A configuration command that modifies the basic attributes of a 2G internal cell. In this command, the following parameters uniquely identify the cell:
Cell Index or Cell Name
1. A cell can support GRPS function only when the BSC that controlling this cell is configured with the PCU.
2. If a cell supports EDGE, NC2, NACC, PACKET SI, or PCU64 neighbor cell, it must support the GPRS.
3. If the cell is set to not support the GPRS, the BSC automatically set the cell to not support EDGE, NC2, NACC, PACKET SI or PCU64 neighbor cell.
ID | Name | Description |
---|---|---|
IDXTYPE | Index Type | Meaning:Index Type Value range:BYNAME(By Name),BYIDX(By Index) Explanation: Index Type. Default value:None |
CELLIDX | Cell Index | Meaning:Cell Index Value range:0~2047 Explanation: This parameter indicates the cell number, which is unique in one BSC. Default value:None |
CELLNAME | Cell Name | Meaning:Cell Name Value range:1-32 characters Explanation: This parameter indicates the name of a cell. The value ranges from 1 to 32 characters.The name of each cell under one BSC must be unique. Default value:None |

LAYER | cell layer | Meaning:cell layer Value range:1,2,3,4 Explanation: This parameter indicates the layer where a cell is located. The network designed by Huawei has four layers: Umbrella, Macro, Micro, and Pico. Each layer has 16 priorities. The Umbrella layer refers to the GSM900 layer with a large coverage area. It implements the high-layer coverage and the connection of MSs moving at a high speed. The Macro layer carries most traffic on the GSM900 band. The Micro layer carries most traffic on the DCS1800 band. It solves the problem of insufficient resources. The Micro layer is a main cell layer for dual-band MSs in the future. The Pico layer is a microcell layer on the GSM900 and DCS1800 bands. It meets the requirements for the provisioning of traffic at hot spots and dead zones. Default value:None |
PRIOR | Cell Priority | Meaning:Cell Priority Value range:PRIOR-1(Prior-1),PRIOR-2(Prior-2),PRIOR-3(Prior-3),PRIOR-4(Prior-4),PRIOR-5(Prior-5),PRIOR-6(Prior-6),PRIOR-7(Prior-7),PRIOR-8(Prior-8),PRIOR-9(Prior-9),PRIOR-10(Prior-10),PRIOR-11(Prior-11),PRIOR-12(Prior-12),PRIOR-13(Prior-13),PRIOR-14(Prior-14),PRIOR-15(Prior-15),PRIOR-16(Prior-16) Explanation: This parameter controls handover between cells at the same layer. Generally, the cells at the same layer have the same priority. If the cells at the same layer have different priorities, the cell with a smaller value has a higher priority. Default value:None |
MAXTA | Max TA | Meaning:Max TA Value range:0~255 Explanation: This parameter specifies the actual coverage area of a cell. After receiving the channel request message or handover access message, the BTS determines whether the channel assignment or handover is performed in the cell by comparing the TA and the value of this parameter.

The value of this parameter has eight bits. The eights bits (from the least significant bit to the most significant bit) specify whether to support the A5/0, A5/1, A5/2, A5/3, A5/4, A5/5, A5/6, and A5/7 encryption algorithms respectively. If a bit is set to 1, you can infer that the BSS supports the corresponding encryption algorithm. If a bit is 0, you can infer that the BSS does not support the corresponding encryption algorithm. The eights bits cannot be all zeros and the least significant bit must be 1. Default value:None |
RXMIN | RXLEV_ACCESS_MIN | Meaning:RXLEV_ACCESS_MIN Value range:0~63 Explanation: This parameter specifies the minimum receive level of an MS to access the BSS. For details. see GSM Rec. 05.08. The value of this parameter ranges from 0 to 63 (corresponding to -110 dBm to -47 dBm). Default value:None |
FRULDTX | TCH/F Uplink DTX | Meaning:TCH/F Uplink DTX Value range:May_Use(May Use),Shall_Use(Shall Use),Shall_NOT_Use(Shall not Use) Explanation: This parameter specifies whether to allow the MS to use the Discontinuous Transmission (DTX) function. For details, see GSM Rec. 05.08. Default value:None |
HRULDTX | TCH/H Uplink DTX | Meaning:TCH/H Uplink DTX Value range:May_Use(May Use),Shall_Use(Shall Use),Shall_NOT_Use(Shall not Use) Explanation:This parameter specifies whether to allow the MS that seizes a half-rate TCH to use the uplink Discontinuous Transmission (DTX) function. For details, see GSM Rec. 05.08. The DTX function is implemented on the basis of the following basic functions: voice activity detection (VAD), silence descriptor (SID), and comfort noise. The BSC6000 controls whether to enable the downlink DTX function. For details, see the description of the HR Use Downlink DTX parameter. Default value:None |
CALLRESTABDIS | Call Reestablishment Forbidden | Meaning:Call Reestablishment Forbidden Value range:NO(NO),YES(YES) Explanation: This parameter specifies whether to allow call reestablishment. Blind spots caused by tall buildings or burst interference may lead to failure in radio links. Thus a call may drop. In this case, the MS can initiate a call reestablishment procedure to resume the call. The number of call drops is not incremented if the call reestablishment is successful or if the subscriber hooks on. Default value:None |
IMMASSEN | TCH Immediate Assignment | Meaning:TCH Immediate Assignment Value range:NO(NO),YES(YES) Explanation: If this parameter is set to Yes, the BSC can assign a TCH and an SDCCH when receiving an initial access request. If this parameter is set to No, the BSC can assign only an SDCCH when receiving an initial access request. Default value:None |
DIRECTRYEN | Directed Retry | Meaning:Directed Retry Value range:NO(NO),YES(YES) Explanation: This parameter specifies whether to allow directed retry. In directed retry, a handover procedure is performed to hand over the MS to a neighbor cell. Directed retry is an emergency measure for abnormal peak traffic in the local wireless network. It is not a primary method of clearing traffic congestion. If directed retry is preformed frequently in a local network, you must adjust the TRX configuration of the BTS and the network layout. Default value:None |
UPPCEN | UL PC Allowed | Meaning:UL PC Allowed Value range:NO(NO),YES(YES) Explanation: This parameter specifies whether the adjustment of the MS power is allowed. Default value:None |
DNPCEN | DL PC Allowed | Meaning:DL PC Allowed Value range:NO(NO),YES(YES) Explanation: This parameter specifies whether the adjustment of the BTS power is allowed.. Default value:None |
SDDYN | SDCCH Dynamic Allocation Allowed | Meaning:SDCCH Dynamic Allocation Allowed Value range:NO(NO),YES(YES) Explanation: This parameter specifies whether the SDCCH dynamic allocation is allowed. When the number of GSM subscribers in a cell increases rapidly, many subscribers may fail to access the network due to insufficient SDCCH resources. In this case, the TCHs (including TCH and dynamic PDCH that acts as TCH) must be converted into SDCCHs to ensure the access of most subscribers. The SDCCH dynamic adjustment can increase the system capacity. Default value:None |
LEVELRPT | Level Report Switch | Meaning:Level Report Switch Value range:NO(Not Support), YES(Support), NONE(Invalid) Explanation: For the BTS30, BTS312, BTS3012A, BTS3006A, BTS3012E, and BTS3002E, this parameter is set to "YES (Support)" by default and the default value can be manually modified. For the BTS of other models, this parameter is set to "NONE (Invalid)" and the default value cannot be manually modified, that is, the receive levels of main and diversity are not reported. This parameter specifies whether the BTS sends the measurement report containing the main and diversity level to the BSC. After the BTS reports the main and diversity level to the BSC, the information is mainly used to record traffic statistics. Default value: None |
DYNOPENTRXPOWER | Allow Dynamic Shutdown of TRX Power Amplifier | Meaning:Allow Dynamic Shutdown of TRX Power Amplifier Value range:NO(NO),YES(YES) Explanation: This parameter specifies whether the BSC determines to enable or disable the power amplifier of a TRX based on the traffic volume. Default value:None |
BTSADJUST | Adjust Voltage | Meaning:Adjust Voltage Value range:NO(NO),YES(YES) Explanation: This parameter specifies whether to select different working voltages for the TRX power amplifier in a cell based on different TRX modulation modes. Default value:None |
GMSKDELAY | Diversity Transmitter GMSK Delay | Meaning:Diversity Transmitter GMSK Delay Value range:4~32 Explanation: Generally, the time delay of the transmit diversity is set to 2 bit (7.4 us) and is applied to common attenuation environment. The transmit diversity can achieve a power gain of 3-5 dB. As the attenuation environment differs, a permanent time delay results in different gains for different users. A permanent time delay also has negative impact to the codes of EDGE services. Therefore, the time delay of the transmit diversity should be configurable, and the time delay for the GMSK and the 8PSK should be specified separately. The unit of the time delay parameter is 1/8 bit. The default time delay for GMSK is 2 bit and the default time delay for 8PSK is 1 bit. Default value:None |
8PSKDELAY | Diversity Transmitter 8PSK Delay | Meaning:Diversity Transmitter 8PSK Delay Value range:4~32 Explanation: Generally, the time delay of the transmit diversity is set to 2 bit (7.4 us) and is applied to common attenuation environment. The transmit diversity can achieve a power gain of 3-5 dB. As the attenuation environment differs, a permanent time delay results in different gains for different users. A permanent time delay also has negative impact to the codes of EDGE services. Therefore, the time delay of the transmit diversity should be configurable, and the time delay for the GMSK and the 8PSK should be specified separately. The unit of the time delay parameter is 1/8 bit. The default time delay for GMSK is 2 bit and the default time delay for 8PSK is 1 bit. Default value:None |
ICBALLOW | ICB Allowed | Meaning:ICB Allowed Value range:NO(NO),YES(YES),NULL(NULL) Explanation:This parameter specifies whether to enable the power-saving TRXs. If this parameter is set to Yes, the power-saving TRXs are preferentially enabled. Default value:None |
TIMESLOTVOLADJALLOW | Voltage Adjust Based Timeslots Allowed | Meaning:Voltage Adjust Based Timeslots Allowed Value range:NO(NO),YES(YES),NULL(NULL) Explanation:This parameter specifies whether to enable the dynamic voltage adjustment function based on the number of timeslots. Default value:None |
