Detailed Description
The following description of the technical solutions in the embodiments of the present disclosure will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
The present disclosure provides a communication method in a network co-building sharing scenario, and is described below with reference to fig. 1-2.
Fig. 1 is a flow chart of some embodiments of the disclosed method. As shown in fig. 1, the method of this embodiment includes: steps S102 to S106.
In step S102, the shared base station periodically acquires terminal information of each shared carrier.
Each shared carrier belongs to different operators, and the shared carrier may correspond to a cell. For example, the frequency band of the shared carrier 1 is 0-100M, and belongs to the operator a, that is, the frequency band of 0-100M is adopted in the cell of the operator a to interact with the terminal, and the frequency band of the shared carrier 2 is 100-200M and belongs to the operator B, that is, the frequency band of 100-200M is adopted in the cell of the operator B to interact with the terminal. There may be more than two operators' shared carriers (cells) under a shared base station. The shared base station periodically executes steps S102 to S106.
The terminal information includes, for example: the state of the terminals of the first type of service and the number of the terminals in each state, and the state of the terminals of the second type of service and the number of the terminals in each state, the transmission delay requirement of the first type of service is lower than that of the second type of service, and the transmission reliability requirement is higher. For example, the first type of traffic includes very URLLC traffic and the second type of traffic includes eMBB traffic.
In some embodiments, each state includes: a CONNECTED state (e.g., RRC-CONNECTED) and an INACTIVE state (e.g., RRC-INACTIVE). The terminal in the inactive state can be irregularly activated to be in a connection state, the terminal is considered, the condition that the terminal is incapable of serving or resources are stricken due to the state conversion is avoided, and the access efficiency and the service quality can be effectively improved.
In step S104, the shared base station determines access instruction information corresponding to each shared carrier according to the terminal information of each shared carrier.
The access indication information is used to indicate whether or not a terminal of a new first type of service is allowed to access. In some embodiments, the shared base station determines load parameters corresponding to each shared carrier according to terminal information in each shared carrier, wherein for each shared carrier, the larger the number of terminals in each state of the first type service, the smaller the number of terminals in each state of the second type service, and the higher the corresponding load parameters; and the shared base station determines the access indication information corresponding to each shared carrier according to the load parameters of each shared carrier. The generalized load analyzer can be added in the shared base station to determine the load parameters corresponding to the shared carriers.
Further, the number of the terminals in each state of the first type of service is weighted and summed to obtain a first load value; the number of the terminals in each state of the second type service is weighted and summed to obtain a second load value; a ratio of the first load value to the second load value is determined as a load parameter.
In some embodiments, for terminals of the first type of service, the number of terminals in a connected state corresponds to a greater weight than the number of terminals in a non-active state; for terminals of the second type of service, the weight corresponding to the number of terminals in a connected state is greater than the weight corresponding to the number of terminals in a non-activated state. For example, the weight corresponding to the number of the terminals in the first type service inactive state is 0.1 to 0.3, and the weight corresponding to the number of the terminals in the first type service inactive state is 0.1 to 0.3.
For example, taking the first type of service as a URLLC service and the second type of service as an eMBB service, each state includes a connection state and an inactive state as an example, for the ith shared carrier, the load parameter may be determined by using the following formula:
wherein connected_urllc_num [ i ] represents the number of terminals of the URLLC service in the connection state of the i-th shared carrier (cell), inactive_urllc_num [ i ] represents the number of terminals of the URLLC service in the non-active state of the i-th shared carrier (cell), connected_ebmb_num [ i ] represents the number of terminals of the ebbe service in the connection state of the i-th shared carrier (cell), inactive_ebmb_num [ i ] represents the number of terminals of the ebbe service in the non-active state of the i-th shared carrier (cell), and α and β are weights, i.e., influence factors, of inactive_urllc_num [ i ] and inactive_ebmb_num [ i ], respectively.
In some embodiments, after determining the load parameter of each shared carrier, the shared base station determines whether the load parameter of each shared carrier is greater than or equal to a load parameter threshold; and under the condition that the load parameters of the shared carriers are larger than or equal to the load parameter threshold, the shared base station determines the access indication information corresponding to the shared carriers as information for indicating that the terminal of the new first type service is not allowed to access.
For example, assuming that there are shared carriers respectively belonging to the carrier a and the carrier B under the shared base station, the load_parameter [ a ] is greater than or equal to the relative Load Parameter Threshold load_parameter_threshold, and the load_parameter [ B ] is greater than or equal to the relative Load Parameter Threshold load_parameter_threshold, the access indication information corresponding to each shared carrier is information indicating that the terminal of the new first type service (for example, URLLC) is not allowed to access.
In some embodiments, when the load parameter of the shared carrier is smaller than the load parameter threshold and the load parameters of the shared carriers are not equal, the shared base station determines a minimum value in the load parameters of the shared carriers, determines access indication information corresponding to the shared carrier corresponding to the minimum value as information indicating that the terminal of the new first type service is allowed to access, and access indication information of other shared carriers except the shared carrier corresponding to the minimum value is information indicating that the terminal of the new first type service is not allowed to access.
For example, if load_parameter [ a ] and load_parameter [ B ] are not both greater than or equal to load_parameter_threshold, and load_parameter [ a ] < load_parameter [ B ], the shared carrier of operator a is lighter, the access indication information corresponding to the shared carrier of operator a is information indicating that the terminal access of the new first type service (for example, URLLC) is allowed, and the access indication information corresponding to the shared carrier of operator B is information indicating that the terminal access of the new first type service is not allowed. Accordingly, if load_parameter [ a ] > load_parameter [ B ], the shared carrier of the carrier B is loaded lighter, the access indication information corresponding to the shared carrier of the carrier a is information indicating that the terminal access of the new first type service (for example, URLLC) is not allowed, and the access indication information corresponding to the shared carrier of the carrier B is information indicating that the terminal access of the new first type service is allowed
In some embodiments, the shared base station determines the access indication information corresponding to each shared carrier as information indicating that the terminal allowing the new first type service is accessed when the load parameter of the shared carrier is less than the load parameter threshold and the load parameters of each shared carrier are equal.
For example, if load_parameter [ a ] and load_parameter [ B ] are both less than load_parameter_threshold, and load_parameter [ a ] =load_parameter [ B ], the access indication information corresponding to each shared carrier is information indicating that the terminal of the new first type service (for example, URLLC) is allowed to access.
The method of the above embodiment is equally applicable to the case where there are shared carriers belonging to more than two operators under a shared base station, and is not limited to the illustrated example.
In step S106, the shared base station transmits broadcast information on each shared carrier.
The broadcast information sent on each shared carrier includes access indication information corresponding to the shared carrier. In some embodiments, for each shared carrier, the shared base station adds access indication information corresponding to the shared carrier to an idle bit (spark) of a MIB (Main Information Block, master information block) corresponding to the shared carrier; the shared base station broadcasts the corresponding MIB on each shared carrier. For example, 1bit is added to the spark field of the MIB to indicate access indication information. For example, 1 indicates Barred (terminal access for the first type of service is not allowed), and 0 indicates notBarred (terminal access for the first type of service is allowed), not limited to the illustrated example.
In some embodiments, the access indication information in the broadcast information first transmitted on each shared carrier is used to indicate that the terminal of the new first type of service is allowed to access. That is, after the shared carrier base station is started and initialized, broadcast information sent on each shared carrier for the first time indicates that a terminal of a new first type service is allowed to access.
Step S108 may also be included after step S106.
In step S108, the terminal of the first type service receives broadcast information transmitted on each shared carrier.
Because of the shared carrier, terminals of different operators can receive broadcast information on the shared carrier.
In step S110, the terminal of the first type service performs cell reselection or handover according to the broadcast information sent on each shared carrier.
The terminal of the first type service may determine whether each shared carrier is accessible according to the broadcast information sent on each shared carrier, and then select a shared carrier (cell) by combining access indication information in the broadcast information when the terminal of the first type service needs to perform cell reselection (e.g., an INACTIVE state terminal) or handover (e.g., a CONNECTED state terminal). For example, according to existing cell reselection criteria, a URLLC terminal residing in the shared carrier of operator a may reselect to the shared carrier of operator B, but the spark field in the MIB of the shared carrier of operator B indicates Barred, and the URLLC terminal will not reselect to the shared carrier of operator B.
The cell reselection or handover performed by the terminal of the second type of service may refer to the prior art, and will not be described herein.
In the solution of the above embodiment, the shared base station periodically acquires terminal information on each shared carrier belonging to different operators, including a state of a terminal of a first type service and the number of terminals in each state, and a state of a terminal of a second type service and the number of terminals in each state; and further determining whether each shared carrier allows the terminal of the new first type service to be accessed according to the terminal information of each shared carrier, and generating corresponding access indication information. The sharing base station sends the access indication information corresponding to each sharing carrier to the terminal through the broadcast information, so as to guide the terminal of the first type service to access each sharing carrier. According to the scheme of the embodiment, the broadcast information is generated by periodically and comprehensively considering the number of the terminals in different types of services and different states, so that the terminals in the first type of service can select proper shared carriers for migration and access, excessive preemption of resources by the terminals in the different types of service is avoided, access time delay of the terminals in the first type of service is reduced, network resource utilization rate is improved, and service quality and user experience are improved.
In the following, with reference to fig. 2, some application examples of the present disclosure will be described by taking a case where there are shared carriers (cells) under a shared base station, which are respectively assigned to a shared carrier a and a shared carrier B, and a first type of service is a URLLC service and a second type of service is an eMBB service, where each state includes a connection state and an inactive state.
In step S202, the SA-sharing base station is powered on and initialized, MIB- > URLLC-barred=notbarred (indicating that the access indication information is for allowing terminal access of URLLC). The shared base station can start the generalized load analyzer to execute the subsequent flow after being started.
In step S204, the number of URLLC connected terminals, URLLC inactive terminals, eMBB connected terminals, and eMBB inactive terminals in the shared carriers (cells) respectively belonging to the operator a and the operator B is acquired.
In step S206, load parameters corresponding to the shared carriers (cells) respectively assigned to the operator a and the operator B are determined.
The Load parameters load_parameter [ a ] and load_parameter [ B ] corresponding to the shared carriers (cells) belonging to the operators a and B can be calculated according to the formulas of the foregoing embodiments.
In step S208, it is determined whether the load_parameter [ a ] and the load_parameter [ B ] are both greater than or equal to the load_parameter_threshold, if so, step S210 is executed, otherwise, step S212 is executed.
In step S210, NR broadcast message MIB- > URLLC-barred=barred, which belongs to the shared carrier (cell) of operator a and operator B, respectively.
In step S212, it is determined whether Load_Parameter [ A ] is less than Load_Parameter [ B ]. If yes, step S214 is performed, otherwise step S216 is performed.
In step S214, the NR broadcast message MIB- > URLLC-barred=notbarred of the shared carrier belonging to operator a, and the NR broadcast message MIB- > URLLC-barred=barred of the shared carrier belonging to operator B.
In step S216, it is determined whether Load_Parameter [ A ] is equal to Load_Parameter [ B ]. If yes, step S218 is performed, otherwise step S220 is performed.
In step S218, NR broadcast message MIB- > URLLC-barred=notbarred, which belongs to the shared carrier (cell) of operator a and operator B, respectively.
In step S220, the NR broadcast message MIB- > URLLC-barred=barred of the shared carrier belonging to operator a, and the NR broadcast message MIB- > URLLC-barred=non-tbared of the shared carrier belonging to operator B.
Steps S204 to S220 are periodically repeated.
The method is applied to a scene that URLLC service and eMBB service are mixed together in a shared co-established network, and SA shared base stations analyze the relative load of each shared carrier by comprehensively considering the number of terminals in the CONNECTED and INACITIVE states of the eMBB and the URLLC in each shared carrier belonging to different operators to obtain the load condition, so that the aim of adjusting the strategy of reselection or switching of URLLC terminals in real time is fulfilled. The instantaneous load change condition of each shared carrier can be predicted in advance, URLLC user access is effectively controlled, URLLC terminals are allowed to reside in the optimal carrier preferentially, RRC connection is initiated at the frequency point at any time, monitoring, waiting and switching related to load balancing are reduced, access time delay is reduced, and normal access and real-time responsiveness of eMBB terminals are also ensured; and the eMBB and URLLC user experience under 5G SA sharing is improved, the utilization rate of shared network resources is improved, and the improvement of the 5G SA shared carrier technical scheme is facilitated. The completeness of the SA shared carrier technical scheme is improved, the network building, operation and service development cost is reduced, and the flexibility, the robustness, the compatibility and the robustness of the system are improved; the system has less modification to the existing system, low realization complexity and easy system realization and scheme popularization.
