Application processing chip, smartphone system and network access method

Abstract

The invention relates to an application processing chip, a smartphone system and a network access method. The application processing chip comprises an IPv6 single-stack application program, a socket application program interface used for carrying out TCP / UDP protocol encapsulation on a data package of the IPv6 single-stack application program, and a universal serial bus driver used for carrying out data communication with a baseband processing chip. The application processing chip is characterized in that the application processing chip further comprises an IPv6 protocol stack module used for carrying out IPv6 protocol encapsulation on an IPv6 data package, an IPv6 address configuration and management module used for application of IPv6 addresses, configuration of IPv6 addresses assigned by a network side and IPv6 session management, and a PPPv6 encapsulation module used for carrying out PPP protocol encapsulation on the data package treated with IPv6 protocol encapsulation. According to the application processing chip, the smartphone system and the network access method, the IPv6 function is achieved by means of software upgrading of an AP chip in the smartphone system and modification of the mode of a BP chip in the smartphone system, and then the smartphone system does not rely on the BP chip with IPv6 processing capacity any more.

Description

technical field [0001] The invention relates to mobile terminal technology, in particular to an application processing chip, a smart phone system and a network access method. Background technique [0002] With the development of mobile terminal technology, smart phones have been widely accepted and used by people. Smartphone systems all have Application Processor (AP) chips and Baseband Processor (BP) chips. For the traditional system architecture of smart phones with IPv6 functions, see figure 1 . For the traditional system architecture of smartphones, if you want to implement IPv6 functions, you need to implement IPv6 modules and interfaces in both the AP chip and the BP chip, and set the IP Routing / Bridging (IP Routing / Bridging) module in the BP chip and include There are PPPv6 (PPP for IPv6) modules of the IPv6 Control Protocol (IPv6 Control Protocol, IPv6CP for short), and modules and interfaces such as IPv6 address configuration and management. [0003] When a smart...

Problems solved by technology

[0004] At present, some smart phones on the market do not have BP chips that can support IPv6 processing capabilities. If these smart phones do not undergo a large-scale hardware transformation, including replacing BP chips, they will not be able to implement IPv6 functions. It is very limited, and the cost of hardware modification and software upgrade after recycling is high, the workload is huge, and it also causes great inconvenience to users.
