Description

Communication method, communication device and electronic equipment

Technical Field

The application belongs to the technical field of wireless communication, and particularly relates to a communication method, a communication device and electronic equipment.

Background

With the development of wireless communication technology, the frequency bands and standards that wireless communication devices need to support are increasing. For example, due to the diversity of frequency bands used by different operators and the dual connectivity (e.g., ENDC: EUTRA-NR Dual Connection, i.e., dual connectivity with evolved universal communication Radio access network (Evolved Universal Terrestrial Radio Access, EUTRA) as a primary cell group (MCG), and New air interface (NR) as a Secondary Cell Group (SCG) combination, a 5G terminal needs to support a wide variety of frequency bands and formats. In the process of implementing the present application, the inventor finds that at least the following problems exist in the prior art: although the wireless communication device can support a plurality of frequency bands and modes on the hardware, the hardware is not fully utilized, and part of the hardware is in an idle state in many times. For example, in the early stage of 5G network construction, in the case where ENDC coverage is insufficient, most of the time, only the 4G path is in an active state and the 5G path is in an idle state in the wireless communication device supporting ENDC. For another example, as 5G technology evolves, when independent networking (SA) is increasing, most of the wireless communication devices supporting ENDC only have 5G channels in an operating state and 4G channels in an idle state, so that the 4G channels cannot be effectively utilized.

Referring to fig. 1, the present application provides a communication method applied to an electronic device, where the electronic device includes a first transceiver path, a second transceiver path, and a first interface and a second interface; the first receiving and transmitting path supports a first frequency band, the second receiving and transmitting path supports a second frequency band, the first interface is used for being connected with a first user identity identification card, the second interface is used for being connected with a second user identity identification card, the first user identity identification card corresponds to a first network operator, and the second user identity identification card corresponds to a second network operator; the method comprises the following steps:

Step 101: searching a first type of first network of the first network operator, wherein the frequency band of the first network is the first frequency band, and the first type of first network is an independent networking first network;

step 102: connecting the first network of the first network operator through the first transceiving path under the condition that the first network of the first network operator is successfully searched;

The first subscriber identity card may be a primary card and the second subscriber identity card may be a secondary card.

The first frequency band includes one or more frequency bands and the second frequency band includes one or more frequency bands. Referring to fig. 2, the electronic device includes a first transceiver path 201 and a second transceiver path 202. In particular, the electronic device may be an electronic device supporting dual connectivity (e.g., ENDC). The dual-connection frequency band combination supported by the electronic device may be at least one of b39+n41, b3+n41, b3+n28, b3+n1, b1+n8, and the like. The first transceiving path 201 may be connected to a 5G base station or may be connected to a 4G base station; the second transceiving path 202 may be connected to any one of a 5G base station, a 4G base station, a 3G base station, and a 2G base station. Referring to fig. 3, in the case where there is a first network of a first network operator that is independently networked and there is a second network of a second network operator that is the second frequency band, the first transceiving path 201 is wirelessly connected to a base station of the first network, and the second transceiving path 202 is wirelessly connected to a base station of the second network. Specifically, the first network may be a 5G SA network, and the second network may be a 4G network, that is, a base station of the 5G SA network is wirelessly connected to the first transceiving path 201, and a base station of the 4G network is wirelessly connected to the second transceiving path 202, so that simultaneous independent connection of the 5G network and the 4G network is realized.

The first network operator and the second network operator may be the same network operator or may be different network operators.

Most of the electronic devices currently on the market for wireless communication only support dual card dual standby (Dual Sim Dual Standby, DSDS) and not dual card dual pass (Dual SIM Dual Active, DSDA) even though two subscriber identity cards can be installed. Referring to fig. 4, the following description describes, as an example, a dual connectivity electronic device supporting the combination of the frequency bands b3+n41, a network residence flow of the electronic device supporting only dual cards and dual standby, and a data residence flow of the electronic device supporting only dual cards and dual standby:

401. In the case where the card 1 is a main card, the card 1 corresponds to the carrier 1, the card 2 is a sub-card, the card 2 corresponds to the carrier 2, and the card 1 prioritizes the 5G network, the card 1 network searching is performed.

402. It is determined whether the operator 1 has an N41 SA network.

403. If the carrier 1 has an N41 SA network, the card 1 is connected to the N41 network, goes through the TRX2 path, and the card 2 stands by (standby).

404. If the operator 1 does not have the N41 SA network, judging whether the operator 1 has the B3+N41 network or not;

405. if the carrier 1 has a b3+n41 network, the card 1 is connected to the b3+n41 network and the card 2 stands by.

406. If the operator 1 does not have the b3+n41 network, it is determined whether the operator 1 has a long term evolution (Long Term Evolution, LTE) network.

407. If the operator 1 has an LTE network, the card 1 is connected to LTE, and goes through the TRX1 path, and the card 2 stands by.

408. If the operator 1 does not have the LTE network, judging whether the operator 1 has a 2G/3G B3 network.

409. If the operator 1 has a 2G/3G network, the card 1 is connected with the 2G/3G network, and goes through the TRX1 path, and the card 2 stands by.

410. If the carrier 1 does not have a 2G/3G network, the card 1 has no network, no data connection, and the card 2 stands by.

Only the electronic equipment supporting double cards and double standby can only have one card to carry out data service at the same time, and when the call service is carried out, the data service is interrupted, and the advantages of the double cards can not be fully exerted. For example, in a scenario with strong timeliness such as a game or navigation, a user needs to use a data network, and if a phone is accessed, a voice call occupies a transmission path, the quantity and flow cannot be used, the navigation cannot be updated in time, the game is interrupted, and the user experience is seriously affected. In the application, different user identification cards can be respectively connected with different networks at the same time, so that double-card double-pass can be realized, not only can two different networks be simultaneously used for carrying out data service, but also different networks can be simultaneously used for carrying out communication service and data service respectively.

Referring to fig. 7, the following describes the above communication method by taking a dual-connectivity electronic device supporting two frequency bands, namely b3+n41 as an example:

in the case that the first subscriber identity card (abbreviated as card 1) is a main card, the second subscriber identity card (abbreviated as card 2) is a sub card, and the data network is opened, and the card 1 searches for the network if the card 1 prioritizes the 5G network, it is determined whether the first network operator (abbreviated as operator 1) has the 5G SA network of N41. If the carrier 1 has an N41 SA network, then the card 1 connects to the N41 SA network, walks through the TRX2 path, and performs a card 2 network search. It is determined whether operator 2 has a B3 LTE network. If the card 2 has a B3 LTE network, the card 1 is connected with an N41 SA network and walks through a TRX2 path; the card 2 is connected with the B3 LTE network and walks through the TRX1 path. If the card 2 does not have the B3 LTE network, the method sequentially judges whether the operator 2 has the B3 3G/2G network. If the operator 2 has a B3 3G/2G network, the card 1 is connected with an N41 SA network and walks through a TRX2 path; card 2 connects to the B3 3G/2G network, walks the TRX1 path. If the operator 2 does not have the B3 3G/2G network, the card 1 is connected with the N41 SA network and walks through the TRX2 path; card 2 stands by.

If the operator 1 does not have the N41 SA network, judging whether the operator 1 has the B3+N41 NSA network, if the operator 1 has the B3+N41 NSA network, the card 1 is connected with the B3+N41 NSA network, and goes through the TRX1 and TRX2 paths, and the card 2 stands by.

If the operator 1 does not have the N41 SA network, judging whether the operator 1 has the B3 and B41 LTE networks, if the operator 1 has the B3 and B41 LTE networks, the card 1 is connected with the B3 LTE network, walks through the TRX1 path, and executes the card 2 network searching. It is determined whether the operator 2 has an N41 SA network. If the operator 2 has an N41 SA network, the card 1 is connected with a B3 LTE network and walks through a TRX1 path, and the card 2 is connected with an N41 SA network and walks through a TRX2 path. If operator 2 does not have an N41 SA network, it is determined whether operator 2 has a B41 LTE network. If the operator 2 has a B41 LTE network, the card 1 is connected with the B3 LTE network and walks through the TRX1 path, and the card 2 is connected with the B41 LTE network and walks through the TRX2 path. If operator 2 does not have a B41 LTE network, it is determined whether operator 2 has a B3 LTE network. If the operator 2 has a B3 LTE network, the card 1 cuts a B41 LTE network, walks a TRX2 path, and the card 2 is connected with the B3 LTE network, walks a TRX1 path. If the operator 2 does not have the B3 LTE network, the method sequentially judges whether the operator 2 has the B3 3G/2G network. If the operator 2 has a B3 3G/2G network, the card 1 cuts the B41 LTE network, walks the TRX2 path, and the card 2 is connected with the B3 3G/2G network, walks the TRX1 path. If the operator 2 does not have the B3 3G/2G network, the card 1 is connected with the B3 LTE network, the TRX1 path is taken, and the card 2 has no network.

If operator 1 has neither B3 nor B41 LTE network, it is in turn determined if operator 1 has a B33G/2G network. If the operator has a B33G/2G network, the card 1 is connected with the B33G/2G network, walks through the TRX1 path, and performs card 2 network searching. It is determined whether the operator 2 has an N41SA network. If the operator 2 has an N41SA network, the card 1 is connected with a B33G/2G network, the TRX1 path is taken away, and the card 2 is connected with an N41 network, the TRX2 path is taken away. If operator 2 does not have an N41SA network, then a determination is continued as to whether operator 2 has a B41 LTE network. If the operator 2 has a B41 LTE network, the card 1 is connected with the B33G/2G network, the TRX1 path is taken away, and the card 2 is connected with the B41 LTE network, the TRX2 path is taken away. If the operator 2 does not have the B41 LTE network, the card 1 is connected with the B33G/2G network, the TRX1 path is taken, and the card 2 has no network.

If the operator 1 does not have the B33G/2G network, judging whether the operator 2 has an N41SA network, a B3+B41 NSA network, a B3 or B41 LTE network and a B33G/2G network in sequence, if the operator 2 has the N41SA network, the card 1 has no network, and the card 2 has the N41SA network and goes on the TRX2 path. If carrier 2 does not have an N41SA network with a b3+b41 NSA network, card 1 does not have a network and card 2 is connected to the b3+b41 NSA network, taking TRX1 and TRX2 paths. If the operator 2 does not have a B3+B41 NSA network and has a B3 or B41 LTE network, then the card 1 does not have a network, and the card 2 is connected with the B3 or B41 LTE network and walks through the TRX1 or TRX2 path. If the operator 2 does not have B3 or the B41 LTE network has B33G/2G network, the card 1 does not have a network, and the card 2 is connected with the B33G/2G network and walks through the TRX1 path. If carrier 2 does not have a B33G/2G network either, neither card 1 nor card 2 has a network.

Optionally, the method further comprises:

under the condition that the electronic equipment is connected with the network of the first network operator and the network of the second network operator, if a call access request of a first target user identity card is received, determining whether the second receiving and transmitting channel is connected with a network corresponding to a second target user identity card;

under the condition that the second receiving and transmitting passage is determined to be connected with the network corresponding to the second target user identity card, sequentially searching the first network corresponding to the second target user identity card and the second network corresponding to the second target user identity card, wherein the second network is a second network of the first frequency band;

the first target user identification card is one of the first user identification card and the second user identification card, and the second target user identification card is the other of the first user identification card and the second user identification card.

And carrying out the call service of the first target user identification card through a second receiving and transmitting path.

Referring to fig. 2, the electronic device includes a first transceiver path 201 and a second transceiver path 202. In particular, the electronic device may be an electronic device supporting dual connectivity (e.g., ENDC). The first transceiving path 201 (i.e. TRX 2) may be connected to a 5G base station or a 4G base station; the second transceiving path 202 (i.e., TRX 1) may be connected to any one of a 5G base station, a 4G base station, a 3G base station, and a 2G base station. The voice call service is typically a 2G or 3G call, and needs to be performed through the second transceiver path 202.

Referring to fig. 3, in the case where there is a first network of a first network operator that is independently networked and there is a second network of a second network operator that is the second frequency band, the first transceiving path 201 is wirelessly connected to a base station of the first network, and the second transceiving path 202 is wirelessly connected to a base station of the second network. Specifically, the first network may be a 5G SA network, and the second network may be a 4G network, that is, a base station of the 5G SA network is wirelessly connected to the first transceiving path 201, and a base station of the 4G network is wirelessly connected to the second transceiving path 202. In addition, when the first transceiver path 201 is wirelessly connected to a base station of the 5G SA network of the first network operator, the second transceiver path 202 may be connected to a 3G or 2G network of the second network operator. Alternatively, the first transceiver path 201 may be wirelessly connected to a base station of a 5G SA network of a second network operator, and the second transceiver path 202 may be wirelessly connected to a base station of a 4G network of the first network operator. Of course, when the first transceiver path 201 is wirelessly connected to a base station of the 5G SA network of the second network operator, the second transceiver path 202 may also be wirelessly connected to a base station of the 3G network or the 2G network of the first network operator.

Referring to fig. 6, the first transceiver path 201 may be wirelessly connected to a base station of a 4G network of a second network operator, and the second transceiver path 202 may be wirelessly connected to a base station of a 4G network, a 3G network, or a 2G network of the first network operator. In addition, the first transceiver path 201 may be wirelessly connected to a base station of a 4G network of a first network operator, and the second transceiver path 202 may be connected to a 5G SA network, a 4G network, a 3G network, or a 2G network of a second network operator.

After accessing the call service, referring to fig. 8, the first transceiver path 201 is connected to the 4G or 5G network for data service, and the second transceiver path 202 is connected to the 2G or 3G network for call service.

In the prior art, when an external call request is accessed, the double-card double-standby terminal can cause data interruption no matter which card is used for call. In the embodiment of the application, the data service and the call service can be respectively carried out by utilizing the two receiving and transmitting paths of the electronic equipment, so that the data can not be cut off when the call service is carried out. Moreover, no matter which subscriber identity card is accessed to the call service, the other subscriber identity card can perform the data service. The voice and data double-card double-pass effect is realized, and the user experience is improved.

Of course, if the second transceiving path is not connected to the network corresponding to the second target user identification card, but is connected to the network corresponding to the first target user identification card, the ongoing data service of the first target user identification card is directly switched to the call service.

In the embodiment of the application, when the first network of the first frequency band corresponding to the second target user identification card and the second network of the first frequency band corresponding to the second target user identification card (namely, the second network of the second type) are searched in sequence, the second network of the first frequency band corresponding to the second target user identification card is searched only under the condition that the first network of the first frequency band corresponding to the second user identification card is not searched.

Specifically, under the condition that the second transceiving path is determined to be connected with the network corresponding to the second target user identification card, searching the first network corresponding to the second target user identification card and the second network corresponding to the second target user identification card in sequence, and connecting a fifth target network through the first transceiving path comprises the following specific processes:

Under the condition that the second receiving and transmitting path is determined to be connected with the network corresponding to the second target user identification card, searching the first network corresponding to the second target user identification card;

under the condition that the first network corresponding to the second target user identity card is successfully searched, the first network corresponding to the second target user identity card is connected through the first receiving and transmitting passage;

if the first network corresponding to the second target user identification card is not searched, continuing searching the second network corresponding to the second target user identification card;

and under the condition that the second network corresponding to the second target user identity card is successfully searched, connecting the two second networks corresponding to the second target user identity card through the first receiving and transmitting path.

The first network of the first frequency band corresponding to the second target user identification card may be an independently networked 5G SA network.

The following illustrates the dual card state and internal circuit switching flow when there is an external call request access after dual card network residence.

For example 1, referring to fig. 9, the initial network-resident status of the electronic device is a network connection with both the first network operator and the second network operator. When the card 1 requests call access, it is determined whether the card 2 occupies the TRX1 path (i.e., it is determined whether the card 1 occupies the TRX1 path), and if the card 2 occupies the TRX1 path (i.e., the card 1 does not occupy the TRX1 path), the card 1 cuts the TRX1 and the card 2 data cuts the TRX2 path. Then judging whether the operator 2 has a 5G SA network of the first frequency band, if the operator 2 has the 5G SA network of the first frequency band, the card 1 maintains the call to go away TRX1, and the card 2 cuts the 5G SA network of the first frequency band to go away TRX2, so as to realize DSDA. If the operator 2 does not have the 5G SA network of the first frequency band, judging whether the operator 2 has the 4G network of the first frequency band, if the operator 2 has the 4G network of the first frequency band, the card 1 maintains the call routing TRX1, and the card 2 cuts the 4G network routing TRX2 of the first frequency band to realize DSDA. If the carrier 2 does not have the 4G network of the first frequency band, the card 1 maintains the call to the TRX1, and the card 2 temporarily has no data network. And after the call is ended, recovering the initial network-resident state. When the operator 2 has the 5G SA network of the first frequency band or the 4G network of the first frequency band, the double-pass of voice and data cards can be realized, namely, the data can not be cut off in the call process.

For example 2, referring to fig. 10, the initial network-resident status of the electronic device is a network connection with both the first network operator and the second network operator. When the card 2 requests call access, it is determined whether the card 1 occupies the TRX1 path (i.e., it is determined whether the card 2 occupies the TRX1 path), and if the card 1 occupies the TRX1 path (i.e., the card 2 does not occupy the TRX1 path), the card 2 cuts the TRX1 and the card 1 data cuts the TRX2 path. Then judging whether the operator 1 has a 5G SA network of the first frequency band, if the operator 1 has the 5G SA network of the first frequency band, the card 2 maintains the call to go to TRX1, and the card 1 cuts the 5G SA network of the first frequency band to go to TRX2 to realize DSDA. If the operator 1 does not have the 5G SA network of the first frequency band, judging whether the operator 1 has the 4G network of the first frequency band, if the operator 1 has the 4G network of the first frequency band, the card 2 maintains the call to go away the TRX1, and the card 1 cuts the 4G network of the first frequency band to go away the TRX2 to realize DSDA. If the carrier 1 does not have the 4G network of the first frequency band, the card 2 maintains the call to the TRX1, and the card 1 temporarily has no data network. And after the call is ended, recovering the initial network-resident state. When the operator 1 has the 5G SA network of the first frequency band or the 4G network of the first frequency band, the double-pass of voice and data cards can be realized, namely, the data can not be cut off in the call process.

In a specific implementation process, part of the steps can be omitted according to needs, for example, according to the network distribution condition of an actual network operator, when a network of a certain standard which does not necessarily have a certain frequency band of a certain network operator is determined, the step of searching for the network of the frequency band can be omitted.

step 1101: under the condition that the electronic equipment is connected with the network of the first network operator and the network of the second network operator, if a call access request of the first target user identity card is received, determining whether the second receiving and transmitting channel is connected with the network corresponding to the second target user identity card;

Step 1102: under the condition that the second receiving and transmitting passage is determined to be connected with a network corresponding to the second target user identity card, sequentially searching a first network corresponding to the second target user identity card and a second network corresponding to the second target user identity card, wherein the second network is a second network of the first frequency band, and the frequency band of the first network is the first frequency band;

step 1103: a fifth target network is connected through the first receiving and transmitting path, wherein the fifth target network is the first network which is successfully searched out first in the first network corresponding to the second target user identification card and the second network corresponding to the second target user identification card;

and under the condition that the second network corresponding to the second target user identity card is successfully searched, connecting the second network corresponding to the second target user identity card through the first receiving and transmitting path.

In a specific implementation process, part of the steps may be omitted as required, for example, if the network operator corresponding to the second target user identification does not lay out the first network of the first frequency band, the first network of the first frequency band corresponding to the second target user identification card does not need to be searched, and likewise, if the network operator corresponding to the second target user identification does not lay out the second network of the first frequency band, the second network of the first frequency band corresponding to the second target user identification card does not need to be searched.
