Detailed Description
In order to make the objects, technical solutions and advantages 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 obvious 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.
Aiming at the problem that the prior art can not ensure the communication quality of group calling users in a broadband trunking system, the invention provides a novel broadband trunking call processing method to solve the problem that the data reception of important group members in a trunking system can not be ensured under the condition of poor signal conditions.
Fig. 2 is a schematic flow diagram of a broadband trunking call processing method provided by the present invention, and as shown in fig. 2, a corresponding execution main body is a terminal, which includes:
in a broadband trunking system, a terminal (generally, a dispatcher or a user) initiates a group call, at this time, a plurality of users usually participate in the group call at the same time, and all users participating in the group call are called group users and generally identified as being in the same group; users in the same Group do not necessarily belong to the same cell, but in most cases, multiple users belong to the same cell, in the same cell, all Group members share the same Downlink data transmission Channel, i.e., PDSCH (Physical Downlink Shared Channel), the base station transmits Downlink data on the PDSCH, and all Group members in the cell use the same G-RNTI (Group-Radio Network temporary Identity) to retrieve scheduling information of the base station, thereby receiving the same Downlink transmission data.
According to the specification of a broadband cluster air interface protocol, a terminal receives a PDSCH scrambled by a G-RNTI, namely group calling, and the terminal does not support the adoption of ACK/NACK reporting, namely, under the group calling service, a user cannot feed back the receiving condition of self downlink data through ACK/NACK, and a base station cannot know the data receiving condition of the group calling user in the range.
after receiving the downlink group call data, the terminal user measures the quality of the downlink channel to obtain the measurement result of the quality of the downlink channel under the current receiving condition, and then maps the measurement result into the index value of the downlink channel according to the rule.
A terminal user can judge whether the processing capacity of the terminal user needs to be reported to a base station in real time according to the mobile access condition of the terminal user in the coverage area of the base station, when the preset reporting condition set by a system is met, the terminal triggers a reporting flow, and the measured result of the measured downlink channel quality is reported to the base station through a specific data format of random access;
after receiving the feedback information of the terminal user, the base station optimizes the downlink group calling scheduling according to the specific feedback information, and adjusts the modulation mode, power or directional beam of the downlink data scheduling by referring to the reported measurement result of the downlink channel quality so as to enhance or reduce the quality of the received signal of the group calling user.
The invention feeds back the communication quality of the user to the base station implicitly through the terminal reporting capability of the group calling user, so that the base station can flexibly adjust the scheduling of the downlink group calling in time, can cope with the change of the communication environment of the group calling user in various scenes, and has higher practicability.
Based on the above embodiment, step 101 includes:
retrieving downlink scheduling information of the base station by adopting a group calling radio network temporary identifier G-RNTI;
and receiving the downlink group call data on the same Physical Downlink Shared Channel (PDSCH) based on the downlink scheduling information.
Specifically, all terminals in the group calling service use the same G-RNTI to retrieve downlink scheduling information of the base station, and the terminals receive a PDSCH scrambled by the G-RNTI and receive downlink group calling data transmitted by the base station on the PDSCH.
Here, because ACK/NACK reporting is not supported, that is, in the group call service, a user cannot feed back the downlink data reception condition of the user through ACK/NACK, and the base station cannot know the data reception condition of the group call user in the range.
The invention acquires the mechanism that the group calling user terminal can not feed back the self state by analyzing, thereby increasing the terminal capability reporting information in the specific format at the terminal side to enable the base station to acquire the downlink data receiving condition of the group calling user.
Based on any of the above embodiments, step 102 includes:
measuring packet loss rate and/or downlink signal-to-noise ratio of the downlink group call data to obtain a downlink channel quality measurement result;
and mapping the downlink channel quality measurement result according to a preset rule to form the downlink channel index value.
Wherein the mapping the downlink channel quality measurement result according to a preset rule to form the downlink channel index value comprises:
mapping a signal to interference plus noise ratio (SINR) of a first preset interval to an index value of a second preset interval based on a Channel Quality Indicator (CQI) mapping table to obtain a downlink signal to noise ratio index value;
or mapping the SINR of the first preset interval to an index value of a third preset interval based on a Modulation and Coding Strategy (MCS) mapping table to obtain the index value of the downlink signal-to-noise ratio;
and gradually increasing the index value of the packet loss rate by 1 according to a preset increasing percentage by taking a preset percentage as a starting point to obtain the index value of the packet loss rate.
Specifically, when a terminal user performs a group call service, a downlink channel quality measurement result is obtained by measuring a packet loss rate and/or a downlink signal-to-noise ratio, and the downlink channel quality measurement result is mapped into an index value according to a preset rule, where the specific index value range may be multiple, and generally includes 0 to 15, 0 to 31, and 0 to 63.
The downlink Signal-to-Noise Ratio mapping criterion adopted by the invention refers to a CQI (Channel Quality Indication) mapping table, and maps SINR (Signal to Interference plus Noise Ratio) in the range of [ -5,20+ ] to an index value of 0-15 in a first preset range, or refers to an MCS (Modulation and Coding Scheme) mapping table, and maps SINR in the range of [ -5,20+ ] to an index value of 0-31 in a second preset range. The packet loss rate starts at a preset percentage of 10%, i.e., 10% → 0, and increases by 1 for a packet loss rate index value that is 20% higher than the preset percentage per liter.
Here, when the group call service is reported from the beginning to the possible time, the ue will continuously update the statistics and index values for standby.
The user terminal of the invention represents the quality of the downlink signal by measuring the common downlink signal-to-noise ratio or the packet loss rate, and maps the ACK/NACK information and the downlink channel quality as the index value, thereby having the characteristics of intuition and convenient calculation and being convenient for the terminal to report the index value.
Based on any of the above embodiments, step 103 includes:
if the packet loss rate is judged to be greater than a preset threshold or exceed a preset time, triggering a reporting process;
obtaining a G-RNTI R2MAC CE sent in a first uplink data or signaling packet after the G-RNTI of the randomly accessed Msg3 or cluster listened to service;
and determining to adopt a first reserved data interval in the G-RNTI R2MAC CE for reporting the downlink signal-to-noise ratio index value, and/or adopt a second reserved data interval in the G-RNTI R2MAC CE for reporting the packet loss rate index value.
Specifically, after the index value is obtained, the user terminal counts whether the packet loss rate exceeds a preset threshold or continuously exceeds a preset time according to a preset reporting condition set by the system, and if the preset reporting condition is met, the user terminal triggers a reporting process.
Generally, triggering and reporting should be performed by sending a G-RNTI R2MAC CE in the Msg3 through random access, or by obtaining a G-RNTI R2MAC CE sent in a first uplink data/signaling packet after the G-RNTI of the cluster listened service.
The data format of the existing G-RNTI R2MAC CE is shown in fig. 1, and is 24 bits in total, where G-RNTI occupies 16 bits of data in Oct1 and Oct2 in total, bit0 remaining in Oct3 is a terminal capability indication bit, 0 is taken to indicate a blind detection capability type 1 terminal, 1 is taken to indicate a blind detection capability type 2 terminal, bit1 is an inter-frequency networking gap conversion indication, and 6R remaining bits are reserved bits and are set to 0 by default.
In order to realize terminal capability reporting in the G-RNTI R2MAC CE, it is necessary to plan the reserved 6 rs, and allocate 6 bits to the packet loss ratio and the downlink signal-to-noise ratio (i.e. signal quality), the optimized G-RNTI R2MAC CE data format is shown in fig. 3, when it is necessary to report the signal quality and the packet loss ratio simultaneously, 4 bits are used for the signal quality index, 2 bits are used for the packet loss ratio index (Option 1 in fig. 3), and if it is only necessary to report the signal quality, 6 bits are all used for the signal quality index (Option 2 in fig. 3).
The invention optimizes and modifies the existing uplink control unit on the basis of not damaging the data format of the existing uplink control unit, and the influence on the existing protocol is reduced to the minimum.
Fig. 4 is a second flowchart of the broadband trunking call processing method provided by the present invention, and as shown in fig. 4, the corresponding execution subject is a base station, which includes:
the trunking base station receives the group calling requirement sent by the terminal which carries out the group calling service in the coverage area, and because all terminal users in the cell use the same G-RNTI to retrieve the scheduling information of the base station, the terminal users all receive the downlink group calling data sent by the base station on the same PDSCH.
The terminal can judge whether the processing capacity of the terminal needs to be reported to the base station in real time according to the mobile access condition of the terminal in the coverage area of the base station, and when the preset reporting condition set by the system is met, the terminal triggers a reporting flow and reports the measured result of the measured downlink channel quality to the base station through a specific data format of random access.
After receiving the feedback information of the terminal user, the base station optimizes the downlink group calling scheduling according to the specific feedback information, and adjusts the modulation mode, power or directional beam of the downlink data scheduling by referring to the reported measurement result of the downlink channel quality so as to enhance or reduce the quality of the received signal of the group calling user.
The invention reports the current terminal processing capability to the base station by the terminal actively, so that the base station flexibly adjusts the downlink scheduling index of the group call service, ensures the communication quality of the group call user and effectively saves downlink resources.
Based on the above embodiment, step 202 includes:
receiving a downlink signal-to-noise ratio index value and/or a packet loss rate index value reported by the terminal;
based on the downlink signal-to-noise ratio index value and/or the packet loss ratio index value, adjusting a downlink modulation and demodulation mode and/or a downlink power value of the downlink group call data to obtain modified scheduling information;
and scheduling the terminal based on the modified scheduling information.
Specifically, after receiving information fed back by the group calling user through the G-RNTI R2MAC CE, the trunking base station performs optimization processing on the group calling scheduling according to specific numerical values of the feedback information, and the base station adjusts a modulation mode, power or directional beam of downlink data scheduling by referring to reported signal quality and packet loss rate, so as to enhance or reduce the received signal quality of the group calling user.
By the broadband cluster call processing method provided by the invention, under the condition that the signal quality of the group call user is better, the base station can adopt a higher-order modulation mode or reduce downlink power, and downlink air interface resources can be fully saved.
In the following, an embodiment of the present invention is described with reference to an actual wideband trunking application scenario, as shown in fig. 5, in the scenario, three users reside in a cell a, when a group call service starts, a base station a provides the same group call data on a Downlink Shared Channel for a UE _ A, UE _ B, UE _ C, and a UE _ A, UE _ B, UE _ C retrieves scheduling information of the base station a using the same G-RNTI, and if a PDCCH (Physical Downlink Control Channel) scrambled with a group user G-RNTI as an identifier is retrieved in a TTI (Transport Time Interval), decodes a TB (Transport Block) of a designated DL-SCH (Downlink Shared Channel) Channel to receive data. Because of the trunking group call service, the terminal will not process HARQ (Hybrid Automatic Repeat reQuest) flow, when UE _ a moves to the edge of the cell, its air interface signal becomes bad, and it cannot correctly demodulate to the static scheduling information of base station a, at this time, the terminal capability reporting flow is triggered, UE _ a reports the measurement information to base station a on G-RNTI R2MAC CE, base station a corrects the static scheduling information according to the reported data to ensure the transmission of UE _ a, when UE _ a returns to the cell center position, base station a does not receive any UE capability report for a long time, and also adjusts the static scheduling information according to the rule. The above scenario completion is that the implementation flow is shown in fig. 6, and includes:
step 1: the group call service starts, and the base station a transmits downlink group call data for users of the same cluster group in the cell. Users in the cluster group can use the same G-RNTI to retrieve the scheduling information of the base station A, if a PDCCH scrambled by taking the G-RNTI of the group user as an identifier is retrieved in a certain TTI, the TB of a designated DL-SCH channel is decoded to receive data;
step 2: when the UE _ a moves to the edge of the cell a, the received signal strength becomes poor, the static scheduling information of the base station a cannot be correctly demodulated, and the packet loss rate significantly increases, at this time, the UE capability reporting process is triggered: the triggering condition for reporting depends on the downlink packet loss rate counted by the UE _ a, in this embodiment, the packet loss rate reaches 50% and lasts for 500ms as the triggering condition, when the condition is reached, the UE _ a reports the UE capability, the reported data is the downlink signal quality counted by the UE, and the signal to interference plus noise ratio SINR value is used, which can reflect the comprehensive situation of the downlink signal strength and the interference situation. In order to adapt to the format of a reported data entity, UE maps the counted downlink signal quality into an index value of 0-31 in a partition mode;
and step 3: after the reporting condition is triggered, the UE sends G-RNTI R2MAC CE in Msg3 through random access, or sends G-RNTI R2MAC CE through a first uplink data/signaling packet after the G-RNTI of the cluster listened service is obtained; in order to realize reporting on the G-RNTI R2MAC CE, the UE _ A fills the downlink signal quality index value in the remaining 6 bits on the third Oct of the G-RNTI R2MAC CE, so that the signal quality of the UE _ A reports the G-RNTI R2MAC CE in the reporting information along with the UE capability to the cluster base station A;
and 4, step 4: after receiving the information fed back by the UE _ A through the G-RNTI R2MAC CE, the trunking base station A corrects the group calling scheduling according to the specific numerical value of the feedback information, and the base station A refers to the reported signal quality index to calculate the maximum MCS which can be adopted by the UE _ A to successfully demodulate the data at the moment or the power increased by the base station on each RE can enable the UE _ A to successfully demodulate the data. After the calculation result is obtained, the base station can adjust the modulation mode and power of downlink data scheduling according to the calculation result so as to enhance or reduce the quality of the received signal of the group calling user; the modulation and demodulation mode MCS modification and downlink power value improvement can be used in a matched manner or can be used independently;
and 5: the base station A adopts the modified scheduling information to schedule the group call users in the cell A;
step 6: when UE _ A moves to the center of the cell, the packet loss rate is reduced, and the reporting condition of the UE capacity can not be triggered any more;
and 7: when the base station does not receive any UE capability report for a long time, the existing scheduling information needs to be corrected, and the principle of correction is to gradually reduce the downlink power value of each RE or to improve the modulation and demodulation mode. The modified modulation and demodulation scheme MCS and the boosted downlink power value may be used in combination or may be used independently.
