Guide to Using the LTE Demonstration Services
1 Overview
The video-on-demand (VOD) service aims to play one or multiple high-definition videos using the mobile broadcast business platform (MBBSP). In the demonstration, you must check whether the video is smooth in the buffer time at the beginning and during the fourhour process of playing the video.
High-Definition Telepresence Telepresence Meeting
The high-definition telepresence meeting is a multi-party video conference conference realized by a telepresence system over the LTE network. As a new-generation high-definition video telepresence conferencee system, it features real-time panorama transmission and short delay. The conferenc telepresencee system has high requirements on the channel quality and the bit error rate (BER) telepresenc must be less than 2%. In the demonstration, you must check the consistency between video and voice, that is, the handover delay and handover bandwidth. Generally Generally,, a fixed-line UE needs no special optimization before accessing the LTE network. However, you need to check the handover parameters before a mobile UE connects to the network. This is because some on-site customers may participate in the conference during the demonstration. If the video is suspended or encounters mosaic effect, the customers will have bad impression on the LTE. In this sense, the high-definition telepresence meeting is of major importance among all the demonstration services.
High-Definition Mobile Editing Broadcast
The high-definition mobile editing broadcast is an evolution in social development mode brought by integration integration of the telecommunication telecommunication network and the radio, film and TV network after the LTE LTEtonetwork is developed. This service requires a high-definition video is delivered the eNodeB over an encoder containing a radio module. The camera. decoderThe on the peer end decodes decodes the video that is received received and broadcasts broadcasts it on the large-screen large-screen monitor. monitor. This service features high definition and flexible mobility but large delay (more than 2s) due to the processing of the the encoder and decoder decoder in the video transmission process. Therefore, you are are advised to place the camera out of vision of the monitor, protecting users from direct delay experience.
Multichannel Video Surveillance
In recent years, the video surveillance attracts more attentions. This service is specially designed to demonstrate that the LTE brings more flexible deployment schemes and more cost-effective cost-eff ective implementation.
Radio WIFI UE Demonstration
This service can be realized in a flexible method. At present, the customer premise equipment (CPE) is connected to a wireless router, which converts the LTE signals to WIFI signals. UEs such as the laptop, iPad, and mobile phone can access the Internet using WIFI. This service enables users to experience high-speed Internet surfing and FaceTime services.
Super-Speed Super-S peed On-line Game Playing
Currently,, there are a number of methods to demonstrate on-line game playing services. One Currently method is to connect two computers to the LTE network over separate LTE UEs to play interactive games together. together. Another method is to use the game UEs such PS3s to play interactive games over WIFI. Normally, the game services have low requirements on throughput but higher requirements on delay. Theref Therefore, ore, the demonstration process focuses on smoothness (delay) of the game.

4.1.6 LTE FAQs 1. Why is the throughput generally 1 Mbit/s and cannot reach the expected value during the uplink and downlink UDP packet transmission?
Answer: Check the following information elements contained in the S1AP-INITIALCONTEXT-SETUP-REQ message over the S1 interface to view the traffic transmission rate and QCI settings. 150 Mbit/s is recommended for both the uplink and downlink transmission rate.
The QCI ranges from 6 to 9. The value 5 is not recommended because 5 is used for IMS signaling.
If the settings of throughout and QCI are incorrect, contact the EPC engineers to modify the parameters. 2. Why does the throughput in UDP transmission reach the peak but the throughput in TCP transmission cannot?
Answer: Follow section 2.1" 2.1"UE Optimization" Optimization" to modify the parameters on both the server and the PC connected to the UE. For a multi-network-adapter system, ensure that parameters for each network adapter must be modified. For some systems, the MTU discovery switch needs to be configured. The following figure shows how to configure the MTU discovery.
3. Why cannot the terminal implement the dual streaming?
Answer: Check whether the MIMO mode is configured correctly correctly.. Run the following commands on the Web Web LMT according to the onsite situations (for example, the demonstration is performed indoors only.) to check the MIMO mode. Before running the command, back up default parameter settings so that you can resume the configurations after the demonstration.

Used to control the MIMO mode in single codeword or double codeword transmission. This parameter is valid when the ModeDivMuxSwitch is turned off.
FallBackAdaptiveSwitch
A switch that is used to enable the fallback from double codeword transmission to single codeword transmission.
4. Why does a Huawei UE in the FDD LTE have a throughput of around 25 Mbit/s only even if the signal is good?
Answer: Use the Probe to check whether the scheduling in the MCS is double codeword word.
That is, code0 and code1 must have corresponding scheduling. Alternatively Alternatively,, check the signaling trace over the UU interface to see whether the RRC_CONN_RECFG message contains the reconfiguration information about TM2 and TM3.
4.2 Cell-Peak-Throu Cell-Peak-Throughput ghput Demonstration 4.2.1 Overview The cell peak throughput demonstration mainly shows the total maximum data transmission rate of multiple UEs with optimum channels. Generally, a 20 MHz cell and one to two UEs are used in the cell peak throughput Generally, demonstration. One Huawei UE2.0 or two Commercial UEs are connected to the 20 MHz cell using optimum channels. Normally, Normally, the peak throughput in the 20 MHz cell is 150 Mbit/s in the downlink and 60 Mbit/s in the uplink.
4.2.2 Prerequisites 1. Check the prerequisites. See section 4.1.2"Prerequisites". Prerequisites". 2. Modify the number of PDCCH symbols to 1 by running the following commands:

4.2.5 Procedure Follow the single-UE commissioning method to have UE 1 access the network and reach the peak throughput, and and then have UE 2 access access the network network and reach the the peak throughput.
Test Procedure When a UE connects to the network, the Iperf tool on the PC connected to the UE acts as the client and the Iperf tool on the packet transmitting server acts as the server. Packets are transmitted from the server to the client by UDP/TCP. UDP/TCP. In the downlink peak throughput test, the number of PDCCH symbols must be modified from the default 3 to 1; otherwise, the downlink MCS cannot be set to 28. In this case, even if the value 28 is configured, a number of CRC errors occur and the throughput drops. Run the following MML command to modify the number of PDCCH symbols. MOD CELLPDCCHALGO: LocalCellId=0, InitPdcchSymNum=1, InitPdcchSymNum=1, PdcchSymNumSwitch=OFF;
Adjust the attenuator to have the UE position close to the center of the cell and set the downlink RSRP to a value ranging from –75 to –80 and average SINR to about 30 dB.
Observation Method Check the UE throughput at the application layer (the traffic volume of the network adapter on the PC) using the NetMeter software. NetMeter traffic traffic volume = Traffic Traffic volume at the application layer layer + Size of Ethernet Ethernet MAC overhead The throughput at the application layer on the PC can be observed by using the DU Meter or NetMeter.. The NetMeter is recommended. This is because the Netmeter calculates NetMeter calculates the traffic traffic volume of different network adapters and records the throughput in .txt format, facilitate report and analysis.
Traffic Volume of Single-UE Throughput For eRAN2.0, the throughput test is divided into UDP throughput test and TCP throughput test by service type. The test is performed by transmitting packets through the Iperf tool. However,, according to the experiences of other product lines and subscribers, data download However by TCP or FTP is recommended for for all the throughput tests in in eRAN2.1. Observe the test result of the cell peak throughput using the NetMeter NetMeter.. Ensure that the traffic volume is stable and investigate the cause in the case of sharp drop or fluctuation

Troubleshooting for TCP Peak Throughput TCP services include file upload or download by FTP in the DOS window, packet transmission by TCP using the Iperf in the DOS window, file upload or download using other FTP tools in the IE window, window, and email service. Common problems in TCP transmission include a throughput that is stable but rather lower than that of the UDP transmission, sharp throughput fluctuation, and interrupted data transmission. a.

Answer: This problem happens when the TCP window parameters fail to be modified. Check whether the parameters for peak throughput test are complete and the TCP window-related parameters are are configured correctly correctly.. b.
The traffic volume volume for uplink TCP transmission transmission fluctuates.
Answer: check whether the traffic volume for uplink UDP transmission is stable and successful; if not stable, adjust the quality of the uplink channel or SINR measurement mode. Then, check whether there is an uplink pre-scheduling function. If this function exists but is not enabled, enable this function. If the uplink pre-scheduling function does not exist, enable the fixed scheduling function. c.

Answer: IF the traffic volume for both uplink and downlink UDP transmission reaches the peak but the traffic traffic volume for uplink uplink TCP transmission is stable at about about 10 Mbit/s only, only, check whether the TCP window size among the TCPIP parameters in the registry on the PC connected to the UE is configured correctly. f.
The thr throug oughpu hputt is sta stable ble but the peak peak th throu roughp ghput ut is small. small.
Answer: This problem generally happens due to a small receiving window size, a small transmitting window size, or insufficient reverse traffic volume. To investigate the cause, perform the following following operations: 1. Check whether this is a TCP problem.
When a problem happens in TCP transmission, check the UDP transmission to check whether the same problem occurs. If the same problem occurs, check the UDP transmission to identify the cause and find a solution. Then, use the resolution to address the TCP problem. If the UDP transmission has no problem, go to step 2. 2. Check whether this is a TCP single-thread problem.
Check whether theisFTP serverorapplication is installed on the computer. If the FTP server application installed other similar applications aretransmitting installed, uninstall these applications, restart the computer, and then install the IIS application delivered with the system. After installation, installation, perform file download in one DOS window to see whether the problem still exists. If the problem remains or deteriorates, perform TCP tra transmission nsmission in two DOS windows to see whether the throughput is improved. If the throughput is improved, this is a TCP single-thread single-thread problem and you can can go to step 3. If the the throughput is not improved, this is a non-TCP singlethread problem and you can go to step 4. 3. Troubleshoot a TCP single-thread problem.
Use the following tool to modify the registry parameters on the laptop connected to the UE and the server. Then, start the computer.
TCP Parameter Modification Tool
If the problem remains after the computer is restarted, start the Ethereal or Wireshark Wireshark capture tool on both the transmitting and receiving sides, and then perform TCP single-thread transmission. Ensure that the link-establishing TCP packet can be traced. The tracing duration is about 10s. Compress and send the data that is traced to Huawei headquarters for analysis. 4. Troubleshoot a non-TCP single-thread problem.
Perform UDP transmission transmission in a reverse direction and check whether the throughput is normal. For example, if the downlink TCP transmission encounters a problem, perform uplink UDP transmission to check whether the uplink traffic volume is stable and has at least 40 bytes in MTU more than the downlink traffic volume. The default MTU is 1500 bytes. When the downlink traffic volume reaches reaches 50 Mbit/s, the uplink traffic volume is at least 1.33 Mbit/s. If the uplink traffic volume is unstable or insufficient, identify the uplink UDP problem and find a solution. Then, use the resolution to address the TCP problem. If the throughput in the UDP transmission along the reverse direction is normal, start the Ethereal or Wireshark Wireshark capture tool on both the transmitting and receiving sides, and then perform TCP TCP single-thread single-thread transmission. Ensure Ensure that the link-establishing link-establishing TCP packet can be traced. The tracing duration duration is about 10s. Compress and send the data that is traced to Huawei headquarterss for analysis. headquarter 5. The throughput fluctuates sharply.
Answer: This problem usually happens when the block b lock error ratio (BLER) over the air interface is high or changes sharply, the uplink dynamic scheduling is enabled during the downlink transmission, or the TCP layer encounters packet loss. To identify the problem, perform the following operations: 1. See steps 1 to 4 in problem 6. 6. Check whether packet loss occurs in the TCP transmission.
Enable the tracing function of the Ethereal on the transmitting or receiving side and then enter the tcp.analysis.duplicate_ack in the Filter box (no quotation mark is allowed). If the digit following the # under the TCP Dup ACK contained contained in the filter results, as shown in the following figure, or greater than 2, it indicates that some packets lost. the digit following theis#equal is 1, to there is no packet loss. The following figure showsget that theIfdigit following the # reaches 5, the packet loss occurs (the times of Dup ACK packet loss).
