Description

Method and apparatus for allocating channels in a multi-channel wireless communication system

Technical Field

The present invention relates to the field of communications and the internet, and in particular, to a method and apparatus for allocating channels in a multi-channel wireless communication system.

Background

The dual-channel wireless terminal is a device for realizing a cellular network communication technology of 'remote Identity Module (SIM)', and is technically characterized in that: the terminal comprises two communication channels. One channel is used as a service channel to provide network service for users, and the SIM cards used by the channel are not directly inserted into the terminal but are intensively placed on a back-end platform; and the other channel is used as an ignition channel and is a control channel between the rear-end platform and the terminal, and SIM card data interaction is completed. The commercial value is: under the premise that the user does not participate or even does not sense, the functions of card selection, card changing, flow charging and the like are completed, and the mobile phone is on hand and has free global travel.

To achieve "global free travel," a two-channel wireless terminal must have radio frequency hardware that can cover a global network. This is a cost and radio performance challenge for dual channel wireless terminals. In addition, since the "remote SIM" scheme requires automatic network selection and selection of the SIM card of the backend platform, full-system, full-band network searching is necessary. The more complete the system and frequency band of the network searching, the more possible the optimization of the SIM card and the network can be realized.

However, in the prior art, both the service channel and the ignition channel in the dual-channel wireless terminal are fixed, that is, the role and function of each channel are fixed, and since the preferred format and frequency band of different application scenarios are likely to be different, for example, LTE (Long Term Evolution ) + B40 in china is the preferred format and frequency band, and LTE + B12 in the united states, the service channel needs to support all formats and frequency bands in order to cope with various application scenarios. In addition, in the prior art, a service channel is adopted to perform full-system and full-band network searching, the time required by network searching is very long, and the user experience is reduced.

Therefore, the problems of inflexible channel assignment and long network searching time in the prior art need to be solved.

Detailed Description

The embodiments of the present invention disclosed are described below with reference to specific embodiments, and those skilled in the art can understand the advantages and effects of the present invention from the disclosure of the present specification. The invention is capable of other and different embodiments and its several details are capable of modification and various other changes, which can be made in various details within the specification and without departing from the spirit and scope of the invention. The drawings of the present invention are for illustrative purposes only and are not drawn to scale. The following embodiments will further explain the related art of the present invention in detail, but the disclosure is not intended to limit the scope of the present invention.

Fig. 1 is a schematic diagram of a multi-channel wireless communication system, wherein the multi-channel wireless communication system is a wireless network device including a plurality of channel devices. In the present application, the multi-channel wireless communication system may include a terminal such as a smart phone or a tablet computer. For convenience of explanation of the technical principle of the present application, in fig. 1, a multi-channel wireless communication system is a wireless network apparatus including two channel devices, one of which is labeled as channel device a and the other is labeled as channel device B.

The multi-channel wireless communication system can realize the function of remote SIM, namely a channel device (called as an ignition channel device) adopts the built-in SIM card of the multi-channel wireless communication system to realize cellular communication, and then is connected to a back-end platform through the Internet to obtain the SIM card data files in the SIM card pool from the back-end platform. Another tunnel device (referred to as a "traffic tunnel device") connects to the cellular network using the SIM card data file remotely acquired by the firing tunnel device and provides network services to the user.

In fig. 1, there are two SIM cards built in the multi-channel wireless communication system, and the two SIM cards correspond to a channel device a and a channel device B, respectively. The built-in SIM card can be a physical card on hardware, and can also be software-simulated SoftSIM data. It should be noted that the number of the built-in SIM cards in the multi-channel wireless communication system may be one, and the SIM cards are shared by the channel device a and the channel device B, and after determining which channel device is the ignition channel device, the built-in SIM cards are provided for the ignition channel device.

The channel device may be connected to corresponding accessory modules, such as a WIFI (Wireless Fidelity ) module, a bluetooth module, and the like. In fig. 1, two WIFI modules of the multi-channel wireless communication system are respectively connected to a channel device a and a channel device B. It should be noted that the number of the WIFI modules of the multi-channel wireless communication system may be one, and the WIFI modules are shared by the channel device a and the channel device B, and after determining which channel device is a service channel device, the WIFI modules are connected to the service channel device. It should be noted that the WIFI module in fig. 1 is only an example, and those skilled in the art can know that the above description of the WIFI module is also applicable to other accessory modules.

In the embodiment of the present application, each channel device has its own supported standard and frequency band, as shown in fig. 1, the standard and frequency band supported by channel device a are M, N and X, and the standard and frequency band supported by channel device B are M, N and Y. In the present application, the network system includes WCDMA (wideband Code Division Multiple Access), LTE, and other systems, and the frequency band is matched with the network system, for example, for the LTE system, the frequency band may be B1, B39, B40, and the like. The system and the frequency band are in pairs, and if one of the two is different, the system and the frequency band are different. For example, LTE + B1 is one standard and frequency band, and LTE + B39 is another standard and frequency band. In the present application, the selection of the system and the frequency band is not limited.

In this application, the sum of the standard and the frequency band supported by the channel device is a set of preset standards and frequency bands, and the standard and the frequency band supported by the channel device are not completely consistent. The preset system and frequency band set may be all systems and frequency bands worldwide, or may be a system and frequency band supported by one country or region, or may be a set of any determined system and frequency band. For example, in fig. 1, the preset sets of standards and frequency bands are M, N, X and Y, the standards and frequency bands supported by channel device a are M, N and X, the standards and frequency bands supported by channel device B are M, N and Y, and the standards and frequency bands supported by channel device a and channel device B overlap (M and N), but are not completely identical. In addition, the systems and frequency bands supported by channel device a and channel device B may not coincide, for example, the systems and frequency bands supported by channel device a are M and X, and the systems and frequency bands supported by channel device B are N and Y.

The structure of a multi-channel wireless communication system comprising two channel devices has been described above with reference to fig. 1, and on the basis of the above description, the structural composition of a multi-channel wireless communication system comprising three, four or even more channel devices is known to those skilled in the art. For example, for a multi-channel wireless communication system including three channel devices, the sum of the system and the frequency band supported by the channel devices is a set of preset systems and frequency bands, and the systems and the frequency bands supported by the channel devices are not completely consistent, a built-in SIM card is provided for the ignition channel device, an accessory module (e.g., a WIFI module) is connected to a service channel device, and the like, which all belong to the scope covered by the present application.

In the present embodiment, the "firing channel device" and the "traffic channel device" are not fixed to the terminal hardware, but can be dynamically switched. For example, a multi-channel wireless communication system is used at power-on in japan. In a cellular communication network in japan, in addition to the standard and frequency band (M and N) common to both channels, the standard and frequency band X are better able to satisfy the user's demand for internet access. At this time, the channel device a including the standard and the frequency band X is automatically switched to the "traffic channel device", and the channel device B becomes the "firing channel device", and the process of allocating channels in the multichannel wireless communication system will be described below.

The present invention provides a method of allocating channels in a multi-channel wireless communication system. Fig. 2 is a flowchart of a method of allocating channels in a multi-channel wireless communication system according to an embodiment of the present invention. As shown in fig. 2, the method comprises the steps of:

step S201, determining available system and frequency band in current wireless communication network environment.

Generally, when a multi-channel wireless communication system is powered on or enters a new wireless communication network environment, for example, from one country or region to another country or region, the systems and frequency bands available in the two countries and regions are likely not the same, and it is necessary to know the systems and frequency bands available in the current wireless communication network environment. When the multi-channel wireless communication system enters a new wireless communication network environment, the multi-channel wireless communication system receives an indication that the network environment changes, and obtains the available system and frequency band in the current wireless network environment according to the indication.

According to an alternative embodiment, determining the available systems and frequency bands in the current wireless network environment comprises: acquiring a current position; and determining the available system and frequency band in the current wireless network environment according to the preset position and the available system and frequency band comparison table based on the current position.

For example, there are various ways to determine the region in which the multi-channel wireless communication system is used, including but not limited to the following three ways:

(1) and (4) configuring in advance. At the time of product sale or lease, the use region of the multi-channel wireless communication system has been clarified, for example, japan; or, it is known that the user purchases the japanese flow package this time; or the user sets the use region through APP and other ways. Through the several means, the target use region can be known and is configured in the multi-channel wireless communication system in advance;

(2) and automatically acquiring the network information. When the multi-channel wireless communication system tries to connect to a cellular network, the network code can be acquired. Network coding is uniformly distributed and managed by the international organization. Through network coding, the current region of the multi-channel wireless communication system can be determined;

(3) by satellite positioning. The global positioning system such as GPS, Beidou and the like can acquire the position information such as longitude and latitude of the location, and further determine the current region of the multi-channel wireless communication system.

After the position of the multi-channel wireless communication system is determined, the position and the available system and frequency band comparison table are inquired, and the available system and frequency band in the current position can be determined. The position and the available system and frequency band comparison table can be stored in a multi-channel wireless communication system in advance or can be inquired in a background. The position and available system and frequency band comparison table lists the corresponding relationship between the position and the available system and frequency band, for example, "china-LTE & B40", "us-LTE & B12", etc., and if the current position is known as the us, the available system and frequency band is LTE & B12.

According to another alternative embodiment, determining the available systems and frequency bands in the current wireless communication network environment comprises: adopting more than two channel devices to respectively search a part of modes and frequency bands in a preset mode and frequency band set; and determining the available system and frequency band in the current wireless network environment according to the search result related to the system and the frequency band.

For example, in the embodiment shown in fig. 1, the preset sets of standards and bands are M, N, X and Y, the standards and bands supported by channel device a are M, N and X, and the standards and bands supported by channel device B are M, N and Y, then channel device a may search for M, N and X, and channel device B searches for M, N and Y; or, for the overlapped system and frequency band between the channel device a and the channel device B, the overlapped system and frequency band are submitted to one of the channel devices for searching, and the other channel device only searches the remaining frequency band and system, for example, the channel device a can search M, N and X, and the channel device B only searches Y; alternatively, for the overlapped system and frequency band between channel device a and channel device B, the overlapped system and frequency band are handed over to be allocated to two channel devices for searching, and complementary searching is performed, for example, channel device a may search M and X, and channel device B may search N and Y.

It can be seen that the systems and frequency bands searched by the channel device a and the channel device B together form a preset system and frequency band set, and the search mode includes a complementary search. The channel device A and the channel device B respectively and simultaneously search for the network, each channel device does not need to traverse the preset system and frequency band set, and only searches a part of the preset system and frequency band set, so that the network searching time can be reduced.

After the channel device a and the channel device B perform the above search, the system and frequency band search results may be generally used as available systems and frequency bands, for example, according to the embodiment shown in fig. 1, the system and frequency band obtained after the search are M, N and Y, and then M, N and Y are used as available systems and frequency bands.

In addition, there may be many systems and frequency bands obtained by searching, some of the systems and frequency bands may not meet the requirements, and it is not desirable to use the systems and frequency bands that do not meet the requirements as the available systems and frequency bands, because if the systems and frequency bands that do not meet the requirements are used as the available systems and frequency bands, the service channel device and the ignition channel device determined according to the available systems and frequency bands are probably not optimal.

Then, determining the available system and frequency band in the current wireless network environment according to the search result about the system and the frequency band comprises: evaluating the system and the frequency band in the system and frequency band search results respectively according to evaluation factors to obtain respective corresponding evaluation values of the system and the frequency band; and determining the system and the frequency band corresponding to the evaluation value larger than the preset threshold as the available system and frequency band in the current wireless network environment in response to the judgment result that the evaluation value corresponding to the system and the frequency band is larger than the preset threshold.

For example, according to fig. 1, if the standard and the frequency band obtained after the search are M, N, X and Y, and M, N, X and Y are evaluated respectively, there may be various evaluation factors, as long as the evaluation factors related to the user experience can be listed therein, for example, the evaluation factors may include network quality, network cost, network roaming, and the like. These evaluation factors may be weighted according to user preferences, e.g., a user may have a higher requirement on network quality than other evaluation factors, and may have more weight on network quality. In this way, corresponding weights are given to all the evaluation factors, and after multiplying and summing up the evaluation factors and the corresponding weights, evaluation values corresponding to the system and the frequency band, that is, M, N, X and Y, can be obtained.

A threshold may be preset, the evaluation values corresponding to the systems and frequency bands are compared with the preset threshold, and the systems and frequency bands corresponding to the evaluation values larger than the preset threshold are determined as the systems and frequency bands available in the current wireless network environment. For example, after the systems and frequency bands M, N, X and Y are evaluated, if it is known that the evaluation values M, N and Y are greater than the preset threshold, M, N and Y are determined as available systems and frequency bands, and X does not belong to the available systems and frequency bands.

Step S202, determining a preferred list related to the ignition channel system and the frequency band and a preferred list related to the service channel system and the frequency band in the available systems and frequency bands.

According to an optional embodiment, for forming a preferred list related to the system and the frequency band of the ignition channel, after obtaining the available system and frequency band, respectively evaluating the available system and frequency band according to evaluation factors related to the ignition channel, and obtaining first evaluation values corresponding to the system and the frequency band in the available system and frequency band, wherein the evaluation factors related to the ignition channel include network stability, coverage continuity, network delay, network cost and the like. These evaluation factors related to the ignition channel can be weighted according to actual needs, for example, the network stability requirement is higher than other selection factors, and more weight can be given to the network stability. In this way, corresponding weights are given to all the evaluation factors, and after the evaluation factors related to the ignition channel are multiplied by the corresponding weights and summed, first evaluation values corresponding to the system and the frequency band can be obtained. An ignition channel threshold value can be preset, the evaluation values corresponding to the system and the frequency band respectively are compared with the preset ignition channel threshold value, and a preferred list related to the system and the frequency band of the ignition channel is established according to the system and the frequency band corresponding to the evaluation value larger than the preset ignition channel threshold value. For example, the available standards and frequency bands are M, N, X and Y, and after M, N, X and Y are evaluated according to the above evaluation factors related to the ignition channel, M, N, X and Y obtain corresponding evaluation values, such as 0.8, 0.1 and 0, respectively. If the preset ignition channel threshold is 0.2, only the system and the frequency band M belong to the preferred list of the system and the frequency band of the relevant ignition channel, and the system and the frequency band N, X and Y do not belong to. According to another optional embodiment, for forming a preferred list related to the service channel system and the frequency band, after obtaining the available system and the frequency band, respectively evaluating the available system and the frequency band according to evaluation factors related to the service channel, and obtaining second evaluation values corresponding to the system and the frequency band in the available system and the frequency band, wherein the evaluation factors related to the service channel include network quality, network charge, network roaming and the like. These evaluation factors related to the traffic channel may be weighted according to actual needs, for example, the network quality requirement is higher than other selection factors, and more weight may be given to the network quality. In this way, corresponding weights are given to all the evaluation factors, and after the evaluation factors related to the service channel are multiplied by the corresponding weights and summed, second evaluation values corresponding to the system and the frequency band can be obtained. A service channel threshold may be preset, the evaluation values corresponding to the systems and frequency bands may be compared with the preset service channel threshold, and a preferred list related to the systems and frequency bands of the service channel may be formed according to the systems and frequency bands corresponding to the evaluation values greater than the preset service channel threshold. For example, the available systems and frequency bands are M, N, X and Y, and after M, N, X and Y are evaluated according to the above evaluation factors related to the traffic channel, M, N, X and Y obtain corresponding evaluation values, such as 0.5, 0.4, 0.1 and 0, respectively. If the preset service channel threshold is 0.3, only the system and frequency bands M and N belong to the preferred list related to the system and frequency bands of the ignition channel, and the system and frequency bands X and Y do not belong to the preferred list.

According to another alternative embodiment, the system and frequency band may also be artificially selected from available systems and frequency bands to form a preferred list about the system and frequency band of the ignition channel and a preferred list about the system and frequency band of the service channel.

Step S203, comparing the systems and frequency bands supported by the two or more channel devices with the preferred list of the systems and frequency bands of the related ignition channels and the preferred list of the systems and frequency bands of the related service channels, and determining the ignition channel device of the two or more channel devices according to a preset judgment rule.

In the process of determining the ignition channel device, a certain judgment rule is often needed to judge which channel device is more suitable. The judgment rule needs to be set by considering the selection of the ignition channel device and the selection of the service channel device at the same time, so that the characteristics and the advantages of the ignition channel device and the service channel device can be considered after the ignition channel device and the service channel device are determined, and better network experience is provided for users.

In an alternative embodiment, the referee rule may be: after each system and frequency band in the preferred list related to the system and frequency band of the ignition channel respectively obtain a first evaluation value related to the ignition channel, the numerical value related to the ignition channel corresponding to the system and frequency band supported by each channel device can be calculated according to the first evaluation value; and after each system and frequency band in the preferred list of the relevant service channel system and frequency band respectively obtain a second evaluation value relevant to the service channel, the numerical value of the relevant service channel corresponding to the system and frequency band supported by each channel device can be calculated according to the second evaluation value. For example, the preferred lists of the system and the band of the relevant ignition channel are M, N, X and Y, M, N, X and Y respectively obtain first evaluation values of 0.5, 0.3, 0.11 and 0.09 regarding the ignition channel, the system and the band supported by the first channel device are M and X, and the system and the band supported by the second channel device are N and Y, so that the value of the relevant ignition channel corresponding to the system and the band supported by the first channel device is 0.61, and the value of the relevant ignition channel corresponding to the system and the band supported by the second channel device is 0.39. For another example, the preferred lists of the systems and bands of the related service channels are M, N, X and Y, and M, N, X and Y respectively obtain that the second evaluation values related to the service channels are 0.2, 0.5, 0.2 and 0.1, the systems and bands supported by the first channel device are M and X, and the systems and bands supported by the second channel device are N and Y, then the values of the related service channels corresponding to the systems and bands supported by the first channel device are 0.4, and the values of the related service channels corresponding to the systems and bands supported by the second channel device are 0.6.

After calculating the numerical values of the relevant ignition channel and the relevant service channel corresponding to the system and the frequency band supported by each channel device, comparing any two channel devices in the more than two channel devices, and dividing into the following situations:

(1) when the values of the ignition channels are equal and the values of the service channels have the same value, the channel device with the smaller value of the service channel is used as an alternative ignition channel device;

(2) in the case that the value of the ignition-related channel and the value of the service-related channel of one channel device are both greater than or both less than the value of the ignition-related channel and the value of the service-related channel of another channel device, the channel device with the smaller value of the service-related channel is taken as the alternative ignition channel device;

(3) under the condition that the numerical values of the related service channels are equal and the numerical values of the related ignition channels have the same magnitude, the channel device with the larger numerical value of the related ignition channel is taken as an alternative ignition channel device;

(4) in the case that the value of the ignition-related channel of one channel device is greater than that of the ignition-related channel of the other channel device, and the value of the service-related channel is less than that of the service-related channel of the other channel device, the channel device with the greater value of the ignition-related channel is taken as the alternative ignition channel device;

(5) in the case where the value of the relevant firing channel and the value of the relevant service channel of one channel device are both equal to the value of the relevant firing channel and the value of the relevant service channel of the other channel device, either one of the two channel devices is taken as the alternative firing channel device.

After the alternative ignition channel device is determined according to the situation, the alternative ignition channel device is compared with the channel device which is not compared in the two or more channel devices until all the channel devices in the two or more channel devices are compared, and the alternative ignition channel device determined after all the channel devices in the two or more channel devices are compared is used as the ignition channel device.

The above is only one specific implementation manner of the referee rule, and a person skilled in the art can conceive of other implementation manners of the referee rule in light of the above implementation manners, which are all covered by the present application. The purpose of the design of the judgment rule is to give consideration to the characteristics and advantages of the ignition channel device and the service channel device and provide better network service experience for users.

And step S204, determining the channel devices except the ignition channel device in the more than two channel devices as service channel devices.

For two channel devices (channel device a and channel device B) of a multi-channel wireless communication system, one channel device (e.g., channel device a) is determined as an ignition channel device, and the other channel device (e.g., channel device B) is determined as a traffic channel device. For more channel devices, one channel device is determined as the firing channel device, and all other channel devices are determined as the traffic channel devices.

In the above description about the method of allocating channels in a multi-channel wireless communication system, the processing flow of two-channel devices is mainly targeted. However, after knowing the process flow of two channel devices, one skilled in the art can think that the process flow for more (e.g., three or four, etc.) channel devices is similar to the process flow for two channel devices, and all fall within the scope covered by the present application.

The ignition channel device needs to be internally provided with a SIM card, and when any channel device is determined to be the ignition channel device, the SIM card internally arranged in the multi-channel wireless communication system needs to be used. Therefore, the SIM card needs to follow the switching of the channels to realize the switching. Thus, according to a specific embodiment, after determining an ignition channel device of a plurality of channel devices of a multi-channel wireless communication system, the method further comprises: a SIM card built in the multi-channel wireless communication system is configured for the firing channel arrangement. Configuring a SIM card built into a multi-channel wireless communication system for ignition channel device use includes several scenarios:

(1) each channel device is preset with an independent SIM card. When the channel device is used as an ignition channel device, the channel device uses a preset SIM card; when the channel device is used as a service channel device, the channel device ignores the preset SIM card and uses a remote SIM card obtained from a back-end platform.

(2) A SIM card is preset, and a plurality of channel devices can be used. And after the ignition channel device is determined, switching to one side of the ignition channel device in a switching mode. As shown in fig. 3, after determining that the pass device B is an ignition pass device, the built-in SIM card is switched to the pass device B. The "handover" may be a hardware-level signal handover or a software-level data forwarding handover.

(3) The multiple channels preset multiple identical Soft SIM data, so-called Soft SIM, means that SIM card entity is not needed, but SIM card content and algorithm are stored in a memory in a data and program mode. As shown in fig. 4, channel device a and channel device B each have their SoftSIM data. When the channel device is used as an ignition channel device, the channel device uses preset SoftSIM data; when the channel device is used as a service channel device, the channel device ignores preset SoftSIM data and uses a remote SIM card acquired from a backend platform.

Besides the cellular communication part, other accessory modules such as a WIFI module and a bluetooth module are also provided in the multi-channel wireless communication system, and are used by the service channel device to provide access services for the user equipment. Therefore, the accessory module (e.g., WIFI module) needs to follow the switching of the channels to implement the switching. Thus, according to another specific embodiment, after determining a traffic channel device of a plurality of channel devices of a multi-channel wireless communication system, the method further comprises: and establishing connection between an accessory module of the multi-channel wireless communication system and the service channel device.
