Description

LTE wireless network rapid site selection method

Technical Field

The invention relates to a mobile communication technology, in particular to a method for quickly selecting an address of an LTE (Long term evolution) wireless network.

Background

At present, with the continuous development of mobile communication technology, the original base station coverage cannot meet more and more service flow requirements, and on the basis of the original network coverage, the base station is built in stages to improve the network performance, so that the method becomes a main mode of network upgrading; for example, based on the original 2G and/or 3G network, according to the traffic demand of the LTE network, in an area where network upgrade is needed, an LTE base station is newly established in the original 2G and/or 3G network, so that the traffic demand of the LTE network is met.

At present, network planning mainly implements network demand analysis by establishing a user data service traffic model for data traffic, connection number, user number, and the like of 2G and/or 3G base stations in a wireless network coverage area. The method determines the area with the highest traffic as the priority area for upgrading the base station by referring to traffic statistical data such as the traffic of the internet access of 2G and/or 3G users in the coverage area, the connection number of the users and the like.

Network planning is carried out by counting the service volume, so that the flow demand of a user on an LTE network can be met; however, after the LTE wireless network is built, if the user still uses the 2G or 3G terminal without a 4G terminal and a package, the built LTE wireless network cannot be utilized to the maximum. For example, in some areas with dense population and low income, the service of the LTE system is not the service type preferred by the user, but the traffic and the price of the 2G or 3G service meet the requirements of the user, when the traffic of the cell is analyzed, the traffic is often very high, but the traffic requirement of the LTE network is very low, and obviously, the built LTE base station resource cannot be utilized reasonably. Meanwhile, a large number of 3G base stations need capacity expansion every year, a large amount of capacity expansion cost of operators is spent, and when an LTE base station is newly built in the area, a large number of users are transferred to the LTE base station, so that capacity waste after the capacity expansion of the 3G base station is caused.

In summary, in the current LTE wireless network site selection, a simple traffic volume method is used as a reference for establishing an LTE base station, and LTE base station resources related to the network site selection cannot be utilized most reasonably, which affects the development of LTE services.

Detailed Description

The technical solutions in the embodiments of the present invention will be described in detail and clearly with reference to the accompanying drawings. The described embodiments are only some of the embodiments of the present invention.

The technical scheme for solving the technical problems is as follows:

as shown in fig. 1: fig. 1 is a schematic flow chart of a method for implementing fast address selection of an LTE wireless network according to the present invention, as shown in fig. 1, including:

step one, in an LTE wireless network planning area, obtaining base station information and user internet access information of base stations of other systems except for an LTE system within a preset time length.

In this step, the base station information includes mobile data traffic, code resource utilization (3G base station); the user internet information comprises: a user mobile phone number, a terminal unique identifier (IMEI) of a user terminal, uplink flow, downlink flow, start time, end time, internet surfing duration, a Location Area Code (LAC) and a cell number (CI); the other modes except the LTE mode are as follows: 2G, and/or 3G, and/or 4G.

The preset time duration refers to the time duration that stable user internet information can be analyzed through the time duration, and generally, the preset time duration can be taken for one week; of course, the preset duration can be taken in combination with experience according to holidays and regional characteristics.

And step two, analyzing and counting the base station information and the user internet access information of each base station respectively to obtain the mobile data traffic, the code resource utilization rate (3G base station) and the LTE terminal internet access traffic carried by other systems corresponding to each base station.

In this step, analyzing and counting the user internet information, where the user terminal supports the first standard and customizes the internet traffic of the service of the first standard belongs to the conventional technical means of technicians in the field, for example, information about whether the user terminal supports the first standard can be obtained through a terminal unique identifier of the terminal, whether the user customizes the service of the first standard can be inquired according to a mobile phone number of the user, the internet traffic of the user within a preset duration can be determined according to the uplink traffic, the downlink traffic, the start time and the end time, and the traffic of the user terminal generated in each base station can be determined through LAC and CI.

And step three, determining the priority of the base station construction by combining the three conditions, thereby accurately determining the position and the priority order of the LTE base station construction.

In this step, the method for determining the priority of the base station construction by combining three conditions is as follows: setting thresholds of mobile data traffic (recorded as condition 1) and LTE terminal internet traffic (recorded as condition 2) carried by other systems according to the network planning scale, regarding a base station reaching the threshold as a base station meeting corresponding conditions, and regarding a base station of which the code resource utilization rate (recorded as condition 3) in the 3G base station exceeds the capacity expansion standard of an operator as a base station meeting the capacity expansion conditions. The priority which simultaneously meets the three conditions is taken as a first priority; a second priority satisfying conditions 1, 3; satisfying conditions 1,2 as a third priority; a fourth priority satisfying conditions 2, 3; the remaining base stations are taken as the fifth priority. The priority sequence in each priority level is in the order of the mobile data flow of the base station, and the base station construction priority sequence accurate to the station is determined. For example, according to network planning (based on considerations such as cost and revenue), 100 LTE base stations may be established in 1000 3G networks in the first quarter, and according to the method of the present invention, a threshold (the first 120% is recommended as a threshold) of mobile data traffic (condition 1) and LTE terminal internet traffic (condition 2) carried by other systems is determined, so as to determine a base station that meets the condition, and at the same time, determine a 3G station that meets the capacity expansion requirement (condition 3). Taking the three conditions which simultaneously meet the conditions as a first priority; a second priority satisfying conditions 1, 3; satisfying conditions 1,2 as a third priority; a fourth priority satisfying conditions 2, 3; and the rest base stations are used as the standard of the fifth priority, and the large priority of the target base station is determined. And then, according to the priority sequence in each priority, arranging a base station construction priority sequence by a method of taking the mobile data flow of the base station as the sequence, and sequencing the first 100 base stations to construct the LTE base station.

The above examples are to be construed as merely illustrative and not limitative of the remainder of the disclosure.
