[0035] To enable those skilled in the art to better understand the embodiments of the present application, the following description is provided first.

[0036] 1. Related description of LTE MBMS.

[0037] The transmission methods of the Multimedia Broadcast Multicast Service (MBMS) include the following two methods:

[0038] MBMS Transmission Method 1: Transmitted through the Physical Multicast Channel (PMCH) in the Multimedia Broadcast multicast service Single Frequency Network (MBMS SFN) subframe. Among them, the control channel is transmitted through system information (such as SIB13) and the Multicast Control Channel (MCCH), and the data is transmitted through the Multicast Traffic Channel (MTCH).

[0039] MBMS Transmission Method 2: Single Cell Point To Multiploint (SC-PTM):

[0040] Transmitted through the Physical Downlink Shared Channel (PDSCH) scheduled by the Physical Downlink Control Channel (PDCCH). Among them, the control information is transmitted through system information (such as SIB20) and the Single Cell Multicast Control Channel (SC-MCCH), and the data is transmitted through the Single Cell Multicast Traffic Channel (SC-MTCH). Among them, the SC-MCCH is transmitted through the PDSCH scheduled by the Physical Downlink Control Channel (PDCCH) with the Single Cell Radio Network Temporary Identity (SC-RNTI), and the SC-MTCH is transmitted through the PDSCH scheduled by the Physical Downlink Control Channel (PDCCH) with the Group Radio Network Temporary Identity (G-RNTI).

[0041] 2. LTE MBMS SC-PTM Service Continuity:

[0042] User Service Description (USD): Before the MBMS service starts, the network will inform the UE of the USD; in the USD, the application / service layer provides the Temporary Mobile Group Identity (TMGI), session start and end times, frequency, and the Service Area Identity (SAI) of the MBMS service area belonging to the MBMS service area for each service.

[0043] The SAI(s) of the current frequency and neighboring frequencies are provided in the system information block (SIB) 15. If one or more values in the SAI(s) of a certain frequency are the same as the SAI(s) in the USD, then the UE will consider that this frequency can provide this MBMS service. It should be noted that both MBMS cells and non-MBMS cells can provide SIB15 as long as the cell is the Primary cell (Pcell).

[0044] SIB20 provides information for obtaining the SC-MCCH; the control information for SC-PTM is in the SC-MCCH, and this information provides the scheduling information of all MBMS services in the current cell and the support situation of neighboring cells for each MBMS service supported by this cell. It should be noted that only MBMS cells can provide SIB15 and the cell is the Primary cell (Pcell).

[0045] 3. LTE MBMS cell reselection priority:

[0046] If the UE can perform SC-PTM reception, and the UE is receiving or interested in receiving the MBMS service, and can only receive this MBMS service when staying on the frequency that provides this MBMS service, then the UE can consider this frequency as the highest priority during the MBMS session.

[0047] Next, in conjunction with the accompanying drawings, through specific embodiments and their application scenarios, the information transmission method provided by the embodiments of the present application will be described in detail.

[0048] As Figure 2 shown, the embodiments of the present application provide an information transmission method applied to a terminal, and the method includes:

[0049] Step 201: Obtain the configuration information of the multicast and broadcast service through the Radio Resource Control (RRC) signaling.

[0050] Optionally, the configuration information of the multicast and broadcast service (MBS) includes at least one of the following:

[0051] Information related to the scheduling of Multicast Broadcast Service (MBS);

[0052] Information related to the service continuity of Multicast Broadcast Service (MBS).

[0053] The above-mentioned information related to MBS scheduling may specifically be the scheduling information of the MBS service. The above-mentioned information related to the service continuity of MBS is, for example, the situation of multicast broadcast services supported by the current frequency or neighboring frequencies (such as SAI in LTE), the situation of multicast broadcast services supported by the current cell (such as TMGI in LTE), and all other information related to service continuity.

[0054] In the embodiments of the present application, the configuration information of the MBS service is sent through RRC signaling. Compared with the periodic sending of MCCH and SC-MCCH, the RRC signaling is sent according to the needs of each terminal, which reduces the signaling overhead and energy consumption in certain cases.

[0055] Optionally, obtaining the configuration information of the multicast broadcast service through the Radio Resource Control (RRC) signaling includes:

[0056] Initiating an RRC connection event;

[0057] Obtaining the configuration information of the multicast broadcast service through the RRC signaling in the RRC connection event;

[0058] Among them, the RRC connection event includes:

[0059] The RRC connection establishment process or the RRC connection resume process or the RRC connection re-establishment process.

[0060] It should be noted that the RRC connection establishment process (RRC connection establishment) corresponds to the UE in the idle state (idle UE), the RRC connection resume process (RRC connection resume) corresponds to the UE in the inactive state (inactive UE), and the RRC connection re-establishment process (RRC connection re-establishment) corresponds to the UE in the connected state (RRC Connected UE).

[0061] In the embodiments of the present application, the UE obtains the configuration information of the MBS service by initiating the RRC connection establishment process or the RRC connection resume process or the RRC connection re-establishment process.

[0062] Optionally, the initiation conditions of the RRC connection event include at least one of the following:

[0063] The terminal has the capability of multicast and broadcast services;

[0064] The terminal is interested in multicast and broadcast services;

[0065] The terminal is receiving multicast and broadcast services;

[0066] The configuration of the multicast and broadcast services is updated.

[0067] Whether initiating an RRC connection establishment process, an RRC connection resume process, or an RRC connection re - establishment process, the following is satisfied for at least one of the following: The UE has MBS capabilities; The UE is interested in MBS; The UE is receiving MBS; The configuration of MBS is updated.

[0068] Optionally, the cause value in the RRC connection event is a defined cause value or a newly set cause value;

[0069] Among them, the defined cause value can be used for MBS configuration. Among them, the newly set cause value is a cause value different from the defined cause value.

[0070] The cause value in the RRC connection event includes at least one of the following:

[0071] The value of the establishment cause during the RRC connection establishment process;

[0072] The value of the resume cause during the RRC connection resume process;

[0073] The value of the re - establishment cause during the RRC connection re - establishment process. The value of the above - mentioned establishment cause is used to indicate the establishment cause in the RRC establishment request; the value of the above - mentioned resume cause is used to indicate the resume cause in the RRC resume request; the value of the above - mentioned re - establishment cause is used to indicate the re - establishment cause in the RRC re - establishment request.

[0074] Optionally, the above - mentioned newly set cause value is a cause value different from the defined cause value and can be used for MBS configuration.

[0075] For example, the value of the defined establishmentCause, or the value of the defined resumeCause, or the value of the defined reestablishmentCause may be: mo-Data, mo-Signalling, etc.; the value of the newly set establishmentCause, or the value of the newly set resumeCause, or the value of the newly set reestablishmentCause may be MBSConfiguration, etc.

[0076] Optionally, the Unified Access Control (UAC) in the RRC connection establishment process or the RRC connection resume process includes at least one of the following:

[0077] No UAC check is required and the access attempt is directly allowed;

[0078] The defined access value; where the defined access value can be used in the case of MBS configuration.

[0079] The newly set access value, which is a different access value from the defined access value; where the newly set access value can be used in the case of MBS configuration.

[0080] Wherein, the access value includes at least one of the value of the access category and the value of the access identity.

[0081] The access value includes at least one of the value of the Access category and the value of the Access identity(ies). The newly set access value is a different access value from the defined access value. Specific examples are, for instance, using the defined access value with Access category being 7 and Access identity being 0, and using the newly set access value with Access category being 11 and Access identity being 6.

[0082] Optionally, the RRC signaling includes at least one of the following:

[0083] RRC Reject message;

[0084] RRC Reestablishment message;

[0085] RRC Setup message;

[0086] RRC Resume message;

[0087] RRC Release message.

[0088] For example, as Figure 3 shown, during the RRC connection establishment process, the terminal sends an RRC establishment request to the network side, the network side sends an RRC establishment message to the terminal, and the terminal sends an RRC establishment completion message to the network side. Then, the configuration information of the above MBS can be obtained through the RRC establishment message sent by the network side.

[0089] As Figure 4 shown, during the RRC connection establishment process, the terminal sends an RRC connection establishment request to the network side, and the network side sends an RRC rejection message to the terminal. Then, the configuration information of the above MBS can be obtained through the RRC rejection message sent by the network side.

[0090] As Figure 5 shown, during the RRC connection resume process, the terminal sends an RRC resume request to the network side, the network side sends an RRC resume message to the terminal, and the terminal sends an RRC resume completion message to the network side. Then, the terminal can obtain the configuration information of the above MBS through the RRC resume message sent by the network side.

[0091] During the RRC connection re - establishment process, as Figure 6 shown, the terminal sends an RRC connection re - establishment request to the network side, and the network side responds to the RRC connection re - establishment and sends an RRC connection re - establishment message, and the RRC connection is re - established between the terminal and the network side; or, as Figure 7 shown, the network side responds to the RRC connection re - establishment and sends an RRC establishment message, and an RRC connection is established between the terminal and the network side. Then, the configuration information of the above MBS can be obtained through the RRC connection re - establishment message or the RRC establishment message.

[0092] Optionally, the information transmission method of the embodiments of the present application further includes:

[0093] Obtaining an indication message, where the indication message is used to indicate whether the configuration information of the multicast broadcast service has changed.

[0094] Further optionally, the indication message is a short message, and the first bit or the second bit in the short message is used to indicate whether the configuration information has changed, where the first bit refers to at least one bit that has been used in the short message, and the second bit refers to at least one bit that has not been used in the short message;

[0095] Alternatively, the indication message is downlink control information scrambled by a first radio network temporary identifier (RNTI), and the first RNTI refers to an RNTI different from the defined RNTIs.

[0096] For example, one or more of the first to third bits that have already been used in the short message are used to indicate whether the configuration information of the MBS service has changed; alternatively, one or more of the fourth to eighth bits that have not been used in the short message are used to indicate whether the configuration information of the MBS service has changed; or alternatively, a downlink control information (DCI) scrambled by a new RNTI, such as an X-RNTI, is used to indicate whether the configuration information of the MBS service has changed.

[0097] The short message is transmitted via a physical downlink control channel (PDCCH) scrambled by a P-RNTI and is in DCI format 1_0. Among them, bit 1 is the most significant bit.

[0098] Among them, the first bit of the short message is the system information modification indication. If it is set to 1, it means that the content of the broadcast control channel (BCCH) has changed except for SIB6, SIB7, and SIB8; the second bit is the earthquake and tsunami warning system (Etws) and commercial mobile alert system (Cmas) indication. If it is set to 1, it indicates an Etws primary notification and / or an Etws secondary notification and / or a Cmas notification; the third bit is the stop paging monitoring indication. If it is set to 1, it means that in this paging occasion (PO), the UE stops listening to the PDCCH occasion for transmitting paging messages; the fourth to eighth bits indicate that they are not used in this version of the specification, and the UE should ignore them if received. In addition, all UEs will listen to the PDCCH addressed by the P-PNTI and determine whether the system information has changed and whether to stop listening to paging based on the values of the respective bits in this DCI.

[0099] Optionally, the terminals to which the first RNTI applies include at least one of the following:

[0100] Terminals with multicast / broadcast service capabilities;

[0101] Terminals interested in multicast / broadcast services;

[0102] All terminals.

[0103] In an embodiment of the present application, the configuration information of the MBS service is sent to the UE through dedicated RRC signaling, and the change of the configuration of the MBS service is indicated through a short message mechanism, etc. Compared with the periodic transmission of MCCH and SC-MCCH, the RRC dedicated signaling is sent according to the needs of each terminal, which reduces the signaling overhead and energy consumption in certain cases.

[0104] As Figure 8 shown, an embodiment of the present application also provides an information transmission method, which is applied to a network-side device and includes:

[0109] The above information related to MBS scheduling may specifically be the scheduling information of the MBS service. The above information related to the service continuity of MBS is, for example, the situation of multicast and broadcast services supported by the current frequency or neighboring frequencies (such as SAI in LTE), the situation of multicast and broadcast services supported by the current cell (such as TMGI in LTE), etc., all information related to service continuity. In an embodiment of the present application, the configuration information of the MBS service is sent to the UE through dedicated RRC signaling.
