Abstract: Measures for controlling a communication mode setting, such as a power saving procedure in a UE. A UE sends a communication mode preference indication to a communication network control element under consideration of a default prohibit timer. When a response to the communication mode preference indication is received by the UE, it determines whether a change of the behavior for transmitting the power preference information, e.g. a change of a prohibit timer value, is to be executed.

Abstract: A method, apparatus and computer program product are provided to facilitate the combined registration in both the PS domain and the CS domain. In response to an initial request for a combined registration for a PS domain and a CS domain, a method may receive an indication that the registration for one of the domains is successful but that the registration for the other domain is unsuccessful. The method may prevent, in response to the indication that the registration for one domain is successful but that the registration for the other domain is unsuccessful, another request for the combined registration for the PS domain and the CS domain for a predetermined period of time following the initial request. A corresponding apparatus and computer program product are also provided.

Abstract: A network sends downlink a neighbor frequency list for redirection (with at least one neighbor frequency) for measurement, for example event-triggered measurement. For each frequency in the list which a user equipment UE finds to satisfy one or more criteria, for example event-triggering criteria, the idle-state or semi-idle-state UE then takes a measurement of the neighbor frequency and checks whether the measurement satisfies reporting criteria. The UE sends to its serving cell an indication of the neighbor frequency or frequencies whose measurement meets the reporting criteria, without reporting the measurement, such as in a RRC Connection Request message. The serving cell then redirects the UE to establish a connection on a target frequency selected from the indicated neighbor frequencies, and this redirect may be in a RRC Connection Reject message.
