Embodiment Construction

[0013] exist figure 1 In , a portion of a communication network is shown, including a communication link 10 . Generally, this communication link 10 may exist between applications, as will be described below. In particular, the communication link 10 may exist between a user and a network domain (i.e., user access), or within a network domain (i.e., intra-domain communication), or between two different domains (i.e., , inter-domain communication). For example, the communication link 10 may be part of a VoIP (VoIP is Voice over IP) application and connects eg an IP phone (IP is Internet Protocol) to another user via the Internet.

[0014] As an example, now assume that the communication link 10 exists between the user application and the network domain application, ie the case of user access. However, it should be emphasized that the following description also applies in conjunction with said other scenarios (ie, intra-domain communication and inter-domain communication). In ...

Abstract

A method of forwarding signaling information within a communication network is described. The signaling information is based on a signaling protocol (e.g SIP). A message is generated by encapsulating the signaling information (e.g. I') according to given definitions (e.g. D). Furthermore, non-signaling information (e.g. R) is added to the message.

Description

technical field [0001] The invention relates to a method for forwarding signaling information in a communication network. The invention also relates to a corresponding communication network. Background technique [0002] In a communication network, signaling information is required in order to establish a connection between two users. The signaling information is generated according to a signaling protocol. For example, to establish a communication link between a so-called IP (IP stands for Internet Protocol) telephone and the Internet, SIP (SIP stands for Session Initiation Protocol) or SDP (SDP stands for Session Description Protocol) or other signaling protocols can be used. Such communication via the Internet is commonly referred to as VoIP (VoIP stands for Voice over IP). [0003] In these applications, it is usually necessary to add rules or other extensions to the signaling information. For example, providers of network domains often want to add dedicated rules or...
