Technical Field

The present application relates to the field of communications technologies, and in particular, to a communications method, an electronic device, and a storage medium.

Background

The frequency bands supported by different operators in different regions of the world are mostly discontinuous and have smaller bandwidths, which are limited by the shortage of radio spectrum resources. The bandwidth of the frequency band is smaller, so that the requirement of high transmission rate cannot be met. For this reason, a carrier aggregation (carrier aggregation, CA) technique is introduced, and a plurality of frequency bands are aggregated together to obtain a CA combination, so that a larger bandwidth can be realized, and the transmission rate can be improved.

Since the combination of frequency bands CA supported by different terminal devices is different and the combination of frequency bands CA supported by different operators is also different, in some communication methods, public land mobile networks (public land mobile network, PLMNs) of each operator and the combination of CA supported by each operator are preconfigured in the terminal device. After the terminal equipment accesses the network provided by the operator, acquiring an operator PLMN corresponding to the network, and reporting to network equipment corresponding to the network based on the CA combination supported by the operator corresponding to the operator PLMN, so that the network equipment corresponding to the network can carry out carrier aggregation based on the reported CA combination.

However, when the frequency band supported by the operators changes, such as adding or subtracting the frequency band, the CA combination supported by each operator in the terminal device needs to be manually reconfigured, which is easy to miss or make mistakes.

It is understood that the network device 200 of the operator may be any implementable base station, such as macro base station, micro base station or decentralized unit-control unit (distribute unit control unit, DU-CU). Wherein the DU-CU is a device deployed in the radio access network and capable of wireless communication with the electronic device.

It is understood that the operator may be an operator in any region of the world, for example, the operator may include a plurality of operators such as chinese mobile (China Mobile Communication, CMCC), chinese telecommunications (China Union Communication, CUCC), chinese Telecommunications (CT), and indonesia telecommunications (Telkom Indonesia).

The terminal device 100 may include a baseband chip 110 and an application chip 120, the baseband chip 110 may include a CA combination reporting module 111, and the application chip 120 may include a CA combination generating module 121 and an operator PLMN & CA combination database 122.

In some alternative examples, baseband chip 110 may be a wireless internet module in a terminal device, such as a Modem C core in the terminal device. The application chip 120 may be an application (application processor, AP) processor in the terminal device.

In some alternative examples, the operator PLMN & CA combination database may store the CA combinations supported by the operator according to the PLMN of the operator, i.e. store the CA combinations supported by the operator and the operator in the operator PLMN & CA combination database after matching.

In the following, a description will be given of the communication method mentioned in some examples, and fig. 2 shows an interactive schematic diagram of a communication method, which can be applied to the communication system shown in fig. 1.

As shown in fig. 2, the communication method may include the steps of:

the CA combination reporting module 111 in the baseband chip 110 may send a query instruction to the network device 200 to query the current access network PLMN.

The network device 200 may return 202 the current access network PLMN to the CA combination reporting module 111 in the baseband chip 110.

203, The CA combination reporting module 111 in the baseband chip 110 may receive the current access network PLMN returned by the network device 200, and return the current access network PLMN to the CA combination generating module 121 of the application chip 120.

207 The CA combination reporting module 111 in the baseband chip 110 may generate a final reported CA combination based on the CA combination code stream sent by the CA combination generating module 121, and send the final reported CA combination to the network device 200, so that the network device 200 performs carrier aggregation processing based on the reported CA combination.

However, in the above communication method, when the frequency band supported by the operators changes, such as adding or subtracting the frequency band, the CA combination supported by each operator in the terminal device needs to be manually reconfigured, which is easy to miss or make mistakes.

In order to solve the above-mentioned problems, an embodiment of the present application provides another communication method, in which, after a terminal device accesses a network, a PLMN of an operator corresponding to the network is obtained, and a plurality of frequency bands supported by the operator are queried according to the PLMN of the operator, and the plurality of frequency bands supported by the operator are combined to obtain a plurality of CA combinations supported by the operator.

Thus, by combining a plurality of CA combinations, omission or errors caused by manual configuration can be reduced.

It will be appreciated that, since the CA combinations supported by different terminal devices are different, the CA combinations supported by different operators are also different, and therefore, the CA combinations supported by the terminal devices may occur, but the operators do not support, which may cause the terminal devices to fail to access the internet. Therefore, the plurality of CA combinations supported by the operator and the plurality of CA combinations supported by the terminal equipment can be matched to obtain the plurality of CA combinations supported by the terminal equipment and supported by the operator, namely the CA combinations finally reported by the terminal equipment, so that the network equipment corresponding to the operator can carry out carrier aggregation based on the CA combinations reported by the terminal equipment, and the success rate of surfing the network of the terminal equipment is ensured.

It can be understood that the terminal device may preset a plurality of frequency bands supported by each operator in all operators, and obtain a plurality of frequency bands supported by the operators while obtaining PLMNs of operators corresponding to the network, so as to update the plurality of frequency bands supported by the operators preset in the terminal device, that is, update the plurality of frequency bands supported by the operators preset in the terminal device in real time.

It can be understood that after the multiple CA combinations reported are matched, if the number of CA combinations is greater than the threshold value of the number of CA combinations supported by the terminal device and the network device, the multiple CA combinations matched can be cut to obtain multiple CA combinations that are finally reported. Therefore, the automatic cutting after the CA combination exceeds the limit can be realized, and the convenience of reporting the automatic cutting of the CA combination can be improved.

It will be appreciated that when the terminal device is powered on, it may attempt to access the current network and, after accessing the current network, obtain the operator PLMN and the supported third set of frequency bands of the current access network.

The ca combination reporting module 311 obtains the query instruction of the operator PLMN and the third frequency band set of the current access network issued by the network device 200.

It will be appreciated that a frequency band information list database is stored in the network device, where a plurality of frequency bands (i.e. a third set of frequency bands) supported by the operator PLMN and the operator are stored. When the frequency band supported by the operator changes, such as adding or subtracting the frequency band, the frequency band information list database in the network device can be directly refreshed, that is, the frequency band in the frequency band information list database is updated, such as adding or subtracting the frequency band.

The network device 200 returns 502 the operator PLMN and the third frequency band set of the current access network to the CA combination report module 311.

It can be understood that the network device may carry the operator PLMN and the first frequency band set of the current access network in the capability query signaling in the network access procedure, and return to the CA combination reporting module, that is, return the operator PLMN and the band list information.

The CA combination reporting module 311 returns the operator PLMN and the third frequency band set of the current access network to the CA combination generating module 321.

It may be appreciated that after the CA combination report module receives the operator PLMN and the third frequency band set of the current access network, the operator PLMN and the third frequency band set of the current access network may be sent to the CA combination generating module.

And 504, the CA combination generating module 321 inquires a frequency band set and R11 information supported by an operator from the operator PLMN & frequency band & R11 capability list database 322 according to the operator PLMN of the current access network.

It will be appreciated that the CA combination reported by the terminal device may change when the long term evolution (long term evolution, LTE) frequency band supported by the network device changes, and the MRDA combination reported by the terminal device may change when the New Radio (NR) frequency band supported by the network device changes. At this time, the CA combination version supported by the operator corresponding to the network device stored in the terminal device needs to be redeveloped, and continuously refreshed and maintained, and in the process of redeveloping the CA combination version supported by the operator corresponding to the network device stored in the terminal device, that is, in the process of redeveloping the CA combination supported by each operator in the terminal device, the number of CA combinations is too large, which is easy to miss or make mistakes. For this purpose, an operator PLMN & band & R11 capability list database, i.e. an operator PLMN of the operator, a plurality of bands supported by the operator and whether the operator supports R11 capability, may be stored in the terminal device.

It may be appreciated that, according to the operator PLMN of the current access network, the CA combination generating module may query, from the operator PLMN & band & R11 capability list database, a band set supported by the operator and R11 information, that is, a second band set supported by the operator and whether the operator supports R11, where R11 may refer to that the network device supports Release version.

In some optional examples, the CA combination generating module may update the frequency band set supported by the operator stored in the terminal device according to the third frequency band set.

505 The operator PLMN & band & R11 capability list database 322 returns the R11 information and the second set of bands supported by the operator corresponding to the operator PLLMN of the current access network.

It may be understood that the operator PLMN & frequency band & R11 capability list database stores an operator PLMN and a plurality of frequency bands supported by the operator, where the operator PLMN and the plurality of frequency bands supported by the operator may be obtained based on historical data of access of the terminal device to the network, for example, when the terminal device accesses the network a at a historical moment, the terminal device may obtain an operator PLMN and a supported frequency band set of the network device corresponding to the network a, and use the frequency band set supported by the network a as a second frequency band set, and store the second frequency band set in the operator PLMN & frequency band & R11 capability list database after matching with the operator PLMN of the network.

It will be appreciated that the terminal device CA combination specification capability module may store a plurality of CA combinations supported by the terminal device, also referred to as terminal device CA combination specification capabilities, with CA combination information.

In some optional examples, if the third frequency band set of the current access network returned by the network device is non-null, that is, the band list is non-null, the CA combination generating module may use the third frequency band set as the first frequency band set, and query CA combination information supported by the terminal device and also supported by the network device from the terminal device CA combination specification capability module based on the first frequency band set.

In some optional examples, if the third frequency band set of the current access network returned by the network device is null, that is, the band list is null, the CA combination generating module may use the second frequency band set as the first frequency band set, and query the CA combination information supported by the terminal device and also supported by the network device from the CA combination specification capability module of the terminal device based on the first frequency band set.

507 The terminal device CA combination specification capability module 323 returns CA combination information to the CA combination generation module 321.

It is understood that the terminal device CA combination specification capability module stores therein a plurality of CA combinations supported by the terminal device, the plurality of CA combinations having CA combination information.

The CA combination generation module 321 sends an acquisition instruction to acquire the clipping policy to the clipping policy module 324.

It can be appreciated that the CA combination generating module may determine whether CA combination cutting is required based on the CA combination information and R11 information supported by the operator (i.e. whether the operator supports R11), and when CA combination cutting is required, may obtain the cutting policy from the cutting policy module. Wherein, R11 may refer to that the network device supports Release version.

In some optional examples, if the operator supports R11, the terminal device may report 384 CA combinations at maximum, and if the number of CA combinations corresponding to the CA combination information is greater than 384, the CA combination generating module may obtain the clipping policy from the clipping policy module.

In some optional examples, if the operator does not support R11, the terminal device may report 128 groups of CA combinations at maximum, and if the number of groups of CA combinations corresponding to the CA combination information is greater than 128, the CA combination generating module may obtain the clipping policy from the clipping policy module.

509 The clipping policy module 324 returns the clipping policy to the CA combination generation module 321.

It will be appreciated that the clipping policy module may store the following clipping policies:

(1) in-band continuous carrier component cutting→ (2) uplink carrier component cutting→ (3) downlink carrier component cutting→ (4) final cutting scheme.

It will be appreciated that the above-described cutting steps (1) - (3) do not distinguish between sequential order. For step (1), the carrier components that are continuous in-band can be cut, for example, when the frequency band is B40 or B7, the combination of continuous CA in-band corresponding to B40 and B7 can be cut. CA combinations of more than 2 carrier components in the uplink frequency band may be cut out for step (2). And (3) cutting CA combination of more than 2 carrier components in the downlink frequency band. And thus a strategy of one-time cut down to less than 128 or 384 CA combinations can be obtained.

The CA combination generating module 321 cuts the CA combination information based on the cutting strategy, generates a CA combination code stream which is finally reported, and sends the CA combination code stream to the CA combination reporting module 311.

It can be understood that the CA combination generating module may cut the CA combination information based on the cutting policy, if the operator supports R11, obtain CA combination information of 384 or less groups of CA combinations, generate a CA combination code stream that is finally reported based on the CA combination information, and send the CA combination code stream to the CA combination reporting module. And if the operator does not support R11, obtaining CA combination information of 128 groups of CA combinations or less, generating a final reported CA combination code stream based on the CA combination information, and sending the CA combination code stream to a CA combination reporting module.

The CA combination reporting module 311 generates a final reported CA combination based on the CA combination code stream sent by the CA combination generating module 321, and sends the final reported CA combination to the network device 200, so that the network device 200 performs carrier aggregation processing based on the reported CA combination.

In the following, a communication method according to an embodiment of the present application is further described, and fig. 6 shows a schematic flow chart of a communication method, and as shown in fig. 6, the communication method may include:

And 601, the terminal equipment is electrified to search the network, and the CA combined reporting module acquires the PLMN and the band list.

It can be understood that, after the terminal device is powered on, the current network may be tried to be accessed, and after the current network is accessed, the CA combination reporting module may obtain the PLMN of the operator currently accessing the network and a plurality of frequency bands supported by the operator after being updated in real time, where the plurality of frequency bands supported by the operator after being updated in real time are also referred to as band list information, that is, the third frequency band set.

And 602, the CA combination reporting module transmits the acquired PLMN and the band list to the CA combination generating module of the AP core.

It may be understood that the AP core may be an application chip in the terminal device, such as an application program (application processor, AP) processor in the terminal device, and the CA combination reporting module may report the acquired PLMN and band list to the CA combination generating module of the application chip.

And 603, the CA combination generating module inquires a corresponding frequency band set and R11 information from the PLMN & frequency band & R11 capability list database of the operator according to the PLMN.

It may be appreciated that the CA combination generating module may query, based on the operator PLMN of the current access network, from the operator PLMN & band & R11 capability list database, the set of bands and R11 information supported by the operator, that is, the second set of bands supported by the operator and whether the operator supports R11.

In some optional examples, the CA combination generating module may update the frequency band set supported by the operator stored in the terminal device according to the third frequency band set.

And 604, the CA combination generation module judges whether the band list is empty, and if not, the step 605 is switched to, otherwise, the step 606 is switched to.

And 605, the CA combination generation module queries the corresponding CA combination code stream by using the band list.

In some alternative examples, when the band list is not empty, the CA combination information supported by the terminal device and also supported by the network device may be queried from the terminal device CA combination specification capability module through the band list information.

And 606, the CA combination generation module queries the corresponding CA combination code stream by using the queried frequency band set.

In some alternative examples, when the band list is empty, the CA combination information supported by the terminal device and supported by the network device may be queried from the terminal device CA combination specification capability module through the operator-supported frequency band set queried from the operator PLMN & frequency band & R11 capability list database.

607, The ca combination generating module determines whether the network supports the R11 capability, and if not, goes to step 608, otherwise goes to step 609.

It can be understood that after acquiring the CA combination information supported by the terminal device and also supported by the network device, it can be determined whether the current network supports R11.

It will be appreciated that in the case where the current network supports R11, the process goes to step 508, i.e. it is determined whether the CA combination corresponding to the CA combination information is greater than 128 groups. If the current network does not support R11, the process goes to step 509, i.e. it is determined whether the CA combination corresponding to the CA combination information is greater than 384 groups.

The CA combination generation module determines whether the CA combination is greater than 128 groups, and if yes, goes to step 610, otherwise goes to step 612.

It will be appreciated that in the case where the CA combination is greater than 128 groups, the process goes to step 510, where the CA combination generation module may obtain a clipping policy for clipping the CA combination from the clipping policy module. If the CA combination corresponding to the CA combination information is less than or equal to 128 groups, the step goes to step 512, where the CA combination generating module may directly report the CA combination information to the CA combination reporting module and report the CA combination information to the network.

The CA combination generation module determines whether the CA combination is greater than 384, and if yes, goes to step 610, otherwise goes to step 612.

It will be appreciated that in the case where the CA combination is greater than 384, the process goes to step 610, where the CA combination generation module may obtain a clipping policy for clipping the CA combination from the clipping policy module. If the CA combination corresponding to the CA combination information is less than or equal to 384 groups, the step goes to step 612, where the CA combination generating module may directly report the CA combination information to the CA combination reporting module and report the CA combination information to the network.

The CA combination generation module obtains a clipping strategy 610.

It will be appreciated that the clipping policy module may store the following clipping policies:

(1) in-band continuous carrier component cutting→ (2) uplink carrier component cutting→ (3) downlink carrier component cutting→ (4) final cutting scheme.

It will be appreciated that the above-described cutting steps (1) - (3) do not distinguish between sequential order. For step (1), the carrier components that are continuous in-band can be cut, for example, when the frequency band is B40 or B7, the combination of continuous CA in-band corresponding to B40 and B7 can be cut. For step (2), i.e. when the value is 2, CA combinations with more than 2 carrier components in the uplink band can be cut off. And (3) cutting CA combinations of more than 2 carrier components in the downlink frequency band when the value is 3. And thus a strategy of one-time cut down to less than 128 or 384 CA combinations can be obtained.

And 611, the CA combination generating module generates a CA combination code stream which is finally reported.

And 612, the CA combination generating module sends the finally reported CA combination to a CA combination reporting module and reports the CA combination to the network.

And then, matching with CA combination configuration supported by the specification default of the terminal product to obtain CA combination required to be reported by the terminal equipment under the network of the current operator, and generating the final CA combination required to be reported according to the CA combination reported by the terminal, the Release version capability of the network and a cutting strategy.

In some optional examples, the whole scheme comprises three functional design processes, analysis of frequency bands supported by an operator and PLMN information database files, matching of the frequency bands supported by the operator and CA combinations supported by default of terminal product specifications, and determining the CA combination which is finally required to be reported under the current network based on the matched CA combinations, network R11 capability and a cutting strategy.
