name: HOW
full_form: HandOver Word
context: (text extracted are shown in Italics): In case of RRC connection release with cause "Directed Signalling connection re-establishment" or in case of an error, the PMM state of the MS and the 3G-SGSN may lose synchronisation. In this case the MS may be in the PMM-IDLE state while the 3G-SGSN is in the PMM-CONNECTED state. Observation 1: From the NAS point of view, it can be noted that RRC Connection Release with cause "Directed Signalling connection re-establishment" is treated like an error condition where the UE and SGSN are in two different PMM states. If the SGSN in PMM-CONNECTED state receives Iu connection establishment request from the MS, the SGSN shall ensure the new Iu connection and the existing one are for the same MS, and if so the SGSN shall process the new request and release existing Iu connection and all RABs associated with it. To ensure that the new Iu connection and the existing one are for the same MS, the SGSN may perform the security functions. Observation 2:
description: The HandOver Word (HOW) is a procedure related to the coding of control frames in the Iu UP protocol, specifically within the context of initialisation, rate control, time alignment, and error event procedures. It outlines how these control frames are formatted and used for communication between network elements.
explanation: The classification as a Procedure is based on the context provided, which describes specific steps and formats (e.g., Figure 24, Figure 25) for coding control frames in various scenarios such as initialisation, rate control, time alignment, and error events. This indicates that HOW refers to a set of operations or steps taken within the Iu UP protocol.
