Embodiment Construction

[0042] The inventor noticed during the invention that:

[0043] LTE (Long Term Evolution, long-term evolution) technology has broad development prospects as the mainstream technology of post-3G mobile communication, and EPC equipment is an important part of LTE network, its stability and reliability are very important. In order to ensure the high reliability and high stability of EPC equipment, it is inevitable to carry out a lot of testing work in the development and maintenance of equipment, among which the data transmission function test of S1-U interface is one of the key points of EPC equipment testing. However, due to the complexity of the S1-U interface protocol stack of EPC (such as figure 1 ), which contains the protocol stack for EPC and eNodeB communication (L1 / L2 / IP / UDP / GTP-U), while the upper layer payload is the protocol stack for communication between UE and PDN (IP / TCP or UDP / FTP orHTTP. ..), so it is difficult to directly develop the protocol stack of this in...

Abstract

The invention discloses equipment and a method for testing evolved packet core network equipment. The method comprises the following steps that: a first computer starts software which executes an upper-layer protocol of a protocol stack of an S1-U interface, generates data and then sends the generated data to a second computer; after receiving the data which is sent by the first computer, the second computer extracts an upper-layer protocol head of the protocol stack of the S1-U interface of the data and a data payload, packages the upper-layer protocol head and the data payload on a general packet radio service (GPRS) tunneling protocol for user plane (GRP-U) protocol head, and calls the protocol stack of an operating system to send the data to the evolved packet core network equipment through the S1-U interface; and after receiving the data which is sent by the evolved packet core network equipment through the S1-U interface, the second computer calls the operating system to peel off an internet protocol (IP) layer and the protocol head of a user datagram protocol (UDP) to obtain the data payload, removes the GRP-U protocol head of the data payload and then sends to the first computer through a data link layer. The invention is low in implementation cost, simple and easy in construction process, and easy in maintenance.

Description

technical field [0001] The invention relates to communication test technology, in particular to a test device and method for an evolved packet core network device. Background technique [0002] figure 1 It is a schematic diagram of EPC (Evolved Packet Core, evolved packet core network) system connection, figure 2 It is a schematic diagram of the S1-U interface protocol stack. According to the description of the 3GPP TS 23.401 protocol, the connection architecture between the EPC system and the eNodeB / UE (evolved base station / user equipment) and PDN (Packet Data Network, packet data network) can be simply configured by figure 1 indicated by figure 1 It can be known that the EPC is connected to the eNodeB through the S1 interface, and the S1-U interface is the user plane of the S1 interface. According to the 3GPP TS 23.401 protocol, the S1-U interface protocol stack is as follows figure 2 As shown, when the UE (User Equipment, user equipment) sends uplink service data, t...
