At the beginning of the operation of a mobile terminal 1 to be tested, link establishment means 211 performs a process of establishing a link to the mobile terminal 1. When the link is established, test mode change means 213 transmits a message “downlink Direct Transfer (Activate RB Test Mode)” for setting test mode connection from a base station, returns a response message to a message transmitted from the mobile terminal 1 to be tested, thereby changing the mobile terminal 1 to be tested to a test mode, and performs a transmission and reception test. A mobile terminal test device for testing a mobile terminal which transmits and receives a signal to and from a base station to perform a link establishment process and a location registration process at the beginning of an operation when power is turned on or a reset operation is performed, changes to an idle state after a link is opened, performs the link establishment process again in response to a connection request from the base station in the idle state, and performs communication through the base station, comprising. A mobile terminal test method for testing a mobile terminal which transmits and receives a signal to and from a base station to perform a link establishment process and a location registration process at the beginning of an operation when power is turned on or a reset operation is performed, changes to an idle state after a link is opened, performs the link establishment process again in response to a connection request from the base station in the idle state, and performs communication through the base station, comprising. In a mobile terminal communication system, a mobile terminal in the service area of the base station receives radio waves from the base station when it is turned on or it is reset, transmits a request to the base station that communication therebetween can be performed, and changes to a state in which it can communicate with the base station (link established state). Then, the mobile terminal notifies the base station of its unique information and performs an authentication and location registration process for registering the existence area of the mobile terminal to the network including the base station. Then, the mobile terminal performs a link open process and changes to an idle state. Then, when communication, such as call connection (the reception of a call) or call transmission from the base station, is needed, the mobile terminal changes to a communication state with the base station. That is, at the beginning of the operation, a mobile terminal 1 transmits a message Mu1=rrc Connection Request (establishment Cause: registration) for requesting communication with the base station in order to register the location. A test device 10 transmits a message Md1=rrc Connection Setup for designating, for example, a channel used for communication with the mobile terminal 1, in response to the request. Hereinafter, Mu (number) is referred to as a message transmitted by the mobile terminal 1 and Md (number) is referred to as a message transmitted by the test device (pseudo-base station apparatus) 10. That is, the test device 10 transmits a message Md2=downlink Direct Transfer (Authentication and ciphering request) indicating the value of a random number (RAND) which is used in the authentication calculation of the mobile terminal 1. When receiving the message, the mobile terminal 1 performs a predetermined operation using the RAND value and its own information, inserts the calculation result into a message Mu4=uplink Direct Transfer (Authentication and ciphering response), and returns the message. Then, the test device 10 transmits a message Md4=downlink Direct Transfer (Identity request: IMSI) for inquiring about a user identification number IMSI (International Mobile Subscriber Identity) which is allocated to each user of the mobile terminal. The mobile terminal 1 returns a response message Mu6=uplink Direct Transfer (Identity response). In addition, the IMSI and key information (Authentication key) unique to the user which is used for authentication are stored in a SIM of the mobile terminal.

So I have some users which I have on either 'test' recurring charge and some on 'trial'. How can I 'force' them to accept the new plan (change of the name of the plan. Example from the app sample on github (https://github.com/Shopify/example-ruby-app/blob/master/02%20Charging%20For%20Your%20App/app.rb). Field Test Mode: What it is and How To Enable it on Your Phone. One of the first steps to selecting a cell phone signal booster for your home or office, vehicle,. The exchange of the messages Md8 to Mu12 is a link re-establishment process for a test. After the link establishment is completed, the test device 10 transmits a message Md10=downlink Direct Transfer (Authentication and ciphering request) indicating a RAND value which is used for authentication calculation in order to authenticate the mobile terminal 1. When receiving the message, the mobile terminal 1 performs predetermined calculation using authentication key information (Authentication key) and the RAND value and returns a message Mu13=uplink Direct Transfer (Authentication and ciphering response) including the calculation result. As such, the test device according to the prior art changes the mobile terminal to the state in which the mobile terminal can be tested by the same process as the communication process between the base station and the mobile terminal and then tests the mobile terminal. In recent years, the processing speed and function of the mobile terminal have increased and a multi-band mobile terminal has been developed. As a result, the test time increases due to an increase in the number of test items. When the mobile terminals are tested one by one in a manufacturing line, there is a strong demand for a technique capable of effectively performing the test. In addition, as shown in the chart of FIG. 4, after the location registration process, the link is opened and the mobile terminal enters the idle state. Then, the link is re-established and the mobile terminal changes to the test mode. Therefore, even though the location registration process is omitted as in the above-mentioned Patent Document 1, it takes a considerable amount of time until the test is performed and it is difficult to effectively test the mobile terminal during a manufacturing process. In the test, it is necessary to use a test SIM whose stored information is known in order to authenticate the mobile terminal. However, there is a strong demand for a test in the state in which the actual SIM (Subscriber Identity Module) which stores information for specifying user information, such as the phone number of the mobile terminal is mounted, in order to check the operation of an M2M module before shipment. Since the parameters stored in the actual SIM are unknown, failure occurs in the test. In particular, when IMSI, which is the unique value of the SIM, or key information (Authentication key) used for authentication is unclear, the unclear IMSI or key information has a great effect on the test. For example, when being connected to the mobile terminal in the idle state, the base station transmits a paging to the mobile terminal. However, the mobile terminal in the idle state intermittently receives the paging only at the time calculated from the IMSI. Therefore, the base station acquires the IMSI stored in the SIM of the mobile terminal and performs authentication with reference to the calculation result using the key information stored in the SIM. Therefore, the test device needs to re-establish the link (call connection) using the authentication process according to the above-mentioned sequence and it is difficult to test the mobile terminal provided with the actual SIM whose stored content is unknown. According to a second aspect of the invention, the mobile terminal test device according to the first aspect may further include pseudo-authentication means ( 212) for exchanging a message related to authentication with the mobile terminal when the link establishment means establishes the link to the mobile terminal. When the pseudo-authentication means completes the exchange of the message related to the authentication, the test mode change means may transmit the message “downlink Direct Transfer (Activate RB Test Mode)” for setting test mode connection from the base station to the mobile terminal. According to a third aspect of the invention, there is provided a mobile terminal test method for testing a mobile terminal which transmits and receives a signal to and from a base station to perform a link establishment process and a location registration process at the beginning of an operation when power is turned on or a reset operation is performed, changes to an idle state after a link is opened, performs the link establishment process again in response to a connection request from the base station in the idle state, and performs communication through the base station. The mobile terminal test method includes a step of exchanging a message required for the link establishment with the mobile terminal at the beginning of the operation, a step of performing a transmission and reception test for the mobile terminal, and a step of transmitting a message “downlink Direct Transfer (Activate RB Test Mode)” for setting test mode connection from the base station to the mobile terminal when the link to the mobile terminal is established and making the mobile terminal return a response message to the message, thereby changing the mobile terminal to a test mode. In the step of performing the transmission and reception test, the transmission and reception test is performed for the mobile terminal which is changed to the test mode. According to a fourth aspect of the invention, the mobile terminal test method according to the third aspect may further include a step of exchanging a message related to authentication with the mobile terminal when the link to the mobile terminal is established. When the exchange of the message related to the authentication is completed, the message “downlink Direct Transfer (Activate RB Test Mode)” for setting test mode connection from the base station may be transmitted to the mobile terminal. Advantage of the Invention•. As such, in the invention, at the beginning of the operation of the mobile terminal to be tested, a process for establishing a link to the mobile terminal is performed. When the link is established, the test device transmits a message “downlink Direct Transfer (Activate RB Test Mode)” for setting test mode connection from the base station and returns a response message to the message which is transmitted from the mobile terminal to be tested, thereby changing the mobile terminal to be tested to the test mode. Then, the transmission and reception test is performed for the mobile terminal. The pseudo-authentication means 212 is used when it is difficult for the mobile terminal 1 to be tested to change to the test mode because the mobile terminal 1 does not pass an authentication process for information stored in a SIM and exchanges the message required for the authentication with the mobile terminal 1. However, the pseudo-authentication means 212 does not perform a determination process required for the actual data matching and transmits an authentication completion message in response to the information notified by the mobile terminal 1, without any conditions (pseudo-authentication). When the link establishment is completed and the exchange of the message for the pseudo-authentication process is completed, the test mode change means 213 transmits a message “downlink Direct Transfer (Activate RB Test Mode)” for setting test mode connection from a base station and changes the mobile terminal 1 to be tested to the test mode. The change is premised on flexibility in the response of the mobile terminal to the transmitted message. In recent years, various mobile terminals have been manufactured which can exactly respond to the message transmitted from the base station in the unexpected mode and change to the test mode, with a link to the base station being established. The test device 20 according to this embodiment tests this type of mobile terminal 1. The process from Mu1 to Mu2 is a link establishment process and Mu3 is a connection request process. However, here, it is assumed that a link is established after Mu1 to Mu3 are performed. After the establishment of the link is completed, a message Md2 (=Md10)=downlink Direct Transfer (Authentication and ciphering request) which indicates a RAND value used in authentication calculation is transmitted for the pseudo-authentication of the mobile terminal 1. When receiving the message, the mobile terminal 1 returns a message Mu4 (=Mu13)=uplink Direct Transfer (Authentication and ciphering response) for transmitting the calculation result. The pseudo-authentication of the mobile terminal 1 to be tested is performed by the exchange of the messages Md2 to Mu5. When the authentication ends, the test device proceeds to a message exchange process for location registration in the prior art. However, in this embodiment, when the authentication ends, the test device transmits a message Md12=downlink Direct Transfer (Activate RB Test Mode) for setting test mode connection to the mobile terminal 1. The mobile terminal 1 returns a response message Mu15=uplink Direct Transfer (Activate RB Test Mode Complete). 3 is a chart illustrating the operation of the test device 20 when the mobile terminal which can omit SIM authentication is tested. In the chart, the exchange of the messages Md2, Md3, Mu4, and Mu5 for pseudo-authentication in the chart shown in FIG. 2 is omitted. When the link establishment process from Mu1 to Mu3 is completed at the beginning of the operation, the test device immediately transmits the message Md12=downlink Direct Transfer (Activate RB Test Mode) for setting test mode connection to the mobile terminal 1 to change the mobile terminal 1 to the test mode, without performing the pseudo-authentication process. Then, the mobile terminal 1 is tested by the same process as that in FIG. The user can perform a mode designation operation using an operation unit (not shown) to arbitrarily designate one of the two test modes. In addition to the two simplified test modes, the test mode (third test mode) according to the prior art shown in FIG. 4 can be executed. It is possible to designate any one of the first to third test modes according to flexibility in the mode change of the mobile terminal to be tested by the messages. According to this structure, it is possible to respond to mobile terminals manufactured by many different manufacturers. In addition, it is possible to achieve a test device which can respond to multiple types of apparatuses with different functions manufactured by the same manufacturer and has high compatibility.
