In order to more clearly explain the technical solution according to the embodiment of the present disclosure, the following will be described in detail in conjunction with drawings and specific embodiments.

In order to more clearly explain the technical solution according to the embodiment of the present disclosure, the following will be described in detail in conjunction with drawings and specific embodiments.

Referring to Figure 1, Figure 1 is a network structure diagram to be applied to an embodiment of the present disclosure. As shown in FIG. 1, the network includes a plurality of terminals 11 and network-side devices 12, among which the terminal 11 may be a user equipment (UE) or other terminal equipment. Bar, e.g.: mobile phone, tablet personal computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), vehicle-mounted device or wearable device It may be a terminal-side device such as a (Wearable Device), and it should be explained that the specific type of terminal is not limited in the embodiments of the present disclosure. Direct communication (or referred to as direct communication) may be performed between the terminals 11 through a direct communication interface, and among them, the link of direct communication may be referred to as Sidelink (direct communication link or translated as side link), The interface corresponding to is referred to as a direct communication interface. Terminals of direct communication may be all on-network or all off-network, and some devices may be on-network and some devices may be off-network. On-network means that the device participating in direct communication is located within the communication carrier coverage range of the 3GPP base station, and off-network means that the device participating in direct communication is not located within the communication carrier coverage range of the 3GPP base station. The network device 12 may be a base station, such as a macro station, LTE eNB, 5G NR NB, etc.; The network device may also be a small station such as a Low Power Node (LPN), pico, femto, or the like, or the network device may be an access point (AP); The base station may be a network node jointly configured with a central unit (CU) and a plurality of distributed units (DUs) managed and controlled by the central unit. It should be noted that the embodiments of the present disclosure do not limit specific types of network-side devices.

Referring to Figure 2, Figure 2 is a flow chart of a cell selection method provided by an embodiment of the present disclosure, as shown in Figure 2, the method,

Step 201: A step in which a terminal receives a broadcast message transmitted by a network device, wherein the broadcast message determines whether the network device supports inter-radio access technology (RAT) deployment, and the inter-RAT supported by the network device is deployed. a receiving step for indicating at least one of a resource location arranged by one mode and an inter-RAT supported by the network device; and

Step 202: the mobile station performing cell selection according to the broadcast message, wherein the cell selection is initial cell selection or cell reselection; includes

Among them, step 201 may be a step of receiving a broadcast message transmitted by one or more network devices, and the broadcast message of each network device determines whether each network device supports inter-RAT deployment, and the supported inter-RAT is deployed. This is to indicate at least one of a resource location arranged by one mode and supported inter-RAT.

What needs to be explained is that whether the network device supports inter-RAT deployment can be understood by whether the cell corresponding to the network device supports inter-RAT deployment, and the inter-RAT-deployed mode supported by the network device, It can be understood as a mode arranged by an inter-RAT supported by a cell corresponding to a network device, and a resource location arranged by an inter-RAT supported by a network device is a resource location arranged by an inter-RAT supported by a cell corresponding to a network device. can be understood as

And, if the broadcast message indicates a mode arranged by the inter-RAT supported by the network device, it may default that the network device supports the arrangement of the inter-RAT, and in the broadcast message, the inter-RAT supported by the network device arranged When the resource location is indicated, it may default that the network device supports inter-RAT deployment.

In a selectable implementation manner, the above-described broadcast message includes at least one or more of the following fields,

Option 1: indication field indicating whether inter-RAT deployment is supported;

For example, the corresponding field is N bits, N is a positive integer greater than or equal to 1, specifically, it may be 1 bit, and a value of 0 indicates that it is not supported, and a value of 1 indicates that it is supported. indicate

Option 2: field indicating the resource distribution mode deployed by the inter-RAT;

For example, the corresponding field is M bits, M is a positive integer greater than or equal to 1, specifically, may be 2 bits, and a value of 11 indicates that all resource distribution modes are supported, and the value is In the case of 01 or 10, it indicates that only one resource distribution mode is supported, for example, 01 indicates that the terminal supports only the resource distribution mode selected by itself, and 10 indicates that only the resource distribution mode scheduled by the network is supported. If the value is 00, it indicates that the inter-RAT does not support the arrangement of any resource distribution mode, that is, does not support the arrangement of the inter-RAT.

Option 3: a field indicating the location of resources deployed by inter-RAT;

This field indicates the resource location of another RAT arranged by the inter-RAT. For example, the base station of NR indicates the location of LTE V2X resources (eg, allocation by a resource pool, etc.). If the field exists If so, it indicates that inter-RAT deployment is supported, and the specific supported distribution mode may specifically indicate or default that only the resource distribution mode selected by the terminal itself is supported, and the resource pool location related to the field has already been deployed. Therefore, if the field does not exist, it indicates that inter-RAT deployment is not supported, that is, it implicitly indicates that inter-RAT deployment is not supported.

It should be explained that the step of performing cell selection according to the broadcast message may be a step of performing cell selection by combining other information of the network device according to the broadcast message, for example, combining traffic supported by the network device. Alternatively, cell selection may be performed by combining information such as whether the network device supports inter-carrier deployment or not, among which, such information is transmitted by the network device to the terminal, or obtained by the terminal measuring , or may be pre-arranged, etc., but is not limited thereto. Of course, in some implementations, cell selection may be performed only according to the above-mentioned broadcast message, but is not limited thereto.

In an embodiment of the present disclosure, it is possible to realize that a network device transmits broadcasting information through the above-described steps, and the broadcasting information includes configuration of a RAT of the network device, a mode configured by an inter-RAT supported by the network device, and the Indicates at least one of the resource locations arranged by the inter-RAT supported by the network device. The terminal device receives the broadcast information transmitted by the network device, and selects a cell according to the broadcast information. In this way, it is possible to realize that the terminal selects a cell according to the RAT arrangement, and thus, the communication performance of the terminal can be improved by selecting a cell more suitable for the terminal's needs. In addition, in the NR system, in addition to supporting inter-carrier deployment, the network device can support inter-RAT deployment, and the traffic supported by the terminal is also richer, so the cell provided in the embodiment of the present disclosure The selection method can solve the problem of how the terminal proceeds with cell selection and/or reselection, and improves the communication performance of the terminal by enabling the terminal device to select an appropriate cell.

As a selectable implementation method, the step of the terminal performing cell selection according to the broadcast message,

performing, by the terminal, cell selection according to a cell priority level order according to the broadcast message; includes

Among them, the order of the above-mentioned cell priority levels may be prearranged, stipulated in the protocol, or arranged by the network side.

In the step of performing cell selection according to the cell priority level order according to the broadcast message, the terminal determines the cell type according to the above-described broadcast message, and selects each type of cell according to the above-described cell priority level order. This may be a step of determining a priority level.

Optionally, if the order of the cell priority levels includes a priority level in which a plurality of cells exist, the terminal selects a cell having the strongest signal strength from among the plurality of cells or randomly selects one cell. . That is, if a plurality of cells are included in the highest priority level among cells that can be selected by the terminal, the terminal selects a cell having the strongest signal strength among the plurality of cells or randomly selects one cell. Of course, in the embodiments of the present disclosure, without limitation, for example, the terminal may select itself, and the terminal may select one according to rules set by itself, that is, select a cell belonging to the terminal implementation.

Optionally, according to the order of the cell priority level, if there is no selectable cell, the terminal proceeds traffic using pre-arranged resources.

For example, if there is no selectable cell, the terminal recognizes that the terminal is in an off-network state, proceeds with V2X traffic using pre-arranged resources, and may specifically transmit the traffic, and the terminal is off Improve communication performance in network conditions.

It should be explained that a plurality of cells may be included in the above-described cell priority level order, but in a practical application, the number of cells that the UE can select may be less than the number of cells in the cell priority order, so the UE selects In the process, a cell having the highest priority level may be selected from among cells that the UE may select.

In the implementation method, by proceeding with cell selection according to the order of the above-described cell priority level, it is possible to improve the communication performance of the terminal by selecting a cell that more meets the needs of the terminal.

What needs to be explained is, in order to more clearly explain the technical solution according to the present disclosure, a Long Term Evolution (LTE) system and a New Radio (NR) system are taken as examples, and cell types are divided as follows can,

a) directly providing LTE V2X traffic, not providing inter-carrier placement, and not providing inter-RAT placement;

b) providing inter-carrier to deploy LTE V2X traffic, but not providing inter-RAT deployment;

c) directly providing LTE V2X traffic, not providing inter-carrier placement, but providing inter-RAT to deploy NR mode mode1 or mode2;

m) providing inter-RAT to deploy NR V2X traffic, and also providing inter-RAT to deploy NR mode1 or mode2;

n) providing an inter-RAT to deploy NR V2X traffic, and also providing an inter-RAT to deploy NR mode1 and mode2;

o) Deploying NR V2X traffic by providing inter-carrier, and deploying LTE mode3 or mode4 by providing inter-RAT; and

p) NR V2X traffic is deployed by providing inter-carriers, and LTE mode3 and mode4 are deployed by providing inter-RAT.

Among them, the aforementioned NR mode1 may be a network-scheduled resource distribution mode in direct communication of the NR system, and NR mode2 may be a resource distribution mode self-selected by a terminal in direct communication of the NR system; LTE mode3 may be a resource distribution mode scheduled by a network device in the LTE system, that is, the network allocates resources for the UE according to Sidelink Buffer Status Reporting (BSR) reported by the UE. a resource distribution mode that distributes; LTE mode4 may be a resource distribution mode selected by the terminal itself in the LTE system, that is, the terminal selects one of the transmission resources prearranged by itself or broadcasted by the network to transmit the sidelink.

It should be noted that the above-mentioned plurality of cells is just an example, and in a real application, the communication system does not support all types of cells described above, and since it is relatively difficult to support dynamic deployment by inter-RAT, For example, some cell types such as cell type d or h may not be supported.

Optionally, the cell priority level order includes a first cell priority level order or a second cell priority level order.

Among them, the above-described first cell priority level order or second cell priority level order may be selected by the terminal itself, or may be arranged by the network side, or may be arranged by itself.

Further, if the terminal only supports the traffic of the first system, the cell priority level sequence is the first cell priority level sequence; or,

If the current traffic of the terminal is the traffic of the first system, the cell priority level sequence is the first cell priority level sequence; or,

If the terminal supports the traffic of the first system and the traffic of the second system, the cell priority level order is the second cell priority level order; or,

If the current traffic of the terminal includes the traffic of the first system and the second system, the cell priority level order is the second cell priority level order.

In one scheme, the first system is a Long Term Evolution (LTE) system, and the second system is a New Radio (NR) system. In another scheme, the above-mentioned first system is a NR system, and the second system is an LTE system.

It should be explained that the above-mentioned first cell priority level order when the above-mentioned first system is an LTE system may be different from the above-mentioned first cell priority level order when the above-mentioned first system is a NR system. can

In addition, the above-described traffic is vehicle-to-everything (V2X) traffic. For example, the traffic of the first system may be referred to as LTE V2X traffic or NR V2X traffic, or the traffic of the second system It may be referred to as LTE V2X traffic or NR V2X traffic. It should be noted that the above traffic may also be traffic using other direct communication, and the present disclosure is not limited thereto.

the first cell is a cell providing traffic of the first system;

the second cell is a cell that provides an inter-carrier and arranges the traffic of the first system;

The third cell provides traffic of the second system, provides inter-RAT arrangement, and also provides inter-RAT to arrange a plurality of resource distribution modes of the first system; a cell is a cell that provides an inter-RAT to arrange traffic of the first system, and also provides an inter-RAT to arrange a plurality of resource distribution modes of the first system;

In an embodiment of the present disclosure, a terminal receives a broadcast message transmitted by a network device, and the broadcast message determines whether or not the network device supports deployment of an inter radio access technology (RAT), and an inter RAT supported by the network device. It is for indicating at least one of a mode arranged by the network device and a resource location arranged by an inter-RAT supported by the network device; The terminal performs cell selection according to the broadcast message, and the cell selection is an initial cell selection or a cell reselection. In this way, it is possible to realize that the terminal selects a cell according to the RAT arrangement, and thus, the communication performance of the terminal can be improved by selecting a cell more suitable for the terminal's needs.

Referring to FIG. 3, FIG. 3 is a flowchart of a method for transmitting a broadcast message provided by an embodiment of the present disclosure. As shown in FIG. 3, the method includes:

Step 301: A network device transmits a broadcast message to a terminal, wherein the broadcast message determines whether or not the network device supports inter-RAT deployment, and an inter-RAT-deployed mode supported by the network device. and a transmitting step for indicating at least one of resource locations arranged by an inter-RAT supported by the network device. includes

It should be explained that, in the embodiments of the present disclosure, the above-described terminals may be terminals according to any implementation manner of the method embodiments of the present disclosure, and any implementation manners of the terminals of the method embodiments of the present disclosure are all implementations of the present disclosure. It can be implemented by the above-mentioned terminal as an example, and can achieve the same technical effect, which will not be described in detail herein.

Referring to FIG. 4 , the method provided in the embodiments of the present disclosure will be described with the following three embodiments as an example.

Example 1:

In this embodiment, cell selection/reselection is performed in a situation where the terminal device supports only LTE V2X traffic.

As shown in FIG. 4, FIG. 4 is an exemplary flow diagram of an embodiment of the present disclosure, and descriptions of each step in the above-described flow chart are as follows,

Step 1: The network device transmits broadcast information (the terminal receives the broadcast message sent by the network device).

Specifically, the broadcast message includes at least one or more of the following fields,

Option 1: indication field indicating whether inter-RAT deployment is supported;

For example, the corresponding field is N bits, N is a positive integer greater than or equal to 1, specifically, it may be 1 bit, and a value of 0 indicates that it is not supported, and a value of 1 indicates that it is supported. indicate

Option 2: field indicating the resource distribution mode deployed by the inter-RAT;

For example, the corresponding field is M bits, M is a positive integer greater than or equal to 1, specifically, may be 2 bits, and a value of 11 indicates that all resource distribution modes are supported, and the value is In the case of 01 or 10, it indicates that only one resource distribution mode is supported, for example, 01 indicates that the terminal supports only the resource distribution mode selected by itself, and 10 indicates that only the resource distribution mode scheduled by the network is supported. If the value is 00, it indicates that the inter-RAT does not support the arrangement of any resource distribution mode, that is, does not support the arrangement of the inter-RAT.

Option 3: a field indicating the location of resources deployed by inter-RAT;

This field indicates the resource location of another RAT arranged by the inter-RAT. For example, the base station of NR indicates the location of LTE V2X resources (eg, allocation by a resource pool, etc.). If the field exists If so, it indicates that inter-RAT deployment is supported, and the specific supported distribution mode may specifically indicate or default that only the resource distribution mode selected by the terminal itself is supported, and the resource pool location related to the field has already been deployed. Therefore, if the field does not exist, it indicates that inter-RAT deployment is not supported, that is, it implicitly indicates that inter-RAT deployment is not supported.

Step 2: The terminal device performs cell selection according to the broadcast information.

The above steps are described in the following priority level sequence as an example, and other priority level sequences may refer to the corresponding description of the corresponding priority level sequence, which is not described in detail herein, and the priority level sequence silver,
