Detailed Description
In order to enable a person skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
At present, enterprises and individual clients rent a large amount of broadband for telecom operators, the purpose of products is changed without permission, and the self-used uplink bandwidth is aggregated to form a large bandwidth for traffic management, so that the security is lower.
In order to avoid the above, embodiments of the present invention propose a solution, which is described in detail below with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present invention proposes a PCDN violation service detection method, which is applied to an electronic device, and includes:
s100: for each target network device in an operator network, acquiring broadband internet surfing data generated by user internet surfing at a preset time point from the target network device; the target network equipment is used for distributing IP addresses to broadband Internet users;
wherein the target network device is a BAS/MSE network device; the preset time point may be any time point, for example, the preset time point is a time point after the electronic device is connected, and the broadband internet data is real-time broadband service online information on the BAS/MSE network device.
Broadband internet data such as broadband account numbers, IP addresses, MAC addresses, internet VLANs, BAS/MSE Loopback addresses, BAS ports, etc.
S101: determining at least one internet surfing behavior characteristic according to the acquired broadband internet surfing data;
the internet surfing behavior characteristics comprise the following parts or all of the following parts:
the same logical internet address uses the number of different broadband account numbers;
The number of times of dialing the same broadband account number;
the number of times of dialing the same broadband account number under the same MAC address;
the type of the IP address used in the broadband account dialing connection process;
upstream total flow rate for the same logical internet address.
The same logical internet address uses the number of different broadband accounts to indicate that the user uses the same internet path to internet through different broadband accounts, so that a plurality of broadband are installed at the same logical internet address. The ordinary family is 2-8 families, so the family account does not need to install a plurality of broadband. Therefore, the number of different broadband accounts used by the same logical internet address is counted, and whether the broadband account is a family account can be verified.
The same number of times of dialing the broadband account number indicates the number of times that the user uses the same broadband account number to surf the internet, and the number of times of surfing the internet at the same time of a common family is not too large, so that the same number of times of dialing the broadband account number is counted, and whether the broadband account number is the family account number can be verified.
The number of times of dialing the same broadband account number under the same MAC address, wherein the MAC address represents the address of a terminal, the address is set by the terminal in a factory, the number of times that a user uses the same terminal to surf the internet is represented, and the common call does not have too many times at the same time point, so that the number of times of dialing the same broadband account number under the same MAC address is counted, and whether the broadband account number is a family account number can be verified.
In general, the type of the address used for home configuration is not an IPV4 public network address, so that the type of the IP address used in the broadband account dial-up connection process can be verified whether the broadband account is a home account.
In general, the internet flow rate of the home cannot be larger than the downlink flow rate, and the uplink total flow rate of the same logical internet address can verify whether the broadband account is a home account.
Wherein the logical internet address is determined by:
and taking the Loopback address of the target network equipment, the port of the target network equipment and the address formed by the Internet VLAN in the broadband Internet surfing data as a logic Internet surfing address.
The target network device is BAS/MSE network device;
because the Loopback address of the BAS/MSE network equipment, the port of the target network equipment and the address formed by the Internet VLAN are unique, the unique address is used as the logical Internet address for distinguishing, and the number of different broadband accounts used by the same logical Internet address is studied.
S102: if the number of the target internet surfing behavior features exceeds the preset number, determining a target broadband account number using a broadband in the target internet surfing behavior features; the target internet surfing behavior characteristic is an internet surfing behavior characteristic which does not meet the household broadband limiting condition;
If the internet surfing behavior is characterized by the number of different bandwidths used by the same logical internet surfing address, the corresponding limitation condition of the home use bandwidth is that the number of different bandwidths used by the same logical internet surfing address exceeds the preset number;
if the internet behavior characteristic is the same number of times of dialing the broadband account, the corresponding family uses the broadband limiting condition to be that the same number of times of dialing the broadband account exceeds a first preset number of times;
if the internet behavior is characterized by the number of times of dialing the same broadband account number under the same MAC address, the corresponding household use broadband limiting condition is that the number of times of dialing the same broadband account number under the same MAC address exceeds a second preset number of times; for example, the second preset number of times is 1 time;
if the internet behavior characteristic is the IP address type used in the broadband account dial-up connection process, the corresponding limitation condition of the home use broadband is that the IP address type used in the broadband account dial-up connection process is the IPv4 public network type;
if the internet behavior is characterized by the uplink total flow rate of the same logical internet address, the corresponding household use broadband limiting condition is that the uplink total flow rate of the same logical internet address is larger than the downlink total flow rate.
Further, the number obtained by weighted summation of the numbers may be compared with a preset number. For example, each target internet surfing behavior feature is weighted to obtain a number.
The formula is as follows:
Q＝∑K i ×T i
wherein K is i Weight of internet surfing behavior characteristic of ith target, T i The internet surfing behavior characteristic of the ith target. The weight of each target internet behavior feature is preset, for example, the number of different broadband accounts used by the same logical internet address exceeds the preset number, then K i ×T i Is 0.5 times 1; the number of dialing times of the same broadband account number exceeds the first preset number, then K i ×T i Is 0.3 times 1; phase under the same MAC addressThe number of dialing times of the same broadband account number exceeds a second preset number of times, then K i ×T i Is 0.3 times 1; the IP address type used in the broadband account dial-up connection process is IPv4 public network type, then K i ×T i Is 0.7 times 1; the uplink total flow rate of the same logical Internet address is larger than the downlink total flow rate, then K i ×T i Is 0.5 times 1; then the number is 2.3 compared to the preset number.
The first preset number of times may be the number of times of use of a general household, for example, 4 times, or the maximum value of the limit of the BAS/MSE to a single user. Of course, if the usage number of the ordinary family corresponds to a weight of 0.3, the maximum value of the bas/MSE to the single user restriction corresponds to a weight of 0.8.
The foregoing is merely exemplary, and the present invention is not limited thereto.
S103: for each target broadband account, if the account type of the target broadband account is a family account, determining that PCDN (physical downlink packet access) violation service exists in the target broadband account;
s104: if the account type of the target broadband account is an enterprise account, detecting whether PCDN violation business exists in the target broadband account according to the business type and the account use information of the target broadband account.
In detail, if the company service type of the target broadband account is not a preset type and the internet geographic address and the installed address in the account usage information of the target broadband account are consistent, determining that the PCDN violation service does not exist in the target broadband account; the preset type is a company service type without using requirements; the use requirement comprises a part or all of the same-address multi-dialing, the public network single stack and the public network double stack;
if the service type of the target broadband account is a preset type, the target broadband account has authentication information required by the account of the preset type, and the internet geographic address and the installed address in the account use information of the target broadband account are consistent, determining that PCDN (physical digital code division multiple access) illegal services do not exist in the target broadband account;
if the service type of the target broadband account is a preset type, and the target broadband account does not have authentication information required by the account of the preset type or the internet geographic address and the installed address in the account use information of the target broadband account are inconsistent, determining that PCDN (physical digital code division multiple access) violation service exists in the target broadband account.
The internet geographic address may determine an internet physical address by calling data of the CRM system according to a logical internet address of the target broadband account, that is, determining the internet physical address by using information such as a Loopback address of the target network device, a port of the target network device, an installation position of the device on the internet VLAN, an area using the device, and the like, for example, a number of a certain cell a building 102.
The installed address is recorded in the data of the CRM system by calling the data of the CRM system, so that the corresponding installed address can be directly found according to the target broadband account number.
Wherein, the preset type is science and technology type, and the non-preset type can be a hospital, a hotel and the like. The authentication information required by the account of the preset type can be a qualification certificate and an information security commitment.
In detail, the information such as user identity, business use, operation qualification and the like of the target broadband account can be queried through CRM system (customer relationship management) data.
The method comprises the steps that through a CRM system (customer relationship management), if the account type of a target broadband account is found to be a family account, determining that PCDN violation service exists in the target broadband account;
if the account type of the target broadband account is determined to be an enterprise account, judging whether the service type is scientific and technological, judging whether the internet geographic address in the account use information of the target broadband account is consistent with the installed address, and if the internet geographic address in the account use information of the target broadband account is not scientific and technological, judging that the internet geographic address in the account use information of the target broadband account is consistent with the installed address, and no PCDN illegal service exists; if the network address is scientific and technological, checking whether the network address is qualified, if the network address is qualified, the network address is consistent with the installed address, and if the network address is inconsistent with the installed address, the network address is inconsistent with the installed address.
