Problems solved by technology

[0020] Also, without knowing the type of reference point for the reserved IP terminations, the MGW cannot provide proper statistics
[0021] Therefore, if no separation of IP interfaces is available, all services must be supported in the same way in all interfaces, which causes a large resource reservation in the MGW
Additionally, this introduces unnecessary complexity to the MGW

Abstract

A control apparatus determines a user plane interface type via which a call is to be processed, indicates the user plane interface type in a termination reservation message and transmits the termination reservation message. A gateway apparatus receives the termination reservation message, determines the user plane interface type from the termination reservation message and performs processing in accordance with the user plane interface type.

Description

technical field [0001] The invention relates to a communication network system with different IP interfaces. In particular, the invention relates to packet-switched core networks used to interconnect different access networks. Background technique [0002] In mobile networks, for example, according to figure 1 In the shown 3GPP Re14 (3rd Generation Partnership Project Release 4) architecture network, different access networks are interconnected using a core network such as a MSC (Mobile Switching Center) server system. [0003] In Re14 networks, the MSC functionality is split into two logical functions, which are usually provided by physically independent network elements, namely the Media Gateway (MGW) and the MSC Server. The MSC control function is provided by the MSC server. The MGW provides the bearer switching function of the MSC. [0004] like figure 1 As shown, the MGW provides different user plane interfaces A, Iu, Nb and Mb, which are based on TDM (Time Divisio...
