技术领域technical field
本发明涉及通信技术领域，尤其涉及一种LTE频段选择方法及设备。The present invention relates to the field of communication technologies, in particular to a method and equipment for selecting an LTE frequency band.
背景技术Background technique
随着通信技术的发展，LTE(Long Term Evolution，长期演进)的应用越来越广泛，LTE技术可以被归类为4G网络技术，而在LTE技术应用的初期，语音通话还需要回退到2G或3G网络来进行，直到VoLTE(Voice over LTE，基于LTE的语音)技术的出现，才使得利用LTE进行语音通话成为现实。在终端设备中除了可以利用LTE网络外，终端设备往往还具有WIFI功能，用户同样可以接入WIFI网络从而实现数据传输。一般2.4G的WIFI的频段范围为2403-2481MHz，由于WIFI的频段和LTE的部分频段比较接近，而通过终端设备基带配置的滤波器进行带外抑制很难达到十分理想的控制相邻频带间干扰的效果，因此，若用户想要使用LTE网络进行语音通话，同时利用WIFI网络进行上网等活动时，会造成两种信号相互干扰而影响通信的质量。With the development of communication technology, LTE (Long Term Evolution, long-term evolution) is more and more widely used. LTE technology can be classified as 4G network technology. In the early stage of LTE technology application, voice calls need to fall back to 2G Or 3G network, until the emergence of VoLTE (Voice over LTE, Voice over LTE) technology, it is not possible to use LTE for voice calls. In addition to using the LTE network in the terminal device, the terminal device often also has a WIFI function, and the user can also access the WIFI network to realize data transmission. Generally, the frequency range of 2.4G WIFI is 2403-2481MHz. Since the frequency band of WIFI is relatively close to some frequency bands of LTE, it is difficult to achieve ideal control of interference between adjacent frequency bands through out-of-band suppression through the filter configured in the baseband of the terminal equipment. Therefore, if the user wants to use the LTE network for voice calls and at the same time use the WIFI network for activities such as surfing the Internet, the two signals will interfere with each other and affect the communication quality.

Each will be described in detail below.
请参阅图1，图1是本发明实施例公开的一种LTE频段选择方法的流程示意图。其中，图1所示的LTE频段选择方法可以包括以下步骤：Please refer to FIG. 1 . FIG. 1 is a schematic flowchart of a method for selecting an LTE frequency band disclosed in an embodiment of the present invention. Wherein, the LTE frequency band selection method shown in Figure 1 may include the following steps:
101、确定终端设备是否需要同时使用无线保真WIFI功能和长期演进LTE功能。101. Determine whether the terminal device needs to use the Wireless Fidelity WIFI function and the Long Term Evolution LTE function at the same time.
本发明实施例中，终端设备可为智能手机、智能手表、掌上电脑、平板电脑、个人数字助理(Personal Digital Assistant，PDA)、销售终端(Point of Sales，POS)等，本发明实施例后续不作复述。In the embodiment of the present invention, the terminal device may be a smart phone, a smart watch, a handheld computer, a tablet computer, a personal digital assistant (Personal Digital Assistant, PDA), a sales terminal (Point of Sales, POS), etc. repeat.
本发明实施例中，终端设备除了具有WIFI功能外，还可以利用LTE网络实现数据传输或VoLTE语音业务。因而，上述同时使用WIFI功能和LTE功能，可能包括两种情况：第一种情况是，终端设备利用LTE进行语音通话，利用WIFI进行数据传输；或者，终端设备将LTE信号转换为WIFI信号，以供需要WIFI信号接入的终端设备利用转换得到的上述WIFI信号进行数据传输。In the embodiment of the present invention, in addition to the WIFI function, the terminal device can also use the LTE network to implement data transmission or VoLTE voice service. Therefore, the simultaneous use of the WIFI function and the LTE function mentioned above may include two situations: the first situation is that the terminal device uses LTE for voice calls and WIFI for data transmission; or, the terminal device converts LTE signals into WIFI signals. The converted WIFI signal is used for data transmission by terminal equipment that needs WIFI signal access.
102、若是，则获取终端设备当前支持的LTE频段集。102. If yes, acquire the LTE frequency band set currently supported by the terminal device.
本发明实施例中，终端设备当前支持的LTE频段集，受终端设备的射频硬件的支持能力和终端设备当前注册的运营商所支持的LTE频段集共同决定。因此，作为一种可选的实施方式，获取终端设备当前支持的LTE频段集的方式可为：获取终端设备当前注册的运营商所支持的LTE的第一频段集；获取终端设备的射频硬件所支持的LTE的第二频段集；将上述第一频段集和上述第二频段集中均包括的频段确定为终端设备当前支持的LTE频段集。In the embodiment of the present invention, the LTE frequency band set currently supported by the terminal device is jointly determined by the support capability of the radio frequency hardware of the terminal device and the LTE frequency band set supported by the operator currently registered by the terminal device. Therefore, as an optional implementation manner, the way to obtain the LTE frequency band set currently supported by the terminal device may be: obtain the first LTE frequency band set supported by the operator currently registered by the terminal device; A second frequency band set of LTE supported: determining the frequency bands included in both the first frequency band set and the second frequency band set as the LTE frequency band set currently supported by the terminal device.
103、从终端设备当前支持的LTE频段集中选取远离WIFI频段的第一频段以进行LTE数据传输。103. Select a first frequency band away from the WIFI frequency band from the LTE frequency bands currently supported by the terminal device to perform LTE data transmission.
根据3GPP组织的规定，WIFI业务可以涵盖的频段主要有2.4G频段和5G频段两种，目前WIFI业务常用的频段为2.4G频段，其频率范围为2403-2481MHz。而在LTE的可用频段中，B40频段的频率范围为2300-2400MHz。WIFI主要应用于室内场合，基于在室内合理位置配置接入点AP来为用户提供无线网络接入服务。而在LTE业务中，B40频段作为在原有频段基础上，为增强室内信号覆盖而做的增补，其应用的范围也为室内分布。而由上述列举的二者的频率范围可知，B40频段的上边带与WIFI的2.4G频段的下边带间缺乏合理宽度的带间隔断，外加其应用位置均在室内环境，因而在实际的用户应用场景中，这两者的信号很容易产生带间干扰而降低通信质量。According to the regulations of the 3GPP organization, the frequency bands that WIFI services can cover mainly include 2.4G frequency band and 5G frequency band. At present, the frequency band commonly used by WIFI services is the 2.4G frequency band, and its frequency range is 2403-2481MHz. In the available frequency band of LTE, the frequency range of the B40 frequency band is 2300-2400MHz. WIFI is mainly used in indoor occasions, and provides users with wireless network access services based on configuring access points (APs) at reasonable indoor locations. In the LTE service, the B40 frequency band is used as a supplement to enhance indoor signal coverage on the basis of the original frequency band, and its application range is also for indoor distribution. From the frequency ranges of the two listed above, it can be seen that there is no reasonable bandwidth between the upper sideband of the B40 frequency band and the lower sideband of the 2.4G frequency band of WIFI, and its application location is in the indoor environment, so in actual user applications In the scenario, the signals of the two are likely to generate inter-band interference and degrade the communication quality.
因而，在本发明实施例中，在需要同时应用WIFI功能和LTE功能时，应当从终端设备当前支持的LTE频段集中排除B40频段，选取其他频段作为上述第一频段以进行LTE数据传输。Therefore, in the embodiment of the present invention, when the WIFI function and the LTE function need to be applied at the same time, the B40 frequency band should be excluded from the LTE frequency band currently supported by the terminal device, and other frequency bands should be selected as the above-mentioned first frequency band for LTE data transmission.
作为一种可选的实施方式，若终端设备采用的运行商网络为移动的话，当前该终端设备支持的LTE频率集为：B38、B39、B40以及B41，则排除B40频段，当前该终端设备可以选择B38、B39或B41频段作为上述第一频段进行接入。As an optional implementation, if the operator network adopted by the terminal equipment is mobile, the current LTE frequency set supported by the terminal equipment is: B38, B39, B40, and B41, and the B40 frequency band is excluded, and the current terminal equipment can Select the B38, B39 or B41 frequency band as the above-mentioned first frequency band for access.
作为一种可选的实施方式，若终端设备采用的运行商网络为联通的话，当前该终端设备支持的LTE频率集为：B1、B3、B8、B40以及B41，则排除B40频段，当前该终端设备可以选择B1、B3、B8或B41频段作为上述第一频段进行接入。As an optional implementation, if the operator network adopted by the terminal equipment is China Unicom, the current LTE frequency set supported by the terminal equipment is: B1, B3, B8, B40 and B41, and the B40 frequency band is excluded. The device may select the B1, B3, B8 or B41 frequency band as the above-mentioned first frequency band for access.
作为一种可选的实施方式，若终端设备采用的运行商网络为电信的话，当前该终端设备支持的LTE频率集为：B1、B3、B5、B40以及B41，则排除B40频段，当前该终端设备可以选择B1、B3、B5或B41频段作为上述第一频段进行接入。As an optional implementation, if the operator network adopted by the terminal equipment is Telecom, the LTE frequency sets currently supported by the terminal equipment are: B1, B3, B5, B40, and B41, and the B40 frequency band is excluded. The device may select frequency band B1, B3, B5 or B41 as the first frequency band to access.
由此可见，实施图1所描述的方法，在终端设备同时使用WIFI功能和LTE功能时，通过使LTE选择远离WIFI频带的第一频带进行通信的方法，可以避免WIFI信号和LTE信号间产生带间干扰，从而提高通信质量。It can be seen that, implementing the method described in FIG. 1, when the terminal equipment uses the WIFI function and the LTE function at the same time, by making LTE select the first frequency band away from the WIFI frequency band for communication, it is possible to avoid the generation of bands between the WIFI signal and the LTE signal. Interference, thereby improving communication quality.
请参阅图2，图2是本发明实施例公开的另一种LTE频段选择方法的流程示意图。如图2所示，该方法可以包括以下步骤：Please refer to FIG. 2 . FIG. 2 is a schematic flowchart of another LTE frequency band selection method disclosed in an embodiment of the present invention. As shown in Figure 2, the method may include the following steps:
201、确定终端设备是否需要同时使用无线保真WIFI功能和长期演进LTE功能。201. Determine whether the terminal device needs to use the Wireless Fidelity WIFI function and the Long Term Evolution LTE function at the same time.
本发明实施例中，上述同时使用WIFI功能和LTE功能，可能包括两种情况：第一种情况是，终端设备利用LTE进行语音通话，利用WIFI进行数据传输；或者，终端设备将LTE信号转换为WIFI信号，以供需要WIFI信号接入的终端设备利用转换得到的上述WIFI信号进行数据传输。In the embodiment of the present invention, the simultaneous use of the WIFI function and the LTE function may include two cases: the first case is that the terminal device uses LTE for voice calls and WIFI for data transmission; or, the terminal device converts the LTE signal into The WIFI signal is used for terminal equipment that needs WIFI signal access to use the converted WIFI signal to perform data transmission.
202、若是，则获取终端设备当前支持的LTE频段集。202. If yes, acquire the LTE frequency band set currently supported by the terminal device.
作为一种可选的实施方式，获取终端设备当前支持的LTE频段集的方式可为：获取终端设备当前注册的运营商所支持的LTE的第一频段集；获取终端设备的射频硬件所支持的LTE的第二频段集；将上述第一频段集和上述第二频段集中均包括的频段确定为终端设备当前支持的LTE频段集。As an optional implementation, the way to obtain the LTE frequency band set currently supported by the terminal device can be: obtain the first LTE frequency band set supported by the operator currently registered by the terminal device; obtain the LTE frequency band set supported by the radio frequency hardware of the terminal device; A second frequency band set for LTE: determining the frequency bands included in both the first frequency band set and the second frequency band set as the LTE frequency band set currently supported by the terminal device.
203、从终端设备当前支持的LTE频段集中选取远离WIFI频段的第一频段以进行LTE数据传输。203. Select a first frequency band away from the WIFI frequency band from the LTE frequency bands currently supported by the terminal device to perform LTE data transmission.
目前WIFI业务常用的频段为2.4G频段，其频率范围为2403-2481MHz。而在LTE的可用频段中，B40频段的频率范围为2300-2400MHz。而由上述列举的二者的频率范围可知，B40频段的上边带与WIFI的2.4G频段的下边带间缺乏合理宽度的带间隔断，外加其应用位置均在室内环境，因而在实际的用户应用场景中，这两者的信号很容易产生带间干扰而降低通信质量。因此，LTE业务应当选择终端设备当前支持的除B40频段以外的频段来进行。At present, the commonly used frequency band for WIFI services is the 2.4G frequency band, and its frequency range is 2403-2481MHz. In the available frequency band of LTE, the frequency range of the B40 frequency band is 2300-2400MHz. From the frequency ranges of the two listed above, it can be seen that there is no reasonable bandwidth between the upper sideband of the B40 frequency band and the lower sideband of the 2.4G frequency band of WIFI, and its application location is in the indoor environment, so in actual user applications In the scenario, the signals of the two are likely to generate inter-band interference and degrade the communication quality. Therefore, the LTE service should be carried out by selecting a frequency band other than the B40 frequency band currently supported by the terminal device.
除此以外，本发明实施例中，终端设备中预存有历史网络接入记录，当搜索到曾接入过的频段时，优先接入该曾经接入的频段。该频段由于之前曾经成功接入过，因此有较高的概率本次也能接入成功，因而如此选择有助于提高网络接入率，降低网络搜索所耗费的时间。In addition, in the embodiment of the present invention, historical network access records are pre-stored in the terminal device, and when a previously accessed frequency band is searched, the previously accessed frequency band is preferentially accessed. Since this frequency band has been successfully accessed before, there is a high probability that it will also be successfully accessed this time. Therefore, such a selection will help increase the network access rate and reduce the time spent on network search.
204、监测同时使用的上述WIFI功能和上述LTE功能间是否存在干扰。204. Monitor whether there is interference between the above-mentioned WIFI function and the above-mentioned LTE function that are used at the same time.
本发明实施例中，可以通过监测WIFI信号和LTE信号的信号强度和接收灵敏度来判断上述WIFI功能和LTE功能间是否存在干扰。In the embodiment of the present invention, whether there is interference between the WIFI function and the LTE function can be judged by monitoring the signal strength and receiving sensitivity of the WIFI signal and the LTE signal.
205、若是，则通过带宽选择滤波器和/或全频段滤波器，对上述LTE功能和/或上述WIFI功能的射频通道进行滤波处理。205. If yes, perform filtering processing on the radio frequency channel of the above-mentioned LTE function and/or the above-mentioned WIFI function by using a bandwidth selection filter and/or a full-band filter.
本发明实施例中，若WIFI功能与LTE功能间仍存在干扰，则可以根据两种功能的优先度，通过在其射频通道中配置带宽选择滤波器或全频段滤波器，实现对一方的带宽控制，从而保证另一方的通信质量。In the embodiment of the present invention, if there is still interference between the WIFI function and the LTE function, the bandwidth control of one party can be realized by configuring a bandwidth selection filter or a full-band filter in its radio frequency channel according to the priority of the two functions , so as to ensure the communication quality of the other party.
作为一种可选的实施方式，若优先保证LTE功能的数据传输，则在WIFI功能的射频通道中配置带宽选择滤波器，在LTE功能的射频通道中配置全频段滤波器，从而实现对WIFI进行带宽控制，保证LTE数据传输的通信质量。As an optional implementation mode, if the data transmission of the LTE function is guaranteed first, a bandwidth selection filter is configured in the radio frequency channel of the WIFI function, and a full-band filter is configured in the radio frequency channel of the LTE function, so as to implement WIFI. Bandwidth control to ensure the communication quality of LTE data transmission.
由此可见，实施图2所描述的方法，在终端设备同时使用WIFI功能和LTE功能时，通过使LTE选择远离WIFI频带的第一频带进行通信的方法，可以避免WIFI信号和LTE信号间产生带间干扰，从而提高通信质量。除此以外，通过在WIFI功能的射频通道和LTE功能的射频通道中分别配置带宽选择滤波器和全频段滤波器的方法，实现对一方的带宽控制，从而保证另一方的通信质量。It can be seen that, implementing the method described in FIG. 2, when the terminal equipment uses the WIFI function and the LTE function at the same time, by making LTE select the first frequency band away from the WIFI frequency band for communication, it is possible to avoid the generation of bands between the WIFI signal and the LTE signal. Interference, thereby improving communication quality. In addition, by configuring the bandwidth selection filter and the full-band filter in the radio frequency channel of the WIFI function and the radio frequency channel of the LTE function, the bandwidth control of one party is realized, thereby ensuring the communication quality of the other party.

At present, the frequency band commonly used by WIFI services is the 2.4G frequency band, and its frequency range is 2403-2481MHz. In the available frequency band of LTE, the frequency range of the B40 frequency band is 2300-2400MHz. WIFI is mainly used in indoor occasions, and provides users with wireless network access services based on configuring access points (APs) at reasonable indoor locations. In the LTE service, the B40 frequency band is used as a supplement to enhance indoor signal coverage on the basis of the original frequency band, and its application range is also for indoor distribution. From the frequency ranges of the two listed above, it can be seen that there is no reasonable bandwidth between the upper sideband of the B40 frequency band and the lower sideband of the 2.4G frequency band of WIFI, and its application location is in the indoor environment, so in actual user applications In the scenario, the signals of the two are likely to generate inter-band interference and degrade the communication quality.
因而，在本发明实施例中，在需要同时应用WIFI功能和LTE功能时，选择单元303应当从终端设备当前支持的LTE频段集中排除B40频段，选取其他频段作为上述第一频段以进行LTE数据传输。Therefore, in the embodiment of the present invention, when the WIFI function and the LTE function need to be applied at the same time, the selection unit 303 should exclude the B40 frequency band from the LTE frequency band currently supported by the terminal device, and select other frequency bands as the above-mentioned first frequency band for LTE data transmission .
作为一种可选的实施方式，若终端设备采用的运行商网络为移动的话，当前该终端设备支持的LTE频率集为：B38、B39、B40以及B41，则排除B40频段，选择单元303可以选择B38、B39或B41频段作为上述第一频段进行接入。As an optional implementation, if the operator network adopted by the terminal equipment is mobile, the current LTE frequency set supported by the terminal equipment is: B38, B39, B40 and B41, then exclude the B40 frequency band, and the selection unit 303 can select The frequency band B38, B39 or B41 is accessed as the above-mentioned first frequency band.
作为一种可选的实施方式，若终端设备采用的运行商网络为联通的话，当前该终端设备支持的LTE频率集为：B1、B3、B8、B40以及B41，则排除B40频段，选择单元303可以选择B1、B3、B8或B41频段作为上述第一频段进行接入。As an optional implementation, if the carrier network adopted by the terminal equipment is China Unicom, the current LTE frequency set supported by the terminal equipment is: B1, B3, B8, B40 and B41, then exclude the B40 frequency band, the selection unit 303 The frequency band B1, B3, B8 or B41 can be selected as the first frequency band for access.
作为一种可选的实施方式，若终端设备采用的运行商网络为电信的话，当前该终端设备支持的LTE频率集为：B1、B3、B5、B40以及B41，则排除B40频段，选择单元303可以选择B1、B3、B5或B41频段作为上述第一频段进行接入。As an optional implementation, if the carrier network adopted by the terminal equipment is Telecom, the current LTE frequency set supported by the terminal equipment is: B1, B3, B5, B40 and B41, then exclude the B40 frequency band, the selection unit 303 The frequency band B1, B3, B5 or B41 may be selected as the first frequency band for access.
由此可见，利用图3所描述的LTE频段选择设备100，在终端设备同时使用WIFI功能和LTE功能时，通过使LTE选择远离WIFI频带的第一频带进行通信的方法，可以避免WIFI信号和LTE信号间产生带间干扰，从而提高通传质量。It can be seen that, using the LTE frequency band selection device 100 described in FIG. 3 , when the terminal equipment uses both the WIFI function and the LTE function, by making LTE select the first frequency band far away from the WIFI frequency band for communication, the WIFI signal and the LTE frequency band can be avoided.
