在数据上传过程中 BS CV MAX参数控制着上行数据块传输确认的等待时间 即当MS收到BTS发 过来的Packet Uplink ACK NACK消息时 如果某块的标识为 未证实 并且该块最后一次发送的时间和MS收到ACK NACK的时间间隔 小于max BS CV MAX 1 1 这也就是说这个RLC块最近刚被传输 重传 所以认为ACK NACK中的 未证实 是无效的 PCU可以通过BS CV MAX参数的设置来调节资源分配 BS CV MAX的值设置越高 滑动窗口程序的效率越低 数据速率可能变慢 另一 方面 该值越低 MS可能会在证实消息返回之前 又一次重传该RLC数据块 导致无线资源被无效占用的概率增高 目前现网中 BS CV MAX参数设置值主要有6和9这两种 设置9 ping时长短些 在packet idle模式下可以采用DRX或Non DRX方式传送立即指配命令 这也将不同的时延 这个过程由DRX TIMER MAX和手机侧的Non DRX Timer一起共同决定 DRX TIMER MAX 是针对 E GPRS 功能引入的一个参数 它和手机侧的Non DRX Timer一起共同决定了当 E GPRS手机从数据传输模式 状态转移到数据空闲状态时 对CCCH 信道上信令的监听方式 DRX 模情况下 为了省电 手机只是在属于自己的寻呼信道到来时 才会去监听CCCH 信道上的消息从而决定下一步动作 而当网络侧修改DRX TIMER MAX 为一个不为了零的值 手机将会在从数据传输 模式进入到数据空闲模式后立刻进入Non DRX模式 这样在一段特定时间内连续监听CCCH 信道 经过这段时间 手机又进入到DRX 模 式 手机进入Non DRX模式的时间由min DRX TIMER MAX Non DRX Timer 决定 所以当手机本身Non DRX Timer 0时 PDP激活时 延将无法通过参数DRX TIMER MAX修改来得到改善 DTM provides simultaneous CS voice and PS data services MS is simultaneously in dedicated mode and in packet transfer mode Enables the use of data services such as file transfer web browsing video sharing and mobile netmeeting during a speech call EDAP配置注意事项 EDAP是基于BCF进行设定的 单个EDAP不能被多个BCF共享 理论上 一个EDAP 所带的载频数最大为20 但由于EDAP的时隙资源必须与TRX的Master TSL处于同一条传输内 实际最大的附带 的载频数量小于20 EDAP的容量大小为12 64kbps 即48个EDAP子信道 BSC的EDAP容量为470个 With Extended Uplink TBF Mode the uplink TBF may be maintained during temporary inactive periods where the mobile station has no data to send Without Extended Uplink TBF Mode a new uplink TBF has to be established after every inactive period When both the MS and the network support Extended Uplink TBF Mode the release of the uplink TBF can be delayed even if the MS occasionally has nothing to transmit Right after the MS has new data to send the same uplink TBF can be used and data transmission can be reactivated With Extended UL TBF Mode the UL TBF release can be delayed in order to make it possible to establish the following downlink TBF using Packet Associated Control Channel PACCH Using PACCH enables faster TBF establishment compared to using CCCH With this parameter you define the minimum interval between the changes in the radio frequency power level With this parameter you define the optimum downlink RF signal level The optimum level ensures that both speech and data quality are sufficient simultaneously and that there is no downlink interference With this parameter you identify the maximum transmission power of the BTS as an attenuation from the peak power of the TRX This parameter is used for frequency bands GSM 800 and GSM 900 The total attenuation for GSM 800 and GSM 900 band TRXs is

whether the BCCH TRX or other TRXs are preferred in GPRS channel allocation NOTE MML Range 0 no prioritisation is determined between TRXs 1 GPRS channels are allocated primarily from the BCCH TRX 2 GPRS channels are allocated primarily beyond the BCCH TRX With this parameter you define how the MS uses DTX discontinuous transmission 0 移动台可以使用DTX 1 移动台必须使用DTX 2 移动台不允许使用DTX With this parameter you define the percentage of full rate TCH resources that must be available for traffic channel allocation Full rate TCHs are allocated until the number of free full rate resources is reduced below the threshold given in the parameter The half rate resources are then allocated 该参数取值过大 可能导致小区长时间分配半速率信道 导致通话 质量比较差 该参数取值过小 可能导致小区无法分配半速率信道 影响TCH信道接通 With this parameter you define the percentage of full rate TCH resources that must be available for traffic channel allocation Full rate TCHs are again allocated when the number of the free full rate resources increases above the threshold given by the

number dl max number ul With this parameter you define whether the adjacent cell is synchronised with the cell in use When defining adjacencies between the sectors of PrimeSite the value of parameter synchronised must be N not synchronised This is because the sectors of PrimeSite are not synchronised with each other in a fault case when the system has set the sectors to minimum configuration With this parameter you define whether the BCCH TRX or other TRXs of the regular frequency area are preferred in traffic channel allocation Values 0 No prioritisation between TRXs all TRXs are treated equally in TCH allocation 1 Traffic channel is allocated primarily from the BCCH TRX 2 Traffic channel is allocated primarily from another TRX than the BCCH TRX 3 Traffic channel is allocated primarily from the BCCH TRX for the non AMR users and for the AMR users primarily beyond the BCCH TRX With this parameter you can adjust the MCS and modulation preferences This is the offset added to reported 8PSK mean BEP values before BEP table lookups The value applies to both uplink and downlink directions The parameter is used in EGPRS link adaptation 不同小区的GPRS参数MBP优化 MBP是BTS参数 链路自适应运算进行前

modify the Link Access Protocol on the Dm channel LAPDm t200 values in the BSC to ensure that the message transfer in the air interface is not stopped too early Previously the LAPDm t200 values were defined in the BTS SW configuration file which required a new SW build The values are modifiable for full rate half rate and SDCCH channels The downloaded FACCH t200 is used for both full rate and half rate and the one downloaded SDCCH t200 value is used for both SAPI0 and SAPI3 messages The downloaded FACCH t200 is used for both full rate and half rate downloaded SDCCH t200 value is used for
