ETSI ETSI TS 132 508 V14.0.0 (2017-04)63GPP TS 32.508 version 14.0.0 Release 144 Architecture for multi-vendor plug-and-play 4.1 Functional architecture The functional architec

30、ture for multi-vendor plug-and-play connection of eNB to the network is described in 3GPP TS 32.501 4 clause 4.3.2. It covers the scenarios where eNB is connected to the Secure Operator Network either via an External Network or via a Non-Secure Operator Network. The entities (functional elements) in

31、volved in the PnC are listed and described in detail in clause 4.2. 4.2 Functional elements 4.2.1 IP Autoconfiguration services The IP Autoconfiguration services such as DHCP servers and Router Advertisements are used primarily to provide the eNB with basic IP configuration information (e.g. IP addr

32、ess, netmask, default gateway, domain name, IP address(es) of DNS servers, time servers). IP Autoconfiguration services may recognize the eNB as a client (using, for example, the vendor class identifier DHCP option) and provide with information such as IP address or FQDN of CA/RA server, IP address

33、or FQDN of SeGW, IP address or FQDN of EM, etc. The specific data formats used by IP Autoconfiguration services for multi-vendor plug-and-play procedures are described in 3GPP TS 32.509 5. From the multi-vendor plug-and-play feature perspective, the IP Autoconfiguration services may be categorized i

34、nto secure (those located within a Secure Operator Network) and public (those located either within a Non-Secure Operator Network or within an External Network). 4.2.2 DNS server DNS servers are used to resolve FQDNs into IP addresses. The FQDNs used for multi-vendor plug-and-play may be factory pro

35、grammed, provided by IP Autoconfiguration services, configured by EM, or derived/generated within the eNB using the vendor information, operator network domain name and name of the functional element. The specific FQDN formats used in multi-vendor plug-and-play procedures are described in 3GPP TS 32

36、.509 5. From the multi-vendor plug-and-play feature perspective, the DNS servers may be categorized into secure (those located within a Secure Operator Network) and public (those located either within a Non-Secure Operator Network or within an External Network). The DNS server is an optional functio

37、nal element and is only required if particular Operator deployment scenario relies on resolution of FQDNs (e.g. FQDNs are configured at the IP Autoconfiguration services, eNB and/or EM, while IP addresses are configured at DNS servers). 4.2.3 Certification Authority server The Certification Authorit

38、y server (CA/RA) is used in the in the multi-vendor plug-and-play procedures for security certificate enrolment (e.g. to provision operator certificates at the eNB using the factory-installed vendor certificates). There could be one or more CA/RA depending on a particular operator deployment scenari

39、o (e.g. one CA/RA per vendor). ETSI ETSI TS 132 508 V14.0.0 (2017-04)73GPP TS 32.508 version 14.0.0 Release 144.2.4 Element Manager (EM) The EM is a vendor-specific functional element that is used in multi-vendor plug-and-play procedures to provide the eNB with correct software and configuration inf

40、ormation. There could be one or more EM depending on a particular Operator deployment scenario (e.g. initial EM, serving EM). The configuration may contain an IP address or FQDN of (another) EM that this specific eNB shall use as EM. The configuration may contain an IP address or FQDN of (another) S

41、eGW that should be used before connecting to the EM. 4.2.5 Security Gateway (SeGW) The SeGW is used to establish a secure connection between the eNB and the Secure Operator Network. Depending on a particular operator deployment scenario, there could be separate SeGW for connection to the OAM network

42、 and to the CN. The OAM SeGW and CN SeGW may or may not be in practice separate physical entities. Depending on a particular operator deployment scenario, there could be more than one OAM SeGW (e.g. one per vendor).

43、cedure flows 5.1 High-level plug-and-connect The high level procedure for “multi-vendor plug-and connect“ is described next and illustrated in figure 5.1-1. Operators may deploy their management infrastructure in different ways. The following options are possible: - One or multiple EMs for each vend

44、or (e.g. an Initial EM and zero or more Serving EMs); - One or more SeGW (e.g. one SeGW for OAM and one or more for each CN, and/or one SeGW per vendor); - Zero or more IP Autoconfiguration services in the Secure Operator Network; - Zero or more DNS servers in the Secure Operator Network; - One or m

45、ore IP Autoconfiguration services in the External Network / non-Secure Operator Network; - Zero or more DNS servers in the External Network / non-Secure Operator Network; - One or more CA/RA (e.g. one per vendor). The procedure described in this clause applies to all deployment options listed above.

46、 The procedure begins when the eNB is powered up and ends when all mandatory steps in this procedure are completed or when an exception occurs. The pre-conditions for this procedure are: - The eNB is physically installed; - IP connectivity exists between involved telecom resources (functional elemen

47、ts listed in clause 4.2); - The involved telecom resources (functional elements listed in clause 4.2) are functional; - The relevant information is stored and available. The post-conditions for this procedure are: - One or more secure connection exists between eNB and EM and the Core Network(s); - V

48、ia the connection to the EM the eNB can receive further instructions to become operational and carry user traffic (e.g. the administrativeState is set to “unlocked“). The exceptions: - One of the steps outlined in the procedure fails. Procedure steps: 1) If a VLAN ID is available the eNB uses it. Ot

49、herwise the eNB uses the native VLAN where PnP traffic is sent and received untagged. 2) In this step eNB invokes the “Initial IP Autoconfiguration“ procedure (described in clause 5.2) and acquires its IP address through stateful or stateless IP Autoconfiguration. There may be additional information provided to the eNB. 3) In this step eNB invokes the “Certificate Enrolment“ procedure (described in clause 5.3). 4) In this step eNB invokes the “Establishing Secure Connection“ procedure (described in clause 5.4) and connects to the OAM SeGW.
