The present document specifies the protocol conformance testing for the 3GPP UE connecting to the 5G System (5GS) via its radio interface(s). The following information can be found in the present document (first part of a multi-part test specification): - the overall test structure; - the test configurations; - the conformance requirement and references to the core specifications; - the test purposes; and - a brief description of the test procedure, the specific test requirements and short message exchange table. The applicability of the individual test cases is specified in the ICS proforma specification (3GPP TS 38.523-2 [2]). The Test Suites are specified in part 3 (3GPP TS 38.523-3 [3]). The present document is valid for UE implemented according to 3GPP Releases starting from Release 15 up to the Release indicated on the cover page of the present document.
Recent world events have created a heightened social focus on public protection and general public safety. Actions such as the Universal Service Directive requiring the European emergency call number (112) to be enhanced with the provision of caller location and the Seveso II Directive aimed at the prevention of major accidents involving dangerous substances highlight this focus. Special consideration may have to be given to the elderly, the disabled and the young people. An annotated bibliography of documents dealing with human factors can be found in ETSI SR 001 996. The provision of effective communication is one of the most important duties of a public authority towards its citizens. An important component required to meet this duty is the ability for Authorities to communicate with citizens during times of emergency. Authorities and emergency response teams need to warn and inform the public in times of crisis and therefore is required to have effective, high quality communication methods and systems to meet this need. The responsibility for emergency response or disaster-related communications is addressed differently from country to country. In most cases, the parties responsible for warning and informing the public follow the country's administrative structures with coordinators at both the local and national levels, as well as across multiple disciplines and departments. The present document catalogues the requirements on warning and informing the public as seen by the Emergency Services Community and looks at the technologies and methods available to do this, and also addresses IoT devices that act upon receiving a (specific) warning message.
The frequency bands used for broadcasting below 30 MHz are: •Low Frequency (LF) band: from 148,5 kHz to 283,5 kHz, in ITU Region 1 [1] only; •Medium Frequency (MF) band: from 526,5 kHz to 1 606,5 kHz, in ITU Regions 1 [1] and 3 [1] and from 525 kHz to 1 705 kHz in ITU Region 2 [1]; •High Frequency (HF) band: a set of individual broadcasting bands in the frequency range 2,3 MHz to 27 MHz, generally available on a Worldwide basis. These bands offer unique propagation capabilities that permit the achievement of: •large coverage areas, whose size and location may be dependent upon the time of day, season of the year or period in the (approximately) 11 year sunspot cycle; •portable and mobile reception with relatively little impairment caused by the environment surrounding the receiver. There is thus a desire to continue broadcasting in these bands, perhaps especially in the case of international broadcasting where the HF bands offer the only reception possibilities which do not also involve the use of local repeater stations.
Mobile and fixed networks are evolving towards ultra-broadband and, with 5G, are going to converge. The use of much broader frequency ranges, up to 60 GHz, where radio propagation is an issue, is going to impact the network deployment topologies. In particular, the use of higher frequencies and the need to cover hot/black spots and indoor locations, will make it necessary to deploy much denser amount of radio nodes. 5G is introducing major improvements on Massive MIMO, IoT, low latency, unlicensed spectrum, and with V2x for the vehicular market. Support of some of these services will have a relevant effect on the power ratings and the energy consumption at the radio base station. A major new service area of 5G impacting the powering and backup will be the URLLC (Ultra Reliable Low Latency Communication) as its support will increase the service availability demands by many orders of magnitude. Supporting such high availability goals will be partly reached through redundant network coverage, but a main support will have to come through newly designed powering architectures. This will be made even more challenging as 5G will require the widespread introduction of distributed small cells. ETSI TS 110 174-2-2 [i.5] analyses the implications and indicates possible solutions to fulfil such high demanding availability goals. There is a need to define sustainable and smart powering solutions, able to adapt to the present mobile network technologies and able to evolve to adapt to their evolution. The flexibility would be needed at level of power interface, power consumption, architecture tolerant to power delivery point changes and including control-monitoring. This means that it should include from the beginning appropriate modularity and reconfiguration features for local powering and energy storage and for remote powering solutions including power lines sizing, input and output conversion power and scalable sources. The present document was developed jointly by ETSI TC EE and ITU-T Study Group 5. It is published respectively by ITU and ETSI as Recommendation ITU-T L.1210 [i.7] and ETSI ES 203 700 (the present document), which are technically-equivalent.
