Introduction Network sharing is a way for operators to share the heavy deployment costs for mobile networks, especially in the roll-out phase. In the current mobile telephony marketplace, fu

27、nctionality that enables various forms of network sharing is becoming more and more important. These aspects have not really been addressed before Release 6 in 3GPP UTRAN based access networks, before Release 8 in 3GPP E-UTRAN based access networks and before Release 10 in 3GPP GERAN based access ne

28、tworks, although there has been functionality that supports a very basic type of network sharing since the Release 5 versions of the 3GPP specifications. To cope with 3GPP pre-Release 6 UTRAN UEs and with non supporting 3GPP GERAN UEs, this specification describes extra functionality for MSCs, SGSNs

29、, BSCs and RNCs in order to provide network sharing functionality to “non-supporting UEs“. In this Release of the specifications, all UTRAN and E-UTRAN capable UEs are required to support the UTRAN and E-UTRAN network sharing requirements. Hence the E-UTRAN and MMEs (which were introduced in 3GPP Re

30、lease 8) do not need functionality to handle “non-supporting UEs“. Scenarios and user requirements are described in TR 22.951 1, while the current document presents the stage 2 details and descriptions of how these requirements are supported in a 3GPP GERAN, UTRAN and/or E-UTRAN based network. ETSI

31、ETSI TS 123 251 V14.0.0 (2017-05)63GPP TS 23.251 version 14.0.0 Release 141 Scope The present document covers the details of Network Sharing for GERAN, UTRAN and E-UTRAN. It shows how several core network operators can share one radio access network and details the impacts on the network architectur

32、e. All UEs shall comply with existing requirements, among them PLMN selection and system information reception.

44、itions and abbreviations 3.1 Definitions For the purposes of the present document, the following terms and definition below apply. Terms and definitions not defined below can be found in TR 21.905 2. Conventional network: A PLMN consisting of radio access network and core network, by which only one

45、serving operator provides services to its subscriber. Subscribers of other operators may receive services by national or international roaming. Common PLMN: The PLMN-id indicated in the system broadcast information as defined for conventional networks, which non-supporting UEs understand as the serv

46、ing operator. Core network operator: An operator that provides services to subscribers as one of multiple serving operators that share at least a radio access network. Each core network operator may provide services to subscriber of other operators by national or international roaming. Gateway Core

47、Network: A network sharing configuration in which parts of the core network (MSCs/SGSNs/MMEs) are also shared. Multi-Operator Core Network: A network-sharing configuration in which only the RAN is shared. Non-supporting UE: A UE that does not support network sharing in the sense that it ignores the

48、additional broadcast system information that is specific for network sharing for 3GPP UTRAN and GERAN. In other specifications, the term “network sharing non-supporting UE“ may be used. Supporting UE: A UE that supports network sharing in the sense that it is able to select a core network operator a

49、s the serving operator within a shared network. In other specifications, the term “network sharing supporting UE“ may be used. Anchor PLMN: With regard to SRVCC from CS to PS, this Anchor PLMN points to the PS domain operator in which the voice media is anchored in Access Transfer Gateway as part of the SRVCC procedure.
