Movement of PS in NEAX2400 IPX
PCS Community
The SYS-ID is a unique ID which was given in order to manage the PCS system. The area where the SYS-ID is
effective is called PCS Community. Every PCS Community in a FCCS network is given a unique PCS Community
Number (PCN). Each PCN has its own SYS-ID. The PCN is used in stead of the SYS-ID for MAT command, and
this can reduce the effect upon changing the SYS-ID to some measure. The habitual operation of the SYS-ID, which
reaches to nine digits for the management purpose, is not needed; therefore easy maintenance can be provided. A
single PCS Community can be assigned in multiple nodes, and a single node can belong to multiple PCS
Communities by using the Tenant service.
PS movement in the NEAX2400 IPX system is classified into four kinds as described below:
1. Stand-by condition movement
Movement of an idle PS within the home PCN area in the home FCCS network (in the FCCS network
accommodating the home node). The event of PS Location Registration occurs only when the PS moves
over the Calling area. Even if a PS is in the Intra-FCCS Roaming or Roaming status, movement of the PS
within the current PCN is also stand-by condition movement. In the NEAX2400 IPX system, the home
PCN can be assigned over the node, however the Calling Area cannot. Because of this, the event of PS
Location Registration occurs whenever an idle PS moves over the node.
2. Hand-Over
Movement of a PS engaged in communication within the home PCN area in the home FCCS network. The
event of Hand-Over occurs regardless of the Calling Area.
Even if a PS is in the Intra-FCCS Roaming or Roaming status, movement of the PS engaged in
communication within the current PCN is also Hand-Over. In the NEAX2400 IPX system, the call
engaged in communication is supported even in the case of Hand-Over over the node.
3. Intra-FCCS Roaming
Effective only in the home FCCS network. Roaming Request is made to the home node whenever
Roaming occurs out of the home FCCS network. This pattern simplifies the internal operation. The call
engaged in communication is not supported.
4. Roaming
PS Location Registration to the ZT in another PCN than the home PCN is called Roaming. The call
engaged in communication is not supported.
