ETSI ETSI TS 122 346 V13.0.0 (2016-03)53GPP TS 22.346 version 13.0.0 Release 131 Scope The present document specifies the service requirements for Isolated E-UTRAN Operation in support of mission c

22、ritical network operation for Public Safety. In particular, requirements are specified for: - Initiation of Isolated E-UTRAN operation. - Ongoing Isolated E-UTRAN operation. - Termination of Isolated E-UTRAN operation. - Security aspects of Isolated E-UTRAN operation. 2 References The following docu

23、ments contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. -

A term defined in the present document takes precedence over the

26、definition of the same term, if any, in TR 21.905 1. Isolated E-UTRAN: either an E-UTRAN without 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 Iso

27、lated E-UTRAN operation aims to adapt to the failure and maintain an acceptable level of network 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. Lim

28、ited backhaul capability: Isolated E-UTRAN operation supports operation where the Isolated 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

29、 of public safety Ues can reliably be communicated to the EPC; in addition users may have the 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

30、local services. The NeNB is intended for Public Safety use providing coverage or additional 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、NB Nomadic eNB 4 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 u

33、sers, via an 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

34、addition the 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 thi

35、s case operator 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 bet

36、ween NeNBs and 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 betw

37、een Ues across 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 Isol

38、ated E-UTRAN 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; - L

42、ents 5.1 General 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

43、the Isolated 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 formi

44、ng and joining 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

45、the absence 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 connec

46、tion (limited 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

47、of service expectations 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 Is

48、olated E-UTRAN. 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 communica

49、tions with other 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.
