Definitions

  • the present invention relates to an arrangement for improving the architecture of communication systems supporting mobility.
  • the present invention relates to a functional separation architecture supporting mobility.
  • the present invention has been developed in connection with improving the architecture of a mobile communication system.
  • the present invention has been devel- oped in order to introduce mobility, i.e. the capability to deliver telecommunication services to the user anywhere and at any time, to a communication system in a well -structured way.
  • the present invention demonstrates that the mobility functions can be realised as a functional separated layer .
  • this invention proposes a function sepa- ration architecture for communication systems that supports mobility. STATE OF THE ART
  • TINA Telecommunication Information Networking Architecture
  • TIN95i Telecommunication Information Networking Architecture
  • the existing communication system architectures do not consider mobility as separate layer but either allocate the mobility functions in the Network resource layer or the application/service layer. There are several consequences for the first case where the mobility functions are integrated on the network resource layer such as in
  • GSM Global Mobile System
  • UPT Universal Personal Telecommunication
  • the object of the present invention is to propose a functional separation architecture for the telecommunication system in question, whereby mobility is supported in a far more efficient and economic manner.
  • Another object of the present invention is to dedicate a functional layer to mobility functions and mechanisms.
  • Still another object of the present invention is to introduce such mobility support in any open distributed processing (ODP) system or similar.
  • ODP open distributed processing
  • Such an architecture may comprise a separate functional layer for mobility, called mobility layer, in addition to the network resource layer, the DPE layer and the application layer.
  • such an architecture may comprise three domains, i.e. the user domain, the terminal domain and the telecom system domain.
  • Fig. 1 is a block diagram illustrating the functional separation architecture supporting mobility, as defined in accordance with an embodiment of the present invention.
  • Fig. 1 illustrates in a schematical manner a first e - bodiment of a functional separation architecture according to the present invention, which functional separation architecture comprises appropriate mobility layers supporting and facilitating the mobility of the associated communications system.
  • the whole communication system consisting of users, terminals and telecommunications system is represented by a model consisting of three domains: user domain, terminal domain and telecom system domain.
  • Network resource layer In the telecom system domain, we have defined five func- tional layers: Network resource layer, DPE (Distributed Processing Environment) layer, Mobility layer, Security layer and Application layer.
  • DPE Distributed Processing Environment
  • the network resource layer comprises the objects con- trolling/managing the transport network which is used in the establishment and release of stream flows.
  • the DPE layer comprises objects of the distributed computing infrastructure which implement the distribution transparencies.
  • the DPE layer provides various DPE services to the applications.
  • the mobility layer comprises the objects which enable the support of mobility.
  • the security layer comprises objects which are dealing with security issues.
  • the application layer comprises the objects which make use of the functions offered by other layers to provide services to users .
  • the objects in the different layers communicate internally in the layer as well as with objects in the other layers.
  • the distinction between the application layer and the network resource layer reflects the call and connection separation principle introduced by the IN (Intelligent Network) architecture.
  • Objects in the network resource layer use services from the DPE layer. Recipro- cally, the DPE layer can optionally use the network resource layer to establish a bearer for the kernel transport network (kTN) .
  • the mobility layer uses services from the DPE layer, the network resource layer and the secu- rity layer.
  • the security layer uses services from the DPE layer and the network resource layer.
  • the application layer may use all other layers to realise its functions .
  • TINA-C defines only three layers: network resource layer, DPE layer and service layer [TIN95e] .
  • the architecture presented here can be considered as an enhancement of the TINA architecture .
  • the terminal domain there are four functional layers corresponding to the ones in the telecom system domain: network resource layer, DPE layer, mobility layer and security layer.
  • network resource layer corresponding to the ones in the telecom system domain
  • DPE layer corresponding to the ones in the telecom system domain
  • mobility layer corresponding to the ones in the telecom system domain
  • security layer corresponding to the ones in the telecom system domain. The reason that there is no application layer in the terminal domain is because we choose to as- sociate the usage of a terminal with a user.
  • the security layer comprises objects which assist the user in the security procedures such as authentication.
  • the user domain in order to communicate with the telecom system domain, the user domain always requires a terminal domain.
  • the domain partitioning here is an administrative one which does not correspond to a technological one.
  • Technologically the two domains may be unified onto one domain.
  • the analysis is independent of whether or not these domains are separate technology domains.
  • Application objects of the user do- main are running on the terminal domain.
  • the relationship between the user domain layers and the terminal domain layers is therefore similar to the relationship between layers of the same domain.
  • Objects in the application layer of the user domain may use all the layers of the terminal domain.
  • the relationship between the user domain layers and the telecom system domain layers and the relationship between the terminal domain layers and the telecom system domain layers are of peer-to-peer type, e.g. terminal domain network resource layer may communicate telecom system domain network resource layer, etc.
  • the proposed Functional Separation Architecture yields a high level of modular: ty and flexibility.
  • the layers are autonomous and can be designed and implemented separately. Any internal changes in one layer does not affect the other layers as long as its interfaces remain unchanged.
  • TINA-C Domain types and basic Reference Points in TINA, May 1995.
