Detailed Description
The following detailed description of embodiments of the present invention will be made with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
In practical application, the pseudo base station inhales users through high-power signals: 1) the 2G pseudo base station sets a frequency point of an operator GSM (Global System for Mobile Communication), and transmits a high-power signal. When a user enters the coverage range of the pseudo base station, the user which is released and redirected to the 2G network by a 4G network RRC (Radio Resource Control) is easily sucked into the 2G pseudo base station; 2) the 4G pseudo base station and the 2G pseudo base station cooperate to do a case: a high-power 4G pseudo base station inhales a user and triggers the user to initiate a TAU (Tracking Area Update) request; the 4G pseudo base station rejects the TAU, and redirects the user to 2G by taking a GSM frequency point as high priority through RRC Connection Release (RRC Connection Release request); a high-power 2G pseudo base station inhales users.
An LTE (Long Term Evolution) network coverage Area is divided into a plurality of Tracking Areas (TAs) to facilitate confirmation of the location of a user. One TA may include one or more cells, and the network uses TAI (tracking Area identity) as the TA identifier, and one TA List includes 1 to 16 TAIs. When the UE (User Equipment) moves within the TA List, it is not necessary to perform TA List update; when the UE moves to a new TA List, the UE needs to initiate Tracking Area Update (TAU) to an MME (Mobility Management Entity).
When MME initiates TAU rejection, NAS (Non-access stratum) and RRC signaling release are carried out; or after initiating TAU project, triggering the user to initiate the attachment flow again, and releasing NAS and RRC signaling after attachment rejection. The above two processes lack the security, and both cannot ensure the reliability of the current access cell. When the RRC is released, redirection information is carried, the redirected target cell may be maliciously tampered, and the user is maliciously attacked.
In order to avoid redirection to a 2G pseudo base station, in a first embodiment of the present invention, the base station is required not to carry 2G frequency point information for redirection in an RRC Connection Release (RRC Connection Release message) after a TAU Reject (tracking area update Reject request); or, not carrying information for redirection; or the RRC connection release message carries information of a 2G frequency point and information of a 4G frequency point, and the priority of the 2G frequency point is lower than the priority of the 4G frequency point.
Example one
As shown in fig. 1, a redirection method according to a first embodiment of the present invention is applied to a base station, and includes:
In practical applications, each base station transmits a system broadcast message to the terminal. And the terminal detects the signal intensity of each base station based on the received system broadcast message, selects the base station with better signal intensity for random access and reselects the cell.
And 102, carrying out RRC connection process with the terminal.
Specifically, the terminal sends an RRC connection request to the base station; after receiving the request, the base station sends an RRC connection setting request to the terminal, and the terminal performs corresponding setting. After completion, the terminal transmits an RRC connection setup complete message to the base station.
And 103, receiving a tracking area updating request sent by the terminal.
When finding that the TAC (Tracking Area Code) of the cell to be accessed changes, the terminal sends a Tracking Area update request to the base station.
And 104, sending a tracking area updating rejection request to the terminal.
In the embodiment of the invention, the RRC connection release message does not carry information for redirection, namely, the RRC connection release message does not carry information of any frequency point, and the terminal selects the redirected frequency point.
Or, the RRC connection release message carries information of the frequency points of the different systems of the 2G system. Wherein, the different systems of the 2G system include but are not limited to: 3G systems, 4G systems, etc. For example, the RRC connection release message carries a frequency point list, which includes information of a 4G frequency point, information of a 3G frequency point, information of a 5G frequency point, and so on.
Or the RRC connection release message carries information of a 2G frequency point and information of a different system of the 2G system, and the priority of the 2G frequency point is lower than the priority of the frequency point of the different system of the 2G system.
For example, the RRC connection release message carries a frequency point list, which includes information of 4G frequency points and information of 2G frequency points, where the priority of the 4G frequency point is higher than that of the 2G frequency point. For another example, the RRC connection release message carries a frequency point list, which includes information of 4G frequency points, information of 2G frequency points, and information of 3G frequency points, where the priority of 4G frequency points is higher than the priority of 2G frequency points, and the priority of 3G frequency points may be higher than the priority of 2G frequency points or lower than the priority of 2G frequency points. Preferably, the priority of the 3G frequency point is lower than that of the 4G frequency point.
Because the RRC connection release message sent by the base station carries the information of the frequency points of the different systems of the 2G system, or the priority of the carried 2G frequency points is lower than that of the frequency points of the different systems, the terminal cannot locate the 2G pseudo base station, thereby ensuring smooth communication of users and improving the experience of the users.
Example two
As shown in fig. 2, the redirection method according to the second embodiment of the present invention is applied to a terminal, and includes:
In practical applications, each base station transmits a system broadcast message to the terminal. And the terminal detects the signal intensity of each base station based on the received system broadcast message, selects the base station with better signal intensity for random access and reselects the cell.
Specifically, the terminal sends an RRC connection request to the base station; after receiving the request, the base station sends an RRC connection setting request to the terminal, and the terminal performs corresponding setting. After completion, the terminal transmits an RRC connection setup complete message to the base station.
And when finding that the TAC of the cell to be accessed is changed, the terminal sends a tracking area updating request to the base station.
And step 204, receiving a tracking area update rejection request sent by the base station.
Wherein, the RRC connection release message does not carry the information for redirection; or, the RRC connection release message carries information of frequency points of the different systems of the 2G system; or the RRC connection release message carries information of a 2G frequency point and information of a frequency point of a different system of the 2G system, and the priority of the 2G frequency point is lower than the priority of the frequency point of the different system. The 2G system comprises but is not limited to a 3G system and a 4G system.
And step 206, redirecting according to the RRC connection release message.
Here, the terminal redirects to other cells according to the information in the RRC connection release message. Or the terminal selects the frequency point to be accessed according to the RRC connection release message and redirects the frequency point to other cells.
Because the RRC connection release message sent by the base station carries the information of the frequency points of the different systems of the 2G system, or the priority of the carried 2G frequency points is lower than that of the frequency points of the different systems, the terminal cannot locate the 2G pseudo base station, thereby ensuring smooth communication of users and improving the experience of the users.
EXAMPLE III
As shown in fig. 3, a redirection method according to the third embodiment of the present invention is applied to a terminal, and includes:
Wherein the predetermined time may be 3ms, etc.
For example, if the tracking area update rejection request is received, the 4G neighbor cell of the current serving cell is re-accessed without performing redirection to the 2G system.
In practical application, in order to further ensure the security of the user, the RRC connection release message does not carry information for redirection; or, the RRC connection release message carries information of frequency points of the different systems of the 2G system; or the RRC connection release message carries information of a 2G frequency point and information of a frequency point of a different system of the 2G system, and the priority of the 2G frequency point is lower than the priority of the frequency point of the different system.
In practical application, the RRC connection release message carries information of a 2G frequency point; or the RRC connection release message carries information of a 2G frequency point and information of a frequency point of a different system of the 2G system, and the priority of the 2G frequency point is higher than the priority of the frequency point of the different system. In contrast, when the 2G frequency point in the RRC connection release message is high priority information, the terminal may still perform corresponding processing according to whether a tracking area update rejection request is received within a predetermined time before the RRC connection release message.
Wherein the inter-system of the 2G system comprises: 3G system and/or 4G system.
In the embodiment of the invention, if the tracking area update decision request is received within the preset time before the RRC connection release message, the redirection process is forbidden, so that the user can be prevented from being redirected to the 2G pseudo base station after being inhaled into the 4G pseudo base station, the smooth communication of the user is ensured, and the user experience is improved.
