name: ICS
full_form: Implementation Conformance Statement
context: Services - Support for SMS and location services typically provided by the MSC The ICS IWF provides support for inbound and outbound roamers in networks that do not support IMS or ICS such that the other network does not need any support for IMS or ICS (including no support for SeDoC). For an outbound roamer (i.e. a SeDoC subscriber), the ICS IWF maps the procedures between the VPLMN and the HLR into IMS procedures. For an Inbound roamer, the ICS IWF maps the procedures between the HPLMN and the MSC into IMS procedures. The ICS IWF may be used independently from SeDoC to enhance ICS roaming scenarios. The MSC Server Enhanced for SeDoC uses the IMS domain for authentication and subscription management interacting with the HSS, a new procedure is introduced to authenticate the subscriber and obtain the CS encryption keys. In the roaming case, the ICS IWF function maps the parameters between IMS authentication and MSC/HLR authentication procedures, presenting only the MSC/HLR procedure
description: The Implementation Conformance Statement (ICS) Interworking Function (IWF) enables interoperability between IP Multimedia Subsystem (IMS) and Circuit Switched (CS) networks. It maps procedures and parameters between these domains to facilitate seamless communication and roaming capabilities.
explanation: The text describes the ICS IWF as a component that facilitates communication and interoperability between different network domains, which is a key characteristic of a Network Function.
