The terminal device in the embodiments of the present application can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a 5G network, or a terminal device in a future evolved public land mobile communication network (PLMN), etc.

[0069] It should be understood that this application does not limit the specific form of the terminal device.

[0070] The network device in the embodiment of the present application can be any device with wireless transceiver functions. The device includes but is not limited to: an evolved node B (eNB), a radio network controller (RNC), a node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., home evolved node B, or homenode B, HNB), a baseband unit (BBU), an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc. It can also be a gNB or transmission point (TRP or TP) in a 5G (such as NR) system, or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or transmission point, such as a baseband unit (BBU) or a distributed unit (DU).

[0071] In some deployments, a gNB may include a centralized unit (CU) and a DU. The gNB may also include an active antenna unit (AAU). The CU implements some gNB functions, while the DU implements some gNB functions. For example, the CU is responsible for processing non-real-time protocols and services, and implementing the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU is responsible for processing physical layer protocols and real-time services, and implementing the functions of the radio link control (RLC), media access control (MAC), and physical (PHY) layers. The AAU implements some physical layer processing functions, RF processing, and active antenna-related functions. Because RRC layer information ultimately becomes PHY layer information, or is converted from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling, can also be considered to be sent by the DU, or by both the DU and the AAU. It is understood that a network device can be a device that includes one or more of a CU node, a DU node, or an AAU node. In addition, the CU may be divided into a network device in an access network (radio access network, RAN), or may be divided into a network device in a core network (core network, CN), which is not limited in this application.

[0072] The network equipment manages one or more cells and provides services for the managed cells. The terminal device communicates with the cell through the transmission resources (for example, frequency domain resources, or spectrum resources) allocated by the network equipment. The cell can belong to a macro base station (for example, macro eNB or macro gNB, etc.) or a base station corresponding to a small cell. The small cells here can include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0073] The application provides a communication method. A terminal device acquires related information of a first service of a neighbor cell (may be referred to as a target cell) in a serving cell (may be referred to as a source cell), so that after the terminal device moves to the target cell, the terminal device can determine a manner of acquiring the first service in the target cell according to the related information of the first service of the target cell provided by the source cell, such as receiving data of the first service in the target cell according to configuration information corresponding to the first service in the source cell, or receiving data of the first service according to configuration information corresponding to the first service in the target cell included in the related information, or receiving configuration information of the first service in the target cell, and then receiving data of the first service provided by the target cell, so that the terminal device can reduce a time delay of acquiring service data.

[0074] It should be noted that the cell in which the terminal device resides can be referred to as a current cell or a serving cell. When the terminal device resides in the source cell, the source cell can be referred to as the current cell or the serving cell. When the terminal device moves to the coverage range of the target cell, the target cell can be referred to as the current cell or the serving cell.

[0075] The communication method provided by the embodiment of the application will be described in detail below with reference to the accompanying drawings.

[0076] Figure 2 FIG. 1 is a schematic flowchart of the communication method provided by the embodiment of the application.

[0077] In S210, the terminal device receives first information in the first cell, and the first information includes first indication information and / or second configuration information.

[0078] The first cell is a serving cell or a current cell of the terminal device. The first information is sent by a network device managing the first cell. The first indication information is used to indicate that the second configuration information is the same as or different from the first configuration information. The first configuration information is configuration information corresponding to a first service provided by the first cell, and the second configuration information is configuration information corresponding to the first service provided by a second cell. The second cell is a neighbor cell of the first cell.

[0079] The first cell provides a first service, and the network device that manages the first cell sends the configuration information corresponding to the first service to the terminal device in the first cell, that is, the first configuration information. The terminal device can receive the data of the first service provided by the first cell in the first cell according to the first configuration information. The second cell can also provide the first service, and the network device that manages the second cell (which can be the same as or different from the network device that manages the first cell) sends the configuration information corresponding to the first service to the terminal device in the second cell, that is, the second configuration information. In the embodiment of the present application, the terminal device receives the first information from the first cell, and the terminal device determines whether the first configuration information is the same or different from the second configuration information based on the first indication information in the first information, and / or, the second configuration information in the first information, the terminal device obtains the configuration information corresponding to the first service in the second cell through the first information received from the first cell within the coverage range of the first cell. In other words, even if the terminal device does not enter the coverage range of the neighboring cell, it can obtain the relevant information of the first service in the neighboring cell, so that after the terminal device moves from the coverage range of the first cell to the coverage range of the second cell, it can receive the data of the first service provided by the second cell according to the first information.

[0080] In this application, the first service provided by a cell can be understood as the first service currently being provided or the first service that can be provided. The configuration information corresponding to the first service provided by a cell can be understood as the configuration information corresponding to the first service currently being provided by the cell or the configuration information corresponding to the first service that can be provided by the cell.

[0081] In one implementation, the first information includes first indication information, and the first indication information indicates that the first configuration information is the same as the second configuration information.

[0082] The network device notifies the terminal device through the first indication information that the first configuration information is the same as the second configuration information. The terminal device determines that the first configuration information is the same as the second configuration information based on the first indication information. If the terminal device moves from the coverage area of ​​the first cell to the coverage area of ​​the second cell, the terminal device can receive data of the first service provided by the second cell based on the first configuration information received in the first cell.

[0083] In another implementation, the first information includes first indication information, the first indication information indicates that the first configuration information is different from the second configuration information, and the first information includes the second configuration information.

[0084] When the first configuration information is different from the second configuration information, the network device notifies the terminal device that the first configuration information is different from the second configuration information through the first indication information, and can notify the terminal device of the second configuration information corresponding to the first service in the first information. If the terminal device moves from the coverage of the first cell to the coverage of the second cell, the terminal device can receive data of the first service provided by the second cell according to the second configuration information acquired in the first cell.

[0085] In another implementation, the first indication information indicates that the first configuration information is different from the second configuration information, and the first information does not include the second configuration information.

[0086] When the first configuration information is different from the second configuration information, the network device notifies the terminal device that the first configuration information is different from the second configuration information through the first indication information, and the first information does not include the second configuration information. The terminal device determines that the second configuration information needs to be received in the second cell according to the first information, and receives data of the first service according to the second configuration information.

[0087] In another implementation, the first indication information indicates that the first configuration information is different from the second configuration information, and the first information includes the second configuration information.

[0088] The network device sends the terminal device the second configuration information corresponding to the first service provided by the second cell, and the terminal device can receive data of the first service provided by the second cell according to the second configuration information acquired in the first cell.

[0089] As an example and non-limiting, the first service is an MBS, and specifically can be an MBS using a single cell (SC) point to multipoint (PTM) transmission mode.

[0090] Optionally, the first information can be carried in transmission channel information corresponding to the first service provided by the first cell and sent by the network device.

[0091] Optionally, the configuration information corresponding to the configuration information of the first task can be one or more of the following:

[0092] A group-radio network temporary identity (G-RNTI) corresponding to the first service, scheduling information of a control channel (CCH) of the first service, or scheduling information of a transport channel (TCH) of the first service.

[0093] In a specific implementation, the first indication information may include but is not limited to the following two indication methods:

[0094] In a first manner, the first indication information includes a bit string, and the bit string is used to indicate whether configuration information corresponding to the first service provided by one or more neighboring cells of the first cell is the same as or different from the first configuration information.

[0095] Optionally, the first indication information includes a first bit string, one bit in the first bit string corresponds to one or more neighboring cells of the first cell, and one bit is used to indicate that the configuration information corresponding to the first service provided by the corresponding one or more neighboring cells is the same as or different from the first configuration information.

[0096] In one embodiment, control channel information corresponding to a first service provided by a first cell indicates Q first neighboring cells. Each bit in the first bit string corresponds to one or more first neighboring cells, where Q is an integer greater than or equal to 0. Optionally, the Q neighboring cells may be cells providing a single-cell point-to-multipoint service.

[0097] In another embodiment, the transmission channel information corresponding to the first service provided by the first cell includes second information, where the second information indicates M neighboring cells among the Q first neighboring cells that provide the first service. A bit in the first bit string corresponds to one or more of the M neighboring cells, where M is an integer less than or equal to N and greater than or equal to 0. Optionally, the Q neighboring cells may be cells providing single-cell point-to-multipoint MBS.

[0098] Optionally, one bit in the first bit string corresponds to a neighbor cell, optionally, the number of bits in the first bit string is equal to the number Q of first neighbor cells, or the number of bits in the first bit string is equal to the number M of M neighbor cells indicated by the second information.

[0099] For example, the first bit string includes 5 bits, one bit corresponds to a neighboring cell, and each bit is used to indicate whether the configuration information corresponding to the first service provided by a neighboring cell is the same as or different from the first configuration information. One bit among the 5 bits corresponds to the second cell, and is used to indicate that the second configuration information is the same as or different from the first configuration information. For example, the configuration information of the first service may be the G-RNTI corresponding to the MBS. If the 1 bit corresponding to the second cell is set to "1", it indicates that the G-RNTI corresponding to the MBS in the first cell is the same as the G-RNTI corresponding to the MBS in the second cell, and if it is set to "0", it indicates that they are different. Or conversely, if the 1 bit corresponding to the second cell is set to "1", it indicates that the G-RNTI corresponding to the MBS in the first cell is different from the G-RNTI corresponding to the MBS in the second cell, and if it is set to "0", it indicates that they are the same. For example, the first indication information can be expressed as

[0100] g-RNTI-neighbourCell BIT STRING(P),

[0101] Among them, g-RNTI-neighbourCell indicates that the first indication information indicates that the G-RNTI of the MBS provided by the neighboring cells of the first cell is the same or different, BIT STRING is the first bit string, and P represents the number of bits contained in the first bit string. Optionally, P can be equal to the number Q of the first neighboring cells. Optionally, the number Q can be expressed as SIZE (maxNeighCell-SCPTM), that is, the number of cells supporting single-cell point-to-multipoint. In this case, P can be replaced by SIZE (maxNeighCell-SCPTM), that is, the first indication information can be expressed as

[0102] g-RNTI-neighbourCell BIT STRING(SIZE(maxNeighCell-SCPTM)),

[0103] Optionally, P may be equal to the number M of M neighbor cells indicated by the second information. Optionally, M may be expressed as SIZE (maxNeighCell-SCPTMSupport), that is, the number of M neighbor cells supporting the first service. In this case, P may be replaced with SIZE (maxNeighCell-SCPTMSupport), that is, the first indication information may be expressed as

[0104] g-RNTI-neighbourCell BIT STRING(SIZE(maxNeighCell-SCPTMSupport)).

[0105] For another example, if the first service is MBS, the configuration information of the MBS includes the G-RNTI corresponding to the MBS, the scheduling information of the transmission channel, and the scheduling information of the control channel. Each configuration information in the MBS configuration information can be indicated using this embodiment, that is, each configuration information in the MBS configuration information corresponds to a bit string, which is used to indicate whether the configuration information of a neighboring cell is the same as or different from the configuration information in the first configuration information, wherein the bit string corresponding to each configuration information includes 1 bit corresponding to the second cell. The indication information can be expressed as follows

[0106] g-RNTI-neighbourCell BIT STRING(P),

[0107] sc-mcch-neighbourCellscheduling BIT STRING(P),

[0108] sc-mtch-neighbourCellscheduling BIT STRING(P),

[0109] Among them, g-RNTI-neighbourCell is used to indicate that the G-RNTI of the MBS provided by the neighboring cell is the same as or different from the G-RNTI in the first configuration information, sc-mcch-neighbourCellscheduling is used to indicate that the scheduling information of the control channel corresponding to the MBS provided by the neighboring cell of the first cell is the same as or different from the scheduling information of the control channel in the first configuration information, and sc-mtch-neighbourCellscheduling is used to indicate that the scheduling information of the transmission channel corresponding to the MBS provided by the neighboring cell of the first cell is the same as or different from the scheduling information of the transmission channel in the first configuration information. Optionally, the number P of bit strings can be equal to the number Q of the first cell, in which case P can be replaced by SIZE (maxNeighCell-SCPTM), or the number P can be equal to the number M of M neighboring cells indicated by the second information, in which case P can be replaced by SIZE (maxNeighCell-SCPTMSupport). If P=10, the 4th bit in the bit string corresponding to each item of configuration information in the MBS configuration information corresponds to the second cell, and being set to "1" indicates that it is the same as the item of configuration information in the first configuration information, and being set to "0" indicates that it is different from the item of configuration information in the first configuration information. If the 4th bit in the bit string corresponding to the G-RNTI is set to "0", the 4th bit in the bit string corresponding to the scheduling information of the transmission channel is set to "1", and the 4th bit in the bit string corresponding to the scheduling information of the transmission channel is set to "1", it means that the G-RNTI corresponding to the MBS provided by the second cell is different from the G-RNTI corresponding to the MBS provided by the first cell, and the scheduling information of the control channel and the scheduling information of the transmission channel corresponding to the MBS provided by the second cell are respectively the same as the scheduling information of the control channel and the scheduling information of the transmission channel in the first cell, but the present application is not limited to this.

[0110] For another example, the first service is an MBS, and the configuration information of the MBS includes the G-RNTI corresponding to the MBS, scheduling information of the transmission channel, and scheduling information of the control channel. The bit position "1" in the first bit string corresponding to the second cell indicates that each item of information in the configuration information of the MBS in the first cell is the same as each item of information in the configuration information of the MBS in the second cell, that is, the G-RNTI of the MBS, the scheduling information of the transmission channel, and the scheduling information of the control information are the same in the first cell and the second cell; the bit position "0" indicates that each item of information in the configuration information of the MBS in the first cell is different from each item of information in the configuration information of the MBS in the second cell, or the bit position "0" indicates that at least one item of the configuration information of the MBS in the first cell is different from the information in the configuration information of the MBS, but the present application is not limited thereto.

[0111] Optionally, one bit in the first bit string corresponds to one or more neighboring cells of the first cell, the neighboring cells of the first cell are grouped, one bit in the first bit string corresponds to a group of cells, and the number of bits in the first bit string is the same as the number of groups into which the neighboring cells are grouped.

[0112] In one implementation, the Q first neighbor cells are divided into one or more groups of cells, one bit in the first bit string corresponds to one of the groups of cells, and the number of bits in the first bit string is less than or equal to Q.

[0113] In another embodiment, the M neighboring cells indicated by the second information are divided into one or more groups of cells, one bit in the first bit string corresponds to one of the groups of cells, and the number of bits in the first bit string is less than or equal to M.

[0114] For example, one bit in the first bit string corresponds to a group of neighboring cells. Setting the bit to "1" indicates that the configuration information of the first service provided by the group of cells corresponding to the bit is the same as the first configuration information; setting the bit to "0" indicates that the configuration information of the first service provided by the group of cells corresponding to the bit is different from the first configuration information, or setting the bit to "0" indicates that the configuration information of the first service provided by at least one cell in the group of cells corresponding to the bit is different from the first configuration information. If the first bit string includes 3 bits, each bit corresponds to a group of cells, where the second cell belongs to the group of cells corresponding to the first bit, if the 3 bits are represented as "101", and the first bit is set to "1", it means that the configuration information corresponding to the first service provided by the group of cells to which the second cell belongs is the same as the first configuration information, but the present application is not limited to this.

[0115] For another example, a bit in a first bit string corresponds to a group of neighboring cells of a first cell, the first service is MBS, and the configuration information includes a G-RNTI, scheduling information for transport channels, and scheduling information for control channels. A bit in the first bit string is used to indicate that each item of information in the configuration information corresponding to the MBS provided by the group of cells corresponding to the bit is identical to each item of information in the first configuration information, or that at least one item of information in the configuration information corresponding to the MBS provided by the group of cells corresponding to the bit is different from the corresponding information in the first configuration information. For example, if the first bit string includes four bits, each bit corresponding to a group of cells, and a second cell belongs to the group of cells corresponding to the second bit, if the four bits are represented as "1001," and the second bit is set to "0," it indicates that at least one item of information in the G-RNTI, scheduling information for transport channels, and scheduling information for control channels corresponding to the MBS provided by the group of cells to which the second cell belongs is different from the corresponding information in the first configuration information. For example, if the G-RNTI for the MBS provided by one of the cells in the group of cells to which the second cell belongs is different from the G-RNTI in the first configuration information, then the bit corresponding to the cell group is "0." The fourth bit in the first bit string is set to "1", indicating that the G-RNTI, transmission channel scheduling information, and control channel scheduling information corresponding to the MBS provided by a group of cells corresponding to the fourth bit are the same as the G-RNTI, transmission channel scheduling information, and control channel scheduling information in the first configuration information.

[0116] For another example, a bit in the first bit string corresponds to a group of neighboring cells of the first cell, the first service is MBS, and the configuration information includes G-RNTI, scheduling information of the transmission channel, scheduling information of the control channel, etc. Each item of configuration information corresponds to a bit string, and each item of configuration information corresponds to a bit in a bit string, which is used to indicate whether the configuration information corresponding to the MBS provided by a group of cells corresponding to the bit is the same as or different from the configuration information in the first configuration information. The bit string corresponding to each item of configuration information includes 4 bits, used to indicate whether the configuration information of 4 groups of cells is the same or different from the configuration information in the first configuration information, wherein the second cell belongs to a group of cells corresponding to the third bit of the 4 bits, such as the 4 bits corresponding to G-RNTI are "0000", wherein the third bit is set to "0", indicating that the G-RNTI corresponding to the MBS provided by a group of cells to which the second cell belongs is different from the G-RNTI in the first configuration information; the 4 bits corresponding to the scheduling information of the transmission channel are "1010", wherein the third bit is set to "1", indicating that the scheduling information of the control channel corresponding to the MBS provided by a group of cells to which the second cell belongs is the same as the scheduling information of the control channel in the first configuration information; and, the 4 bits corresponding to the scheduling information of the control channel are "1000", wherein the third bit is set to "0", indicating that the scheduling information of the transmission channel corresponding to the MBS provided by a group of cells to which the second cell belongs is different from the scheduling information of the transmission channel in the first configuration information, but the present application is not limited to this.

[0117] Optionally, the configuration information corresponding to the first service includes N sub-configuration information, the first indication information includes a second bit string, the second bit string includes at least one bit field, a bit field in the second bit string corresponds to one or more neighboring cells of the first cell, and a bit in a bit field is used to indicate whether the first sub-configuration information in the one or more neighboring cells corresponding to the bit field where the bit is located is the same as or different from the first sub-configuration information in the first cell. The first sub-configuration information is one of the N sub-configuration information.

[0118] In one implementation, a bit field in the second bit string corresponds to one or more of the above-mentioned first neighboring cells.

[0119] In another implementation, a bit field in the second bit string corresponds to one or more neighbor cells among the M neighbor cells providing the first service indicated by the second information.

[0120] For example, the first service is MBS, and the configuration information for the MBS is the scheduling information for the transmission channel. The scheduling information for the transmission channel includes three sub-configuration information: duration sub-configuration information, discontinuous reception inactive state sub-configuration information, and scheduling start offset sub-configuration information. The second bit string includes two bit fields, each corresponding to one or more neighboring cells. A bit field includes three bits, and these three bits correspond one-to-one with the three sub-configuration information. If the second bit string is "110 001", where the first three bits are a bit field and the second three bits are a bit field, the second cell corresponds to the first bit field, i.e., the first three bits. The three bits in this bit field correspond, in sequence, to the duration sub-configuration information, the discontinuous reception inactive state sub-configuration information, and the scheduling start offset sub-configuration information. The bit field "110" indicates that the duration sub-configuration information in the transmission channel scheduling information corresponding to the MBS provided by the second cell is the same as the duration sub-configuration information in the first configuration information, the inactive state sub-configuration information of the discontinuous reception is the same as the inactive state sub-configuration information of the discontinuous reception in the first configuration information, and the scheduling start offset sub-configuration information is different from the scheduling start offset sub-configuration information in the first configuration information, but the present application is not limited thereto. The first indication information may be represented as follows

[0121] sc-mtch-neighbourCellscheduling BIT STRING(N*P),

[0122] Wherein, N is the number of sub-configuration information, “*” represents multiplication, and optionally, P may be equal to the number Q of the first neighbor cells or P may be equal to the number M of the M neighbor cells indicated by the second information, or P may be equal to the number of groups of neighbor cells.

[0123] For another example, the configuration information includes three items of configuration information: G-RNTI, transmission channel scheduling information, and control channel scheduling information. The transmission channel scheduling information also includes time sub-configuration information, discontinuous reception inactive state sub-configuration information, and scheduling start offset sub-configuration information. The G-RNTI and control channel scheduling information can be indicated by the first bit string, and the transmission channel scheduling information can be indicated by the second bit string. The indication information can be represented as follows:

[0124] g-RNTI-neighbourCell BIT STRING(P),

[0125] sc-mcch-neighbourCellscheduling BIT STRING(P),

[0126] sc-mtch-neighbourCellscheduling BIT STRING(N*P),

[0127] The length of the bit string corresponding to the G-RNTI and the length of the bit string corresponding to the scheduling information of the control channel are P, and one bit in the bit string is used to indicate whether the configuration information of the corresponding neighboring cell is the same as or different from the configuration information of the first configuration information. Optionally, P can be equal to the number Q of the first neighboring cells or P can be equal to the number M of M neighboring cells indicated by the second information, or P can be equal to the number of groups of neighboring cells. The length of the bit string corresponding to the scheduling information of the transmission channel is N*P, and one bit in the bit string is used to indicate whether the corresponding sub-configuration information in the corresponding neighboring cell is the same as or different from the corresponding sub-configuration information in the first configuration information, but the present application is not limited to this.

[0128] In a second approach, the transmission channel information corresponding to the first service provided by the first cell includes neighbor cell information of the first service, wherein the neighbor cell information includes second cell information, and the first indication information is carried in the second cell information.

[0129] For example, if the first service is MBS, the transmission channel information of MBS can be written as SC-MTCH-Info, which can be expressed as follows:

[0130] SC-MTCH-Info::=SEQUENCE{

[0131] sc-mtch-neighbourCell SC-MTCH-NeighbourCellInfoList

[0132] },

[0133] Among them, SC-MTCH-Info includes a neighbor cell information list SC-MTCH-NeighbourCellInfoList, and the neighbor cell list includes one or more neighbor cell information (which can be written as SC-MTCH-NeighbourCellInfo). For example, the number of neighbor cell information in the neighbor cell list can be equal to the number M of M neighbor cells indicated by the second information, and a neighbor cell information is the information of one neighbor cell among the M neighbor cells. It should be noted that the transmission channel information may also include other information not listed in this example, such as the first configuration information, which is not limited in this application.

[0134] Exemplarily, the configuration information of the first service includes configuration information of a G-RNTI. The first indication information in the second cell information can represent whether the G-RNTI of the first service provided by the second cell is the same as or different from the G-RNTI in the first configuration information by enumerating "yes" or "no", and the second cell information can be represented as follows

[0135] SC-MTCH-NeighbourCellInfo ::= SEQUENCE {

[0136] g-rnti-indication ENUMERATED {true, false}

[0137] },

[0138] wherein the g-rnti-indication is used to indicate whether the G-RNTI of the first service provided by the second cell is the same as or different from the G-RNTI in the first configuration information. Alternatively, the first indication information in the second cell information can be a Boolean value indicating "yes" or "no" to represent whether the G-RNTI of the first service provided by the second cell is the same as or different from the G-RNTI in the first configuration information, and the second cell information can be represented as follows,

[0139] SC-MTCH-NeighbourCellInfo ::= SEQUENCE {

[0140] g-rnti-indication BOOLEAN

[0141] },

[0142] Further alternatively, the first indication information can be 1 bit, and "1" indicates that the G-RNTI of the first service provided by the second cell is the same as or different from the G-RNTI in the first configuration information, or "0" indicates that the G-RNTI of the first service provided by the second cell is different from the G-RNTI in the first configuration information. Or vice versa, "1" indicates different, and "0" indicates the same, which is not limited in the present application.

[0143] For another example, the configuration information of the first service includes three configuration information items: G-RNTI, scheduling information of the transmission channel, and scheduling information of the control channel. When the first indication information in the second cell information is the same, it means that each item of the configuration information corresponding to the first service provided by the second cell is the same as each item in the first configuration information. When the first indication information in the second cell information is different, it means that each item of the configuration information corresponding to the first service provided by the second cell is different from each item in the first configuration information. Alternatively, each item of configuration information in the configuration information of the first service corresponds to an indication information, which is used to indicate whether the indication information is the same as or different from the indication information in the first configuration information. For example, the second cell information can be represented as follows

[0144]

[0145] Among them, sc-mcch-neighbourCellscheduling is used to indicate whether the scheduling information of the control channel corresponding to the provided first service is the same as or different from the scheduling information of the control channel in the first configuration information. sc-mtch-neighbourCellscheduling is used to indicate whether the scheduling information of the transmission channel corresponding to the provided first service is the same as or different from the scheduling information of the transmission channel in the first configuration information.

[0146] Optionally, the configuration information corresponding to the first service includes N sub-configuration information, and the first indication information also includes N sub-indication information, the N sub-indication information corresponds to the N sub-configuration information, and one of the sub-indication information is used to indicate whether the first sub-configuration information in the second cell is the same as or different from the first sub-configuration information in the first cell, wherein the first sub-configuration information is one of the N sub-configuration information.

[0147] For example, the first service is MBS, and the configuration information of the MBS is scheduling information of a transmission channel. The scheduling information of the transmission channel includes three sub-configuration information, namely, duration sub-configuration information (which can be written as onDurationTimerSCPTM), discontinuous reception (DRX) inactivity state sub-configuration information (which can be written as drx-InactivityTimerSCPTM), and scheduling start offset sub-configuration information (which can be written as schedulingPeriodStartOffsetSCPTM). The first indication information in the second cell information includes three indication information, respectively indicating whether the three sub-configuration information of the first service provided by the second cell is the same as or different from the three sub-configuration information in the first configuration information. For example, the second cell information can be represented as follows, but the present application is not limited thereto.

[0148]

[0149] or,

[0150]

[0151]

[0152] For another example, the configuration information includes three items of configuration information: the G-RNTI, scheduling information for the transmission channel, and scheduling information for the control channel. The scheduling information for the transmission channel also includes time sub-configuration information, discontinuous reception inactive state sub-configuration information, scheduling start offset sub-configuration information, and the like. The G-RNTI and transmission channel scheduling information corresponding to the first service provided by the second cell can be indicated by indication information as being the same as or different from the corresponding configuration information in the first configuration information. The indication information corresponding to the transmission channel scheduling information can include three sub-indication information, each indicating whether the sub-configuration information is the same as or different from the corresponding sub-configuration information in the first configuration information. For example, the second cell information can be represented as follows, but the present application is not limited thereto.

[0153]

[0154] or,

[0155]

[0156] It should be noted that the names and representations of the above-mentioned first indication information and sub-indication information are only examples, and each information may also include other information, which is not limited in this application.

[0157] In the embodiments of the present application, MBS is often used as an example for description. The first service may be other services, and the present application is not limited thereto.

[0158] S220, the terminal device moves from the coverage range of the first cell to the mobility range of the second cell.

[0159] The first cell and the second cell may be different cells managed by the same network device, or may be different cells managed by different network devices, and this application does not limit this.

[0160] S230, the terminal device receives data of the first service provided by the second cell according to the first information.

[0161] In one embodiment, after receiving the first information at S210, the terminal device can determine whether the second configuration information is the same as or different from the first configuration information based on the first indication information in the first information. If the second configuration information is the same as the first configuration information, the terminal device receives the data of the first service provided by the second cell based on the first configuration information at S230; if the second configuration information is different from the first configuration information and the first information includes the second configuration information, the terminal device receives the data of the first service provided by the second cell based on the second configuration information in the first information; if the second configuration information is different from the first configuration information and the first information does not include the second configuration information, the terminal device receives the second configuration information sent by the network device that manages the second cell at S230, and receives the data of the first service based on the second configuration information.

[0162] In another embodiment, after receiving the first information at S210, the terminal device determines, based on whether the first information includes the second configuration information, a method for receiving the data of the first service provided by the second cell at S230. If the first information includes the second configuration information, the terminal device receives the data of the first service provided by the second cell at S230 based on the second configuration information in the first information. If the first information does not include the second configuration information, the terminal device first receives the second configuration information sent by the network device that manages the second cell at S230, and then receives the data of the first service provided by the second cell based on the second configuration information.

[0163] According to the above scheme, the terminal device obtains the relevant information of the first service of the neighboring cell in the serving cell (which may be called the source cell), so that after the terminal device moves to the neighboring cell (which may be called the target cell), it can determine the method of obtaining the first service in the target cell based on the relevant information of the first service of the target cell provided by the source cell, such as receiving the data of the first service in the target cell according to the configuration information corresponding to the first service provided by the source cell, or receiving the data of the first service according to the configuration information corresponding to the first service provided by the target cell included in the relevant information, or receiving the configuration information of the first service in the target cell, and then receiving the data of the first service provided by the target cell, which can reduce the delay of the terminal device in obtaining service data.
