The circuit mode data services and Internet Protocol (IP) issues are outside the scope of this ETS. T

12、he information exchange about address mapping between the TETRA air interface address and any external data network address due to migration between TETRA SwMIs is outside the scope of this gateway standard. The gateway functions are defined as required by the used upper network layer protocol and a

13、re outside the scope of this standard. 2 Normative references This ETS incorporates by dated and undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subseque

14、nt amendments to or revisions of any of these publications apply to this ETS only when incorporated in it by amendment or revision.

20、ction Oriented Network Protocol (CONP); - Connectionless Network Protocol (CLNP); - This ETS considers the X.25 packet data gateway and related issues. As a part of data transmission path a TETRA SwMI could behave seen from the external network as a data terminal or as a data network node. In both c

21、ases a TETRA user equipment identification Individual TETRA Subscriber Identity (ITSI) or Group TETRA Subscriber Identity (GTSI) is associated with an X.25 address known by the external network, see ETS 300 392-1 l, clause 7, Network Service Access Point (NSAP) addressing. This association or bindin

22、g may be static or dynamic. Specific ConnectionLess Network Service (SCLNS). 5 Data network gateways 5.1 X.25 and X.75 gateway A TETRA SwMI shall be connected to a X.25 network as a X.25 network node. ITU-T Recommendation X.35 3 should be used as a guide in design of interface to PDNs. The SwMI shal

23、l act as a data node on the X.25 network and the protocol defined in ITU-T Recommendation X.75 4 shall be used for interworking purposes. 5.2 Specific ConnectionLess Network Service (SCLNS) The SCLNS as defined in ETS 300 392-2 2, clause 26 as such is a sub-network access protocol and requires an up

24、per network layer provided by other network layer protocols. A full version of this service is bound to the TETRA domain although some of the facilities may be mapped against other network protocols in the gateway e.g. time stamping, see ETS 300 392-2 2, subclause 27.2.1. 6 Address mapping The TETRA

25、 networks use addresses as defined in ETS 300 392-1 I, clause 7. TETRA air interface addressing and external data networks addressing are inherently different although TETRA address construction is the same as used in other land mobile systems and e.g. country code values may be same. For that reaso

26、n an address mapping is required between TETRA and external networks. The address mapping inside TETRA network should follow the same principles as defined in ITU-T Recommendation X.31 5 for the X.25 service. in effect the TETRA air interface address should be a sub-network address limited to the TE

27、TRA domain.
