In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following describes the technical solutions related to the embodiments of the present application.

With the pursuit of speed, delay, high speed mobility, energy efficiency and diversity and complexity of future life business, the third generation partnership project (3 ^rd Generation Partnership Project,3 GPP) international standards organization began developing 5G. The main application scenario of 5G is: enhanced mobile Ultra-wideband (enhanced Mobile Broadband, emmbb), low latency high reliability communication (URLLC), large-scale Machine-based communication (mctc).

On the one hand, embbs still target users to obtain multimedia content, services and data, and their demand is growing very rapidly. On the other hand, since an eMBB may be deployed in different scenarios, such as indoors, urban, rural, etc., its capabilities and requirements are also quite different, so that detailed analysis must be performed in connection with a specific deployment scenario, not in general. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety guarantee and the like. Typical characteristics of mctc include: high connection density, small data volume, delay insensitive traffic, low cost and long service life of the module, etc.

RRC state

5G for the purposes of reducing air interface signaling and fast recovery of radio connections, fast recovery of data traffic, a new radio resource control (Radio Resource Control, RRC) state, namely an RRC INACTIVE (RRC_INACTIVE) state, is defined. This state is different from the RRC IDLE (rrc_idle) state and the RRC ACTIVE (rrc_active) state. Wherein,

1) Rrc_idle state (simply referred to as IDLE state): mobility is UE-based cell selection reselection, paging is initiated by a Core Network (CN), and paging areas are configured by the CN. The base station side has no UE context and no RRC connection.

2) Rrc_connected state (CONNECTED state for short): there is an RRC connection and UE contexts on the base station side and UE side. The network side knows that the location of the UE is cell specific. Mobility is network-side controlled mobility. Unicast data may be transmitted between the UE and the base station.

3) Rrc_inactive state (simply referred to as INACTIVE state): mobility is cell selection reselection based on UE, there is a connection between CN-NRs, UE context exists on a certain base station, paging is triggered by RAN, paging area based on RAN is managed by RAN, network side knows UE location is based on paging area level of RAN.

MBMS

MBMS, a technology for transmitting data from one data source to a plurality of UEs through a shared network resource, is introduced in 3GPP Release 6 (R6), and is capable of effectively utilizing network resources while providing multimedia services, and realizing broadcasting and multicasting of multimedia services at a higher rate (e.g., 256 kbps).

Due to the low MBMS spectrum efficiency in 3gpp R6, it is not sufficient to effectively carry and support the operation of the mobile tv type service. In LTE, 3GPP has therefore explicitly proposed to enhance the support capability for the downlink high speed MBMS service and to determine the design requirements for the physical layer and the air interface.

The 3gpp R9 introduces evolved MBMS (eMBMS) into LTE. eMBMS proposes the concept of a single frequency network (Single Frequency Network, SFN), i.e. a multimedia broadcast multicast service single frequency network (Multimedia Broadcast multicast service Single Frequency Network, MBSFN), wherein the MBSFN uses a unified frequency to simultaneously transmit traffic data in all cells, but synchronization between the cells is guaranteed. The method can greatly improve the overall signal-to-noise ratio distribution of the cell, and the frequency spectrum efficiency can be correspondingly and greatly improved. eMBMS implements broadcast and multicast of services based on IP multicast protocols.

In LTE or LTE-Advanced (LTE-a), MBMS has only a broadcast bearer mode and no multicast bearer mode. In addition, the reception of the MBMS service is applicable to UEs in an idle state or a connected state.

A single cell point-to-multipoint (Single Cell Point To Multiploint, SC-PTM) concept is introduced in 3gpp r13, SC-PTM being based on the MBMS network architecture.

MBMS introduces new logical channels including Single Cell multicast control channel (SC-MCCH) and Single Cell multicast transport channel (SC-MTCH) and Single Cell-Multicast Transport Channel. The SC-MCCH and SC-MTCH are mapped onto a Downlink-Shared Channel (DL-SCH), and further, the DL-SCH is mapped onto a physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH), wherein the SC-MCCH and SC-MTCH belong to a logical Channel, the DL-SCH belongs to a transport Channel, and the PDSCH belongs to a physical Channel. The SC-MCCH and SC-MTCH do not support hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) operation.

MBMS introduces a new system information block (System Information Block, SIB) type, SIB20. Specifically, the configuration information of the SC-MCCH is transmitted through the SIB20, and one cell has only one SC-MCCH. The configuration information of the SC-MCCH comprises: the modification period of the SC-MCCH, the repetition period of the SC-MCCH, the radio frame and subframe for scheduling the SC-MCCH and other information. Further, 1) the boundary of the modification period of the SC-MCCH satisfies SFN mod m=0, where SFN represents a system frame number of the boundary, and m is a modification period (i.e., SC-MCCH-modification period) of the SC-MCCH configured in SIB20. 2) The radio frame of the scheduling SC-MCCH meets the following conditions: SFN mod MCCH-repetition period = MCCH-Offset, where SFN represents the system frame number of the radio frame, MCCH-repetition period represents the repetition period of the SC-MCCH, and MCCH-Offset represents the Offset of the SC-MCCH. 3) The subframes of the scheduling SC-MCCH are indicated by SC-MCCH-Subframe.

The SC-MCCH is scheduled through a physical downlink control channel (Physical Downlink Control Channel, PDCCH). In one aspect, a new radio network temporary identity (Radio Network Tempory Identity, RNTI), i.e., single Cell RNTI (SC-RNTI), is introduced to identify a PDCCH (e.g., SC-MCCH PDCCH) for scheduling the SC-MCCH, optionally with the SC-RNTI fixed value FFFC. On the other hand, a new RNTI, i.e., a single cell notification RNTI (Single Cell Notification RNTI, SC-N-RNTI) is introduced to identify a PDCCH (e.g., notification PDCCH) for indicating a change notification of the SC-MCCH, optionally, the SC-N-RNTI is fixed to a value of FFFB; further, the change notification may be indicated with one bit of 8 bits (bits) of DCI 1C. In LTE, the configuration information of SC-PTM is based on the SC-MCCH configured by SIB20, and then SC-MCCH configures SC-MTCH for transmitting service data.

Specifically, the SC-MCCH transmits only one message (i.e., scptm configuration) for configuring configuration information of the SC-PTM. The configuration information of the SC-PTM comprises: temporary mobile Group identity (Temporary Mobile Group Identity, TMGI), session identity (session id), group RNTI (G-RNTI), discontinuous reception (Discontinuous Reception, DRX) configuration information, SC-PTM service information of neighbor cells, and the like. Note that SC-PTM in R13 does not support the robust header compression (Robust Header Compression, ROHC) function.

The downlink discontinuous reception of the SC-PTM is controlled by the following parameters: onDurationTimerSCPTM, drx-InactivityTimerSCPTM, SC-MTCH-scheduling cycle, and SC-MTCH-scheduling offset.

When [ (SFN 10) +subframe number ] module (SC-MTCH-scheduling cycle) =sc-MTCH-scheduling offset is satisfied, a timer ondurationtimerscpm is started;

when receiving downlink PDCCH scheduling, starting a timer drx-InactivityTimerSCPTM;

the downstream SC-PTM service is received only when the timer onduration timerscpm or drx-incaactyitimerscpm is running.

The SC-PTM service continuity adopts the MBMS service continuity concept based on SIB15, namely a mode of SIB15 and MBMSInterestindication. The traffic continuity of idle state UEs is based on the concept of frequency priority.

In NR, many scenarios require supporting the traffic demands of multicasting and broadcasting, such as in the internet of vehicles, industrial internet, etc. It is necessary to introduce MBMS in the NR. It is clear how to configure MBMS configuration information in NR to achieve and optimize MBMS services. On the other hand, in LTE, the implementation of MBMS configuration information is to configure SC-MCCH through SIB20, and then configure SC-MTCH through SC-MCCH; the transmission of the SC-MCCH is based on the cell level, and the MBMS configuration information needs to be acquired again after the cell of the UE is changed, thereby introducing service interruption or service delay caused by the cell change. Furthermore, SIB in NR is sent based on UE request, so service interruption or service delay is further introduced after cell change. For this reason, the following technical solutions of the embodiments of the present application are proposed.

Fig. 2 is a flow chart of an information configuration method provided in an embodiment of the present application, as shown in fig. 2, where the information configuration method includes the following steps:

step 201: the terminal device receives a first SIB, where the first SIB includes configuration information of a first MCCH, where the first MCCH is used to carry first signaling, and the first signaling is used to determine configuration information of at least one first MTCH.

In the embodiment of the application, the network device sends a first SIB, and the terminal device receives the first SIB. Alternatively, the network device may be a base station, such as a gNB.

In this embodiment of the present application, a new SIB (referred to as a first SIB) is defined, referring to fig. 3, where the first SIB includes configuration information of a first MCCH, where the first MCCH is a control channel of an MBMS service, in other words, the first SIB is used to configure configuration information of a control channel of an NR MBMS, alternatively, the control channel of the NR MBMS may also be referred to as an NR MCCH (i.e. the first MCCH).

Further, the first MCCH is used to carry the first signaling, and in the embodiment of the present application, the name of the first signaling is not limited, for example, the first signaling is signaling a, where the first signaling includes configuration information of at least one first MTCH, where the first MTCH is a traffic channel (also referred to as a data channel or a transport channel) of an MBMS service, and the first MTCH is used to transport MBMS service data (such as service data of NR MBMS). In other words, the first MCCH is used to configure configuration information of a traffic channel of the NR MBMS, alternatively, the traffic channel of the NR MBMS may also be called as NR MTCH (i.e., the first MTCH).

Specifically, the first signaling is used for configuring a service channel of the NR MBMS, service information corresponding to the service channel, and scheduling information corresponding to the service channel. Further optionally, the service information corresponding to the service channel, for example, TMGI, session id, and other identification information for identifying the service. Scheduling information corresponding to the service channel, for example, RNTI used when MBMS service data corresponding to the service channel is scheduled, for example, G-RNTI, DRX configuration information, and the like.

The transmissions of the first MCCH and the first MTCH are scheduled based on the PDCCH. The RNTI used for scheduling the PDCCH of the first MCCH uses a unique network identifier, i.e. a fixed value. The RNTI used for scheduling PDCCH use of the first MTCH is configured through the first MCCH.

It should be noted that, in the embodiment of the present application, the naming of the first SIB, the first MCCH and the first MTCH is not limited. For convenience of description, the first SIB may also be simply referred to as SIB, the first MCCH may also be simply referred to as MCCH, and the first MTCH may also be simply referred to as MTCH, and referring to fig. 4, a PDCCH (i.e. MCCH PDCCH) for scheduling the MCCH and a notification PDCCH are configured through the SIB, where a PDSCH (i.e. MCCH PDSCH) for transmitting the MCCH is scheduled through DCI carried in MCCH PDCCH. Further, M PDCCHs for scheduling MTCH (i.e., MTCH 1PDCCH, MTCH 2PDCCH, & gt, MTCH M PDCCH) are configured through the MCCH, wherein DCI carried by MTCH n PDCCH schedules PDSCH for transmitting MTCH n (i.e., MTCH n PDSCH), n being an integer greater than or equal to 1 and less than or equal to M. Referring to fig. 5, MCCH and MTCH are mapped onto DL-SCH, and further, DL-SCH is mapped onto PDSCH, wherein MCCH and MTCH belong to a logical channel, DL-SCH belongs to a transport channel, and PDSCH belongs to a physical channel.

By the technical scheme of the embodiment of the application, the MBMS configuration information (namely, the configuration information of the first SIB, the configuration information of the first MCCH and the configuration information of the first MTCH) in the NR is defined, so that the NR system can support the broadcasting and the multicasting of the MBMS service. Furthermore, in order to achieve the purpose of improving service continuity and shortening service interruption time delay or losing service data by how the terminal device obtains MBMS configuration information before and after cell change, the following scheme is provided. It should be noted that, in the embodiment of the present application, the first SIB, the first MCCH, the first signaling, and the first MTCH belong to related concepts of the first cell side, and the second SIB, the second MCCH, the second signaling, and the second MTCH belong to related concepts of the second cell side. Wherein "first" and "second" are for distinguishing between two different cells, the concepts are similar.

Scheme one

Considering that the terminal device receives the MBMS service in one cell, when a cell change occurs, for service continuity and shortening service interruption or service delay or avoiding service data loss. The first SIB may be configured to take any one of the following transmission forms:

(1) The first SIB is continuously transmitted, in particular, the first SIB is continuously transmitted by a first cell to the terminal device.

Here, the first cell is a cell in which the terminal device is currently camping, and specifically, the first cell continuously (or always) transmits the first SIB without being based on the UE request. After the terminal equipment resides in the first cell, the terminal equipment can avoid sending a request message for requesting the first SIB, directly obtain the first SIB sent by the first cell, ensure service continuity, shorten service interruption or service delay or avoid service data loss.

(2) The first SIB is of a type of an area-specific SIB, and is associated with a first area identification, and the first area identification is used for identifying an effective area range of the first SIB.

The terminal equipment receives a first SIB sent by a first cell; after the terminal equipment changes from the first cell to a second cell, acquiring a first area identifier of the second cell side; if the first area identifier of the second cell side is the same as the first area identifier of the first cell side, the terminal device uses the acquired first SIB of the first cell to determine configuration information of the first MCCH, and receives an MBMS service based on the configuration information of the first MCCH.

Specifically, the first SIB is defined as an area specific (area specific) type SIB. Optionally, the first SIB may be configured in SIB1 as an area specific SIB, and a first area identifier associated with the first SIB is configured, where the first area identifier is used to identify a valid area range of the first SIB. Further, the first area identification may be a system information area identification (systemInformationAreaID) supported in the NR system or a newly defined area identification. It should be understood that the first area identifier may also be used to identify an MBMS service area, where the MBMS configuration information (i.e. the first SIB) remains unchanged, so that when a cell change occurs in the MBMS service area, the terminal device does not need to re-acquire the MBMS configuration information, and only needs to use the MBMS configuration information before use.

(3) The first SIB further includes configuration information of a second MCCH, where the second MCCH is configured to carry second signaling, and the second signaling is configured to determine configuration information of at least one second MTCH; the configuration information of the first MCCH corresponds to a first cell, the configuration information of the second MCCH corresponds to a second cell, and the second cell is a neighboring cell of the first cell.

The terminal equipment receives a first SIB sent by a first cell; after the terminal equipment changes from the first cell to the second cell, the acquired first SIB of the first cell is used for determining the configuration information of the second MCCH, and the MBMS service is received based on the configuration information of the second MCCH.

Specifically, for the first cell in which the terminal device is located, the first cell broadcasts not only the configuration information of the MCCH of the own cell (i.e., the configuration information of the first MCCH) but also the configuration information of the MCCH of the neighboring cell (i.e., the configuration information of the second MCCH), that is, the content carried in the first SIB includes the configuration information of the first MCCH corresponding to the first cell and the configuration information of the second MCCH corresponding to the second cell. After the cell change, the terminal device does not need to read the content in the first SIB of the second cell again.

The embodiments (1), (2) and (3) may be implemented alone or in any combination thereof.

Scheme II

Because the first SIB is sent through PDCCH scheduling, in order to enable the terminal device to acquire the content of the first SIB as soon as possible, to shorten service interruption or service delay or avoid service data loss, the following scheme is proposed.

(1) The first SIB is associated with an independent first common search space, the first common search space is used for transmitting a first PDCCH, and the first PDCCH is used for scheduling the first SIB.

In particular, a separate common search space (i.e. the first common search space) may be configured for the first SIB, optionally with a short period. The separate first common search space may be configured in SIB1 or in MIB.

(2) The first SIB is associated with a second public search space of the RMSI, the second public search space is used for transmitting a first PDCCH and a second PDCCH, the first PDCCH is used for scheduling the first SIB, and the second PDCCH is used for scheduling the RMSI; the first PDCCH carries first indication information, the first indication information is used for indicating that the data scheduled by the first PDCCH is the first SIB, the second PDCCH carries second indication information, and the second indication information is used for indicating that the data scheduled by the second PDCCH is the RMSI.

Specifically, a first SIB is defined using a common search space of RMSI (i.e., the second common search space). In this case, in order to distinguish the first SIB and the RMSI, first indication information is added in a first PDCCH for scheduling the first SIB, and the first PDCCH is indicated to schedule data as the first SIB by the first indication information; and similarly, adding second indication information into a second PDCCH for scheduling the RMSI, and indicating the data scheduled by the second PDCCH as the RMSI through the second indication information.

The first indication information and the second indication information may be collectively referred to as indication information, where the indication information is used to indicate whether the PDCCH scheduled data is RMSI, first SIB, or OSI.

(3) The first SIB is associated with an independent first SI-RNTI, the first SI-RNTI is used for scrambling a first PDCCH, and the first PDCCH is used for scheduling the first SIB.

Specifically, an independent SI-RNTI (i.e., the first SI-RNTI) is configured for a first SIB, which may be represented by an M-SI-RNTI, which is different from a network-wide unique SI-RNTI defined by an existing system, through which a first PDCCH for scheduling the first SIB is scrambled.

The schemes (1), (2) and (3) may be implemented alone, or the scheme (3) may be implemented in any combination with the scheme (1) or (2).

Scheme III

The first MCCH is scheduled through a third PDCCH, and the third PDCCH is scrambled through an SC-RNTI or an M-RNTI. Here, the transmission of the first MCCH is scheduled based on a PDCCH (i.e., the third PDCCH), and the RNTI adopted by the PDCCH is an RNTI uniquely allocated to the whole network, which may be represented by an SC-RNTI or an M-RNTI.

In this embodiment, it is defined that a first signaling carried in a first MCCH is valid within a range of a region, and specifically, the first MCCH is associated with a second region identifier, where the second region identifier is used to determine a valid range of the first signaling carried in the first MCCH.

Optionally, the second area identifier is a new definition identifier, and the new definition identifier is configured through the first SIB or the second SIB; or, the second area identifier is a system broadcast area identifier. Here, the second SIB is SIB1, for example. The system broadcast area identification is, for example, systemInformationAreaID in NR.

The terminal equipment receives a first SIB sent by a first cell; after the terminal equipment changes from the first cell to a second cell, acquiring a second area identifier of the second cell side; if the second area identifier of the second cell side is the same as the second area identifier of the first cell side, the terminal device uses the acquired first signaling in the first MCCH of the first cell to determine configuration information of at least one first MTCH, and receives an MBMS service based on the configuration information of the at least one first MTCH.

For example: when the terminal equipment changes from the cell, the second area identifier (such as systeminformationanareaid) of the second cell is firstly acquired, if the second area identifier is the same as the second area identifier of the first cell, the terminal equipment does not need to reacquire the content of the first signaling in the first MCCH, otherwise, the terminal equipment needs to reacquire, and then the MBMS service can be received.

Scheme IV

The first SIB further includes configuration information of at least one second MTCH; the configuration information of the first MTCH corresponds to a first cell, the configuration information of the second MTCH corresponds to a second cell, and the second cell is a neighboring cell of the first cell.

The terminal equipment receives a first SIB sent by a first cell; after the terminal equipment changes from the first cell to the second cell, the acquired first SIB of the first cell is used for determining the configuration information of the at least one second MTCH, and the MBMS service is received based on the configuration information of the at least one second MTCH.
