Referring to FIG. 5, the OTA server 500 sets a PLMN value indicating a radio access technology (RAT) of the terminal 600. To this end, the OTA server 500 may collect information about the terminal 600. The information about the terminal 600 may be a model of the terminal 600, a rate plan selected by a user of the terminal 600, and the like.

The OTA server 500 transmits the set PLMN value to the terminal 600 through the OTA. In this case, at least one of an SMS scheme, an MMS scheme, and an OMA-DM scheme may be used.

The terminal 600 receives the PLMN value from the OTA server 500 and stores the received PLMN value in the USIM 700. Up to 20 PLMN values may be stored in the USIM 700. The terminal 600 retrieves a list of PLMN values stored in the USIM 700. When the PLMN value corresponding to the predetermined wireless access method is found, the terminal 600 performs network access according to the corresponding wireless access method.

Hereinafter, a network access control method between the OTA server 500 and the terminal 600 will be described in more detail.

A flowchart illustrating a network access control method.

Referring to FIG. 6, the OTA server 500 includes a terminal information collecting unit 510, a control information setting unit 520, and a transceiver unit 530.

The terminal information collecting unit 510 collects terminal information. The terminal information may be information about a model of the terminal, information about a plan selected by the user of the terminal, and the like. The terminal information collecting unit 510 may collect terminal information from a carrier server or a provider server.

The control information setting unit 520 sets control information indicating a wireless access method of the terminal based on the terminal information. Control information indicating a wireless access method of the terminal may be set to a PLMN value.

The transceiver 530 transmits the set control information to the terminal through the OTA. The OTA may be, for example, at least one of an SMS scheme, an MMS scheme, and an OMA-DM scheme.

Referring to FIG. 7, the terminal 600 includes a processor 610, a memory 620, and a radio frequency (RF) unit 630. The processor 610 may be configured to implement the procedures and / or methods proposed in the present invention. The memory 620 is connected to the processor 610 and stores various information related to the operation of the processor 610. The RF unit 630 is connected with the processor 610 and transmits and / or receives a radio signal.

The processor 610 selects a wireless access method of the terminal according to the PLMN value received from the OTA server 500 through the OTA, and performs a network connection according to the selected wireless access method.

The terminal 600 is connected to the USIM 700. Up to 20 PLMN values may be stored in the USIM 700. 9 is an example of a list 900 of PLMN values stored in the USIM 700. As illustrated in FIG. 9, at least one Home PLMN 910, at least one User PLMN 920, and at least one Operator PLMN 930 may be stored in the USIM 700. The Home PLMN 910 is a PLMN value basically set for each USIM and is an International Mobile Subscriber Identity (IMSI). User PLMN 920 is a PLMN value set by a user. The operator PLMN 930 is a PLMN value set by a communication company. The PLMN value received through the OTA from the OTA server 500 may be stored in the operator PLMN 930.

6 to 8, the control information setting unit 520 of the OTA server 500 sets a PLMN value indicating a wireless access method of the terminal 600 (S800). In this case, the wireless access method may include, for example, a method in which the terminal 600 preferentially accesses a WCDMA network, a method in which the terminal 600 preferentially accesses an LTE network, and a terminal 600 in an idle mode. ), It may be one of the methods to stay in the WCDMA network and move to the LTE network for the data call. The wireless access method of the terminal 600 may be previously selected by the user.

The PLMN value may be set to a value other than a previously defined value in order to identify the network of the operator. The PLMN value and the corresponding wireless access method may be previously promised between the OTA server 500 and the terminal 600. For example, when the PLMN value is 45011 (MCC = 450, MNC = 11), the terminal 600 is set to preferentially access the WDCMA network, and the PLMN value is 45012 (MCC = 450, MNC = 12). If the terminal 600 is set to preferentially access the LTE network, and the PLMN value is 45013 (MCC = 450, MNC = 13), the terminal 600 stays in the WCDMA network if the terminal 600 is in the idle mode. It may be set to move to the LTE network.

The transceiver 530 of the OTA server 500 transmits a PLMN value to the terminal 600 through the OTA (S810). Here, the OTA may be at least one of an SMS method, an MMS method, and an OMA-DM method.

The terminal 600 stores the PLMN value received from the OTA server 500 in the USIM 700 (S820). The PLMN value received from the OTA server 500 may be stored as the operator PLMN 930.

The terminal 600 selects a wireless access method of the terminal according to the PLMN value stored in the USIM 700 (S830). For example, if 45011 is in the list of PLMN values stored in the USIM 700, the terminal 600 may select a method of preferentially accessing the WDCMA network. If 45012 is in the list of PLMN values stored in the USIM 700, the terminal 600 may select a method of preferentially accessing the LTE network. When 45013 is in the list of PLMN values stored in the USIM 700, the terminal 600 may stay in the WCDMA network when in the idle mode, and select a method of moving to the LTE network for the data call. At this time, the voice call can be serviced through the WCDMA network. To this end, the terminal 600 searches whether there is a PLMN value corresponding to a predetermined wireless access method among at least one PLMN value stored in the USIM 700, and when a PLMN value corresponding to the predetermined wireless access method is found, The wireless connection method can be selected. For example, the terminal 600 searches for the 45012 corresponding to the method of preferentially accessing the LTE network among the PLMN values stored in the USIM 700, and wirelessly accesses the LTE network preferentially when the 45012 is found. You can choose the method.

In addition, the terminal 600 performs network access according to the selected wireless access method (S840).

As such, according to an embodiment of the present invention, the network access method of the terminal can be controlled through the OTA. In particular, even if the terminal supports both the LTE technology and the WCDMA technology, it is possible to set up a network to which the terminal user can preferentially access according to the plan selected by the user. In addition, by using a PLMN value that is not used previously, it is possible to increase the efficiency of the resource.

The embodiments of the present invention described above are not implemented only by the apparatus and method, but may be implemented through a program for realizing the function corresponding to the configuration of the embodiment of the present invention or a recording medium on which the program is recorded.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It belongs to the scope of right.
