Abstract

A wireless communication network and a mobile device (400) may support Circuit Switched CS and Packet Switched PS services. Some types of communication services (e.g. voice, text, data, etc.) may be supported using a CS service or using a PS service. In some embodiments, the PS service is an IMS service using Session Initiation Protocol SIP to provide a "CS-like" communication service such as voice or text message. According to the disclosure, a mobile device may detect that it is process data for the PS service (3-1). For example, a SIP component that supports the PS service may become inoperable. In response, the mobile device attempts to support the communication service using the CS service (3-2).
