With respect to this camp-on threshold, 3GPP TS36.523-1 V6.1.2.2 specifies to verify the operation of the terminal to register with LTE (Long Term Evolution) cells.

According to the related art, a mobile station fixes a lowest radio wave reception level corresponding to a threshold value capable of camping on an LTE cell, and waits for a predetermined time in a transmission power environment of a service cell lower than a camp- It confirms that it is not registered in the corresponding service cell. Then, it is verified that the mobile terminal registers in the service cell in the transmission power environment of the service cell higher than the camp-on threshold value.

However, since the network registration operation verification process according to the related art is different from the actual user environment of the mobile communication network, it is difficult to detect various situations or problems that may occur in a real user environment in which a commercial network is operated there was. For example, since the radio reception level of the mobile terminal gradually increases when the mobile terminal enters the service area from the shaded area, according to the related art, only the case where it is lower than the camp-on threshold and the case where it is higher than the camp- It is far from the environment.

The network registration operation verifying apparatus 100 according to the embodiment includes a memory unit 110, a power control unit 120, a counter unit 130, an operation determination unit 140, and the like.

In the memory unit 110, in a heterogeneous operating environment in which a first mobile communication network and a second mobile communication network are operated together, or in a single mobile communication network, a service cell of the first mobile communication network and a service of the second mobile communication network The camp-on threshold value corresponding to the condition for registering in the cell is stored. Here, the camp-on threshold is a value indicating the transmission power of the service cell corresponding to the lowest radio wave reception level for the mobile terminal to register in the service cell of the first mobile communication network or the second mobile communication network.

The power controller 120 controls the transmission power of the service cell of the first mobile communication network or the second mobile communication network in which the mobile terminal is not registered. The transmission power is incremented by a predetermined unit starting from an initial value lower than the camp-on threshold value, and is adjusted until the mobile terminal is registered in the corresponding service cell.

The counter unit 130 counts the time required for registration of the mobile terminal from the time when the transmission power of the service cell included in the first mobile communication network or the second mobile communication network is transmitted to the initial value lower than the camp- Respectively. The counter 130 may count the registration time required for the second mobile communication network having a higher priority than that of the first mobile communication network after the mobile terminal is registered in the first mobile communication network in the heterogeneous network operating environment.

The operation determination unit 140 determines the stability of the network registration operation based on a result of comparison between the registration required time of the first mobile communication network or the second mobile communication network counted by the counter unit 130 and a predetermined reference registration time.

2 is a flowchart illustrating a network registration operation verification method according to an embodiment of the present invention.

As described above, the network registration operation verification method according to the embodiment includes a step (S201) of acquiring a threshold value corresponding to a condition that the mobile terminal registers in the service cell of the first mobile communication network or the second mobile communication network.

Thereafter, the step (S203 to S211) of counting the time required to register the mobile terminal until the mobile terminal is registered while sequentially increasing the transmission power of the service cell in which the mobile terminal is not registered from a value lower than the threshold by a predetermined unit .

After the priority of the second mobile communication network is set higher than that of the first mobile communication network, the mobile terminal sequentially increases the transmission power of the service cells not registered by the mobile terminal from a value lower than the threshold by a predetermined unit, (S213 to S219) of counting the time required for registration to be registered in the communication network.

Next, the method further includes a step (S221) of determining the registration stability according to a result of comparison between the registration required time of the first mobile communication network and the second mobile communication network and a predetermined reference registration time.

Hereinafter, a network registration operation verification process performed by the network registration operation verification apparatus according to an exemplary embodiment of the present invention will be described in detail with reference to FIG. 1 and FIG. Although the present invention can be implemented in a single operating environment of a first mobile communication network or a second mobile communication network, a case where the present invention is implemented in a mixed operating environment of a heterogeneous network will be exemplified below.

First, in the memory unit 110, in a heterogeneous operating environment in which the first mobile communication network and the second mobile communication network are operated together or in a single mobile communication network, the service cell of the first mobile communication network and the second mobile communication network The camp-on threshold value corresponding to the condition for registering in the service cell of the service area is stored.

Here, the camp-on threshold is a value indicating the transmission power of the service cell corresponding to the lowest radio wave reception level for the mobile terminal to register in the service cell of the first mobile communication network or the second mobile communication network. The camp-on threshold may be determined by a network operating device or the like and provided to a mobile terminal.

Then, the power control unit 120 reads and acquires the camp-on threshold values of the first and second mobile communication networks stored in the memory unit 110 (S201). The first and second mobile communication networks, The transmission power of the service cell is adjusted. Here, the power controller 120 first sets the transmission power of the first and second mobile communication networks to an initial value lower than the camp-on threshold (S203).

At this time, the counter 130 starts counting by driving the timer from the time when the transmission power of the service cell included in the first mobile communication network is transmitted to the initial value lower than the camp-on threshold (S205).

The power control unit 120 sequentially increases the transmission power of the first mobile communication network by a predetermined unit from an initial value lower than the camp-on threshold, and the adjustment of the transmission power is performed when the mobile station is registered in the first mobile communication network (S207).

Here, when the reception signal by the transmission power of the service cell exceeds the minimum reception level, the mobile terminal registers with the first mobile communication network (S209). At this time, (Step S211).

Next, the second mobile communication network is set to have a higher priority than the first mobile communication network by the network operating device or the like, and the counter 130 starts counting from this point by starting the timer (S213).

The power control unit 120 sequentially increases the transmission power of the second mobile communication network by a predetermined unit from an initial value lower than the camp-on threshold value, and the adjustment of the transmission power is performed by the mobile station in the second mobile communication network (S215).

Here, when the received signal by the transmission power of the service cell exceeds the lowest radio wave reception level, the mobile terminal registers with the second mobile communication network (S217). At this time, (Step S219).

Next, the operation determination unit 140 determines the stability of the network registration operation based on the comparison result between the registration required time of the first mobile communication network and the second mobile communication network counted by the counter unit 130 and the predetermined reference registration time .

Here, the reference registration time of the first mobile communication network and the reference registration time of the second mobile communication network may be set to the same value or may be set to different values. For example, the operation determination unit 140 may determine that the network registration operation is stable if the counted required registration time is earlier than the preset reference registration time (S221).

In the embodiment described above, an example of judging the registration stability of the mobile terminal after the registration required time of the first mobile communication network is acquired in step S211, and the registration required time of the second mobile communication network is acquired in step S219 Respectively. Alternatively, the registration stability of the mobile terminal for the first mobile communication network is first determined immediately after the registration time of the first mobile communication network is obtained, and then the steps S213 to S219 are performed, and the registration time of the second mobile communication network is The mobile terminal can finally determine the registration stability of the mobile terminal with respect to the second mobile communication network.

In the above-described embodiment, the registration and the acquisition of the registration time are performed once for each of the first mobile communication network and the second mobile communication network. However, the registration time can be repeatedly obtained The average value may be calculated later, and the registration stability of the mobile terminal may be determined by comparing the calculated average value with a preset reference registration time.

As described above, according to the embodiment of the present invention, after the mobile terminal is incremented in transmission power of the service cell until the mobile terminal is registered in the service cell of the mobile communication network, The stability is judged.

Since the operation of registering the mobile terminal in the service cell of the mobile communication network is verified in the state close to the actual user environment, it is easy to detect various situations or problems that may occur in the actual user environment and cope with the problem in advance.
