In making the description of the embodiments of the present invention, some concepts used in the following description will first be explained.

A notification mechanism of MBMS control information change under Single Cell-Point to Multipoint (SC-PTM) technology:

when the MBMS service on the serving Cell changes, the content of an MBMS Control message transmitted on an MBMS Control Channel (SC-MCCH) may be changed. When the MBMS control message changes, the UE needs to acquire the updated MBMS control message in time. In order to avoid unnecessary power consumption caused by continuous monitoring of the MBMS control channel by the UE for acquiring the updated MBMS control message, a special MBMS control message change notification mechanism is designed on the SC-PTM, as shown in fig. 1, a special Modification Period (Modification Period) and a repetition Period (repetition Period) are defined for the change of the transmission of the MBMS control message, the network controls to update the MBMS control information only at a specific position within the Modification Period, and the MBMS control message updated within one Modification Period may be repeatedly transmitted every other repetition Period.

If the change of the MBMS control message occurs, the access network indicates through one bit of DCI information with a specific format on the PDCCH, and the PDCCH used for indicating is scrambled through a specific RNTI (namely SC-N-RNTI) so as to be distinguished by the UE. The UE which is not in an idle state and does not receive the MBMS but is interested in the MBMS only needs to monitor the PDCCH indicated by the SC-N-RNTI at a specific position so as to judge whether the MBMS control message is changed or not, and then receives the updated MBMS control message according to the indication.

When the MBMS control message indicated by one information bit in DCI on the PDCCH indicated by SC-N-RNTI changes, the MBMS control message on the SC-MCCH changes due to the change of any MBMS service in a cell, all UEs in the cell need to acquire the updated multicast control message according to the indication of the PDCCH DCI, and only after the updated multicast control message is acquired, whether the MBMS concerned by the UE changes can be known, so that the change of part of MBMS services can cause the UE to unnecessarily receive the updated MBMS control message.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Specifically, as shown in fig. 2, an embodiment of the present invention provides a method for notifying a change of an MBMS control message, which is applied to a terminal, and includes:

step 201, receiving an MBMS control message update indication of a target MBMS service in a transmission manner corresponding to an MBMS service group to which the target MBMS service belongs according to a plurality of MBMS service groups into which a multimedia broadcast multicast service MBMS is divided.

In this embodiment, the network side device divides all MBMS services in a cell into a plurality of MBMS service groups. Optionally, the MBMS service identifier may be divided according to, for example: according to the Temporary Mobile Group Identity (TMGI), each TMGI belongs to a different MBMS service Group, and the network side device needs to configure parameters required for MBMS service grouping to the terminal, and the terminal can know the MBMS service Group to which the concerned MBMS service belongs according to the parameters required for MBMS service grouping. When the MBMS service changes to cause the MBMS control message to change, the network side equipment sends an MBMS control message updating indication to the terminal according to the transmission mode corresponding to the MBMS service group, and the terminal monitors the MBMS control message updating indication of the target MBMS service according to the transmission mode corresponding to the MBMS service group to which the target MBMS service concerned belongs and correspondingly receives the updated MBMS control message.

According to the embodiment of the application, for the change of the MBMS control message on the MBMS control channel, the network side carries out grouping notification according to the MBMS service group to which the MBMS service belongs, and the terminal receives the MBMS control message updating indication according to the MBMS service group to which the target MBMS service belongs, so that the process that the UE receives the MBMS control message updating indication irrelevant to the UE is reduced, and unnecessary power consumption is avoided.

Specifically, before receiving an MBMS control message update indication of a target MBMS service in a transmission manner corresponding to an MBMS service group to which the target MBMS service belongs, the method further includes:

receiving an indication parameter for dividing the MBMS into a plurality of MBMS service groups; and determining a target MBMS service group to which the target MBMS service belongs according to the indication parameters.

When the network side device groups all MBMS services in a cell, it needs to send parameters and grouping indications according to the grouping to the terminal, for example: number of packets, grouping algorithm. The terminal can determine the MBMS group to which each MBMS belongs according to the indication and the related parameters of the network side equipment, so that the MBMS groups are consistent with the grouping of the network side equipment. For example: the network side equipment groups the MBMS services according to MBMS service identifications (such as TMGI), wherein the same service identification belongs to the same MBMS service group, or the MBMS services with the service identification values in a preset interval belong to the same MBMS service group. It should be noted that, the specific basis for grouping the MBMS services is not limited, and may be set according to the requirement.

Further, when receiving an MBMS control message update indication of a target MBMS service in a transmission manner corresponding to an MBMS service group to which the target MBMS service belongs according to a plurality of MBMS service groups into which the MBMS service is divided, the following manners may be included, but are not limited to:

the first method is as follows: the change of the MBMS control information corresponding to different MBMS services is indicated at different time points.

Specifically, the step 201 includes: monitoring a physical downlink control channel PDCCH (physical downlink control channel) indicated by a radio network temporary identifier SC-N-RNTI (radio network temporary identifier) notified by a single cell at a target receiving time point corresponding to the target MBMS service group; and the downlink control information DCI in the PDCCH carries the MBMS control message updating indication.

In this embodiment, after the network side device groups all MBMS services in a cell, DCI information on a PDCCH indicated by an SC-N-RNTI is used at different time points within a modification period of an MBMS control channel to carry a corresponding service change notification of each MBMS service group, that is, a service change notification of one MBMS service group is corresponding to each time point. And the terminal monitors the PDCCH indicated by the SC-N-RNTI at the receiving time point corresponding to the target MBMS service group according to the target MBMS service group to which the target MBMS service belongs, and receives the updated MBMS control message at the corresponding position when the DCI information in the PDCCH is monitored to carry the MBMS control message updating indication.

Specifically, before receiving an MBMS control message update indication of a target MBMS service in a transmission manner corresponding to an MBMS service group to which the target MBMS service belongs, the method further includes: and receiving the information of the receiving time point corresponding to each MBMS service group. In order to implement the first mode, before sending an MBMS control message update indication to a terminal, a network side device needs to configure, to a UE, parameters required for MBMS service grouping and related parameters of a transmission time point of a change notification of each MBMS service group, such as a time offset from a start point of a modification period, so that the terminal can monitor a PDCCH indicated by an SC-N-RNTI at the corresponding time point.

The following describes an implementation process of the first mode by using a specific example.

Example one, as shown in fig. 3:

1): and the UE receives related parameters of the MBMS service grouping, such as the grouping number and the grouping algorithm, sent by the network side equipment. And calculates the MBMS service group corresponding to the MBMS service concerned by the UE (i.e., the target MBMS service group corresponding to the target MBMS service). The UE receives the relevant parameters of the sending time point of the service change notification of each MBMS service group, such as the time offset from the start point of the modification period.

2): the UE monitors a PDCCH indicated by a corresponding SC-N-RNTI at a receiving time point corresponding to a target MBMS service group;

3): when the UE receives the MBMS control message update indication on the PDCCH, it receives the updated MBMS control message to the corresponding location.

The second method comprises the following steps: and indicating the positions of the changes of the MBMS control information corresponding to different MBMS services in different frequency domains at the same time point.

Specifically, the step 201 may include: monitoring a PDCCH indicated by SC-N-RNTI on a target frequency domain resource corresponding to the target MBMS service group; and the DCI information in the PDCCH carries the MBMS control message updating indication.

In this embodiment, after the network side device groups all MBMS services in a cell, the DCI information on the PDCCH indicated by the same SC-N-RNTI is used on different frequency domain resources within the modification period of the MBMS control channel to carry a service change notification corresponding to each MBMS service group, that is, the DCI information on each frequency domain resource corresponds to the service change notification of one MBMS service group. And the terminal monitors a PDCCH (physical downlink control channel) indicated by the SC-N-RNTI (service center-network temporary identifier) on a target frequency domain resource corresponding to the target MBMS service group according to the target MBMS service group to which the target MBMS service belongs, and receives the updated MBMS control message at a corresponding position when monitoring that the DCI information in the PDCCH carries the MBMS control message updating indication.

Specifically, before receiving an MBMS control message update indication of a target MBMS service in a transmission manner corresponding to an MBMS service group to which the target MBMS service belongs, the method further includes: and receiving the information of the frequency domain resource corresponding to each MBMS service group. In order to implement the second method, before sending the MBMS control message update indication to the terminal, the network side device needs to configure parameters required for MBMS service grouping and related parameters of frequency domain resources corresponding to each MBMS service group change notification, such as frequency domain offset, to the terminal. So that the terminal can monitor the PDCCH indicated by the SC-N-RNTI at the corresponding frequency domain resource position.

The following describes the implementation process of the second mode by using a specific example.

Example two, as shown in fig. 4:

1): and the UE receives related parameters of the MBMS service grouping, such as the grouping number and the grouping algorithm, sent by the network side equipment. And calculates the MBMS service group corresponding to the MBMS service concerned by the UE (i.e., the target MBMS service group corresponding to the target MBMS service). And the UE simultaneously receives the related parameters of the frequency domain resources, such as frequency domain offset and the like, sent by the service change notification of each MBMS service group.

2): the UE monitors a PDCCH indicated by the SC-N-RNTI on a frequency domain resource corresponding to a target MBMS service group;

3): when the UE receives the MBMS control message change indication on the PDCCH, it receives the updated MBMS control message to the corresponding location.

The third method comprises the following steps: different MBMS service groups correspond to different SC-N-RNTI values.

Specifically, the step 201 may include: monitoring a PDCCH indicated by a target SC-N-RNTI corresponding to the target MBMS service group; and the DCI information of the PDCCH indicated by the target SC-N-RNTI carries the MBMS control message updating indication.

In this embodiment, after the network side device groups all MBMS services in a cell, each MBMS service group uses DCI information on a PDCCH indicated by an independent SC-N-RNTI to indicate a service change, and UEs belonging to different MBMS service groups only need to monitor a PDCCH channel indicated by a corresponding SC-N-RNTI (i.e., a target SC-N-RNTI). The terminal monitors the PDCCH indicated by the objective SC-N-RNTI corresponding to the MBMS service group to which the UE belongs, and receives the updated MBMS control message at the corresponding position when receiving the MBMS control message updating indication.

Optionally, before receiving an MBMS control message update indication of a target MBMS service in a transmission manner corresponding to an MBMS service group to which the target MBMS service belongs, the method further includes: and receiving the information of the SC-N-RNTI value corresponding to each MBMS service group. In order to implement the third method, before sending an MBMS control message update indication to the terminal, the network side device needs to configure parameters required for MBMS service grouping and values of SC-N-RNTI corresponding to each MBMS service group to the terminal. So that the terminal can monitor the PDCCH indicated by the target SC-N-RNTI corresponding to the target MBMS service group.

The following describes the implementation process of the third mode by a specific example.

Example three, as shown in fig. 5:

1): and the UE receives related parameters of the MBMS service grouping, such as the grouping number and the grouping algorithm, sent by the network side equipment. And calculates the MBMS service group corresponding to the MBMS service concerned by the UE (i.e., the target MBMS service group corresponding to the target MBMS service). The UE simultaneously receives the value of SC-N-RNTI corresponding to each MBMS service group sent by the network side equipment;

2): the UE monitors a PDCCH indicated by a target SC-N-RNTI corresponding to a target MBMS service group;

The method is as follows: the information bits in the downlink control information DCI on the PDCCH indicate the change of different MBMS service groups, respectively.

Specifically, the step 201 may include: monitoring a PDCCH indicated by SC-N-RNTI in an MBMS control channel modification period; the DCI information of the PDCCH includes: and target information bits corresponding to the target MBMS service group, wherein the target information bits indicate the updating condition of the MBMS control message corresponding to the target MBMS service.

In this embodiment, after grouping all MBMS services in a cell, a network side device adds information bits to a format of DCI information in a PDCCH indicated by an SC-N-RNTI, where each information bit corresponds to a different MBMS service group, and is used to indicate whether an MBMS service in the corresponding MBMS service group has changed. The terminal monitors a PDCCH indicated by a network side device through a radio access network temporary identifier (such as SC-N-RNTI), detects a target information bit on the PDCCH corresponding to an MBMS service group (namely a target MBMS service group corresponding to the target MBMS service) to which the MBMS concerned by the UE belongs, and receives an updated MBMS control message at a corresponding position when the corresponding information bit indicates an MBMS control message update indication.

Optionally, before receiving an MBMS control message update indication of a target MBMS service in a transmission manner corresponding to an MBMS service group to which the target MBMS service belongs, the method may further include: and receiving information of information bits of the DCI information corresponding to each MBMS service group. In order to implement the fourth embodiment, before sending an MBMS control message update indication to the terminal, the network side device needs to define a new DCI format, so that different information bits in the DCI format indicate MBMS service groups of different MBMS service groups, and the network side device needs to configure parameters required for MBMS service grouping and information of information bits of DCI information corresponding to each MBMS service group to the terminal, so that the terminal detects an indication content of target information bits corresponding to a target service group.

The implementation process of the fourth mode is described below by a specific example.

Example four, as shown in fig. 6:

1): and the UE receives related parameters of the MBMS service grouping, such as the grouping number and the grouping algorithm, sent by the network side equipment. And calculates the MBMS service group corresponding to the MBMS concerned by the UE (namely the target MBMS service group corresponding to the target MBMS service);

2): the UE starts to monitor a PDCCH indicated by a radio access network temporary identifier (such as SC-N-RNTI) in an MBMS control channel modification period;

3): when the target MBMS changes, the network side equipment sets the target information bit in the DCI on the corresponding PDCCH according to the target MBMS group corresponding to the target MBMS and sends the target information bit to the UE.

4): the UE detects the change of the MBMS control message corresponding to the target MBMS service group in the target information bit of the PDCCH indicated by the temporary identifier (such as SC-N-RNTI) of the radio access network;

5): and the UE receives the updated MBMS control message on the MBMS control channel of the corresponding position.

The foregoing describes four implementation manners for receiving an MBMS control message update indication of a target MBMS service through a transmission manner corresponding to an MBMS service group to which the target MBMS service belongs, and it should be noted that the embodiments of the present application include, but are not limited to, the above-mentioned manner for receiving an MBMS control message update indication, and in a case of grouping MBMS services, the manner for receiving an MBMS control message update indication of a target MBMS service is within the protection scope of the present application.

Optionally, after receiving an MBMS control message update indication of a target MBMS service in a transmission manner corresponding to an MBMS service group to which the target MBMS service belongs, the method further includes: and receiving the MBMS control message updated by the target MBMS service according to the MBMS control message updating indication. And the terminal can receive the updated MBMS control message after receiving the MBMS control message updating indication according to the transmission mode corresponding to the MBMS service group to which the target MBMS service belongs.

As shown in fig. 7, an embodiment of the present invention further provides a method for notifying a change of an MBMS control message, which is applied to a network side device, and includes:

step 701: according to a plurality of MBMS service groups into which the MBMS service is divided, under the condition that an MBMS control message corresponding to a target MBMS service changes, an MBMS control message updating indication is sent to a terminal through a transmission mode corresponding to the MBMS service group to which the target MBMS service belongs.

In this embodiment, the network side device divides all MBMS services in a cell into a plurality of MBMS service groups. Optionally, the MBMS service identifier may be divided according to, for example: according to the TMGI division, each TMGI belongs to a different MBMS service group, and the network side device needs to configure parameters, such as the number of packets, the grouping algorithm, etc., required for grouping the MBMS services to the terminal. So that the terminal can know the MBMS service group to which the MBMS service belongs.

When the MBMS service changes to cause the change of the MBMS control message, the network side equipment sends an MBMS control message updating indication to the terminal according to the transmission mode corresponding to the MBMS service group, so that the terminal monitors the MBMS control message updating indication of the target MBMS service.

In the embodiment, for the change of the MBMS control message on the MBMS control channel, the network side divides all the MBMS services in the cell into a plurality of MBMS service groups, and when the MBMS control message corresponding to the target MBMS service changes, the grouping notification is carried out according to the MBMS service group to which the target MBMS service belongs, so that the terminal receives the MBMS control message updating indication according to the MBMS service group to which the target MBMS service belongs, the process that the UE receives the MBMS control message updating indication irrelevant to the UE is reduced, and unnecessary power consumption is avoided.

Optionally, when grouping the MBMS service, the MBMS service may be grouped according to an MBMS service identifier of the MBMS service; wherein, different MBMS service identifications correspond to different MBMS service groups. After grouping the MBMS service according to an MBMS service identifier of the MBMS service, the method further includes: and sending an indication parameter for dividing the MBMS into a plurality of MBMS service groups to the terminal.

When the network side device groups all MBMS services in a cell, it needs to send the parameters according to the grouping and the grouping indication to the terminal, for example: grouping quantity and a grouping algorithm, so that the terminal determines the MBMS group to which the MBMS belongs according to the indication of the network side equipment and the related parameters. For example: the network side equipment groups the MBMS services according to MBMS service identifications (such as TMGI), wherein the same service identification belongs to the same MBMS service group, or the MBMS services with the service identification values in a preset interval belong to the same MBMS service group. It should be noted that, the specific basis for grouping the MBMS services is not limited, and may be set according to the requirement.

Further, the step 701 may include: transmitting the MBMS control message updating indication at a target receiving time point corresponding to the target MBMS service group; and the MBMS control message updating indication is carried by downlink control information DCI in a physical downlink control channel PDCCH indicated by a single cell informing radio network temporary identifier SC-N-RNTI.

In this embodiment, after the network side device groups all MBMS services in a cell, DCI information on a PDCCH indicated by an SC-N-RNTI is used at different time points within a modification period of an MBMS control channel to carry a corresponding service change notification of each MBMS service group, that is, a service change notification of one MBMS service group is corresponding to each time point.

Specifically, before sending an MBMS control message update indication to a terminal in a transmission manner corresponding to an MBMS service group to which the target MBMS service belongs, the method further includes: configuring a receiving time point corresponding to each MBMS service group; and sending the information of the receiving time point corresponding to each MBMS service group to a terminal. Before sending an MBMS control message update indication to a terminal, a network side device needs to configure parameters required for MBMS service grouping and related parameters of a transmission time point of a change notification of each MBMS service group, such as a time offset from a start point of a modification period, to a UE, so that the terminal can monitor a PDCCH indicated by an SC-N-RNTI at a corresponding time point.

And the terminal monitors the PDCCH indicated by the SC-N-RNTI at the receiving time point corresponding to the target MBMS service group according to the target MBMS service group to which the target MBMS service belongs, and receives the updated MBMS control message at the corresponding position when the DCI information in the PDCCH is monitored to carry the MBMS control message updating indication.

Further, the step 701 may include: transmitting the MBMS control message updating indication on the target frequency domain resource corresponding to the target MBMS service group; and the MBMS control message updating indication is carried by DCI in the PDCCH indicated by the SC-N-RNTI.

In this embodiment, after the network side device groups all MBMS services in a cell, the DCI information on the PDCCH indicated by the same SC-N-RNTI is used on different frequency domain resources within the modification period of the MBMS control channel to carry a service change notification corresponding to each MBMS service group, that is, the DCI information on each frequency domain resource corresponds to the service change notification of one MBMS service group.

Before sending an MBMS control message update indication to a terminal in a transmission manner corresponding to an MBMS service group to which the target MBMS service belongs, the method further includes: configuring frequency domain resources corresponding to each MBMS service group; and sending the information of the frequency domain resource corresponding to each MBMS service group to a terminal. Before sending an MBMS control message update indication to a terminal, a network side device needs to configure parameters required for MBMS service grouping and related parameters of frequency domain resources corresponding to each MBMS service group change notification, such as frequency domain offset, to the terminal. So that the terminal can monitor the PDCCH indicated by the SC-N-RNTI at the corresponding frequency domain resource position.

And the terminal monitors a PDCCH (physical downlink control channel) indicated by the SC-N-RNTI (service center-network temporary identifier) on a target frequency domain resource corresponding to the target MBMS service group according to the target MBMS service group to which the target MBMS service belongs, and receives the updated MBMS control message at a corresponding position when monitoring that the DCI information in the PDCCH carries the MBMS control message updating indication.

Further, the step 701 may include: sending the value of a target SC-N-RNTI corresponding to the target MBMS service group to a terminal; and the MBMS control message updating indication is carried by DCI in the PDCCH indicated by the target SC-N-RNTI.

In this embodiment, after the network side device groups all MBMS services in a cell, each MBMS service group uses DCI information on a PDCCH indicated by an independent SC-N-RNTI to indicate a service change, and UEs belonging to different MBMS service groups only need to monitor a PDCCH channel indicated by a corresponding target SC-N-RNTI.

Before sending an MBMS control message update indication to a terminal in a transmission manner corresponding to an MBMS service group to which the target MBMS service belongs, the method further includes: configuring the value of SC-N-RNTI corresponding to each MBMS service group; and sending the information of the SC-N-RNTI value corresponding to each MBMS service group to a terminal. Before sending an MBMS control message update indication to a terminal, a network side device needs to configure parameters required for MBMS service grouping and values of SC-N-RNTIs corresponding to each MBMS service group to the terminal. So that the terminal can monitor the PDCCH indicated by the target SC-N-RNTI corresponding to the target MBMS service group.

The terminal monitors the PDCCH indicated by the objective SC-N-RNTI corresponding to the MBMS service group to which the UE belongs, and receives the updated MBMS control message at the corresponding position when receiving the MBMS control message updating indication.

Further, the step 701 may include: sending DCI information of the PDCCH indicated by the SC-N-RNTI to a terminal; the DCI information includes: and target information bits corresponding to the target MBMS service group, wherein the target information bits indicate the updating condition of the MBMS control message corresponding to the target MBMS service.

In this embodiment, after grouping all MBMS services in a cell, a network side device adds information bits to a format of DCI information in a PDCCH indicated by an SC-N-RNTI, where each information bit corresponds to a different MBMS service group, and is used to indicate whether an MBMS service in the corresponding MBMS service group has changed.

Optionally, before sending an MBMS control message update indication to the terminal through a transmission mode corresponding to the MBMS service group to which the target MBMS service belongs, the method further includes: configuring information bits in DCI information corresponding to each MBMS service group; and sending the information of the information bits of the DCI information corresponding to each MBMS service group to a terminal. Before sending an MBMS control message update indication to a terminal, a network side device needs to define a new DCI format, so that different information bits therein indicate MBMS service groups of different MBMS service groups, and the network side device needs to configure, to the terminal, parameters required for MBMS service grouping and information bits of DCI information corresponding to each MBMS service group, so that the terminal detects an indication content of a target information bit corresponding to a target service group.

The terminal monitors a PDCCH indicated by a radio access network temporary identifier (such as SC-N-RNTI) of network side equipment, checks a target information bit on the PDCCH corresponding to a target MBMS group corresponding to a target MBMS of the UE, and receives an updated MBMS control message at a corresponding position when the corresponding information bit indicates an MBMS control message update indication.

The foregoing describes four implementation manners of sending an MBMS control message update indication to a terminal through a transmission manner corresponding to an MBMS service group to which the target MBMS service belongs by using specific embodiments, and it should be noted that the embodiments of the present application include, but are not limited to, the above-mentioned manner of sending an MBMS control message update indication, and in a case of grouping MBMS services, the manner of sending an MBMS control message update indication of the target MBMS service can be implemented within the protection scope of the present application.
