The embodiments of the present invention are further described in detail with reference to the accompanying drawings, in which FIG. An exhaustive example. And in the case of no conflict, the features in the embodiments and the embodiments in the description can be combined with each other.

The inventor noticed during the invention that when multiple modems are working simultaneously, there may be severe interference so that communication cannot be completed.

In view of the above insufficiency, the present invention provides a modem control method capable of properly controlling the change of the communication state and/or the communication state of other modems according to the current communication state of other modems when the communication state of a modem needs to be changed. Make each modem not subject to serious interference due to communication band correlation.

In order to facilitate the implementation of the present invention, the following description will be made by way of examples.

Embodiment 1:

1 is a schematic flow chart of a modem control method according to Embodiment 1 of the present invention. As shown in FIG. 1, the modem control method includes:

Step 101: Acquire communication state change information of the first modem, where the communication state is changed. The information includes information of a new frequency band after the change of the first modem;

Step 102: Determine communication state information of the second modem, where the communication state information includes information about a current frequency band of the second modem.

Step 103: Control a communication state change of the first modem according to the interference condition of the new frequency band and the current frequency band, and/or control a communication state of the second modem.

In step 101, the control program acquires communication state change information of the first modem, and the communication state change information may be a request for communication state change, and is actively sent to the control program by the first modem; or may be after the first modem communication state is changed. The notification information sent to the control program; or the information acquired by the control program after actively detecting the change of the communication state of the first modem.

The communication state change information of the first modem includes at least information of a new frequency band requested by the first modem to be changed or changed, and the frequency band information control program can determine the frequency of subsequent operation of the first modem. For example, the frequency band information may be a standard frequency band identifier, such as LTE B8, according to which the frequency range of the subsequent operation of the first modem may be determined. When the state of the first modem will become inoperative, the information of the new frequency band is no frequency band, or it can be understood that the information of the new frequency band is a default value.

In step 102, the control program determines communication state information of the second modem, and the communication state information may be obtained by the control program monitoring the communication state of the second modem in real time after the above step 101; the second modem may also be periodically acquired. The latest information in the communication status information; or the communication status information acquired by the second modem when the self-communication status changes each time, as long as the information is not updated, it is used as the current communication status information of the second modem.

The communication status information of the second modem includes at least information about the current frequency band of the second modem. Similarly, the frequency band information may be a standard frequency band identifier, such as GSM1800. According to the identifier control program, the current second modem works. The frequency range. When the first tune When the modem is currently in the non-working state, the information of the current frequency band is no frequency band, or it may be understood that the information of the current frequency band is a default value.

In step 103, the communication state change of the first modem is controlled according to the interference condition of the new frequency band and the current frequency band.

The interference situation of the new frequency band and the current frequency band may be phase interference or non-phase interference, wherein the phase interference indicates that there is interference between the new frequency band and the current frequency band, which may be mutual interference between frequency bands, or may be a unilateral frequency band. For interference caused by another frequency band, non-phase interference indicates that there is no interference in the new frequency band and the current frequency band, or even if the new frequency band or the current frequency band has some influence on the other party, it is known to those skilled in the art that the degree of influence does not interfere with the communication. According to the interference situation of the new frequency band and the current frequency band, the communication state change of the first modem can be controlled, or the communication state of the second modem can be controlled, or both can be controlled simultaneously to avoid the communication state of the first modem. Changes to the system cause serious interference.

When the frequency band information is no frequency band (or the default value), it indicates that there is no communication service and no interference occurs, so no frequency band (or default value) and any other frequency band are non-interfering frequency bands.

In some embodiments, step 103 specifically includes limiting communication of at least one of the first modem and the second modem when the new frequency band and the current frequency band are mutually interfered frequency bands.

For the case where the new frequency band interferes with the current frequency band, the new frequency band may be the same as the current frequency band, the adjacent frequency band, the frequency center of the frequency band may have a multiple relationship or other various phase interference situations, and the first modem and the second modem are in these cases. There will be a variety of relatively serious disturbances. In this case, any one or all of the following control modes can be performed:

a) limiting the communication state change of the first modem;

b) limiting the communication of the second modem.

The control program may execute a to limit the communication state change of the first modem, which may be to limit the change of its state, for example, when the first modem initiates a data service communication, The communication request may be blocked or its data communication service disabled; the restriction may also be a limitation on the modem itself, such as reducing the transmit power of the first modem by a certain amount or ratio. This approach can avoid or reduce severe interference introduced by changes in the communication state of the first modem and relatively secure communication with the second modem.

The control program may also execute b to limit the communication of the second modem, the same restriction may be to limit its communication, such as blocking communication of the second modem, ie, stopping its current communication service; the limitation may also be The limitations of the modem itself, such as reducing the transmit power of the first modem by a certain amount or ratio. In the mode b, the change of the communication state of the first modem can be allowed, that is, the change of the communication state is not blocked. This approach can also avoid or reduce severe interference introduced by changes in the communication state of the first modem and relatively secure communication with the first modem.

The control program can perform a and b simultaneously, that is, restricting the change of the communication state of the first modem and the communication of the second modem, for example, simultaneously reducing the transmission powers of the first modem and the second modem. This way it is possible to reduce the severe interference introduced by the change in the communication state of the first modem and at the same time to guarantee the basic communication functions of the first modem and the second modem.

In some embodiments, the communication of the first modem or the second modem is blocked when the new frequency band and the current frequency band are the same frequency band.

When the new frequency band of the first modem is the same as the current frequency band of the second modem, the communication frequency ranges of the two modems will overlap, and only reducing the power of the modem may still not significantly reduce the interference, so in this case, the first modem is blocked or Communication by the second modem to completely eliminate interference between modems.

In some embodiments, the transmit power of at least one of the first modem and the second modem is limited when the new frequency band and the current frequency band are adjacent frequency bands.

When the new frequency band of the first modem and the current frequency band of the second modem are adjacent frequency bands When the difference between the new frequency band and the center frequency of the current frequency band is less than a preset threshold (for example, 40 MHz), reducing the transmission power of a certain modem can significantly reduce the interference without completely blocking the communication of a certain modem, so In this case, the transmission power of the first modem or the second modem can be lowered to reduce interference between modems, and of course, the power of the first modem and the second modem can be simultaneously reduced.

In some embodiments, when the new frequency band and the current frequency band are adjacent frequency bands, at least the first modem and the second modem are restricted according to a neighboring degree of the new frequency band and the current frequency band. The transmit power of a modem.

When the new frequency band and the current frequency band are adjacent frequency bands, the higher the degree of proximity, the higher the interference level and the stricter restrictions on the modem. A plurality of band adjacent thresholds may be set at this time, such as a first threshold and a second threshold, wherein the first threshold is less than the second threshold. When the difference between the center frequency of the new frequency band and the current frequency band is less than the first threshold, the transmission power of the first modem and/or the second modem is decreased by the first limit amount, and the difference between the center frequency of the new frequency band and the current frequency band When the value is greater than the first threshold and less than the second threshold, the transmit power of the first modem and/or the second modem is decreased by the second limit, wherein the first limit is greater than the second limit, which may be a decibel of reduced transmit power The number may also be a ratio of reducing the transmission power, for example, the first limit amount is 20 dBm, and the second limit amount is 10 dBm.

In some embodiments, the communication state change information of the first modem further includes information of a new service after the first modem is changed; the communication state information of the second modem further includes a current service of the second modem. Restricting the communication state change of the first modem when the new frequency band and the current frequency band are mutually interfered frequency bands, and the new service level is lower than the current service level; or When the new frequency band and the current frequency band are phase interference frequency bands, and the new service level is not lower than the current service level, the communication of the second modem is restricted.

The communication state change information of the first modem obtained in step 101 further includes information of a new service requested by the first modem or changed, according to the new service. The information control program is capable of determining the level of service for the subsequent operation of the first modem. For example, the new service may be a voice call service, and for an intelligent mobile terminal, the service level of the voice call service is usually the highest.

The communication status information of the second modem determined in step 102 further includes information about the current service of the second modem, and the information control program according to the current service can determine the service level at which the second modem is currently working. For example, the current service may be a data interaction service. For an intelligent mobile terminal, the service level of the data interaction service is usually lower than the service level of the voice call service.

In step 103, that is, on the basis of the above embodiment, when it is possible to selectively limit the communication state change of the first modem or to restrict the communication of the second modem, it is preferable to restrict the modem having a lower communication service level. For example, when the second modem is performing data interaction service, the first modem initiates a voice call service request, and the frequency bands of the two modems are mutually interfered frequency bands. At this time, since the level of the data interaction service is lower than the voice call service, priority protection is provided. The communication of the first modem, that is, allowing the communication state of the first modem to change, preferentially blocks communication of the second modem or preferentially reduces the transmission power of the second modem. When the second modem is performing data interaction service, for example, the first modem also initiates a data interaction service request, and the frequency bands of the two modems are mutually interfered frequency bands. At this time, although the service levels of the two are the same, the first modem is considered. The communication state change is newly initiated, so that the communication of the first modem can still be preferentially guaranteed, that is, the communication state of the first modem is allowed to be changed, the communication of the second modem is preferentially blocked, or the transmission power of the second modem is preferentially reduced.

In some embodiments, when there is harmonic interference in the new frequency band and the current frequency band, the transmit power of the modem to which the frequency band corresponding to the fundamental frequency belongs in the harmonic interference is limited.

Since the harmonic frequency component of the fundamental wave will interfere with the same harmonic wave frequency, when there is an integer multiple relationship between the new frequency band and the center frequency of the current frequency band, there will be harmonic interference, and the first one can be allowed. When the communication state of the modem is changed, it is judged that the fundamental frequency is the new frequency band. The center frequency is also the center frequency of the current frequency band, and the priority is given to the modem to which the frequency band corresponding to the fundamental frequency belongs. For example, when the first modem requests to communicate in the LTE B8 band, and the second modem is currently communicating in the GSM1800 band, considering that the second harmonic of the LTE B8 may interfere with the GSM1800, the transmit power of the first modem can be reduced. (10dBm) to ensure the normal operation of the second modem.

In some embodiments, when there is intermodulation interference in the new frequency band and the current frequency band, limiting a transmit power of a modem to which a frequency band causing intermodulation interference belongs, and the frequency band causing intermodulation interference is the new frequency band and A frequency band in the current frequency band that interferes with reception of another frequency band signal.

In the communication process of a nonlinear device or a propagation medium, when two or more signals are present, due to the nonlinear action, the combined frequency of the two signals is sometimes equal to or close to the reception frequency of the communication signal and is received and interfered. This interference is the intermodulation interference. In the case of intermodulation interference, if the frequency band of the first modem or the second modem will interfere with the signal reception of the other party, the transmission power of the modem causing the interference is limited. For example, when the first modem requests communication in the GSM DCS band, its transmission frequency is 1730 MHz, and the second modem is currently communicating in the LTE B5 band, its transmission frequency is 840 MHz, considering 1730 MHz-840 MHz=890 MHz, and 890 MHz falls. Entering the receiving frequency range of LTE B5, thus causing second-order intermodulation interference, at which time the control program will allow the communication state of the first modem to change, but reduce the transmit power of the first modem to reduce its reception of the second modem signal. Interference. For example, when the first modem requests communication in the CDMABC1 band, its transmission frequency is 1860MHz, and the second modem is currently communicating in the LTE B3 band, and its transmission frequency is 1780MHz, considering 2*1860-1780MHz=1940MHz, and 1940MHz falls. Into the receiving frequency range of CDMA BC1, thus causing third-order intermodulation interference, at which time the control program will allow the communication state of the first modem to change, and reduce the transmit power of the second modem to reduce its reception of the first modem signal. Interference.

In some embodiments, when the new frequency band and the current frequency band are non-interfering frequency bands, communication restrictions on the first modem and the second modem are released.

When the new frequency band and the current frequency band are not in the interference frequency band, that is, the frequency bands are different, non-adjacent, and there is no integer multiple relationship or other phase interference relationship, the communication state of the first modem is allowed to change, and the first Communication between a modem and the second modem. If the communication of a certain modem has been blocked in the foregoing embodiment, or the transmission power of a certain modem is lowered, when the new frequency band and the current frequency band are no longer relevant, the previous blocking is cancelled or the transmission power of a certain modem is restored.

The present invention provides a modem control method capable of properly controlling the change of the communication state and/or the communication state of other modems according to the current communication state of other modems when the communication state of a modem needs to be changed, so that the modems do not There will be serious interference due to the communication band correlation. The invention can distinguish between the same frequency band, the adjacent frequency band, the presence of harmonic interference or the existence of intermodulation interference when the two frequency bands of the two modems are related, and choose to block communication of a certain modem or reduce the transmission power of a certain modem to reduce Inter-modem interference, and the degree of transmission power reduction can be adjusted according to the degree of adjacent frequency band, and the adaptability is strong; the communication of the modem with relatively low service level can be selected according to the communication service level involved in the two modems, Improve the user experience; at the same time, when there is no interference between modems, the modem can be no longer restricted, and the communication capabilities of each modem can be fully utilized.
