Problems solved by technology

[0005] Since the protocol stacks of the AGPS SUPL application and other PS services run on different processors, it is impossible to use the same APN to establish different data links; in addition, the Modem processor must have a SUPL protocol stack for The analysis and encapsulation of the AGPS SUPL statement, and needs to have its own TCP / IP protocol stack for TCP / IP analysis and encapsulation, which makes the structure of the Modem processor more complicated

Embodiment Construction

[0020] The embodiment of the present invention provides a method and device for sharing data links of multiple packet data services, specifically, the protocol stack of SUPL is set on the application processor, and the TCP / IP protocol stack originally located in the Modem processor does not need After re-establishment, it is enough to directly use the existing TCP / IP protocol stack of the application processor, and handle AGPS SUPL as a PS service of the application processor, so that the AGPS SUPL can use the data link established on the application processor To transmit data, AGPS SUPL and PS services using the same access point name APN information can share the same data link to achieve concurrency. The implementation of the above-mentioned technical solution can realize that the AGPS SUPL application and other PS services use the same APN information and realize concurrency on the same data link; at the same time, the design structure of the Modem processor can be simplifi...

Abstract

The embodiment of the invention provides a method and a device for sharing a data link by a plurality of grouped data services. The method comprises the following steps of: firstly, setting a protocol stack on an application processor, wherein an AGPS (Assisted Global Positioning System) accords with an SUPL(Secure User Plane Location) interface; then, processing AGPS SUPI as a data classification, i.e. a PS (Process Subscriber) service of the application processor by using a TCP / IP protocol stack existing in the application processor; and sharing the same data link by the AGPS SUPI and the PS service using the same APN (Access Point Name) information. By the technical scheme, the invention can share the same APN information by the AGPS SUPI application and other PS services and realizes concurrency on the same data link. Meanwhile, the invention can simplify the design structure of a Modem processor.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and a device for sharing a data link by multiple packet data services. Background technique [0002] Currently, when a terminal accesses the Internet in a wireless manner, it is first necessary to set an access point name (APN, Access Point Name), and then initiate a process of activating a packet data protocol (PDP, Packet Data Protocol). The difference of APN determines the difference of the packet network to be accessed. Generally, operators will use different APNs to distinguish different data classification (PS, Packet Switch) applications, but if operators are unwilling to deploy more APNs to distinguish different For PS services, two PS services or multiple PS services need to use the same APN information, but generally if the protocol stacks supporting PS services run on different processors, such as application processors and Modem processors, then they shar...
