09.053GPPInterworking between the PLMN and the PSPDN for PAD AccessTS

The present document identifies the interworking functions and requirements to support Packet Assembly/Disassembly (PAD) services in the PLMN.

GSM 09.05 applies to PAD access in order to provide communications with host systems connected to Packet Switched Public Data Network (PSPDN) for Mobile Stations (MS)s.

Within the present document, the requirements for accessing an existing PAD in a PSPDN (basic PAD access) or accessing a dedicated PAD are considered separately. In each case, the general problem of charging is examined.

The present document considers only the access by a MS to a PAD and not the reverse access (i.e. only mobile originated calls are supported).
