Communication network elements and communication methods therebetween

摘要

In a communications network an arrangement for transmitting data between a network element of a first type (e.g. BSS) and a network element of a second type (e.g. MSC) is disclosed. A relationship initialisation message is transmitted from the first network element to the second network element, the message including an information element (e.g. BSC-SCL IE) defining one or more communication modes (e.g. CODECs) with which the first network element is configured to communicate.
