Description

Method, system, control device and terminal for multi-channel collision-free reporting of GPS data

Technical field

The present invention relates to the field of communication technology, and more specifically, to a method, system, control device and terminal for multi-channel collision-free reporting of GPS data.

Background technique

PDT (Public Digital Trunking) police digital trunking standard has the characteristics of clear voice, efficient spectrum efficiency, long communication distance, strong anti-interference ability, and rich voice and data services. The current method adopted by the PDT data cluster system to obtain GPS location information is a combination of periodic pull-up of the auxiliary control channel and active reporting of the dedicated GPS channel.

Under the current PDT system, the principle of GPS cycle pull-up is that MS (Mobile Station, mobile station) waits under the control channel while receiving D_POLL signaling issued by adjacent time slots. D_POLL signaling carries 24bit mobile station air interface address , Pull up the GPS data of the specified MS, which means that when the user expects to subscribe more frequently, the number of MSs that can be subscribed is less. For example, if the user expects to subscribe for 12s, the number of MSs that can be subscribed is only 200.

The current GPS auxiliary control pull-up scheme, because the MS is waiting on the control channel while receiving the D_POLL signaling issued by the adjacent time slot of the control channel, it is equivalent to the 60ms period for the terminal to report a packet of GPS data. In the actual take-out process, most users subscribe to MS with a reporting period of 12s and 30s, which limits the number of MS subscriptions and causes users to have idle carrier frequencies, but cannot expand GPS auxiliary control resources. In order to solve this problem, the existing solution is to introduce the function of multiple control channels through the control device. The user can configure multiple control channels and corresponding auxiliary control channels for the control device to achieve the purpose of expanding GPS auxiliary control resources, but For users, this method is equivalent to occupying an unnecessary control channel, and the channel resource utilization rate is low.

The best mode of the invention

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

1, which is a schematic flowchart of Embodiment 1 of a method for multi-channel collision-free reporting of GPS data provided by the present invention. This method can be applied to cluster communication systems, such as PDT systems.

Specifically, as shown in FIG. 1, the method for multi-channel collision-free reporting of GPS data includes the following steps:

Step S1. The control device receives the original activation signaling sent by the dispatching station when issuing the subscription, and modifies the original activation signaling according to a preset rule, so that the terminals with the same subscription period are grouped together.

In the embodiment of the present invention, the control device may be a base station or a control center.

Further, step S1 includes the following steps:

Step S101: The control device obtains the subscription period and subscription sequence of all terminals, and allocates the same characteristic value to the terminals with the same subscription period.

Step S102: The control device sequentially assigns reporting numbers to the terminals according to the subscription sequence of the terminals having the same subscription period.

For example, if there are N terminals with the same subscription period, the N terminals are sequentially assigned a reporting number of 0 to N-1 according to the subscription order of the N terminals.

The characteristic value is used to identify the group attribute of the terminal, that is, due to the modification effect of the control device, all terminals with the same subscription period have the same characteristic value.

After the control device completes the modification of the original activation information, it sends the modified activation signaling to the terminal.

In the embodiment of the present invention, the modified activation signaling includes a characteristic value used to uniformly code the terminals of the same subscription period at the first level. The characteristic value is generally 8 bits and has a maximum of 256, which is allocated, released and changed by the control device. It also includes a report number assigned to different terminals under the same characteristic value, and the report number is used for the terminal to identify when to jump to the designated GPS service channel.

In the present invention, a batch of terminals with the same subscription period are grouped according to the characteristic value, and each terminal in the same characteristic value group is distinguished according to the report number allocated by the control device, thereby using the characteristic value + report number to assign the second terminal to the terminal. Identity, effectively saving 24bit terminal air interface address to 12bit. In order to illustrate the division of groups, refer to Figures 3a and 3b.

Fig. 3a is a schematic diagram of the original reporting queue of a certain batch of terminals, and Fig. 3b is a schematic diagram of a new reporting queue grouped according to characteristic values.

As shown in FIG. 3b, C1 is a feature value used to indicate a 3s subscription period, C2 and C3 are feature values used to indicate a 30s subscription period, and C4 is a feature value used to indicate a 60s subscription period. It can be seen from Figure 3a that the subscription period of terminal M1 is 3s, the subscription period of terminals M2~M18 is 30s, and the subscription period of terminals M19~M22 is 60s; therefore, after grouping, terminal M1 is a group, M2~M18 form a group, and terminals M19~M22 form a group.

Step S2. The control device issues the first pull-up signaling to the terminal in the adjacent time slot of the control channel to instruct the terminal to jump to the designated GPS service channel according to the first pull-up signaling.

In the embodiment of the present invention, the first pull-up signaling includes a designated GPS service channel number, a designated GPS service time slot number, a waiting number of skipped time slots, and a private time slot count value.

In the embodiment of the present invention, the first pull-up signaling is used to instruct the addressed terminal to report GPS data. Among them, the designated GPS service channel number is used for the terminal to identify and jump to the same channel as the number. For example, for a certain characteristic value of N terminals under X (a group), the designated GPS service channel number in the first pull-up signaling is CH1, the number of waiting time slots for skipping is K, and the count value of private time slots is T . After receiving the first pull-up signaling, the N terminals with the characteristic value X recognize CH1, K, and T, and jump to the designated GPS service channel CH1, and at the same time, judge themselves according to the number of jump timeslot waiting K In order to achieve the purpose of avoiding collisions, and according to the private time slot count value, it determines the time slot when it reports GPS data after jumping to the designated GPS service channel CH1.

Step S3: After the terminal with the same subscription period jumps to the designated GPS service channel, the control device sends a second pull-up signaling downward, so that the terminal reports GPS data according to the second pull-up signaling.

In the embodiment of the present invention, the first pull-up signaling is the pull-up signaling issued by the control device on the control channel, and the second pull-up signaling is the pull-up signaling issued by the control device on the control channel.

2, which is a schematic flowchart of Embodiment 2 of a method for multi-channel collision-free reporting of GPS data provided by the present invention.

As shown in FIG. 2, the method for multi-channel collision-free reporting of GPS data in this embodiment includes the following steps:

Step 21: The terminal modifies its own feature value and reporting sequence number on the auxiliary control channel according to the feature value and reporting sequence number allocated by the control device to obtain a new feature value and new reporting sequence number.

Step 22: The terminal receives the first pull-up signaling issued by the control device in the adjacent time slot of the control channel, and jumps to the designated GPS service channel according to the first pull-up signaling.

Step S22 includes the following steps:

Step S221: The terminal analyzes and processes the first pull-up signaling, and extracts the designated GPS service channel number, the designated GPS service time slot number, the number of waiting timeslots for jumping, and the count value of the private time slot.

Step S222: The terminal jumps to the designated GPS service channel corresponding to the designated GPS service channel number according to the designated GPS service channel number.

Further, step S22 also includes:

Step S223: The terminal performs a summation operation on the private time slot count value extracted from the first pull-up signaling, the number of waiting time slots for the jump, and its own reporting number to obtain a new time slot, which is the terminal reporting GPS The time slot for reporting data.

In the embodiment of the present invention, the first pull-up signaling is used to instruct the addressed terminal to report GPS data. Among them, the designated GPS service channel number is used for the terminal to identify and jump to the same channel as the number. For example, for a certain characteristic value of N terminals under X (a group), the designated GPS service channel number in the first pull-up signaling is CH1, the number of waiting time slots for skipping is K, and the count value of private time slots is T . After receiving the first pull-up signaling, the N terminals with the characteristic value X recognize CH1, K, and T, and jump to the designated GPS service channel CH1, and at the same time, judge themselves according to the number of jump timeslot waiting K To achieve the purpose of avoiding collisions, and according to the private time slot count value T and the number of waiting time slots K to determine when it jumps to the designated GPS service channel CH1, it determines the time when it reports GPS data. Time slot.

The specific determination process is as follows: after the terminal jumps to the respective designated GPS service channel, it records the private time slot count value T in the first pull-up signaling, the designated service channel number CH1 and the number of waiting time slots for the jump K, and The private time slot count value T, the number of hop time slots waiting K, and its own report number are summed, and the sum of the three is the time slot that the terminal should report when reporting GPS data on the designated GPS service channel.

Step 23: After jumping to the designated GPS service channel, the terminal receives the second pull-up signaling issued by the control device, and reports GPS data according to the second pull-up signaling.

In the embodiment of the present invention, the second pull-up signaling carries the current time slot when GPS data is reported.

Further, step S23 includes:

Step S231: The terminal extracts the current time slot according to the second pull-up signaling.

Step S232: The terminal judges whether the condition for reporting GPS data is satisfied according to the current time slot, if yes, it reports its own GPS data, if not, it jumps back to the control channel.

Among them, step S232 is specifically implemented in the following manner:

The terminal compares its own reporting time slot with the current time slot; if the reporting time slot is equal to the current time slot, it will report GPS data; if the reporting time slot is less than the current time slot, it will continue to wait until it reaches the current time slot and report GPS data ; If the reported time slot is greater than the current time slot, jump back to the control channel.

In the embodiment of the present invention, the GPS data reported by the terminal on the designated GPS service channel includes the reporting period of the terminal and the reporting time slot of the terminal.

The specific jump and GPS data report are shown in Figure 4. In Figure 4, C_DPOLL is the first pull-up signaling, and NUM represents the field of the private time slot count value. As shown in Figure 4, the terminal M2 locks the service channel, and Jump to the designated GPS service channel. When the second pull-up signaling (P_DPOLL) is received, the corresponding judgment is made. It can be seen from Fig. 4 that the terminal M2 meets the reporting conditions and reports GPS data.

When a large number of terminals are registered on the same base station, when the GPS data of all terminals can be obtained by implementing the method of multi-channel collision-free reporting of GPS data of the present invention, only the first pull-up signaling (C_DPOLL) needs to be issued on the auxiliary control channel. ), the first pull-up signaling carries different characteristic values and designated channel numbers. The first pull-up signaling can reach terminals in different groups, and the terminals will jump to their designated GPS services in the order in which the reporting numbers are configured. Channel and report GPS data. As shown in Fig. 5, the updated reporting timing, at the same time (NUM=104), terminal M3 and terminal M19 respectively report GPS data on channel CH1 and channel CH2, effectively increasing the capacity of the system to report GPS data.

Further, in the method for multi-channel collision-free reporting of GPS data in the embodiment of the present invention, when the reporting period of the terminal needs to be modified, the characteristic value and the reporting number of the terminal need to be modified. However, the terminal in the embodiment of the present invention receives no matter on the auxiliary control channel. When the first pull-up signaling is reached or the second pull-up signaling is received on the designated GPS service channel, the characteristic value group information of the corresponding terminal reported in the current time slot can be modified in real time, and the EN (enable switch) carried in the identification signaling can be modified in real time. ) Field (the EN field is used to control whether to change the characteristic value of the terminal), according to the identification of the identified EN field to modify or not modify its own characteristic value, if the EN field is marked as modified, according to the new The eigenvalue of, modify its own eigenvalue to the same eigenvalue as the new eigenvalue carried in the signaling, and modify the report number accordingly. Therefore, in the embodiment of the present invention, when the reporting period of the terminal needs to be modified, there is no need to reissue the activation signaling.

In addition, it should be noted that, in the method for multi-channel collision-free reporting of GPS data in the embodiment of the present invention, when the first pull-up signaling is issued in the adjacent time slot of the control channel, the time slot of the control channel can also perform another time slot at the same time.
