Definitions

  • EPS Evolved Packet System
  • a User Equipment UE has access to a an EPS network providing communication services (including providing IP connectivity).
  • the EPS network comprises a Core Network called EPC (Evolved Packet Core) that can be accessed not only by 3GPP access, but also by non-3GPP access.
  • EPC Evolved Packet Core
  • WLAN access A typical example of non-3GPP access, which will be considered more particularly in the following, is WLAN access.
  • WLAN access to EPC is specified in particular in 3GPP TS 23.402 and 3GPP TS 24.302.
  • an IPsec tunnel is established between the UE and an evolved Packet Data Gateway ePDG, to ensure that the UE and the network can communicate in a secure way.
  • the procedure for selection of an ePDG by the UE is specified in particular in 3GPP TS 23.402 and 3GPP TS 24.302.
  • Embodiments of the present invention in particular address such needs.
  • the present invention generally relates to mobile communication networks and systems.

  • a method for the determination of the local emergency numbers in a country a User Equipment UE is located comprising at least one step performed by at least one of a thus configured P-CSCF or DNS server.
  • FIG. 1 is intended to illustrate, in a simplified way, an example of information used for ePDG selection according to first embodiments of the invention
  • FIG. 2 is intended to illustrate, in a simplified way, an example of information used for ePDG selection according to second embodiments of the invention
  • FIG. 3 is intended to illustrate, in a simplified way, an example of information used for ePDG selection according to third embodiments of the invention.
  • FIG. 4 is intended to illustrate, in a simplified way, an example of a method for ePDG selection according to examples embodiments of the invention disclosed herein.
  • a WLAN capable UE When a WLAN capable UE is attached via 3GPP access to a 3GPP RPLMN (HPLMN or VPLMN), it is specified according to TS 23.402 clause 4.5.4 (see version v13.4.0) that the UE selects an ePDG in that RPLMN or in its HPLMN.
  • the UE When the UE is not attached via 3GPP access to a 3GPP PLMN, it is specified that the UE shall select an ePDG in the country it is located in by constructing a corresponding Operator Identifier FQDN (with MCC and MNC as specified in TS 23.003). But a condition is that the selected PLMN shall be in the “ePDG selection information” (see 4.5.4.4 bullet 2)a)), which does not include all the PLMNs that have roaming agreements for untrusted WLAN with the UE's HPLMN but only the mandatory and preferred PLMNs (i.e. the local PLMNs for which the HPLMN has decided it is mandatory or preferred that the UE selects an ePDG in that PLMN). That “ePDG selection information” has been previously provided to the UE by its HPLMN.
  • Another use case when the UE must select an ePDG in the same country it is located in is for emergency calls via WiFi when the UE is not attached to any 3GPP PLMN.
  • the UE is assumed to be able to determine the country it is located in.
  • the idea is to enable a WLAN capable UE to get via new additional information in the ePDG selection information and/or via one or more DNS queries, a list of “local” PLMN's (i.e. PLMN's that are in the country the UE is located in) which have roaming agreements for untrusted WLAN access with the UE's HPLMN i.e. that own one or more ePDGs that can authenticate and authorize UE(s) from the HPLMN of the UE.
  • the DNS servers are public (accessible from anywhere on the Internet).
  • the UE can attempt to establish an IPSec tunnel per TS 24.302 subclause 7.2.2 to an ePDG that is operated by one of these PLMN's.
  • Alternative 1 Three alternatives, referred to as Alternative 1, Alternative 2, Alternative 3, may be distinguished.
  • One alternative is to extend the attributes of each PLMN in the ePDG selection info “mandatory, preferred” with “not preferred”. This allows knowing which PLMNs have roaming agreements with the UE's HPLMN.
  • the UE already knows the list of MCCs of the country it is located in, or it needs to query a public DNS to get the full list of PLMNs (MCC and MNC) of the country.
  • the corresponding DNS records are managed by a central administration.
  • the input is a FQDN which includes the MCC (or one of the MCCs) of the country the UE is located in.
  • the output is the list of the identities of the PLMN's of the country (MCC and MNC).
  • the Resource Record is a NAPTR record.
  • the UE attempts to establish an IPSec tunnel per TS 24.302 subclause 7to an ePDG that is operated by any PLMN in the above list only if the PLMN is configured in the ePDG selection Info.
  • the ePDG selection info is not enhanced with “not preferred”. In this case, the UE does not know all the roaming agreements since the ePDG selection info does not contain the “non-preferred PLMNs”.
  • the UE first queries a public DNS to get the list of local PLMNs (MCC and MNC) of the country exactly as in alternative 1 but even if it knows all the MCCs of the country.
  • This second set of queries corresponds to DNS queries targeting a FQDN which includes:
  • Another alternative is for the UE to directly query a DNS that returns the list of PLMNs which have a roaming agreement for untrusted WLAN with the UE's HPLMN.
  • the input of the DNS is a FQDN which includes:
  • the output of the DNS is a list of the identities (MCC and MNC) of the PLMNs of the country that have roaming agreements for untrusted WLAN access with the UE's HPLMN. That list can be ordered.
  • This feature is e.g. to be used
  • a WLAN capable UE can determine the country it is located in and either the UE is attempting to make an emergency call via WiFi or the UE has received instructions that in the country where it is currently camping it shall only use ePDG that are located in the country, and if the UE is not attached via 3GPP access to a 3GPP PLMN (or if the UE has failed to be served by an ePDG of the RPLMN that serves it over 3GPP access), the UE selects an ePDG in a PLMN in this country as follows:
  • 3GPP TS 23.003 provides an informative annex D “Applicability and use of the “0.3gppnetwork.org” domain name” that can be used to construct a FQDN.
  • a rule of this annex is that a DNS managed by an operator identified by mnc ⁇ MNC>.mcc ⁇ MCC> can be reached by an UE by using a FQDN with the form “ ⁇ service_id>.mnc ⁇ MNC>.mcc ⁇ MCC>.pub.3gppnetwork.org”.
  • a public DNS that is not managed by a specific operator should use another form.
  • the input FQDN to be used for the DNS query would have the form “mcc ⁇ MCC>.local-plmn.pub.3gppnetwork.org”, the public DNS server returning a list of “mnc ⁇ MNC>.mcc ⁇ MCC>.local-plmn.pub.3gppnetwork.org” output FQDNs.
  • the MCC value in an output FQDN could have a different value than the MCC value in the input FQDN.
  • FIG. 1 An example of information used for ePDG selection by a UE, in embodiments related to the first alternative, is illustrated in FIG. 1 .
  • such information includes ePDG selection information enhanced with non-preferred PLMNs, and may (as illustrated with dotted lines) include a list of local PLMNs, obtained e.g. by DNS query to a public DNS server.
  • FIG. 2 An example of information used for ePDG selection by a UE, in embodiments related to the second alternative, is illustrated in FIG. 2 .
  • such information includes a list of local PLMNs obtained e.g. by DNS query to a public DNS server, and information noted local PLMN roaming agreement information (indicating if a local PLMN has roaming agreement with the UE's HPLMN for untrusted WLAN access to EPC) obtained e.g. by DNS query to a local PLMN DNS server.
  • the UE selects an ePDG in a PLMN in the country it is located in as follows:
  • TS 23.003 provides an informative annex D “Applicability and use of the “0.3gppnetwork.org” domain name” that can be used to construct a FQDN.
  • the FQDN would have the form “hmnc ⁇ MNC>.hmcc ⁇ MCC>.mcc ⁇ MCC>.lcepdg.pub.3gppnetwork.org”, where the service is local country ePDG (lcepdg), the MCC of the country the UE is located in is mcc, and the UE's HPLMN is hmcc plus hmnc.
  • the DNS is configured with a list of local PLMN in the country identified by “mcc” the UE's HPLMN has WLAN roaming agreements with. Until successful IPSec tunnel establishment with an ePDG, for each of the local PLMN in the list:
  • the UE fetches the NAPTR record associated with “hmnc ⁇ MNC>.hmcc ⁇ MCC>.mcc ⁇ MCC>.lcepdg.pub.3gppnetwork.org.”
  • the DNS NAPTR information it gets is a set of NAPTR records:
  • the DNS resolver in the UE then needs to pick an Operator Identifier FQDN and issues a DNS lookup towards that new domain in order to find an ePDG of the corresponding local PLMN.
  • FIG. 3 An example of information used for ePDG selection by a UE, in embodiments related to the third alternative, is illustrated in FIG. 3 .
  • such information includes a list of local PLMNs having roaming agreement with the UE's HPLMN for untrusted WLAN access to EPC (noted list of PLMNs having roaming agreement), obtained e.g. by DNS query to a DNS server.
  • a fair usage of the PLMN (s) in the list can be achieved by the DNS providing the list of local PLMNs using NAPTR records having the same order and same preference (per RFC 34.03 definitions), and the DNS resolver in the UE randomly choosing between the PLMNs for which an IPSec tunnel establishment has not been successfully attempted.
  • the DNS provides a list of local PLMNs in a random or round robin order and that the UE always start with the first PLMN in the list.
  • P-CSCF Packet Control Function
  • HPLMN Home PLMN
  • VPLMN Visited PLMN
  • the P-CSCF in the HPLMN needs to determine whether session signaling initiated by the UE in the VPLMN targets an emergency number defined in that VPLMN (for example the emergency numbers related with child or women abuse may vary from country to country).
  • the P-CSCF in HPLMN has to redirect the UE towards selecting a P-CSCF for emergency services in the VPLMN.
  • the P-CSCF could be locally configured with the list of emergency numbers associated with each country of a VPLMN with which it has roaming agreements.
  • the P-CSCF takes the MCC of the VPLMN (where the UE is located) to build a specific FQDN associated with the emergency numbers in that country and issues a DNS record request to get the list of the emergency numbers in that country.
  • the P-CSCF tries to get a list of local emergency numbers (i.e. a list of emergency numbers in the country the UE is located in) by performing a DNS query on an input FQDN containing “mcc ⁇ MCC>” (of the PLMN where the UE is camping) to a public NAPTR DNS server that returns a list of such emergency numbers;
  • the domain of the input FQDN does not correspond to an individual operator as the corresponding DNS record is likely not to be managed by an individual operator (could be managed by GSMA like the NAPTR record of the public DNS server that returns a list of FQDN that each contains a “mnc ⁇ MNC>.mcc ⁇ MCC>” of a local PLMN).
  • the P-CSCF is not assumed to retrieve this list each time an UE registers or issues session related signaling as it may cache the DNS record received as part of DNS look-up
