Setting Cell Parameters

IS-2000/IS-95 Cell Parameters

The following cell parameters are displayed under the Cell Parameters menu when the following two conditions exist:

1. The Operating Mode field is set to Active Cell (see Active Cell Operating Mode ), IS-2000 Test, or Cell Off, and
2. If Active Cell is the current operation mode, IS-2000 or IS-95 is selected in the System Type field.

• System ID (SID): A number uniquely identifying a wireless system. See also CALL[:CELL]:SIDentity )
• Network ID (NID): A number uniquely identifying a network within a wireless system. See also CALL[:CELL]:NIDentity .
• Escape Mode: See CALL[:CELL]:ESCape[:MODE] .
• Cell MCC: A part of the International mobile station identification (IMSI) identifying the home country. See also CALL[:CELL]:MCCode<[:SELected]|:TA2000> .
• Cell MNC: A part of the IMSI identifying the home network within the home country. See also CALL[:CELL]:MNCode .
• Max Slot Cycle Index. (see CALL:PAGing:SCINdex[:MAXimum] )
• RL Traffic to Pilot Gain (RLGAIN_TRAFFIC_PILOT): See CALL[:CELL]:RLGain[:TTPilot] . This setting is only for IS-2000 system RC3 and above. It is used to range the test set's receiver (see Equation C ).
• Paging Data Rate ( CALL:PAGing:DRATe ): This parameter is shown in this menu when IS-95 system is selected. To set this parameter in IS-2000 system, see Setting Control Channel Parameters .
• Base ID ( CALL:BIDentity ): It represents the identification number of the base station. It can be changed at any time and sent to the mobile station in the next overhead messages ( System Parameters Message , or ANSI-41 System Parameters Message , or MC-RR Parameters Message ). The mobile station may use this parameter together with other overhead message parameters (such as SID, NID, etc.) to identify the presence of a particular User Zone.
• Maximum Number of Alternative SO ( CALL[:CELL]:SOPTion:ALTernate:COUNt[:MAXimum] ): The parameter represents the maximum number of alternative service options that the mobile station is allowed to include in the origination message or the Page Response Message (PRM). The test set send this parameter to the mobile station in the broadcast messages.
• Flexible RC/SO Negotiation Mode ( CALL[:CELL]:CONTrol:RCSO:NEGotiation:FLEXible[:MODE] ): The parameter determines whether the test set performs flexible RC/SO matching between the signaling message of the mobile station and the RC/SO setting of the test set. The value of the parameter can be changed during an active call and the new value will be used when establishing the next call.

  When the RC or SO is not matched between the test set and the mobile station, the test set will use the following RC/SO matching algorithms:

  • If the setting is set to Off , only the SERVICE_OPTION and FOR/REV_RC_PREF in ORM/PRM are used to match the test set's user settings when establishing a call under IS-95/IS-2000 systems.
  • If the setting was set to On , there will be more flexibility when matching test set's RC/SO user settings with mobile's by taking ALT_SO and FOR/REV_FCH_RC_MAP in the ORM/PRM into consideration as below:
    • For SO matching, the test set's SO user setting will be find in both SERVICE_OPTION and ALT_SOs (if included).
    • For RC matching, the test set's F/R-RC user setting will be find in both FOR/REV_RC_PREF and FOR/REV_FCH_RC_MAP (if included).
• General Extension Message (GEM) Support: The parameter determines whether the test set can send the layer 3 messages (ECAM/MECAM or UHDM/MUHDM) together with the Radio Configuration Parameters Message (RCPM) to the MS using the General Extension Message (GEM). See more details in 3.7.2.3.2.44 General Extension Message in 3GPP2 C.S0005 (Revision E). See also CALL:CELL:GEMessage:SUPPort[:ENABle] .

  General Extension Message Support is only applicable when Operating Mode is Active Cell , System Type is IS-2000 , and IS-2000 Radio Configuration is RC6 (Fwd11, Rev8). If the setting is changed when it is inapplicable, the value will be saved yet takes no effect until it is applicable again.

  If GEM Support is applicable and set to On , the test set will

  • send ECAM (Extended Channel Assignment Message) or MECAM (MEID Extended Channel Assignment Message) together with RCPM parameters using GEM during call establishment procedure.
  • send UHDM (Universal Handoff Direction Message) or MUHDM (MEID Universal Handoff Direction Message) together with RCPM parameters using GEM during handoff procedure.

  If GEM is set to Off , the test set will send RCPM and ECAM/MECAM or UHDM/MUHDM separately to the MS during call establishment or handoff procedures.

     

  NOTE

  The GEM setting can only be changed when Call Status is Idle . If it is changed during the call, it will cause the error +254 "CDMA call processing error; Operation not allowed due to call status not idle"
