Description

Technical Field

[0001] The present invention belongs to the field of communication - wireless network optimization, and specifically relates to a service optimization method based on co - construction and sharing. Background Art

[0002] Currently, the co - constructed and shared mobile communication networks mainly include 4G and 5G, with different functional orientations. 4G voice service is the foundation of mobile communication at the present stage. On the premise of ensuring the quality of voice service, the remaining resources are allowed to support data services; 5G is mainly used to carry voice and data services that are currently carried on the 4G network. With the rapid popularization of smart terminals and the rapid development of mobile Internet service applications, data services will continue to show an exponential growth trend, and the network resources consumed by data services will be dozens or even hundreds of times that of voice services.

[0003] Since some 4G frequency bands will gradually be refrequenced to 5G for use, and shared base stations need to serve users of multiple operators, the channel resources occupied by data services during peak hours have begun to cause a decline in the quality of the 4G network, affecting the experience of voice services. At the present stage, mobile voice / data services are mainly carried on the 4G network. The data or voice service offloading rate of the 5G network or some 4G base stations of the same network is not high. The 4G network undertakes too many services, and the network utilization rate is rising continuously, and there is an urgent need to offload traffic to relieve the pressure. Summary of the Invention

[0009] S3: Determine the PRB utilization rates of Operator A's network and Operator B's network according to the PRB usage conditions of Operator A's network and Operator B's network in the shared micro - coverage area;

Description of the drawings

[0019] Figure 1 is a flowchart of the present invention. Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] A traffic optimization method based on co-construction and sharing, as Figure 1 shown, includes:

[0022] S1: For the 4G coverage area without 5G coverage, establish a shared micro-coverage area for the A operator network and the B operator network;

[0023] The A operator network is the network with a higher load, and the B operator network is the network with a lower load;

[0024] S2: Statistically analyze the terminal traffic volume in the shared micro-coverage area, and determine the traffic diversion ratio of the traffic volume of Operator A's network diverted to Operator B's network according to the terminal traffic volume in the shared micro-coverage area;

[0025] The terminal traffic includes: voice traffic and data traffic;

[0026] S3: Determine the PRB utilization rates of Operator A's network and Operator B's network according to the PRB usage conditions of Operator A's network and Operator B's network in the shared micro-coverage area;

[0027] S4: Determine the average RRC connection number according to the RRC connection numbers of Operator A's network and Operator B's network in the shared micro-coverage area;

[0028] S5: Determine the traffic volume optimization strategy for the shared micro-coverage area according to the traffic volume diversion ratio, PRB utilization rate, and average RRC connection number in the shared micro-coverage area;

[0029] S6: For the area covered by both 4G and 5G, establish a shared coverage area for the first network and the second network;

[0030] The first network is the 4G operator network, and the second network is the 5G operator network;

[0031] S7: Determine the traffic volume diversion ratio of the traffic volume of the first network diverted to the second network according to the terminal traffic volume in the shared coverage area, and determine the duration residence ratio of the traffic volume of the first network diverted to the second network according to the terminal traffic residence duration in the shared coverage area;

[0032] S8: Determine the traffic volume optimization strategy for the shared micro-coverage area according to the traffic volume diversion ratio and duration residence ratio in the shared micro-coverage area.

[0033] The establishment of the shared micro-coverage area includes:

[0034] Judge whether the areas under the two networks have the site information of common base stations. If so, set the area with the site information of common base stations as the shared micro-coverage area. If not, set the shared micro-coverage area according to the areas under the network within the set range.

[0035] The traffic volume diversion ratio of the traffic volume of Operator A's network diverted to Operator B's network includes:

[0036] Traffic volume diversion ratio = (Traffic volume of Operator A's users assigned to Operator B's network) / (Traffic volume of Operator A's users assigned to Operator B's network + Traffic volume of the remaining users of Operator A) * 100%;

[0037] When the terminal accesses, it reports its own PLMN to the base station. The shared base station differentiates whether the user is User A or User B through the PLMN when the user accesses. For example, the PLMN of China Unicom is 46001 and that of China Telecom is 46011. When accessing the base station, the base station will separately count the traffic volumes of China Unicom users and China Telecom users through the PLMN.

[0038] The PRB utilization rates of the network of Operator A and the network of Operator B include:

[0039] PRB utilization rate of the network of Operator A = Number of PRBs occupied by the network of Operator A / Number of available PRBs of the network of Operator A;

[0040] PRB utilization rate of the network of Operator B = Number of PRBs occupied by the network of Operator B / Number of available PRBs of the network of Operator B.

[0041] Determining the traffic optimization strategy for the shared micro-coverage area includes:

[0042] By analyzing the traffic splitting ratio, PRB utilization rate, number of RRC connections, and traffic volumes of both networks, comparing relevant index thresholds to specify an optimization plan. When the splitting ratio is less than the index value and the PRB utilization rate of the network of Operator A is greater than the threshold, if the number of RRC connections of the network of Operator A is greater than threshold 1 or the busy-hour traffic volume of the network of Operator A is greater than the threshold and the number of RRC connections of the network of Operator A is greater than threshold 2, then the base station parameters need to be adjusted to increase the splitting ratio; when the splitting ratio is greater than the index value and the PRB utilization rate of the network of Operator B is greater than the threshold, the number of RRC connections of the network of Operator B is greater than threshold 1 or the traffic volume of the network of Operator B is greater than the threshold and the number of RRC connections of the network of Operator B is greater than threshold 2, then the base station parameters need to be adjusted to decrease the splitting ratio.

[0043] The traffic splitting ratio can be adjusted according to traffic requirements. The more traffic that needs to be split, the larger the index value is adjusted. In the 4G area without 5G coverage, the index value is generally set to 60%, and the terminal traffic can be balanced.

[0044] Since the PRB utilization rate needs to handle sudden high-traffic situations, generally, the PRB utilization rate should not exceed 50% as much as possible. For scenarios such as campuses and shopping malls, the base station should generally not exceed 50%. Along high-speed railways and highways, the threshold can be appropriately increased.

[0045] The number of RRC connections is related to traffic. In low-traffic cells, a large number of RRC connections will increase the PRB utilization rate. In high-traffic cells, even though the number of users is small, the use of traffic will also increase the PRB utilization rate.

[0046] Splitting is because the load of a single station is relatively high. Sharing is similar to expanding the base station resources, and splitting the high load to the shared base station with a lower load.

[0047] In this embodiment, when the traffic splitting ratio < 60% and the PRB utilization rate of the Unicom LTE network > 50%, if the number of RRC connections in the Unicom LTE network > 150 or the busy-hour traffic volume of the Unicom LTE network > 8G and the number of RRC connections in the Unicom LTE network > 50, it is necessary to adjust the base station parameters (such as reducing the base station power on the Unicom side, etc.) to increase the traffic splitting ratio; when the traffic splitting ratio > 60% and the PRB utilization rate of the Telecom LTE network > 50%, the number of RRC connections in the Telecom LTE network > 150 or the traffic volume of the Telecom LTE network > 8G and the number of RRC connections in the Telecom LTE network > 50, it is necessary to adjust the base station parameters (such as the inter-frequency handover parameters to increase the handover threshold to the Telecom base station, etc.) to reduce the traffic splitting ratio.

[0048] The traffic splitting ratio of the traffic volume of the first network being split to the second network includes:

[0049] Traffic splitting ratio = Traffic volume split by the second network terminal to the second network / (Traffic volume split by the second network terminal to the second network + Traffic volume of the second network terminal falling back to the first network + Traffic volume generated by the first network terminal in the first network) * 100%.

[0050] The traffic volume of the second network terminal falling back to the first network: The second network level value is lower than -105 db or the terminal falls back to the first network through EPS fallback for voice services.

[0051] The duration residence ratio of the traffic volume of the first network being split to the second network includes:

[0052] Duration residence ratio = Residence duration of the traffic volume split by the second network terminal to the second network / (Residence duration of the traffic volume split by the second network terminal to the second network + Residence duration of the traffic volume of the second network terminal falling back to the first network).

[0053] Determine the traffic volume optimization strategy of the shared micro-coverage area according to the traffic splitting ratio and duration residence ratio of the shared micro-coverage area, including:

[0054] When the traffic splitting ratio is less than the target value and the residence ratio is less than the target value, adjust the base station parameters to increase the traffic splitting ratio and residence ratio; when the traffic splitting ratio is greater than the target value and the residence ratio is less than the target value, it is necessary to cooperate between network and business to increase the residence ratio; when the traffic splitting ratio is greater than the target value and the residence ratio is greater than the target value, the daily traffic volume of the second network cell is greater than the threshold and the PRB utilization rate of the second network is greater than the threshold, it is necessary to reduce and adjust the base station parameters to reduce the network traffic splitting ratio.

[0055] The traffic splitting ratio can be adjusted according to business requirements. The more traffic volume needs to be split, the larger the target value is adjusted. Generally, the target value is set to 50% in the area covered by both 5G and 4G to achieve balanced terminal services.

[0056] Since there is no pressure on the number of RRC accesses in 5G for the time being, it is not considered for the time being. Currently, only traffic volume and PRB utilization rate are considered. Because it is necessary to cope with sudden high traffic situations, the general PRB utilization rate generally does not exceed 50% as much as possible, so that the base station maintains a certain amount of PRB resource backup. According to scenarios such as campuses and shopping malls, it generally does not exceed 50%. For high-speed railways and along highways, the threshold can be appropriately increased.

[0057] In this embodiment, when the traffic splitting ratio < 50% and the residence ratio < 40%, the base station parameters are adjusted to increase the traffic splitting ratio and the residence ratio (such as reducing the minimum access level of 5G or reducing the threshold of the blind redirection A2 event, etc.); when the traffic splitting ratio > 50% and the residence ratio < 40%, network and service coordination is required to increase the residence ratio (such as expanding the market for 5G terminals and package marketing or reminding users to turn on the 5G switch on the terminal, and the network side enables the SA function of 5G terminals to be turned on by default, etc.); when the traffic splitting ratio > 50% and the residence ratio > 40%, the daily traffic volume of the 5G network cell > 170G and the daily average PRB utilization rate of the 5G network cell > 60%, it is necessary to reduce and adjust the base station parameters to reduce the network traffic splitting ratio (such as increasing the minimum access level or adding a new base station for capacity expansion or increasing the threshold of inter-system handover / redirection parameters).

[0058] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
