS equipment and incapability of normally processing services for a long time, thereby causing adverse effects.

Detailed Description
Features and exemplary embodiments of various aspects of the invention are described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the 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 invention by showing examples of the invention. The present invention is in no way limited to any particular configuration and algorithm set forth below, but rather covers any modification, substitution, and improvement of elements, components, and algorithms without departing from the spirit of the invention. In the drawings and the following description, well-known structures and techniques have not been 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 signaling storm occurs in the direction of a home subscriber server (Home Subscriber Server, HSS) in a network. Fig. 1 is a schematic diagram of a network topology of a Long Term Evolution Voice-over-terminal Evolution (VoLTE) in an embodiment of the present invention. AS shown in fig. 1, the VOLTE network comprises a calling terminal, a call session control function (Call Session Control Function, CSCF) unit, an application server (Application Server, AS), a routing agent node (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 (Media Gateway Control Function, MGCF) unit, a mobile switching center (Mobile Switching Center, MSC), a session border controller (Session Border Controller, SBC), a home location register (Home Location Register, HLR), a called terminal, etc.
The HSS may specifically be a home subscriber server (IP Multimedia Subsystem-HSS, IMS-HSS) under the network protocol multimedia subsystem. The CSCF elements may be specifically divided into a calling CSCF element and a called CSCF element. The AS may be divided into a calling AS and a called AS. The MSC can be divided into a calling MSC and a called MSC. CSCF elements can be divided into Proxy-CSCF (P-CSCF) elements, query-CSCF (I-CSCF) elements and Serving-CSCF elements. Wherein the I-CSCF element and the S-CSCF element may be integrated, such as the calling I/S-CSCF and the called I/S-CSCF in fig. 1. The P-CSCF element may be integrated with the SBC, such as the calling PCSCF/SBC and the called PCSCF/SBC in fig. 1. The HSS and HLR may be integrated together as the called HSS/HLR in fig. 1.
Fig. 2 is a schematic diagram of 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 unit receives a Diameter protocol error code response message.
Where Diameter (i.e., protocol cluster) protocol is one of the authentication, authorization, and auditing protocols used in a network. The Diameter protocol error code response message is used for representing signaling storm in the HSS direction, and is a message under the Diameter protocol. The HSS-direction may in particular be the IMS-HSS-direction in fig. 1, i.e. the direction towards the IMS-HSS. Signaling storm occurs in the HSS direction, which means that the number of signaling in the HSS direction exceeds the normal number of signaling range.
The DRA is provided with a flow control policy, for example, a normal signaling rate threshold range is set for each IMS-HSS direction, and if the signaling rate in the IMS-HSS direction exceeds the normal signaling rate threshold range, a signaling storm is considered to occur in the IMS-HSS direction. The signaling may be, but is not limited to, various messages, etc. If a signaling storm occurs in the IMS-HSS direction, the DRA intercepts the signaling and sends a Diameter protocol error code response message to the service unit. The priority of the signaling can also be set, and signaling with low priority is intercepted preferentially.
For example, the upper limit of the normal signaling rate threshold range of the DRA for transmitting the IMS-HSS is 1000MPS (mega per second), so as to ensure the call service of the registered user is normal, and intercept the registration message with low priority. While the user authorization request (User Authorization Request, UAR) message is a message type that is necessary in the registration process, the UAR message only occurs in the registration process and is the message type that is the largest in the registration process. The priority of UAR messages may be set to a low level. The instant location request (Location Immediate Request, LIR) message only occurs during the call, and the priority of the LIR message may be set to a high ranking. The priority of the remaining messages may be set to a medium level. When the signaling rate exceeds the normal signaling rate threshold range, the UAR message is intercepted preferentially and a Diameter protocol error code response message corresponding to the UAR message is sent. If the message rate is still beyond the normal signaling rate threshold range after the low-level priority message and the medium-level priority message are all intercepted, intercepting the LIR message and sending a Diameter protocol error code response message corresponding to the LIR message.
In some examples, the service element may be in particular 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 call process, the service unit may include a called I/S-CSCF unit and/or a called AS.
In step S102, the service unit generates and sends a session initiation protocol (Session Initiation Protocol, SIP) error code response message to the calling terminal according to the Diameter protocol error code response message.
The SIP error code response message is used to instruct the calling terminal to initiate a registration request or call the called terminal through a Circuit Switch (CS) network after delay. 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 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 error code response message sent by the calling terminal in the call process. Specifically, if the calling terminal is in the registration process, the corresponding SIP error code response message is used to instruct the calling terminal to initiate the registration request after delay. 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 the DRA, that is, the content of a specific field in the Diameter protocol error code response message may be configured by the 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 the generation of 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 instruct the calling terminal to initiate a registration request after delay or call the called terminal through the CS network. Under the condition of signaling storm, the calling terminal can be instructed to make corresponding measures through the SIP error code response message, so that the signaling load of the HSS is lightened or the call service is restored, and 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 a first error code and registration interval duration information. The first error code is configured by the service unit and characterizes signaling storm in the HSS direction in the registration process. For example, the error code in the Diameter protocol error code response message is 4888 error code, and indicates that signaling storm occurs in the HSS direction in the registration process. Correspondingly, the first error code in the SIP error code response message may be 404 error code. Wherein, the error code in the Diameter protocol error code response message and the first error code in the SIP error code response message are configurable, which is not limited herein.
The registration interval duration information characterizes 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 1000MPS. The signaling rate in the IMS-HSS direction reaches 1200MPS, where the UAR message rate reaches 600MPS and the rest reaches 600MPS. The DRA intercepts the UAR message of 200MPS randomly and sends a Diameter protocol error code response message that includes a 4888 error code. The rest of the message is not intercepted. After receiving the Diameter error code response message including 4888 error code sent by the DRA, the CSCF element and/or the AS sends a SIP error code response message including 404 error codes to the calling terminal in the registration flow, 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. And after receiving the SIP error code response message, the calling terminal initiates a registration request according to the registration interval duration of 30 minutes 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 of the HSS direction is reduced, thereby reducing the load of network equipment such as the HSS and ensuring that the related information of 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 characterizes signaling storm in HSS direction during calling. For example, the error code in the Diameter protocol error code response message is 4888 error code, and indicates that a signaling storm occurs in the HSS direction during the call. Correspondingly, the second error code in the SIP error code response message may be a 500 error code. Wherein the error code in the Diameter protocol error code response message and the second error code in the SIP error code response message are configurable, and are not limited herein.
For example, the upper limit of the normal signaling rate threshold range is 1000MPS. The signaling rate in the IMS-HSS direction reaches 3000MPS, wherein UAR message rate reaches 1500MPS, call message rate reaches 1200MPS, and the rest message rate reaches 300MPS. The DRA intercepts all UAR messages. Since the call message rate 1200MPS still exceeds the upper 1000MPS of the normal signaling rate threshold range, some call messages may also be intercepted by the DRA. After receiving the Diameter error code response message including 4888 error code sent by the DRA, CSCF unit and/or AS sends SIP error code response message including 404 error code and registration interval duration information to the calling terminal in the registration flow. In addition, in the call flow, the CSCF element and/or the AS sends a SIP error code response message including 500 error codes to the calling terminal. After receiving the SIP error code response message comprising the 500 error codes, the calling terminal continues to initiate a call through the CS network, thereby ensuring that the call service between the calling terminal and the called terminal can be normally performed.
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 delay or call the called terminal through the CS network.
In step S202, the calling terminal delays initiation of a registration request or calls the called terminal through the circuit switched CS network according to the SIP error code response message.
If the calling terminal is in the registration process, the calling terminal delays the initiation of the registration request 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 make corresponding processing according to the received SIP error code response message, namely, delay the initiation of a registration request or call the called terminal through a CS network, thereby reducing the signaling load of the HSS or restoring the call service, and further reducing the adverse effect of signaling storm on service processing.
In some examples, the SIP error code response message includes a first error code and registration interval duration information. The first error code characterizes a signaling storm in the home subscriber server HSS direction during registration. If the SIP error code response message comprises a first error code, the calling terminal delays to initiate a registration request.
The delay initiation of the registration request by the calling terminal in step S202 in the above embodiment may be specifically implemented as follows: 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 interval indicated by the registration interval duration information. The registration interval duration may be set according to a specific working scenario and working requirement, and is not limited herein. For example, the registration interval duration may be 30 minutes, the calling terminal may initiate the registration request after 30 minutes, or the calling terminal may initiate the registration request at periodic intervals of 30 minutes.
The related information of the first error code may be referred to the related description in the above embodiment, and will not be described herein.
In other embodiments, the SIP error code response message includes a second error code. The second error code characterizes the signaling storm occurring in the home subscriber server HSS direction during the call. If the SIP error code response message comprises the second error code, the calling terminal calls the called terminal through the CS network. Thereby restoring call traffic.
The related information of the second error code may be referred to the related description in the above embodiment, and will not be described herein.
In the above embodiment, the calling terminal calls the called terminal through the CS network may be implemented in two ways, but is not limited to the following:
the first way is: if the calling terminal is in a Voice over Long-Term Evolution (VoLTE) network, the calling terminal falls back to a CS network, and the called terminal is called through the CS network.
The second way is: if the calling terminal is in the CS network, the calling terminal sends a data deleting instruction to the HSS/HLR of the called terminal, and calls the called terminal through the CS network. The data deleting instruction is used for indicating to delete the called anchor template data of the called terminal. If the called anchor 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 to inquire the called terminal, so that the intercepted call in the VoLTE network can 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 is restored to be 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 to add the called anchor template data of the called terminal. The added called anchor template data of the called terminal can promote the calling terminal to dial the called terminal using the VoLTE network under the CS network to enter the IMS domain through the MGCF to inquire the called terminal, so that the IMS-HSS equipment normally bears the service.

It should be noted that, in fig. 5, relevant steps of the calling I/S-CSCF element and the calling AS between the calling terminal and the called I/S-CSCF element are omitted.
In step S401, the calling terminal sends a call request message to the called I/S-CSCF unit.
It should be noted that, step S401 omits the message transmission procedure between the calling I/S-CSCF element and the calling AS between the calling terminal and the called I/S-CSCF element.
In step S402, the called I/S-CSCF element sends the LIR message to the called DRA.
The called DRA sends an instant location response (Location Immediate Answer, LIA) message to the called I/S-CSCF element in step S403.
The LIA message belongs to a Diameter protocol error code response message, and carries an error code, such as 4888 error code.
In step S404, the called I/S-CSCF element sends the SIP error code response message to the calling terminal.
The SIP error code response message carries the second error code.
It should be noted that, step S404 omits the message transmission procedure between the calling I/S-CSCF element and the calling AS between the calling terminal and the called I/S-CSCF element.
In step S405, the calling terminal calls the called terminal through the CS network.
Specifically, the step of calling the called terminal may be performed through the calling MSC.
