A SIP-based device communication service for OSGi framework

Abstract

This paper outlines an approach toward extending the OSGi (Open Services Gateway Initiative) framework to support interoperability with mobile devices. The approach is based on the use of SIP (Session Initiation Protocol), which is likely to be employed by nextgeneration mobile networks. The extensions to OSGi allow a SIP device to participate in an OSGi platform and allow OSGi services to be exported into a mobile (SIP-based) environment. In this paper, we propose an architecture supporting the integration of SIP with OSGi, provide some application scenarios and describe the details of the SIP Service for OSGi.

On the Design of a SIP-Based Binding Middleware for Next Generation Home Network Services

“…They moreover showed the interest for a design above the OSGi platform in [5]. Although we think that the OSGi platform is the right technology to bring loosely-coupled and well-structured applications to the home, the API shown by their work lacks the essentials of the OSGi Service Oriented Programming.…”

“…Although we think that the OSGi platform is the right technology to bring loosely-coupled and well-structured applications to the home, the API shown by their work lacks the essentials of the OSGi Service Oriented Programming. SIP protocol details are not transparent to the developer and event SIP entities are not programmed as OSGi services (see the static SIPDevice factory in [5]). The dynamicity of SIP services ought to be mirrored by OSGi service dynamicity.…”

“…In some approaches such as [5,4,6], SIP-UPnP bridging is carried out by just inserting UPnP control messages into SIP protocol as text messages using the SIP MESSAGE method. Consequently, the SIP protocol is miss used and the sense that It does not exploit its main strengths related to the mobility and session reconfiguration.…”

“…Only few of them address the problem of mixing SIP interpersonal communication with multimedia home devices [3][4][5][6]. Although the majority of these works follow the SOA (Service Oriented Architectures) paradigm on top of the OSGi platform, the proposed solutions lack of openness and flexibility: these solutions are hardly reusable to develop flexible and useful SIP-based services.…”

State of the Art: Embedded Middleware Platform for A Smart Home

“…Embedded Middleware Platforms SOAP [35], [47], [72], [65] WSDL [21], [85] REST [39], [80], [64] OSGi [40], [53], [83], [81], [29], [54], [68], [49], [69], [38], [76], [46], [14], [77], [19], [11], [13], [60], [82] REST REST is an architecture style for designing networked applications. The idea is that, rather than using complex mechanisms, such as CORBA, RPC or SOAP to connect between machines; simple HTTP is used to make calls between machines [3].…”
