Embodiment Construction

[0043] The protocol emulator and its test processing method of the present invention, according to the flow specified in the RLC protocol in 3GPP, completes the channel reconfiguration through a simple way of triggering the flow, so that some functions that cannot be realized by the instrument can be realized without testing Humans additionally write complex link management code.

[0044] Before the present invention is described in detail, a scene of channel reconfiguration is firstly described.

[0045] When UE (User Equipment) switches cells, performs carrier frequency switching in the same cell, and switches between CELL_DCH (Cell Dedicated Channel State) and CELL_FACH (Cell Forward Access State), the physical resource mapped by the RLC resource used by the terminal Or if the transmission channel resource changes, channel reconfiguration needs to be performed.

[0046] In the specific embodiment of the present invention, the mobile communication terminal is switched from ...

Abstract

The invention provides a protocol simulator and a method for testing user equipment (UE) thereby. The method is used for UE test, and relates to a case of channel reallocation. The method comprises the following steps: a first transmission step in which the protocol simulator and the UE perform transmission of an acknowledgement mode data protocol data unit (AMD PDU) in a first channel; a second transmission step in which the protocol simulator and the UE perform the transmission of the AMD PDU in a second channel different from the first channel; a reset message sending step in which the protocol simulator sends a radio link control reset message to the UE; and a reallocation message sending step in which the protocol simulator sends a radio resource control reallocation message to the UE. The method avoids a flow error caused by an RLC error when performing a high-level protocol test on the UE, reduces the complexity of implementing a test flow by the stimulator, effectively reduces the test cost and improves the test accuracy.

Description

technical field [0001] The invention relates to a test of a mobile communication terminal, in particular to a protocol emulator and a method for testing user equipment. Background technique [0002] After the 3G terminal establishes the connection mode, for example, in CELL_DCH (dedicated channel state of the cell) and CELL_FACH (forward access state of the cell), it maintains the connection of the uplink and downlink signaling with the network through the logical channel at the same time, and in the RRC (radio resource control ) The most important information in the signaling connection is transmitted through a logical channel mapped in AM (acknowledgment) mode to ensure that important data can be correctly received by the receiving end. The above-mentioned mechanism complies with the provisions of the RLC (Radio Link Control) layer protocol in the 25.321 protocol of the 3GPP (3rd Generation Partnership Project). [0003] According to the RLC protocol, the sender sends an ...
