rename gsm_subscriber_connection to ran_conn In preparation for inter-BSC and inter-MSC handover, we need to separate the subscriber management logic from the actual RAN connections. What better time to finally rename gsm_subscriber_connection. * Name choice: In 2G, this is a connection to the BSS, but even though 3GPP TS commonly talk of "BSS-A" and "BSS-B" when explaining handover, it's not good to call it "bss_conn": in 3G a BSS is called RNS, IIUC. The overall term for 2G (GERAN) and 3G (UTRAN) is RAN: Radio Access Network. * Rationale: A subscriber in the MSC so far has only one RAN connection, but e.g. for inter-BSC handover, a second one needs to be created to handover to. Most of the items in the former gsm_subscriber_connection are actually related to the RAN, with only a few MM and RTP related items. So, as a first step, just rename it to ran_conn, to cosmetically prepare for moving the not strictly RAN related items away later. Also: - Rename some functions from msc_subscr_conn_* to ran_conn_* - Rename "Subscr_Conn" FSM instance name to "RAN_conn" - Rename SUBSCR_CONN_* to RAN_CONN_* Change-Id: Ic595f7a558d3553c067f77dc67543ab59659707a
