Subject: [PATCH] Proposal for a "channel request" interface...
Reuqests for a subscriber a stored within the gsm_subscriber
datastructure and it will keep track how many channels are
allocated for this user and of which type to decide on policy...
e.g. attempt to submit SMS during a phone call and not doing
paging but a simple (immediate) assignment of the channel...
