Description

A kind of non line of sight visual command communication system

[technical field]

The present invention relates to a kind of command system, be specifically related to a kind of non line of sight visual command communication system, belong to public emergent command dispatching system technical field.

[background technology]

At present, traditional voice scheduling machine using method is single, some voice communication systems mainly access and realize different communication systems voice call each other by it, but can not by (on-the-spot audio frequency and video) connecting system of non line of sight wireless digital microwave audio-video transmission system, converse in the individual soldier front end that can not realize various voice communication system and non line of sight wireless digital audio-video transmission system, more can not receive and the image scene showing non line of sight wireless digital audio-video transmission system and pass back, on-the-spot actual conditions cannot be understood, effectively the most efficient command scheduling is carried out to field condition.

Therefore, for solving the problems of the technologies described above, the necessary non line of sight visual command communication system providing a kind of advanced person, to overcome described defect of the prior art.

[summary of the invention]

For solving the problem, the object of the present invention is to provide a kind of non line of sight visual command communication system can inserting different communication terminal digital module groups according to different demand.

For achieving the above object, the technical scheme that the present invention takes is: a kind of non line of sight visual command communication system, it comprises computer, phone of attending a banquet/hand miaow, audio frequency and video dispatching patcher, VOIP phone, mobile phone, Vehicle mounted station/hand platform, public telephone network, inside line and individual soldier's transmitter; Wherein, described computer, phone of attending a banquet/hand miaow are connected in audio frequency and video dispatching patcher; Described VOIP phone is connected in audio frequency and video dispatching patcher by sip server; Described mobile phone, Vehicle mounted station/hand platform, public telephone network, inside line and individual soldier's transmitter are also connected in audio frequency and video dispatching patcher respectively.

Non line of sight visual command communication system of the present invention is set to further: described audio frequency and video dispatching patcher comprises middle control scheduling unit, unit is attended a banquet in this locality, power subsystem, VOIP unit, 2G/3G unit, radio channel unit, outside line TU Trunk Unit, exchange side terminal block and microwave receiving unit.

Middle control scheduling unit of the present invention arranges as follows: system receives first packet, and blind check enters call phase state after measuring code check.If SID frame detected, then enter quiet period state.In call phase state, if continuous several times is without uplink, then enter quiet period state.If quiet period state detects speech frame, then get back to call phase state.Business needs Resources allocation when quiet period is transformed into the call phase, needs to cancel resource when being transformed into quiet period from the call phase.Detect bag size by PDCP, rule out and enter quiet period or call phase, then by PDCCH deexcitation or activation semi-persistent resource.

In this system, the resource distribution mode of scheduling has selection scheduling and non-frequency selection scheduling frequently.Frequently selection scheduling is continuous subcarrier or the Resource Block of UE distribution.Which needs eNodeB to obtain more detailed channel quality information.Select the good Resource Block of mass ratio by subband CQI, improve system availability and UE peak rate.In UL scheduling, selection scheduling is the good Resource Block of UE allocated channel quality frequently, and channel quality is obtained by SINR; Non-frequency selection scheduling is subcarrier or the Resource Block of UE allocation of discrete, and which needs eNodeB to obtain the CQI of full band, can reduce signaling consumption.In UL scheduling, non-frequency selection scheduling is on given frequency band, from the high-end Resource Block available continuously to low side search.When community UE to be scheduled is less, use selection scheduling frequently can produce a large amount of fragments, so preferentially select non-frequency selection scheduling.

For the user data of different QoS, for user k business i is defined as follows priority:

$P_{k,i}^m={\mathrm{\ξ}}_k\frac{{\left[{\mathrm{\μ}}_k^m\left(t\right)\right]}^{\mathrm{\γ}}}{{\left[\stackrel{\‾}{R_{k,i}(t-1)}\right]}^{\mathrm{\β}}}[{\mathrm{\η}}_{k,i}^W{\left(\frac{W_{k,i}\left(t\right)}{T_{k,i}}\right)}^{{\mathrm{\α}}_1}+{\mathrm{\η}}_{k,i}^Q{\left(\frac{Q_{k,i}\left(t\right)}{Q_{k,i}^{\max }}\right)}^{{\mathrm{\α}}_2}]$

The each parameter interpretation of formula is as follows:

ξ _k: user gradation, dynamic configures;

the byte number that user can pass on certain Resource Block RB, channel quality: the information of CQI feedback;

out, windowing calculates the numerical computations of measuring business volume, can with reference to PF algorithm;

γ: 0 or 1, dynamic configures; 0 interval scale does not consider channel quality, and channel quality is considered in 1 representative;

β: can arrange, fairness factor;

time delay correlation factor, dynamic configures;

W _{k, i}(t): first packet time delay (RLC);

T _{k, i}: QoS maximum allowable delay, dynamic configures;

queue length correlation factor, dynamic configures;

Q _{k, i}(t): queue length (byte number, RLC);

maximum permission queue length (byte number, RLC), dynamic configures;

α ₁: 0 or 1, default 1, dynamic configures;

α ₂: 0 or 1, default 1, dynamic configures;

M: user k business i calculating priority level on channel m.

When user k be business i have selected one piece of resource still not time, must continue to select resource, suppose that the priority on n subchannel is calculated as follows:

$P_{k,i}^n={\mathrm{\ξ}}_k\frac{{\left[{\mathrm{\μ}}_k^n\left(t\right)\right]}^{\mathrm{\γ}}}{{\left[\stackrel{\‾}{R_{k,i}(t-1)}\right]}^{\mathrm{\β}}}[{\mathrm{\η}}_{k,i}^W{(\frac{Q_{k,i}^{\′}\left(t\right)}{Q_{k,i}\left(t\right)}\·\frac{W_{k,i}\left(t\right)}{T_{k,i}})}^{{\mathrm{\α}}_1}+{\mathrm{\η}}_{k,i}^Q{\left(\frac{Q_{k,i}^{\′}\left(t\right)}{Q_{k,i}^{\max }}\right)}^{{\mathrm{\α}}_2}]$

M-LWDF algorithm is mainly applicable to real time business, and its priority can be expressed as:

$P_{k,i}^m=\frac{{\mathrm{\ξ}}_k}{T_{k,i}}\frac{{\mathrm{\μ}}_k^m\left(t\right)}{\stackrel{\‾}{R_{k,i}(t-1)}}{W}_{k,i}\left(t\right)$

Wherein, T _{k, i}for the maximum time limit restriction that i-th QoS of survice of user k requires, the δ set in qos requirement _{k, i}for the time delay W of i-th business data packet of user k _{k, i}t () is greater than T _{k, i}probability, that is:

P{W _k，i(t)〉T _k，i}≤δ _k，i

Therefore, for real time business, choose the priority with following form:

$P_{k,i}^m={\mathrm{\ξ}}_k\frac{{\mathrm{\μ}}_k^m\left(t\right)}{\stackrel{\‾}{R_{k,i}(t-1)}}[{\mathrm{\η}}_{k,i}^W\frac{W_{k,i}\left(t\right)}{T_{k,i}}+{\mathrm{\η}}_{k,i}^Q\frac{Q_{k,i}\left(t\right)}{Q_{k,i}^{\max }}]$

For non-real-time service, the priority of definition is as follows:

$P_{k,i}^m=\frac{{\mathrm{\μ}}_k^m\left(t\right)}{\stackrel{\‾}{R_{k,i}(t-1)}}{\mathrm{\η}}_{k,i}^Q\frac{Q_{k,i}\left(t\right)}{Q_{k,i}^{\max }}$

The delay requirement of the data on control channel is very high, and allows the probability of packet loss very low, for this special business, and definition priority:

$P_{k,i}^m=\frac{1}{T_{k,i}}\frac{{\mathrm{\μ}}_k^m\left(t\right)}{\stackrel{\‾}{R_{k,i}(t-1)}}{\mathrm{\ξ}}_k{W}_{k,i}\left(t\right)$
