12.1.2 Timers on the network side
No timers are defined on the network side in this version of this specification.
12.2 Other system parameters
12.2.1 TCP related parameters and system parameters
TCP port for Discovery is port number 14001.
TCP port for Registration is port number 14001.
The MS should ensure that the small packets containing each signalling message are sent immediately. For example, this can be done by using the standard TCP socket options (e.g., TCP_NODELAY to disable Nagle’s algorithm).
The MS shall not normally release the TCP connection to the GANC, while it is registered with a GANC.
Once the TCP connection is released, the IPsec tunnel can also be released unless this tunnel will be used for subsequent registration.
