Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and apparatus for activating a frequency band combination, a readable storage medium, and a terminal device.
Background
With The continuous update of The third generation partnership project (The 3rd Generation Partnership Project,3GPP), the dual communication combination required to be supported (E-UTRA-NR Dual Connectivity: dual communication combination of LTE and NR, abbreviated as ENDC combination) is also becoming more and more. In order to support more ENDC combinations, the radio frequency front End (Radio Frequency Front-End, RFFE) scheme is also continuously updated, so that the same device (e.g., radio frequency switch) of the radio frequency front End module is shared by a plurality of frequency bands (bands) of the terminal device, but the special scene of different parameter value configurations is provided for the same switch register.
Currently, a multi-on technology (multi-on) is mainly adopted to realize normal operation when a plurality of frequency bands use the same radio frequency switch. Implementing the multi-on technique requires configuring the ENDC combinations supported by the terminal device and their corresponding activation parameters in a switch register. Specifically, all ENDC combinations supported by the terminal equipment and corresponding activation parameters of each ENDC combination are preconfigured in a switch register; and then directly searching a frequency band combination completely consistent with the current working frequency band combination to be activated from a switch register, and acquiring corresponding activation parameters to activate the working frequency band combination to be activated, thereby controlling the conduction of a corresponding logic channel.
However, the limitations of the above solution are mainly: (1) How many ENDC combinations are supported by the terminal device, how many ENDC combinations are configured in the switch register accordingly, and the activation parameters corresponding to each ENDC combination are also configured. This results in a large occupation of storage space, especially in an application scenario where the number of ENDC combinations supported by the terminal device is very large, which will cause a large occupation of limited storage space and greatly increase hardware costs. (2) With the development of communication technology or application scene update, the number of frequency band combinations will be more and more (for example, there may be hundreds or thousands of ENDC combinations), and if a large number of ENDC combinations and corresponding activation parameters are configured one by one, the configuration cost will be high. (3) In practical application, a situation of adding or deleting a frequency band combination often occurs, and in this situation, not only the frequency band combination needs to be added or deleted, but also a corresponding activation parameter needs to be adaptively added or deleted, which results in greatly reduced configuration efficiency.

Optionally, the traversing the preset plurality of band sets in the switch register to find out whether there is a band set including all the target bands includes: screening out candidate frequency band sets from all frequency band sets preconfigured in the switch register, wherein the candidate frequency band sets are frequency band sets with the number of frequency bands being more than or equal to the number of all target frequency bands; traversing the screened candidate frequency band set to find out whether the candidate frequency band set containing all the target frequency bands exists.

Optionally, each operating frequency band combination supported by the terminal device includes at least two types of frequency bands.
Optionally, the supported working frequency band combination of the terminal device is an ENDC combination in NSA mode, and each working frequency band combination at least includes two types of frequency bands of LTE and NR.
The embodiment of the invention also provides a device for activating the frequency band combination, which comprises the following steps: the system comprises a to-be-activated frequency band determining module, a to-be-activated frequency band determining module and a target frequency band determining module, wherein the to-be-activated frequency band determining module is used for determining a current to-be-activated working frequency band combination of terminal equipment and determining one or more frequency bands contained in the current to-be-activated working frequency band combination, wherein the one or more frequency bands are recorded as target frequency bands; the frequency band searching module is used for traversing a plurality of frequency band sets preconfigured in the switch register to find out whether the frequency band sets containing all the target frequency bands exist, wherein the switch register is preconfigured with the plurality of frequency band sets and an activation parameter set corresponding to each frequency band set, and each frequency band set is a union set of frequency bands of one or more working frequency band combinations supported by the terminal equipment; and the frequency band activating module is used for calling the activating parameters for activating the target frequency band from the activating parameter set corresponding to the searched frequency band set to activate the current working frequency band combination to be activated if the frequency band set containing all the target frequency bands is searched.
The embodiment of the invention also provides a readable storage medium, on which a computer program is stored, which when being executed by a processor performs the steps of the above-mentioned method for activating a combination of frequency bands.
The embodiment of the invention also provides a terminal device, which comprises a memory and a processor, wherein the memory stores a computer program capable of running on the processor, and the processor executes the steps of the activation method of the frequency band combination when running the computer program.
Compared with the prior art, the technical scheme of the embodiment of the invention has the following beneficial effects:
in the embodiment of the invention, the current working frequency band combination to be activated of the terminal equipment is determined, and one or more frequency bands contained in the current working frequency band combination to be activated are determined and recorded as target frequency bands; traversing a plurality of preset frequency band sets in a switch register to find out whether the frequency band sets containing all the target frequency bands exist, wherein the switch register is preconfigured with the plurality of frequency band sets and an activation parameter set corresponding to each frequency band set, and each frequency band set is a union set of frequency bands of one or more working frequency band combinations supported by the terminal equipment; and if the frequency band set containing all the target frequency bands is found, invoking an activation parameter for activating the target frequency bands from an activation parameter set corresponding to the found frequency band set so as to activate the working frequency band combination to be activated currently.
In the prior art, the switch register is used for configuring all working frequency band combinations supported by the terminal equipment and activating parameter combinations corresponding to each working frequency band combination. In other words, how many operating frequency band combinations are supported by the terminal device, how many frequency band combinations are configured in the switch register correspondingly, and the activation parameter combination corresponding to each operating frequency band combination is also configured. Because there are more repeated frequency bands and parameters in different frequency band combinations and corresponding activation parameter combinations, this results in a larger occupation of storage space and an increase in configuration cost and complexity. In contrast, in the embodiment of the present invention, a plurality of frequency band sets and an activation parameter set corresponding to each frequency band set are configured in the switch register. Since each band set is a union of the bands of one or more working band combinations, a large amount of redundant repetitive content can be removed by determining the band union, so that the total number of band sets and corresponding activation parameter sets configured in the switch register is far less than the total number of band combinations and corresponding activation parameter combinations configured in the prior art. Therefore, the accurate activation of the frequency band combination can be realized on the basis of greatly reducing the occupation of the storage space, the configuration cost and the configuration complexity.
Further, one or more iterations are performed on all the working frequency band combinations supported by the terminal equipment according to the sequence of the number of the included frequency bands from large to small, so that the preconfigured multiple frequency band sets are obtained. Specifically, in the first iteration, all working frequency band combinations supported by the terminal equipment are used as first-round frequency band combinations to be processed, and the set of each frequency band contained in the current-round frequency band combinations to be processed with the largest frequency band number is used as a first-round determined frequency band set; in each subsequent iteration, the remaining working frequency band combinations except the subset belonging to the frequency band set determined by each previous iteration are used as the frequency band combinations to be processed of the current iteration, if the maximum frequency band number of each frequency band combination to be processed of the current iteration is greater than 2, the set of each frequency band contained in the frequency band combinations to be processed of the current iteration with the maximum frequency band number is used as the frequency band set determined by the current iteration, the iteration is stopped until the maximum frequency band number of each frequency band combination to be processed of the current iteration is equal to 2, and the set of the frequency bands contained in each frequency band combination to be processed of the current iteration is used as a single frequency band set.
In the embodiment of the invention, the iteration scheme is adopted to determine the plurality of frequency band sets, so that compared with the method that a plurality of working frequency band combinations are randomly selected each time to be combined to obtain the frequency band set, on one hand, the method is favorable for avoiding the problem of missing the working frequency band combinations, and all the repeated frequency bands and corresponding parameters in different working frequency band combinations are combined into a single frequency band and parameters, so that the comprehensiveness of the obtained frequency band set is improved, and the occupied storage space is reduced to the greatest extent; on the other hand, compared with the unordered iteration mode, the method and the device for achieving the multi-frequency band iteration are capable of conducting iteration according to the sequence from large frequency bands to small frequency bands, improving iteration efficiency and achieving more efficient acquisition of the preconfigured multi-frequency band sets.

Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, fig. 1 is a flowchart of a method for activating a frequency band combination according to an embodiment of the present invention. The method can be applied to terminal equipment with a data processing function, including but not limited to mobile phones, tablet computers, intelligent wearable equipment (for example, intelligent watches, intelligent helmets and the like), vehicle-mounted terminal equipment and the like.
The method may include steps S11 to S13:
step S11: determining a current working frequency band combination to be activated of the terminal equipment, and determining one or more frequency bands contained in the current working frequency band combination to be activated, and recording the one or more frequency bands as target frequency bands;
step S12: traversing a plurality of preset frequency band sets in a switch register to find out whether the frequency band sets containing all the target frequency bands exist, wherein the switch register is preconfigured with the plurality of frequency band sets and an activation parameter set corresponding to each frequency band set, and each frequency band set is a union set of frequency bands of one or more working frequency band combinations supported by the terminal equipment;
step S13: and if the frequency band set containing all the target frequency bands is found, invoking an activation parameter for activating the target frequency bands from an activation parameter set corresponding to the found frequency band set so as to activate the working frequency band combination to be activated currently.
In the implementation of step S11, the terminal device may support a plurality of operating frequency band combinations, where each frequency band in each operating frequency band combination supported by the terminal device has one or more preset activation parameters, where the activation parameters are used to activate a corresponding frequency band (i.e. may be used to control conduction of a radio frequency path corresponding to the frequency band). The parameter value of each of the activation parameters may be represented by a predetermined number of bits. In practical application, all the working frequency band combinations supported by the terminal equipment, the corresponding relation between the activation parameters and the frequency bands can be preset when the product leaves the factory. Of course, as the product upgrades or updates, new additions, deletions, updates, etc. may occur to the supported operating band combinations.
In some embodiments, each operating frequency band combination supported by the terminal device comprises at least two types of frequency bands. Wherein, each frequency band type has at least one frequency band, and the frequency bands of different frequency band types can be the same or different.
The supported operating frequency band combinations of the terminal device may be, without limitation, ENDC combinations in NSA mode, and each operating frequency band combination includes at least two types of frequency bands, namely LTE and NR.
For example, a certain ENDC combination may be: lte_band_a, lte_band_b, lte_band_c, nr_band_d, nr_band_e; another ENDC combination may be: lte_band_a, nr_band_d, nr_band_e; another ENDC combination may be: lte_band_a, lte_band_b, lte_band_c, nr_band_a, nr_band_d. Where LTE and NR denote band type identities and A, B, C, D, E denote different bands.
In other embodiments, each operating band combination supported by the terminal device comprises a single type of band. Wherein there are at least two different frequency bands under a single frequency band type.
Further, determining the current to-be-activated working frequency band combination of the terminal device may specifically include: responding to a received working frequency band combination activating signal, and taking the working frequency band combination to be activated indicated by the working frequency band combination activating signal as the working frequency band combination to be activated currently of the terminal equipment; or, in response to receiving the working frequency band combination switching signal, using the to-be-switched frequency band combination indicated by the working frequency band combination switching signal as the working frequency band combination to be activated currently of the terminal equipment.
After determining the current to-be-activated working frequency band combination of the terminal equipment, accurately searching corresponding activation parameters from a switch register to activate the current to-be-activated working frequency band combination. Specifically, the corresponding radio frequency channel of the to-be-activated working frequency band combination is controlled to be conducted (for example, the radio frequency switch is controlled to be switched from an off state to an on state) by calling the searched parameter value of the activation parameter.
In the implementation of step S12, the switch register may be a partial storage area defined in the memory.
It should be noted that, in the conventional art, the switch register is used to configure all the operating frequency band combinations supported by the terminal device, and the corresponding activation parameter combinations of each operating frequency band combination. In other words, how many operating frequency band combinations are supported by the terminal device, how many frequency band combinations are configured in the switch register correspondingly, and the activation parameter combination corresponding to each operating frequency band combination is also configured. Because there are more repeated frequency bands and parameters in different frequency band combinations and corresponding activation parameter combinations, this results in a larger occupation of storage space and an increase in configuration cost and complexity.
In contrast, in the embodiment of the present invention, a plurality of frequency band sets and an activation parameter set corresponding to each frequency band set are configured in the switch register. Since each band set is a union of the bands of one or more working band combinations, a large amount of redundant repetitive content can be removed by determining the band union, so that the total number of band sets and corresponding activation parameter sets configured in the switch register is far less than the total number of band combinations and corresponding activation parameter combinations configured in the prior art. Therefore, the accurate activation of the frequency band combination can be realized on the basis of effectively reducing the occupation of the storage space, the configuration cost and the configuration complexity. Particularly, in the scene that the terminal equipment supports a very large number of combinations of the working frequency bands, the occupation of storage space can be greatly reduced, the configuration cost is reduced, and the configuration operation is simplified.
Further, in the prior art, for the case of adding or deleting the operating frequency band combinations supported by the terminal device (these cases are more common), not only the pre-configured operating frequency band combinations in the switch register need to be added or deleted, but also the corresponding activating parameter combinations need to be adaptively added or deleted, which results in a great improvement of the configuration cost and a reduction of the configuration efficiency.
In contrast, in the embodiment of the present invention, when the new working frequency band combination is added, if the new working frequency band combination is a subset of the configured frequency band set, the new working frequency band combination does not need to be reconfigured, and the activation parameter combination corresponding to the new working frequency band combination does not need to be reconfigured; if the new added working frequency band combination has a new frequency band which does not exist in the configured frequency band set, the new frequency band is only added to the configured frequency band set, and the corresponding activation parameter is added to the configured activation parameter set, so that the new added working frequency band combination and the activation parameter combination thereof do not need to be reconfigured. When deleting the working frequency band combination, as long as the working frequency band combination to be deleted is a subset of the configured frequency band set, no update configuration operation is required to be executed, and the original configuration content is maintained. Therefore, not only can the occupied storage space be reduced, but also the configuration operation can be greatly simplified, and the configuration cost is reduced.
Further, traversing the preset plurality of band sets in the switch register to find out whether there is a band set containing all the target bands, which specifically may include: screening a candidate frequency band set from all frequency band sets preconfigured in the switch register, wherein the candidate frequency band set is a frequency band set with the number of frequency bands being greater than or equal to the number of all the target frequency bands (namely, greater than or equal to the total number of frequency bands contained in the current to-be-activated working frequency band combination); traversing the screened candidate frequency band set to find out whether the candidate frequency band set containing all the target frequency bands exists.
In the embodiment of the invention, the scheme of screening before traversing searching is adopted, so that the number of frequency band sets to be traversed can be reduced, the operation data quantity is reduced, the expenditure of traversing and searching is reduced, and the searching efficiency is improved.
Furthermore, if the total number of frequency bands contained in each frequency band set is smaller than the number of all the target frequency bands from all the frequency band sets preconfigured in the switch register, the combined activation failure signal of the working frequency band can be directly returned.
In the implementation of step S13, if a frequency band set including all the target frequency bands is found, the activation parameters for activating each target frequency band may be determined from the activation parameter sets corresponding to the found frequency band set, and then the activation parameters of each target frequency band are called to implement activation of the current to-be-activated working frequency band combination formed by each target frequency band.
In some embodiments, the number of the frequency band sets that are found and contain all the target frequency bands is greater than or equal to 2; the step S13 may specifically include: determining the number of the activation parameters in the activation parameter set corresponding to each frequency band set; and invoking the activation parameters for activating the target frequency band from the activation parameter set with the minimum number of the activation parameters. Thus, the efficiency of acquiring the activation parameters of the target frequency band can be improved.
In other embodiments, the number of the found frequency band sets including all the target frequency bands is 1, and the activation parameters for activating the target frequency bands may be directly called from the found activation parameter sets corresponding to the frequency band sets.
Further, if the frequency band set containing all the target frequency bands cannot be found, a working frequency band combination activation failure signal can be returned.
Referring to fig. 2, fig. 2 is a partial flowchart of another method for activating a frequency band combination according to an embodiment of the present invention. The activation method of the other frequency band combination may include steps S11 to S13 in fig. 1, and may further include steps S21 to S23, where the steps S21 to S23 may be performed before the step S12.
In step S21, one or more iterations are performed on all the working frequency band combinations supported by the terminal device according to the order of the number of the included frequency bands from large to small, so as to obtain the preconfigured multiple frequency band sets.
In step S22, for each frequency band set, an activation parameter for activating each frequency band in the frequency band set is determined, and an activation parameter set corresponding to the frequency band set is obtained.
In step S23, the obtained frequency band sets and the corresponding activation parameter sets are arranged in the switch register.
In step S21, one or more iterations are performed on all the operating frequency band combinations supported by the terminal device according to the order of the number of the included frequency bands from large to small, including: in the first round of iteration, all working frequency band combinations supported by the terminal equipment are used as first round of frequency band combinations to be processed, and the set of each frequency band contained in the current round of frequency band combinations to be processed with the maximum frequency band number is used as a first round of determined frequency band set; in each subsequent iteration, the remaining working frequency band combinations except the subset belonging to the frequency band set determined by each previous iteration are used as the frequency band combinations to be processed of the current iteration, if the maximum frequency band number of each frequency band combination to be processed of the current iteration is greater than 2, the set of each frequency band contained in the frequency band combinations to be processed of the current iteration with the maximum frequency band number is used as the frequency band set determined by the current iteration, the iteration is stopped until the maximum frequency band number of each frequency band combination to be processed of the current iteration is equal to 2, and the set of the frequency bands contained in each frequency band combination to be processed of the current iteration is used as a single frequency band set.
The above iterative process is described in detail below by way of a non-limiting example. In this example, the total operating frequency band combination supported by the terminal device includes: ENDC combination 1-15.
ENDC combination 1: lte_band_a, lte_band_b, lte_band_c, nr_band_d, nr_band_e;
ENDC combination 2: lte_band_a, lte_band_b, nr_band_d, nr_band_e;

Of the above-described respective ENDC combinations, ENDC combinations 2 to 6 are respectively a subset of ENDC combination 1; the ENDC combinations 8-10 are respectively a subset of ENDC combination 7; the ENDC combinations 12 to 13 are respectively a subset of the ENDC combination 11, and the ENDC combinations 14 and 15 are respectively independent frequency band combinations.
In the first iteration, the 12 ENDC combinations supported by the terminal device are used as first-round to-be-processed frequency band combinations, wherein two to-be-processed frequency band combinations with the largest frequency band number are respectively an ENDC combination 1 and an ENDC combination 7 (each of which comprises 5 frequency bands). Accordingly, the set of the respective frequency bands included in the two ENDC combinations is set as the first-pass determined frequency band set, respectively. That is, the set of the respective frequency bands included in the ENDC group 1 is the frequency band set (1): { lte_band_a, lte_band_b, lte_band_c, nr_band_d, nr_band_e }, the set of individual bands contained in the ENDC combination 7 is a band set (2): { lte_band_a, lte_band_b, lte_band_e, nr_band_f, nr_band_g };
in the second round of iteration, the remaining operating band combinations, except for the subset of the band set that belongs to the previous round (i.e., the first round) of determination, are taken as the pending band combinations for the current round. Specifically, the ENDC combinations other than the ENDC combinations 2 to 6 and the ENDC combinations 8 to 10 (i.e., ENDC combinations 11 to 14) are regarded as the currently-round pending band combinations, wherein the pending band combination having the largest number of bands is ENDC combination 11 (including 4 bands, the number of bands being 2 or more). Thus, the set of frequency bands included in the ENDC combination 11 is defined as the second-round frequency band set (3): { lte_band_a, lte_band_b, nr_band_h, nr_band_i };
in a third iteration, the remaining operating band combinations, except for the subset of band sets belonging to the previous (i.e., first and second) round of determination, are used as pending band combinations for the current round. Specifically, the ENDC combinations other than ENDC combinations 2 to 6, ENDC combinations 8 to 10, and ENDC combinations 12 to 13 (i.e., ENDC combinations 14 and 15) are regarded as the band combinations to be processed of the current round, since only 2 bands are contained in each of ENDC combinations 14 and 15, the iterative process is stopped at this time, and the sets of the respective bands contained in ENDC combination 14 are regarded as the band set (4) determined by the third round, respectively: { lte_band_j, nr_band_k }, and a set of individual bands included in the ENDC combination 15 as a third round of determined band set (5): { LTE_band_J, NR_band_M }.
It should be noted that the english alphabets a to M are only indicators of frequency bands. Furthermore, the respective ENDC combinations in the above examples, the type and number of frequency bands each ENDC combination contains, and the number of total ENDC combinations supported by the terminal device, are merely non-limiting examples, and do not constitute a limitation on the operating frequency band combinations supported by the terminal device. In practical applications, the number of all operating band combinations supported by the terminal device may be much greater than the number listed above.
In the embodiment of the invention, the iteration scheme is adopted to determine the plurality of frequency band sets, so that compared with the method that a plurality of working frequency band combinations are randomly selected each time to be combined to obtain the frequency band set, on one hand, the method is favorable for avoiding the problem of missing the working frequency band combinations, and all the repeated frequency bands and corresponding parameters in different working frequency band combinations are combined into a single frequency band and parameters, so that the comprehensiveness of the obtained frequency band set is improved, and the occupied storage space is reduced to the greatest extent; on the other hand, compared with the unordered iteration mode, the method and the device for achieving the multi-frequency band iteration are capable of conducting iteration according to the sequence from large frequency bands to small frequency bands, improving iteration efficiency and achieving more efficient acquisition of the preconfigured multi-frequency band sets.
Referring to fig. 3, fig. 3 is a schematic diagram of a plurality of operating band combinations preconfigured in a switch register in the prior art. The total operating band combinations supported by the terminal device include ENDC combinations 1 to 15 listed in the above example.
As shown in fig. 3, in the prior art, not only the entire contents of ENDC combinations 1 to 15 are configured in a switch register, but also corresponding activation parameter combinations (not shown in the figure) for each ENDC combination are respectively configured in the switch register. As can be seen from the figure, there is a large amount of repetitive content in the content of the configuration, which results in a large amount of occupied storage space and an increase in configuration cost.
Referring to fig. 4, fig. 4 is a schematic diagram of a plurality of operating band sets preconfigured in a switch register according to an embodiment of the present invention. All the working frequency band combinations supported by the terminal equipment comprise ENDC combinations 1-15 listed in the example, and after a plurality of iterations, a plurality of frequency band sets are obtained: band set (1) to band set (5) (corresponding to ENDC combinations 1, 7, 11, 14, 15, respectively).
As shown in fig. 4, compared with the embodiment shown in fig. 3, in which the entire contents of ENDC combinations 1 to 14 are configured in the switch register, in the embodiment of the present invention, only the contents of the band set (1) to the band set (5) need to be configured in the switch register (that is, only the contents of 5 band combinations of ENDC combinations 1, 7, 11, 14 and 15 need to be configured, the number of band combinations needs to be configured is reduced by 8, the number of band is reduced by 31, and a large amount of repetitive contents is eliminated). Correspondingly, compared with the prior art, the method has the advantages that the corresponding activation parameter combinations of each ENDC combination are respectively configured in the switch register, in the embodiment of the invention, only the activation parameter sets (not shown in the figure) corresponding to the frequency band set (1) to the frequency band set (5) are respectively configured in the switch register, and the content of the activation parameters to be configured is greatly reduced.
Therefore, as can be seen from comparison of fig. 3 and fig. 4, by adopting the embodiment, the occupied storage space can be effectively reduced, and especially in a scene that the number of combinations of the working frequency bands supported by the terminal equipment is very large, the storage space occupation can be greatly reduced. Further, the configuration cost and the configuration complexity can be remarkably reduced.
