It may be possible to deactivate Sleep Mode using the application interface to the SS.
Sleep Mode is a function that is used to enable Subscriber Stations to conserve power. In Sleep Mode, the SS becomes unavailable for predetermined periods. This minimizes the SS power usage. The periods of absence are negotiated with the serving BS.
The E6651A supports both BS and SS initiated Sleep Mode. The power saving class supported is defined below:
Power Save Class 1 - the sleep window is exponentially increased from a minimum value to a maximum value. This is typically done when the MS is doing best-effort and non-real-time traffic.
The Sleep Mode menu has 2 levels. Press Mode, BS Emulator, Protocol FN Test, Sleep Mode to access it. You must also indicate to the SS that the BS supports Sleep Mode by selecting Mobility Negotiation, Sleep-mode Support [ON] in the BSE Setting menu. (Mode, BS Emulator, Settings, BSE Setting, More, More, More, More).
For more details of the Sleep Mode configuration menu and associated API commands click Sleep Mode Functions.
It is possible to initiate Sleep Mode from the E6651A. Once the SS is in sleep mode, the E6651A can de-activate and the SS returns to normal operation.
Configure BS Initiated Sleep Mode as follows:
Press Mode, BS Emulator, Settings, BSE Setting, More, More, More, More, Mobility Negotiation and press Sleep-Mode Support to select [ON] to indicate that the BS supports Sleep Mode.
Press Mode, BS Emulator, Settings, BSE Setting, REP-REQ, REP-REQ msg. to select [OFF].
Connect to the SS by performing the Network Entry procedure.
Press Mode, BS Emulator, Settings, BSE Setting, More, More, More, Connection Timeout to select [OFF].
Press Mode, BS Emulator, Protocol FN Test, Sleep Mode, Sleep Initiated set to [BS]. (Default)
Press Mode, BS Emulator, Protocol FN Test, Sleep Mode, MOB_SLP-RSP, Operation set to [Activation].
Press Mode, BS Emulator, Protocol FN Test, Sleep Mode, and press Send MOB_SLP-RSP to send this message to the SS and activate Sleep Mode.
Confirm SLP-RSP on the E6651A traffic display (and if connected, the N6421A logged data). In the Subscriber Station information area of the E6651A display, note that the state has changed to Sleep. The application interface to the SS may also show the sleep state.
You can now test that the SS returns to normal operation when the BS deactivates Sleep Mode. Set the following:
Press Mode, BS Emulator, Protocol FN Test, Sleep Mode, MOB_SLP-RSP, Operation set to [Deactivation].
Press Mode, BS Emulator, Protocol FN Test, Sleep Mode, and press Send MOB_SLP-RSP to send this message to the SS and deactivate Sleep Mode.
Confirm SLP-RSP on the E6651A traffic display (and if connected, the N6421A logged data). In the Subscriber Station information area of the E6651A display, note that the state has changed to Connected.

This procedure details the steps required to initiate Sleep Mode from the SS.
Configure SS Initiated Sleep Mode as follows:
Press Mode, BS Emulator, Settings, BSE Setting, More, More, More, More, Mobility Negotiation and press Sleep-Mode Support to select [ON] to indicate that the BS supports Sleep Mode.
Press Mode, BS Emulator, Settings, BSE Setting, REP-REQ, REP-REQ msg. to select [OFF].
Connect to the SS by performing the Network Entry procedure.
Press Mode, BS Emulator, Settings, BSE Setting, More, More, More, Connection Timeout to select [OFF].
Press Mode, BS Emulator, Protocol FN Test, Sleep Mode, Sleep Initiated set to [SS] to configure the E6651A to respond to Sleep Mode requests from the SS.
Using the SS control interface, enable Sleep Mode for the device being tested.
Confirm SLP-REQ and SLP-RSP on the E6651A traffic display (and if connected, the N6421A logged data). In the Subscriber Station information area of the E6651A display, note that the state has changed to Sleep. The application interface to the SS may also show the sleep state.
You can now test that the SS returns to normal operation when the BS deactivates Sleep Mode. Set the following:
Press Mode, BS Emulator, Protocol FN Test, Sleep Mode, MOB_SLP-RSP, Operation set to [Deactivation].
Press Mode, BS Emulator, Protocol FN Test, Sleep Mode, and press Send MOB_SLP-RSP to send this message to the SS and deactivate Sleep Mode.
Confirm SLP-RSP on the E6651A traffic display (and if connected, the N6421A logged data). In the Subscriber Station information area of the E6651A display, note that the state has changed to Connected.

Description |
Default |
API Command |
|
Press Initial Sleep Window to set the Initial Sleep Window value in the MOB_SLP-RSP message. (The requested start value in frames for the first sleep interval). |
10 |
||
|
Press Listening Window to set the Listening Window value in the MOB_SLP-RSP message. (The number of frames the MS should remain in a listen state after the first sleep interval). |
5 |
||
|
Press MOB_SLP-RSP to access the message configuration menu. |
X |
None | |
|
Press Operation to set MS sleep mode Activation or Deactivation in the MOB_SLP-RSP message. |
Deactivation |
||
|
Press Send MOB_SLP-RSP to send the MOB_SLP-RSP message to the MS. If the Operation is set to Deactivation, sending this message deactivates sleep mode and the SS returns to normal operation. If the Operation is set to Activation, sending this message places the SS into Sleep Mode. |
X |
||
|
Press Sleep Initiated to set BS or MS. If MS is selected, the E6651A responds to Sleep Mode requests from the SS. Configures the E6651A to send MOB_SLP-RSP when MOB_SLP-REQ is received from the Subscriber Station. |
Base Station |
||
|
Press to access the Sleep Mode configuration menus. |
X |
None | |
|
Press Window Base to set the sleep mode final window base value in the MOB_SLP-RSP message. This base value is used with the final sleep window exponent to determine the final sleep window value. |
10 |
||
|
Press Window Exponent to set the sleep mode final window exponent value. This specifies the multiplying factor used to determine the final sleep window value. |
