Abstract
A multicast service information change notification method comprises: an access network element sends to a UE a multicast service information update command; and the access network element indicates multicast service information to the UE service.
Claims12
A method for notifying service information change of multicast service, comprising:
- sending, by an access network element, in downlink control information (DCI) of a physical downlink control channel (PDCCH) scheduling a single cell-multicast traffic channel (SC-MTCH) or in a medium access control (MAC) protocol data unit (PDU) carrying a SC-MTCH data, a change notification of single cell-multicast control channel (SC-MCCH) information, wherein the DCI comprises a one-bit indicator to indicate the SC-MCCH information has updated content related to the SC-MTCH;
- wherein the updated content indicated by the access network element in the DCI of the PDCCH scheduling the SC-MTCH or in the MAC PDU carrying the SC-MTCH data comprises one or more combinations of the following:
- a one-bit indicator to indicate whether update of the SC-MCCH information is related to the SC-MTCH, or to indicate whether the SC-MCCH information has the updated content related to the SC-MTCH;
- and
- a one-bit indicator to indicate whether there is updated content of the SC-MCCH information irrelevant to the SC-MTCH;
- wherein the access network element sends the change notification of the SC-MCCH information in one or more of following cases:
- when the SC-MCCH information is changed, the access network element indicates, in the DCI of the PDCCH scheduling the SC-MTCH or in the MAC PDU carrying the SC-MTCH data, the SC-MCCH information is changed;
- when configuration information related to the SC-MTCH in the SC-MCCH information is changed, the access network element indicates, in the DCI of the PDCCH scheduling the SC-MTCH or in the MAC PDU carrying the SC-MTCH data, whether content of the SC-MCCH information has changed content related to the SC-MTCH;
- when the content of the SC-MCCH information irrelevant to the SC-MTCH is changed, the access network element indicates, in the DCI of the PDCCH scheduling SC-MTCH or in the MAC PDU carrying the SC-MTCH data, that there is the updated content of the SC-MCCH information irrelevant to the SC-MTCH.
6 more elements
An access network element device, comprising:
- a memory, configured to store instructions;
- and
- a processor, configured to execute the instructions to perform:
- sending, in downlink control information (DCI) of a physical downlink control channel (PDCCH) scheduling a single cell-multicast traffic channel (SC-MTCH) or in a medium access control (MAC) protocol data unit (PDU) carrying a SC-MTCH data, a change notification of single cell-multicast control channel (SC-MCCH) information, wherein the DCI comprises a one-bit indicator to indicate the SC-MCCH information has updated content related to the SC-MTCH;
- wherein the updated content indicated by the access network element in the DCI of the PDCCH scheduling the SC-MTCH or in the MAC PDU carrying the SC-MTCH data comprises one or more combinations of the following:
- a one-bit indicator to indicate whether update of the SC-MCCH information is related to the SC-MTCH, or to indicate whether the SC-MCCH information has updated content related to the SC-MTCH;
- and
- a one-bit indicator to indicate whether there is updated content of the SC-MCCH information irrelevant to the SC-MTCH;
- wherein the processor is configured to send the change notification of the SC-MCCH information in one or more of following cases:
- when the SC-MCCH information is changed, the access network element indicates, in the DCI of the PDCCH scheduling the SC-MTCH or in the MAC PDU carrying the SC-MTCH data, the SC-MCCH information is changed;
- when configuration information related to the SC-MTCH in the SC-MCCH information is changed, the access network element indicates, in the DCI of the PDCCH scheduling the SC-MTCH or in the MAC PDU carrying the SC-MTCH data, whether content of the SC-MCCH information has changed content related to the SC-MTCH;
- when the content of the SC-MCCH information irrelevant to the SC-MTCH is changed, the access network element indicates, in the DCI of the PDCCH scheduling SC-MTCH or in the MAC PDU carrying the SC-MTCH data, that there is updated content of the SC-MCCH information irrelevant to the SC-MTCH.
