Problems solved by technology

[0007] However, when dispersion occurs, this dispersion will be applied to all UEs immediately when the MBMS session on the PL is stopped, so that this dispersion process may cause further problems
Network signaling overload may occur due to a large number of UEs simultaneously selecting alternative frequencies and switching to them

Embodiment Construction

[0017] Embodiments of the present invention will now be described. When the UE conducts the second service after the first service is terminated, selection of a radio channel for the second service by the UE or conduct of the second service by the UE is performed after the first service is terminated for a period of time. The time period depends on one or both of the state of the radio station and the characteristics of the second service. Therefore, the decentralization process does not happen to all UEs immediately, but takes a certain period of time depending on the UE's own state transition process. As a result, a delay factor is introduced into the frequency dispersion process, causing the signaling involved in frequency reselection and / or service transfer to be relatively diffused in time, reducing network load, and avoiding unnecessary frequency reselection. For some state transitions, the time period may be zero, resulting in immediate frequency scatter, while for oth...

Abstract

When a radio station terminates a first service on a first radio frequency channel and selects a second radio frequency channel for engaging in a second service, a time delay is inserted after the termination of the first service and before selecting the second radio frequency channel or before engaging in the second service. The time delay is dependent on the state of the radio station and / or a characteristic of the second service.

Description

technical field [0001] The invention relates to a method for operating a radio station. The invention finds particular but not exclusive application in mobile terminals adapted for use in mobile communication systems such as UMTS (Universal Mobile Telecommunications System) or cdma2000. Background technique [0002] Currently, Multimedia Broadcast Multicast Service (MBMS) was introduced in Release 6 of the UMTS specification. This will enable multimedia services to be efficiently delivered to multiple mobile terminals simultaneously. In UMTS, a mobile terminal is called User Equipment or UE. [0003] Currently, a feature of this specification is Frequency Layer Convergence (FLC), in which the network sends an indication of a preferred frequency for a point-to-multipoint MBMS service (also known as a "preferred layer" PL), so that users intending to join a particular service The UE switches to the PL of the service in order to receive the service. Thus, the number of UEs ...
