SIP Signalling Resources in 3GPP IP Multimedia Subsystems
نویسندگان
چکیده
The Session Initiation Protocol (SIP) will be used as the signalling protocol in the IP Multimedia (IM) Subsystem of the 3rd Generation Partnership Project (3GPP) UMTS networks. Using the protocol on a large scale to provide equivalent telephony service requires Quality of Service (QoS) observations. This paper discusses SIP signalling resources and their impact on the QoS. The first part summaries observations in conjunction with signalling resources. The second part introduces methodologies that enable the dynamic resource allocation for SIP overlay networks. The third part shows areas where further study is required.

A Simple Model for Calculating SIP Signalling Flows in 3GPP IP Multimedia Subsystems
The 3rd Generation Partnership Project (3GPP) uses the IETF Session Initiation Protocol (SIP) as a signalling protocol in the IP Multimedia Subsystem for 3rd generation UMTS networks. Signalling Messages sent using the SIP protocol pass through intermediate SIP nodes in such a way that the message size grows as a result of additional data being added to the message. Modelling of network flows i...
متن کاملDynamic Resource Allocation in 3GPP SIP Overlay Networks
The Session Initiation Protocol (SIP) is the IETF alternative for session related signalling. SIP will be used in the IP Multimedia Subsystem of 3rd Generation Partnership Project (3GPP) UMTS networks. To be able to guarantee Quality of Service (QoS) to customers in carrier grade networks it is required to ensure QoS for signalling. Resources provided by the multiservices transport network have...

The Session Initiation Protocol (SIP) will be used on a large scale as a session signalling protocol to provide legacy as well as new services. The 3rd Generation Partnership Project (3GPP) has decided to use the SIP protocol in the IP Multimedia Subsystem of future Universal Mobile Telecommunications System (UMTS) networks. If the SIP protocol is used in carrier grade networks, Quality of Serv...

The 3rd Generation Partnership Project (3GPP) will use the Session Initiation Protocol (SIP) as a session signalling protocol in the IP Multimedia Subsystem (IMS) of next generation UMTS systems. Certain nodes on the signalling layer have to process a large number of SIP messages. This paper introduces a concept for efficient SIP message routing and user assignment. The SIP Message Overflow Rou...

The Session Initiation Protocol (SIP) is widely accepted as the IETF alternative the ITU-T H.323 teleconferencing protocol to enable call and media session management and control. It is also used in carrier grade environments, such as the IP Multimedia Subsystem (IMS) of the 3rd Generation Partnership Project (3GPP) in emerging Universal Mobile Telecommunications System (UMTS) networks. This pa...
