Detailed Description
Before describing the spam identification method according to the embodiment of the present invention in detail, the principle of the pseudo base station and the principle of the pseudo base station transmitting information will be described first.
Fig. 1 is a schematic diagram of a pseudo base station; as shown in fig. 1, the pseudo base station performs configuration by using the scanned information of the peripheral strong signal cells, so that the terminal is attached to the pseudo base station, and performs a location update procedure during attachment, and reports the user identification information to the pseudo base station; and after the pseudo base station acquires the user identification information, triggering a short message sending process.
Fig. 2 is an interaction diagram of a short message center sending a short message to a terminal; as shown in fig. 2, the short message center (SC) transmits a short message to the terminal (MS); after receiving the short message, the terminal sends a delivery report to the short message center.
In general, a short message sent through a short message center carries a timestamp, and the time represented by the timestamp is time zone information of the short message center. However, the time zone carried in the short message sent by the pseudo base station is not the time zone of the short message center entity in the actual network because the pseudo base station does not simulate the short message center entity. Based on this, the following examples of the present invention are proposed.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example one
The embodiment of the invention provides a junk information identification method which is applied to a terminal. Fig. 3 is a schematic flowchart of a spam identification method according to a first embodiment of the present invention; as shown in fig. 3, the method includes:
step 301: and receiving the short message, and extracting the first time zone information in the short message.
Step 302: and comparing whether the first time zone information is consistent with second time zone information in time synchronization service, and judging whether the short message is junk information sent by the pseudo base station based on a comparison result.
In this embodiment, before receiving the short message, the method further includes: and after accessing the mobile communication network, obtaining and recording the second time zone information based on the time synchronization service. The access mobile communication network can be accessed to the mobile communication network for the first time after the terminal is started; further based on the Time synchronization service, as an embodiment, the Time synchronization service may be a Network Identification and Time Zone (NITZ) Time synchronization service, and records Time Zone information in the MMInformation message as the second Time Zone information.
In this embodiment, the received short message includes a timestamp, and the time indicated by the timestamp is time zone information of the short message center, and then the time zone information in the short message is extracted as the first time zone information.
In this embodiment, as a first implementation manner, the determining whether the short message is spam sent by the pseudo base station based on the comparison result includes: and when the comparison result shows that the first time zone information is inconsistent with the second time zone information in the time synchronization service, judging that the short message is junk information sent by the pseudo base station.
As a second embodiment, the determining whether the short message is spam sent by a pseudo base station based on the comparison result includes: and when the comparison result shows that the first time zone information is consistent with the second time zone information in the time synchronization service, judging that the short message is not the junk information sent by the pseudo base station.
Specifically, since the short message center and the access network device of the mobile communication network use the same clock source, the second time zone information recorded when accessing the network should be consistent with the first time zone information carried in the short message. If the short message is issued by a short message center of the mobile communication network, the first time zone information and the second time zone information are kept consistent, and based on a comparison result of the consistency of the first time zone information and the second time zone information, the short message is judged to be not the junk information sent by the pseudo base station, but a normal short message. If the short message is not sent by the short message center of the mobile communication network but sent by the pseudo base station, because the pseudo base station does not simulate the short message center entity, and the time zone carried in the sent short message is not the time zone of the short message center entity in the actual network, the short message is judged to be the junk information sent by the pseudo base station based on the comparison result of the inconsistency of the first time zone information and the second time zone information.
By adopting the technical scheme of the embodiment of the invention, whether the short message is the junk information sent by the pseudo base station is identified by comparing whether the first time zone information in the received short message is consistent with the second time zone information in the time synchronization service, so that the pseudo base station can not construct a clock source which is the same as the access network equipment or the short message center, and the accuracy of junk information identification is greatly improved.
Example two
The embodiment of the invention provides a junk information identification method which is applied to a terminal. Fig. 4 is a flowchart illustrating a spam identification method according to a second embodiment of the present invention; as shown in fig. 4, the method includes:
step 401: and executing a cell switching monitoring process.
Step 402: and when cell switching operation and position updating operation are monitored, receiving a short message and extracting first time zone information in the short message.
Step 403: judging whether the first time zone information is consistent with second time zone information in the time synchronization service, and if so, executing step 404; when the determination result is negative, step 405 is executed.
Step 404: and judging that the short message is not the junk information sent by the pseudo base station.
Step 405: and judging that the short message is junk information sent by the pseudo base station.
In this embodiment, before the performing the cell handover monitoring procedure, the method further includes: and after accessing the mobile communication network, obtaining and recording the second time zone information based on the time synchronization service. The access mobile communication network can be accessed to the mobile communication network for the first time after the terminal is started; further based on the time synchronization service, as an embodiment, the time synchronization service may be a NITZ time synchronization service, which records time zone information in the MMInformation message as the second time zone information.
In this embodiment, after accessing the mobile communication network, a cell handover monitoring procedure is executed, specifically, whether a terminal initiates a cell handover operation and a location update operation is monitored in real time on a wireless channel. And after the cell switching and the position updating are monitored, extracting first time zone information from the received short message.
Because the short message center and the access network device of the mobile communication network adopt the same clock source, the second time zone information recorded when the network is accessed is consistent with the first time zone information carried in the short message. If the short message is issued by a short message center of the mobile communication network, the first time zone information and the second time zone information are kept consistent, and based on a comparison result of the consistency of the first time zone information and the second time zone information, the short message is judged to be not the junk information sent by the pseudo base station, but a normal short message. If the short message is not sent by the short message center of the mobile communication network but sent by the pseudo base station, because the pseudo base station does not simulate the short message center entity, and the time zone carried in the sent short message is not the time zone of the short message center entity in the actual network, the short message is judged to be the junk information sent by the pseudo base station based on the comparison result of the inconsistency of the first time zone information and the second time zone information.
By adopting the technical scheme of the embodiment of the invention, whether the short message is the junk information sent by the pseudo base station is identified by comparing whether the first time zone information in the received short message is consistent with the second time zone information in the time synchronization service, so that the pseudo base station can not construct a clock source which is the same as the access network equipment or the short message center, and the accuracy of junk information identification is greatly improved.
