Problems solved by technology
Although the use of 5MHz networking solves the problem of insufficient spectrum, as the spectrum of the GSM system narrows, the inter-system interference between the GSM system and the UMTS system increases significantly
Since the UMTS system is a code division system, its air interface signals are continuous in time, so the UMTS system causes very serious and continuous co-channel interference to all time slots of the GSM system, resulting in serious deterioration of the network quality of the GSM system

The embodiment of the invention provides a method for performing business frame transmission and a device thereof. The method comprises the steps that universal mobile telecommunications system UMTS network equipment determines a first time period, and the first time period is used for representing the time period of performing slow associated control channel SACCH frame transmission of global system for mobile communication GSM network equipment by using a first band; the UMTS network equipment determines a second time period according to the first time period, and at least one moment of the first time period is not included in the second time period; and the UMTS network equipment performs UMTS network equipment business frame transmission in the second time period by using the first band. According to the method for performing business frame transmission and the device thereof, the SACCH frame receiving success rate of the GSM network equipment can be enhanced and the interference of the UMTS system on the GSM system can be reduced.
Description
technical field [0001] The embodiments of the present invention relate to the field of communications, and more specifically, to a method and device for transmitting service frames in the field of communications. Background technique [0002] With the development of wireless communication, users' demand for data services has further increased, and the spectrum reallocation of the Global System for Mobile Communication (GSM for short) system is increasing, and the bandwidth of GSM is getting narrower and narrower. There is also an increasing demand for a Universal Mobile Telecommunications System ("UMTS" for short) system. Since the GSM system requires at least 2.4MHz bandwidth, and the UMTS system requires at least 5MHz bandwidth, the problem of insufficient frequency spectrum of many operators is further presented. [0003] In the prior art, the GSM system and the UMTS system use 5 MHz for networking, and the GSM system and the UMTS system directly use the same frequency d...
