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.
At early deployment of NRs, full NR coverage is difficult to acquire, so typical network coverage is wide area LTE coverage and island coverage mode of NRs. And a large amount of LTE is deployed below 6GHz, and the frequency spectrum below 6GHz which can be used for 5G is few. NR must study spectral applications above 6GHz while high-band coverage is limited and signal fading is fast. Meanwhile, in order to protect the mobile operators from early investment in LTE, a working mode of tight coupling (tight interworking) between LTE and NR is proposed.
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 is a technology for transmitting data from one data source to a plurality of terminal equipments through a shared network resource, which can effectively utilize the network resource while providing a multimedia service, and realize broadcasting and multicasting of a multimedia service of a higher rate (e.g., 256 kbps).
Due to the low MBMS spectrum efficiency, 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 terminal devices 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 the terminal device in idle state is based on the concept of frequency priority.
In the technical solution of the embodiment of the present application, a new SIB (referred to as a first SIB) is defined, 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 a PDCCH (i.e. MCCH PDCCH) for scheduling the MCCH and a notification PDCCH are configured through 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 1 PDCCH, MTCH 2 PDCCH, …, 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. The MCCH and the MTCH are mapped to the DL-SCH, and further, the DL-SCH is mapped to the PDSCH, wherein the MCCH and the MTCH belong to a logical channel, the DL-SCH belongs to a transport channel, and the PDSCH belongs to a physical channel.
It should be noted that, the MBMS service in the above scheme includes, but is not limited to, a multicast service and a multicast service. The embodiment of the application is described by taking an MBS service as an example, and the description of the "MBS service" may be replaced by a "multicast service" or an "MBMS service".
In the NR MBS, as shown in fig. 2, a 5G core network transfers MBS traffic To a 5G access network (such as a gNB) through a shared GTP tunnel, and the 5G access network may determine To transfer MBS traffic To a terminal device in a Point-To-Point (PTP) manner or in a Point-To-multipoint (Point To Multipoint, PTM) manner.
For terminal devices receiving MBS services, other non-MBS services, such as an eMBB service, are also received. The terminal device can be released to an idle state or an inactive state or kept in a connected state by the network side when there is no MBS service transmission. When the terminal equipment is in idle state or inactive state, the network side can wake up the terminal equipment by paging to receive MBS service when the data of the MBS service arrives.
In NR, paging of multiple users corresponding to the same Paging Occasion (PO) may be multiplexed in one Paging message, so that multiple users corresponding to one PO may monitor Paging messages of MBS service, and even if some users do not participate in the MBS service, paging messages of MBS service may wake up those users, which may affect those users, for example, cause electricity consumption of those users. In addition, NR supports beam scanning (beam scanning) transmission, so that one paging message may be transmitted in multiple copies in one cell, the specific copy depends on the number of synchronization signal blocks (Synchronization Signal Block, SSB) actually transmitted in the cell, and thus, the paging message of MBS service may have a high load, and radio resources are wasted. Based on this, the embodiments herein contemplate narrowing the paging area of MBS services, which is beneficial both for network radio resource savings and for power savings for other users not participating in MBS services.
Fig. 3 is a flow chart of a method for managing MBS services according to an embodiment of the present application, as shown in fig. 3, where the method for managing MBS services includes the following steps:
step 301: the network equipment sends RRC release information to the terminal equipment, the terminal equipment receives the RRC release information sent by the network equipment, the RRC release information is used for triggering the terminal equipment to enter an idle state or an inactive state, wherein the RRC release information carries first indication information, and the first indication information is used for indicating whether MBS business is in a suspension state or a release state.
In the embodiment of the application, the network device may be a base station, such as a gNB. For the terminal device configured with a certain MBS service, if the MBS service has no data transmission, but the MBS service is not released, the network device may release the terminal device into an idle state or an inactive state or maintain in a connected state. When the terminal equipment enters an idle state or a non-activated state, when the data of the MBS service is reached, the network side pages the terminal equipment in a specific paging area, thereby waking up the terminal equipment to receive the MBS service. When the terminal equipment enters a connection state, when the MBS service data is reached, the network side can send the MBS service data to the terminal equipment.
It should be noted that, the MBS service is not released, which is shown in that the GTP tunnel from the core network to the access network corresponding to the MBS service is not released.
In the embodiment of the present application, the network side pages the terminal device in a specific paging area, so as to avoid the influence of paging on the terminal device that is not in MBS service (i.e. the terminal device that does not participate in the MBS service), the following scheme may be implemented.
Scheme one: limiting RRC state after MBS service deactivation
Specifically, for the terminal device configured with the MBS service, the MBS service is not released, but there is no data transmission of the MBS service for a while, and the terminal device is limited to be unable to enter the idle state.
Here, in the idle state, paging is triggered by the core network, and the paging area is a TA list (TA list) managed by the core network. In the inactive state, paging is triggered by the access network and the paging area is a radio access network management area (RAN Notification Area, RNA) managed by the core network. Since the range of the TA list is too large, sending a paging message in the paging area affects a larger number of terminal devices, and thus limits the terminal devices from entering an idle state.
In this embodiment, limiting that the terminal device cannot enter the idle state includes: the network side triggers the terminal equipment to enter an inactive state or maintains the terminal equipment in a connection state through the RRC release message.
In this embodiment of the present application, the RRC release message carries first indication information, where the first indication information is used to indicate whether the specified MBS service is in a suspension state or a release state. For example: the first indication information is 1 bit indication information, the value of 1 bit indication information is 1 to indicate that MBS service is in suspension state, and the value of 1 bit indication information is 0 to indicate that MBS service is in release state; or, a value of 0 for the 1-bit indication information indicates that the MBS service is in a suspension state, and a value of 1 for the 1-bit indication information indicates that the MBS service is in a release state.
In an alternative manner, the RRC release message further carries a service identifier of the MBS service. Further, the service identification includes at least one of: G-RNTI, TMGI, MBS session identification.
In an optional manner, when the first indication information indicates that the MBS service is in a suspension state, the network side may instruct the terminal device to store the service identifier of the MBS service, so as to provide a basis for subsequent MBS signaling monitoring of the MBS service. Specifically, 1) the RRC release message further carries second indication information, where the second indication information is used to instruct the terminal device to save a service identifier of the MBS service; or 2) the first indication information is further used for indicating the terminal equipment to save the service identifier of the MBS service.
Scheme II: limiting the range of paging areas to MBS paging areas
Specifically, for the terminal device configured with the MBS service, the MBS service is not released, but only temporarily has no data transmission of the MBS service, and the network side may trigger the terminal device to enter an idle state or an inactive state or be maintained in a connected state through an RRC release message.
In this embodiment of the present application, the RRC release message further carries third indication information, where the third indication information is used to indicate an MBS paging area, and the MBS paging area is used to determine a paging range of the terminal device. Here, for the idle state, the MBS paging area is smaller than the TA list, so that the influence of paging on the terminal equipment not for the MBS service (i.e., the terminal equipment not participating in the MBS service) can be avoided. For the inactive state, the MBS paging zone may be the same as or different from the RNA, further alternatively, the MBS paging zone is smaller than the RNA. The implementation of the MBS paging zone is described below in connection with different RRC states.
A) The RRC release message is used for triggering the terminal equipment to enter an idle state, and the first indication information carried in the RRC release message is used for indicating a first MBS paging area.
Here, for a terminal device in an idle state, the terminal device performs a cell reselection behavior in the first MBS paging zone; and under the condition that the terminal equipment moves out of the first MBS paging area, reporting a position update request message to the network equipment, and receiving a position update response message sent by the network equipment, wherein the position update response message is used for determining an updated MBS paging area.
In an alternative manner, the terminal device sends first configuration information to the network device, the network device receives the first configuration information sent by the terminal device, where the first configuration information is used to determine an MBS paging area suggested by the terminal device, and the terminal device suggested MBS paging area is used by the network device to determine the first MBS paging area, where the first MBS paging area is the same as or different from the MBS paging area suggested by the terminal device.
In an alternative manner, the first MBS paging zone is managed by a core network element. Here, the core network element is, for example, an AMF.
In this embodiment of the present application, the granularity of configuration of the first MBS paging zone may be of per UE, that is, the first MBS paging zone is an MBS paging zone for the terminal device. Alternatively, the granularity of the configuration of the first MBS paging zone may be per MBS service (or per MBS session), i.e. the first MBS paging zone is an MBS paging zone for the MBS service.
In one example, the first MBS paging zone is per UE, and for the terminal equipment released to the idle state, the RRC release message carries the third indication information to indicate the first MBS paging zone, where the terminal equipment does not need to report to the network side when performing cell reselection in the first MBS paging zone, but needs to report a location update request message to the network side when the terminal equipment moves out of the first MBS paging zone, so as to implement location update. Optionally, the terminal device may send configuration information of the paging area suggested by the terminal device to the network side, and the network side decides the first MBS paging area according to the configuration information and configures the first MBS paging area to the terminal device. The first MBS paging zone may be maintained (i.e., managed) at the AMF or maintained at the base station.
In one example, the first MBS paging zone is per MBS session, and for the terminal equipment released to the idle state, the RRC release message carries the third indication information to indicate the first MBS paging zone, where the terminal equipment does not need to report to the network side when performing cell reselection in the first MBS paging zone, but needs to report a location update request message to the network side when the terminal equipment moves out of the first MBS paging zone, so as to implement location update. Optionally, the terminal device may send configuration information of the paging area suggested by the terminal device to the network side, and the network side decides the first MBS paging area according to the configuration information and configures the first MBS paging area to the terminal device. The first MBS paging zone may be maintained (i.e., managed) at the AMF.
In the above scheme, for the case where the first MBS paging zone is a per UE, different terminal equipments are each configured with an independent first MBS paging zone, for example: UE1 is configured with MBS paging zone 1 and UE2 is configured with MBS paging zone 2. After the terminal equipment moves out of the first MBS paging area, updating the MBS paging area.
In the above scheme, for the case where the first MBS paging zone is per MBS session, different MBS services (i.e., MBS sessions) are configured with separate first MBS paging zones, for example: MBS service 1 is configured with MBS paging zone 1 and MBS service 2 is configured with MBS paging zone 2. After the terminal equipment moves out of the first MBS paging area, updating the own MBS paging area, wherein the updated MBS paging area is also suitable for other terminal equipment of the MBS service, so that the updated MBS paging area of other terminal equipment except the terminal equipment in a multicast group corresponding to the MBS service is determined based on first MBS signaling, and the scheduling information of the first MBS signaling is scrambled by G-RNTI corresponding to the MBS service.
Specifically, for updating the first MBS paging area of other terminal equipments in the multicast group of the MBS service, the network side updates the first MBS paging area through the MBS signaling scheduled by the G-RNTI corresponding to the MBS service. When the terminal equipment enters an idle state, at least storing service identifiers (such as G-RNTI and TMGI) of MBS service, thereby receiving MBS signaling by utilizing the service identifiers of the MBS service and updating the first MBS paging area.
B) The RRC release message is used for triggering the terminal equipment to enter a non-activated state, and the first indication information carried in the RRC release message is used for indicating a second MBS paging area.
Here, for a terminal device in an inactive state, the terminal device performs a cell reselection behavior in the second MBS paging zone; and under the condition that the terminal equipment moves out of the second MBS paging area, reporting a position update request message to the network equipment, and receiving a position update response message sent by the network equipment, wherein the position update response message is used for determining an updated MBS paging area.
In an alternative manner, the second MBS paging zone is managed by an access network element. Here, the access network element is, for example, a gNB.
In this embodiment of the present application, the second MBS paging zone is the same as RNA; alternatively, the second MBS paging zone is different from RNA.
In the embodiment of the application, when the data of the MBS service reaches, the network side sends the paging message which is sent in the MBS paging area. Optionally, the AMF may also send an MBS paging zone of the multicast group of the MBS service to the base station.

For example: when establishing MBS service, the network configures MBS P-RNTI to the terminal equipment through the special signaling.
In this case, MBS P-RNTI used by different MBS services and/or different terminal equipments is different. For example: the MBS P-RNTI used by the same terminal equipment aiming at different MBS services is different. For example: different terminal devices use different MBS P-RNTIs for the same MBS service.
In the above scheme, the MBS paging message or the MBS wake-up PDCCH carries MBS wake-up indication information, where the MBS wake-up indication information is used to indicate wake-up MBS service. For example: the MBS awakening indication information carries a service identifier (such as TMGI) of a certain MBS service, thereby indicating to awaken the MBS service corresponding to the service identifier.
B) Here, the MBS paging search space (MBS paging search space) is a paging search space dedicated for MBS services. The embodiment of the application defines a MBS paging search space dedicated to receiving scheduling information of MBS paging messages (i.e., MSB paging DCI, which is used to carry the scheduling information of MBS paging messages, and is carried in MBS wake-up PDCCH).

For example: different terminal devices use the same MBS paging search space for the same MBS service.
In an alternative manner, the MBS paging search space is a paging search space for MBS services and terminal equipment (i.e., per MBS service+ue), and the MBS paging search space is configured through dedicated signaling or configured through RRC release messages. For example: when establishing MBS service, the network configures MBS paging search space to the terminal equipment through the special signaling.
In this case, MBS paging search spaces used by different MBS services and/or different terminal equipments are different. For example: the same terminal equipment has different MBS paging search spaces aiming at different MBS services. For example: different terminal devices use different MBS paging search spaces for the same MBS service.
The terminal equipment monitors MBS paging DCI in the configured MBS paging search space, wherein the MBS paging DCI carries scheduling information of paging information.
C) Here, the MBS paging occasion is a paging occasion dedicated to the MBS service, and the network side may reserve or configure a dedicated (or independent) paging occasion for the MBS service from the current candidate paging occasions, which is specially used for receiving the scheduling information of the MBS paging message.
In an alternative manner, the MBS paging occasion is a paging occasion for a cell (i.e., per cell), and the MBS paging occasion is configured by system broadcast information.
For this case, MBS paging occasions used by different cells are different.

For example: the same terminal equipment has different MBS paging occasions aiming at different MBS services. For example: different terminal devices use different MBS paging occasions aiming at the same MBS service.
And the terminal equipment monitors the MBS paging message in the configured MBS paging occasion.
According to the technical scheme, MBS paging and traditional paging are isolated, or the scheme of reducing the paging area at the RAN side is provided, so that the influence of MBS paging on other terminal equipment is reduced, the air interface signaling load can be reduced, and the purpose of saving electricity of the terminal equipment can be achieved.
