Description

Wireless channel configuration method, device, server and system

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a server, and a system for configuring a wireless channel.

Background

The Global System for Mobile Communications (GSM) is the most widespread and the largest Mobile communication System in the world, and will be maintained for a long time in the future, so that the maintenance and updating of the GSM System will be continued. Various functions of the GSM system are implemented, and a conventional evolution mode is to continuously add new features on the basis of basic functions. For example, on the basis of traditional Voice Service (CS) Channel allocation, with the introduction of General Packet Radio Service (GPRS) and Enhanced Data Rate for GSM Evolution (EDGE), the problem that the CS Service and the Data Service (PS) Service share a Radio Channel is brought, and with the subsequent continuous development of some new functional characteristics, the system is continuously added, such as a dynamic-independent Dedicated Control Channel (SDCCH), a single-slot Multi-user Voice Service (VAMOS), and so on.

With the above gradual evolution, the allocation of radio channels is also continuously improving. In GMS systems, the mode of operation in which one channel carries one call is called Full Rate (FR), while the mode in which one channel carries 2 calls is called Half Rate (HR). The bearing capacity of the half-rate channel can be doubled relative to the full-rate channel, so that the investment of wireless carrier frequency is saved, additional carrier frequency capacity expansion, Abis interface increase and frequency planning are not needed, and the network congestion caused by burst traffic can be effectively solved. However, half rate also has some negative effects, such as: therefore, when channel allocation is performed, the principle of increasing the utilization ratio of HR in busy time, reducing the use of FR, reducing the use of HR in idle time, and ensuring the requirement of preferential use of FR is generally followed. However, in the allocation method of the wireless channel in the prior art, an operator generally uses a half rate to relieve communication pressure under the condition of short channel resources, and in order to increase the HR ratio of the half rate in busy hours, the HR start threshold is often set to be very low, so that no congestion can be guaranteed in busy hours, but the too low HR start threshold makes the half rate not be started in idle hours, and the requirement of reducing the use of the HR in idle hours cannot be met, which requires preferential use of FR. Therefore, the allocation method of the wireless channel in the prior art cannot flexibly adjust the allocation of the wireless channel according to actual requirements.

Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The embodiment of the invention provides a wireless channel configuration method, which is characterized in that a server is additionally arranged in the hardware architecture of the existing communication system and mainly finishes two aspects of work: and synchronizing the traffic statistic data in the network management server in real time (such as synchronizing every 15 minutes). And performing Data analysis on the taken telephone Traffic statistics according to a built-in adaptive configuration algorithm, generating a real-time half-rate Channel and Packet Data Traffic Channel (PDTCH) configuration scheme, synchronously generating an execution script, importing the execution script into a network management server, and executing to complete adaptive configuration. Referring to fig. 1, the method flow includes:

s101, acquiring traffic statistic data of a cell in a previous time period in real time;

s102, analyzing the use condition of cell channel resources in the last time period according to the traffic statistic data;

s103, dynamically allocating the numbers of the packet service data channels PDTCH and the half-rate channels to the channel resources according to the use condition of the channel resources and a preset algorithm.

In an optional scheme, the traffic statistic data includes traffic volume of the cell in the previous time period, traffic volume of a timeslot Multi-user Voice service (Voice Services over adaptive Multi-user channels on slot, Vamos) paired busy hour, a number of broadcast control channels BCCH, a number of independent dedicated control channels SDCCH, a number of current channels of the cell, and a packet data service channel PDTCH multiplexing degree;

step S102, analyzing the service condition of the cell channel resource in the last time period according to the traffic statistic data, including:

calculating half-rate channel gap x, wherein x is the required traffic channel quantity-available channel quantity;

In practical application, the number of the PDTCH reuse degree can be determined empirically:

the low gear is determined when the PDTCH reuse degree is less than 1.5, the medium gear is determined when the PDTCH reuse degree is between 1.5 and 4, and the high gear is determined when the PDTCH reuse degree is more than 4.

In an optional scheme, step S103, dynamically allocating, according to an algorithm preset by the use condition of the channel resource, the number of packet service data channels and half-rate channels to the channel resource, includes:

and distributing the number of the PDTCH and the half-rate channel according to the value of the half-rate channel gap x, the number of the PDTCH reusability and the preset algorithm.

In practical application, a balance can be found between improvement of Channel congestion and occupation of CS and PS channels, and considering CS priority and Traffic Channel (TCH) priority, the preset formula can be set according to the following strategy:

1. the traffic channel is occupied preferentially, and the voice service is occupied preferentially.

2. Since one full-rate channel can only be used by one user and one half-rate channel can be used by two users, the bearing capacity of the half-rate channel can be doubled compared with the full-rate channel. Therefore, when the traffic is busy, the full rate channel is converted into the half rate channel to be used as much as possible (namely, the occupation proportion of the half rate channel is increased) so as to relieve the congestion.

3. In case the channel is sufficient, half rate is not used as much as possible in order to improve the speech quality.

4. In the case that the full rate channel is sufficient, the idle channel allocates the dynamic PDTCH as much as possible, which is beneficial to providing the PS service rate.

5. In the presence of different magnitude PDTCH assignment requests, a balance between half rate channel and PDTCH channel allocations is achieved.

6. Considering the behavior of the system user, if the PS request is not satisfied, the system will retry continuously, so there should be room for PS services, at least one for them, in any case.

Based on the above principle, the preset algorithm adopted in the present embodiment is as follows, and it should be noted that, in different scenes, the corresponding preset algorithms are different.

For convenience of description, the present invention refers to the formula for calculating the half-rate channel gap x as formula one:

x is the number of traffic channels needed-the number of channels available

As can be seen from formula one, when x is less than 0, it means that the number of available channels (TCH) is already greater than the number of TCH required, and then no half-rate Channel is required; when x is 0, indicating that the number of the current TCH full-rate channels just meets the required TCH without congestion; when x > 0, it indicates that the current system traffic is busy.

Therefore, the preset formula is described by dividing the value range of x into three scenes:

scene one: x is less than 0

The number of TCHs available at this time is already greater than the required number of TCHs, and no half-rate channel is required.

Referring to policy 4, when performing dynamic allocation, the full-rate channels remaining after satisfying the CS requirement are all converted into dynamic PDTCH to the maximum, that is:

number of PDTCH required to be allocated: PDTCH _ Dynamic ═ abs (x);

number of half rate channels to be allocated: HR _ convert ═ 0.

Scene two: x is 0

The current TCH full rate channel number just meets the required TCH without congestion (may not be the busiest, nor the idlest). The half rate channel is not needed at this time, only from the CS operation point of view. However, in order to make the allocation of the half-rate channel and the PDTCH reasonable and thus balance the PS channel, the PDTCH allocation needs to consider the following 4 cases:

when the PDCTH reuse degree is 0, that is, no PDTCH assignment request occurs in the previous time period, according to policy 6, at least one PDTCH needs to be allocated, and a TCH is converted to a half rate, that is:

PDTCH_Dynamic＝1；HR_convert＝1。

when the PDCTH multiplexing degree is not 0, the allocation is carried out according to the grade number of the PDCTH multiplexing degree:

if the PDCTH reuse degree is low, a PDTCH is allocated, and a TCH is converted into a half-rate channel. Namely:

PDTCH_Dynamic＝1；

HR_convert＝1。

if the PDCTH reuse degree is a middle grade, the distributed PDTCH quantity is the middle grade proportion coefficient of the PDCTH reuse degree, namely TCH _ aval, namely Mid _ pd, TCH _ aval, and the available TCH quantity corresponding to the proportion of the converted Mid _ pd is a half-rate channel, namely:

PDTCH_Dynamic＝Mid_pd*TCH_aval；

HR_convert＝Mid_pd*TCH_aval。

if the PDCTH reuse degree is High, the number of PDTCHs allocated is High scaling factor TCH _ aval, High _ pd _ aval, and the available TCHs corresponding to the High _ pd scale are converted to half rate:

PDTCH_Dynamic＝High_pd*TCH_aval；

HR_convert＝High_pd*TCH_aval。。

specifically, a PD reuse degree middle-grade proportional coefficient Mid _ PD and a High-grade proportional coefficient High _ PD are defined, and a recommended value Mid _ PD is 1/4; 1/2 for High _ Pd; when the system is implemented, a range can be configured, and the default value is Mid _ Pd-1/4; 1/2.

Scene three: x > 0

The current system traffic is busy and a larger positive value indicates a busy system. At this time, the problem of congestion is solved first, and the half-rate channel is converted as much as possible to meet the traffic requirement. The allocation may be made at this time based on congestion. Firstly, calculating the congestion rate HR _ convert _ threshold as x/TCH _ aval;

if HR _ convert _ threshold > - > 100%, it indicates that the system is extremely congested and the channel resources are not enough, at this time, the available channels are converted into half-rate channels as completely as possible, and PDTCH is not allocated as much as possible. But in conjunction with policy 6, at least one pd is maintained, i.e. only one PDTCH is allocated when allocated, and the remaining available channels are all converted to half-rate channels, i.e.:

PDTCH_Dynamic＝1；

HR _ convert ═ available channel TCH _ aval-1.

If HR _ convert _ threshold is less than 100%, then part of TCH is converted into half rate, and then the half rate channel gap x is the required traffic channel number TCH _ request-available channel number TCH _ aval;

the computation formula of the TCH number rest _ TCH of the remaining channels which do not need to be converted to the half-rate channel is as follows:

rest_TCH＝TCH_aval-x＝TCH_aval*2-TCH_reauest

consider the PDTCH requirement, but since PDTCH is a full rate channel, it takes on the requirement of one traffic. Therefore, each time one PDTCH is used, one more half-rate conversion channel is needed to support the traffic demand required by the original full-rate channel, and therefore, the distribution needs to be carried out according to the PDCTH reuse degree:

if the DTCH reuse degree in the last time period is 0, the PDTCH is not necessarily divided, and all the PDTCH is reserved for CS service. But with reference to policy 6. at least one pdtch is allocated, i.e. one PDCH is allocated, while x +1 half rate channels are converted, i.e.:

PDTCH_Dynamic＝1；

HR_convert＝1+x。

and if the DTCH multiplexing degree in the last time period is not 0, performing allocation according to the grade number of the PDCTH multiplexing degree.

If the reuse degree of the PDTCH is low, a PDTCH dynamic channel is reserved, and a TCH is added to be at half rate, namely:

PDTCH_Dynamic＝1；

HR_convert＝1+x。

if the PDTCH reuse degree is the middle gear, the PDTCH dynamic channel is retained as the middle scale factor (rest _ TCH) ═ Mid _ pd ═ TCH _ aval (2-TCH _ request), and the equal number of TCHs is converted into a half rate, namely:

PDTCH_Dynamic＝Min{Mid_pd*(TCH_aval*2-TCH_ava1)，rest_TCH/2}；

HR_convert＝x+PDTCH_Dynamic；

if the reuse degree of the PDTCH is High-grade, retaining the PDTCH dynamic channel as the High-grade proportionality coefficient, rest _ TCH, busy time PDTCH discount factor as High _ pd, rest _ TCH, y, and converting TCH with the number of High _ pd, rest _ TCH, y into half rate, namely:

PDTCH_Dynamic＝Min{High_pd*rest_TCH*y，rest_TCH/2}；

HR_convert＝x+PDTCH_Dynamic。

in the above calculation formula, y is the busy PD discount factor y. When telephone traffic is busy, the requirements of PDTCH assignment on channels cannot be met at one step, and a default value of 8 is recommended to give a discount, namely 80%; to free up TCH transitions at half rate for CS traffic.

The following describes the present embodiment with reference to specific scenarios, where configuration update is preset to be performed every 15 minutes:

first, 3 cell level parameters need to be set in the server:

a medium scale factor Mid _ pd; this is a PDTCH reuse between 1.5 and 4 at the granularity of the previous 15 minutes of acquisition, considered empirically to be of a medium level, with a default value of 25% recommended; corresponding adjusting proportion coefficient;

a High-order scaling factor High _ pd; the PDTCH with the granularity of 15 minutes before the PDTCH is obtained has the reusability of more than 4, is considered to be a high level according to experience, and is recommended to have a default value of 50%; corresponding adjusting proportion coefficient;

busy PDTCH discount factor y: (in busy traffic, PDTCH assignment channel requirements cannot be met at all, discounts are made, a default of 8 or 80% is recommended to vacate TCH half-rate for CS traffic.)

Secondly, the traffic statistics that the wireless channel configuration server needs to read include:

cell traffic in the first 15 minutes;

the reuse degree of the PDTCH in the cell in the first 15 minutes;

number of Vamos pairings in the first 15 minutes-increasing Ireland number;

cell BCCH number and SDCCH number for the first 15 minutes.

The number of the current available channels of the cell is 50, and the number of the required traffic channels is 80 according to the traffic statistical data in the first 15 minutes by the minimum granularity; then the channel allocation algorithm for the next granularity is as follows:

the method is applicable to a three-scene algorithm, and the calculated congestion rate HR _ convert _ threshold is x/TCH _ aval is 30/50 < 100%, and needs to be distributed according to the number of the PDTCH reusability:

the remaining number of channels rest _ TCH is 50 × 2-80 — 20;

if the PDTCH reuse was in the high range for the first 15 minutes, at most 1/2 of the remaining rest _ TCH needs to be converted to PDTCH, at which time:

PDTCH_Dynamic＝Min(High_pd*rest_TCH*y，rest_TCH/2)＝Min(50％*20*80％，20/2)＝Min(8，10)＝8

that is, it is calculated that the PDTCH to be converted cannot exceed 10, the discount factor y of the busy PDTCH is 80%, and 8 is discounted into 8, that is:

PD _ Dynamic is 8, and HR _ convert is x + PD _ Dynamic is 30+8 is 38.

The end result is 80 CS traffic demands with 38 TCH slew half rates, making up 76 HRs. And 4 TCH are used to satisfy all 80 CS service requirements. Then TCH _ aval total is 50, leaving 50-38-4 ═ 8 for PDTCH use.

If High _ pd x y is calculated to exceed 10 (depending on the server parameter settings), PDTCH _ Dynamic can only take the upper limit of 10 at this time, i.e. PDTCH uses up 10, since it is then necessary to convert 10 more TCHs to HR to balance the corresponding CS traffic demand. The final calculation results in PDTCH _ Dynamic of 10, HR _ convert of x + PDTCH _ Dynamic of 30+10 of 40.

Under the condition that the telephone traffic is very busy, the PS traffic volume is also very large, in order to highlight the PS traffic demand, the discount factor can be set to be 1, no discount is carried out, and the TCH full-rate channel gives way to the PS traffic demand.

In this case, the system implements balanced configuration in every aspect, that is, in the next 15 recent minutes, on one hand, the system can meet the call requirements of 80 users, and on the other hand, the remaining TCH channels can be determined to be all used for supporting the PDTCH or to be re-supported by a discount according to the requirements.

In practical application, when the dynamic SDCCH function is started, and a large number of position updates occur, dynamic conversion is prioritized and distributed from TCH _ aval. After the position updating burst is finished, the channel participating in the dynamic SDCCH conversion is required to be restored to TCH attribute and is changed back to TCH _ aval.

After the Vamos function is turned on, the traffic volume of a region should not increase or decrease significantly due to the turning on of Vamos unless the cell or period of time is heavily congested. Thus, in the case of pairing with Vamos, Vamos pairing and unpairing of FR and HR can be performed on the matching ratio of FR and HR after the algorithm processing without changing the algorithm. The congestion level during busy hours can be further reduced.

It should be noted that, when adding the dynamic SDCCH and/or adding the Vamos, the dynamic SDCCH is mostly a transient change in order to meet the requirement of the burst signaling; while Vamos increases the capacity of the voice channel.

The calculation of TCH _ aval is influenced after the dynamic SDCCH conversion is started, the algorithm is not influenced, and the dynamic SDCCH conversion function completes the stealing and recovery of TCH.

The Vamos function is opened, which is beneficial to improving the system capacity, and the algorithm is used as usual. When activated by Vamos, the busy congestion condition can be alleviated. Using Vamos during idle results in a greater demand for channels by looking up irish tables based on the statistical traffic.

In practical applications, if not so many channels are used, it is necessary to compensate the PDTCH application according to the feedback data of the Vamos pair. The traffic volume that present Vamos goes out excessively, the corresponding TCH quantity that saves, can supply to dynamic PDTCH, when calculating TCH _ aval on the algorithm, according to the situation of the busy hour traffic of former granularity Vamos pairing, deduct.

The wireless channel configuration method of the embodiment can synchronize the traffic statistic data in the network management server in real time. And performing data analysis on the taken telephone traffic statistics according to a built-in self-adaptive configuration algorithm to generate a real-time half-rate and PDTCH configuration scheme. And the synchronous generation command script is led into a network management server to be executed, the self-adaptive configuration is completed, and reasonable distribution between the CS service and the PS can be ensured when the system is busy or idle.
