Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Currently, in a satellite mobile communication system, a terminal tester is generally used to test the functional characteristics of a handheld terminal in an indoor environment, and when a packet domain service of the handheld terminal is tested by the terminal tester, different test scenarios are often required to be constructed according to different configuration parameters, such as different spot beam configuration parameters, different Radio Bearer (RB) resource air interface configuration parameters, and the like, to perform a test on the packet domain function. Therefore, in order to achieve the purpose of meeting the requirements of different scenes and different test parameters, different parameters and test cases are required to be constructed according to different scenes, and more repetitive work is needed, and the maintenance is not facilitated.
According to the requirement of satellite-to-satellite testing, the handheld terminal needs to support 9.6Kbit/S satellite-to-satellite data service. In order to achieve the test rate of the handheld terminal of 9.6Kbit/s, according to theoretical data, 3 frames of uplink transmission opportunities are needed in at least 6 frames of periods, so that the rate requirement of the terminal can be met. According to the current communication system, when testing the high-speed packet domain service, usually the gateway station will continuously send a plurality of downlink bursts, and then the terminal will continuously send a plurality of uplink bursts according to the uplink scheduling issued by the gateway station, instead of alternately sending and receiving. Meanwhile, due to the satellite communication packet service, according to the characteristics of transmission and reception, which are the characteristics of the multi-level and multi-level, when the terminal receives the uplink scheduling, it is necessary to transmit uplink data in the following consecutive N bursts. Therefore, the tester needs to schedule the uplink transmission opportunity of the terminal as sufficiently as possible at the time of receiving at the terminal, and does not transmit a new uplink schedule to the terminal when the terminal is in a transmission state, thereby ensuring that the rate meets the requirement.
In order to meet the maximum scheduling, that is, scheduling as many as possible when the terminal is in a receiving state, and not scheduling when the terminal is in a transmitting state, parameters such as an uplink initial transmission frame number, an uplink initial transmission time slot, an uplink burst duration number, an uplink duration frame number, an uplink end time slot and the like when the terminal receives the scheduled data each time need to be calculated on the tester side, and then the uplink transmission of the terminal is continuously scheduled after the terminal is switched to the receiving state under the condition that the radio frequency transceiving switching of the terminal is ensured to occupy 1 time slot. Based on this, according to the packet domain scheduling method and apparatus for the terminal tester provided by the embodiments of the present invention, the terminal tester receives the script parameters sent by the script, stores and uses the script parameters to configure the configurable test case, establishes the spot beam and sends the broadcast information to the terminal, and performs scheduling according to the configured configurable test case after receiving the packet domain service information sent by the terminal. Maintenance efficiency can be increased, and repetitive work can be reduced.
To facilitate understanding of the present embodiment, first, a packet domain scheduling method for a terminal tester disclosed in the present embodiment is described in detail.
Example 1
and step S102, receiving script parameters sent by the script.
And compiling the script through a Testing and Test Control Notation (TTCN), wherein the TTCN is a scripting language and is used for compiling script parameters, after the script parameters are compiled, the TTCN sends the compiled script parameters to a tester L1, and the tester L1 refers to a processing module of the terminal tester. After the TTCN is used for writing the script, each input parameter is set according to the configuration interface of the configurable test case, the configurable test case is executed, and the script sends the parameters to the tester L1.
The script parameters comprise spot beam public configuration parameters and air interface resource configuration public parameters; the spot beam common configuration parameters at least comprise an SB _ FRAME _ TS _ OFFSET parameter, an SB _ SYMBOL _ OFFSET parameter, a MAC _ RETURN _ TS _ OFFSET parameter, a MAC _ FORWARD _ TS _ OFFSET parameter and a USF _ DELAY parameter; the common parameters for the configuration of the air interface resources of the packet domain at least comprise a terminal uplink scheduling time slot parameter, a tester packet domain downlink sending time slot parameter, a terminal uplink sending initial time slot parameter, an uplink burst number parameter and a downlink burst number parameter. For the script parameter settings, the numeric references given in table 1 may be followed.
As can be seen from the content given in table 1, for the spot beam common configuration parameter, the value of SB _ FRAME _ TS _ OFFSET parameter is 32, the value of SB _ SYMBOL _ OFFSET parameter is 0, the value of MAC _ RETURN _ TS _ OFFSET parameter is 0, the value of MAC _ FORWARD _ TS _ OFFSET parameter is 0, and the value of G _ USF _ DELAY parameter is 3. The SB _ FRAME _ TS _ OFFSET parameter indicates a timing OFFSET between the nth FRAME time slot 0 of the forward link and the N +5 th FRAME time slot 0 of the reverse link at the beam center point for the MES (earth mobile station), which is a terminal for performing a test in general. The SB _ SYMBOL _ OFFSET parameter indicates the timing OFFSET of the beam center point for the MES. The MAC _ RETURN _ TS _ OFFSET parameter is the OFFSET of the upstream MAC (medium access control) slot relative to the absolute start of the frame. MAC _ FORWARD _ TS _ OFFSET is the OFFSET of the downstream MAC slot relative to the absolute start of the frame. And the USF _ DELAY is used for calculating the uplink transmission frame number corresponding to the allocated USF. The value of the G _ USF _ DELAY parameter in table 1 is 3, which is the USF _ DELAY value issued in the system message of the air interface, and the value added by 4 is the actual USF _ DELAY value used by the terminal, that is, the actual USF _ DELAY value used by the terminal is 3+4 — 7.
According to the content given in table 1, a common parameter is configured for the air interface resource of the packet domain, where a value of the terminal uplink scheduling time slot parameter is '11000000' B, a value of the tester packet domain downlink transmission time slot parameter is '11000000' B, a value of the terminal uplink transmission start time slot parameter is '11000000' B, a value of the uplink burst number parameter is 4, and a value of the downlink burst number parameter is 2. Where a frame has 40 slots, each bit position represents 5 slots. The leftmost 1bit represents 0-4 time slots, and the rightmost side is 35-39 time slots. Therefore, the '11000000' B represents the gap of 0 to 9.
As can be seen from the contents given in table 1, other script parameters, such as physical layer burst type, modulation and coding scheme, tester downlink transmission position, etc., can also be set. Wherein, the G _ BANDWIDTH parameter in table 1 is the physical layer burst type setting, the value of G _ BANDWIDTH is 1, which represents that the physical layer burst type selects PNB110, i.e. one burst occupies 10 time slots; the G _ PDCH _ MCS parameter in table 1 is the modulation and coding scheme, and if the G _ PDCH _ MCS parameter is 2, it means that the modulation and coding scheme is high speed, and if the G _ PDCH _ MCS parameter is 0, it means that the modulation and coding scheme is low speed; the G _ DL _ SND _ MACSLOT parameter in table 1 is the downlink transmission position of the tester, and the value of '11110000' B in table 1 means that the downlink transmission position of the tester is 0-39 time slots.
The parameters and values thereof shown in table 1 are scripted through TTCN, it should be noted that the value range is not necessarily the range shown in table 1, and corresponding modifications may be made, and the input parameters may also be increased or decreased.
And step S104, storing the script parameters and configuring the script parameters to the configurable test case.
After the terminal tester receives the script parameters sent by the TTCN, the terminal tester stores the script parameters, configures the script parameters to the configurable test cases stored in the terminal tester according to the content and the value of the script parameters, and completes the configuration work of the configurable test cases.
And step S106, establishing spot beams according to the configurable test cases, and sending broadcast information to the terminal.
The terminal tester establishes a spot beam by using the configured configurable test case, and then the terminal tester sends broadcast information to the terminal, wherein the terminal is generally an MES.
And step S108, receiving the packet domain service information sent by the terminal, and scheduling according to the configured configurable test case.
The terminal initiates the packet domain service after receiving the broadcast information, and simultaneously sends the packet domain service information to the terminal tester, and after the terminal tester receives the packet domain service information sent by the terminal, the terminal tester adopts the configured configurable test case for scheduling. Taking the parameters and values shown in table 1 as an example, the scheduling policy of the terminal tester adopts the manner shown in table 1, that is, the terminal schedules the uplink data in the time slots 0 to 9 of the N frame, the N +1 frame, and the N +2 frame, after receiving the scheduling, the terminal will continuously transmit 12 uplink bursts starting from 32 time slots of the N +2 frame, and the transmission continues until 31 time slots of the N +5 th frame end, and the terminal will switch to the receiving mode. And then, the terminal tester schedules the uplink data of the terminal in the 0-9 time slots of the (N + 6) th frame, the (N + 7) th frame and the (N + 8) th frame, the terminal continuously sends 12 uplink bursts from the 32 time slots of the (N + 8) th frame after receiving the scheduling, the sending lasts until the 31 time slots of the (N + 11) th frame are finished, and the terminal is switched to a receiving mode. And then, the terminal tester continuously schedules the terminal according to the rule.
Referring to fig. 2, a time slot schematic diagram of a scheduling method of a packet domain of a terminal tester is shown, where a light color part in fig. 2 is an uplink transmission time slot of a terminal, and a dark color part is a time slot that can be received by a downlink of the terminal. As shown in fig. 2, according to the configuration scenario of the satellite test, the physical layer burst type selects PNB110 (one burst occupies 10 slots), MCS is 2, SB _ FRAME _ TS _ OFFSET is 32, SB _ SYMBOL _ OFFSET is 0, MAC _ FORWARD _ TS _ OFFSET is 0, MAC _ RETURN _ TS _ OFFSET is 0, USF _ DELAY is 7, an air interface RB (radio bearer) establishes and configures an uplink initial transmission slot of the terminal to be 0 to 9, the uplink scheduling slot of the terminal on the tester side is configured to be 0 to 9, and 2-down-4 configurations are adopted, that is, the terminal needs to continuously transmit 4 uplink bursts when the transmission slot arrives after receiving one uplink scheduling.
For example, the terminal receives the uplink scheduling matched with the USF allocated to the terminal in the nth frame, and according to the calculation result of the parameters configured by the air interface, the terminal needs to start to continuously send 4 uplink bursts in 32 time slots of the (N + 2) th frame, and meanwhile, the terminal can continue to receive downlink in the whole frame of the (N + 1) th frame and the first 30 time slots of the (N + 2) th frame, and continuously send the uplink scheduling to the terminal in the downlink by adopting 0-9 time slots of the (N + 1) th frame and the (N + 2) th frame. Since the terminal receives uplink scheduling in the nth frame, the N +1 frame, and the N +2 frame, according to the USF _ DELAY and the number of air interface long DELAY frames, the terminal will continuously send 12 uplink bursts from 32 timeslots of the N +2 frame, and send the first 31 timeslots that will cover 8 timeslots, the N +3 frame, the N +4 frame, and the N +5 frame after the N +2 frame. In this configuration, the theoretical rate is (296 × 12)/(6 × 0.06) ═ 9.867kbit/s, where 296 is the length of one burst, 12 total number of upstream bursts, 6 is the total number of frames for one cycle duration, and the time of one frame is 0.06 seconds.
Referring to fig. 3, a schematic time slot diagram of another scheduling method for a packet domain of a terminal tester is shown, in fig. 3, a light color part is an uplink transmission time slot of a terminal, and a dark color part is a time slot that can be received by a downlink of the terminal. As shown in fig. 3, according to the configuration scenario of the satellite test, the physical layer burst type selects the PNB110 (one burst occupies 10 slots), MCS is 2, SB _ FRAME _ TS _ OFFSET is 32, SB _ SYMBOL _ OFFSET is 0, MAC _ FORWARD _ TS _ OFFSET is 0, MAC _ RETURN _ TS _ OFFSET is 0, USF _ DELAY is 7, and USF _ DELAY is a system message parameter, and when 7, it represents that the terminal needs to receive the uplink data sent by the terminal at the N +7 th FRAME after receiving the schedule at the nth FRAME. Due to the delay of the satellite link, when the delay is set to 5 frames by simulation, the terminal needs to transmit data in the N +2 th frame, so that the data transmitted by the terminal arrives at the gateway station in the N +7 th frame. The method comprises the steps that an air interface RB is established and configured with 10-19 uplink initial sending time slots of terminals, uplink scheduling time slots of the terminals on a tester side are configured at 10-19, and 2-down-4 configuration is adopted, namely the terminals need to continuously send 4 uplink bursts when the sending time slots arrive after receiving one uplink scheduling.
For example, the terminal receives the uplink scheduling matched with the USF allocated to the terminal in the nth frame, and according to the calculation result of the parameters configured by the air interface, the terminal needs to start to continuously transmit 4 uplink bursts in 2 timeslots of the (N + 3) th frame, and meanwhile, the terminal can continue to receive downlink in the (N + 1) th and (N + 2) th frames, and continuously transmit the uplink scheduling to the terminal in the downlink by using 10 to 19 timeslots of the (N + 1) th frame and the (N + 2) th frame. Since the terminal receives uplink scheduling in the nth frame, the N +1 frame, and the N +2 frame, according to the USF _ DELAY and the number of air interface long DELAY frames, the terminal will continuously send 12 uplink bursts from the 2 timeslot of the N +3 frame, and send the first 2 timeslots that will cover the 32 timeslots, the N +3 frame, the N +4 frame, and the N +5 frame after the N +3 frame. With this arrangement, the theoretical rate is (296 × 12)/(6 × 0.06) ═ 9.867 kbit/s.
It can be seen that the two scheduling methods adopted in fig. 2 and fig. 3 are different in that the uplink initial transmission positions of the terminals are different, fig. 2 corresponds to terminal uplink initial time slot configurations of 0 to 9, and fig. 3 corresponds to terminal uplink initial time slot configurations of 10 to 19. Although the parameters are different, the theoretical rates are all 9.867Kbit/S, and the requirement that the handheld terminal needs to support 9.6Kbit/S for the satellite data service is met. The method provided by the embodiment is proved to be capable of coping with different test scenes only by setting certain script parameters and numerical values thereof, so that repetitive work can be reduced, and the maintenance efficiency is also improved.
In the method provided by the embodiment of the invention, the terminal tester receives the script parameters sent by the script, stores and uses the script parameters to configure the configurable test case, establishes the spot beam and sends the broadcast information to the terminal, and schedules according to the configured configurable test case after receiving the packet domain service information sent by the terminal. Maintenance efficiency can be increased, and repetitive work can be reduced.
Generally, before the terminal initiates the service of the sub-area, it is necessary to access the network, so before the step of receiving the service information of the packet area sent by the terminal, the method further includes: (1) and receiving a network access request sent by the terminal. After receiving the broadcast information sent by the main processing module tester 1 of the tester, the terminal can prepare for network access, and the network access process generally includes that the terminal first sends a network access request to the terminal tester. (2) And configuring network access information according to the network access request. And after receiving the network access request, the terminal tester configures network access information according to the network access request to complete network access preparation work at the terminal tester side. (3) And sending the network access information to the terminal. And after completing the network access preparation work, the terminal tester sends the network access information to the terminal, and the terminal completes the network access work at the terminal side according to the network access information, so that the network access work is completed. In the method provided by the embodiment of the invention, the terminal needs to perform network access work before initiating the packet domain service, and the terminal initiates the packet domain service after the network access is successful. After the terminal is started and accesses the network, the Packet domain service is initiated, and after the context activation of a PDP (Packet Data Protocol) is successful, the Packet domain service is maintained.
In the aspect of scheduling processing, the tester needs to calculate the uplink initial transmission position and the uplink end position of the terminal after each scheduling, so as to ensure that the uplink scheduling of the terminal is not performed when the terminal is transmitting. And when the terminal is at the receiving moment, scheduling as much as possible is ensured so as to achieve the maximum rate of uplink transmission of the terminal. An iperf tool may be used for data transmission, and the method further includes: TCP (Transmission Control Protocol) data transmitted from the terminal is received using the iperf tool. The iperf tool is a network performance testing tool. The Iperf tool can test the maximum TCP and UDP bandwidth performance, has various parameters and UDP characteristics, can be adjusted as required, and can report bandwidth, delay jitter, and packet loss. An iperf tool is used for terminal test and terminal test respectively, the terminal tester is used as a server side, the terminal is used as a client side, TCP data is sent to a server where the terminal tester is located at the terminal by the iperf tool, and the real-time rate is kept at 7.6-8.0 Kbit/S. According to the method provided by the embodiment of the invention, the terminal and the terminal tester both use an iperf tool to complete transmission of TCP data.
Because the rate calculation adopted by the iperf tool is the dead load rate after the TCP/IP head is removed, the real air interface rate cannot be calculated, and the theoretical 9.866Kbit/S is calculated by the air interface rate. Therefore, the method includes the following steps that the terminal test transmission rate is counted through a Media Access Control (MAC) layer on the terminal tester side: counting the total uplink packet number by using the MAC layer counting terminal, and calculating the transmission rate; the total uplink packet number is the total number of uplink data packets sent by the terminal at the preset frame number. Generally, the MAC layer statistics terminal is disposed at the terminal tester side, and after counting the total uplink packet number, the transmission rate can be calculated according to the following equation: rb ═ (N × L)/(F × 0.06); wherein rb is a transmission rate, N is a total uplink packet number, L is a payload length of each data packet, and F is a preset frame number.
For example, the MAC layer statistics terminal counts the total number of uplink data packets sent in 250 frames. Through statistics, the total number of uplink packets sent by the terminal in 250 frames is 500 packets, and the payload length of each packet is 296 bits. Corresponding to the formula given above, the total uplink packet number N is 500, the payload length L of each packet is 296, the preset frame number F is 250, and the formula given above is substituted, so that the transmission rate rb (500 × 296)/(250 × 0.06) ═ 9866.67bit/S (9.86667 Kbit/S) satisfies the theoretical rate of 9.6 Kbit/S. The method provided by the embodiment of the invention counts the transmission rate of the terminal test through the MAC layer at the terminal tester side.
The terminal tester receives script parameters sent by a script, stores and uses the script parameters to configure a configurable test case, establishes a spot beam and sends broadcast information to a terminal, and schedules according to the configured configurable test case after receiving packet domain service information sent by the terminal; before initiating the packet domain service, the terminal also needs to perform network access work, and after the network access is successful, the terminal initiates the packet domain service; the terminal and the terminal tester both use an iperf tool to complete transmission of TCP data; and counting the transmission rate of the terminal test through an MAC layer at the side of the terminal tester. Maintenance efficiency can be increased, and repetitive work can be reduced.
