What is P-Access-Network-Info?
The P-Access-Network-Info header is a 3GPP-specific header and indicates to the IMS network over which access technology the UE is attached to IMS. In our example the access technology is GPRS. It also includes the Cell Global ID (CGI), which indicates the location of the user.
What is P header in SIP?
P-headers. The Private Header Extensions to SIP, also known as P-Headers, are special header fields whose applicability is limited to private networks with a certain topology and characteristics of lower layers’ protocols. P-Visited-Network-ID: Identification string of the visited network.
What is Pani IMS?
A User Equipment transmits to a Call Session Control Function (CSCF), a message containing a P-Access-Network-Info (PANI) header. The stored information can be used to control access to the IMS network based on the access network being utilized or the user location.
What are the private headers in IMS?
As part of its RFC 3455 support, the Oracle Communications Unified Session Manager supports the following headers in its IMS implementation:
- P-Associated-URI.
- P-Asserted-Identity.
- P-Called-Party-ID.
- P-Visited-Network-ID.
What is IMS architecture?
IP Multimedia Subsystem or IMS is a standards-based architectural framework for delivering multimedia communications services such as voice, video and text messaging over IP networks.
What is the P-charging-vector?
The SBC Core supports P-Charging-Vector (PCV) headers as part of P-CSCF functionality.
What is P-asserted-identity?
P-Asserted-Identity and Privacy Headers The P-Asserted-Identity contains the caller id information for the call on the INVITE SIP packet. The Privacy header contains information on which parts of the caller id are private. This is the acceptable way to specify privacy information for calls.
What is SIP call flow?
Basic SIP session setup involves a SIP UA client sending a request to the SIP URL of the called endpoint (UAS), inviting it to a session. If the user takes the call, capabilities are negotiated and the call commences. If the user does not take the call, it can be forwarded to voice mail or another number.
What are SIP methods?
What are SIP methods – requests and responses?
- INVITE = Establishes a session.
- ACK = Confirms an INVITE request.
- BYE = Ends a session.
- CANCEL = Cancels establishing of a session.
- REGISTER = Communicates user location (host name, IP).
What are the three original IMS?
There are three basic forms of IMS hierarchical databases:
- “Full Function” databases.
- “Fast Path” databases.
- High Availability Large Databases (HALDBs)
What is IMS network?
The IP Multimedia Subsystem, IMS for short, refers to the standard for a telecommunication system which controls multimedia services accessing different networks. The IP Multimedia Subsystem is based on the All-IP network. IMS systems are primarily used in mobile networks but also in fixed-line networks.
What is Pani header?
The PANI header is a 3GPP-defined header and indicates to the IMS network over which access technology the UE is attached to the IMS, and also the location of the user.
What is the P-access-network-Info header?
The P-Access-Network-Info header is a 3GPP-specific header and indicates to the IMS network over which access technology the UE is attached to IMS. In our example the access technology is GPRS. It also includes the Cell Global ID (CGI), which indicates the location of the user.
What is the P-access-network-Info header field in rfc7315?
Introduction [ RFC7315] defines the Session Initiation Protocol (SIP) [ RFC3261 ] P-Access-Network-Info header field. The header field syntax contains an ‘access-info’ header field parameter, with a set of pre-defined values. Most pre-defined values follow the ‘generic-param’ rule [ RFC3261 ].
What is the P-associated-URI header field?
Applicability Statement for the P-Associated-URI Header Field The P-Associated-URI header field is applicable in SIP networks where the SIP provider allows a set of identities that a user can claim (in header fields like the From header field) in requests that the UA generates.
What is the purpose of the access-type field?
The access-type field is followed by the access-info field which identifies the mobile phone cell that provides network access. The location of this cell provides the means to geographically locate connected mobile handsets. utran-cell-id-3gpp — when the RAT- Type AVP value is 1000
