History

Purpose is to present the possible architectures of the mobile system. Clause 3 of this specification contains a definition of the different functional entities needed to support the mobile service. Clause 4 of this specification contains the configuration of a PLMN as well as the organization of the functional entities. Clause 5 of this specification contains a brief description of the interfaces involved which shows the principle of the organization considered.
