Method and system for transmitting MBMS control information in multicarrier aggregation system

摘要

A method and system for transmitting Multimedia Broadcast Multicast Service (MBMS) control information in a multicarrier aggregation system are disclosed in embodiments of the disclosure. The method includes that: when an MBMS needs to be sent, a network side determines an MBMS-including Component Carrier (CC) and a non-MBMS-including CC, and sends service control information and service data of the MBMS in the MBMS-including CC. The method further includes that: the network side sends, in the non-MBMS-including CC, related control information of the MBMS in the MBMS-including CC. With technical solutions provided by the embodiments of the disclosure, a UE operating or residing in a non-MBMS-including CC can find out timely and accurately the initiation of a session for a UE-interested MBMS in an MBMS-including CC, so as to avoid premature blind gathering of UEs in the MBMS-including CC, thus effectively decreasing duration of impact on uplink random access by the MBMS-including CC.

主权项

1. A method for transmitting Multimedia Broadcast Multicast Service (MBMS) control information in a multicarrier aggregation system, comprising: when an MBMS is sent, determining, by a network side, an MBMS-including Component Carrier (CC) and a non-MBMS-including CC, and sending service control information and service data of the MBMS in the MBMS-including CC; wherein the method further comprising:
sending, by the network side, in the non-MBMS-including CC, related control information of the MBMS in the MBMS-including CC, wherein the related control information is used for indicating whether an MBMS a User Equipment (UE) is interested in starts to be sent; and the method further comprising: when the service control information and the service data are sent, adding, by the network side, an identifier in the MBMS-including CC to indicate that the service control information and the service data are transmitted on the MBMS-including CC.
