C.3 Target ID

23.0033GPPNumbering, addressing and identificationRelease 18TS

This clause describes a possible way to support SRNS relocation.

In UMTS, when SRNS relocation is executed, a target ID which consists of MCC, MNC and RNC ID is used as routeing information to route to the target RNC via the new SGSN. An old SGSN shall resolve a new SGSN IP address by a target ID to send the Forward Relocation Request message to the new SGSN.

It shall be possible to refer to a target ID by a logical name which shall be translated into an SGSN IP address to take into account inter-PLMN handover. The old SGSN transforms the target ID information into a logical name of the form:

rncXXXX.mncYYY.mccZZZ.gprs

X shall be Hex coded digits; Y and Z shall be encoded as single digits (in the range 0-9). If there are less than 4 significant digits in XXXX, one or more "0" digit(s) is/are inserted at the left side to fill the 4 digits coding. If there are only 2 significant digits in YYY, a "0" digit is inserted at the left side to fill the 3 digit coding. Then, for example, a DNS server is used to translate the logical name to an SGSN IP address.

As an example, the logical name for RNC 1B34, MCC 167 and MNC 92 will be coded in the DNS server as:
rnc1B34.mnc092.mcc167.gprs

Annex D (informative):
Applicability and use of the ".3gppnetwork.org" domain name

There currently exists a private IP network between operators to provide connectivity for user transparent services that utilise protocols that rely on IP. This includes (but is not necessarily limited to) such services as GPRS/PS roaming, WLAN roaming, GPRS/PS inter‑PLMN handover and inter‑MMSC MM delivery. This inter‑PLMN IP backbone network consists of indirect connections using brokers (known as GRXs – GPRS Roaming Exchanges) and direct inter‑PLMN connections (e.g. private wire); it is however not connected to the Internet. More details can be found in GSMA PRD IR.34 [57].

Within this inter‑PLMN IP backbone network, the domain name ".gprs" was originally conceived as the only domain name to be used to enable DNS servers to translate logical names for network nodes to IP addresses (and vice versa). However, after feedback from the Internet Engineering Task Force (IETF) it was identified that use of this domain name has the following drawbacks:

1. Leakage of DNS requests for the ".gprs" top level domain into the public Internet is inevitable at sometime or other, especially as the number of services (and therefore number of nodes) using the inter‑PLMN IP backbone increases. In the worst case scenario of faulty clients, the performance of the Internet’s root DNS servers would be seriously degraded by having to process requests for a top level domain that does not exist.

2. It would be very difficult for network operators to detect if/when DNS requests for the ".gprs" domain were leaked to the public Internet (and therefore the security policies of the inter‑PLMN IP backbone network were breached), because the Internet’s root DNS servers would simply return an error message to the sender of the request only.

To address the above, the IETF recommended using a domain name that is routable in the pubic domain but which requests to it are not actually serviced in the public domain. The domain name ".3gppnetwork.org" was chosen as the new top level domain name to be used (as far as possible) within the inter‑PLMN IP backbone network.

Originally, only the DNS servers connected to the inter‑PLMN IP backbone network were populated with the correct information needed to service requests for all sub‑domains of this domain. However, it was later identified that some new services needed their allocated sub‑domain(s) to be resolvable by the UE and not just inter-PLMN IP network nodes. To address this, additional, higher‑level sub‑domains were created:

– "pub.3gppnetwork.org", which is to be used for domain names that need to be resolvable by UEs (and possibly network nodes too) that are connected to a local area network that is connected to the Internet; and

– "ipxuni.3gppnetwork.org", which is to be used for domain names for UNI interfaces that need to be resolvable by UEs that are connected to a local area network that is not connected to the Internet (e.g. local area networks connected to the inter-PLMN IP network of the IPX).

Therefore, DNS requests for the above domain names can be resolved, while requests for all other sub‑domains of "3gppnetwork.org" can simply be configured to return the usual DNS error for unknown hosts (thereby avoiding potential extra, redundant load on the Internet’s root DNS servers).

The GSM Association is in charge of allocating new sub‑domains of the ".3gppnetwork.org" domain name. The procedure for requesting new sub‑domains can be found in Annex E.

Annex E (normative):
Procedure for sub‑domain allocation

When a 3GPP member company identifies the need for a new sub‑domain name of ".3gppnetwork.org", that 3GPP member company shall propose a CR to this specification at the earliest available meeting of the responsible working group for this TS. The CR shall propose a new sub‑domain name. The new sub‑domain proposed shall be formatted in one of the formats as described in the following table.

Sub‑domain Format

Intended Usage

<service_id>.mnc<MNC>.mcc<MCC>.3gppnetwork.org

(see notes 1 and 2)

Domain name that is to be resolvable by network nodes only. This format inherently adds protection to the identified node, in that attempted DNS resolutions instigated directly from end user equipment will fail indefinitely.

<service_id>.mnc<MNC>.mcc<MCC>.pub.3gppnetwork.org

(see notes 1 and 2)

Domain name that is to be resolvable by UEs and/or network nodes. This format inherently adds global resolution capability, but at the expense of confidentiality of network topology.

<service_id>.mnc<MNC>.mcc<MCC>.ipxuni.3gppnetwork.org

(see notes 1 and 2)

Domain name for UNI interface that is to be resolvable by UEs that are connected to an inter-PLMN IP network that has no connectivity to the Internet.

This format inherently adds resolution capability for UEs in closed IP networks e.g. IPX.

<service_id>.mcc<MCC>.visited-country.pub.3gppnetwork.org

(see notes 1 and 2)

Domain name in the visited country that is to be resolvable by UEs and/or network nodes, which is not specific to an individual operator.

<service_id>.nid<NID>.mnc<MNC>.mcc<MCC>.3gppnetwork.org

(see notes 1 and 3)

Domain name of a Stand-alone non-public network that is to be resolvable by network nodes only. This format inherently adds protection to the identified node, in that attempted DNS resolutions instigated directly from end user equipment will fail indefinitely.

Table E.1: Sub‑domain formats for the "3gppnetwork.org" domain and their respective intended usage

NOTE 1: "<service_ID>" is a chosen label, conformant to DNS naming conventions (usually IETF RFC 1035 [19] and IETF RFC 1123 [20]) that clearly and succinctly describe the service and/or operation that is intended to use this sub‑domain.

NOTE 2: "<MNC>" and "<MCC>" are the MNC (padded to the left with a zero, if only a 2‑digit MNC) and MCC of a PLMN.

NOTE 3: "NID", "<MNC>" and "<MCC>" are the NID (hexadecimal digits as specified in clause 12.7), MNC (padded to the left with a zero, if only a 2‑digit MNC) and MCC identifying a Stand-alone Non-Public Network (SNPN).

Care should be taken when choosing which format a domain name should use. Once a format has been chosen, the responsible working group shall then check the CR and either endorse it or reject it. If the CR is endorsed, then the responsible working group shall send an LS to the GSMA NG with TSG-CT in copy. The LS shall describe the following key points:

– the context

– the service

– intended use

– involved actors

– proposed new sub‑domain name

GSMA NG will then verify the consistence of the proposal and its usage within the domain’s structure and interworking rules (e.g. access to the GRX/IPX Root DNS servers). GSMA NG will then endorse or reject the proposal and inform the responsible working group (in 3GPP) and also TSG CT. It is possible that GSMA NG will also specify, changes to the newly proposed sub‑domain name (e.g. due to requested sub‑domain name already allocated).

NOTE 4: There is no need to request GSMA NG for new labels to the left of an already GSMA NG approved "<service_ID>". It is the responsibility of the responsible working group to ensure uniqueness of such new labels.

It should be noted that services already defined to use the ".gprs" domain name will continue to do so and shall not use the new domain name of ".3gppnetwork.org"; this is to avoid destabilising services that are already live.
