Methods and devices for enabling reception of a specific service for terminals in idle mode

摘要

The present invention relates to methods and devices for enabling reception of a specific service for terminals idle mode. More particularly, the present invention relates to such methods and devices enabling mobility for terminals in idle mode so as to receive an MBMS service. In case a terminal is interested in the MBMS service, it applies different reselection rule than normal reselection rule i.e., when the terminal is not interested in the MBMS service. For instance, the terminal manipulates the priority indications received from an eNB and considers MBMS layer the highest priority in case the terminal is interested in MBMS service. If the terminal thus manipulates the priority due to the (intended) MBMS reception, the terminal starts an MBMS timer, which is received as a permission parameter from the eNB.

1. A radio network node, comprising:
a transmitter module and a processor module which together are
configured to transmit a priority indication of assigned priority for plural radio frequencies available within a coverage area of the radio network node, andconfigured to indicate a Multimedia Broadcast-Multimedia Multicast Service (MBMS) service indication assigned to at least one of said radio frequencies that identifies said at least one radio frequency as a MBMS radio frequency,said transmitter module is further configured to transmit at least one permission parameter controlling a receiving terminal in terms of initiating action in regard to accessing a specific MBMS, wherein:
said at least one permission parameter comprises a first timing parameter for setting at the receiving terminal a time limit for manipulating the priority indication in order to permit the receiving terminal to initiate action in regard to accessing the specific MBMS;the at least one permission parameter is transmitted to the receiving terminal in dedicated or broadcast signaling; andthe time limit allows the receiving terminal to manipulate the priority indication of the at least one MBMS radio frequency, relative to the priority indications for other of the radio frequencies, only while the time limit is not expired.
