Problems solved by technology

[0005] Currently, in the UMTS system, the RNC and the NodeB, as two parties in the PPP protocol, are in an equal position during the process of PPP link negotiation. IP address, so that the RNC and NodeB cannot establish a transmission channel, and the terminal cannot call in

Embodiment Construction

[0039] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific examples, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention .

[0040] According to an embodiment of the present invention, the method for guaranteeing a transport layer link based on the PPP protocol includes the following steps:

[0041] (1) Establish a physical connection between the base station NodeB and the radio network controller RNC;

[0042] (2) The base station NodeB and the radio network controller RNC obtain the role identifiers used to represent their roles respectively based on the point-to-point protocol PPP negotiation, wherein the base station NodeB obtains the client role identifiers, and the radio network controller RNC obtains the server role identifiers. role identification;

[0043] (3) ...

Abstract

The invention relates to a method and a system based PPP (Point to Point Protocol) for protecting a transfer layer link. The method comprises the following steps: after a physical connection between a base station Node B and a radio network controller (RNC) is established, the base station Node B and the RNC negotiate and then respectively obtain role identifications for characterizing roles of the Node B and the RNC according to PPP; the base station Node B obtains the client role identification and the RNC obtains server role identification; and the base station Node B and RNC interacts according to the respective role identifications. According to the invention, the RNC and the base station Node B are assigned with roles to obtain the base station Node B of the client role identification to obtain a valid IP (Internet Protocol); an operation and maintenance channel is established by the IP and the RNC which obtains the server role identification; and the docking complexity of the RNC and the base station Node B is reduced by directly assigning other parameters from the RNC.

Description

technical field [0001] The present invention relates to the field of 3G UMTS (Universal Mobile Telecommunications System, universal mobile communication system) wireless communication, specifically, provides a kind of method and system based on PPP agreement guarantee transmission layer link, through PPP point to point protocol (Point to In the Point Protocol (referred to as PPP protocol), RNC (Radio Network Controller, wireless network controller) and NodeB (base station) at both ends of the link perform role configuration, and improve PPP negotiation to allocate and manage the IP address of the wide area network for the network transport layer application. Background technique [0002] The PPP protocol is a link layer protocol that carries network layer data packets on point-to-point links. Its advantages are simplicity, user authentication capabilities, and IP allocation. It is currently one of the most widely used protocols on the WAN. One, it is also a protocol widely ...
