Description

Service network selection method of terminal in IPv6/IPv4 dual network, and apparatus and system therefor}

The present invention relates to an IPv6/IPv4 dual network communication technology, and more particularly, to a technology for a terminal equipped with an IPv6/IPv4 dual stack to select a service network in an IPv6/IPv4 dual network.

The Internet is positioned as the core infrastructure of the information society, and due to the development of real-time, high-quality services such as VoIP (Voice of IP) and Internet TV, the traffic exchanged through the Internet is also reduced to traffic containing text information. It is changing to multimedia traffic including voice information, image information, and video information, and the amount of traffic is explosively increasing.

The currently built IPv4 (Internet Protocol Version 4)-based Internet uses small address information and a complex header structure to accommodate rapidly increasing host and multimedia traffic, which slows down the processing speed of routers and nodes that process traffic. It is delayed, and there is a problem of degrading the performance of the entire Internet.

IPv6 (Internet Protocol Version 6) proposed to solve the problems of the IPv4-based Internet has features such as a 128-bit extended address system, a simplified header structure, improved QoS (Quality of Service) and enhanced security. Have.

However, since the current Internet is constructed and widely operated as an IPv4 network, it is practically impossible to switch to an IPv6 network instantly. For the time being, it is expected that the IPv4 network and the IPv6 network will coexist and gradually switch to the IPv6 network.

Therefore, a server supporting IPv4 and a server supporting IPv6 can be simultaneously operated, and a terminal can receive a service by selecting one of these service providing servers or accessing both service providing servers at the same time to receive a service. can

In general, high-end terminals using a Window-based operating system (OS) and an Android-based OS are equipped with an IPv6/IPv4 dual stack, and the terminal itself can operate both stacks simultaneously and provide IPv6 service. The service may be provided by selectively accessing any one of the server and the IPv4 service providing server.

However, in the case of a low-end terminal based on an embedded OS, although it has an IPv6/IPv4 dual stack, since both stacks cannot be operated simultaneously, only one stack can be selectively operated at a specific time. That is, since only one stack is driven at the time of initial opening or booting/rebooting of the terminal, there is a problem in that the probability of network connection failure increases and the booting speed slows down.

If a terminal has an IPv6 IP address and a service providing server for a specific service operates only with the IPv4 IP address system, the corresponding terminal cannot receive the specific service. Conversely, even when a terminal has an IPv4 IP address and a service providing server for a specific service operates only with the IPv6 IP address system, the corresponding terminal cannot normally receive the specific service.

Therefore, an effective network access technology for low-end dual-stack terminals that cannot simultaneously operate both IPv4 and IPv6 stacks is required.

An object of the present invention is to provide a method for selecting a service network of a terminal in an IPv6/IPv4 dual network, and an apparatus and system therefor.

Another object of the present invention is to provide a method and apparatus for efficiently selecting a service network for a low-end terminal that cannot simultaneously operate both IPv4 and IPv6 stacks in an IPv6/IPv4 dual network environment.

Another object of the present invention is to provide a service network selection method and apparatus and system for enabling a terminal and a service providing server to maintain the same IP scheme in an IPv6/IPv4 dual network environment.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 7 .

1 is a diagram for explaining a server configuration and an operation of a terminal in a conventional IPv4 network.

Referring to FIG. 1 , a server constituting an IPv4 network may include a dynamic host configuration protocol (DHCP) server, an IPv4 provisioning server, and an IPv4 service providing server.

The DHCP server performs a function of dynamically allocating IP address information (or network information) to hosts within an address block allocated from an Internet Service Provider (ISP). Here, the network information may include IP address information, subnetmask information, gateway information, domain name server (DNS) information, and the like. The terminal can automatically connect to the DHCP server to request and obtain network information without a separate setting.

The IPv4 provisioning server is an operating server managed by a service provider to provide IPv4 service. It is an IPv4 Auto Provisioning Server (APS) that provides various information for service provision and various setting values for service provision. It may be configured to include an IPv4 Auto Configuration Server (ACS) and an IPv4 Image Download Server (IDS) providing information for firmware upgrade.

The IPv4 service providing server may provide a specific service (or content) requested by a terminal through an IPv4 network.

Conventional IPv4 networks could provide only IPv4-based services to terminals having an IPv4 stack.

2 is a diagram for explaining a server configuration and a terminal operation in an IPv6/IPv4 dual network system according to an embodiment.

An IPv6/IPv4 dual network can be composed of servers operated based on IPv6 and servers operated based on IPv4.

If a terminal has an IPv6 IP address and a service server to which the terminal is connected operates based on an IPv4 IP address, the terminal cannot receive service from the corresponding service server. Conversely, even when a terminal has an IPv4 IP address and a service server to which the terminal is connected operates based on the IPv6 IP address, the terminal cannot receive service from the corresponding service server.

Therefore, it is important that the terminal and the service server maintain the same IP scheme in order for the terminal to receive normal service in the IPv6/IPv4 dual network environment.

Referring to FIG. 2, servers constituting the IPv6/IPv4 dual network are largely a dynamic host configuration protocol server (DHCP (Dynamic Host Configuration Protocol) Server), IPv4 provisioning server, IPv6 provisioning server, IPv4 service providing server (or IPv4 service server). ) and IPv6 service providing server (or IPv6 service server).

The DHCP server performs a function of dynamically allocating IP address information (or network information) to hosts within an address block allocated from an Internet Service Provider (ISP). Here, the network information may include IP address information, subnetmask information, gateway information, domain name server (DNS) information, and the like. The terminal can automatically connect to the DHCP server to request and obtain network information without a separate setting.

The DHCP server may allocate an IPv4 address or an IPv6 address according to the terminal's IP allocation request.

The IPv4 provisioning server is an operation server managed by a service provider to provide IPv4 service. It is an IPv4-dedicated Auto Provisioning Server (APS) that provides various information for providing IPv4 service, and various setting values for providing IPv4 service. It may be configured to include an IPv4-only Auto Configuration Server (ACS) that provides IPv4-only Auto Configuration Server (ACS) and an IPv4-only Image Download Server (IDS) that provides IPv4-related firmware upgrade information.

The IPv6 provisioning server is an operation server managed by a service provider to provide IPv6 service. It is an IPv6-dedicated Auto Provisioning Server (APS) that provides various information for providing IPv6 service, and various setting values for providing IPv6 service. It may be configured to include an IPv6-only Auto Configuration Server (ACS) that provides IPv6-only Auto Configuration Server (ACS) and an IPv6-only Image Download Server (IDS) that provides IPv6-related firmware upgrade information.

The IPv4 service providing server may provide a specific service (or content) requested by a terminal through an IPv4 network.

The IPv6 service providing server may provide a specific service (or content) requested by a terminal through an IPv6 network.

Here, the service may include services such as a voice call, a video call, and a data call, but is not limited thereto.

A terminal according to an embodiment may be a low-end terminal that cannot simultaneously operate both IPv4 and IPv6 stacks in an IPv6/IPv4 dual network environment. Accordingly, the terminal may request IPv6 address allocation or IPv4 address allocation from the DHCP server. As an embodiment, the terminal may first request an IPv6 address from the DHCP server. This has the advantage of significantly reducing the probability of IP address allocation failure due to exhaustion of IPv4 addresses.

If the terminal fails to acquire the IPv6 address, it may request IPv4 address allocation from DHCP.

For example, the terminal may request IPv6 address allocation from the DHCP server upon initial opening or initialization. The terminal can access the IPv6 provisioning server using the IPv6 address allocated by the DHCP server and obtain various information for receiving the IPv6 service. Here, the information may include IP address information corresponding to the corresponding service providing server.

If the address system of the service providing server obtained from the IPv6 provisioning server is IPv6, the terminal can access the IPv6 service providing server using the information acquired from the IPv6 provisioning server and receive the corresponding service. However, when the address system of the service providing server acquired by the terminal from the IPv6 provisioning server is IPv4, the terminal may reboot and request IPv4 address allocation from the DHCP server.

The terminal obtains information by interworking with the IPv4 provisioning server using the IPv4 address allocated from the DHCP server, and accesses the IPv4 service providing server according to the obtained information to receive the corresponding service.

If the terminal fails to obtain an IPv6 address from the DHCP server upon initial opening or initialization, the terminal may request and obtain an IPv4 address allocation from the DHCP server. The terminal can obtain various types of information for receiving the IPv6 service by accessing the IPv4 provisioning server using the IPv4 address allocated by the DHCP server. Here, the information may include IP address information corresponding to the IPv4 service providing server. Thereafter, the terminal may access the IPv4 service providing server using the information acquired from the IPv4 provisioning server and receive the corresponding service.

The terminal may store IP address information corresponding to the last (or previous) accessed (or used) service providing server and/or information about the IP address system in an internal memory.

When the power is turned off during operation of the terminal and then turned on again, the terminal can determine which address system provisioning server to access based on the IP address information stored in the internal memory and/or the information on the IP address system. there is.

3 is a flowchart illustrating a method of selecting a service network of a terminal in an IPv4/IPv6 dual network upon initial opening or initialization of a terminal according to an embodiment.

Referring to FIG. 3 , the terminal may start a procedure for initial opening or a terminal initialization procedure (S301).

The terminal may acquire its own IP address from a dynamic host configuration protocol server (DHCP server) according to an initial opening procedure or a terminal initialization procedure. The terminal according to the embodiment may be implemented to attempt to acquire an IPv6 address by default when an initial opening procedure or a terminal initialization procedure is initiated.

The terminal may determine whether the IPv6 address allocation is successful (S302).

In step 302, if the IPv6 address allocation is successful, the terminal can interwork with the IPv6 provisioning server using the allocated IPv6 address (S303). The terminal may obtain a service server address by accessing the IPv6 provisioning server. Here, the service server address may include an address for an IPv6 service server. Of course, the service server address obtained by accessing the IPv6 provisioning server by the terminal may be an IPv4 address.

The terminal may determine whether the acquisition of the IPv6 service server address was successful (S304).

In step 305, if the acquisition of the IPv6 service server address is successful, the terminal can interwork with the IPv6 automatic configuration server and the IPv6 image download server (S305).

The terminal can automatically configure after obtaining various configuration information necessary for IPv6-based connection processing in conjunction with the IPv6 automatic configuration server. In addition, the terminal can automatically configure by downloading various firmware required for IPv6-based access processing in conjunction with the IPv6 image download server.

Thereafter, the terminal may receive the IPv6 service by interworking with the IPv6 service server (S306).

In step 302, if IPv6 address allocation fails, the terminal may attempt IPv4 address allocation from the dynamic host configuration protocol server (S307).

If the IPv4 address allocation is successful, the terminal can interwork with the IPv4 provisioning server using the allocated IPv4 address (S308). The terminal may acquire the IP address of the IPv4 service server by interworking with the IPv4 provisioning server. Here, the IPv4 provisioning server may include an IPv4 automatic configuration server and an IPv4 image download server.

The terminal can acquire and automatically set various configuration information required for IPv4-based access processing in conjunction with the IPv4 auto-configuration server. In addition, the terminal can automatically configure by downloading various firmware required for IPv4-based access processing in conjunction with the IPv4 image download server.

The terminal may receive the IPv4 service by interworking with the IPv4 service server (S309).

In step 304, if acquiring the IPv6 service server address fails, the terminal may automatically perform a booting operation (S310). For example, when the obtained service server address is not an IPv6 address or the obtained service server address is an IPv4 address, the terminal may determine that the acquisition of the IPv6 service address has failed.

The terminal may be assigned an IPv4 address from the dynamic host configuration protocol server (S311).

Thereafter, the terminal may interwork with the IPv4 provisioning server using the assigned IPv4 address (S312). The terminal may acquire the IP address of the IPv4 service server by interworking with the IPv4 provisioning server. Here, the IPv4 provisioning server may include an IPv4 automatic configuration server and an IPv4 image download server.

The terminal can acquire and automatically set various configuration information required for IPv4-based access processing in conjunction with the IPv4 auto-configuration server. In addition, the terminal can automatically configure by downloading various firmware required for IPv4-based access processing in conjunction with the IPv4 image download server.

The terminal may receive the IPv4 service by interworking with the IPv4 service server (S313).

In the embodiment of FIG. 3, the terminal internally transmits its own IP address information obtained from the dynamic host configuration protocol server and/or call server address information obtained by accessing the provisioning server - or information about the address system of the service server. can be stored in memory.

When the initial opening procedure and terminal initialization procedure of the terminal are completed and the power is turned off during normal operation and then turned on again, the terminal refers to the service server address information stored in the internal memory - or the information about the address system of the service server - and uses the previously used information. The address system of the service server can be identified. The terminal may receive a corresponding service by accessing a provisioning server corresponding to the identified service server address system.

4 is a flowchart illustrating a method of selecting a service network of a terminal in an IPv4/IPv6 dual network when the terminal is powered on or rebooted according to an embodiment.

Referring to FIG. 4 , the terminal may be powered off during operation and then turned on again or start a rebooting operation (S401).

The terminal may obtain a recently used service server address from an internal memory (S402).

The terminal may identify the address system based on the acquired service server address (S403).

The terminal may determine whether the identified address system is an IPv6 address system (S404).

As a result of the determination, in the case of the IPv6 address system, the terminal can interwork with the IPv6 provisioning server (S405).

The terminal may access the IPv6 provisioning server and obtain an address of a service server providing an IPv6-based service. Here, the IPv6 provisioning server is an IPv6 information providing server providing various information for providing IPv6-based services, an IPv6 automatic configuration server providing various setting values for providing IPv6-based services, and various firmware for providing IPv6-based services. May include an IPv6 image download server.

The terminal may receive the corresponding IPv6 service by interworking with the IPv6 service server corresponding to the obtained IP address of the IPv6 service server (S406).

As a result of the determination in step 404, if the identified address system is the IPv4 address system, the terminal can interwork with the IPv4 provisioning server (S407). The terminal may acquire the IP address of the IPv4 service server by interworking with the IPv4 provisioning server. Here, the IPv4 provisioning server is an IPv4 information providing server that provides various information for providing IPv4-based services, an IPv4 auto-configuration server that provides various setting values for providing IPv4-based services, and various firmware for providing IPv4-based services. An IPv4 image download server may be included.

The terminal may be provided with the IPv4 service by interworking with the IPv4 service server (S408).

In the above-described embodiments of FIGS. 3 and 4 , distinguishing between an operation of selecting a service upon initial opening or initialization of a terminal and an operation of selecting a service upon power off/on or rebooting during terminal operation may be to minimize booting time of the terminal. there is. That is, the IP address information of the service server obtained through the IP allocation procedure at the time of initial opening or initialization of the terminal - for example, information for identifying whether the service server is in the IPv6 system or the IPv4 system - can be stored in the internal memory of the terminal. there is. After that, the terminal can immediately identify the IP address system to be accessed by utilizing the IP address information of the service server stored in the internal memory, thereby minimizing the booting time of the terminal. However, in the case of a terminal where the service has not been opened, since the IP address of the previously used service server does not exist, the IP system of the service server to be accessed cannot be known. In addition, since all information stored in the internal memory of the terminal is deleted when the terminal is initialized, all IP address information of the previously used service server is also deleted.

Therefore, if the terminal is not opened or initialized for the first time, even if the power of the terminal is turned off / on or rebooted, the optimal service server access address system is based on the IP address information (or IP address system information) of the service server maintained in the internal memory. can be immediately identified, and through this, there is an advantage in that fast booting and fast call connection can be performed.
