Embodiment 1

[0051] The flow chart of the present invention is attached figure 1 shown. When a new call arrives, classify the service of the new call, and extract auxiliary information according to the current location information and beam information. The auxiliary information includes the user's geographic location information and beam information. Reading the user's geographic location information can determine the current beam information of the user, and the interference of all channels under the current beam can be judged through the beam information. In this embodiment, calls are mainly divided into three categories, which are voice service, data service and image service respectively. The bit error rate that the voice service can tolerate is higher than that of the image service, so the tolerable interference intensity of the voice service is greater than that of the image service. The tolerable bit error rate of the image service is higher than that of the data service, so the to...

Embodiment 2

[0055] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that this embodiment is a method for avoiding interference to an ongoing call. In the prior art, there are two types of call switching: one is due to the movement of satellites and users The coverage change caused by nature requires the call in normal communication to be switched to the adjacent beam to continue communication; the other is that the channel can no longer support the communicating user for effective transmission due to the change of channel interference, so it needs to be switched to the allowed beam. channel for communication. The former needs to compare it with the call switching threshold according to the signal tracking by the access switching module, and judge whether it needs to switch; the latter needs to obtain the acceptable service category according to the channel interference situation, and judge Whether the channel can continue to maintain the call. In th...

Embodiment 3

[0059] Such as Figure 7 As shown, a device for avoiding interference to a call based on a spectrum map, that is, an electronic device 310 (such as a computer server with a program execution function), which includes at least one processor 311, a power supply 314, and the at least one processing A memory 312 and an input-output interface 313 that are communicatively connected to the device 311; the memory 312 stores instructions that can be executed by the at least one processor 311, and the instructions are executed by the at least one processor 311, so that the at least one A processor 311 can execute the method disclosed in Embodiment 1; the input and output interface 313 can include a display, a keyboard, a mouse, and a USB interface for inputting and outputting data; the power supply 314 is used for providing electric energy for the electronic device 310 .

[0060] Those skilled in the art can understand that all or part of the steps for implementing the above-mentioned m...

Abstract

The invention relates to the field of communication, in particular to a method and a device for carrying out interference avoidance on a call based on a spectrum map, which comprise the following steps of: 1, carrying out service classification on a new call or an ongoing call; and 2, extracting auxiliary information from pre-stored spectrum map data, performing availability classification on channels according to the auxiliary information and the service classification result, and performing interference avoidance on the new call or the ongoing call according to the availability classification result. According to the method, interference avoidance is carried out on the new call or the ongoing call, so that the new call blocking rate, the switching failure rate and the call drop rate of the call can be effectively reduced, and meanwhile, the situation that the accessed call cannot realize correct communication due to serious interference is reduced.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for avoiding interference to calls based on spectrum maps. Background technique [0002] Satellite communication system has always been an important means of communication due to its advantages such as global coverage and not being affected by terrain and terrain. However, for the satellite communication system, except for the geosynchronous earth orbit (Geosynchronous Earth Orbit, GEO) satellite, which is relatively stationary to the ground, the rest of the satellites generally move continuously in the air according to a certain trajectory. In addition, users may also be constantly moving of. Therefore, for an incoming call, it is possible to enter a different satellite coverage area during its communication period. In order to keep the call continuing, it is necessary to switch the call. Therefore, the research on access and switching technology is a s...
