Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the 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. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The present disclosure provides a communication method in a network co-construction sharing scenario, which is described below with reference to fig. 1 to 2.
Fig. 1 is a flow chart of some embodiments of the disclosed methods. 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 a different operator, and the shared carrier may correspond to a cell. For example, the frequency band of the shared carrier 1 is 0-100M, which belongs to the operator a, that is, the frequency band of 0-100M is used in the cell of the operator a for interacting with the terminal, and the frequency band of the shared carrier 2 is 100-200M, which belongs to the operator B, that is, the frequency band of 100-200M is used in the cell of the operator B for interacting with the terminal. There may be more than two operators' shared carriers (cells) under the shared base station. The shared base station periodically executes steps S102 to S106.
The terminal information includes, for example: the state of the terminal of the first type service and the number of the terminals in each state, and the state of the terminal of the second type service and the number of the terminals in each state, the requirement of the first type service on the transmission delay relative to the second type service is lower, and the requirement on the transmission reliability is higher. For example, the first type of traffic includes eurllc traffic and the second type of traffic includes eMBB traffic.
In some embodiments, the respective states include: CONNECTED state (e.g., RRC-CONNECTED) and INACTIVE state (e.g., RRC-INACTIVE). The terminal in the non-activated state can be irregularly activated into the connected state, and the part of the terminals is considered, so that the problem that the terminal cannot be served or resources are contended due to the conversion state is avoided, and the access efficiency and the service quality can be effectively improved.
In step S104, the shared base station determines access indication information corresponding to each shared carrier according to the terminal information of each shared carrier.
The access indication information is used for indicating whether the terminal of the new first type service is allowed to access. In some embodiments, the shared base station determines load parameters corresponding to the shared carriers according to the terminal information in the shared carriers, where for each shared carrier, the larger the number of terminals in each state of the first type of service is, the smaller the number of terminals in each state of the second type of service is, and the higher the corresponding load parameter is; 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 load parameter corresponding to each shared carrier can be determined by a new extension load analyzer in the shared base station.
Further, carrying out weighted summation on the number of the terminals in each state of the first type service to obtain a first load value; carrying out weighted summation on the number of the terminals in each state of the second type service to obtain a second load value; the ratio of the first load value to the second load value is determined as the load parameter.
In some embodiments, for the terminals of the first type of service, the weight corresponding to the number of terminals in the connected state is greater than the weight corresponding to the number of terminals in the inactive state; for the terminals of the second type of service, the weight corresponding to the number of the terminals in the connected state is greater than the weight corresponding to the number of the terminals in the inactivated state. For example, the weight value corresponding to the number of the terminals in the first type service inactive state is 0.1 to 0.3, and the weight value 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 URLLC service, the second type of service as eMBB service, and each state includes a connected state and an inactive state as an example, for the ith shared carrier, the load parameter may be determined by using the following formula:
the connection _ URLLC _ Num [ i ] indicates the number of terminals of the URLLC service in the i-th shared carrier (cell) in the CONNECTED state, the INACTIVE _ URLLC _ Num [ i ] indicates the number of terminals of the URLLC service in the i-th shared carrier (cell) in the INACTIVE state, the connection _ eMBB _ Num [ i ] indicates the number of terminals of the eMBB service in the CONNECTED state of the i-th shared carrier (cell), the INACTIVE _ eMBB _ Num [ i ] indicates the number of terminals of the eMBB service in the INACTIVE state of the i-th shared carrier (cell), and α and β are weights, i.e., impact factors, of the INACTIVE _ URLLC _ Num [ i ] and the INACTIVE _ eMBB _ 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 the shared base station determines that the access indication information corresponding to each shared carrier is information indicating that the terminal of the new first type service is not allowed to access under the condition that the load parameter of each shared carrier is greater than or equal to the load parameter threshold.
For example, if there are shared carriers respectively belonging to operator a and operator B under the shared base station, Load _ Parameter [ a ] is greater than or equal to the relative Load Parameter Threshold Load _ Parameter _ Threshold, and 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 access of the new first type of service (e.g., URLLC) is not allowed.
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 of the load parameters of the shared carriers, and determines that the access indication information corresponding to the shared carrier corresponding to the minimum value is information indicating that a terminal of the new first type service is allowed to access, and the access indication information of the shared carriers other than the shared carrier corresponding to the minimum value is information indicating that a terminal of the new first type service is not allowed to access.
For example, 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 ], then the Load of the shared carrier of operator a is lighter, the access indication information corresponding to the shared carrier of operator a is information indicating that a terminal of the new first type of service (e.g., URLLC) is allowed to access, and the access indication information corresponding to the shared carrier of operator B is information indicating that a terminal of the new first type of service is not allowed to access. Correspondingly, if Load _ Parameter [ a ] > Load _ Parameter [ B ], the Load of the shared carrier of operator B is lighter, the access indication information corresponding to the shared carrier of operator a is information indicating that the terminal of the new first type service (e.g., URLLC) is not allowed to access, and the access indication information corresponding to the shared carrier of operator B is information indicating that the terminal of the new first type service is 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 equal, the shared base station determines that the access indication information corresponding to each shared carrier is information indicating that a terminal of a new first type service is allowed to access.
For example, Load _ Parameter [ a ] and Load _ Parameter [ B ] are both smaller than Load _ Parameter _ Threshold, and Load _ Parameter [ a ] is equal to Load _ Parameter [ B ], then the access indication information corresponding to each shared carrier is information indicating that a terminal of a new first type of service (e.g., URLLC) is allowed to access.
The method of the above embodiment is also applicable to the case where there are shared carriers belonging to more than two operators in the 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 a Spare bit (Spare) of a MIB (Main Information Block) corresponding to the shared carrier; and the shared base station broadcasts the corresponding MIB on each shared carrier. For example, 1bit is added to the Spare field of the MIB to indicate access indication information. For example, 1 indicates Barred (no access is allowed for terminals of the first type of service), and 0 indicates notgarred (access is allowed for terminals of the first type of service), which is 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 service is allowed to access. That is, after the shared carrier base station is started and initialized, the broadcast information sent on each shared carrier for the first time indicates that a new terminal of the first type service is allowed to access.
Step S108 may also be included after step S106.
In step S108, the terminals of the first type service receive the broadcast information transmitted on each shared carrier.
Due to the shared carrier, the terminals of different operators can receive the 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 further, when the terminal of the first type service needs to perform cell reselection (e.g., INACTIVE state terminal) or handover (e.g., CONNECTED state terminal), select the shared carrier (cell) in combination with the access indication information in the broadcast information. For example, according to the existing cell reselection standard, a URLLC terminal residing in a shared carrier of operator a may reselect to a shared carrier of operator B, but a Spare field in the MIB of the shared carrier of operator B indicates Barred, and then the URLLC terminal does not reselect to the shared carrier of operator B.
For cell reselection or cell handover of the terminal with the second type of service, reference may be made to the prior art, and details thereof are not described herein.
In the scheme of the above embodiment, the shared base station periodically obtains terminal information on each shared carrier respectively belonging to different operators, where the terminal information includes the state of the terminal of the first type of service and the number of terminals in each state, and the state of the terminal of the second type of service and the number of terminals in each state; and then determining whether each shared carrier allows the terminal of the new first type service to access or not according to the terminal information of each shared carrier, and generating corresponding access indication information. And the shared base station sends the access indication information corresponding to each shared carrier to the terminal through broadcast information so as to guide the access of the terminal of the first type service on each shared 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 terminal in the first type of service can select a proper shared carrier for migration and access, excessive resource occupation by the terminals in different types of services is avoided, access delay of the terminal in the first type of service is reduced, the utilization rate of network resources is improved, and the service quality and the user experience are improved.
Some application examples of the present disclosure are described below with reference to fig. 2, where a shared carrier (cell) belonging to an operator a and a shared carrier (cell) belonging to an operator B are located under a shared base station, the first type of service is a URLLC service, the second type of service is an eMBB service, and each state includes a connected state and an inactive state.
In step S202, the SA-sharing base station is powered on and initialized, and MIB- > URLLC-Barred ═ notBarred (indicating that the access indication information is to allow access of terminals of URLLC). The shared base station can start the generalized load analyzer to execute the subsequent process after being started.
In step S204, the numbers 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 are obtained.
In step S206, load parameters corresponding to the shared carriers (cells) respectively belonging to the operator a and the operator B are determined.
Load parameters Load _ Parameter [ a ] and Load _ Parameter [ B ] corresponding to the shared carriers (cells) belonging to operator a and operator B may be calculated according to the formula of the foregoing embodiment.
In step S208, it is determined whether both Load _ Parameter [ A ] and Load _ Parameter [ B ] are greater than or equal to Load _ Parameter _ Threadhold, and if so, step S210 is performed, otherwise, step S212 is performed.
In step S210, NR broadcast messages MIB- > URLLC-Barred of shared carriers (cells) respectively belonging to operator a and operator B.
In step S212, it is determined whether Load _ Parameter [ A ] is smaller than Load _ Parameter [ B ]. If so, step S214 is performed, otherwise step S216 is performed.
In step S214, the NR broadcast message MIB- > URLLC-Barred of the shared carrier belonging to operator a and the NR broadcast message MIB- > URLLC-Barred of the shared carrier belonging to operator B are transmitted.
In step S216, it is determined whether Load _ Parameter [ A ] is equal to Load _ Parameter [ B ]. If so, step S218 is performed, otherwise step S220 is performed.
In step S218, NR broadcast messages MIB- > URLLC-Barred ═ notBarred attributed to the shared carriers (cells) of operator a and operator B, respectively.
In step S220, the NR broadcast message MIB- > URLLC-Barred of the shared carrier belonging to operator a and the NR broadcast message MIB- > URLLC-Barred of the shared carrier belonging to operator B are transmitted.
Steps S204 to S220 are periodically and repeatedly performed.
The method is applied to a scene that URLLC service and eMMC service are mixed together in a shared co-construction network, and the SA shared base station obtains the load condition by comprehensively considering the number of terminals in the CONNECTED and INACITIVE states of eMMC and URLLC in each shared carrier belonging to different operators, so that the relative load of each shared carrier is analyzed, and the aim of adjusting the policy of the reselection or switching of the URLLC terminal in real time is fulfilled. The load instant weight change condition of each shared carrier can be predicted in advance, URLLC user access is effectively controlled, the URLLC terminal preferentially resides in the optimal carrier, RRC connection is initiated at the frequency point at any time, monitoring, waiting and switching related to load balancing are reduced, access delay is reduced, and normal access and real-time responsiveness of the eMBB terminal are guaranteed; the eMBB and URLLC user experience under the 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. Moreover, the completeness of the SA shared carrier technical scheme is improved, the cost of network establishment, operation and maintenance and service development is reduced, and the flexibility, robustness, compatibility and robustness of the system are improved; the existing system is modified a little, the complexity of realization is low, and the system realization and the scheme popularization are easy.
