25、abbreviations 3.1 Definitions For the purposes of the present document, the terms and definitions given in TR 21.905 1 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905 1. Isolated E-UTRAN: either an E-UTRAN wi
26、thout normal connectivity with the EPC or deployed NeNBs with E-UTRAN functionality. Isolated E-UTRAN operation: Comprises two situations: 1) In the event of an interruption to normal backhaul connectivity Isolated E-UTRAN operation aims to adapt to the failure and maintain an acceptable level of ne
27、twork operation in the Isolated E-UTRAN. The restoration of service is the eventual goal. 2) Operation following the deployment of one or more Nomadic eNBs either without backhaul or with limited backhaul. Limited backhaul capability: Isolated E-UTRAN operation supports operation where the Isolated
28、E-UTRAN has no backhaul capability to the EPC. Furthermore Isolated E-UTRAN operation may have limited backhaul capability to the EPC. For the case of limited backhaul capability to the EPC only the signalling of public safety Ues can reliably be communicated to the EPC; in addition users may have t
29、he possibility to transmit a limited amount of user data with no guarantee of service. Nomadic eNB (NeNB): An NeNB is a nomadic cell and may consist: base station, antennas, microwave backhaul and support for local services. The NeNB is intended for Public Safety use providing coverage or additional
30、 capacity where: 1) coverage was never present (e.g. forest fire or underground rescue) or 2) where, for example, due to natural disaster coverage is no longer present.

32、 144 Overview 4.1 Service description Ensuring the continued ability of Public Safety users to communicate within mission critical situations is of the utmost importance. The Isolated E-UTRAN mode of operation provides the ability to maintain a level of communications for Public Safety users, via an
33、 eNB (or set of connected eNBs), following the loss of backhaul communications. The Isolated E-UTRAN mode of operation also provides the ability to create a serving radio access network without backhaul communications, from a deployment of one or more standalone Nomadic eNBs (NeNBs). In addition the
34、 Isolated EUTRAN feature also addresses the scenario where a fixed or nomadic set of eNBs is without normal backhaul communications but has been provided with an alternative (non-ideal) limited bandwidth backhaul. An Isolated E-UTRAN may comprise a deployment of one or more NeNBs. In this case opera
35、tor control would initiate Isolated E-UTRAN operation for a group of NeNBs in a given incident area. An Isolated E-UTRAN derived from NeNBs exhibits similar behaviour to an Isolated E-UTRAN derived from eNBs including: support for Public Safety Ues in the coverage area, communication between NeNBs a
36、nd support for limited backhaul connectivity. The Isolated E-UTRAN may comprise a single or multiple eNBs, a single or multiple NeNBs, or a mixed group of eNBs and NeNBs. An Isolated E-UTRAN comprising multiple (N)eNBs, with connections between the (N)eNBs, can provide communication between Ues acro
37、ss a wider area of coverage than can be provided by a single isolated (N)eNB. The Ues in the coverage of the Isolated E-UTRAN are able to continue communicating and provide a restricted set of services supporting voice, data and group communications, to their Public Safety users. An Isolated E-UTRAN
38、 is characterized by having no, or a limited, backhaul connection. In particular, the Isolated E-UTRAN feature enables services to be provided to Public Safety Ues in the following backhaul scenarios (see also Table 4.1-1): - No backhaul; - Limited bandwidth signalling only backhaul; - Limited bandw
39、idth signalling and user data backhaul.

42、eral requirements Isolated E-UTRAN operation shall not impact either GSM or UMTS. The use of Isolated E-UTRAN operation shall be authorized by the operator. The network controls the use of E-UTRAN resources used for Isolated E-UTRAN operation. When a Public Safety UE communicates within the Isolated
43、 E-UTRAN, the PLMN operator shall be able to collect accounting data for this communication. 5.2 Subscriber and service management requirements 5.2.1 Introduction (informative) In order to provide efficient Isolated E-UTRAN operation it is necessary that eNBs (and NeNBs) capable of forming and joini
44、ng an Isolated E-UTRAN are able to support certain functions locally thereby providing services of importance to the Public Safety community. 5.2.2 Requirements Public Safety Ues served only by an Isolated E-UTRAN will not possess user plane connectivity to an external IP network due to the absence
45、of backhaul connectivity to the Mobile Operator Network. The Isolated E-UTRAN may support Selected IP Traffic Offload at the Local Network, compatible with the service principles defined in 2, in order to provide connectivity to external IP networks (e.g. internet) when a backhaul connection (limite
46、d or otherwise) is present. The Isolated E-UTRAN shall be able to make use of a limited backhaul connection to exchange control plane signalling with the EPC. The Isolated E-UTRAN may use the limited backhaul connection to exchange user plane data with the EPC. NOTE: There is no quality of service e
47、xpectations for user plane data. The Isolated E-UTRAN shall support mobility for Public Safety Ues between the eNBs comprising the Isolated E-UTRAN. The Isolated E-UTRAN shall be able to establish local routing and ProSe Group Communication for the Public Safety Ues in coverage of the Isolated E-UTR
48、AN. The Isolated E-UTRAN shall be able to provide voice and data communications services to all Public Safety Ues and groups under the coverage of the Isolated E-UTRAN. The Isolated E-UTRAN shall allow Public Safety Ues under its coverage to initiate and maintain voice and data communications with o
49、ther Public Safety Ues and groups under the coverage of the Isolated E-UTRAN. The Isolated E-UTRAN shall be capable of informing served Public Safety Ues about which other Public Safety Ues the Isolated E-UTRAN is serving. The Isolated E-UTRAN shall support restrictions upon the provision of this information according to security policy. NOTE: For example, information on users within a served users organization could be sent to that served user, and information on users could be provided to other users within the same group. Lists of served users and/or serve
