Description

Method and device for transmitting configuration parameters
Technical Field
The present application relates to wireless communication technologies, and in particular, to a method and apparatus for transmitting configuration parameters.
Background
In a next generation (NR) network or a fifth generation (5G) network, in order to support network function virtualization, a base station (e.g., gNB) providing a wireless network interface for a terminal (UE) may be further divided into a Central Unit (CU) and a Distributed Unit (DU). The CU has at least a Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP) protocol layer, etc., and may also include a service data adaptation protocol (Service Data Adaptation Protocol, SDAP). The DUs have radio link control protocol (RLC), medium Access Control (MAC), physical layer, etc. Between CU and DU is a standardized public interface F1. The F1 interface is divided into a control plane F1-C and a user plane F1-U.
The transport network layer of F1-C is based on Internet Protocol (IP) transport. For more reliable transport signaling, a stream control transmission protocol (Stream Control Transmission Protocol, SCTP) is added over IP. The protocol of the application layer is F1AP. SCTP may provide reliable application layer messaging. The transport layer of F1-U is User Datagram Protocol (UDP)/IP, and the GPRS tunneling protocol (GTP-U) of the user plane is used to carry user plane Protocol Data Units (PDUs) over UDP/IP. Fig. 1 shows the structure of CUs and DUs.
The centralized unit and the distributed unit each have corresponding configuration parameters, some of which are controlled by the centralized unit, some of which are controlled by the distributed unit, and some of which are controllable. When the centralized unit or the distributed unit updates these parameters, the other party needs to be notified. In addition, for some parameters that can both be controlled, when the central unit or the distribution unit modifies these parameters, it is necessary to inform the distribution unit or the central unit of the modified results, so that the correct parameter settings can be ensured. In the prior art, the centralized unit or the distributed unit notifies the setting of the configuration parameters of the other party, and also allows the parameters of the other party to be modified. However, there is often a problem in that the parameter modification fails.

Detailed Description
The present application will be described in further detail with reference to the accompanying drawings, in order to make the objects, technical means and advantages of the present application more apparent.
In the prior art, when a centralized unit or a distributed unit modifies a parameter of the distributed unit or the centralized unit, the centralized unit or the distributed unit does not know a reasonable value range of the parameter, so that the modified parameter value is unreasonable and exceeds the value range of the parameter, so that a user cannot access a network, and the user accesses the network too early or too late, and the like, thereby causing failure of parameter updating. This may occur when the update of the configuration parameters of the centralized or distributed unit is unsuccessful. In order to reduce such failures, the application provides a transmission method and device for configuration parameters, which consider how to update the configuration parameters between a centralized unit and a distributed unit, and particularly inform the reasonable value range of the configuration parameters of the other party in advance, so as to avoid the problem of failure in updating the parameters caused by that the parameter modification exceeds the reasonable range.
The problem addressed by the present invention is how to transmit respective configuration parameters between a centralized unit and a distributed unit of a base station. Examples of such configuration parameters include, but are not limited to, the following:
cell identity related parameters, such as PCI (physical cell identity), NCI (NR cell identity), NCGI (NR Cell Global Identity), etc
Identification information of neighbor cells of a cell
Parameters related to cell selection/reselection, such as minimum received signal strength information (q-RxLevMin) required for cell selection/reselection, offset information (q-RxLevMin offset) required for cell selection/reselection, etc

2. In the protocol (3GPP TS36.331,3GPP TS38.331) the parameter has a range of values, which may be a continuous set of values or a discrete set of values, which may be numerical values or enumerated values. The value of the parameter can only be set to a value within the range of values. For example, in LTE, the SIB1 message contains a cell selection parameter that is q-RxLevMin, and the range of values defined in TS36.331 is an integer of [ -77, -22 ].

The configuration parameters may be configuration parameters unique to the concentration unit, configuration parameters unique to the distribution unit, or configuration parameters common to the concentration unit and the distribution unit. The configuration parameters unique to the concentration unit and the configuration parameters common to the concentration unit and the distribution unit are hereinafter referred to as configuration parameters of the concentration unit, and the configuration parameters unique to the distribution unit and the configuration parameters common to the concentration unit and the distribution unit are hereinafter referred to as configuration parameters of the distribution unit. The configuration parameters of the centralized unit and the configuration parameters of the distributed unit may be all the parameters described above or may be a subset of the parameters described above. The configuration parameters of the centralized unit and the configuration parameters of the distributed units may be completely different, may be completely the same, or may be partially the same. The message names mentioned in the present invention are examples only, and other message names may be substituted.
The present application refers to a centralized unit and a distributed unit of base stations, which may be the base station gNB of NR, the base station eNB of LTE, or other types of base stations.
The transmission method of the configuration parameters is divided into two types, one type is that the centralized unit modifies the configuration parameters of the distributed units, and the other type is that the distributed units modify the configuration parameters of the centralized units. The following description will be made separately.
1. Configuration parameter modification of distributed units by centralized units
In the configuration parameter modification of the distribution unit by the concentration unit, the most basic method comprises the following steps:
a1, a concentration unit determines a value range of configuration parameters of a distribution unit;
b1, the centralized unit sends a first message to the distribution unit, wherein the first message comprises updated configuration information of configuration parameters of the distribution unit and is used for indicating updated configuration values of the configuration parameters of the distribution unit;
the update configuration information may be the update configuration value directly, or may be indication information of the update configuration value. For example, the values of the configuration parameters are 100, 1000 and 10000, in order to indicate the three values, the three values of 100, 1000 and 10000 can be directly used as update configuration information of the configuration parameters, or three indicating information, namely 1,2 and 3 are defined to respectively represent the values of 100, 1000 and 10000 of the parameters, if the value of the parameter is 100, the update configuration information can also be 2 instead of the specific 1000.
And C1, the distribution unit receives a first message of the concentration unit and updates corresponding configuration parameters according to the message.
In the above basic method, steps A1 and B1 are processing on the central unit side, and step C1 is processing on the distribution unit side, and the two are matched with each other to implement modification of configuration parameters. In step A1, when the central unit determines the value range of the configuration parameter of the distribution unit, the distribution unit may notify the central unit of the corresponding value range (corresponding to the subsequent mode 1 and mode 2), or may determine the value range according to a preset or system configuration (corresponding to the subsequent mode 3). In addition, the value range here refers to the value range of the corresponding configuration parameter of the distribution unit in the current environment and scene, that is, the current value range of the configuration parameter. In order to distinguish it from the updated value range, it is hereinafter referred to as the current value range.
Three specific implementations of the basic method described above are given below, taking this as an example. Of course, in practical application, the following three modes are not limited. In the description of the specific embodiments, for convenience, the description is made from the perspective of interaction of the centralized unit and the distributed unit.
1) Mode 1: the distribution unit sends a parameter configuration message to the concentration unit, and the concentration unit sends a parameter configuration response message to the distribution unit, in the manner shown in fig. 2:
step 1: the distribution unit sends a parameter configuration message to the concentration unit, where the message includes at least a current value range of a configuration parameter of the distribution unit, and in addition, preferably, at least one of the following information is included:
a. identification information of the distribution unit, such as DU ID. This identification information is the identification information used by the distribution unit when sending to the parameter configuration message. Alternatively, old identification information of the distribution unit may be included, where the identification information is identification information used before the distribution unit, but is not used at the current time (for example, new identification information is allocated after the distribution unit fails in hardware or is restarted);
b. identification information of at least one cell supported by the distribution unit, such as PCI, NCI, NCGI, etc. The identification information is the identification information of the at least one cell or an updated value of the identification information obtained before the parameter configuration message is sent to the distribution unit, and if the identification information is the updated value, old identification information of the cell can also be contained;
c.

In the configuration parameter modification of the centralized unit by the distributed unit, the most basic method comprises the following steps:

b2, the distribution unit sends a first message to the concentration unit, wherein the first message comprises updated configuration information of configuration parameters of the concentration unit and is used for indicating updated configuration values of the configuration parameters of the concentration unit;
wherein, as in 1, the update configuration information may be the update configuration value directly, or may be the indication information of the update configuration value;
and C2, the centralized unit receives the first message of the distribution unit and updates the corresponding configuration parameters according to the message.
In the basic method, steps A2 and B2 are processes on the side of the distribution unit, and step C2 is a process on the side of the concentration unit, and the two processes are mutually matched to realize modification of configuration parameters. In step A2, when the distribution unit determines the current value range of the configuration parameter of the central unit, the central unit may notify the distribution unit of the corresponding value range (corresponding to the subsequent mode 1 and mode 2), or may determine the current value range according to a preset or system configuration (corresponding to the subsequent mode 3). In addition, the value range herein refers to the value range of the corresponding configuration parameter of the corresponding centralized unit or cell under the current environment and scene, that is, the current value range of the configuration parameter. In order to distinguish it from the updated value range, it is hereinafter referred to as the current value range.
Three specific implementations of the basic method described above are given below, taking this as an example. Of course, in practical application, the following three modes are not limited. In the description of the specific embodiments, for convenience, the description is made from the perspective of interaction of the centralized unit and the distributed unit.

This identification information is the identification information used by the concentration unit when sending to the parameter configuration message. Alternatively, old identification information of the centralized unit may be included, where the old identification information is identification information used before the centralized unit, but is not used at the current time (for example, new identification information is allocated after the hardware failure or restarting of the centralized unit);
b. update identification information of at least one cell supported by the distribution unit, such as PCI, NCI, NCGI, etc., where the identification information is an update value of the identification information of the at least one cell obtained before the distribution unit receives the parameter configuration message, and may further include old identification information of the cell;
