Foreword This Technical Report (TR) has been produced by ECMA International in close collaboration with ETSI Technical Committee Telecommunications and

19、 Internet converged Services and Protocols for Advanced Networking (TISPAN) in the context of a Common Work Item. Introduction The present document identifies key mobility issues for IP-based enterprise communications. It defines terms for different types of mobility, describes basic functionality i

20、n support of mobility, and lists common deployment scenarios. For each scenario the report identifies functional requirements and standardization gaps related to the management of mobility, identity, terminals and reachability. The present document is based upon the practical experience of ECMA memb

21、er companies and the results of their active and continuous participation in the work of ISO/IEC JTC1, ITU-T, ETSI, IETF and other international and national standardization bodies. It represents a pragmatic and widely based consensus. Compared to the 1stEdition, the present document has been comple

22、tely rewritten, taking into account more recent information and identifying requirements and standardization gaps. ETSI ETSI TR 102 477 V2.1.1 (2012-06) 61 Scope Mobility for enterprise communications is the ability for persons and objects, e.g. vehicles, sensors and other machines, belonging to the

23、 enterprise to use communication and information services regardless of changes in their physical location. This includes also the ability to be reached by other persons or objects for communications. The present document encompasses the mobility of enterprise users connecting to enterprise and publ

24、ic IP networks using wired and wireless terminals for voice, data and converged services. It defines terms for different types of mobility, describes basic functionality in support of mobility, and lists common deployment scenarios. For each scenario the report identifies functional requirements and

25、 standardization gaps with the main focus on the management of mobility, identity, terminals and reachability. However, it does not provide technical solutions but lays the foundations for triggering standardization projects in areas where gaps have been identified. More general aspects of enterpris

26、e communications based on Next Generation Corporate Networks (NGCN) and interconnection with Next Generation Networks (NGN) are covered by the companion series of ECMA Technical Reports on NGCN i.1, i.2, i.3 and i.4. 2 References References are either specific (identified by date of publication and/
