[0002] The future network may be divided into two layers: one layer is a wide coverage cell, which can work in low-frequency bands such as 700 MHz, providing continuous and more reliable coverage support to maintain good connectivity and mobility; the other layer is a high-rate cell, which can work in higher frequency bands with high bandwidth, such as 2.3 GHz, 3.5 GHz, millimeter wave, terahertz frequency and visible light.

[0120] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0121] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0122] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0123] See also Figure 1 , Figure 1 is a flow chart of the information processing method provided in the embodiment of the present application, such as Figure 1 As shown, the following steps are included:

[0124] Step 101: Obtain first information, where the first information is used to indicate a cell type of a neighboring cell.

[0125] The cell types include: a first type cell, which is used to provide continuous and reliable coverage layer support; and a second type cell, which is used to provide a high transmission rate.

[0126] The first type of cell is also called a wide coverage cell, which can provide high-quality mobile communication services and a wider coverage area. The second type of cell is also called a high-speed cell, which can provide a higher transmission rate and can be turned on on demand according to communication needs. The separation of wide coverage cells and high-speed cells aims to provide seamless global signaling access link coverage through low and medium frequency bands to solve mobility problems; and to provide greater capacity and higher rates by turning on millimeter waves, terahertz and visible light on demand in specific scenarios such as local and short-distance communications.

[0127] Among them, the method of the embodiment of the present application can be applied to a terminal or a network device, such as a base station.

[0128] like Figure 2The figure shows a schematic diagram of cell deployment. When a terminal moves in a wide coverage cell, if the terminal passes through a high-speed cell, the terminal should continue to reside in the wide coverage cell. A high-speed cell B is deployed at the junction of the low-frequency A wide coverage cell and the low-frequency C wide coverage cell. When the terminal moves in the wide coverage cell A area and passes through the visible light cell, terahertz cell, and high-frequency cell, the terminal signaling continues in the low-frequency A wide coverage cell, and other high-speed cells such as visible light cells, terahertz cells, and high-frequency cells provide data transmission in the form of carrier aggregation or dual links, thereby ensuring wide coverage of signaling and high-speed transmission of data. Similarly, the cells covered by the wide coverage cell C are treated the same as the wide coverage cell A.

[0129] To this end, when the terminal is in the overlapping coverage area of ​​a wide coverage cell and a high-rate cell (visible light cell or terahertz cell or high-frequency cell), it is necessary to ensure that the wide coverage cell is the main cell as much as possible. For the terminal, the terminal can obtain the first information from the network device. Among them, the first information is carried in a system message, such as SIB1 (System Information Block 1, system information block 1), MIB (Master Information Block, master information block), etc. Through the first information, the terminal can determine the cell type of the neighboring area, so as to determine whether to perform cell selection, reselection or switching, etc. For example, when the cell type is the first cell type, it is determined to perform cell selection, reselection or switching, etc., so as to ensure access to the cell of the first cell type as much as possible.

[0130] In the embodiment of the present application, a field or information element may be added to the system message, and the field or information element is used to indicate the cell type, including a first type cell (wide coverage) or a second type cell (high rate). This information can be used as one of the decision conditions for switching the target cell, or as one of the conditions for cell selection and reselection, so that the target cell tends to select a wide coverage cell, solves the mobility problem, and saves energy consumption.

[0131] For network equipment, as the terminal moves, the source base station needs to determine whether the target cell is a high-speed cell or a wide-coverage cell, thereby deciding which cell the terminal switches to.

[0132] Specifically, the network device may obtain the first information from a neighboring network device.

[0133] If an XN interface exists between network devices, the network device may send a first request to the neighboring network device through the XN interface, and receive a first response sent by the neighboring network device through the XN interface, wherein the first response includes the first information.

[0134] As shown in Figure 3(a) or Figure 3(b), the network device (base station 1) can send XN SETUP REQUEST or NG-RAN NODECONFIGURATION UPDATE and other signaling to the neighboring cell network device (neighboring cell base station 2) through the XN interface to obtain the cell type of the neighboring cell base station, which are high-rate cells and which are wide-coverage cells. The neighboring cell network device can send the first information to the network device through XN SETUPRESPONSE or NG-RAN NODE CONFIGURATION UPDATE ACKNOWLEDGE and other signaling.

[0135] For example, base station 1 may add IE information in signaling such as XN SETUP REQUEST or NG-RAN NODE CONFIGURATION UPDATE, as shown in Table 1. Base station 1 sends an XN SETUP REQUEST or NG-RAN NODE CONFIGURATION UPDATE message to neighboring base station 2 to obtain the cell types of neighboring base stations, which are high-rate cells and which are wide-coverage cells.

[0136] Table 1

[0137]

[0138] For example, neighboring cell base station 2 adds IE information in XN SETUP RESPONSE, NG-RAN NODE CONFIGURATION UPDATE ACKNOWLEDGE, etc., as shown in Table 2. Neighboring cell base station 2 sends messages such as XN SETUP RESPONSE and NG-RAN NODE CONFIGURATION UPDATE ACKNOWLEDGE to base station 1 to indicate the cell type.

[0139] Table 2

[0140]

[0141] If there is no XN interface between the network devices, the network device may send a first request to the neighboring network device via the NG interface, and receive a first response sent by the neighboring network device via the NG interface, wherein the first response includes the first information.

[0142] like Figure 4As shown, the network device (base station 1) can obtain the cell type of the neighboring base station (neighboring base station 2), which are high-speed cells and which are wide-coverage cells, by sending CELL TYPE REQUEST and other signaling to AMF (Access and Mobility Management Function). The neighboring network device can send CELL TYPE RESPONSE and other signaling to the network device through AMF, and carry the first information.

[0143] For example, the network device (base station 1) can add IE information in CELL TYPE REQUEST, which is sent by base station 1 to AMF, and then sent by AMF to neighboring base station 2, to obtain the cell type of neighboring base station 2, which are high-rate cells and which are wide-coverage cells. The information added in CELL TYPE REQUEST is shown in Table 1. Neighboring base station 2 adds IE information in CELL TYPE RESPONSE, which is sent by neighboring base station 2 to AMF, and then sent by AMF to base station 1 to transmit the cell type. The information added in CELL TYPE RESPONSE is shown in Table 2.

[0144] Step 102: Perform cell switching, selection or reselection according to the first information.

[0145] For the terminal, in this step, combined with Figure 5 , the terminal accesses. If the current serving cell is a first type cell, i.e., a wide coverage cell, the terminal accesses, otherwise the terminal will preferentially select the first type cell, i.e., a wide coverage cell for access, thereby ensuring that the serving cell currently accessed by the terminal is a wide coverage cell.

[0146] The terminal measures the service quality of the current serving cell (ie, the first type cell, a wide coverage cell), such as channel strength, signal quality or interference level.

[0147] In a case where the current serving cell of the terminal is a first type cell and the service quality of the current serving cell does not meet the cell switching, selection or reselection condition (for example, the service quality of the current serving cell is higher than the switching threshold of the current serving cell):

[0148] If it is determined according to the first information that the neighboring cell is a second type cell and the service quality of the second type cell is higher than that of the current serving cell, the second type cell is used as a secondary cell, that is, at this time, the change or switching of the primary cell may not be performed, and the second type cell is added as a secondary cell;

[0149] If it is determined according to the first information that the neighboring cell is a first type of cell and the service quality of the first type of cell is higher than that of the current service cell, the neighboring cell is used as the target cell for cell switching, selection or reselection, that is, when a wide-coverage cell with better signal quality is measured, a normal switching process or a primary or secondary cell change is performed.

[0150] In a case where the current serving cell of the terminal is a first type cell and the service quality of the current serving cell meets the cell switching, selection or reselection condition (for example, the service quality of the current serving cell is lower than or equal to the switching threshold of the current serving cell):

[0151] If it is determined according to the first information that the neighboring cell is a first type of cell, the neighboring cell and the current serving cell are in a hetero-frequency network (i.e., the neighboring cell is a hetero-frequency wide coverage cell), and the service quality of the neighboring cell is higher than that of the current serving cell, the neighboring cell is used as a target cell for performing cell switching or selection or reselection, that is, changing the primary cell or switching the wide coverage cell: changing the primary cell to a hetero-frequency wide coverage cell or switching to a hetero-frequency wide coverage cell;

[0152] If it is determined according to the first information that the neighboring area includes a first type of cell and a second type of cell, the neighboring area and the current service cell are in the same frequency network (that is, the neighboring area is a cell with wide coverage on the same frequency), and the service quality of the neighboring area is higher than that of the current service cell, after performing a cell switch or selecting or reselecting from the current service cell to the second type of cell, a cell switch or selecting or reselecting from the second type of cell to the first type of cell is performed, that is, the change between the main cell and the high-speed cell or the switching between the main cell and the high-speed cell is performed first, and then the switching and change between the high-speed cell and the cell with wide coverage on the same frequency is performed. In other cases, the normal cell change and switching process is performed.

[0153] For example, in conditional switching, the base station configures the switching conditions of the terminal, and the terminal performs switching when one or more switching execution conditions are met. In the scenario of multi-frequency networking, when the terminal performs switching, the terminal needs to decide the target cell for switching based on whether the cell is a high-rate cell or a wide-coverage cell. The terminal obtains that cell A is a wide-coverage cell by receiving messages such as SSB (SynchronizationSignal and PBCH block, synchronization signal / physical broadcast channel signal block) or SIB1. After the terminal accesses the wide-coverage cell A, it serves as a signaling bearer cell. When the service quality is higher than the threshold, it is judged as a high-rate cell (visible light cell, terahertz cell, high-frequency cell) by judging messages such as SSB or SIB1. At this time, if the signal quality of the high-rate cell is higher than a certain threshold, the high-rate cell is added to the service cell of the terminal. It is judged as a wide-coverage cell by judging messages such as SSB or SIB1. At this time, if the signal quality of the wide-coverage cell is higher than a certain threshold, the wide-coverage cell is switched with the original wide-coverage cell or the primary and secondary cells are changed. Therefore, the cell type (data or wide coverage cell) can be used as an important basis for cell switching or changes in primary and secondary cells.

[0154] When the terminal determines that it is at the edge of wide coverage cell A, it will measure cell C and cell B at the same time. The terminal will decide which cell to switch to based on whether cell B and C are wide coverage cells or high-rate cells. If cell C is a wide coverage cell and cell B is a high-rate cell, the terminal determines whether wide coverage cells A and C are in the same frequency network:

[0155] If it is a co-frequency network: To prevent co-frequency interference, the terminal will not switch directly between cells A and C. If both wide-coverage cell A and high-rate cell B are service cells of the terminal, the primary cell change process is performed between cells A and B, and then the switch is made from cell B to cell C or cell C is used as the primary cell; if cell B is a neighboring cell of wide-coverage cell A at this time, the terminal performs a switching process from cell A to high-rate cell B, performs inter-frequency switching to reduce interference, and then switches from B to cell C.

[0156] If it is an inter-frequency network: the terminal directly switches between cells A and C, cell C is used to transmit signaling information, and cell B is used as a data base station to provide temporary wide-coverage cell services or as a data transmission cell.

[0157] By using the solution of the embodiment of the present application, by obtaining whether the cell is a high-rate cell or a wide-coverage cell, the terminal or base station is helped to determine the target cell for switching, which not only ensures the reliable connection of the signaling, but also facilitates the reasonable switching of the terminal and solves the mobility problem. At the same time, using terahertz and visible light in local and short-distance communication can provide greater capacity and higher rate.

[0158] In summary, through the above combination and switching process, it is possible to ensure reliable connection and high-speed data transmission services of the terminal during the networking process.

[0159] For the network device, in this step, the network device can obtain second information from the terminal, wherein the second information is used to indicate the service quality of the current service cell of the terminal and the service quality of the neighboring cell, or the second information is used to indicate whether the service quality of the current service cell meets the conditions for cell switching or selection or reselection and the service quality of the neighboring cell.

[0160] Combination Figure 5 , when the current serving cell of the terminal is a first type cell and it is determined according to the second information that the service quality of the current serving cell does not meet the cell switching, selection or reselection condition:

[0161] If it is determined according to the first information that the neighboring cell is a second type cell and the service quality of the second type cell is higher than that of the current serving cell, use the second type cell as a secondary cell;

[0162] If it is determined according to the first information that the neighboring cell is a first type of cell and the service quality of the first type of cell is higher than that of the current serving cell, taking the neighboring cell as a target cell for performing cell switching, selection or reselection;

[0163] or

[0164] In a case where the current serving cell of the terminal is a first type cell and it is determined according to the second information that the service quality of the current serving cell meets the condition for cell switching, selection or reselection:

[0165] If it is determined according to the first information that the neighboring cell is a first type of cell, the neighboring cell and the current serving cell are in an inter-frequency network, and the service quality of the neighboring cell is higher than that of the current serving cell, the neighboring cell is used as a target cell for performing cell switching, selection, or reselection;

[0166] If it is determined based on the first information that the neighboring cells include first type cells and second type cells, the neighboring cells and the current service cell are in the same frequency network, and the service quality of the neighboring cells is higher than that of the current service cell, after performing cell switching or selecting or reselecting to the second type cell from the current service cell, performing cell switching or selecting or reselecting to the first type cell from the second type cell.

[0167] For example, if the second information is used to indicate the service quality of the current serving cell of the terminal, the network device may determine whether the service quality of the current serving cell meets the conditions for cell switching, selection or reselection based on the second information. If the second information is used to indicate whether the service quality of the current serving cell meets the conditions for cell switching, selection or reselection, the network device may directly determine whether the service quality of the current serving cell meets the conditions for cell switching, selection or reselection based on the second information.

[0168] After determining the target cell, the network device may further send third information to the terminal, wherein the third information is used to indicate to the terminal a target cell for performing cell switching, selection or reselection.

[0169] In an embodiment of the present application, by obtaining the first information indicating the cell type, cell switching, selection or reselection can be performed, thereby ensuring the communication quality. When the terminal is in the overlapping coverage area of ​​the wide coverage cell and the high-rate cell, the wide coverage cell is ensured to be the main cell to provide wide area coverage. At the same time, the high-rate cell can provide high-rate transmission and greater capacity. Through the identification of the high-rate cell and the wide coverage cell, the terminal or base station is helped to select a suitable target cell, thereby achieving better communication quality.
