Communication systems of different standards share part or all of spectrum resources, which may cause interference on the shared spectrum resources. In the embodiment of the present invention, the two communication systems, Global System For Mobile Communications (GSM for short) and Universal Mobile Telecommunications System (UMTS for short), share spectrum resources as an example to illustrate how to control The uplink interference signal caused by the shared spectrum resources of the communication system. The embodiment of the present invention is described by taking this as an example only for explanation, so as to provide a thorough understanding of the present invention, rather than for limitation. The present invention is also applicable to controlling uplink interference signals generated when two or more different communication systems share spectrum resources, and the communication systems that share spectrum resources are not limited to the GSM communication system and UMTS communication system in the embodiment of the present invention, and can also be applied to any other communication system. For example, a 2G communication system and a 3G communication system, or a GSM communication system and a Long Term Evolution (LTE for short) communication system share spectrum resources.

In order to make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

Figure 1 is a schematic diagram of a method for controlling an uplink interference signal according to an embodiment of the present invention. As shown in Figure 1 , the method for controlling an uplink interference signal according to an embodiment of the present invention includes:

Step 110, when a user equipment (User Equipment, referred to as UE) in the communication system of the first standard initiates an uplink service, determine whether the uplink service will occupy the spectrum resources shared by the communication system of the first standard and the communication system of the second standard;

It can be understood that the spectrum resources occupied by each communication system are known. When the spectrum resources occupied by communication systems of different standards overlap with each other, the overlapping spectrum resources are the communication systems of different standards. shared spectrum resources. Generally, spectrum resources shared by communication systems of different standards can be determined through manual settings.

The first-standard communication system and the second-standard communication system with different standards share spectrum resources. When a UE residing in the first-standard communication system initiates an uplink service, if the first-standard communication system allocates frequency resources for the uplink service If any of them belong to the shared spectrum resource, the communication system of the first standard may determine that the uplink service will occupy the spectrum resource shared by the communication system of the first standard and the communication system of the second standard.

Step 120, if the judgment result is yes, the first standard communication system predicts the time and frequency of the uplink interference signal that the uplink service will generate on the second standard communication system on the shared spectrum resource;

If the judgment result of step 110 is yes, the communication system of the first standard may determine frequency points that the uplink service will occupy at each time point according to its own way of allocating spectrum resources to the UE uplink service. If at a certain moment, the frequency point that the uplink service needs to occupy is a shared spectrum resource, the communication system of the first standard can predict that the uplink service will generate an uplink interference signal to the communication system of the second standard at that moment and the frequency point. Thus, the communication system of the first standard can determine the time and frequency of the uplink interference signal that the uplink service will generate to the communication system of the second standard on the shared spectrum resource.

Step 130, the communication system of the first standard sends the time and frequency of the uplink interference signal to the communication system of the second standard;

In this step, the communication system of the first standard may send the time and frequency of the uplink interference signal obtained in step 120 to the communication system of the second standard before the uplink interference signal occurs. The communication system of the second standard can control the uplink interference signal according to the time and frequency of the uplink interference signal.

In this embodiment, when different communication systems share spectrum resources and it is judged that the uplink service initiated by the UE in the first communication system will occupy the shared spectrum resource, it is predicted that the uplink service initiated by the first communication system will The characteristic time and frequency point of the uplink interference signal generated by the second-standard communication system, and the time and frequency point characteristic data of the uplink interference signal are sent to the second-standard communication system, so that the second-standard communication system can target Control uplink interference signals and improve communication quality.

FIG. 2 is a schematic diagram of a method for controlling an uplink interference signal according to another embodiment of the present invention. As shown in FIG. 2 , the method for controlling an uplink interference signal according to another embodiment of the present invention includes:

Step 210, when the UE in the communication system of the first standard initiates an uplink service, determine whether the uplink service occupies the spectrum resources shared by the communication system of the first standard and the communication system of the second standard;

Specifically, it is assumed that the GSM communication system and the UMTS communication system share spectrum resources, the GSM communication system occupies a frequency band of 890-900 MHZ, and the UMTS communication system occupies a frequency band of 899.6-904.6 MHZ, wherein the frequency band of 899.6-900 MHZ is used jointly by the two communication systems. That is, the GSM communication system and the UMTS communication system share spectrum resources of 899.6-900 MHZ. It can be understood that when different standard communication systems share spectrum resources, one situation may be a multi-mode base station scenario, for example, the case where a GSM module and a UMTS module share a base station. In this case, different standard communication systems may refer to different Standard communication modules, and these modules can exist in the same multi-mode base station. Of course, communication systems of different standards can also be represented by communication equipment of different standards, such as GSM base stations and UMTS base stations. In this case, communication systems of different standards can be understood as communication modules of different standards belonging to different base stations. The embodiment of the present invention is mainly described by using the common base station of communication modules of different standards as an example, but is not limited thereto.

Assuming that a UE in the GSM communication system initiates an uplink service, for example, a UE residing in the GSM communication system transmits uplink data to a base station in the GSM communication system, and in the current call, the frequency resource allocated to the UE by the GSM communication system Including 899.8MHZ, which belongs to the spectrum resources shared by the GSM communication system and the UMTS communication system. In this case, the GSM communication system determines that the UE will transmit uplink data on the spectrum resource shared by the GSM communication system and the UMTS communication system, and the uplink service will occupy the shared spectrum resource.

Step 220, the communication system of the first standard acquires the frequency point allocation set, frame number and frequency hopping parameters of the uplink service;

For example, when a UE initiates an uplink service in the GSM communication system, the base station controller of the GSM communication system will allocate resources for this uplink service, including the frame number (Frame Number, FN) and frequency point occupied by this uplink service. Assign set and hopping parameters. As far as the GSM communication system is concerned, it can be understood that the frequency allocation set, frame number and frequency hopping parameters allocated to this uplink service have been obtained. Of course, the specific acquisition actions can be performed by the base station controller in the GSM communication system. executed, or executed by a base station in the GSM system.

Step 230, the communication system of the first standard predicts the time and frequency of the uplink interference signal that the uplink service will generate to the communication system of the second standard on the shared spectrum resources according to the frequency allocation set, frame number and frequency hopping parameters of the uplink service. point;

For example, when the initial frequency resource allocated by the GSM communication system to the uplink service is 899.8MHZ, the GSM communication system can calculate the required frequency for the uplink service according to the frequency allocation set, frame number and frequency hopping parameters allocated to the uplink service. Frame number and frequency point. When the frequency point to be occupied is in the shared spectrum resource, the uplink service will interfere with other uplink services in the UMTS communication system at the frame number and frequency point.

Specifically, since the frame number that the uplink service will occupy can be determined in the same GSM base station, it is accumulated once every 4.615ms, and when a service starts, the GSM communication system can obtain the frame number used in this service process. frame number. In addition, the GSM communication system can determine which data frame (frame number) will be used in this call according to the calculation method of frequency hopping frequency points in the 3GPP 45.002 protocol through the frequency point allocation set and frequency hopping parameters occupied by this uplink what frequency. By judging whether the frequency point occupied by the uplink service belongs to the shared spectrum resource, it can be predicted which frame number will generate a frequency point that interferes with the UMTS communication system. Then, according to the corresponding relationship between the time and the frame number in the service, the GSM communication system can determine at what time and frequency the uplink service will interfere with the uplink service in the UMTS communication system.

Step 240, the communication system of the first standard sends the time and frequency of the uplink interference signal to the communication system of the second standard;

It can be understood that, in the case where the GSM module and the UMTS module share a base station, the GSM communication system (specifically, the GSM module) can send the time and frequency of the uplink interference signal to the UMTS communication system ( Specifically, it may be a UMTS module). In the case that communication modules of different standards belong to different base stations, the GSM communication system (specifically, the GSM module) can send the time and frequency of the uplink interference signal to the A UMTS communication system (specifically, it may be a UMTS module).

In this embodiment, by obtaining the frequency point allocation set, frame number and frequency hopping parameter of the uplink service, and according to the frequency point allocation set, frame number and frequency hopping parameter of the uplink service, calculate the uplink service on the shared spectrum resource. The frame number and frequency point of the uplink interference signal generated by the two-standard communication system, and accurately predict the time and frequency point of the interference signal generated by the uplink service of the first-standard communication system to the second-standard communication system, so that the second communication system The system can reduce interference more accurately and further improve communication quality.

It can be understood that when the GSM module and the UMTS module share a base station, the sending module can send the time and frequency of the uplink interference signal to the UMTS communication system (specifically, the UMTS module) through a data bus, optical fiber, etc. In the case that the communication modules of different standards belong to different base stations, the sending module can use other methods, such as the private interface set between the GSM communication system (specifically, it can be a GSM module) and the UMTS communication system (specifically, it can be a UMTS module) and so on, and send the time and frequency of the uplink interference signal to the UMTS communication system (specifically, the UMTS module).

In this embodiment, when different communication systems share spectrum resources, and the judging module judges that the uplink services initiated by the UE in the first communication system will occupy the shared spectrum resources, the prediction module predicts the uplink services initiated by the first communication system. The uplink service will generate the time and frequency of the uplink interference signal generated by the second-standard communication system, and the sending module will send the time and frequency of the uplink interference signal to the second-standard communication system, so that the second-standard communication system can target Consistently control uplink interference signals and improve communication quality.
