[0029] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0030] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present invention. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0031] In various embodiments of the present invention, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0032] Additionally, the terms "system" and "network" are often used interchangeably herein.

[0033] In the embodiments provided herein, it should be understood that "B corresponding to A" means that B is associated with A and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B based solely on A; B can also be determined based on A and / or other information.

[0034] like Figure 1 As shown, a system message broadcasting method according to an embodiment of the present invention is applied to a terminal, and the method includes but is not limited to the following steps:

[0035] Step 11: Receive a system message sent by the first cell, where the system message includes at least one of the following: a first identifier used to indicate that the type of the first cell is a data cell and a signaling cell, wherein the signaling cell refers to a cell for establishing a radio resource control RRC connection, and the data cell refers to a cell for transmitting data and no RRC connection is established.

[0036] Optionally, when the first cell is a data cell, the system message further includes: a second identifier for indicating a second cell corresponding to the first cell, where the second cell is a signaling cell.

[0037] In order to reduce the bottleneck problem of dense network construction, it is necessary to consider a flexible and dynamic network construction method. The embodiment of the present invention can adopt a plug-and-play method for network construction, so that cells can be dynamically added according to the development of business. For example, in hot spots, more data base stations can be turned on to provide users with better services. In areas with low business demand, some data base stations can be turned off to save network energy consumption. This can directly reduce the cost of network construction, effectively reduce network energy consumption and scale redundancy, thereby achieving cost and power consumption savings. In the decoupling of signaling and data, the base station is divided into independent data base stations (corresponding to one or more data cells) and signaling base stations (corresponding to one or more signaling cells) according to its function. In the embodiment of the present invention, one of the first cell and the second cell is a signaling cell, and the other of the first cell and the second cell is a data cell, so that signaling and data decoupling can be achieved. Among them, the cell responsible for data transmission is called a data cell. By decoupling data and signaling, wide-area coverage of signaling can be achieved and the number of handovers can be reduced.

[0038] Furthermore, compared with the traditional CU-DU architecture, the embodiment of the present invention is different from the traditional CU-DU architecture, which divides the network functions horizontally according to the processing time requirements. In the embodiment of the present application, the architectural division of the signaling cell and the data cell is vertically divided according to the specific functions. The signaling base station / signaling cell completes the processing of the entire signaling plane protocol stack. The signaling cell serves as the anchor point of RRC signaling, is responsible for generating Radio Resource Control (RRC) messages, processing RRC messages from the terminal and messages from the core network control plane network elements, and is responsible for signaling connections and wide area coverage. The data base station / data cell is added on demand, mainly completing the processing of data plane signaling and some potential processing that may assist the signaling plane, such as using the random resources of the data cell as a forwarding point for RRC signaling between the control cell and the terminal. Among them, the data cell and the signaling cell together provide complete functions.

[0039] Since signaling cells and data cells have different functions, and neither data cell nor signaling cell can provide complete functions, there is a correspondence between data cells and signaling cells. There can be multiple data cells within the coverage of a signaling cell, and these data cells need to cooperate with the signaling cell, such as UE identification and UE context maintenance. Similarly, a data cell with overlapping coverage of a signaling cell can also have a correspondence with multiple signaling cells at the same time. This correspondence depends on the signaling cell to which the terminal in the data cell belongs, and is a terminal-level correspondence.

[0040] Optionally, after step 11, the method further includes:

[0041] Step 12: Establish a radio access resource RRC connection with the first cell or the second cell according to the system message.

[0042] In the embodiment of the present invention, a system message is used to indicate that the first cell is a data cell or a signaling cell, so that at the beginning of access, the terminal can distinguish between the data cell and the signaling cell existing in the current network. The signaling cell performs signaling plane functions and provides wide-area signaling coverage through low-frequency signaling cells to ensure the reliability of the control plane, such as reliable mobility management and fast service access. The data cell performs user plane operations and is responsible for data transmission. It can quickly upgrade the data processing capability of the network in a plug-and-play manner, and can dynamically adjust the network capability according to the network situation to achieve a match between network capability and actual needs. On the other hand, the embodiment of the present invention can also improve the data transmission capability of the network and reduce interference between cells through dynamic data base station loading.

[0043] Furthermore, the system message may also indicate a second identifier of a signaling cell corresponding to the data cell, so that the terminal can identify the association between the data cell and the signaling cell through the system message, thereby helping the terminal select a network and allowing the terminal to select a suitable network for random access.

[0044] Optionally, in a scenario where the signaling cell and the data cell are separated, embodiments of the present invention may employ a coordinated broadcasting method for the signaling cell and the data cell. In embodiments of the present invention, the first cell may be a data cell or a signaling cell. In addition to receiving system messages sent by the first cell, the terminal may also receive system messages sent by the second cell. This broadcast method, on the one hand, enables plug-and-play of data cells, avoiding the impact of frequent changes in system messages when adding data cells. On the other hand, it also allows independent broadcast message transmission through the data cell and the signaling cell, reducing data interaction between the signaling cell and the data cell.

[0045] Furthermore, the first identifier and the second identifier in the system message sent by the first or second cell may be included in the Master Information Block (MIB), System Information Block (SIB1), and other System Information (OSI). That is, on the network side, the data cell and the signaling cell each send their own system message, including the MIB, SIB1, and other SIBs. When the signaling cell and the data cell broadcast system messages, the system message may carry a cell type identifier, referred to as the first identifier, to distinguish whether the system message corresponds to a data cell or a signaling cell. For example, the first identifier may be carried in the MIB, and the SIB1 reception configuration for the same cell may be obtained through the MIB. Upon receiving the SIB1 message, the cell type identifier corresponding to the SIB1 is assumed to be the same as the corresponding MIB. Based on the system information scheduling configuration carried in the SIB1, the cell type corresponding to the remaining received system information is also the same as the corresponding SIB1 and MIB. The first identifier may also be carried in the MIB, SIB1, and other SIBs. Accordingly, on the terminal side, the terminal reads the first identifier in the MIB to identify the corresponding cell as a data cell or a signaling cell. SIB1 read according to the configuration in the MIB, and system information obtained through other system information configurations of SIB1 are considered to have the same cell type attributes as the MIB, such as data cell or signaling cell.

[0046] Optionally, the first identifier includes 1 bit, and when the 1 bit is a first value, it indicates that the type of the first cell is a signaling cell, and when the 1 bit is a second value, it indicates that the type of the first cell is a data cell. For example, the first identifier can be represented by 1 bit, for example, 0 represents a data cell and 1 represents a signaling cell.

[0047] Optionally, in order to enable the terminal to identify the signaling cell corresponding to the data cell, a corresponding signaling cell identifier is added to the system message, which is referred to as a second identifier. The second identifier can be the physical cell identifier of the signaling cell, or a cell number that uniquely identifies a cell within an area. For example, the second identifier satisfies at least one of the following:

[0048] The second identifier indicates a physical cell identifier of at least one second cell corresponding to the first cell;

[0049] The physical cell identifier of the second cell indicated by the second identifier is the same as the physical cell identifier of the first cell;

[0050] The physical cell identifier of the second cell indicated by the second identifier is determined according to the physical cell identifier of the first cell.

[0051] For example, the network side adds a second identifier to the system message according to the correspondence between the data cell and the signaling cell. The second identifier of the data cell can correspond to the physical cell ID or the second identifier corresponding to the signaling cell, including the following possible situations: the data cell and the signaling cell use the same second identifier, or the second identifier of the data cell is equal to the physical cell ID of the signaling cell, or the second identifier of the data cell can be derived from the second identifier or the physical cell ID of the signaling cell. When the data cell needs to correspond to one or more information cells, the second identifier can carry one or more physical cell IDs or network labels.

[0052] On the terminal side, the terminal receives the system information system broadcast, first determines that the current cell is a signaling cell by using the first identifier as the signaling cell, and thereby determines the physical cell ID and / or second identifier of the signaling cell. Then, the terminal determines that the current cell is a data cell by using the first identifier as the data cell, obtains the second identifier in the system information of the data cell, and compares the second identifier of the current cell with the physical cell ID and / or second identifier in the signaling cell to determine the signaling cell corresponding to the data cell.

[0053] Optionally, step 12 includes: the terminal establishing an RRC connection with a signaling cell in the first cell and the second cell. This can be achieved by:

[0054] Method 1: By identifying the first identifier in the system information of the first cell or the second cell, an RRC connection establishment request message is sent to the data cell in the first cell and the second cell; wherein, after receiving the RRC connection establishment request message, the data cell forwards it to the signaling cell indicated by the second identifier; and receives the RRC connection establishment response message sent by the data cell; the RRC connection establishment response message is fed back to the data cell by the signaling cell after receiving the RRC connection establishment request message.

[0055] Method 2: By identifying the first identifier in the system information of the first cell or the second cell, an RRC connection establishment request message is sent to the signaling cell in the first cell and the second cell; an RRC connection establishment response message is received from the signaling cell; the RRC connection establishment completion message is fed back to the terminal by the signaling cell after receiving the RRC connection establishment request message.

[0056] Optionally, after step 12, the method further includes: sending an RRC connection establishment completion message to a signaling cell in the first cell and the second cell.

[0057] like Figure 2 As shown, it is assumed that the physical cell ID of the signaling cell is 1, the cell type carried in the system information broadcast of signaling cell 1 is signaling cell, and the cell type in the system information broadcast of data cell A covered by signaling cell 1 is data cell, and its corresponding second identification mark is the same as the signaling cell ID, which is also A. After the terminal receives the system broadcasts of signaling cell 1 and data cell A, it distinguishes their respective types through the first identification, and then learns through the second identification that the signaling cell associated with data cell A is signaling cell 1. Subsequently, the terminal can initiate an RRC connection establishment request (access request) on data cell A through method 1. Data cell A forwards the RRC connection establishment request to signaling cell 1. Signaling cell 1 sends an RRC connection establishment response to data cell A. The RRC connection between data cell A and the terminal is established. Further, the terminal feedbacks the completion of the RRC connection establishment to signaling cell 1. Alternatively, the terminal can also initiate an RRC connection establishment request (access request) directly in signaling cell 1 through method 2. After receiving the RRC connection establishment response from signaling cell 1, the terminal establishes a signaling transmission bearer with signaling cell 1 and feedbacks the RRC connection establishment completion to signaling cell 1.

[0058] In the system message broadcasting method of the embodiment of the present invention, the cell type and the correspondence between the signaling cell and the data cell can be distinguished, the signaling cell and the data cell can be distinguished, the signaling and data can be decoupled more flexibly, and the traditional cell functions can be decomposed into the data cell and the signaling cell to improve the flexibility of the network and reduce the interaction between the data cell and the signaling cell.

[0059] The above describes the system message broadcasting method on the terminal side according to the embodiment of the present invention. The following will further describe the system message broadcasting method on the base station side with reference to the accompanying drawings.

[0060] like Figure 3 As shown, an embodiment of the present invention provides a system message broadcasting method, which is applied to a base station. The method includes but is not limited to:

[0061] Step 31: Send a system message to the terminal, where the system message includes: a first identifier for indicating that the type of the first cell is one of a data cell and a signaling cell, wherein the signaling cell refers to a cell for establishing a radio resource control RRC connection, and the data cell refers to a cell for data transmission and no RRC connection is established.

[0062] Optionally, the system message further includes: a second identifier for indicating a second cell corresponding to the first cell, wherein the second cell is another of a data cell and a signaling cell;

[0063] Optionally, after step 31, the method further includes:

[0064] Step 32: Establish a radio access resource RRC connection with the terminal according to the system message.

[0065] The first identifier and the second identifier may be included in the master information block MIB, the system information 1 SIB1 and other system information OSI.

[0066] The first identifier includes 1 bit. When the 1 bit is a first value, it indicates that the type of the first cell is a signaling cell. When the 1 bit is a second value, it indicates that the type of the first cell is a data cell.

[0067] The second identifier satisfies at least one of the following:

[0068] The second identifier indicates a physical cell identifier of at least one second cell corresponding to the first cell;

[0069] The physical cell identifier of the second cell indicated by the second identifier is the same as the physical cell identifier of the first cell;

[0070] The physical cell identifier of the second cell indicated by the second identifier is determined according to the physical cell identifier of the first cell.

[0071] Optionally, step 32 includes: when the base station is a data cell, receiving an RRC connection establishment request message sent by the terminal; sending the RRC connection establishment request message to the signaling cell; receiving an RRC connection establishment completion message corresponding to the RRC connection establishment request message sent by the signaling cell; and sending the RRC connection establishment completion message to the terminal.

[0072] Optionally, step 32 includes: when the base station is a data cell, receiving an RRC connection establishment request message sent by the terminal; and sending a corresponding RRC connection establishment completion message to the terminal according to the RRC connection establishment request message.
