Currently, mobile communication technology is in the 5G age after 2G, 3G and 4G development, and 5G is short for fifth generation mobile communication, which provides at least ten times of peak rate of 4G, millisecond transmission delay and trillion connection capability with a brand new mobile communication system architecture, so as to realize new jump of network performance. IMS is an abbreviation for multimedia subsystem (IP Multimedia Subsystem), which is an all IP based complete voice solution, in mobile core networks, IMS can act as the core network for voice services of 5G, where VoNR is called in 5G. In a practical scenario, only VoNR needs to be considered in 5G communication, i.e. the access network is accessed from NR. The P-CSCF (Proxy Call Session Control Function ) is the portal for IMS network SIP (Session initialization Protocol, session initiation protocol) signaling, i.e. all SIP (Session initialization Protocol, session initiation protocol) signaling from the user has to go through the P-CSCF network element into the IMS network, which is responsible for receiving requests sent by the access network to the IMS network and forwarding to the internal IMS network element. The SBC (Session Border Controller) session border controller is an IP service gateway of the IMS network, that is to say, all the traffic data of the VoNR passes through the network element, so as to implement access, intercommunication and security protection of the data.

In the process of filtering the data of the VoNR, it is first required to identify that those data are VoNR, and the conventional processing method generally relates to the 5G service data through the signaling of 5G, marks the information of 5QI (5G Quality of Service Identifier,5G quality of service standard) and DNN (Data Network Name ) to the end of the 5G service data through the association, and then judges that the data are VoNR data according to the marked DNN is IMS and the 5QI is 1 or 2, and then filters the data. However, the filtering effect depends on the association rate, the implementation of the association technology is complex, the association needs to be performed by using the data of the N3 or N9 port as the service data, and if the service data is the data of the N6 port, the association cannot be performed, and the data of the VoNR cannot be identified. Aiming at the problems that the filtering of the VoNR service data of 5G needs to be firstly carried out and the data of an N9 interface cannot be associated and the filtering cannot be identified, the application provides the filtering method, the system and the server of the VoNR service data.

For the sake of understanding the present embodiment, first, a method for filtering VoNR data disclosed in the present embodiment is described in detail, as shown in fig. 1, where the method includes:

step S101, voNR service data under a 5G network is collected in real time, and signaling data containing a session initiation protocol is determined according to the VoNR service data;

step S102, analyzing the signaling data to obtain a first IP address of a session border controller network element corresponding to the signaling data;

step S103, determining a source IP address and a destination IP address corresponding to the service data by using the first IP address, and determining a configuration rule by using the source IP address and the destination IP address;

step S104, determining an inner layer IP address corresponding to the VoNR service data as a second IP address by using a configuration rule, and acquiring a matching result of the second IP address and the first IP address;

step S105, the filtering result of the VoNR service data is determined by using the matching result.

When in actual execution, firstly, collecting service data under a 5G network in real time; then, carrying out protocol identification on the collected service data to identify signaling data of a Session Initiation Protocol (SIP); then analyzing the business data of some SIP protocol with specific characteristics to analyze the first IP address of the SBC network element; configuring the acquired first IP address of the SBC network element into a source IP and a destination IP, and acquiring corresponding configuration rules thereof; and then determining the inner layer IP address corresponding to the VoNR service data as a second IP address by using a configuration rule, and acquiring a matching result of the second IP address and the first IP address, thereby realizing that the inner layer IP of the resolved VoNR service data is dematched with the IP of the SBC network element. And finally, determining a filtering result of the VoNR service data according to the matching result, and dynamically and automatically deploying the IP address of the SBC network element to filtering equipment, thereby filtering the VoNR service data.

Therefore, the method converts the filtering of the VoNR service data into the filtering of the IP address, does not need to carry out signaling and service association, avoids complex association technology, and eliminates the influence of the association technology on the filtering effect; the method is simple and feasible and can be operated strongly.

In one embodiment, the step S101 of collecting the VoNR service data in the 5G network in real time and determining the signaling data including the session initiation protocol according to the VoNR service data, as shown in fig. 2, includes:

step S201, a bearing channel constructed under a 5G network is established and acquired;

step S202, when detecting that a user dials a VoNR phone, acquiring VoNR service data corresponding to the VoNR phone in real time, and acquiring the VoNR service data in real time through a bearing channel;

step S203, the protocol identification is carried out on the VoNR service data to determine the session initiation protocol, and the signaling data containing the session initiation protocol is obtained from the VoNR service data.

When determining signaling data, firstly establishing and acquiring a bearing channel constructed under a 5G network; when detecting that a user dials a VoNR phone, acquiring VoNR service data corresponding to the VoNR phone in real time, and acquiring the VoNR service data in real time through a bearing channel; and finally, carrying out protocol identification on the VoNR service data to determine a Session Initiation Protocol (SIP), and acquiring signaling data containing the SIP from the VoNR service data. In a specific implementation process, when detecting that a user dials a VoNR phone, step S202 of acquiring, in real time, voNR service data corresponding to the VoNR phone and acquiring, in real time, the VoNR service data through a bearer channel is shown in fig. 3, where the step S includes:

step S301, a data transmission interface between a base station and a user plane function node is obtained in a data interface provided by an operator with network deployment completed;

step S302, when detecting that a user dials a VoNR phone, acquiring VoNR service data corresponding to the VoNR phone in real time by utilizing a data transmission interface;

step S303, voNR service data is collected in real time through the bearing channel.

When a mobile phone user dials a VoNR call, a DNN (Data Network Name ) bearing tunnel is established in a 5G core network firstly, data generated by dialing the call can be transmitted to a UPF network element through the tunnel, and SPI signaling data can go away from a P-CSCF (Proxy Call Session Control Function proxy call session control function) network element to forward and interact with other network elements.

In one embodiment, the step S102 of parsing the signaling data to obtain the first IP address of the session border controller network element corresponding to the signaling data, as shown in fig. 4, includes:

step S401, analyzing the signaling data and obtaining SIP signaling data corresponding to the session border controller network element;

step S402, the IP address of the network element of the session boundary controller contained in the signaling data is obtained by utilizing the load characteristics corresponding to the SIP signaling data, and the IP address is determined as the first IP address.

In the embodiment, protocol identification is performed on the acquired data, and signaling data of the SIP protocol is identified; and judging whether the SIP signaling load comprises the IP of the SBC network element according to the specific characteristics of the SIP signaling load, further analyzing the IP of the SBC network element, and taking the IP as a first IP address.

In one embodiment, the step S103 of determining the source IP address and the destination IP address corresponding to the service data by using the first IP address and determining the configuration rule by using the source IP address and the destination IP address, as shown in fig. 5, includes:

step S501, obtaining a data type corresponding to a first IP address; wherein, the data type at least comprises: uplink data, signaling data and VoNR service data;

step S502, determining a source IP address and a destination IP address corresponding to the service data by utilizing the data type;

step S503, determining configuration rules according to the source IP address and the destination IP address.

In this embodiment, the obtained IP addresses of the SBC network elements are configured to the source IP and the destination IP, and the configuration rules of both are obtained at the same time. Specifically, when the data type is uplink data, the source IP address includes: an outer layer IP address of the base station and an inner layer IP address of the user terminal; the destination IP address is the outer IP address of the user plane function node; when the data type is signaling data, the target IP is the inner IP address of the proxy call session control function node; when the data type is VoNR service data, the destination IP is the inner IP address of the session border controller.

In one embodiment, the step S104 of determining the inner layer IP address corresponding to the VoNR service data as the second IP address by using the configuration rule and obtaining the matching result of the second IP address and the first IP address, as shown in fig. 6, includes:

step S601, analyzing the inner layer IP of the VoNR service data by utilizing configuration rules, and determining a second IP address according to analysis results;

step S602, the second IP address is matched with the first IP address according to the IP matching rules contained in the configuration rules, and a matching result is obtained.

In this embodiment, the inner layer IP of the VoNR service data is resolved by the configuration rule, and then the inner layer IP is used as the second IP address, and the second IP address is used to match the first IP address, thereby implementing the inner layer IP to match the IP of the SBC network element.

In one embodiment, the step S105 of determining the filtering result of the VoNR service data using the matching result, as shown in fig. 7, includes:

step S701, if the second IP address corresponding to the matching result is matched with the first IP address, obtaining a port corresponding to the configuration rule;

and step S702, the VoNR service data is downloaded by using the port, and then a filtering result of the VoNR service data is obtained.

Usually, before the dialed telephone is put through, the data of the SIP signaling will be interacted first to negotiate the IP of the SBC network element where the VoNR call service data is going, so that some specific SIP signaling can be analyzed to obtain the network element IP of the SBC, then the network element IP is deployed into IP rules, when the service data arrives, the IP of the inner layer is matched, if the service data can be matched, the service data can be identified as the VoNR service data, and then the service data is put down or filtered.

In one embodiment, the step of determining the filtering result of the VoNR service data using the matching result further includes: and if the second IP address corresponding to the matching result is not matched with the first IP address, filtering the VoNR service data to obtain a filtering result of the VoNR service data. If the data are not matched, the data are filtered in a truncating mode, and then the filtering result of the VoNR service data is obtained.

A VoNR data network element architecture diagram involved in a filtering method of VoNR data as shown in fig. 8; UE (User Equipment) in the figure is a user terminal, gNB is a base station, and service data between UPF (User Plane Function ) and gNB is service data of an N3 interface. AS (Application Server) is an application server, and performs data interaction with an S-CSCF (Serving-Call Session Control Function, serving call session control function) and an I-CSCF (interaction-Call Session Control Function, audit call session control function), respectively. On the basis, when a mobile phone user dials a VoNR phone, a DNN (Data Network Name ) bearing tunnel is firstly established in a 5G core network, data generated by dialing the phone is transmitted to a UPF network element through the tunnel, and sip signaling data is transmitted to a P-CSCF network element to interact with other network elements, as shown by a dotted line in fig. 8; the generated VoNR service data can go through the SBC network element to interact with the called mobile phone user. The service data between the gNB and the UPF, namely the service data of the N3 interface, is based on the gtp-u protocol. If the data is uplink data, the source IP of the outer layer is the IP of the gNB, the destination IP of the outer layer is the IP of the UPF, and the source IP of the inner layer is the IP of the UE; if the signaling is sip signaling, the destination IP of the inner layer is the IP of the P-CSCS; if the data is the service data of the VoNR call, the destination IP of the inner layer is the IP of the SBC.

Usually, before the dialed telephone is put through, the data of the SIP signaling will be interacted first to negotiate the IP of the SBC network element where the VoNR call service data is going, so that some specific SIP signaling can be analyzed to obtain the network element IP of the SBC, then the network element IP is deployed into IP rules, when the service data arrives, the IP of the inner layer is matched, if the service data can be matched, the service data can be identified as the VoNR service data, and then the service data is put down or filtered.

As can be seen from the SIP signaling data processing flow chart shown in fig. 9, the SIP signaling data processing flow chart mainly includes identifying SIP signaling and analyzing specific SIP signaling to obtain the IP geology of the SBC network element, and deploying the IP geology into IP rules. In an actual scenario, the relevant signaling data may be filtered by using the relevant data filtering module, which is not described herein.

The service data processing flow chart shown in fig. 10 mainly includes parsing an inner layer IP of service data, then de-matching an IP of an SBC, and filtering according to a matching result. In a practical scenario, the SIP signaling processing module may be used to perform data processing on the relevant signaling data.

In the above structure and flow chart, the filtering method of the VoNR data firstly collects the 5G core network data of the N3 interface between the gNB and the UPF from the operator and performs data access; then, carrying out protocol identification on the acquired data to identify signaling data of the SIP protocol; judging whether the SIP signaling load comprises the IP of the SBC network element according to the specific characteristics of the SIP signaling load, and further analyzing the IP of the SBC network element; configuring the acquired IP of the SBC network element into rules of a source IP and a destination IP; then analyzing the inner IP of the VoNR service data to match the IP of the SBC network element; and finally, filtering or downloading to a destination port according to the matching result.

According to the filtering method of the VoNR data, which is mentioned in the embodiment, the filtering of the VoNR service data is converted into the filtering of the IP address, and signaling and service association are not needed, so that a complex association technology is avoided, the influence of the association technology on the filtering effect is eliminated, and the method is simple and easy to implement and has strong operation.
