Description

  The present invention relates to a pseudo base station apparatus for testing a terminal under test such as a portable terminal, and more particularly, to a pseudo base station apparatus that simulates a device on a communication line side with respect to a terminal under test such as a base station or an opposite terminal. Is.

  Conventionally, as a pseudo base station apparatus for testing a terminal under test, for example, each communication information sequentially transmitted and received between a communication unit that transmits and receives various types of communication information with the terminal under test and the terminal under test The log information displayed in the display unit is detected when the log information is sequentially detected, the detected multiple log information is stored and retained as trace information, and the multiple log information constituting the stored trace information is displayed on the display unit. A filter marker is added to log information having specified information among a plurality of pieces of log information constituting information, so that specified log information can be easily identified among sequentially detected log information. (For example, refer to Patent Document 1).

  On the other hand, in mobile communication performed in accordance with the W-CDMA (Wideband Code Division Multiple Access) communication method, etc., HSDPA (High Speed Downlink Packet Access) defined in 3GPP (3rd Generation Partnership Project) standard TS25.308 ) And HSUPA (High Speed Uplink Packet Access) have come to be adopted, so that the amount of information transmitted and received by the pseudo base station apparatus to and from the terminal under test increases, and processing is performed per unit time. The amount of trace information that needs to be increased.

For this reason, in the pseudo base station apparatus, the capacity of a bus or buffer for internally transferring information (communication messages, data, etc.) and trace information related to communication may be insufficient. In order to prevent such a shortage of internal bus and buffer capacity, the conventional pseudo base station apparatus is less important than communication information when the internal bus and buffer capacity shortage occurs It was necessary to limit the transfer of trace information.
