The present invention relates to a method for setting a user preferred network list using roaming history, and more particularly, a terminal user frequently accesses the terminal according to the edited result of the user preferred network list using the roaming history of which the terminal user has many network connections. The present invention relates to a method for setting a user preferred network list using roaming history to make terminal connection more efficient by putting a network in a local area at the priority of terminal connection.

In a mobile communication system, a wireless access network provides a user equipment with a wireless connection for mobile communication.

Each radio access network is connected to the core network, through which the user equipment is connected to the radio access network of the same mobile communication system or to components of the other mobile communication system, depending on the desired connection.

The term "user equipment" refers to Code Division Multiple Access (CDMA), CDMA2000 1x EVolution Data Only or EVolution Data Optimized (EVDO), Global System for Mobile Communications (GSM), Subscriber Identity Module (SIM) or Universal Mobile Telecommunications System (UMTS). And a subscriber identity module such as a USTS (UMTS Subscriber Identity Module).

The standard CDMA2000 1x EVDO supports a much wider bandwidth than the data service bandwidth of CDMA2000 1x.

It supports data rates up to 2.4 Mbps in the forward direction and up to 153.6 Mbps in the reverse direction.

The standard CDMA2000 1x EVDO supports the same frequency band and bandwidth as the CDMA2000 1x standard and can provide a service independently from a system supporting the CDMA2000 1x standard in the same region.

In order to use the above characteristics, a dual-mode wireless terminal using a CDMA2000 1x system and a data service using a CDMA2000 1x system and an EVDO system have emerged in an area receiving both services.

The GSM terminal executes a user authentication and encryption process on the network so that the mobile station (MS) requests registration on the network, and then, in the network, an authentication procedure for confirming whether the terminal is an authenticated terminal; It goes through an encryption process that decides whether to encrypt the data transmitted between the terminal and the network.

The system that has developed the asynchronous GSM mobile communication technology is referred to as a wide code division multiple access (WCDMA) system, which is an asynchronous next generation (3G) technology.

As such, a terminal that allows two or more mobile communication terminals that are incompatible with each other is called a dual band dual mode (DBDM) terminal.

The lower functions such as call processing in the CDMA terminal or the GSM terminal have different specs, but the upper functions such as SMS message processing have similar specifications.

Conventionally, the CDMA terminal of the DBDM terminal supports only PPP (Point-to-Point Protocol) when providing Internet service, and the UMTS of the WCDMA terminal supports IP (Internet Protocol) based on PDP (Packet Data Protocol) or PPP based on PDP. Are supported independently.

Among the user equipments, the asynchronous user terminal manually stores and edits a roaming history in which the terminal user frequently connects to the network.

In other words, the terminal user who prefers roaming to LG Telecom in editing user preference network yeast edits LG Telecom as priority 1, and the terminal user who prefers roaming of Vodafone has priority Vodafone 1 By editing the priority, the terminal user determines the priority when searching for roaming networks.

However, in the related art, since the user preference list editing is manually performed, LG Telecom, which is behind in the roaming success ranking, is ahead of the roaming priority, and LG Telecom, which is ahead of the roaming success, is inferior in the priority of the roaming. Occurs.

Therefore, when a terminal user searches for a roaming network, there is a problem that the terminal is not searched efficiently and the terminal connection with the mobile communication system is delayed.

Accordingly, the present invention has been proposed to solve the above-described problems, and the terminal network is frequently accessed by the terminal user according to the edited result of the user preferred network list using the roaming history of which the terminal user has many network connections. The purpose of the present invention is to provide a user preferred network list setting method using roaming history to make terminal connection more efficient by putting a as the priority of terminal connection.

In order to achieve the above object, the present invention provides a roaming history data display step that shows any operator network data, roaming frequency data recently connected by a terminal user, and user roaming data is automatically updated according to the roaming history graph data. And an automatic update processing step of roaming priority change which is set and edited.

The roaming history data is stored in a memory of the terminal, and the roaming priority change automatic update processing unit is stored in a SIM card of the user terminal.

The priority change automatic update may be manually updated by manual editing of the terminal user, and the manual editing update of the terminal user may be manually set using a roaming preference list option key on the menu list of the terminal.

The user roaming data automatic or manual edit update setting may be reset by the terminal user at any time according to the reset function of the user terminal.

The present invention provides a method for setting a user preferred network list using a roaming history of a terminal, wherein when roaming is performed by searching a network according to the operation of the terminal, counting and storing roaming times in a corresponding roaming network, and storing the stored data. Analyzing and determining the roaming priority and automatically updating the roaming priority when it changes.

FIG. 4 is a flowchart illustrating an overall operation flow according to a method for setting a user preferred network list using roaming history according to an embodiment of the present invention. When an operation is started, the user terminal searches for a network (401).

As a result of the user's search (401) of the network, the terminal determines whether it is roaming (402). If the user terminal does not roam, the process proceeds to the network searching (401). If the user terminal is roaming, the number of roaming counts is counted (403). Enter it.

That is, when roaming is connected to the C network, the roaming number is counted and added to the C network. If roaming is connected to the A network, the roaming count is added to the A network. If roaming is connected to the B network, the roaming is connected to the B network. The number of roaming counts is added, and if the roaming is connected to the D network, the number of roaming counts is added to the D network.

The counted number of roaming counts (403) is stored in the internal memory of the user terminal (404), and after completion of the storage (404) to analyze the total stored data (405) to determine the roaming priority (406).

The data for which the roaming priority is determined 406 is stored in the SIM card of the user terminal.

The roaming priority determination step 406 determines whether the result rank has been changed (407), if the roaming priority has not changed, maintains the current roaming priority state as it is (408), and if the roaming priority has changed, the changed roaming priority It is determined whether to update automatically (409).                     

If the result of the determination 409 is a manual update instead of an automatic update, it is displayed on the menu of the user terminal so that the terminal user can manually set the update 410 using the roaming preference list option key.

If the result of the determination 409 is an automatic update, the roaming repair order of the user roaming data stored in the SIM card is changed and updated (411).

After both the manual update 410 and the automatic update 411 process, it is determined whether there is a reset input in the user terminal (412). If there is no reset input, the process up to now is maintained and terminated. If so, all the processes up to now are reset (initialized), and then the process proceeds to the initial network search step 401.

As described in detail above, the present invention edits a user preferred network list by using a roaming history that makes a lot of network connections, and puts a network in a region frequently accessed by the terminal user as the highest priority of the terminal connection according to the edited result. As a result, when the terminal user wants to connect his terminal to the network, the mobile communication connection is quickly provided.
