In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

With the pursuit of speed, latency, high-speed mobility, energy efficiency and the diversity and complexity of the services in future life, the third generation partnership project (3)^rdGeneration Partnership Project, 3GPP) the international organization for standardization began developing 5G. The main application scenarios of 5G are: enhanced Mobile Ultra wide band (eMBB), Low-Latency high-reliability communication (URLLC), and massive Machine-Type communication (mMTC).

On the one hand, the eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., and the difference between the capabilities and the requirements is relatively large, it cannot be said that it must be analyzed in detail in conjunction with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety, and the like. Typical characteristics of mtc include: high connection density, small data volume, insensitive time delay service, low cost and long service life of the module, etc.

RRC state

In order to reduce air interface signaling, quickly recover wireless connection, and quickly recover data service, 5G defines a new Radio Resource Control (RRC) state, that is, an RRC INACTIVE (RRC _ INACTIVE) state. This state is distinguished from the RRC IDLE (RRC IDLE) state and the RRC ACTIVE (RRC ACTIVE) state. Wherein the content of the first and second substances,

1) RRC _ IDLE state (IDLE state for short): mobility is UE-based cell selection reselection, paging is initiated by a Core Network (CN), and a paging area is 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 there is a UE context on the base station side and the UE side. The network side knows that the location of the UE is at a specific cell level. Mobility is network side controlled mobility. Unicast data may be transmitted between the UE and the base station.

3) RRC _ INACTIVE state (INACTIVE state for short): mobility is UE-based cell selection reselection, there is a connection between CN-NRs, UE context exists on a certain base station, paging is triggered by RAN, RAN-based paging area is managed by RAN, and network side knows that UE location is based on RAN's paging area level.

MBMS

The 3GPP Release 6(Release 6, R6) introduced MBMS, a technology for transmitting data from one data source to a plurality of UEs through shared network resources, which provides multimedia services while efficiently utilizing the network resources to implement broadcast and multicast of higher-rate (e.g., 256kbps) multimedia services.

Since the MBMS spectrum efficiency in 3GPP R6 is low, it is not enough to effectively carry and support the operation of mobile tv type services. Therefore, in LTE, 3GPP explicitly proposes to enhance the support capability for downlink high-speed MBMS services, and determines the design requirements for the physical layer and air interface.

The 3GPP R9 introduces evolved MBMS (eMBMS) into LTE. eMBMS proposes a Single Frequency Network (SFN) concept, that is, a Multimedia Broadcast multicast service Single Frequency Network (MBSFN), where MBSFN employs a uniform Frequency to simultaneously transmit service data in all cells, but needs to ensure synchronization between the cells. The method can greatly improve the distribution of the overall signal-to-noise ratio 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 protocol.

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 the idle-state or connected-state UE.

The 3GPP R13 introduces a Single Cell Point To multipoint (SC-PTM) concept, and SC-PTM is based on the MBMS network architecture.

MBMS introduces new logical channels including a Single Cell-Multicast Control Channel (SC-MCCH) and a Single Cell-Multicast Transport Channel (SC-MTCH). The SC-MCCH and SC-MTCH are mapped to a Downlink-Shared Channel (DL-SCH), and the DL-SCH is further mapped to a 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 (HARQ) operation.

MBMS introduces a new System Information Block (SIB) type, SIB 20. Specifically, the configuration information of the SC-MCCH is transmitted through 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, and the scheduling of the wireless frame and the subframe of the SC-MCCH. Further, 1) the boundary of the modification period of the SC-MCCH satisfies SFN mod m ═ 0, where SFN represents the system frame number of the boundary, and m is the modification period of the SC-MCCH (i.e., SC-MCCH-modification period) configured in SIB 20. 2) And scheduling the radio frame of the SC-MCCH to meet the following requirements: SFN mod MCCH-repetition period ═ MCCH-Offset, where SFN represents the system frame number of a radio frame, MCCH-repetition period represents the repetition period of SC-MCCH, and MCCH-Offset represents the Offset of SC-MCCH. 3) The sub-frame of the SC-MCCH is scheduled and indicated by SC-MCCH-Subframe.

The SC-MCCH is scheduled through a Physical Downlink Control Channel (PDCCH). On one hand, a new Radio Network Temporary Identity (RNTI), that is, a Single Cell RNTI (SC-RNTI) is introduced to identify a PDCCH (e.g., SC-MCCH PDCCH) for scheduling an SC-MCCH, and optionally, the SC-RNTI is fixedly valued as FFFC. On the other hand, a new RNTI, namely a 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, and optionally, the SC-N-RNTI is fixedly valued as FFFB; further, the change notification may be indicated by one bit of 8 bits (bits) of the DCI 1C. In LTE, the configuration information of SC-PTM is based on SC-MCCH configured by SIB20, and then SC-MCCH configures SC-MTCH which is used for transmitting service data.

Specifically, the SC-MCCH transmits only one message (i.e., SCPTMConfiguration) for configuring configuration information of the SC-PTM. The configuration information of SC-PTM includes: temporary Mobile Group Identity (TMGI), session Identity (session id), Group RNTI (G-RNTI), Discontinuous Reception (DRX) configuration information, SC-PTM service information of the neighbor cell, and the like. It should be noted that SC-PTM in R13 does not support Robust Header Compression (ROHC) function.

The downlink discontinuous reception of SC-PTMs is controlled by the following parameters: ondurationTimerSCPTM, drx-InactivetTimeSCPTM, SC-MTCH-SchedulingCycle, and SC-MTCH-SchedulingOffset.

When [ (SFN x 10) + subframe number ] module (SC-MTCH-scheduling cycle) ═ SC-MTCH-scheduling offset is satisfied, starting a timer onDurationTimerSCPTM;

when receiving downlink PDCCH dispatching, starting a timer drx-InactivetyTimerSCPTM;

the downlink SC-PTM service is received only when the timer onDurationTimerSCPTM or drx-inactivityttimerscptm is running.

SC-PTM service continuity adopts the MBMS service continuity concept based on SIB15, namely, SIB15+ MBMSIntestrIndication. The traffic continuity of idle UEs is based on the concept of frequency priority.

In NR, many scenarios need to support multicast and broadcast traffic needs, such as in car networking, industrial internet, etc. It is necessary to introduce MBMS in NR. It is clear how to configure the MBMS configuration information in the NR to implement and optimize the MBMS service. On the other hand, in LTE, MBMS configuration information is implemented by configuring an SC-MCCH through SIB20, and then configuring an SC-MTCH through the SC-MCCH; the transmission of the SC-MCCH is based on the cell level, the MBMS configuration information needs to be acquired again after the cell of the UE is changed, and service interruption or service delay caused by the cell change is introduced. Furthermore, since the SIB in NR is transmitted based on the UE request, service interruption or service delay is further introduced after the cell change. Therefore, the following technical scheme of the embodiment of the application is provided.

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

step 201: the method comprises the steps that terminal equipment receives a first SIB, wherein the first SIB comprises configuration information of a first MCCH, the first MCCH is used for carrying first signaling, and the first signaling is used for determining the configuration information of at least one first MTCH.

In the embodiment of the application, the network device sends the first SIB, and the terminal device receives the first SIB. Optionally, the network device may be a base station, for example, a gbb.

In this embodiment of the present application, a new SIB (referred to as a first SIB) is defined, and referring to fig. 3, 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, and optionally, 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 a first signaling, and in this embodiment of the present application, the name of the first signaling is not limited, for example, the first signaling is signaling a, 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 transmit MBMS service data (e.g., 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, which may also be called NR MTCH (i.e., the first MTCH) optionally.

Specifically, the first signaling is used to configure 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, the identification information for identifying the service, such as the TMGI, the session id, and the like. The scheduling information corresponding to the traffic channel, for example, the RNTI used when the MBMS service data corresponding to the traffic channel is scheduled, for example, G-RNTI, DRX configuration information, and the like.

It should be noted that the transmission of the first MCCH and the first MTCH is scheduled based on the PDCCH. Wherein, the RNTI used by the PDCCH for scheduling the first MCCH uses a network-wide unique identifier, which is a fixed value. The RNTI used by the PDCCH for scheduling the first MTCH is configured through the first MCCH.

It should be noted that, in the embodiment of the present application, 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 abbreviated as SIB, the first MCCH may also be abbreviated as MCCH, and the first MTCH may also be abbreviated as MTCH, and referring to fig. 4, a PDCCH (i.e., MCCH PDCCH) for scheduling MCCH and a notification PDCCH are configured through SIB, wherein a PDSCH (i.e., MCCH PDSCH) for transmitting MCCH is scheduled through DCI carried by MCCH PDCCH. Further, M PDCCHs (i.e., MTCH 1PDCCH, MTCH 2PDCCH, …, MTCH M PDCCH) for scheduling MTCH are configured through the MCCH, wherein DCI carried by the MTCH n PDCCH schedules a PDSCH (i.e., MTCH n PDSCH) for transmitting MTCH n, n being an integer of 1 or more and M or less. Referring to fig. 5, MCCH and MTCH are mapped to DL-SCH, which belong to a logical channel, DL-SCH which belongs to a transport channel, and PDSCH which belongs to a physical channel, and further DL-SCH which is mapped to PDSCH.

Through the technical scheme of the embodiment of the application, the MBMS configuration information in NR (namely the configuration information of the first SIB, the first MCCH and the first MTCH) is made clear, so that the NR system supports the broadcast and multicast of the MBMS service. Further, in order to achieve how the terminal device acquires the MBMS configuration information before and after the cell change, so as to achieve the purposes of improving service continuity and shortening service interruption delay or service data loss, the following scheme is proposed. 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 a related concept on the first cell side, and the second SIB, the second MCCH, the second signaling, and the second MTCH belong to a related concept on the second cell side. Where "first" and "second" are used to distinguish between two different cells, the concepts are similar.

Scheme one

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

(1) the first SIB is continuously transmitted, and specifically, the first SIB is continuously transmitted to the terminal device by a first cell.

Here, the first cell is a cell in which the terminal device currently camps, and specifically, the first cell does not continuously (or always) transmit the first SIB based on the UE request. After the terminal device resides in the first cell, the terminal device can avoid sending a request message for requesting the first SIB, and directly obtain the first SIB sent by the first cell, thereby ensuring service continuity, and shortening service interruption or service delay or avoiding service data loss.

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

The terminal equipment receives a first SIB sent by a first cell; after the terminal equipment is changed 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 determines the configuration information of the first MCCH using the acquired first SIB of the first cell, 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 SIB1 may be configured with a first SIB being an area specific type SIB, and configure a first area identifier associated with the first SIB, 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 (systemlnformationareaid) 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, and the MBMS configuration information (i.e. the first SIB) remains unchanged in the MBMS service area, so that when the terminal device changes the cell in the MBMS service area, the terminal device does not need to re-acquire the MBMS configuration information, and may use the previous MBMS configuration information.

(3) The first SIB further comprises configuration information of a second MCCH, wherein the second MCCH is used for carrying second signaling, and the second signaling is used for determining the 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; and after the terminal equipment is changed from the first cell to a second cell, determining the configuration information of the second MCCH by using the acquired first SIB of the first cell, and receiving the MBMS service based on the configuration information of the second MCCH.

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

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

Scheme two

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

(1) The first SIB is associated with an independent first common search space for transmitting a first PDCCH, the first PDCCH being 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 periodicity. The independent first common search space may be configured in the SIB1 or in the MIB.

(2) The first SIB is associated with a second common search space of the RMSI, the second common 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.

In particular, the first SIB is defined to use the common search space of the RMSI (i.e., the second common search space). In this case, in order to distinguish the first SIB from the RMSI, first indication information is added to a first PDCCH for scheduling the first SIB, and the first indication information indicates that data scheduled by the first PDCCH is the first SIB; similarly, second indication information is added in a second PDCCH for scheduling RMSI, and the second indication information indicates that data scheduled by the second PDCCH is the RMSI.

It should be noted that the first indication information and the second indication information may be collectively referred to as indication information, and the indication information is used to indicate whether data scheduled by the PDCCH 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, a separate SI-RNTI (i.e. the first SI-RNTI) is configured for the first SIB, which may be represented by an M-SI-RNTI, which is different from an existing system-defined network-wide unique SI-RNTI, by which the first PDCCH for scheduling the first SIB is scrambled.

The means (1), (2) and (3) may be implemented alone, or the means (3) may be implemented in arbitrary combination with the means (1) or (2).

Scheme three

And the first MCCH is scheduled through a third PDCCH, and the third PDCCH is scrambled through SC-RNTI or M-RNTI. Here, the transmission of the first MCCH is scheduled based on the PDCCH (i.e. the third PDCCH) which uses RNTI which is a RNTI uniquely allocated throughout the network and may be denoted by SC-RNTI or M-RNTI.

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

Optionally, the second region 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, for example, SIB 1. The system broadcast area identification is, for example, systemlnformationareaid in NR.

The terminal equipment receives a first SIB sent by a first cell; after the terminal equipment is changed from the first cell to a second cell, acquiring a second area identifier of the second cell side; and 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 equipment determines the configuration information of at least one first MTCH by using the acquired first signaling in the first MCCH of the first cell, and receives the MBMS based on the configuration information of the at least one first MTCH.

For example: when the terminal device changes from the cell, first, a second area identifier (such as systemlnformationareaid) of the second cell is acquired, if the second area identifier is the same as the second area identifier of the first cell, the terminal device does not need to acquire the content of the first signaling in the first MCCH again, otherwise, the terminal device needs to acquire again, and then the terminal device can receive the MBMS service.

Scheme four

The first SIB further comprises 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 a 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.

For example: for a first cell where a terminal device is located, the first cell not only broadcasts configuration information of an MCCH of the cell (i.e., configuration information of the first MCCH), but also broadcasts configuration information of an MTCH of a neighboring cell (i.e., configuration information of the second MTCH), and when the terminal device is changed in cell, it is not necessary to re-read content carried in the second MCCH of the second cell.

Fig. 6 is a schematic structural diagram of an information configuration apparatus provided in an embodiment of the present application, which is applied to a terminal device, and as shown in fig. 6, the information configuration apparatus includes:

a receiving unit 601, configured to receive a first SIB, where the first SIB includes configuration information of a first MCCH, and 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.
