full_form: Interworking Function
context: Table 11.8-1: New Message Bitmap IE Coding of New Message Bitmap. Table 11.8-2: Coding of New Message Bitmap IE CTCH BS Index i: Each bit of the New CBS Message Bitmap refers to the content of CTCH BS index i, i=B,...,E. Its meaning is as follows: 1 The CTCH BS index i contains a BMC Message partly or completely which was either not sent during the previous schedule period, or sent unscheduled during the preceding schedule period; or, the CTCH BS is indicated as of free usage, reading advised; or it contains the Schedule Message partly or complete of the following CBS schedule period, or it contains a CBS41 Message partly or complete. The value is 1 both for the first transmission of a given BMC message in the CBS schedule period or a repetition of it within the CBS schedule period. 0 The CTCH BS is such that value 1 is not suitable. The length of the New Message Bitmap is given by the IE Length of CBS Schedule Period. If it is not a multiple of 8 the remaining bit positions are padded
description: The Interworking Function (IWF) enables communication between different network technologies like ATM and IP. It establishes connections and exchanges signaling information between disparate networks, ensuring seamless interoperability. In 3GPP TS 25.933, the IWF facilitates communication between an AAL2/ATM SRNC and an IP DRNC.
explanation: The IWF is a Network Function because it acts as an intermediary, enabling different network technologies to communicate. It performs crucial tasks like connection establishment and signaling exchange, directly contributing to network interoperability.
