Problems solved by technology

If the user's mobile phone signal is forced to connect to the pseudo base station device, the mobile phone will not be able to use the services provided by the operator normally. Generally, it will return to normal after being temporarily disconnected from the network for 8 to 12 seconds. Some mobile phones must be switched on and off to restart. Access to the network has a very bad impact on user experience

Embodiment 1

[0066] Such as figure 1 As shown, the redirection method in Embodiment 1 of the present invention is applied to a base station, including:

[0067] Step 101, performing a random access procedure with a terminal.

[0068] In practical applications, each base station sends a system broadcast message to the terminal. The terminal detects the signal strength of each base station based on the received system broadcast message, and selects a base station with better signal strength for random access and cell reselection.

[0069] Step 102, performing an RRC connection process with the terminal.

[0070] 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 settings. After completion, the terminal sends an RRC connection setup complete message to the base station.

[0071] Step 103, receiving a tracking area updat...

Embodiment 2

[0081] Such as figure 2 As shown, the redirection method in Embodiment 2 of the present invention is applied to a terminal, including:

[0082] Step 201, performing a random access procedure with a base station.

[0083] In practical applications, each base station sends a system broadcast message to the terminal. The terminal detects the signal strength of each base station based on the received system broadcast message, and selects a base station with better signal strength for random access and cell reselection.

[0084] Step 202, perform an RRC connection process with the base station.

[0085] 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 settings. After completion, the terminal sends an RRC connection setup complete message to the base station.

[0086] Step 203: Send a tracking area update r...

Embodiment 3

[0095] Such as image 3 As shown, the redirection method in Embodiment 3 of the present invention is applied to a terminal, including:

[0096] Step 301, receiving an RRC connection release message sent by a base station.

[0097] Step 302. Determine whether a tracking area update rejection request has been received within a predetermined time before receiving the RRC connection release message.

[0098] Wherein, the predetermined time may be 3 ms or the like.

[0099] Step 303: If the tracking area update rejection request has been received, re-access the neighboring cell of the current serving cell in a different system; if the tracking area update rejection request has not been received, perform redirection according to the redirection information.

[0100] For example, if the tracking area update rejection request is received, redirection to the 2G system is not performed, and the 4G neighboring cell of the current serving cell is re-accessed.

[0101] In practical appl...

Abstract

The present invention provides a redirection method and device, which relate to the technical field of communications, and are used to prevent users from being redirected to pseudo base stations and improve user experience. The redirection method of the present invention includes: performing a random access process with the terminal; performing a radio resource control RRC connection process with the terminal; receiving a tracking area update request sent by the terminal; sending a tracking area update rejection request to the terminal ; Send a radio resource control RRC connection release message to the terminal; wherein, the RRC connection release message does not carry information for redirection; or, the RRC connection release message carries the information of the different system of the 2G system frequency point information; or, the RRC connection release message carries 2G frequency point information and frequency point information of a different system of the 2G system, and the priority of the 2G frequency point is lower than that of the frequency point of the different system Point priority. The present invention is mainly used in redirection technology.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a redirection method and device. Background technique [0002] Recently, some pseudo base stations have been found in the live network, including 4G pseudo base stations and 2G pseudo base stations. Pseudo base stations attract users through high-power signals. If the user's mobile phone signal is forced to connect to the pseudo base station device, the mobile phone will not be able to use the services provided by the operator normally. Generally, it will return to normal after being temporarily disconnected from the network for 8 to 12 seconds. Some mobile phones must be switched on and off to restart. Access to the network has a very bad impact on user experience. Contents of the invention [0003] In view of this, the present invention provides a redirection method and device to prevent users from being redirected to pseudo base stations and improve user e...
