If channel 0 on the main BCCH TRX is set to Combined BCCH or BCCH+CBCH, this parameter can be set to 1 Compounding CCCH.If channel 0 on the main BCCH TRX is set to Main BCCH, this parameter can be set to N Non-compounding CCCH, where N indicates the sum of channels 0, 2, 4, and 6 that are configured as main BCCHs and BCHs.

Number of multiframes in a cycle on a paging sub-channel. In fact, this parameter specifies the number of paging sub-channels that a paging channel in a cell is divided into.In an actual network, an MS does not listen to other paging sub-channels but its belonging paging sub-channel only. Refer to GSM Rec. 05.02 and GSM Rec. 05.08. The larger the value of this parameter, the more the number of the paging sub-channels in a cell, and the fewer the number of the users belonging to each paging sub-channel. In this case, the mean uptime of the MS battery can be prolonged. Refer to the computing mode of paging group in GSM 05.02 of GSM Standards. The larger the value of this parameter, however, the larger the time delay of a paging message in a space segment. Thus, the average service performance of the system lowers. Based on the principle of ensuring that overload does not occur to paging channels, you must set this parameter to a value as small as possible. You must regularly measure the overload conditions of the paging channels in a running network and accordingly adjust the value of this parameter properly. A paging message in a location area must be sent in all the cells within this location area at the same time. Therefore, the capacity of a paging channel of each cell in a location area must be the same or nearly the same. The capacity refers to the calculated number of paging sub-channels of each cell.

GUI Value Range

Actual Value RangeAfter the MS initiates the immediate assignment procedure, it always listens to the messages on the BCCH and all the common control channels (CCCHs) in the CCCH group to which the MS belongs. If the MS does not receive Immediate Assignment or Immediate Assignment Extend messages, it retransmits Channel Request messages at a specified interval.

If the downlink quality is poor, the MS may send SABM frames to the BTS multiple times.When S increases, the interval between two adjacent channel request messages increases, and RACH conflicts decrease, thus improving the usage of AGCH and SDCCH.The access time of the MS, however, is prolonged and the network performance is decreased when T and S increase. Under normal conditions, an appropriate T value should be used to ensure that S is as low as possible, and ensure that AGCH and SDCCH are not overloaded.

Time for disconnecting a call when the MS fails to decode the SACCH. Once a dedicated channel is assigned to the MS, the counter S is enabled and the initial value is set to this parameter value.Each time an SACCH message is not decoded, the counter S decreases by 1. Each time an SACCH message is correctly decoded, the counter S increases by 2. When the counter S is equal to 0, the downlink radio link is considered as failed. Therefore, when the voice or data quality is degraded to an unacceptable situation and it cannot be improved through power control or channel handover, the connection is to be re-established or released.When the BTS receives the SACCH measurement report from the MS, the counter for determining whether a radio link is faulty is set to the value of this parameter. Each time the BTS fails to decode the SACCH measurement report sent by the MS, the counter decreases by 1. If the BTS successfully decodes the SACCH measurement report, the counter increases by 2.When the value of this parameter is 0, the BTS regards the radio link as faulty. The BTS sends a connection failure indication message to the BSC6900. The number of SACCH multi-frames and the radio link failure counter in the system message specify the radio link failure time on the uplink and that on the downlink respectively. The judgment standard is whether the measurement report in SACCH is correctly decoded.A set of NCCs of the cells to be measured by the MS. This parameter is an information element (IE) in the system information type 2 and 6 messages. If a bit of the value of this parameter is set to 1, the MS reports the corresponding measurement report to the BTS. The value of this parameter has a byte (eight bits). Each bit maps with an NCC (0~7) and the most significant bit corresponds to NCC 7. If bit N is 0, the MS does not measure the cell level of NCC N.

In a GSM900 cell, the maximum power control level of an MS ranges from 0 to 19, corresponding respectively to the following values (unit: dBm): 43, 41, 39, 37, 35, 33, 31, 29, 27, 25, 23, 21, 19, 17, 15, 13, 11, 9, 7, and 5. Generally, the maximum transmit power supported by an MS is level 5 (corresponding to 33 dBm). The minimum transmit power supported by an MS is level 19 (corresponding to 5 dBm). Other transmit power levels are reserved for high-power MSs.In a GSM1800 or GSM1900 cell, the maximum power control level of an MS ranges from 0 to 31, corresponding respectively to the following values (unit: dBm): 30, 28, 26, 24, 22, 20, 18, 16, 14, 12, 10, 8, 6, 4, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 36, 34, and 32.

Proper setting of this parameter can reduce the number of handover times, helpful for assigning an MS to a better cell. In a special case that the PT is 31, the larger the CRO value is, the lower the possibility of handing over an MS to the cell.Generally, do not set the CRO to a value larger than 25 dB. The CRO with a too large value will cause uncertain states in a network. The CRO values of the cells with different priorities in a network are almost the same. Refer to GSM Rec. 05.08 and GSM Rec. 04.08. The setting of this parameter affects only the MSs supporting the protocol of GSM Phase 2 or a later version.

The BTS includes the information of different physical layers in the Physical Information message, thus ensuring correct traffic transmission for the MS. If the timer timeouts before a SAMB frame is received from the MS, the BTS retransmits the Physical Information message to the MS. For details, see protocols 08.58 and 04.08.

Whether an MS uses the calculated value as the final receive level value. The calculated receive level value is the measured receive level value minus the receive level value obtained from the BCCH TRX timeslots. This parameter is a cell option in system messages 3 and 6. It is used to indicate MS whether to delete received level valueobtained from the timeslots of BCCH when MS measures receiving level during base band hopping mode.Whether a cell is an extension cell.A double-timeslot extension cell regards an additional TDMA frame as access delay extension. In theory, the supported TA value is 219, that is, a time delay of about 120 kilometers.

Threshold used for interference measurement.The BSS measures the uplink quality of the radio channels occupied by MSs, and calculates and reports the interference on each of the idle channels. This helps the BSC6900 to assign channels. According to the strength of interference signals, the interference signals are classified into five interference levels. The values of these levels are called interference band thresholds. The BTS determines the current interference level based on these thresholds, and then reports a radio resource indication message to the BSC6900. The BSC6900 compares the busy and idle channels reported in the measurement report and in the radio resource indication message to determine whether to perform a handover. The interference band statistics result provides reference for threshold setting and interference analysis.

Distance between the boundary of the overlaid subcell and the boundary of the underlaid subcell. This parameter specifies the difference between the coverage of the overlaid subcell and the coverage of the underlaid subcell in the concentric cell or dual-frequency network scenario. The boundaries of the overlaid and underlaid subcells are determined according to the relative value between the signal strength of the serving cell and the signal strength of the neighbor cell. Assume that the signal strength of the serving cell is SS(s) and that the signal strength of the neighbor cell is SS(n). If SS(s) = SS(n), the MS is on the boundary of the underlaid subcell. If SS(s) - SS(n) > "Distance Between Boudaries of Subcells", the MS is in the coverage of the overlaid subcell.In the tight BCCH handover algorithm, this parameter specifies the difference between the coverage of the TRX that carries the BCCH and the coverage of the TRX that does not carry the BCCH. The relevant computation is the same as the preceding computation.

According to the P/N rule, if the conditions for the handover between the subcells of an enhanced dual-frequency network are met during P of N measurements, the handover is triggered.This parameter specifies the number P.According to the P/N rule, if the conditions for the handover between the subcells of an enhanced dual-frequency network are met during P of N measurements, the handover is triggered.This parameter specifies the number N.

Actual Value Range

In the handover algorithm of the first generation, load handovers can be performed only when the receive level of the current serving cell is in the range "Edge HO DL RX_LEV Threshold" to "Edge HO DL RX_LEV Threshold" + "Load HO Bandwidth". In the handover algorithm of the second generation, load handovers can be performed only when the level difference between the neighboring cell and the serving cell is between "Inter-cell HO Hysteresis" - "Load HO Bandwidth" and "Inter-cell HO Hysteresis".When the load of a cell reaches or exceeds "Load HO Threshold", all the calls that are using this cell as the serving cell generate handover requests at the same time, which will suddenly increase the load of the processor. Under some circumstances, congestion occurs in the cell, which will result in call drop. To solve this problem, the BSC uses the hierarchical load handover algorithm to control the number of users included in each level of handovers. This parameter indicates the duration of each handover level.

GUI Value Range

Actual Value RangeIf a cell supports the enhanced concentric cell function, when an overlaid-to-underlaid handover or an underlaid-to-overlaid handover is decided, the MS compares the receive level value respectively with the values of "OtoU HO Received Level Threshold" and "UtoO HO Received Level Threshold" in "SET GCELLHOIUO" to decide whether to trigger an enhanced concentric cell handover.

If the cell does not support the enhanced concentric cell function, the MS compares the actual receive level value with the threshold of receive level to decide whether to trigger a concentric cell handover. In addition, when an underlaid-to-overlaid handover is decided, the underlay cell load is considered.

One of the parameters that decide the underlay and overlay areas. If "Enhanced Concentric Allowed" is set to OFF, the underlay and overlay areas are determined by "RX_QUAL Threshold", "RX_LEV Threshold", "RX_LEV Hysteresis", "TA Threshold", and "TA Hysteresis" together; if "Enhanced Concentric Allowed" is set to ON, the underlay and overlay areas are determined by "RX_QUAL Threshold", "UtoO HO Received Level Threshold", "OtoU HO Received Level Threshold", "TA Threshold", and "TA Hysteresis" together.When "Enhanced Concentric Allowed" is set to OFF, "TA Hysteresis", "RX_LEV Threshold", "RX_LEV Hysteresis", "RX_QUAL Threshold", and "TA Threshold" determine the coverage of the OL subcell and UL subcell.When "Enhanced Concentric Allowed" is set to ON, "TA Hysteresis", "UtoO HO Received Level Threshold", "OtoU HO Received Level Threshold", "RX_QUAL Threshold", and "TA Threshold" determine the coverage of the OL subcell and UL subcell.When "Enhanced Concentric Allowed" is set to OFF, "TA Hysteresis", "RX_LEV Threshold", "RX_LEV Hysteresis", "RX_QUAL Threshold", and "TA Threshold" determine the coverage of the OL subcell and UL subcell.When "Enhanced Concentric Allowed" is set to ON, "TA Hysteresis", "UtoO HO Received Level Threshold", "OtoU HO Received Level Threshold", "RX_QUAL Threshold", and "TA Threshold" determine the coverage of the OL subcell and UL subcell.

If the existing call is performed in the UL subcell, a UL subcell to OL subcell handover is triggered, and "UL to OL HO Allowed" is set to YES, the timer is started and the calls in the UL subcell are hierarchically handed over to the OL subcell if the traffic volume in the UL subcell reaches "En Iuo Out Cell General OverLoad Thred". Otherwise, if the traffic volume in the UL subcell is smaller than "En Iuo Out Cell General OverLoad Thred", the timer stops, and hierarchical handovers are not performed.If this parameter is set to NO, the traffic volume in the UL subcell is not taken into account for triggering the UL subcell to OL subcell handover or the OL subcell to UL subcell handover in an enhanced concentric cell.

If all the calls in the overlaid subcell are handed over to the underlaid subcell when the channel seizure ratio of the underlaid subcell is less than "En Iuo Out Cell Low Load Thred", the BSC load increases sharply. In this case, the target subcell may be congested and drop calls. To avoid such a problem, the hierarchical load-based handover algorithm is used to hand over the calls from the overlaid subcell to the underlaid cell level by level.This parameter specifies the period of the handover at each hierarchy level.

Distance between the boundary of the overlaid subcell and the boundary of the underlaid subcell. This parameter specifies the difference between the coverage of the overlaid subcell and the coverage of the underlaid subcell in the concentric cell or dual-frequency network scenario. The boundaries of the overlaid and underlaid subcells are determined according to the relative value between the signal strength of the serving cell and the signal strength of the neighbor cell. Assume that the signal strength of the serving cell is SS(s) and that the signal strength of the neighbor cell is SS(n). If SS(s) = SS(n), the MS is on the boundary of the underlaid subcell. If SS(s) - SS(n) > "Distance Between Boudaries of Subcells", the MS is in the coverage of the overlaid subcell.In the tight BCCH handover algorithm, this parameter specifies the difference between the coverage of the TRX that carries the BCCH and the coverage of the TRX that does not carry the BCCH. The relevant computation is the same as the preceding computation.

GUI Value Range

Actual Value RangeWhether power control algorithm II allows measurement report compensation.

When making a power control decision, the BSC retrieves a certain number of history measurement reports and performs weighted filtering on the receive level values and receive quality values in these reports, which may be obtained when different transmit powers were used by BTSs or MSs. To ensure that correct receive level values and receive quality values are used in filtering, you must compensate the receive level values and receive quality values in history measurement reports obtained when transmit powers different than the current one were used.To compensate the delay of power adjustment, the power control algorithm implements the prediction and filtering function. In other words, the BSC samples several uplink measurement reports, performs weighted filtering, and predicts N measurement reports from the current time onwards in a short period. This parameter determines the number of uplink measurement reports predicted by the BSC. In other words, the value of this parameter equals to the previous number N.To prevent late power control to a certain degree, the power control algorithm involves a measurement report prediction filter. The BSC can sample several downlink measurement reports in a short time and then weight them to predict future N measurement reports.This parameter specifies the number N.

Power decrease = downlink received signal level - ("DL RX_LEV Upper Threshold" + "AMR DL RX_LEV Lower Threshold")/2The maximum power adjustment step allowed by the quality zone is chosen from "MAX Down Adj.Value Qual.Zone 0", "MAX Down Adj.Value Qual.Zone 1", and "MAX Down Adj.Value Qual.Zone 2" according to the quality zone.If the downlink received signal level is less than this threshold, a power increase is computed. Then, the power is increased by the least of the power increase, "MAX Up Adj. PC Value by RX_LEV", and "MAX Up Adj. PC Value by Qual.".Power increase = ("DL RX_LEV Upper Threshold" + "AMR DL RX_LEV Lower Threshold")/2 - downlink received signal level

Statistical multiplexing means that signaling timeslots are time-division multiplexed in an E1 timeslot, such as the OML and RSL timeslots or the RSL timeslots. For example, in the case of 4:1 multiplexing, one 64 kbit/s timeslot multiplexes one OML and three RSL links or four RSL links of the BTS. The 64 kbit/s timeslot that multiplexes the OML has a multiplexing ratio of up to 4:1 even if the multiplexing ratio exceeds 4:1.HDLC and IP BTS is not support this parameter.

In the case of half-rate networking, each E1 supports up to 13 TRXs. If the LAPD signaling links are unmultiplexed, each E1 supports fewer TRXs.

The BSC assigns channels in the overlaid subcell to the MS in a concentric cell. If the channel seizure ratio of overlaid subcell is greater than the value of this parameter, half-rate channels are assigned. Otherwise, full-rate channels are assigned. Channel seizure ratio = (Num. of busy TCHF + Num. of busy TCHH/2)/(Num. of available TCHF + Num. of available TCHH /2) x 100%. This parameter is valid for the concentric cell. When the "Allow Rate Selection Based on Overlaid/Underlaid Subcell Load" is set to Yes, the "TCH Traffic Busy Threshold (%)" is invalid for the concentric cell.

Frequency hopping mode of the TRX. Frequency hopping assists in interference averaging and frequency diversity.If this parameter is set to RF_FH, the TX and RX parts of the TRX take part in the frequency hopping. In this case, the number of hopping frequencies can exceed the number of TRXs in the cell. If this parameter is set to BaseBand_FH, each transmitter works at a fixed frequency. That is, the TX part does not take part in the frequency hopping. The baseband signals are switched for the frequency-hopping transmission. The RX part, however, takes part in the frequency hopping.Hopping sequence number (HSN), indicating 64 types of frequency hopping sequences. If this parameter is set to 0, the frequency hopping is performed in sequence.If this parameter is set to a value from 1 to 63, the frequency hopping is performed in a pseudo-random manner, that is a disciplinary random manner.

The TSC is short for the Training Sequence Code.The TSC must be the same as the BCC. The delay equalization is performed by using the specified TSC when the MS or BTS receives the signal. The demodulation cannot be received because the delay equalization cannot be performed for the signals with same frequency using different TSCs. This can effectively prevent incorrectly invalid reception, and prevent the co-channel interference.
