- the invention relates to the field of digital trunking communication systems, in particular to a method for reporting positioning information and a terminal thereof. Background technique
- Digital trunking communication system is an important branch of mobile communication system, mainly used in professional mobile communication fields, such as government departments, military, police, railway, water conservancy, civil aviation and steel logistics.
- the digital trunking communication system mainly includes a terminal, a base station, and a scheduling subsystem, wherein: the terminal is a main device for the cluster network to interact with the user, and is a terminal device having a cluster service function; the base station completes the access function of the terminal, and is connected to the cluster terminal. And the main equipment of the scheduling subsystem; the scheduling subsystem is the control center of the cluster service, and completes the control and management functions of the terminal cluster service in the service area.
- the digital trunking communication system is a mobile communication system applied to group dispatching command communication. In this paper, the merging of the base station and the scheduling subsystem is referred to as the system side for simplicity.
- the terminal When the system needs to perform scheduling and other operations according to the location information of the terminal, the terminal needs to report its own location information to the system side, such as the current latitude and longitude.
- Digital trunking communication system support
- SWI (Service With Information) signaling is used to transmit location information.
- SWI signaling is a communication protocol of the cluster scheduling system, and is used for transmitting scheduling related messages between each network element.
- the system side requests the terminal to report the location information, the system sends a forward SWI signaling to the terminal to trigger the location request.
- the system sends a reverse SWI signaling to the system side to report the location information to the system.
- the reporting process in the related art when the system side needs to acquire the terminal location information, sends the forward SWI signaling for the location information reporting request to the terminal; Initial positioning, whether the positioning is successful or not, sends reverse SWI signaling within a specified period of time, and identifies whether the current positioning is successful in the body of the message.
- the forward SWI signaling will be retransmitted.
- This method of message transmission increases the possibility of message retransmission, increases the burden of air interface, and the reverse SWI signaling of the positioning failure has no practical significance for the system side, and only increases the air interface burden.
- the air interface burden caused by the positioning information reporting will impact the base station.
- the technical problem to be solved by the present invention is to provide a digital trunking system terminal and a positioning information reporting method thereof, which reduces the air interface burden caused by the positioning information reporting and the impact of the base station.
- the present invention provides a method for positioning information, the method comprising:
- the terminal receives the forward SWI signaling sent by the system side to request the terminal to report the location information.
- the terminal replies to confirm the reverse SWI signaling of the forward SWI signaling to the system side;
- the terminal performs positioning to obtain location information
- the terminal determines whether the location information is valid. When the location information is valid, the location information is reported to the system side by using reverse SWI signaling.
- the method further includes: determining whether it is necessary to continue reporting, and if yes, performing step C, otherwise ending the process.
- the forward SWI signaling carries a reporting policy, where the reporting policy includes a single reporting and a periodic reporting.
- the forward SWI signaling also carries an uplink reporting policy.
- the step B further includes saving the related parameters of the reporting policy.
- the parameters related to the policy include: an upper time point, and/or a start time, an end time, and a reporting period.
- the reporting policy related parameters include setting a working day parameter that is repeatedly reported on each working day.
- the present invention provides a terminal, where the terminal includes a receiving module, a positioning module, and a reporting module, where:
- a receiving module configured to receive a forward direction sent by the system side for requesting the terminal to report the location information
- the SWI signaling, and the reply is used to acknowledge the reverse SWI signaling of the forward SWI signaling to the system side;
- a positioning module configured to perform positioning, and obtain location information
- the reporting module is configured to report the location information to the system side by using reverse SWI signaling when the location information is valid.
- the terminal After the terminal receives the forward SWI signaling on the system side, the terminal immediately replies with a reverse SWI signaling to acknowledge the received command, thereby avoiding retransmission on the system side; The judgment of whether the current positioning information is valid, if invalid, cancels the reporting, thereby reducing invalid interactive signaling.
- the terminal reports its own location information to the system side, it reduces the impact of the air interface burden caused by the location information reporting on the base station.

- FIG. 1 is a flowchart of positioning information reporting according to Embodiment 1 of the present invention.
- FIG. 3 is a block diagram of a terminal of a second embodiment of the present invention. detailed description
- Step 201 The terminal receives the forward SWI signaling sent by the system side, where the forward SWI signaling is used to request to report the positioning information. .
- the present embodiment may carry the reporting policy in the forward SWI signaling, and may include two methods: single reporting and periodic reporting.
- the reporting policy related parameters include time parameters for indicating the reporting time point, including but not limited to: reporting the time point (eg, at which time), or starting time, ending time, and reporting period.
- the report policy related parameters also include the workday parameters for setting the report to be repeated on each working day and not reporting on the rest day.
- Step 202 After receiving the forward SWI signaling, the terminal replies with a reverse SWI signaling to the system side, where the reverse SWI signaling is used to acknowledge receipt of the request.
- the terminal sends a reverse SWI signaling to the system side to acknowledge the received request, and the system side receives the reverse SWI replied by the terminal to stop the retransmission operation. Therefore, the system side is repeatedly sent to the SWI signaling because it does not receive the location information reported by the terminal within a certain period of time.
- the terminal After the terminal replies to the reverse SWI signaling, it also needs to obtain the positioning mode sent by the system side, and confirm that the terminal is required to report a single time or request the terminal to report the timing. If it is reported periodically, this step also needs to save the requesting terminal to save the relevant parameters of the reporting policy.
- Step 203 The terminal performs positioning to obtain location information.
- Step 204 the terminal determines whether the current location information is valid, if it is valid data, step 205 is performed, otherwise, step 206 is performed;
- this step it is determined whether the current location information data is valid data, if the current location If the information data is invalid data, the current report is cancelled, thereby reducing the invalid signaling interaction when the positioning fails.
- Step 205 The terminal constructs its own location information as reverse SWI signaling, and reports it to the system side.
- Step 206 The terminal determines whether to end the positioning according to the report request information. If the report needs to be continued, step 203 is performed; otherwise, the reporting process ends.
- the invalid interaction signaling between the terminal and the system side is reduced, so that the terminal reports its own location information to the system side, and reduces the impact of the air interface burden caused by the location information reporting on the base station.

- the reporting policy-related parameters may be carried in the forward SWI signaling.
- the reporting policy related parameters include time parameters for indicating the reporting time point, including but not limited to: the reporting time point (eg, at which time), or the starting time, the ending time, and the reporting period. In order to meet the scenario, only the workday/restday report is required.

数字集群通讯系统主要包括终端, 基站, 调度子系统, 其中: 终端是 集群网络与使用者交互的主要设备,是具备集群业务功能的终端设备;基站 完成终端的接入功能, 是连集群接终端和调度子系统的主要设备; 调度子 系统是集群业务的控制中心, 完成对服务区内终端集群业务的控制和管理 功能。 数字集群通讯系统是一种应用于集团调度指挥通讯的移动通讯系统。 在本文中, 为了简便将基站和调度子系统合并称为系统侧。
当系统侧需要根据终端的位置信息进行调度等工作时, 需要终端上报 自身位置信息给系统侧, 如当前的经纬度等。 数字集群通讯系统支持通过
SWI ( Service With Information, 调度服务信息 )信令来传递位置信息, SWI 信令是集群调度系统的一种通讯协议, 用于各个网元之间传递调度相关消 息。 当系统侧要求终端上报位置信息时, 系统侧向终端发送一个前向 SWI 信令, 触发定位请求; 终端上报时向系统侧发送一个反向 SWI信令, 将自 身位置信息上报给系统侧。
