Mobile terminal multi-APN network channel concurrent network system and creation method thereof

Abstract

Provided are a mobile terminal multi-APN network channel concurrent network system and method for creating same, aiming at providing a method for establishing a multi-APN networking channel in the operating system of a mobile terminal and supporting the operating system of the mobile terminal, and application software to realize multi-APN concurrent networking. The present invention is implemented via the following technical solution: a multi-APN networking channel module is disposed between an application layer containing the operating system of the mobile terminal and the application software and the drive module of a bottom layer; the application layer sequentially issues at least two APN networking instructions to the multi-APN networking channel module, and the multi-APN networking channel module sequentially creates or allocates at least one path of a virtual network unit according to the networking instructions, and the drive module parses each APN parameter from the received networking request, initiates a network connection according to each APN parameter, and transmits to a mobile base station the networking request; and the multi-APN networking channel module sets for the created or allocated virtual network unit the parameters in each networking success message returned by the drive module.

Description

Technical field: [0001] The invention relates to a mobile terminal operating system and a system and a creation method for realizing sequential activation of multiple APN network channels and concurrent network connections in operating system application software. Background technique [0002] For ordinary users, APN (AccessPointName, Access Point Name) is just a group of parameters pre-configured or manually set on the mobile terminal for surfing the Internet. For the mobile network, the APN is an essential identification used to implement the routing of the user's Internet protocol IP message to the corresponding GPRS network router GGSN and the external network. Its role specifically includes: APN as a routing identification: GPRS service support node SGSN According to the APN, query the GGSN IP address corresponding to the APN from the DNS server of the specific domain name system to determine the GGSN that the user should access; Different service domains correspond to...

Problems solved by technology

First of all, the public shared work queue cannot provide more benefits, because if any of the work items is blocked, other work items will not be executed, so in actual use, users will create work queues by themselves, and This in turn leads to the following problems: MT's work queue causes the number of threads in the kernel to increase very quickly, which brings some problems: one is that it takes up the number of pids, which is not good news for the server, because the pid actually It is a global resource; and the competition of a large number of worker threads for resources also leads to invalid scheduling, which is actually unnecessary and puts pressure on the scheduler

The existing work queue mechanism has a tendency to cause deadlocks in some cases, especially when there are dependencies between two work items

If you've ever debugged this occasional deadlock, you know how frustrating it can be
