Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As it is shown in figure 1, the system architecture schematic diagram that the embodiment of the present invention is suitable for.The community of multiple LTE private network 102 is arranged along the line in high ferro 101.Multiple LTE public network 103 is there also is provided at high ferro 101 periphery.LTE public network 103 is corresponding to core net 105.Multiple terminal 104 is included in the compartment that high ferro is along the line.When terminal 104 is relocated to LTE public network from LTE private network, when the TAC of the base station that terminal is connected changes, terminal needs to initiate TAU to the core net 105 corresponding to LTE public network asks message.
Terminal in the embodiment of the present invention is the terminal of accessible LTE private network, the network that in prior art, LTE private network is accessed by high ferro user, therefore, it is high ferro user that the application scenarios assumed in the embodiment of the present invention is terminal, and terminal switches to LTE public network from LTE private network, the method that now the application embodiment of the present invention is provided makes terminal quickly return LTE private network, and method that the embodiment of the present invention provided is described in detail below.
Fig. 2 illustrates the embodiment of the present invention and provides the schematic flow sheet of a kind of blind reorientation method.
Based on the system architecture shown in Fig. 1, Fig. 2 shows that the embodiment of the present invention provides a kind of blind reorientation method, comprises the following steps:
Step 201, core net receives the TAU request message that terminal sends, and the source TAC carried in TAU request message is LTE private network TAC;
Step 202, core net sends TAU to the base station that terminal is the most resident and accepts message, TAU accepts to carry the first instruction information in message, first instruction information sends RRC connection release message for the base station indicating terminal the most resident to terminal, and carry the second instruction information in RRC connection release message, so that terminal is redirected to LTE private network according to the second instruction information is blind.
Specifically, the need of the terminal of the special screnes such as high ferro reside in the transmission of the data normal reliable of this terminal of guarantee on LTE private network, when terminal switches to LTE public network from LTE private network, owing to the TAC of TAC from the LTE public network of LTE private network is different, therefore terminal now needs to send TAU to the core net corresponding to LTE public network and asks message, and this message is for updating the TAC of this terminal.
