A method of handling call establishment requests when a MS moves from one Serving Radio Network Controller (SRNC) to another SRNC in a 3G wireless network, such as a UMTS network. If SRNC Relocation is being prepared, an Iu connection request and Paging request received by the SRNC are suspended and stored in a buffer. If the Relocation procedure completes successfully, the messages are discarded. If the Relocation procedure fails or is cancelled, the messages are processed normally. However, if SRNC Relocation has already been triggered, all call establishment messages (except Direct Transfer Messages) received by the SRNC are ignored. Other post Iu connection messages received by the SRNC are processed instead of potentially being ignored.
