Abstract

PURPOSE: A method for embodying the functions of S02 and S04(Service Specifications 02 and 04) in a channel card is provided to minimize waste of codes and achieve a reliable channel card performance test by embodying S02 and S04 functions directly in a channel. CONSTITUTION: An S02/S09 initializing unit initializes S02 or S09 service. A mobile terminal loop back call setup unit sets up a loop back call with a mobile terminal in response to the initialization. A packet generation unit generates the first traffic packet for the mobile terminal. An MSU(Multiplex Service Unit) makes the traffic packet into a traffic frame, and transmits it to the terminal. A received traffic frame processing unit receives the traffic frame looped back from the terminal, extracts packet information from the traffic frame to determine a packet type, and transmits it to a received packet processing unit. The received packet processing unit processes the received packet and generates statistics data. The received packet processing unit calls the packet generation unit and makes a reference packet. A statistics data reporting unit makes collected S02 or S09 statistics data into a format to send them to a display block, and transmits them to the display block periodically according to a fixed IPC format.

Description

How to Implement Service Specification 2 and 9 Function in Channel Card

The present invention relates to the implementation of the function of the PCS / DCS of the CDMA system in the form of a mixture of the mobile station loopback service specification standard specified in TIA / EIA / IS-126-A.

In the related art, the base station controller (BSC) implements the loop back service specification standard specified in TIA / EIA / IS-126-A. In other words, TSB of base station BSC generates packet of service 02 and service 09 and sends it to channel card of BTS, and receives the loopback packet from terminal from channel card and compares with standard packet to calculate statistics on forward and reverse links. Follow. Therefore, in order to use the functions of service specifications 2 and 9 (S02 and S09), the BSC, BSM, and BTS must be linked and operate normally. Therefore, when installing BTS for the first time in a system manufacturing plant or cell site, BSC and BSM are required when testing BTS using S02 and S09, which caused much inconvenience in the test. In addition, the software units for S02 and S09 in the TSB of BSC are also implemented separately, which leads to a lot of code waste, and even when S02 and S09 are used for the performance test of the channel card, it is wrong in some places when unexpected results are obtained. It was a difficult problem to figure out.

In order to solve this problem, the present inventors solved the above-mentioned problems by implementing the functions of S02 and S09 directly on the channel card, considering that the above-mentioned problems can be solved if the S02 and S09 functions are possible in the channel card in the BTS. For the purpose.

The present invention for achieving the above object, the step of initializing the S02 or S09 service, the step of setting up the loopback CALL with the mobile station in response to the initialization, the first according to the predetermined service level for the mobile station in accordance with the setup; Generating a packet and regenerating the packet as a traffic packet according to a predetermined class of each service and transmitting the packet to a terminal through a communication unit of the channel card. Receiving a loopback frame from the terminal, extracting packet information from the received frame, determining a packet type, and transmitting the packet type to a receiving packet processor; processing the receiving packet to generate statistical data and calling the packet generating unit; And a step of making a reference packet and sending the collected S02 or S09 statistical data to a display block and periodically sending the collected S02 or S09 statistical data to the display block according to a predetermined IPC format.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The above-mentioned problems and objects and configurations of the present invention will be described in detail with reference to the accompanying drawings.

First, the detailed configuration of the channel card of the present invention will be described in detail, and the configuration can be summarized in the following seven units.

(1) S02, S09 initialization unit

This unit initializes the relevant parameters and prepares for the mobile station loopback CALL setup with the terminal when the channel card is instructed by the BTS control processor to operate in S02 or S09 mode.

(2) Mobile station loopback CALL setup unit

It is a unit that operates the terminal, service environment setup and service procedures for mobile station loopback CALL setup. The unit determines the service type, packet type, etc. of the channel card and the terminal, and when this process is completed, the channel card and the terminal start operation in the determined service mode.

(3) packet generation unit

The unit creates the first traffic packet to be sent to the terminal, in the case of S02 with 171, 80, 40, 16 or 0 depending on the class specified, and in the case of S09 with 266, 124, 54, 20 or 0 bits. Generate. The generated traffic packet is sent to the terminal through the multiplex service unit (MSU). This unit is also used to generate a reference packet to compare packets that have been looped back from the terminal.

(4) Multiple Sublayer Units (MSUs)

This unit generates traffic frames of the packet generation unit in the form of multiplex specification 1 in case of S02 and multiplex specification 2 in case of S09. This channel is then sent to the terminal via the transmission unit of the channel card.

(5) received traffic frame processing unit

This unit receives the traffic frames looped back from the terminal and determines the packet type (class 1, 1/2, .1 / 4, 1/8, blank) according to the multiple sublayers (MSU). Then, the bits according to the packet type are extracted from the received frame and sent to the receiving packet processing unit together with the packet type information. The unit also processes control signal messages received from the terminal.

(6) Receive Packet Processing Unit

This unit processes the packets received from the received traffic frame processing unit to generate statistical data. This unit makes a reference packet from the packet generation unit and compares it with the packet received from the terminal and stores statistical data about it. In addition, the information necessary to generate the reference packet is stored in a buffer for the transmission packet in advance.

(7) statistical data reporting unit

This unit formats the collected S02 or S09 statistical data to the display block and periodically sends it to the display block according to the specified IPC format.

The software for controlling the communication of messages to the components implemented on the channel card in the above BTS will be described with reference to FIG. When the S02 or S09 service is initialized under the control of the base station BTS controller, the process proceeds to a loopback CALL setup procedure for the mobile station to initiate transmission and reception packet processing. Accordingly, the channel card manages transmission by generating transmission / reception packet, multiplexing control, and traffic frame according to a predetermined service standard.

It is worth noting that a feature of the present invention is that the software for integrating and managing the control flow of services 2 and 9 is built into the BTS and the control is operated as an independent process by the BTS itself.

As described above, the service specifications 2 and 9 implemented on the channel card of the present invention are performed in the BTS without the need for interworking between the BSC and the BSM. There is an advantage to this.
