Embodiment Construction

[0037] Existing channel detection methods cannot detect channels in a hybrid network. In addition, whether it is ATM's OAM or IP's ICMP, it can only detect the underlying transmission in the interface protocol stack, and cannot detect the relevant information of the upper-layer user instance, so it is impossible to achieve no traffic through calls and repeated deletion of public channels. Diagnosis of user instance problems.

[0038] In order to solve the above problems, an embodiment of the present invention provides a channel detection method based on a user plane. In the embodiment of the present invention, the intermediate network node forwards the upper-layer protocol detection message between the first transmission network and the second transmission network, so as to complete the channel detection in the hybrid networking. The first transmission network and the second transmission network may be ATM transmission network or IP transmission network. Using the channel de...

Abstract

The invention provides a channel detection method, a device and a system thereof, relates to the data transmission field, and solves the problem that mixed networking can not be detected in the existing channel detection method. The channel detection method comprises the following steps: receiving an upper layer protocol detection message sent by a first transport network through a channel to be detected, and then packaging the upper layer protocol detection message in the package format of the first transport network; and analyzing and packaging the upper layer protocol detection message in the package format of a second transport network, and then sending the message to the second transport network through the channel to be detected. The technical proposal provided by the invention is applicable to a UMTS network.

Description

technical field [0001] The present invention relates to the field of data transmission, in particular to a channel detection method, device and system in a UMTS (Universal MobileTelecommunications System, universal mobile communication system) network. Background technique [0002] With the evolution of 3GPP, the transmission architecture of WCMDA and TDSCDMA is also gradually evolving to all-IP: IUB, IUR, IUCS, NB and other interface transmissions are no longer purely ATM / AAL2 or IP / UDP, and even an interface is made by ATM and IP mixed composition, for example, the following IP and ATM transmission mixed with each other networking: [0003] Networking 1: NODEB——ATM——relay node 1——IP——relay node 2——ATM——RNC; [0004] Networking 2: NODEB——ATM——RNC——IP——RNC——ATM——MGW. [0005] In the case of mixed networking, neither F4 / F5OAM of traditional ATM nor ICMP of IP can detect end-to-end (for example, RNC to NODEB in networking 1) user transmission channel failure. (User transmis...
