CDMA2000 1X/1xEV-DO BSS OPMChapter 1. 1X CallControl

1.1 CDMA 1X Call ProcessingThe BSM provides commands that an operator can use to setup and control a call. This chapter describes how to handle various parameters to control various data and calls that are required for call setup during base station operation. It basically describes call processing procedures which are based on wireless connection rules (Air Interface) and network connection rules (A-Interface) and also provides various causes for call setup failures. Call processing is described separately for the base station and Access Control Router (ACR). For the base station, how to check the status of a base station where call setup is possible, how to allocate traffic resources during call setup, and how to control them are described. For the ACR, communication with an MS and communication with a station are described separately. For communication with an MS, various power control parameters, how to control handoff parameter, and configuration of operation conditions for data call setup are described. For communication with a station, the information about IP link connected to the station is described. SAMSUNG Electronics Co., Ltd. 1-1

Chapter 1. 1X CallControl1.2 Access Channel Control1.2.1 Overview

In the BSM, you can execute CHG-MSACH-PARA to control the parameters related to access channels. An access channel related parameter is broadcasted to all the MSs through an Access Parameter message which transfers a paging message in the system. An MS uses the access channel by referring to the parameter of the message. The parameters related to access channel are as followings:

INITIAL_PWR PWR_STEP NUM_STEP MAX_CAP_SIZE PREAMBLE_SIZE PSIST_0_9 PSIST_10 PSIST_11 PSIST_12 PSIST_13 PSIST_14 PSIST_15 MSG_PSIST REG_PSIST PROBE_PN_RANDOM ACC_TIMEOUT PROBE_BACKOFF BACKOFF MAX_REQ_SEQ MAX_RSP_SEQ AUTH NOM_PWR_EXT

Chapter 1. 1X CallControl1.3 Call Admission Control1.3.1 Overview

Call Admission Control (CAC) measures the load of a base station and restricts outgoing calls, incoming calls, or handoff calls if the load is high. The load level is the ratio (percentage, %) of the current Tx Digital Gain vs. max. value of Tx Digital Gain of each subcell. An operator can use MMC to adjust a related parameter, and can use different threshold for each voice call, data call, newly create call, and handoff call. If too many calls are created at a specific base station at specific moments, the total transmission output of the base station goes out of a specific range. In this case, an RF component (e.g. HPA) responsible for output power might be damaged because of an excessive ouputs and this may cause reduced station output or any malfunction of the base station. Call Admission Control restricts the total transmission output of the base station below a specific level to prevent the problems described above to provide stable and continuous call service.

The parameters for Call Admission Control are as followings:

1.2 Parameters for Call Admission Control

Parameter Description Ovhd_CH_Tx_Gain As the sum of Tx Digital Gain of the overhead channels

for each subcell, this is calculated from the Tx Digital Gain DB index value of each overhead channel which is configured in PLD.

Voice_FDCH_Tx_Gain As the sum of Tx Digital Gain of FCHDCCH, which is allocated to a voice call, for each subcell, this is reported from each channel card periodically.

Packet_FDCH_Tx_Gain As the sum of Tx Digital Gain of FCHDCCH, which is allocated to a data call, for each subcell, this is also reported from each channel card periodically.

Initial_Tx_Gain As the initial Tx Digital Gain of FCH or DCCH for a newly created call, this exists in PLD for each radio configuration.

Allowed_Limit_x Threshold used as criteria for call limit The threshold can be different for voice call and data call. 1-22 SAMSUNG Electronics Co., Ltd.

PART I. CallControl CDMA2000 1X/1xEV-DO BSS OPM/Ed.001.3.2 AlgorithmThe following expression is used to determine FA call admission. The expression depends on a call type.

1.3.2.1 Voice New CallOvhd_CH_Tx_Gain+ Voice_FDCH_Tx_Gain +Packet_FDCH_Tx_Gain + Initial_Tx_Gain +Guard_Tx_Gain_vn < Allowed_Limit_v

1.3.2.2 Voice HO CallOvhd_CH_Tx_Gain+ Voice_FDCH_Tx_Gain +Packet_FDCH_Tx_Gain+ Initial_Tx_Gain + Guard_Tx_Gain_vh < Allowed_Limit_v

1.3.2.3 Packet New CallOvhd_CH_Tx_Gain+ Voice_FDCH_Tx_Gain +Packet_FDCH_Tx_Gain + Initial_Tx_Gain + Guard_Tx_Gain_pn < Allowed_Limit_p

1.3.2.4 Packet HO CallOvhd_CH_Tx_Gain+ Voice_FDCH_Tx_Gain +Packet_FDCH_Tx_Gain+ Initial_Tx_Gain + Guard_Tx_Gain_ph < Allowed_Limit_p

If the above expressions are satisfied, a call to corresponding FA is allowed. If not, the call is limited. In the above expression, _v at the end of a parameter means a voice call, _p means a packet call, _h means a handoff call, and _n means a new call.

Guard_Tx_Gain_xx Margin for output fluctuation which may be caused by MS location change or various wireless environments. Each different value can be configured for various call types. If you apply different Guard_Tx_Gain_xx values to a handoff call and a normal call, it has the same effect that you use different thresholds for each of them. In other words, if an operator configures the Guard_Tx_Gain_xx of a normal call higher than the Guard_Tx_Gain_xx of a handoff call, it has the effect that the difference is reserved for handoff. Guard_Tx_Gain and Allowed_Limit, i.e. actual factors which determine thresholds, exist in PLD for each subcell. Each value can be also changed to percentage (0-100%) in UIM.

When an SRDM is sent to AT, system information should be set in mig_ret_fail, mig_band_class, mig_exp_sid, mig_exp_nid, and mig_num_chan in order to move the AT. A unit is not used because this value is a flag. If this value is set to SKT_OFF, the SRDM sending function will not be performed. If this value is set to SKT_ON, the function will be performed. This value is used only in the system. (Refer to 3GPP2 C.S0005-A v6.0 3.7.3.3.2.23.)

MIG_NUM_CHAN Indicates the number of channel information to be transmitted when an SRDM is sent. The unit is number, and this value is used both of the system and AT. (Refer to 3GPP2 C.S0005-A v6.0 3.7.3.3.2.23.)

MIG_CHAN[11] This is a channel information parameter when an SRDM is sent. A unit is not used, and this value is used both of the system and AT. (Refer to 3GPP2 C.S0005-A v6.0 3.7.3.3.2.23.)

STARVATION_THRESHOLD_PER_LEVELDivides the starvation number by the entered starvation_threshold_per_level value and apply the value to the priority in order to have priority to the starvation number when the RF scheduler allocates SCH Walsh resources. For instance, if the starvation number of SCH for a call is 5 and this value is set to 2, 1-50 SAMSUNG Electronics Co., Ltd.

Chapter 1. 1X CallControl1.4 Overload Control1.4.1 Overload

1.4.1.1 Overload DefinitionIf there are continuous incoming calls more than the system capability and it significantly affects the normal operation of a processor which handles the incoming calls, it is called overload.

1.4.1.2 Reason for Increased LoadThe main reasons for increased load in the BSS system are as followings:

Too many mobile stations (MS) accesses the system Several processors are loaded simultaneously or excessive batch job is executed Several tasks are executing many jobs at the same time

1.4.1.3 Overload SymptomIf call traffic is abruptly increased or a specific processor is failed frequently during system operation, check the status of each processor. You can check hourly report analysis, response time to MMC, OS related error message in a system, memory usage, and the number of IPC messages, etc.

1.4.1.4 Overload Detection and Load status ReportHow to detect overload and the report path of load status are described.

Overload Detection and JudgmentThe CPU load of CMP and BCP processors can be used to judge system overload. In other words, CMP and BCP periodically receive CPU idle time from OS and calculate CPU load ratio. CMP and BCP compare the calculated CPU load ratio value to overload threshold, and judge overload in 4 levels. The 4 levels are NORMAL, MINOR, MAJOR, or CRITICAL. (CPU load is measured by COSHX in the CMP and it is measured by BSHX in the BCP. )))

Load status ReportCMP receives overload status information from the COSHX block which measures the CPU load of OAM when the information of a corresponding CPU overload status is changed. In addition, the MCCX of CMP transfers BSC overload status to a base station every 2 seconds. Therefore, a base station judges overload status by considering the 1-52 SAMSUNG Electronics Co., Ltd.

PART I. CallControl CDMA2000 1X/1xEV-DO BSS OPM/Ed.00overload status from both CMP and BSHX. (A higher load status is selected from the load status of CMP and BCP.) )))

1.4.1.5 Overload LevelThe load level of a processor is categorized into Normal level, Minor level, Major level, and Critical level. Each level is described below:

Normal level: System CPU usage is higher than the NORMAL_THRESHOLD value defined in PLD

Minor level: System CPU usage is higher than the MINOR_THRESHOLD value defined in PLD

Major level: System CPU usage is higher than the MAJOR_THRESHOLD value defined in PLD

Critical level: System CPU usage is higher than the CRITICAL_THRESHOLD value defined in PLD

1.4.2 Overload ControlOverload control and implementation features are described.

1.4.2.1 What is Overload ControlIf overload status continues, it will drastically affect the system. In the worst case, the system may be shut down. Therefore, an appropriate solution is required for overload to provide a continuous service and this kind of measure is called overload control.

1.4.2.2 FeaturesThe system is designed to maintain stable load status. In other words, when system load is increasing, it provides overload control for the current load level. When the load is decreasing, it maintains the previous load level for a certain period of time to maintain a stable load status. The threshold time of maintaining overload control is defined in PLD. The system executes an appropriate load control to provide a stable call service.

1.4.2.3 Overload Control MethodsOverload is controlled by either call service control or MS access control. Call service control is divided into manual mode call restriction and auto mode call restriction. The default of call restriction mode is auto mode. At this moment, BSC uses call service control and BCP uses both call service control and MS access control. SAMSUNG Electronics Co., Ltd. 1-53

Chapter 1. 1X CallControlAuto Mode Call RestrictionThe call processing block checks if there is system overload when a new call is created or registration is initiated. If there is overload, the block rejects a call creation request or registration if it exceeds the number of calls or registrations allowed for a specific time by referring to the threshold of corresponding load level. In addition, CMP overload control rejects a call (Origina-tion, Page_Response) creation request if it exceeds the number of accumulated calls.

Manual Mode Call RestrictionRegardless of system load level, call service is controlled by CALLCNT, REGCNT or PAGE_CNT which is configured by an operator.

Access Control of an MSIn the BCP overload control, a PSIST value is controlled to reduce the probability that an MS accesses the system. In other words, if a PSIST value is configured for each load level to send the PSIST of a corresponding overload level to an MS to reduce the probability that an MS accesses the system. The PSIST value is continuously sent to an MS through the overhead channel.

1.4.2.4 Overload ParameterAn operator can control system overload by configuring the following overload parameters: Overload parameters are described in the following table:

PART I. CallControl CDMA2000 1X/1xEV-DO BSS OPM/Ed.001.5 Call Count Check1.5.1 Overview

Call Count Check is used to check the number of busy subscribers in a base station and the number of busy subscribers of each call processing processor (CMP,CCP, or ATP) in an ACR. The number of busy subscribers in a base station is the same as the number of wireless resources allocated in a based station. Although a usual voice call service uses one traffic channel and one Walsh code channel for call setup, a handoff call can use more than one traffic channel and Walsh code channel according to conditions. In addition, a subscriber who uses data service can use more than one traffic channel. Therefore, the call count means the number of allocated Walsh code channels from the viewpoint of a base station. The call count is divided into a normal call and a data service call.

Chapter 1. 1X CallControl1.8 Load Sharing among FA in a Base Station1.8.1 Overview

The FA which an MS tries to access is allocated in a high priority. If the load of corresponding FA is higher than a specific threshold, an FA whose load is least is allocated. The load level is the ratio (percentage, %) of the current Tx Digital Gain vs. max. value of Tx Digital Gain of each subcell. An operator can control related parameters by using MMC and can apply different threshold to a voice call and a data call.

1.8.2 ProcedureIf it is necessary to allocate FA when there occurs a call, the FA which an MS tries to access is allocated if the following expression is satisfied. If it is not satisfied, an FA whose load is least is allocated.

Ovhd_CH_Tx_Gain+Voice_FDCH_Tx_Gain+Packet_FDCH_Tx_Gain+Initial_Tx_Gain< Load_Balancing_Thresh

The Ovhd_CH_Tx_Gain is the sum of Tx Digital Gain of the overhead channels for each subcell. This is calculated from the Tx Digital Gain DB index value of each overhead channel which is configured in PLD. The Voice_FDCH_Tx_Gain is the sum of Tx Digital Gain of FCH/DCCH which is allocated to a voice call for each subcell. This value is collected from each channel card, added in BCP, and the total sum is reported for each subcell. The Packet_FDCH_Tx_Gain is the sum of Tx Digital Gain of FCH/DCCH which is allocated to a data call for each subcell. This value is collected from each channel card, added in BCP, and the total sum is reported for each subcell. The Initial_Tx_Gain is the initial Tx Digital Gain of FCH or DCCH for a newly created call. This exits in PLD according to each radio configuration. The Load_Balancing_Thresh is a threshold that determines whether to allocate an FA with the least load for load balancing or to allocate the FA which an MS tries to access. Each different value is applied to a voice call and a data call.

In case of a handoff call, load balancing is not executed when a fixed FA is allocated. If various FAs can be allocated, an FA with the least load is allocated. This depends on handoff type or implementation method. If there is a preferred FA, it is allocated in the same manner as a newly created call by applying a threshold. An operator can make a preferred FA be allocated in high priority by configuring the threshold to 100 by using MMC. In addition, it is also possible to allocate an FA with the least load by configuring the threshold to 0. 1-66 SAMSUNG Electronics Co., Ltd.
