Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
For the purpose of facilitating an understanding of the embodiments of the present invention, reference will now be made to the following description of specific embodiments, taken in conjunction with the accompanying drawings, which are not intended to limit the embodiments of the invention.
Referring to fig. 1, fig. 1 is a flow chart of a deployment method of a narrowband internet of things according to an embodiment of the present invention. The deployment method of the narrowband Internet of things, provided by the embodiment of the invention, is applied to a base station side and comprises the following steps:
s101: after the narrowband Internet of things is deployed according to the pre-stored target deployment information, when a target period arrives, acquiring the target deployment information and a terminal set corresponding to the base station.
The terminal set is composed of all terminals connected with the base station, and the terminals are User Equipment (UE). When the narrowband Internet of things (NB-LOT) is deployed, the narrowband Internet of things needs to occupy an antenna port in the LTE system when the narrowband Internet of things adopts an in-band configuration mode and the narrowband Internet of things and the LTE system use the same PCI. The base station is pre-stored with a plurality of pieces of deployment information, wherein the base station is pre-stored with deployment information corresponding to the situation that the number of antenna ports of the LTE system is consistent with the number of antenna ports of the narrowband Internet of things, and is pre-stored with deployment information corresponding to the situation that the number of antenna ports of the LTE system is inconsistent with the number of antenna ports of the narrowband Internet of things. The plurality of deployment information includes all deployment situations when the number of antenna ports of the LTE system is consistent with the number of antenna ports of the narrowband internet of things and when the number of antenna ports of the LTE system is inconsistent with the number of antenna ports of the narrowband internet of things, and all deployment situations will be described below, and the embodiment is not described herein. When the narrowband internet of things is deployed, target deployment information can be selected from a plurality of deployment information according to the antenna port number of the narrowband internet of things and the antenna port number of the LTE to deploy the narrowband internet of things, so that the problem that the performance of the LTE system is reduced due to the fact that the antenna port number of the LTE system is reduced for deploying the narrowband internet of things when the antenna port number of the narrowband internet of things is inconsistent with the antenna port number of the LTE is avoided.
In this embodiment, the target deployment information includes: the method comprises the steps of selecting a first port number corresponding to a first port set, a second port number corresponding to a second port set and a port mapping relation between the narrowband Internet of things and the LTE system. The first port set comprises all first antenna ports in the LTE system, and the second port set comprises all second antenna ports in the narrowband Internet of things. The port mapping relationship, that is, in the case of the first antenna port in the LTE system occupied by the narrowband internet of things, for example, when the second port number is 2, the port mapping relationship is 0,1, that is, the narrowband internet of things occupies the first antenna port 0 and the first antenna port 1 in the LTE system.
In this embodiment, the target period is preset, and the step of acquiring the target deployment information and the terminal set corresponding to the base station is executed each time the target period arrives, where the target period may be set according to actual needs, and the embodiment is not specifically limited herein, and the target period may be, for example, 10 minutes, 20 minutes, and the like.
S102: and sending the target deployment information to each terminal in the terminal set, so that each terminal returns the channel quality of each first antenna port in the long-term evolution (LTE) system, and obtaining a channel quality set corresponding to each first antenna port.
After the base station obtains the target deployment information of the narrowband internet of things, in order to determine the channel quality of each first antenna port in the LTE system, the target deployment information is sent to each terminal in the terminal set, the terminal can determine the channel quality of each first antenna port in the LTE system according to the target deployment information, the Cell PCI and the CRS (Cell-Specific Reference Signal, cell specific reference signal) in the narrowband internet of things bandwidth, and each terminal sends the channel quality of each first antenna port in the LTE system to the base station after determining the channel quality of each first antenna port in the LTE system, so that for each first antenna port in the LTE system, the base station can obtain a plurality of channel qualities, the channel qualities form a channel quality set corresponding to the first antenna port, and the number of the channel qualities in the channel quality set is the same as the number of the terminals in the terminal set. When the base station needs to send the target deployment information of the narrowband internet of things to each terminal in the terminal set, the base station sends the target deployment information to each terminal in the terminal set in a broadcast mode.
In this embodiment, in order to reduce the calculation process, after the target deployment information of the narrowband internet of things and the terminal set corresponding to the base station are acquired, the judgment needs to be performed according to the first port number corresponding to the first port set and the second port number corresponding to the second port set in the target deployment information, when the first port number corresponding to the first port set is consistent with the second port number corresponding to the second port set, the step S102 is not required to be executed, and when the next target period arrives, the step of acquiring the target deployment information and the terminal set corresponding to the base station is returned to be executed; and when the first port number corresponding to the first port set is inconsistent with the second port number corresponding to the second port set, executing the step S102.
In order to reduce the overhead of information transfer between the base station and the terminal, in this embodiment, the step S102 specifically includes:
determining target identifiers corresponding to the target deployment information from a first association relationship, wherein the first association relationship comprises a plurality of groups of corresponding relationships between the identifiers and the deployment information;
and sending the target identifier to each terminal in the terminal set, so that each terminal determines target deployment information according to the target identifier and the stored first association relation, and determines the channel quality of each first antenna port in the LTE system according to the target deployment information.
The first association is shown in table 1, and the first association is a correspondence between an identifier and deployment information, which is formed by adopting an enumeration manner, according to the number of antenna ports included in the LTE system and the number of antenna ports included in the narrowband internet of things. Each corresponding relation in the first association relation comprises an identifier, a first port number (the port number of all first antenna ports in the LTE system), and a second port number (the port number of all second antenna ports in the narrowband Internet of things) and a port mapping relation. For example, for the corresponding relation of the identifier 3, the first port number is 4, the second port number is 1, and the narrowband internet of things occupies the first antenna port 0 in the LTE system. Aiming at the corresponding relation of the mark 8, the first port number is 4, the second port number is 2, and the narrowband Internet of things occupies a first antenna port 0 and a first antenna port 1 in the LTE system. It should be noted that, in order to facilitate the terminal to determine the target deployment information of the narrowband internet of things according to the target identifier, before that, the base station sends the first association relationship to each terminal in the terminal set for storage in a broadcast manner. When the terminal receives the target identifier, the target deployment information corresponding to the target identifier can be matched from the first association relation.
TABLE 1 first association relationship

When the terminal receives the target deployment information sent by the base station, for each first antenna port in the LTE system, the terminal may send one channel quality determined in the previous target period to the base station, or may preset a measurement window length, and send a plurality of channel qualities determined in the previous target period to the base station. The length of the measurement window is smaller than the target period, and the length of the measurement window can be set according to actual needs, which is not particularly limited in this embodiment. When the measurement window length is preset, the number of measurement window lengths included in the target period can be determined by the following formula, which is specifically as follows:
