Description
The present invention relates to a method of operating a localization service of a mobile communication terminal, and more particularly, a localized service that can reduce excessive load of a system and reduce sudden current consumption of a mobile communication terminal by preventing excessive repetition of location registration. It is about how to manage localization service information required for.
In a mobile communication network, there are standards (eg, 3GPP TS 23.073) that provide localized service within a specific region. In addition, mobile operators have provided various services to these localization services. For example, localization service provided by domestic mobile service providers in the name of 'free-zone' may be charged when users' mobile communication terminals are located in a predetermined area for users who subscribed to the service in advance. This is to take a differentiated policy, including other services and limitations on the functions of mobile communication terminals.
Specific areas may include university campuses or businesses of specific businesses, and localized services may block the functions of the built-in cameras mounted on mobile communication terminals in university campuses, industrial complexes and research institutes of specific universities, This means restricting the dial-up networking function, the outgoing video call function, or configuring various charge policies. For example, in order to solve security problems in corporate factories and research complexes, certain areas such as cameras and dial-up adapters attached to mobile communication terminals may be restricted, and voice calls may be charged at low cost. It is a service related to service policy such as restricting advanced functions such as video call.
In this case, information about a service that is allowed or not allowed in a specific region is transmitted through several bits of an LSA ID in a GSM Mobility Management (GMM) information message according to the 3GPP standard. For example, the upper five bits of the LSA determine whether to allow or block (On / Off) the camera function, the dial-up network function, the video call transmission function, and the service menu setting function of the terminal. That is, when a terminal subscribed to a localization service enters a localization service area, after receiving location registration, the terminal finally receives a GMM information message and receives a service that is allowed and disallowed through some bits of the LSA ID in the GMM information message. As a result, the function of the mobile communication terminal is restricted or terminated.
When the mobile terminal subscribed to the localization service is powered on in the localized service cell or enters the localized service cell from a cell other than the localized service cell, the mobile terminal checks whether the mobile terminal exists in the localized service area. Location registration will be performed to receive service details. Similarly, when the localized service area leaves the public area, location registration is performed and GMM information message is received from the mobile communication network to update the localized service content to a normal state. Accordingly, the mobile communication terminal subscribed to the localization service repeats a routing area updating procedure when entering and leaving the localization service area to receive localization service information. This location registration process can put a heavy load on the system due to the message transmission and processing process between the terminal and the mobile communication network, and also dramatically increases the battery consumption of the mobile communication terminal.
In particular, in the boundary area where the public network and the localized service area are adjacent to each other, the location registration process may be repeatedly performed, resulting in unstable operation of the mobile communication terminal, and it may cause a problem in operating the system of the mobile communication network due to overflow. .
An object of the present invention for solving the above problems, the mobile communication terminal of the mobile communication terminal that can reduce the repeated location registration process when the mobile communication terminal subscribed to the localized service area or entering the localized service area. It is to provide a localization service information management method.
According to an aspect of the present invention, there is provided a method for managing localization service information of a mobile communication terminal, the method comprising: receiving a service group ID, a service ID, and a localized service value from a currently connected cell in a mobile communication network; A localization service determining step of reading a service group ID and a localized service ID and comparing the service group ID and a service ID and if the stored localized service group ID and localized service ID and the received service group ID and service ID are the same, Determining that the currently connected cell is a localization service cell, and setting a localization service function using the received localization service value to establish a function of a mobile communication terminal; There is provided a method.
Here, in the step of receiving localized service information, the localized service group ID, localized service ID, and localized service value are configured to be transmitted through a System Information Block (SIB) message when the mobile communication terminal is in an idle state. When the mobile communication terminal is connected, the mobile communication terminal may be configured to be delivered through an active set update message.
Here, in the localization service determination step, the stored localization service group ID and localization service ID may be stored in a nonvolatile memory inside the mobile communication terminal, or may be stored in a user identification module (SIM) card mounted in the mobile communication terminal. Can be.
Here, the value of the localization service is whether the function of the camera mounted on the mobile communication terminal in the currently connected cell is limited, whether or not the function of the dial-up adapter of the mobile communication terminal and the video call transmission function of the mobile communication terminal is limited. It may include.
Herein, the mobile communication terminal that has passed the localization service function setting step includes a predetermined indication value in the voice call or video call setup message when the voice call or the video call is transmitted in the corresponding localization service area. It indicates that the voice or video call is originated in the localization service, and when a data service request is made in the corresponding localization service area, the voice of the localization service is included in the mobile communication network by including a predetermined indication value in the PDP context activation request message. Or it may be configured to inform that the video call origination.
In this case, the predetermined indication value may preferably be configured to include the stored localized service group ID and localized service ID.
When using the method for managing localization service information of a mobile communication terminal according to the present invention as described above, location registration performed by a mobile communication terminal subscribed to a localization service to download localization service control information from a mobile communication network can be prevented.
In particular, when a mobile communication terminal subscribed to a localization service repeatedly enters and exits a localization service cell and a cell other than the localization service cell, it is possible to prevent a problem according to the prior art that the location registration is excessively repeated. Through this, it is possible to prevent the rapid consumption of the battery due to the repeated location registration and reduce the load on the mobile communication network.

Hereinafter, each step of configuring the localization service information management method of the mobile communication terminal according to the present invention will be described in detail step by step.
1) Service Information Receiving Step
The service information receiving step (S110) is a step of receiving a service group ID, a service ID, and a localized service value from a cell to which a mobile communication terminal existing in the mobile communication network is currently connected.
In this case, the mobile communication network refers to the second and third generation mobile communication networks. An embodiment of a method for receiving localization service information of a mobile communication terminal according to the present invention described with reference to FIG. 1 will be described based on the standard (3GPP) of Wide-band Code Division Multiple Access (WCDMA) among 3G mobile communication networks. In the case of mobile communication networks conforming to other standards, the same may be described through corresponding components.

In addition, when the
2B is a diagram illustrating a configuration example of a service group ID, a service ID, and a localized service value in a method for managing localization service information of a mobile communication terminal according to the present invention.
Herein, it is described that the
Referring to FIG. 2B, the
For example, an example of an additional service that a mobile communication terminal can subscribe to is a 'two-phone' service that can use two phone numbers in one terminal, a localized service that is the subject of the present invention, and the like. Can be mentioned. In this case, a service group ID '3' may be assigned to the 'two phone' service mentioned above, and a service group ID '4' may be assigned to the localized service mentioned later.
Next, the
Apart from the service group ID that designates the additional service supported by the cell, the reason for specifying the service ID is that the additional service supported by the specific cell should be applied only to specific terminals and restricted to other terminals. Because there may be.
For example, assuming that the additional service corresponds to a localized service that is the object of the present invention, a mobile communication terminal subscribed to a localization service applied only within the university campus may be located in another B. This is because it is necessary to restrict the use of localization services on the company premises.
Meanwhile, the role of the above-described service group ID and service ID will be described later with reference to FIG. 3.
Finally, the localization service value 253 may be determined by the number of configuration bits corresponding to the function of the mobile communication terminal to control whether or not to limit the function, whether the localization service value is limited to the function of the camera mounted on the mobile communication terminal, telephone access When the adapter function is limited, the video call originating function is limited, or the localization service function is set, and the like may be configured as a bit string of 4 to 5 bits. That is, the localization service value 253 is to replace the role of the Localized Service Area (LSA) ID in the GMM / MM information message finally received after location registration, as described in the prior art. In FIG. 2B, it is assumed that the localization service value 253 is composed of 5 bits to control whether or not the function is restricted for five functions existing in the mobile communication terminal.
In addition, the number of bits constituting the
2) Localization Service Determination Step
Localization service determination step (S120) is a step of comparing the received service group ID and service ID by reading the stored localization service group ID and localization service ID.
That is, the localization service determination step (S120) is a step of determining whether the mobile communication terminal is the application target of the localization service in the cell that is currently connected.
The stored localization service group ID and the localization service ID may be downloaded to the user's terminal by using an over-the-air (OTA) message when the user of the corresponding mobile communication terminal subscribes to the localization service.
The localization service group ID and the localization service ID may be stored in a nonvolatile memory (NV memory) provided inside the mobile communication terminal, and stored in a universal subscriber identity module (USIM) mounted separately in the mobile communication terminal. May be
As mentioned above, the received service group ID is compared with the stored localized service group ID, and the received service ID is compared with the stored localized service ID to determine whether the mobile communication terminal is applicable to the localized service in the currently connected cell. The concept of determining the will be described later with reference to FIG.

3) Localization service function setting step
Finally, the localization service function setting step (S130) determines that the currently connected cell is a localization service cell when the stored localization service group ID and localization service ID and the received service group ID and service ID are the same. It is a step of setting a function of the mobile communication terminal using the localized service value.
As mentioned above, the value of the localization service may be configured to include whether the camera mounted on the mobile communication terminal is limited, whether the dial-up adapter is restricted, whether the video call is restricted, and whether the localized service is set. For example, depending on the localization service, the functions of which functions are restricted may be configured differently.
On the other hand, the mobile communication terminal to which the localization service is applied by the localization service function setting step (S130) as described above during the localization service when an audio call or a video call is sent or a data service is requested. It is necessary to inform the mobile communication network that the voice call, video call, and data service from the mobile communication terminal.
That is, in the case of voice call, video call, and data service from the mobile communication terminal in the localization service, the billing system may be changed according to the service policy of the subscribed localization service.
Therefore, the mobile communication terminal needs to notify the mobile communication network that the voice call, video call or data service is in the localized service state when sending a voice call or a video call or requesting a data service.
For example, when the mobile communication terminal in the localization service transmits a voice call or a video call, the mobile communication terminal may be configured to include a predetermined indication value in the voice call or video call setup message and transmit it to the MSC (Mobile Switching Center). have. When a mobile communication terminal requesting a data service requests a data service, the mobile communication terminal includes a predetermined indication value in a PDP context activation request message and transmits it to a Serving GPRS Support Node (SGSN). Can be configured.
In this case, as the predetermined indication value, preferably, the service group ID and the service ID stored in the mobile communication terminal may be included and transmitted. The MSC or SGSN, having received the predetermined indication value by the above-described method, transmits the information to the Core Network (CN) entity that controls the billing server or the corresponding supplementary service (localization service) to service the service provider. Follow the policy.
In the above description, a preferred embodiment of the present invention has been described based on terms based on 3GPP standards that define third generation or more mobile communication services such as Wideband Code Division Multiple Access (WCDMA). It will be understood that various modifications and changes can be made in the present invention without departing from the spirit and scope of the invention as set forth in the claims.
