example 1

[0057] Example 1: MBMS single-cell transmission mode, or MBSFN transmission, but there is only one cell in the MBSFN area.

[0058] Rel-8 LTE stipulates that the MCCH of a single cell is carried by the DL-SCH for transmission, and the DL-SCH is mapped to a Physical Downlink Shared Channel (PDSCH, Physical Downlink Shared Channel). Resource configuration in PDSCH can be indicated by PDCCH.

[0059] Put the MCCH on the subframe carrying the unicast service, and carry an M-RNTI used to identify the MCCH content update notification in the PDCCH of the subframe, where the M-RNTI is a specific value predetermined by the eNB and the UE, and the UE The M-RNTI is known, and the MCCH content update itself is carried in the PDSCH of the subframe, wherein the M-RNTI helps the UE obtain the MCCH content update. The eNB repeatedly sends the M-RNTI at each paging moment in the DRX cycle, and the UE decides whether to further read the content update of the MCCH according to the information o...

example 2

[0063] Example 2: MBMS multi-cell transmission mode, or MBSFN situation.

[0064] In the latest work item description of LTE Rel-9, the description about MCCH does not support MBSFN combination, and may not consider the primary and secondary structures. MCCH can be transmitted on DL-SCH or MCH.

[0065] According to the current LTE regulations on MCCH, the MCCH of an MBSFN area needs to be carried on the subframe allocated by the area for carrying the MBMS service in the area. For an MBSFN area, the system will configure the corresponding radio frame carrying MBMS service and some subframes in the radio frame for the area according to the MBMS service-related information in the MBSFN area, such as the number of MBMS services, It is used to send MBMS services in this MBSFN area.

[0066] The system side places the MCCH in the relevant subframe in the MBSFN radio frame configured by the system, such as the first subframe, and carries an M-RNTI used to identify the MCCH content...

example 3

[0071] Example 3: MBMS multi-cell transmission mode, or MBSFN situation.

[0072] In the latest work item description of LTE Rel-9, the description about MCCH does not support MBSFN combination, and does not consider the primary and secondary structures. MCCH is transmitted on MCH.

[0073] According to the current LTE regulations on MCCH, the MCCH of an MBSFN area needs to be carried on the subframe allocated by the area for carrying the MBMS service in the area. For an MBSFN area, the system will configure the corresponding radio frame carrying MBMS service and some subframes in the radio frame for the area according to the MBMS service-related information in the MBSFN area, such as the number of MBMS services, It is used to send MBMS services in this MBSFN area.

Abstract

A notification method for an information change of a Multimedia Broadcast Multicast Service Control Channel (MCCH) comprises: a base station side indicates with a Multimedia Broadcast Multicast Service Radio Network Temporary Identity (M-RNTI) that information of an MCCH has a change, and notifies a User Equipment (UE) side; after detecting the M-RNTI, the UE continues reading the information of the MCCH or determines whether to continue reading the changed information of the MCCH according to service requirements of itself. A notification system for an information change of an MCCH comprises a notification unit on a base station side. When the base station side indicates with an M-RNTI that the information of the MCCH has a change, the notification unit on the base station side notifies the UE side. The notification mechanism for an information change of an MCCH is implemented by the method and the system. The UE monitors an information change of an MCCH, and the power consumption of the UE is reduced accordingly.

Description

technical field [0001] The present invention relates to a notification technology of control channel update in a long term evolution (LTE, Long Term Evolution) system, in particular to a notification method and system for a multimedia broadcast and multicast service (MBMS, Multimedia Broadcast Multicast Service) control channel update. Background technique [0002] With the rapid development of the Internet and the popularization of large-screen multifunctional mobile phones, a large number of mobile data multimedia services and various high-bandwidth multimedia services have emerged, such as: video conferencing, TV broadcasting, video on demand, advertising, online education, interactive games, etc. It not only satisfies the ever-increasing business demands of mobile users, but also brings new business growth points to mobile operators. These mobile data multimedia services require multiple users to receive the same data at the same time. Compared with general data services...
