In detailed configuration mode of mobile settings, you can control a mobile connection by specifying the connection time and the connection count.

Setting examples

• I want to automatically swith the SIM to the other one if the communication is interrupted
• Can I set the order of priority for wired and wireless (SIM) connections?

In this article, the items indicated by the connection time and the connection count are explained with illustrations.

▌  Controlling connection of a mobile line

"Connection waiting time", "Call waiting time", and "Line connection retry count" are used when connecting to a mobile line.

The following figure shows at which timing each item is used when connecting to a line

amnimo(cfg)# mobile peer MOB-PEER-NAME
amnimo(cfg-mp-MOB-PEER-NAME)# session SESSION-NAME
amnimo(cfg-mps-SESSION-NAME)# attach-timeout Na   ←Specify the connection wait time
amnimo(cfg-mps-SESSION-NAME)# call-timeout Nc1     ←Specify the call wait time
amnimo(cfg-mps-SESSION-NAME)# retry Nr1           ←Specify the line connection retry count

▌  Controlling disconnection of a mobile line when no-communication detection time expires

If you set the "no-communication detection time", when a no-communication state continues, disconnecting a mobile line will be controlled.

• This function has been disabled by default. If you want to enable it, set it in detailed configuration mode.  

amnimo(cfg)# mobile peer MOB-PEER-NAME
amnimo(cfg-mp-MOB-PEER-NAME)# session SESSION-NAME
amnimo(cfg-mps-SESSION-NAME)# idle-timeout Ni     ←Specify the no-communication detection time

▌  Controlling disconnection of a mobile line when the maximum connection time expires

The "maximum connection time" setting will control disconnection of the mobile line if the line remains connected during the specified time period.

• This function has been disabled by default. If you want to enable it, enable it in detailed configuration mode.
• The line connection process in the figure shows the attach process and the authentication process.

amnimo(cfg)# mobile peer MOB-PEER-NAME
amnimo(cfg-mp-MOB-PEER-NAME)# session SESSION-NAME
amnimo(cfg-mps-SESSION-NAME)# connection-timeout Nc2       ←Specify the maximum connection time

▌  Controlling the reconnection waiting time of a mobile line

The "reconnection waiting time" setting controls to maintain the connection state without disconnecting the line within a set time period in case where communication with the base station cannot be performed temporarily.

• This is a function used for improving the stability of communication, by reducing the overhead related to the connection processing that occurs when reconnecting the line after it is disconnected by maintaining the line connection state within the set period.
• If the line cannot be reconnected within the set period, the line will be disconnected.
• By specifying "no reconnect-timeout" in detailed configuration mode, you will be able to control disconnection of the line immediately when communication with the base station is detected as disconnected.

amnimo(cfg)# mobile peer MOB-PEER-NAME
amnimo(cfg-mp-MOB-PEER-NAME)# session SESSION-NAME
amnimo(cfg-mps-SESSION-NAME)# reconnect-timeout Nr2        ←Specify the reconnection wait time
amnimo(cfg-mps-SESSION-NAME)# no reconnect-timeout        ←If disabling the function

▌  Controlling disconnection of a mobile line by the disconnection detection function

The "disconnection detection function" setting will control the line to be disconnected if the RSSI value becomes less than or equal to the specified value for more than the specified time period.

• By specifying "no disconnect-detection" in detailed configuration mode, you will be able to control not to disconnect the line even when radio waves cannot received.
• However, when disconnecting the line from the base station or authentication server, this function will not be applied. In this case, the line will be disconnected if it cannot be reconnected within the reconnection wait time, and the line will be switched if multiple sessions are set.

amnimo(cfg)# mobile peer MOB-PEER-NAME
amnimo(cfg-mp-MOB-PEER-NAME)# session SESSION-NAME
amnimo(cfg-mps-SESSION-NAME)# disconnect-detection rssi Nrssi time Ntime      ←Specify the disconnection detection function
amnimo(cfg-mps-SESSION-NAME)# no disconnect-detection     ←If disabling the function
