34、l Report UMTS Universal Mobile Telecommunications System URS User Requirement Specification WAP Wireless Application Protocol4 User requirement specification 4.1 Introduction TETRA networks will rarely exist in isolation. These networks are built to enable communication between users of TETRA networ
35、ks and to/from other networks and network users. The present document describes the need to interface to existing and future networks mobile and fixed in order to enable interoperability of services and roaming between networks. There are two main classes of requirements: The interworking requiremen
36、ts are concerned with the ability to interface different networks so that higher level services and application are enabled when at least one of the parties is on a different network. The roaming requirements give users of a network the ability to access services when outside the area covered by the
37、ir subscribed network. There are roaming requirements for both voice services and data services. There are interworking requirements for both voice services and data services. ETSI ETSI TR 102 021-5 V1.2.1 (2010-12)8A specific TETRA network may need to interface with the following networks (not a co
38、mplete list): Another TETRA network. A GSM network. A GPRS network. A UMTS network. A Tetrapol network. Another mobile network. A fixed network (e.g. the PSTN). A private network (PABX). An private fixed IP network. The Internet. Other data networks. The basic requirement to enable interworking and
39、roaming are the interconnections between networks. TETRA networks will need to support the common interfaces to connect to GSM, PSTN and IP networks for voice, data and signalling. Figure 1: TMO Network Enhancements all workshop respondents from clause 5.1 in TR 102 621 i.2 In the TWC2007 Future of
40、TETRA workshop the different aspects of interworking and roaming were identified as important TMO Network enhancement areas, see the figure above from clause 5.1 in TR 102 621 i.2.

42、orking is the ability of multiple networks to co-operate and together render a service. It is an essential feature when parties involved in communication services are not connected to the same network. Those parties would typically be end-users in a voice communication. They could also be a client a
43、nd a server in an automated transaction. Users needs for voice interworking are expressed differently than user needs for data interworking. We will discuss each of them separately. 4.2.1 Voice interworking requirements Voice interworking is required between TETRA and other voice networks listed in
44、clause 4.1. Most TETRA voice communications are a combination of group calls and simplex and/or duplex “one to one“ calls. The interworking of duplex calls to PSTN, GSM and UMTS users, where most of the installed base of voice terminals are connected, is an essential requirement. There is growing in
45、terest to extend all TETRA voice services to users on mobile and fixed IP networks (Seamless Technology roaming in TR 102 621 i.2). The European Public Safety community has a specific requirement of interworking with Tetrapol networks. 4.2.2 Data interworking requirements Data interworking requireme
46、nts are of two main sorts: TETRA users wanting access to servers in other fixed or mobile networks; and users on other fixed or mobile networks wanting exchange of data with TETRA users. There are requirements for both. However, the possibility to access the outside world from the TETRA network stan
47、ds out as being the most important for all user segments. TETRA users will need access to the networks where the applications and other users are. This translates into: TETRA SDS, TETRA status, IP Packet Data, SMS, GPRS, 3G networks, APNs, WAP servers, intranets, the Internet. The TETRA community co
48、nsiders security and confidentiality as important requirements. It is important that interworking requirement do not have a negative impact on those, so the following should be considered: proper mechanisms such as firewalls need to be put in place in particular to control access from IP networks; a
49、nd flexible authorization mechanisms are needed, in particular the concept of call barring for data calls is required. 4.3 Roaming Roaming has implications on the terminal as well as on the SwMI. Here we consider the user requirements for the roaming service and therefore we do not make explicit distinction whether the implications are at the terminal level or at the SwMI level. Roaming between different TETRA networks is essential and by far the most important requirement. The Public Safety community is looking forward
