Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
The embodiment of the invention discloses a method for processing link information, which aims to solve the problem that in the prior art, under the condition of busy voice service, air interface resources are collided, and the link information cannot be reported to a scheduling center.
In the embodiment of the invention, the main application scene is in a PDT or DMR emergency dispatching system, and the system can comprise a calling terminal, a plurality of link machines and a dispatching center. The calling terminal can comprise a digital interphone, an automobile-mounted station and the like and is used for carrying out information interaction with the dispatching center.
Because a narrow-band communication mode with low speed is adopted in the PDT or DMR communication system, the air interface is an air interface and is used for defining the use frequency and the bandwidth of a wireless channel, and the PDT or DMR system uses a Time Division Multiple Access (TDMA) technology with two time slots, and the bandwidth is 12.5 KHz. When the voice service is busy, the voice service occupies the air interface resource, so that the link information cannot be reported to the scheduling center.
Therefore, embodiments of the present invention provide a method, an apparatus, and a system for processing link information, to solve the above problem. The technical solution of the present invention will be described in detail below.
Referring to fig. 1, an embodiment of the present invention discloses a method for processing link information, which is applied to a first link machine in a wireless link system, where the first link machine is connected to a terminal, and the method includes:
s101, receiving first voice data sent by the terminal through a set channel, and judging whether the first voice data contains a voice tail frame, wherein the voice tail frame is used for representing the end of a voice service of the terminal;
in the embodiment of the invention, the terminal is connected with the first link machine, and when the terminal performs the voice service, the terminal sends the first voice data to the first link machine through the set channel, wherein the set channel is an empty channel occupied by the terminal when the terminal uses the voice service.
The first voice data may be data generated when the terminal communicates with the first link machine while performing a voice service. The terminal can include a voice frame, when the terminal uses a voice service, the voice frame is obtained after the voice audio is compressed and encoded, and the first voice data including the voice frame is sent to the first link machine according to a preset time interval through a set channel. Wherein, the preset time interval is one frame of 60ms, and the deviation is not more than 2.5 ms.
In the embodiment of the present invention, the first link machine is a device connected to a terminal, which may be a calling device, and when the terminal finishes communication with other terminals using a voice service, the first voice data carries a voice end frame to indicate the end of the voice service. The specific form of the voice end frame may be a Link Control termination frame (Link Control Terminator), which is an end flag of the voice service.
Determining whether the first voice data includes a voice end frame may include parsing the first voice data to obtain a data frame, determining whether the data frame is a link control termination frame, and if so, determining that the first voice data includes the voice end frame.
S102, if the voice tail frame is contained, packaging link information into a link frame;
and if the first voice data contains the voice tail frame, performing encapsulation operation on the link information to obtain a link frame.
The link information may include key reporting information such as GPS location information and neighbor information.
S103, attaching the link frame to the voice tail frame to obtain second voice data, and sending the second voice data to a next link machine through the set channel.
And after the voice tail frame, attaching the link frame to obtain second voice data, and sending the second voice data to a next link machine. Wherein the next link machine refers to the nearest link machine connected with the link machine.
Specifically, after the voice end frame is sent to the next link machine, the link frame is sent to the next link machine through a preset channel. Of course, the time interval of transmission is also a preset time interval.
It should be noted that, in the PDT or DMR wireless link system, multiple link machines are distributed, the link machine closest to the terminal first receives the voice frame transmitted in the air interface and sends the voice frame to an adjacent link machine, and the link machine receiving the voice frame sends the voice frame to an adjacent link machine, so that multiple link machines will receive the voice frame transmitted in the air interface and send out the voice frame in sequence. The link frame can be reported to the dispatching center through the link machine connected with the communication center, so that the dispatching center can analyze the link information.
It should be noted that, in the PDT or DMR protocol, after the voice service is finished, the terminal sends at least one voice tail frame. When the terminal sends a plurality of voice tail frames, the first link machine takes the first voice tail frame as the time point when the current voice service is ended after receiving the first voice tail frame, and then sends the link frame of the first link machine at the following preset time interval after sending the first voice tail frame.
Therefore, after the voice service is finished, the link frame containing the link information of the first link is added to the next link machine, other channels in an air interface are not used for independently transmitting the link information, and air interface resources are saved. Therefore, even when the traffic is busy, the link information can be transmitted, and the stability of the system is further improved. In addition, due to the mode, the dispatching center can obtain the link information of the plurality of link machines without actively issuing the query command, and secondary collision is avoided.
Preferably, the color code of the link frame is different from the color code of the speech end frame.
In the embodiment of the invention, the color codes of the link frame and the voice tail frame are different. The setting can avoid identifying the link frame as the voice service for processing, causing redundant calculation and increasing unnecessary expenditure.

S203, if the link frame is determined to exist, reporting the link frame to the dispatching center, and sending the voice data to a next link machine.
If the voice data contains the voice tail frame, the voice service of the terminal is proved to be ended, and whether the link frame is contained after the voice tail frame is determined. The link frame packet contains link information used to characterize a state of a link machine. The link information may include key reporting information such as GPS location information and neighbor information.
If the link frame is contained, the link frame is uploaded to a scheduling center, so that the scheduling center analyzes the link frame to obtain link information.
And, the voice data is continuously transmitted to the next link machine.
It can be understood that, at this time, the link frame in the voice data may also be removed, and the voice data with the link frame removed may be sent to the next link machine.
It can be understood that the voice data transmitted between the link machines are all transmitted through a set channel in the air interface, and the set channel is a channel dedicated to the transmission of voice services in the air interface.

S302, when the next link machine is connected with the dispatching center, the link machine reports the link frame to the dispatching center;
and S303, the dispatching center receives and analyzes the link frame to obtain the link information.
If the link machine is connected with the dispatching center, the link frame is reported to the dispatching center, and the dispatching center analyzes the link frame to obtain link information.
