The method for determining the pseudo base station, provided by the embodiment of the invention, comprises the steps of sending data to a preset network station, and acquiring an internet protocol IP address set when the data can be transmitted, wherein the IP address set is a set of IP addresses respectively corresponding to routers through which the data pass in the transmission process, a precondition guarantee is provided for identifying the pseudo base station based on the IP address of the router through which the data pass in the transmission process, and whether the base station currently located is the pseudo base station is determined based on the IP address set, so that whether the base station currently located by a mobile terminal is the pseudo base station is accurately and effectively determined according to the IP address of the router through which the data pass in the transmission process, the communication with the pseudo base station is avoided, and the property safety, the information safety and the like of a user are effectively protected.
The following describes a method for determining a pseudo base station in an embodiment of the present invention in detail, specifically as follows:
in step 110, data is sent to a preset network station, and when the data can be transmitted, an internet protocol IP address set is obtained, where the IP address set is a set of IP addresses corresponding to routers through which the data passes in the transmission process.
Preferably, the method further comprises: and when the data can not be transmitted, determining the current base station as a suspected pseudo base station.
Preferably, the acquiring internet protocol IP addresses corresponding to respective routers through which the data passes in the transmission process includes: and acquiring IP addresses corresponding to the routers through which the data pass in the transmission process based on the time to live value TTL in the IP data packet of the data.
Specifically, the preset network station needs measures such as identity authentication or encryption to prevent the fake station by the pseudo base station, wherein when detecting whether the base station where the mobile terminal is located is the pseudo base station, the mobile terminal may obtain an IP address set, for example, denoted as an IP address set a, of all routers that the mobile terminal passes through in the normal data transmission process by sending data to the pre-designed network station, and since an IP address or an IP address range of each router in the core network of the regular operator is relatively fixed (i.e., preset), it may detect whether the base station where the mobile terminal is currently located is the pseudo base station according to the IP address set a and the IP address or the IP address range of each router in the core network of the regular operator.
Further, when network abnormal conditions such as network interruption and network instability occur, data transmission between the mobile terminal and the preset network station may not be possible, when the base station where the mobile terminal is currently located is a pseudo base station, data transmission between the mobile terminal and the predetermined network site may not be performed, as in the case shown in fig. 2, and thus, when data transmission between the mobile terminal and the predetermined network station is not possible, the base station where the mobile terminal is currently located may be determined as a suspected fake base station, then the reason why the data transmission cannot be carried out is deeply analyzed to determine whether the data transmission cannot be carried out due to the network abnormity, if the data transmission is not caused by the network abnormality, it can be determined that the data cannot be transmitted because the base station where the mobile terminal is currently located is the pseudo base station, so that the base station where the mobile terminal is currently located can be determined as the pseudo base station.
Further, when the mobile terminal sends data to the preset network station, in the transmission process of the data, the IP addresses corresponding to the routers through which the data pass in the transmission process can be obtained through the time to live TTL in the IP data packet of the data. Because each IP packet has a TTL (Time To Live) field, the IP address of each router in the normal data transmission process can be obtained according To an ICMP (Internet Control Message Protocol) and the TTL in the IP packet header, specifically, the mobile terminal first sends an IP packet with TTL of 1 (which sends out 3 packets with 40 bytes, where the contents in the 3 packets are the source address, the destination address and the Time tag when sending out the IP packet) To a preset network site, when the first router on the path receives the IP packet, the router subtracts TTL of 1, and at this Time, TTL of 0 is changed To 0, so the router drops the IP packet and returns an "ICMP Time timeout" Message, where the timeout Message includes the source address of the IP packet, and the source address of the IP packet, After receiving the timeout message, the mobile terminal knows that the router is on the path, and then sends out another data packet with TTL of 2 through "route trace", so as to find the 2 nd router, and so on, the mobile terminal finds another router by adding 1 to the TTL of the data packet sent each time, and this repeated action continues until the data packet arrives at the predetermined network site, and after the data packet arrives at the predetermined network site, the predetermined network site does not send back the "ICMP time timeout" message because it is the destination, so as to finally obtain the IP addresses corresponding to the routers through which the data passes in the transmission process.
In step 120, it is determined whether the base station currently located is a pseudo base station based on the IP address set.
Preferably, the determining whether the base station currently located is a pseudo base station based on the IP address set includes: detecting the legality of the IP address set according to a prestored legal IP address database; and determining whether the current base station is a pseudo base station or not according to the detection result.
Preferably, the detecting the validity of the IP address set according to the pre-stored valid IP address database includes: detecting whether an IP address belonging to a legal IP address database exists in the IP address set; if the IP address set does not have the IP address belonging to the legal IP address database, determining the IP address set as an illegal IP address set; and if the first IP address set contains the IP addresses belonging to the legal IP address database, determining the IP address set as a suspected illegal IP address set.
Preferably, determining whether the current base station is a pseudo base station according to the detection result includes: if the IP address set is an illegal IP address set, determining that the current base station is a pseudo base station; and if the IP address set is a suspected illegal IP address set, determining whether the current base station is a pseudo base station or not based on the sub-IP address set before the IP address in the legal IP address database is reached.
Preferably, the determining whether the base station currently located is a pseudo base station based on the sub IP address set before reaching the IP address belonging to the legal IP address database includes: detecting whether the IP address which does not belong to the legal IP address database exists in the sub-IP address set; and if the IP address does not belong to the legal IP address database, determining that the current base station is the pseudo base station.
Specifically, the IP address or IP address range of each router in the core network of the regular operator is preset, so that the IP address or IP address range of each router in the core network of the regular operator can be stored in a corresponding database, recorded as a legal IP address database, and loaded into the mobile terminal, that is, the legal IP address database is stored in the mobile terminal in advance, so that whether the current mobile terminal is in the pseudo base station can be detected according to the legal IP address database.
Further, when detecting whether the current mobile terminal is in the pseudo base station according to the legal IP address database, it may be determined whether the current mobile terminal is in the pseudo base station by detecting whether an IP address set (i.e., a set of IP addresses respectively corresponding to routers through which the mobile terminal transmits to a preset network station) belongs to the pre-stored legal IP address database. Specifically, if an IP address belonging to a legal IP address database does not exist in the IP address set, the IP address set is determined to be an illegal IP address set, that is, the base station where the mobile terminal is currently located is a pseudo base station, although the mobile terminal can normally perform data transmission with a preset network site, the mobile terminal can normally perform data transmission with the preset network site because the pseudo base station background automatically establishes a network to be connected to the internet for communication, but the network established by the pseudo base station background is not a base station or a core network of a mobile terminal operator, as shown in fig. 3; if the IP address set contains an IP address belonging to a legal IP address database, for example, IP address a, that is, the IP address a in the IP address set is an IP address in the legal IP address database, the IP address set is determined to be a suspected illegal IP address set, and the suspected illegal IP address set needs to be further detected to determine whether the current mobile terminal is in a fake base station.
Further, whether the current base station is a pseudo base station can be determined by detecting a sub-IP address set formed by all IP addresses before the IP address A is reached for the first time, wherein the sub-IP address set belongs to the IP address set, if all the IP addresses in the sub-IP address set are not IP addresses in a legal IP address database or IP addresses which do not belong to a legal IP address database exist in the sub-IP address set, the current base station where the mobile terminal is located is determined to be the pseudo base station, in this case, the mobile terminal can normally transmit data with a preset network station because the pseudo base station automatically establishes a local network and the automatically established local network is accessed to an operator core network, as shown in FIG. 4, namely, the mobile terminal is accessed to the operator core network through the local network automatically established by the pseudo base station and then is accessed to the Internet through the operator core network, the data transmission is carried out with the preset network station, in this case, the local network built by the pseudo base station by itself needs to be accessed into the core network of the operator, at least one router which cannot be controlled by the pseudo base station necessarily exists, and the IP address of the router is the IP address in the legal IP address database, specifically, when the mobile terminal sends data to the preset network station, although the pseudo base station can build the network by itself through the router controlled by the pseudo base station, so that the TTL can be used for doing hands and feet, because the local network built by the pseudo base station by itself needs to be accessed into the core network of the operator, as shown in FIG. 4, at least one router which cannot be controlled by the pseudo base station exists in the local network built by itself by the pseudo base station for accessing the core network or the Internet, after all, the pseudo base station cannot directly plug the network cable into the preset network station, but only can connect the preset network station through the intermediate network, i.e. must communicate with the predetermined network station via an intermediate network provided by the corresponding network provider, so that there must be at least one router which the pseudo base station cannot control and the IP address of the router.
Further, if all the IP addresses in the sub-IP address set are IP addresses in a legal IP address database, it is determined that the current base station where the mobile terminal is located is a regular base station of the operator, that is, the mobile terminal is not currently located in a pseudo base station, in this case, the mobile terminal accesses the internet through a core network of the operator to perform data transmission with a preset network site, as shown in fig. 5.
