9、ntrol entity (NACE) and the network information distribution physical entity (NID-PE) of the mobility management control entity (MMCE). The M13 interface provides the keying material, derived from the user equipment (UE) authentication procedure, in support of the security association required betwe

11、he International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying techn
12、ical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which,
13、in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC
14、. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ens
15、ure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words doe
16、s not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concernin
17、g the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patent

This information is stored in the transport location management physical entity (TLM-P
39、E) and is pushed to the network information distribution physical entity (NID-PE) in the mobility management control entity (MMCE). 6.2 M13 reference model This clause describes the M13 reference architecture.

ITU-T Q.3230 (08/2012) 6.3 Physical entities and capabilities 6.3.1 TLM-PE The TLM-PE responds to location queries from service
41、 control functions and applications. The actual information delivered by the TLM-PE may take various forms (e.g., network location, geographical coordinates, postal address, etc.) depending on the agreement with the requester and on user preferences regarding the privacy of its location. The TLM-PE
42、may play several roles, i.e., the home role, the local role, or both. In its home role the TLM-PE stores a pointer to the TLM-PE instance that is playing the local role for the attachment. The current location information of the user/CPE in the access domain is stored and bound in the local TLM-PE.
43、Thus, when the user/CPE moves in the same access domain, only the location binding information of the local TLM-PE needs to be updated; the location binding information of the home TLM-PE does not need to be updated. The local TLM-PE is in the access network to which the terminal equipment is attach
44、ed. The home TLM-PE is in the network designated by the TUP-PE. Where these networks differ, communication between the local and home TLM-PE instances takes place over the Ng reference point. Namely, the home TLM-PE may provide the SCE with user network profile information through the local TLM-PE o
45、f the visited network in order to support mobility when the user is nomadic. Similarly, the home TLM-PE is able to provide the SCE with user network profile information through the local TLM-PE of another service provider for roaming on such an access network. The functionality of the TLM-PE is furt
46、her detailed in clause 7.2.3 of ITU-T Y.2014. 6.3.2 NID-PE The NID-PE communicates with the entity making the handover decision during the network discovery phase. The handover decision may be made by either the UE or the handover decision and control physical entity (HDC-PE). The NID-PE has the fol
47、lowing responsibilities: Distributing handover policy, which is a set of operator-defined rules and preferences that affect the handover decisions taken by the UE or HDC-PE. For example, a handover policy can indicate that vertical handover from E-UTRAN access to WLAN access is not allowed. It can a
48、lso indicate, e.g., that WiMAX access is preferable to WLAN access. Distributing other information provided by the NIR-PE. The functionality of the NID-PE is further detailed in clause 6.4 of ITU-T Y.2018. 7 Signalling requirements The M13 reference point allows the TLM-PE to interact with the NID-P
49、E for pushing mobility service parameters such as keying material, in support of the security association required between the NID-PE and the UE. The M13 reference point is an intra-domain reference point. The M13 reference point allows information exchange as follows: The mobility service parameters information is pushed by the TLM-PE to the NID-PE (see Figure 7-1).
