Description

一种集群系统前向共享信道总功率控制方法 The former method for controlling the total power of a cluster system to a shared channel

技术领域 FIELD

本发明涉及集群通讯技术领域,尤其涉及一种集群系统前向共享信道总功率控制方法。 The present invention relates to a trunking communication technology, and particularly relates to a method of controlling the total power of the shared channel before the cluster system.

背景技术 Background technique

CDMA 2000标准属于3G系统标准体系之一,该标准为用户提供语音和高速分组数据服务。 3G CDMA 2000 system standards are one standard system, to provide users with the standard voice and high-speed packet data services. 集群通讯系统作为一种专用调度通信系统,具有信道资源共享、用户分组、多级优先控制、系统容量大等特点。 Trunking communication system as a dedicated dispatching communication system having a shared channel resource, a user packet, the multi-stage priority control, the system capacity and other characteristics. 由于集群呼叫的广播特性,在CDMA 2000系统上提供集群业务,同一组内一般采用前向业务信道共享的方式,即一个扇区内同一组的所有集群用户共享一个前向业务信道,用于向这些用户广播话音。 Due to the broadcast nature of group call, there is provided a trunking service on the CDMA 2000 system, generally before the shared traffic channel way, i.e., all cluster users in a sector of the same group share the channel a forward channel to the service in the same group, for the these users voice broadcast.

目前前向共享信道的一种方法是"Dedicated mode",即专用模式的信道共享方式。 A method currently shared forward channel is "Dedicated mode", i.e., dedicated channel sharing mode. 该模式下对每个用户有一个CE (信道单元)发射F-TCH (前向业务信道)信号,这些CE的信道参数完全一样,包括WALSH码、长码掩码、帧偏置等,通过CDMA 2000的快速功率控制机制,每个用户各自对其对应的CE进行功率控制,由于用户接收到的信号是所有CE发射功率合成后的信号,因此可以达到功率共享的目的。 In this mode there is for each user a CE (channel element) transmitting F-TCH (Forward Traffic Channel) signal, the CE channel parameter exactly the same, including WALSH code, long code mask, frame offset, etc., through the CDMA fast power control mechanism 2000, for each user a respective power control corresponding to its CE, since the user signal received is a signal to transmit power all CE synthesis, it is possible to achieve power sharing.

CDMA 2000系统对每个F-TCH都配置了一组功率参数:MinGainRatio和MaxGainRatio ,用来控制每个信道的最小/最大发射功率比例;其中MinGainRatio保证用户得到最基本的功率来保证通话质量,MaxGainRatio用来避免过多占用系统资源、增加系统负荷。 CDMA 2000 system, each of the F-TCH are arranged a set of power parameters: MinGainRatio and MaxGainRatio, for the minimum / maximum ratio to control transmission power of each channel; wherein MinGainRatio ensure that users get the basic power to ensure call quality, MaxGainRatio to avoid too many system resources, increase system load. 所述专用模式的信道共享方式下,由于基站是通过多个CE来发射相同的F-TCH,如果仅仅依靠CDMA 2000系统的快速功率控制机制,每个CE的功率可以控制在MinGainRatio和MaxGainRatio之间,但总功率有可能远远超过MaxGainRatio, —方面浪费了系统功率资源,另一方面可能使前向负荷过载 Under the dedicated channel sharing mode, the base station is to transmit the same through a plurality of F-TCH CE, if only relying on fast power control mechanism CDMA 2000 system, the power of each CE can be controlled between MinGainRatio and MaxGainRatio but there is likely to far exceed the total power MaxGainRatio, - aspects of the waste system power resources, on the other hand may make over the load before overload

引起系统崩溃。 Cause a system crash.

所述的专用模式的信道共享方式还存在一个问题:CDMA 2000对每个用户的前向CE都设置了一个参数MaxGainRatio,表示这个信道的最大功率占总功率的比例,用来控制前向最大功率,该参数值由网络运营调整得到。 Sharing said channel dedicated mode is also a problem: CDMA 2000 former for each user are set to a CE parameter MaxGainRatio, this represents the largest proportion of the total power of the channel power, the maximum power used to control the front the parameter values ​​obtained by the network operator adjustment. 当只有一个集群用户时,这种共享信道就表现为一个普通用户,因此, MaxGainRatio信道参数应该与CDMA 2000普通用户设置的相同,才能既保证其通话质量,又不会浪费功率;当有几个用户无线环境较差时,各用户的CE 的发射功率之和就会变得很大,有可能超过MaxGainRatio甚至超过100。 When only one cluster users, this shared channel would appear as a normal user, and therefore, the same MaxGainRatio channel parameters and CDMA 2000 should be set by a normal user, in order to ensure both its call quality, and will not waste power; when there are several user wireless environment is poor, the transmission power of each user and the CE will become great, there may be more than MaxGainRatio even exceed 100. /。 /. , 造成前向功率浪费甚至过载,降低了系统容量并可能导致系统崩溃。 , Even before causing an overload to power waste, reduces system capacity and may cause the system to crash.

本发明的核心思想是提供一种集群系统前向共享信道总功率控制方法, 通过将系统转入慢控模式来控制前向共享信道的总功率,在保证接收最差的集群用户所需要的前向业务信道功率的同时,避免有几个用户无线环境较差造成前向业务信道功率之和过大的问题,达到降低系统负荷的目的。 The core idea of ​​the present invention is to provide a cluster system before the forward shared channel total power control method, controlled by the control system into the slow mode, the total power of the shared channel, received before the worst cluster user to ensure the desired At the same time the traffic channel power, to avoid the first few user of the wireless environment caused by poor traffic channel power ratio and the problem of excessive, to reduce the system load. 本发明提供一种集群系统前向共享信道总功率控制方法,当群组呼叫建 The present invention provides a cluster system the forward channel to a shared channel total power control method, when a group call setup

立后,默认进入快控模式,即同一共享信道上的各CE都发射功率,各CE的发射功率根据对应的MS (移动台)上报的功控信息在系统配置的最小功率比例值SYS一MIN一GAIN一RATIO和最大功率值比例值SYS—MAX—GAHSLRATIO之间进行调整,功控频率一般为800Hz、 600Hz、 400Hz或200Hz,此期间BTS (基站收发信台)周期性查询该群组各CE的发射功率,计算总功率,当总功率超过预先设定上限值时,进入慢控模式。 After standing, to enter fast mode control, i.e. the same channels are shared among the CE transmit power, minimum transmit power of each power ratio reported by the CE corresponding to the MS (mobile station) power control information is arranged in a system SYS value MIN a GAIN rATIO a maximum power value and the scale value is adjusted between SYS-MAX-GAHSLRATIO, power control frequency is typically 800Hz, 600Hz, 400Hz or 200Hz, BTS (base transceiver station) periodically query the group during each CE transmit power, to calculate the total power, when the total power exceeds the preset upper limit value, control enters slow mode. 本实施例以该方法应用于CDMA系统为例进行说明,其操作流程如图1所示, 具体包括如下步骤: In this embodiment, the method is applied to the CDMA system as an example, the operation procedure shown in Figure 1, includes the following steps:

步骤l:群组呼叫建立后,默认进入快控模式,BSC (基站控制器)不断发送业务帧Abis-IS-2000 TCH Fwd给BTS, BTS将所述业务帧发送给各MS; Step l: After the group call is established, to enter fast mode control, the BSC (base station controller) continues to send traffic frame Abis-IS-2000 TCH Fwd to the BTS, BTS sends the service frame to each MS;

各CE都发送业务帧Abis-IS-2000 TCH Fwd中携带的空口业务帧,各CE 的功率由各MS的功控信息确定,MS接收到功率合成后的单一TCH (业务信道)信号;在正常的快控模式下,各CE的发射功率根据对应的MS上报的功控信息在系统配置的最小功率比例值SYS—MIN—GAIN一RATIO和最大功率值比例值SYS—MAX一GAIN—RATIO之间进行调整,功控频率一般为800Hz、 600Hz、 400Hz或200Hz; Each CE sends traffic frame Abis-IS-2000 air interface traffic frames carried Fwd the TCH, each CE power by the MS is power control information determination, MS received a single the TCH (traffic channel) signal power combiner; normal under fast control mode, the minimum power ratio of the transmission power of each CE reported by the MS power control information corresponding to system configuration values ​​SYS-MIN-GAIN rATIO a maximum power value and the ratio value between a SYS-MAX GAIN-rATIO adjustment, power control frequency is typically 800Hz, 600Hz, 400Hz or 200Hz;

所述SYS—MN—GAIN—RATIO是系统配置的最小功率比例值,通常采用典型值,或者通过网络运营进行调整,是一个相对稳定的值,普通业务和集群业务都使用这个配置的值,该值限定了一个信道的最小发射功率占总功率的比例; The SYS-MN-GAIN-RATIO is the ratio of the minimum value of the power system configuration, typical values ​​commonly used, or adjusted by the network operator, is a relatively stable value, ordinary service operations and use this value the cluster configuration, the value defining a minimum channel transmit power ratio of the total power;

所述SYS—MAX—GAIN—RATIO是系统配置的最大功率比例值,通常采用典型值,或者通过两络运营进行调整,是一个相对稳定的值,普通业务和集群业务浙使用这个配置的值,该值限定了一个信道的最大发射功率占总功 The SYS-MAX-GAIN-RATIO is the ratio of the maximum value of the power system configuration, typical values ​​commonly used, or adjusted by two network operators, is a relatively stable value, and clustering operations Zhejiang ordinary traffic usage value of this configuration, this value defines a channel maximum transmission power of the total power

8率的比例; Rate Comparative Example 8;

步骤2: BTS周期性查询该群组各CE的发射功率,并计算总功率; 不论是在快控模式下还是在慢控模式下,BTS都要周期性计算各CE的 Step 2: BTS periodically queries the transmit power of each CE group, and calculates the total power; either slow or in the control mode, the BTS must be periodically calculated for each CE in the mode of fast control

发射功率,并计算总功率,该查询周期可4艮据需要设定; Transmit power, and calculates the total power, the polling period may be set as needed Gen 4;

步骤3:判断所述总功率是否超过预先设定上门限值,若未超过上门限 Step 3: determining the total power exceeds the preset upper threshold, the upper threshold if not exceeded

值,则结束操作; Value, the operation is ended;

为判断总功率而预先i殳定的上门限值比系统配置的最大功率比例值SYS一MAX一GAIN—RATIO高; The maximum power ratio of the total power is determined in advance i Shu predetermined upper threshold value higher than the system configuration a SYS a MAX GAIN-RATIO;

步骤4:若所述总功率超过预先设定上门限值,则选择一个CE,记作CEp,令功控模式为慢控模式,即令FpcMode-FFPC—DISABLED;令功率比例为系统配置的最大比例值,即令GainRatio-SYS一MAX—GAIN—RATIO; Step 4: If the total power exceeds the preset upper threshold, selecting a CE, referred to as CEP, so that the slow power control mode is the control mode, and even if FpcMode-FFPC-DISABLED; power ratio so that the largest proportion of the system configuration value, and even if GainRatio-SYS a MAX-GAIN-RATIO;

同时BTS将该共享信道对应的所有CE的功控模式都设为慢控模式,即令FpcMod^FFPC一DISABLED;除CEp外,将其他CE的功率比例值设置为0; The BTS simultaneously all shared power control channel corresponding to the CE mode are set to the slow mode control, and even if a FpcMod ^ FFPC DISABLED; CEP addition, the additional power ratio CE value is set to 0;

通过此方式可以使慢控模式下只有一个CEp有输出功率,其他CE的输出功率为0,因此可以控制共享信道的总功率; This embodiment can control the slow mode has only one CEp output power, the output power of the other CE is 0, it is possible to control the total power of the shared channel;

步骤5:启动定时器T—FAST—MODE及定时器T—MAX—GAIN—RATIO; Step 5: starting a timer T-FAST-MODE and the timer T-MAX-GAIN-RATIO;

为避免系统在两种状态间频繁切换,在系统进入慢控模式时,开启定时器T一FAST一MODE,使在定时器未超时前不允许切换回快控模式; In order to avoid frequent switching of the system between two states, when the system enters the slow mode control, a timer T is turned on a FAST the MODE, the switching back to the fast control mode is not allowed before the timer does not expire;

由于BSC的慢速功控有秒级的滞后,因此在刚进入慢控模式后,为避免上述所选的CEp用户的功率不能满足用户的需要,BTS需要在进入慢控模式后启动一个定时器T一MAX一GAIN一RATIO,在该定时器超时前将CEp的功率锁定为SYS—MAX—GAIN—RATIO,超时后由BSC下发的业务帧Abis-IS-2000 TCHFwd中承栽的功率比例来调整CEp的功率,而BSC下发的功率值则由MS的功率测量消息来调整,该功控频率为秒级,从此系统进入慢控模式。 Since the slow power control BSC lag of several seconds, and therefore immediately after the control enters the slow mode, to avoid the CEp user selected power can not meet the needs of users, the BTS needs to start a timer after entering the slow mode control a T-MAX GAIN a rATIO, the timer times out before the power CEp locked SYS-MAX-GAIN-rATIO, after a timeout to the power ratio of the traffic frames sent Abis-iS-2000 TCHFwd planted in the bearing BSC CEp adjust the power, and the power values ​​delivered by the BSC by the MS to adjust the power measurement message, the power control frequency of the second level, since the system enters the slow mode control.

9系统进入慢控模式后,进行业务帧发送、模式控制、共享信道功率调 9 after the control system enters the slow mode, the traffic frame transmission, the control mode, the shared channel power adjustment

步骤13 : 若没有超时,则仍令CEp的功率比例值为SYS—MAX—G層一RATIO; Step 13: If not timed out, so that the power ratio remains CEp value SYS-MAX-G RATIO of a layer;

步骤14: BTS将所述业务帧发送给MS,此过程中仍只有CEp发射功率, 其他CE发射功率为O。 Step 14: BTS frame to the service the MS, the process is still only CEp transmit power, transmit power of the other CE is O.

慢控模式下的模式控制过程如图3所示,具体包括如下步骤: Slow mode control process in the control model shown in Figure 3, includes the following steps:

步骤20: BTS判断定时器T—FAST—MODE是否超时,若未超时,则结束操作; Step 20: BTS determines whether the timer times out T-FAST-MODE, if not timed out, the operation is ended;

步骤21: 若超时,则判断当前CEp是否小于预先设定的下门限值T一MIN,若CEp不小于所述下门限值T一MIN,则结束操作; Step 21: If a timeout, it is determined whether the current CEp less than the preset lower threshold T a MIN, if CEp not smaller than the lower threshold T a MIN, the operation is ended;

步骤22:若确定CEp小于所述下门限值T一MIN,则令该共享信道上的所有CE的功控模式为快控模式,即令FpcMode-FFPC—ENABLED,系统进入快控纟莫式; Step 22: if it is determined CEp is less than the lower threshold T a MIN, then enabling the shared power control channel is a fast mode of all CE control mode, and even if FpcMode-FFPC-ENABLED, the system enters the speed control formula Si Mo;

慢控模式下,共享信道的功率调整操作如图4所示,具体包括如下步 The slow mode control shared channel power adjustment operation shown in FIG. 4, it includes the following steps

步骤30: MS采用门限上报的方式上报功率测量信息PMRM; 各MS测量接iJi:到的CE的业务帧,当FER (误帧率)超过指定的值时, 向BTS上报功率测量信息,BTS将所述信息传送给B SC;步骤31: BSC周期性根据所述上报的FER调整功率比例GainRatio; Step 30: MS using the threshold reporting manner reporting power measurement information PMRM; each MS measures the contact iJi: to CE traffic frames, when the FER (Frame Error Rate) exceeds a predetermined value, reporting power measurement information to a BTS, BTS will the information is transmitted to the B SC; step 31: BSC periodically adjusted according to the power ratio GainRatio reported by the FER;

BSC调整GainRatio的原则为:如果所有MS都不上报PMRM,则下降功率比例;如果有上报,则根据上报的FER上调功率比例,该周期可根据需要设定。 BSC is adjusted GainRatio principle: if not all MS PMRM report, decreased power ratio; if there are reported, according to the FER regulated power ratio reported, this cycle can be set as required.

慢控模式下,若发生所选的CE掉话、退出或切换,则需删除所述CE, 另选一CE记作CEx,该过程如图5所示,具体包括如下操作: The slow control mode, if the selected CE dropped calls, handover, or exit, the need to remove CE, alternatively referred to as a CE CEx, the process shown in Figure 5, comprises the following operations occur:

步骤41:令所选的CEx的功率比例值等于原CEp的功率比例值,将CEx 作为新的CEp; Step 41: CEx so selected power ratio is equal to the original value of the power ratio of the CEP, the CEP as the new CEx;

步骤42:删除原CEp; Step 42: Remove the original CEp;

综上所述,本发明通过慢控模式控制前向共享信道的总功率,在保证接收最差的集群用户所需要的前向业务信道功率的同时,避免有几个用户无线环境较差造成前向业务信道功率之和过大的问题,达到降低系统负荷的目的。 In summary, the present invention before a slow controlled by the total power control mode to the shared channel, received before the worst cluster user to ensure the required traffic channel power at the same time to avoid the user has several wireless environment caused by poor before to channel and traffic channel powers of the problem of excessive, to reduce the system load.
