Description
Technical Field
The invention relates to the field of communication, in particular to a method and a system for connecting a network by an Internet Protocol Version 4(IPv4, Internet Protocol Version 4)/Internet Protocol Version 6(IPv6, Internet Protocol Version 6) double-stack terminal.
Background
The internet, which is currently widely used worldwide, is based on the IPv4 protocol, and IP addresses are expressed in 32 bytes, theoretically about 40 hundred million, and practically only half of the addresses are available due to various limitations. In addition, in consideration of the fact that the demand for IP addresses will increase significantly in the coming years due to the development of 3G terminals, Internet Protocol (IP) phones, home networks, and the like, professional organizations predict that, in the first half of 2011, global IPv4 addresses will be allocated.
The Internet Engineering group (IESG, Internet Engineering SteeringGroup) 11/7 th 1994 is formally studied by using IPv6 as a standard. The IPv6 address adopts the 128-bit address length, and can provide addresses almost without limitation, and besides the defect of limited number of IPv4 addresses, the IPv6 protocol has the following advantages compared with the IPv4 protocol: the automatic equipment configuration capability provided by the IPv6 protocol can automatically identify new equipment of an access network and can carry out automatic configuration, which is very necessary for users with mobile and wireless access; many new security functions are supported in the IPv6 protocol family, such as: system-to-system authentication operations, encryption-based data transfer, and the like; the definition of the packet priority in the IPv6 protocol can better support real-time application programs; the multicast communication mechanism in the IPv6 protocol can provide a point-to-multipoint communication process under the premise of fully utilizing network resources.
As can be seen from the above trend, IPv6 is the developing direction of networks. In order to ensure that the terminal user can use the IPv4/IPv6 network simultaneously, the terminal needs to support the network which is connected and used with the IPv4 and the IPv6 at any time according to the needs of the user.
The 3GPP also finds this problem, and proposes a scheme in the version R8 in which an IPv4 address and an IPv6 address can be respectively obtained by activating a Packet Data Protocol (PDP) once. While the networks and terminals prior to the current version of R8 only support simultaneous connection to one network, namely: when the IPv4 network is connected, the IPv6 network cannot be connected unless the IPv4 network is disconnected first; and vice versa. Moreover, whether the IPv4 reset network is connected to the IPv6 or the IPv6 reset network is connected to the IPv4, the end user needs to manually perform corresponding connection operation, and for most of the ordinary mobile phone end users, the technical problem of IPv4/IPv6 network connection may not be known, so it is impractical to require the ordinary user to manually determine whether to establish IPv4/IPv6 connection and manually connect to the IPv4/IPv6 to be established. At present, no effective solution exists for the unrealistic problem of manual connection of IPv4/IPv 6.

Detailed Description
The basic idea of the invention is: setting a network priority connection strategy, and selecting a network with first priority connection according to the network priority connection strategy; the auto-reset network is connected to the IPv4/IPv6 network according to current network needs.
The following describes the embodiments in further detail with reference to the accompanying drawings.
As shown in fig. 1, a method for connecting a network by an IPv4/IPv6 dual-stack terminal includes the following steps:
Here, the network priority connection policy may be provided by the terminal. Further, the network priority connection policy provided on the terminal may provide the user to set the priority connection parameter. The preferred connection parameter is specifically included in the network preferred connection policy. Further, the network priority connection policy provided on the terminal may also determine to preferentially select the IP connection type according to the current access network type of the terminal. Here, it should be noted that: no matter what kind of network priority connection strategy is adopted, the terminal will be finally embodied as a priority connection parameter, and the terminal determines to be specifically connected to the IPv4/IPv6 network according to the value of the priority connection parameter.
And 102, selecting a network with initial preferential connection according to the network preferential connection strategy.
Here, the specific processing procedure of step 102 includes: when the value of the priority connection parameter is set to be 0, the terminal preferentially selects to connect the IPv4 network when connecting the network; alternatively, when the value of the priority connection parameter is set to 1, the terminal preferentially connects to the IPv6 network when connecting to the network.
And 103, automatically resetting the network to be connected to the IPv4/IPv6 network according to the current network requirement.
Here, in the above technical solution constituted by step 101 to step 102, after the setting of the priority connection parameter in step 101, the method further includes: and downloading and updating the set priority connection parameters through an air interface.
Wherein, the downloading and updating specifically comprises: when the downloaded priority connection parameter is the same as the value of the priority connection parameter set in the terminal, the currently set priority connection parameter is not updated; or, when the downloaded priority connection parameter is different from the value of the priority connection parameter set in the terminal, updating the currently set priority connection parameter, and assigning the value of the currently set priority connection parameter in the terminal to: a value of the downloaded priority connection parameter.
Since the initial network preference is different, the subsequent automatic network connection reset and service usage procedures are different, and therefore, they are described below.
In the first case: when the value of the priority connection parameter is set to 0, the case of connecting the IPv4 network is first selected with priority.
At this time, in step 102, automatically resetting the network connection according to the current network requirement specifically includes:
when the type of the opposite terminal address is an IPv6 network address, the service used by the terminal returns a message that the opposite terminal address is unreachable to the terminal; after receiving the message that the address of the opposite terminal is unreachable, the terminal automatically initiates an IPv4 connection PDP deactivation request; after the network successfully responds to the IPv4 connection PDP deactivation request and disconnects the IPv4 connection, the terminal automatically initiates an IPv6 connection PDP activation request and establishes an IPv6 connection.
Here, in a case that after the IPv4 and the IPv6 are respectively selected to be established in the first place and then, the terminal still receives a message that the peer address is not reachable, the method further includes: the terminal prompts the user that the service is unavailable, and simultaneously initiates an IPv6 connection PDP deactivation message to finish the flow of automatically resetting the network connection.
In the second case: when the value of the priority connection parameter is set to 1, the case of connecting the IPv6 network is first selected with priority.
At this time, in step 102, automatically resetting the network connection according to the current network requirement specifically includes:
when the type of the opposite terminal address is an IPv4 network address, the service used by the terminal returns a message that the opposite terminal address is unreachable to the terminal; after receiving the message that the address of the opposite terminal is unreachable, the terminal automatically initiates an IPv6 connection PDP deactivation request; after the network successfully responds to the IPv6 connection PDP deactivation request and disconnects the IPv6 connection, the terminal automatically initiates an IPv4 connection PDP activation request and establishes an IPv4 connection.
Here, in a case that after the IPv6 and the IPv4 are respectively selected to be established in the first place and then, the terminal still receives a message that the peer address is not reachable, the method further includes: the terminal prompts the user that the service is unavailable, and simultaneously initiates an IPv4 connection PDP deactivation message to finish the flow of automatically resetting the network connection.
In conclusion, the invention is a scheme that the terminal is intelligently connected to the IPv4/IPv6 network according to the requirement. The invention is different from the prior art that the terminal needs to be manually connected to the IPv4/IPv6 network, so that the same terminal supporting IPv4 and IPv6 can be intelligently and automatically connected to the IPv4/IPv6 network according to requirements. And, after connecting to the IPv4/IPv6 network, the same terminal supporting IPv4 and IPv6 can also use the IPv4/IPv6 network at the same time.
The invention mainly comprises the following contents:
a network priority connection strategy is preset on the terminal, the strategy specifically comprises a priority connection parameter, and when the value of the priority connection parameter is set to be 0, the terminal is connected with the IPv4 network preferentially when being connected with the network; when the value of the priority connection parameter is set to 1, the terminal will preferentially connect to the IPv6 network when connecting to the network. The priority connection parameter can be preset when leaving a factory according to the needs of an operator; but also can be downloaded through the air interface so as to update the corresponding priority connection parameter value.
When the IPv4 network is preferentially connected, namely: the value of the priority connection parameter is 0. The terminal initiates any PDP activation request for data connection, requests IPv4 network address from Gateway GPRS Support Node (GGSN), and establishes IPv4 network connection. When the service used by the terminal and the opposite terminal address type is the IPv4 network address, the terminal connection, namely the service use is the same as the current terminal processing; when the service used by the terminal and the opposite terminal address type is the IPv6 network address, the terminal will return the error that the opposite terminal address is not reachable, after receiving the return message, the terminal automatically initiates an IPv4 connection PDP deactivation request, after the network successfully responds to disconnect the IPv4 connection, automatically initiates an IPv6 connection PDP activation request, establishes an IPv6 data connection, and tries to use the current service again. If the opposite end address of the service can be reached, the service is normally used, if the opposite end address can still be returned to be unreachable, the user is prompted to have failed service access, and meanwhile, an IPv6 connection PDP deactivation message is initiated.
When the IPv6 network is preferentially connected, namely: the value of the priority connection parameter is 1. The terminal initiates any PDP activation request of data connection, requests IPv6 network address from GGSN, and establishes IPv6 network connection. When the service used by the terminal and the opposite terminal address type is the IPv6 network address, the terminal connection, namely the service use is the same as the current terminal processing; when the service used by the terminal and the opposite terminal address type is the IPv4 network address, the terminal will return the error that the opposite terminal address is not reachable, after receiving the return message, the terminal automatically initiates an IPv6 connection PDP deactivation request, after the network successfully responds to disconnect the IPv6 connection, automatically initiates an IPv4 connection PDP activation request, establishes an IPv4 data connection, and tries to use the current service again. If the opposite end address of the service can be reached, the service is normally used, if the opposite end address can still be returned to be unreachable, the user is prompted to have failed service access, and meanwhile, an IPv4 connection PDP deactivation message is initiated.
The priority connection parameter may be preset when the terminal leaves the factory, or downloaded through an air interface after each startup, and the terminal only retains the value of the priority connection parameter updated last time. An operator can set the value of the priority connection parameter to 0 if the overall IPv4 service is still in a majority position according to the current overall network condition, so that the terminal can be ensured to preferentially establish IPv4 connection to improve the connection efficiency; if the IPv6 service is in a majority position in the future, downloading and updating the priority connection parameter through the air interface, setting the value of the priority connection parameter to be 1, and ensuring that the terminal can preferentially establish the IPv6 connection so as to improve the connection efficiency.
The terminal provided by the invention can intelligently and automatically connect to the IPv4/IPv6 network according to the requirement, so that the terminal can automatically try another network connection without manual operation of the terminal user under the condition that the opposite-end network address is unreachable. And the connection efficiency is improved through the priority connection parameter in the network priority connection strategy, most meaningless PDP activation requests are reduced, and meanwhile, the value of the priority connection parameter can be updated at any time through downloading of an empty port, so that the terminal can be ensured to adapt to the current network requirement at any time.
The invention is illustrated below.
Table 1 below is a definition table of the priority connection parameters, and table 1 includes definitions of the priority connection parameters, parameter values, and corresponding parameter descriptions. Here, PDP _ ACT _ priority is defined as a priority connection parameter, and may be assigned a value of 0 or 1. Correspondingly, when the priority connection parameter is assigned to be 0, the terminal preferentially initiates a network connection request of the IPv4 when needing to access the network; when the priority connection parameter is assigned to be 1, the terminal will preferentially initiate a network connection request of the IPv6 when needing to access the network. The priority connection parameter list is stored in the terminal, and corresponding assignment can be carried out through preset or air interface downloading and updating.

| PDP_ACT_priority | 0/1 | Priority IPv4 connection/priority IPv6 connection |

And step 205, ending the OTA downloading process.

And step 304, after the terminal is successfully registered in the IPv4 network, the terminal normally uses the current service if the service used by the current terminal and the opposite terminal address can be reached, and the process is ended. If the opposite terminal address is not reachable, step 305 is skipped.
And 305, if the service opposite terminal address used by the current terminal is not reachable, the terminal initiates an IPv4 network connection PDP deactivation request, and after a network successful response is obtained, the terminal deactivates in an IPv4 network and disconnects the IPv4 connection.
And step 310, after the terminal is successfully registered in the IPv6 network, the terminal normally uses the current service if the service used by the current terminal and the address of the opposite terminal are reachable, and the process is ended. If the opposite terminal address is not reachable, step 311 is skipped.
And 311, if the service opposite terminal address used by the current terminal is not reachable, the terminal initiates an IPv6 network connection PDP deactivation request, and after a network success response is obtained, the terminal deactivates in the IPv6 network and disconnects the IPv6 connection.
