Technical Field

Background

With the rapid development of communication technology, mobile communication has entered the fifth Generation mobile communication technology (5 th-Generation, 5G) era. Compared with the fourth Generation mobile communication technology (4 th-Generation, 4G), the carrier frequency of 5G is higher, and the coverage area of the base station is smaller. In order to accelerate the popularization of 5G services, the third generation partnership project (Third Generation Partnership Project,3 GPP) standards organization proposes a scheme of radio access network Sharing (Radio Access Network Sharing). RAN Sharing refers to a core network in which one base station is simultaneously connected to two or more operators, and resources of the base station are shared by the two or more operators.

In the 5G system, a next-generation base station (gNB) is composed of a gNB Distribution Unit (DU) and a gNB Concentration Unit (CU). And carrying out message interaction between the gNB-CU and the gNB-DU through an F1 interface. When the F1 interface is established, the gNB-DU sends an F1 start request message to the gNB-CU requesting that the gNB-CU indicate which operator cells are allowed to be activated. The F1 starting request message comprises configuration information of a plurality of operator cells, wherein the configuration information of each operator cell comprises physical cell configuration parameters and operator configuration parameters.

However, in the RAN Sharing scheme, the signaling overhead is large and the resource utilization is not high by adopting the method in the prior art.

Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.

Fig. 1 is a network architecture diagram for shared cell management according to an embodiment of the present disclosure, as shown in fig. 1, where the network architecture provided in the embodiment includes: the 5G core network of operator 1 (5Generation Core,5GC), the 5GC of operator 2 and the next generation radio access network (Next Generation Radio Access Network, NG-RAN).

The NG-RAN is respectively connected with the 5GC-A and the 5GC-B through NG interfaces. The NG-RAN includes: at least one gNB. The two gNBs are connected with each other through an Xn interface. One gNB includes: one gNB-CU and one or more gNB-DUs. The gNB-CU and the gNB-DU are connected with each other through an F1 interface.

A method for managing a shared cell according to an embodiment of the present disclosure will be described in detail based on a network architecture diagram shown in fig. 1.

Fig. 2 is a flow chart of a method for managing a shared cell according to an embodiment of the present disclosure, as shown in fig. 2, where the method in this embodiment includes:

s201, gNB-DU generates a first request message.

The first request message includes configuration information of a plurality of physical cells, wherein the configuration information of each physical cell includes a physical cell configuration parameter and at least two operator cells sharing the physical cell, which respectively correspond to the operator configuration parameters.

In the RAN Sharing scheme, a plurality of New Radio (NR) physical cells are configured on the gNB-DU, and the same physical cell may be shared by a plurality of operators, so that configuration information of each physical cell includes an operator configuration parameter related to the operator and a physical cell configuration parameter unrelated to the operator.

The physical cell configuration parameters include, but are not limited to, the following:

PCI；

NR Mode information (NR-Mode-Info), comprising: configuration parameters corresponding to frequency division duplexing and configuration parameters corresponding to time division duplexing;

timing configuration information is measured (Measurement Timing Configuration).

Operator configuration parameters include, but are not limited to, the following:

NR CGI；

TAC；

RANAC。

in the first request message, the NR CGI is a parameter that must be contained, and the TAC and RANAC are optional parameters. The TAC comprises: 5G system tracking area code (5G System Tracking Area Code,5GS TAC) and 4G system tracking area code (Configured Evolved Packet Core Tracking Area Code, configured EPS TAC). Currently, two schemes are defined by 3GPP for 5G networking, independent networking and dependent networking, respectively. The independent networking means newly-built 5G network, comprising a core network and a wireless access network; the non-independent networking refers to deployment of a 5G network by using an existing 4G infrastructure, that is, using a 4G core network, a 4G radio access network, and a 5G radio access network simultaneously. For the gNB in the 5G network of the independent networking, the 5GS TAC is a parameter that must be contained in the first request message; for a gNB in a 5G network that is not independently networked, configured EPS TAC is a parameter that must be included in the first request message. RANAC is a parameter that must be included in the first request message when the gNB supports the radio access network based notification zone management function.

For example: in an independently networked 5G network, only one physical cell pci_1 is configured on the gNB-DU, and two operators (operator 1, operator 2) share the physical cell. The configuration information of pci_1 includes: physical cell configuration parameters, operator configuration parameters corresponding to the operator 1 cell, and operator configuration parameters corresponding to the operator 2 cell. Wherein the physical cell configuration parameters include: NR PCI of PCI_1, NR mode information of PCI_1 and measurement timing configuration information of PCI_1; the operator configuration parameters corresponding to the operator 1 cell include: NR CGI for operator 1 and 5GS TAC for operator 1; the operator configuration parameters corresponding to the operator 2 cell include: NR CGI of operator 2 and 5GS TAC of operator 2.

The cells included in the first request message generated by the gNB-DU are shown in Table 1.

TABLE 1

IE/Group Name (cell/Group Name)
	NR PCI of PCI_1
NR mode information of PCI_1
	Measurement timing configuration information for PCI_1

	5GS TAC for operator 2

Alternatively, the first REQUEST message may be an F1 startup REQUEST (F1 SETUP REQUEST) message; alternatively, the first request message may be a DU configuration update request (GNB-DU CONFIGURATION UPDATE) message.

S202, the gNB-DU sends a first request message to the gNB-CU.

Wherein the first request message is for requesting information that the CU indicates the allowed active operator cells.

One possible implementation is: when the F1 interface is established, the gNB-DU sends an F1 starting request message to the gNB-CU, and the size of the F1 starting request message is reduced because the F1 starting request message only carries one physical cell configuration parameter, so that signaling occupied by the F1 starting request message is reduced, and the radio resource utilization rate is improved.

Another possible implementation is: if the cell configuration information on the gNB-DU changes, for example, a physical cell is added through the operation maintenance management system, the gNB-DU sends a DU configuration update request message to the gNB-CU, and the size of the DU configuration update request message is reduced because the DU configuration update request message only carries one physical cell configuration parameter, thereby reducing signaling occupied by the DU configuration update request message and improving the utilization rate of wireless resources.

S203, the gNB-CU determines information of the activated operator cell according to the network state and the first request message.

And the gNB-CU acquires the information of all the operator cells corresponding to one physical cell according to the first request message, and determines the information of the activated operator cells according to the current network state.

Wherein the information of the activated operator cell includes, but is not limited to, the following parameters:

NR CCI；

NR PGI。

s204, the gNB-CU sends a first response message to the gNB-DU.

Wherein the first response message contains information of the allowed activated operator cell.

One possible implementation is: if the first REQUEST message in S202 is an F1 SETUP REQUEST message, the gNB-CU sends an F1 startup RESPONSE (F1 SETUP RESPONSE) message to the gNB-DU.

Another possible implementation is: if the first request message in S202 is a GNB-DU CONFIGURATION UPDATE message, the gNB-CU sends a DU configuration update confirm (GNB-DU CONFIGURATION UPDATE ACKNOWLEDGE) message to the gNB-DU.

For example: the cells included in the first request message received by the gNB-CU are shown in Table 1, the gNB-CU determines to activate all the operator cells according to the network state and the first request message, and sends a first response message to the gNB-DU. The cells included in the first response message are shown in table 2.

TABLE 2

IE/Group Name (cell/Group Name)
	NR PCI of PCI_1
NRCGI of operator 1
	NRCGI of operator 2

Whereas in the prior art, the first request message repeatedly carries the physical cell configuration parameters. The more operators sharing the same physical cell, the more the number of times the physical cell configuration parameters are repeated, and the greater the signaling load. The cells contained in the first request message are as shown in Table 3

TABLE 3 Table 3

IE/Group Name (cell/Group Name)

	Measurement timing configuration information for PCI_1

	NR mode information of PCI_1
Measurement timing configuration information for PCI_1
	NRCGI of operator 2
5GS TAC for operator 2

The first request message sent by the DU to the CU contains configuration information of a plurality of physical cells, and the configuration information of each physical cell contains configuration parameters of the physical cell and configuration parameters of operators respectively corresponding to at least two operators sharing the physical cell. Because the configuration parameters of the corresponding physical cells are the same for at least two operator cells sharing a certain physical cell, the configuration information of the physical cell is carried only once, so that the signaling redundancy of the configuration information of the physical cell is reduced, the size of the first request message is reduced, the signaling overhead is reduced, and the radio resource utilization rate and the information transmission efficiency are improved.

Optionally, the configuration information of each physical cell is stored in the form of an array. The array comprises n+1 subarrays, wherein one subarray corresponding to the physical cell configuration parameter corresponds to one subarray, and the operator configuration parameter of each operator cell in N operator cells sharing the physical cell corresponds to one subarray, wherein N is an integer greater than or equal to 2.

One possible cell format for the configuration information for each physical cell is: a list of cell identification information of operator 1 sharing the physical cell, a list of cell identification information of operator 2 sharing the physical cell, …, a list of cell identification information of operator N sharing the physical cell, physical cell configuration parameters. The service cell identification information list contains operator configuration parameters of the operator cell. The configuration information for each physical cell is shown in table 4.

IE/Group Name (cell/Group Name)	Range (Range)
		List of serving cell identification information	1..<N>
>NR CGI
		>5GS TAC
>Configured EPS TAC
		>RANAC

The number of sub-arrays included in the array of configuration information of each physical cell may be defined according to actual requirements. For example: according to the number limit of the shared operators supported by one physical cell, if one physical cell is shared by 12 operators, 13 arrays are included in the array of the configuration information of the physical cell; or, defining the maximum message length of the starting request message according to F1; or, defined by the data size allowed to pass by the F1 interface. The present disclosure is not limited in this regard.

For example: the gNB-DU is deployed in a 5G network of independent networking, with two physical cells PCI_1 and PCI_2, and each physical cell is shared by two operators (operator 1, operator 2). The configuration information of pci_1 includes: sub-array 1 (NR cgi_1 of carrier 1 and 5GS tac_1 of carrier 1), sub-array 2 (NR cgi_1 of carrier 2 and 5GS tac_1 of carrier 2), and sub-array 3 (NR pci_1); the configuration information of pci_2 includes: sub-array 1 (NR cgi_2 of carrier 1 and 5GS tac_2 of carrier 1), sub-array 2 (NR cgi_2 of carrier 2 and 5GS tac_2 of carrier 2), and sub-array 3 (NR pci_2).

Fig. 3 is a flow chart of another method for managing a shared cell according to an embodiment of the present disclosure, and fig. 3 is a flowchart of another method for managing a shared cell according to an embodiment of fig. 2, further including:

s301, the gNB-CU determines information of the deactivated physical cells according to the network state.

Wherein the information of the deactivated physical cell includes, but is not limited to, the following parameters:

NR PCI。

one possible implementation is: the gNB-CU determines the physical cell with reduced deactivated data traffic according to the condition of the data traffic in the network.

S302, the gNB-CU sends a configuration update message to the gNB-DU.

The configuration update message includes a deactivated cell list, where the deactivated cell list includes a physical cell identifier, and is configured to indicate all operator cells corresponding to the deactivated physical cell.

One possible implementation is: the gNB-CU sends a CU configuration update (GNB-CU CONFIGURATION UPDATE) message to the gNB-DU. The gNB-DU deactivates the cell according to the GNB-CU CONFIGURATION UPDATE message and returns a CU configuration update confirm message to the gNB-CU.

For example: there are two physical cells pci_1 and pci_2 on the gNB-DU, and each physical cell is shared by two operators (operator 1, operator 2), and CGIs corresponding to two operator cells sharing pci_1 are NR cgi_1 of operator 1 and NR cgi_1 of operator 2, respectively. The gNB-CU determines to deactivate PCI_1 based on the network status, and the cells contained in the configuration update message are shown in Table 5.

TABLE 5

IE/Group Name (cell/Group Name)
	Deactivating a cell list
>Deactivating information of a cell
	>>NR PCI_1

Whereas in the prior art, the cells contained in the configuration update message sent to the gNB-DU by the gNB-CU for deactivating PCI_1 are shown in Table 6.

TABLE 6

IE/Group Name (cell/Group Name)
	Deactivating a cell list
>Deactivating information of a cell
	>>NR CGI_1 of operator 1
>Deactivating information of a cell
	>>NR CGI_1 of operator 2

In the prior art, when the gNB-CU determines to deactivate one physical cell, the configuration update message needs to include CGI of all the operators corresponding to the physical cell, and the more operators served by the same physical cell, the more data carried in the configuration update message, and the greater the signaling load.

The method comprises the steps that the gNB-CU determines information of deactivated physical cells according to network states, and sends configuration update information to the gNB-DU, wherein the configuration update information comprises a deactivated cell list, and the deactivated cell list comprises physical cell identifiers used for indicating all operator cells corresponding to the physical cells to be deactivated. Because the corresponding physical cell identifiers of at least two operator cells sharing a certain physical cell are the same, the size of the deactivated cell list is reduced by carrying the physical cell identifiers in the deactivated cell list, thereby reducing the size of the CU configuration update message, reducing signaling overhead, and improving the real-time performance and system performance of information interaction.

Optionally, the gNB-CU also determines information of the activated physical cell according to the network state, and sends a configuration update message to the gNB-DU. Wherein the configuration update message contains information of the allowed activated operator cell. One possible cell format for the information of the allowed active operator cells is shown in table 2 above.

Another possible implementation of including information allowing the activated operator cell in the configuration update message is: the configuration update message contains a list of cells allowed to be activated. The activated cell list contains configuration information of a plurality of activated physical cells. The configuration information of each physical cell which is allowed to be activated is an array, the array comprises n+1 elements, NR PCI of the physical cell which is allowed to be activated corresponds to a subarray, CGI of each operator cell in N operator cells which share the physical cell corresponds to a subarray, and N is an integer greater than or equal to 2.

The cell format of the cell list allowed to be activated is shown in table 7.

TABLE 7

IE/Group Name (cell/Group Name)	Range (Range)
		Cell list allowing activation
>Configuration information for physical cells allowing activation
		>>NR PCI
>>NR CGI list	1..<N>
		>>>NR CGI

For example: there are two physical cells pci_1 and pci_2 on the gNB-CU, and each physical cell is shared by two operators (operator 1, operator 2). And if the gNB-CU determines to activate the physical cells PCI_1 and PCI_2 according to the network state, the configuration update message contains configuration information of 2 physical cells which are allowed to be activated in the cell list which is allowed to be activated. The configuration information of the physical cell which is allowed to be activated and corresponds to the PCI_1 comprises the following steps: sub-array 1 (NR pci_1), sub-array 2 (NR cgi_1 of carrier 1) and sub-array 3 (NR cgi_1 of carrier 2); the configuration information of the physical cell which is allowed to be activated and corresponds to the PCI_2 comprises the following steps: sub-array 1 (NR pci_2), sub-array 2 (NR cgi_2 of carrier 1) and sub-array 3 (NR cgi_2 of carrier 2).
