Such command corresponds to the BSD socket routine. Up to 7 sockets can be created. It is possible tospecify the local port to bind within the socket in order to send data from a specific port. The bind functionalityis supported for both TCP and UDP sockets.The socket creation operation can be performed only after the PDP context activation on one of thedefined profiles.
