Problems solved by technology

[0004]However, there is usually only one PDP channel in the current data card, and only one PDP connection can be established at any time, so when initiating the second service, only the first Interrupt the PDP connection corresponding to the first service and give up the PDP channel to establish the PDP connection corresponding to the second service
The above-mentioned mode of setting up a PDP connection will inevitably bring the following disadvantages: 1. When carrying out the second service, the first service needs to be interrupted earlier, thereby causing the interruption of the first service; When the PDP connection of the service is connected, the PDP connection of the first service needs to be disconnected first, which will take a certain amount of time. If the user needs to frequently perform operations on multiple services, it will waste a lot of time for the user; When accessing the mailbox or conducting some e-commerce business, due to the arrival of the next business, when the current connection needs to be interrupted, then when the next business is completed, when the user wants to continue to access the mailbox or continue the e-commerce business, he may need to log in to the mailbox or 4. In the current TD-SCDMA / HSDPA network environment, when performing the second service, the first service needs to be interrupted first. This serial The PDP connection mode makes the utilization rate of the network not high
[0006] To sum up, there is no solution for simultaneously establishing multiple PDP connections in the prior art

Embodiment 1

[0042] Take the establishment of a PDP connection for the first time and the initiation of an Internet (Internet) service as an example for illustration.

[0043] (1) when initiating Internet business, select unit 21 to adopt the mode of next channel priority to carry out channel selection, because do not have any PDP business before, so select PDP channel 1; PDP context setting unit issues order AT+CGDCONT=1, "IP", "CMNET" are given to the data card, wherein, 1 refers to the numbering of the selected PDP channel; "IP" indicates that the packet switching protocol adopts the IP protocol; "CMNET" indicates the required APN to connect to the Internet;

[0044] (2) The determination unit 22 determines that the rate requested by the Internet service is 128 based on the preset strategy, and the data card can know the rate requested by the Internet service determined by the determination unit 22 by receiving the command AT+CGEQREQ=1, 2, 128, 128 rate. Among them, 1 still represents ...

Embodiment 2

[0048] Take continuing to initiate the MMS service as an example for illustration.

[0049] (1) When continuing to initiate the MMS service, the selection unit 21 adopts the next channel priority mode to carry out channel selection according to the information recorded in the recording unit 24, and the PDP channel 2 will be selected and assigned to the MMS service; Send instructions AT+CGDCONT=2, "IP", "CMWAP" to the data card, wherein, 2 refers to the number of the selected PDP channel; "IP" indicates that the packet switching protocol adopts the IP protocol; "CMWAP" indicates the connection the APN;

[0050] (2) The determination unit 22 determines that the rate requested by the MMS service is 128 based on a preset strategy, and the data card can know the requested rate of the MMS service determined by the determination unit 22 by receiving the command AT+CGEQREQ=2, 2, 128, 128 rate. Wherein, according to the order of the numbers on the right side of the equal sign: 2 stil...

Abstract

The invention discloses a method for establishing connection of grouped data protocol. The method comprises the following steps: selecting an unoccupied grouped data protocol channel from a data card having at least two grouped data protocol channels during initiating a current service; determining a rate required by the service on the basis of a preset strategy; applying to an access network of the service for the required rate through the selected grouped data protocol channel; allocating a rate for the service by the access network on the basis of the required rate; and establishing grouped data protocol connection corresponding to the service through the selected grouped data protocol channel. Accordingly, the invention also discloses a grouped data protocol connection device. The scheme of the invention can establish a plurality of grouped data protocol PDP connections at the same time, thereby realizing parallel development of multiple services, increasing efficiency and networkutilization rate and upgrading user experience.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for establishing a packet data protocol connection. Background technique [0002] In the era of Global System for Mobile Communication (GSM, Global System for Mobile Communication) / General Packet Radio Service (GPRS, General Packet Radio Service) / Enhanced Data Rates for GSM (EDGE, Enhanced Data rates for GSM Evolution) era, the downlink of the network The rate is theoretically between 8Kbps and 100Kbps, but the actual network downlink rate is also restricted by various environments and conditions, and it is difficult to reach the theoretical value. At such a low network rate, it is still difficult to access the network. Therefore, in the GSM / GPRS / EDGE era, there is no need to establish multiple packet data protocol (PDP, Packet Data Protocol) connections at the same time. The data card of the PDP channel establishes a PDP connection for a service...
