Embodiment Construction

[0029] According to the technical solution disclosed by the present invention, in a heterogeneous network, a user terminal (which can be a personal desktop computer, a laptop computer, a tablet computer, a smart phone or other Internet access devices) uses multiple wireless network cards, and the service bandwidth of these network cards is superimposed on the Together. The hardware includes: using multiple wireless network cards, the quality of the wireless network card itself should be quite stable, and the compatibility between the wireless network cards should be good, and it should have good reliability, availability and load balancing, such as: 3G WCDMA network card and GSM network card . The software modules include: a search configuration module, a data transmission task allocation module, a transmission module, and a data merging module. An example is given below, assuming that the transmission module includes three wireless network cards: wireless network card A, wir...

Abstract

A bandwidth-superposed wireless internet access system and a bandwidth-superposed wireless internet access method are used for a user terminal in a heterogeneous network. The user terminal is used for network data parallel transmission through a plurality of wireless network cards. The communication process includes: initiating network search by the user terminal through the configured wireless network cards so that the wireless network cards obtain respective IP (internal protocol) addresses in the heterogeneous network; allocating communication request data packets to the obtained IP addresses and sending out the communication request data packets by the corresponding wireless network cards, so that a plurality of parallel data transmission channels are established; performing data transmission through different wireless network cards; and processing and combining data received by the channels so that one or more services are completed by means of restoration. By the aid of the technical scheme, the request data packets of one or more services are allocated to the wireless network cards with different IP addresses and sent out by the corresponding wireless network cards, so that the parallel data transmission channels are established, transmission speed is increased, and further, internet access speed is increased.

Description

technical field [0001] The invention relates to a service bandwidth superposition method, in particular to a system and method for multi-network card service bandwidth superposition in a heterogeneous network. Background technique [0002] The existing service bandwidth overlay solutions mainly include the following types: [0003] Solution 1: The way of batch processing commands. The method includes the following steps: using a computer program to modify the number of the built-in network card of the computer to realize the modification of the routing table. If the two networks are respectively connected to different ISPs (Internet Service Providers), using the batch processing command above, different network cards can be bound to different ISPs, and different network card links can be automatically invoked when accessing different ISPs to achieve the effect of bandwidth superposition. [0004] Option 2: hard routing. The method includes the following steps: by adding a...
