Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Referring to fig. 2, fig. 2 is a flowchart illustrating a communication method according to a first embodiment of the present invention, and as shown in fig. 2, the communication method according to the embodiment of the present invention includes the following steps:
s101, the mobile terminal detects whether a target base station establishing communication connection with the mobile terminal is a pseudo base station.
Optionally, in some embodiments of the present invention, a specific implementation manner of the mobile terminal detecting whether the target base station establishing the communication connection with the mobile terminal is the pseudo base station may be:
the mobile terminal obtains the base station parameters of the target base station, wherein the base station parameters include but are not limited to: the method comprises the steps of obtaining a location area code LAC, a transmitting power, a cell selection parameter C1 and a cell reselection parameter C2 of a base station, judging whether a base station parameter of a target base station is matched with a base station parameter of a pre-stored operator real base station, and if the base station parameter of the target base station is not matched with the base station parameter of the pre-stored operator real base station, determining that the target base station is a pseudo base station by a mobile terminal. The operators include, but are not limited to, china unicom, china telecom, and china mobile.
And S102, if so, the mobile terminal resides in and locks the target base station.
The mobile terminal resides and the target base station can ensure that the mobile terminal cannot be switched to other base stations within a preset time period.
S103, in a preset time period, the mobile terminal generates and sends N random access request messages to the target base station, and does not respond to M immediate assignment messages sent by the target base station in the preset time period,
wherein the N random access request messages each carry 1 random number, each of the random numbers is different from the other random numbers, the M immediate assignment messages are sent by the target base station after receiving the N random access request messages, the immediate assignment messages are used to allocate an independent dedicated control channel to the mobile terminal, N, M is an integer greater than 1, and N is greater than or equal to M.
Specifically, the existing pseudo base station mainly aims at users accessing to a Global system for Mobile Communication (GSM), and mainly aims at high popularization rate and a large number of users of the GSM network, and in addition, the protection of the GSM network is not perfect. The pseudo base station is mainly used for cheating and annoying the user by sending the short message. For example, "bank account for industry and commerce: 6222 xxx × 516, house name: yang Min, handling incoming telegram. "3/5/2013, many citizens in Hengyang city, Hunan province received such a short message, and the number of the mobile phone sending the short message is displayed as 15 xxx 868", which is the number of the mobile phone of the Xingyang city, Xiaoping (chemical name). In practice, however, the short message is not a Chinese zodiac.
The GSM terminal needs to establish a dedicated independent dedicated Control Channel (SDCCH) in idle state to receive the short message, that is, a dedicated timeslot and frequency point are needed to provide service. Because the GSM system belongs to a frequency division + time division system, and the frame structure of the GSM determines that each frequency point of the GSM has only at most 8 time slots, unlike the code division system, if a large number of users continuously request the network to allocate the SDCCH channel, the base station may have insufficient channel resources, and cannot provide services for other users. The 3GPP protocol specifies that to acquire dedicated SDCCH channel resources, the terminal must send random access request information, i.e. a channel request message, with maximum power, as shown in fig. 2-1, where fig. 2-1 is a message structure of the channel request message. Here, RANDOM REFERENCE is a RANDOM number generated by a terminal, and the RANDOM numbers generated by different terminals are different.
After receiving the random access request of the terminal, the base station assigns a dedicated SDCCH channel to the terminal through an immediate assignment message, namely an immediateasignment message, and carries a random number generated by the terminal in the immediateasignment message, the terminal determines whether the immediatassignment is assigned to the SDCCH channel by comparing the random number, if not, the terminal will try continuously until the maximum times specified by the network and the time-out of a timer are reached, the random access failure is reported, and the cell reselection is triggered.
Based on the characteristics of few GSM channel resources and different random numbers carried by random access requests of different terminals, the embodiment of the invention utilizes the prior pseudo base station identification technology to find the pseudo base station, reside and lock the pseudo base station on the pseudo base station, then generates different random numbers at preset intervals (the period can be 1s), and transmits the random numbers carried by the channel request to the pseudo base station uninterruptedly with the maximum power. After receiving the random access requests, the pseudo base station must respond and allocate a dedicated SDCCH channel. Because the GSM channel resources are limited, especially for the pseudo base station, the channel resources are more limited, and because the random numbers in the channel request messages carried by the terminals are different, the pseudo base station is different from the pseudo base station in terms of requesting resources, if the terminals continuously send the channel request, the situation that the pseudo base station SDCCH channel resources are not enough is necessarily caused, so that the SDCCH channel resources cannot be allocated to other terminals residing in the pseudo base station, and further fraud cannot be sent, and a short message is sent to other terminals, thereby achieving the purpose of paralysis of the pseudo base station.
Optionally, in some embodiments of the present invention, a specific implementation manner of generating and sending N random access request messages to the target base station within a preset time period may be:
the mobile terminal determines N random numbers which are different from each other and N periods in the preset time period, generates a random access request message carrying 1 random number of the N random numbers in each period of the N periods, and sends the random access request message to the target base station.
Optionally, in some embodiments of the present invention, a specific implementation manner of generating and sending N random access request messages to the target base station within a preset time period may also be:
the mobile terminal determines N cycles in the preset time period; and generating a random number in each of the N periods, generating a random access request message carrying the random number, and sending the random access request message to the target base station.
Optionally, in some embodiments of the present invention, before the mobile terminal generates and sends N random access request messages to the target base station within a preset time period, the mobile terminal may further send an inquiry request for inquiring the number of independent dedicated control channels included in the target base station to the target base station; receiving an inquiry response which is generated by the target base station and carries the number of independent dedicated control channels, wherein the number of the independent dedicated control channels is M; and determining the size of the N according to the number M of the independent dedicated control channels.
Compared with the scheme that the mobile terminal does not reside in the pseudo base station after recognizing the pseudo base station in the prior art, the embodiment of the invention has the following advantages that: after determining a pseudo base station in wireless communication with a mobile terminal, a mobile terminal resides and locks the pseudo base station in a preset time period, generates and sends N random access request messages to the pseudo base station, and does not respond to M immediate assignment messages sent by the pseudo base station in the preset time period. It can be seen that after receiving the random access request message, the pseudo base station inevitably needs to respond, and allocates different independent dedicated control channels to the mobile terminal according to different random numbers, and since the channel resources of the pseudo base station are limited, the limited channel resources of the pseudo base station are occupied by the same mobile terminal, which is beneficial to reducing the available channel resources of the pseudo base station, thereby reducing the number of mobile terminals residing in the cell of the pseudo base station, and improving the communication security of the cell.

Specifically, the specific implementation of each unit may refer to the description of the relevant steps in the embodiments corresponding to fig. 2 to fig. 4, which is not described herein again.
Compared with the scheme that the mobile terminal does not reside in the pseudo base station after recognizing the pseudo base station in the prior art, the embodiment of the invention has the following advantages that: after determining a pseudo base station in wireless communication with a mobile terminal, a mobile terminal resides and locks the pseudo base station in a preset time period, generates and sends N random access request messages to the pseudo base station, and does not respond to M immediate assignment messages sent by the pseudo base station in the preset time period. It can be seen that after receiving the random access request message, the pseudo base station inevitably needs to respond, and allocates different independent dedicated control channels to the mobile terminal according to different random numbers, and since the channel resources of the pseudo base station are limited, the limited channel resources of the pseudo base station are occupied by the same mobile terminal, which is beneficial to reducing the available channel resources of the pseudo base station, thereby reducing the number of mobile terminals residing in the cell of the pseudo base station, and improving the communication security of the cell.
