Specific embodiment
In order to which the purpose of the present invention, technical solution and beneficial effect is more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used to explain this hair
It is bright, it is not intended to limit the present invention.
As shown in Figure 1, the system architecture schematic diagram that the embodiment of the present invention is applicable.Arrange that multiple LTE are special along high-speed rail 101
The cell of net 102.It there also is provided multiple LTE public networks 103 on 101 periphery of high-speed rail.LTE public network 103 corresponds to core net 105.In
It include multiple terminals 104 in compartment along high-speed rail.When terminal 104 is relocated to LTE public network from LTE private network, company, terminal institute
When the TAC of the base station connect changes, terminal needs to initiate TAU request message to core net 105 corresponding to LTE public network.
Terminal in the embodiment of the present invention is that can access the terminal of LTE private network, and LTE private network is high-speed rail user in the prior art
The network accessed, therefore, the application scenarios assumed in the embodiment of the present invention are that terminal is high-speed rail user, and terminal is from LTE
Private network switches to LTE public network, so that terminal is quickly returned to LTE private network using method provided by the embodiment of the present invention at this time, below
Method provided by the embodiment of the present invention is discussed in detail.
Fig. 2 illustrates the embodiment of the present invention and provides a kind of flow diagram of blind reorientation method.
Based on system architecture shown in FIG. 1, Fig. 2 shows the embodiment of the present invention to provide a kind of blind reorientation method, including
Following steps:
Step 201, core net receives the TAU request message that terminal is sent, and the source TAC carried in TAU request message is LTE
Private network TAC；
Step 202, the base station that core net is currently resident to terminal sends TAU received message, carries in TAU received message
First instruction information, the first instruction information are used to indicate the base station that terminal is currently resident and send RRC connection release message to terminal,
And second indication information is carried in RRC connection release message, so that terminal is according to second indication information, blind to be redirected to LTE special
Net.
Specifically, the need of the terminal of the special screnes such as high-speed rail reside on LTE private network the data that just can guarantee the terminal
The transmission of normal reliable, when terminal switches to LTE public network from LTE private network, due to the TAC of TAC and the LTE public network of LTE private network
Difference, therefore terminal needs to send TAU request message to core net corresponding to LTE public network at this time, the message is for updating the end
The TAC at end.
Preferably, carrying source TAC and purpose TAC in TAU request message, the application scenarios of the embodiment of the present invention are terminal
LTE public network being switched to from LTE private network, therefore source TAC is the TAC of LTE private network, purpose TAC is the TAC of LTE public network,
And the current terminal is connected in LTE public network.
Preferably, the base station for the LTE public network that terminal is currently resident by the terminal to core net send TAU request message it
Afterwards, core net determines that source TAC is the TAC of LTE private network according to the LTE private network TAC of internal preset.Preferably, in core net
The TAC that portion presets LTE private network can be according to the preset LTE private network of core network internal after core net receives TAU request message
TAC come determine the source TAC in the TAU request message whether be LTE private network TAC, that is, judge whether the terminal is special from LTE
The base station of net switches to LTE public network base station.
Further, after core net determines that source TAC is the TAC of LTE private network, core net is currently resident to terminal
Base station send TAU received message.Specifically, the first instruction information is carried in TAU received message transmitted by core net, i.e.,
Inform the base station that the terminal is currently resident, which is that current base station, the base that terminal is currently resident are switched to from LTE private network
After station receives TAU received message, RRC connection release message is sent to terminal, though what terminal and the terminal were currently resident
Base station disconnects, and makes terminal is blind to be redirected to LTE private network by carrying second indication information in RRC connection release message.
Preferably, also carrying LTE private network frequency point information in RRC connection release message.Preferably, base station refers to according to first
Show information, obtains the LTE private network frequency point information configured on base station；The LTE private network frequency point information that base station will acquire is carried on RRC

When the base station receives TAU received message, determines that the terminal is come from the switching of LTE private network, then will configure in the base station
The frequency point of LTE private network carries in RRC connection release message, and sends to the terminal, when terminal receives the RRC Connection Release
When message, blind redirection can be executed automatically according to the LTE private network frequency point in the RRC connection release message, it is special to be switched to LTE again
In net.
Preferably, another implementation is, the frequency point of LTE private network is configured at the terminal, and in RRC connection release message
The second instruction message simply mean to show that terminal executes blind redirection, and require the terminal is blind to be redirected to LTE private network, when terminal connects
After receiving the RRC connection release message, blind redirection is executed according to the frequency point of the LTE private network configured in terminal automatically, again
It is switched in LTE private network.
Preferably, it to be to configure the frequency point of LTE private network in core net, work as core net that there is also another implementations
After receiving TAU request message, and further judge that source TAC is the TAC of LTE private network, then the core net configures inside
LTE private network frequency point and the first instruction information be carried in TAU received message, and it is currently resident to be further transmitted to terminal
Base station, the frequency point of the LTE private network is sent to terminal by RRC connection release message again by base station, so that terminal receives this
When RRC connection release message, blind redirection can be executed automatically according to the LTE private network frequency point in the RRC connection release message, again
It is switched in LTE private network.
In conclusion terminal is LTE private network user due to being LTE private network TAC as source TAC in the embodiment of the present invention,
Core net carries the first instruction information into the TAU received message that base station is sent, and base station is sent out according to the first instruction message to terminal
RRC connection release message is sent, and carries the second instruction message in RRC connection release message, terminal is according to the second instruction message
It is blind to be redirected to LTE private network, so that LTE private network user be made to switch back into LTE private network again, thus realize LTE private network user from
When LTE private network falls into LTE public network, it is switched fast back the purpose of LTE private network.
Fig. 3 illustrates the embodiment of the present invention and provides the flow diagram of another blind reorientation method.
Based on same idea, the embodiment of the present invention provides another blind reorientation method, as shown in figure 3, including following step
It is rapid:
