The purpose of this TS is to present the possible architectures of the mobile system. Clause 3 of this TS contains a definition of the different functional entities needed to support the mobile service.

In clause 4, the configuration of a PLMN is described as well as the organisation of the functional entities; the configuration presented is the most general in order to cope with all the possible implementations which can be imagined in the different countries. To illustrate that purpose, some examples of possible configurations are presented.

Clause 5 of this TS contains a brief description of the interfaces involved which shows the principle of the organisation considered.
