Introduction In the last couple of years an increasing number of heterogeneous network types have come to the focus of attention, e.g. heterogeneous access systems (otherwise known as multi-a
35、ccess), Personal Area Networks (PANs), Personal Networks (PNs),moving networks etc. This trend is expected to continue. Different scenarios have been studied in the All-IP Network (AIPN) Feasibility Study in TR 22.978 5, which lists “network extensibility/composition “ as a key aspect of AIPN. The i
36、ntegration of PANs and Personal Networks will be specified within the scope of the Personal Network Management (PNM) work item. Related Technical Specification work is ongoing within the AIPN Stage 1 in TS 22.258 6 and Personal Network Management Stage 1 in TS 22.259 7. It would be desirable for 3GP
37、P networks to be able to integrate many of these heterogeneous network types, or to interwork with them, in an efficient manner that for operators is easy to manage and control. This Technical Report is the result of a feasibility study on Network Composition, the concept of heterogeneous network/sy
38、stem integration and interworking. It builds on the work of AIPN and studies Network Composition in more detail. This includes integration of networks with different administrative domains, and the dynamic and flexible integration of ad-hoc networks, PANs, WLANs etc. Particularly, the possibility fo
39、r a uniform Network Composition procedure is explored, independent of what kind of network is “composed“ with the 3GPP system.

42、abbreviations 3.1 Definitions For the purposes of the present document, the terms and definitions given in 4 and the following apply. Editors note: need to add definition of Compensation Composition Agreement (CA): A Composition Agreement is an electronic agreement between CCNs. It includes the poli
43、cies to be followed by the composed CCNs, the identifier of the composed CCNs, how logical and physical resources are controlled and/or shared between the composing CCNs, compensation information, etc. Where the CA includes commercial and legal factors, the CA should be digitally signed by both CCNs
44、 (to support non-repudiation and legal enforcement). Composition Capable Network (CCN): A network or user device capable of Network Composition. A network may be a 3GPP network or non-3GPP network. Composition Process: A set of phases that all together describes the necessary procedures to perform a
45、 Network Composition between CCNs. The phases may not need to be strictly ordered, and one or more of the phases can be omitted depending on how the Network Composition is applied and its purpose. Decomposition Process: A set of phases that all together describes the necessary procedures to cancel a
46、 Network Composition between CCNs. The phases may not need to be strictly ordered, and one or more of the phases can be omitted depending on how the Network Composition is cancelled. Network Composition: A dynamically created cooperation between an evolved 3GPP network and another network or user de
47、vice, or between networks/user devices in general. This cooperation is ruled by the Composition Agreement agreed during the Composition Process. Resource, resource control, resource usage, and resource access provisioning: A resource is an entity provided by a CCN, e.g. bandwidth, AAA (Authenticatio
48、n, Authorisation, and Accounting) functionality and mobility functionality. It is characterized by the following: A resource is controlled in the sense of configured and administered - by a CCN (e.g. a PLMN controls its AAA and mobility functionality) in order to show a certain specified behaviour.
49、A resource can be used by a CCN (e.g. a User Equipment (UE) or PAN using the AAA and mobility functionality provided by a PLMN). The access to usage of the resource is provided (e.g. a Visited PLMN (VPLMN) provides access to the AAA functionality in the Home PLMN (HPLMN), or a mobile network provides access to the mobility functionality of a PLMN). Usage, control and access provisioning to a given resource can be performed by different CCNs. A resource may have inherent, resource type-specific properties that may be subject to CA negotiation.
