In order to clearly explain technical solutions in the embodiments of the present disclosure, before specifically developing and explaining the embodiments of the present disclosure, some terms applied in the embodiments are first described.
Double-card double-standby double-pass terminal: the terminal is provided with a plurality of transceiving channels and can support two cards to simultaneously transceive, namely, the two cards of the terminal can be simultaneously standby and can also be simultaneously in a service activation state.
Double-card bi-pass terminal: two cards of the dual-card dual-standby dual-pass terminal are in a service activation state at the same time.
Dynamic power sharing: the dual-card bi-pass terminal can dynamically adjust and distribute power between two network connections or two cards under the total maximum power preset.
NR (New Radio, new air): the 5G standard based on a brand-new air interface design of OFDM (Orthogonal Frequency Division Multiplexing) is also a very important cellular mobile technology basis for the next generation.
LTE (Long Term Evolution) is a UMTS (Universal Mobile Telecommunications System) technical standard established by The 3GPP (The 3rd Generation Partnership Project) organization.
USIM (Universal Subscriber Identity Module, universal Subscriber Identity card): is a component of a UMTS (Universal Mobile telecommunications System) network.
Hereinafter, technical solutions in example embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
In the related technical solution, although the dual card dual standby dual mode terminal has the capability of two cards to perform services simultaneously, but is limited by a Specific Absorption Rate (SAR) and a radio frequency capability of the terminal, when transmission powers allocated to a network a where a subscriber identity card (card a) is located and a network B where another subscriber identity card (card B) is located respectively exceed maximum powers that can be provided by the terminal, the terminal may autonomously adjust the transmission power of the subscriber identity card, for example, reduce the transmission power of one subscriber identity card, and even possibly disconnect the connection of one subscriber identity card. However, in this technical solution, since the power adjustment mechanism and result of the terminal are not coordinated with the network side, the network side does not know the reason of power drop or even connection failure, and the network side still tries to perform scheduling with the initially received maximum power capability in the subsequent power scheduling of the adjusted subscriber identity card, which not only wastes resources but also causes misjudgment on the channel state.
Therefore, the technical scheme of the embodiment of the present disclosure introduces an adjustment mechanism for dynamic power sharing between a dual-card dual-standby dual-pass terminal and a network in a dual-card dual-pass service scenario, and when the terminal determines to disconnect a network connection of one of the subscriber identity cards under an extreme condition, reporting that the reason for the network link failure before disconnection is dual-card power adjustment, thereby solving a risk caused by misjudgment of a channel environment by a network.
Fig. 1 is a schematic diagram illustrating an application scenario of the power adjustment method in an exemplary embodiment of the present disclosure.
Referring to fig. 1, the application scenario 100 may include a network device 110, and the network device 110 may be a device communicating with a terminal device 120 (or referred to as a communication terminal or a user terminal). Network device 110 may provide communication coverage for a particular geographic area and may communicate with terminal devices located within that coverage area. Alternatively, the network device 110 may be an evolved Node B (eNB) or eNodeB in an LTE system, or a network device in a 5G network, such as a base station.
The application scenario 100 further comprises at least one terminal device 120 located within the coverage area of the network device 110. The terminal device 120 is a dual-card dual-standby dual-channel user terminal. It should be noted that the terminal device 120 may be a portable computer, a smart phone, a vehicle-mounted terminal, and a tablet computer.
Further, in an example embodiment, when the first subscriber identity card and the second subscriber identity card are both in a traffic state and the sum of the allocated transmission powers of the first subscriber identity card and the second subscriber identity card is greater than the total transmission power of the terminal device 120, the terminal device 120 adjusts the transmission power of at least one subscriber identity card; reporting the power adjustment feedback information to the network device 110.
According to the technical scheme in the example embodiment, when the preset power adjustment condition is met, the transmitting power of the subscriber identity module card to be adjusted is adjusted, and power adjustment feedback information is reported to the network equipment, on one hand, better power adjustment state cooperation between the terminal side and the network side can be achieved, the situation that the terminal side autonomously adjusts power but is not synchronous with the network side is avoided, the network side monitors unknown power drop or link failure to seriously misjudge the channel state, unnecessary extra signaling overhead and improper scheduling configuration are brought, on the other hand, the network can reasonably adjust the maximum transmitting power of the terminal on the subscriber identity module card, and the power margin is more accurately estimated.
Fig. 2 shows a flow diagram of a power adjustment method according to some example embodiments of the present disclosure. The execution subject of the power adjustment method provided by the embodiment of the present disclosure may be a device with computing capability, such as the terminal device 120 in fig. 1. The power adjustment method includes steps S210 to S220, and the following describes in detail the power adjustment method in an example embodiment by taking an execution subject as a terminal device, and referring to the accompanying drawings, where the terminal device is a dual-card dual-standby dual-call terminal supporting dynamic power sharing, and the terminal device includes a first subscriber identity card and a second subscriber identity card.
Referring to fig. 2, in step S210, if the first subscriber identity card and the second subscriber identity card are both in a traffic state, and the sum of the allocated transmission powers of the first subscriber identity card and the second subscriber identity card is greater than the total transmission power of the terminal device, the transmission power of at least one subscriber identity card is adjusted.
In an example embodiment, both a first subscriber identity module and a second subscriber identity module of a dual-card dual-standby dual-active terminal are in a service activation state, and the dual-card dual-standby dual-active terminal determines that both the first subscriber identity module and the second subscriber identity module are in a connection state currently. The system combination of the first subscriber identity module card and the second subscriber identity module card of the dual-card dual-standby dual-active terminal can be various cellular mode combinations such as NR/NR, LTE/LTE, NR/LTE, EN-DC/LTE and the like.
It should be noted that the standard combination of the first subscriber identity card and the second subscriber identity card of the dual-card dual-standby dual-call terminal may also be other suitable standard combinations, such as NR/6G, LET/6G, and the like, which is also within the protection scope of the present disclosure. 6G is a wireless communication technology under development and discussion, namely, a sixth generation (6G) radio communication technology.
Further, in the example embodiment, when the sum of the transmission powers required by the first subscriber identity card and the second subscriber identity card is greater than the maximum transmission power of the terminal, it is determined that power adjustment needs to be performed on one subscriber identity card and/or the second subscriber identity card. If the two subscriber identity modules belong to the same operator, the power of which subscriber identity module can be adjusted by the terminal configured on the network side, or the power of which subscriber identity module can be adjusted by the terminal side in an autonomous decision-making manner; if the two subscriber identity cards belong to different operators, because the relationship of the networks in which the two subscriber identity cards are located is equal, how to adjust the configuration of the network side is difficult, and the terminal decides which subscriber identity card to adjust the power.
For example, if the access networks of the first user identification card and the second user identification card belong to the same operator, determining the user identification card to be adjusted based on network card decision information issued by the network device or terminal card decision information configured by the terminal device; and if the first subscriber identity module card and the access network of the subscriber identity module card belong to different operators, determining the subscriber identity module card to be adjusted based on the terminal card decision information configured by the terminal equipment. The network card decision information issued by the network device may be the user identification card information to be adjusted, which is determined by the network side according to the service priority information of the first user identification card and the second user identification card and/or the network compatibility information, for example, if the service of the first user identification card is a voice call service and the service of the second user identification card is a data transmission service, the issued card adjustment information may be the card identification information of the second user identification card.
The terminal card decision information configured by the terminal device includes information such as service priority information and/or network compatibility information. And the terminal equipment determines the user identification card to be adjusted based on the configured terminal card decision information. For example, if the service of the first subscriber identity card is a voice call service and the service of the second subscriber identity card is a data transmission service, the terminal device determines that the second subscriber identity card is a subscriber identity card to be adjusted.
And further, adjusting the transmitting power of the subscriber identity module card to be adjusted.
In an example embodiment, if the sum of the transmission power of the first subscriber identity card and the transmission power of the second subscriber identity card is greater than a first predetermined power threshold, the subscriber identity card to be adjusted is determined, and the transmission power of the subscriber identity card to be adjusted is adjusted based on a pre-configured power adjustment parameter. The power adjustment parameter may be a preconfigured power adjustment parameter issued by the network device, or may be a preconfigured power adjustment parameter of the terminal device, and the power adjustment parameter may include: and adjusting one or more of the number, the scaling and the chain breakage threshold value corresponding to the algorithm.
For example, when the dual-card bi-pass terminal supports dynamic power sharing, and when the transmit power on the subscriber identity card a plus the transmit power on the subscriber identity card B are greater than the maximum transmit power supported by the terminal, the terminal adjusts the transmit power on one of the subscriber identity cards, the adjusted transmit power value should satisfy the following formula (1), and the adjusted power can satisfy the minimum transmit power requirement of the current link,
PusimA+PusimB≤Ptotalmax (1)
the PusimA is the transmission power of the subscriber identity card a, the PusimB is the transmission power of the subscriber identity card B, and the Ptotalmax is the maximum transmission power supported by the terminal.
In step S220, power adjustment feedback is reported to the network device.
In an example embodiment, the power adjustment feedback is reported to the network device after the adjustment is complete. In some example embodiments, the power adjustment feedback includes a power adjustment reason, and optionally, the power adjustment feedback may also include information of a power adjustment difference.
In other exemplary embodiments, when the network side configures the power adjustment parameter in advance, the power adjustment feedback information reported by the terminal may include one or more of a power adjustment start instruction, a power adjustment stop instruction, and an adjustment result; when the terminal autonomously adjusts the power, the power adjustment feedback information reported by the terminal may include one or more of a difference between the ideal transmit power and the adjusted transmit power and an adjustment cause value, where the adjustment cause value may be a numerical value, for example, a double-card double-pass value is 1.
According to the technical scheme in the example embodiment of fig. 2, when the preset power adjustment condition is met, the transmitting power of the subscriber identity module card to be adjusted is adjusted, and power adjustment feedback is reported to the network device, on one hand, better power adjustment state cooperation between the terminal side and the network side can be realized, serious misjudgment on a channel state caused by that the terminal side autonomously adjusts power but is not synchronized with the network side and the network side monitors unknown power drop or link failure, unnecessary extra signaling overhead and improper scheduling configuration are brought, and on the other hand, the network can reasonably adjust the maximum transmitting power of the terminal on the subscriber identity module card, and more accurately estimate the power margin.
Further, in the exemplary embodiment, the terminal triggers and adjusts the uplink transmission power by using a preconfigured power adjustment parameter, such as a number and an adjustment ratio of an adjustment algorithm, issued by the network device, and reports power adjustment feedback information to the network side. The terminal device may also perform power adjustment autonomously, and report to network power adjustment feedback information through a signaling, where the power adjustment feedback information includes a power adjustment reason, and optionally, the power adjustment feedback information may also include information of a power adjustment difference. And when the power of one card cannot meet the formula (1) after the terminal is adjusted, the terminal stops transmitting the uplink data on one of the first subscriber identification card and the second subscriber identification card. Further, if the link maintenance requirement cannot be met and the link needs to be broken, the link of one card is broken, and the power adjustment reason needs to be reported to the broken network side before the link is broken.
Fig. 3 shows a schematic diagram of a power adjustment method according to further example embodiments of the present disclosure.
In step S305, the subscriber identity cards a and B of the dual-card dual-active terminal are in a service concurrency state.
In an exemplary embodiment, the dual-card dual-active terminal can simultaneously and concurrently process services through two subscriber identity cards. For example, when the network in which the first subscriber identity card a is located is a 5G NR network, and the network in which the second subscriber identity card B is located is an LTE network, both subscriber identity cards are in a connected state and have data transmission.
In step S310, it is determined whether the transmission power required by the subscriber identification cards a and B is greater than the total transmission power of the terminal.
In an example embodiment, when the transmit power on the first subscriber identity card a plus the transmit power on the second subscriber identity card B is not greater than the maximum transmit power supported by the terminal, the terminal sets the current transmit power according to the current path loss, network scheduled resources, and power adjustment requirements in accordance with the existing 3GPP standard.
When the data of the first subscriber identity card A and the second subscriber identity card B are overlapped on the time slot, the power of the first subscriber identity card A is P NR(p) Plus power, e.g. P, of a second subscriber identity card B LTE(q) May be greater than the total transmission power P of the terminal multi-SIM,total When the terminal supports dynamic power sharing, the terminal reduces the transmission power of one of the subscriber identity cards or disconnects the network connection of one of the subscriber identity cards, so as to solve the problem that the SAR (Specific Absorption Rate) is limited or exceeds the radio frequency capability of the terminal.
In step S315, the terminal determines which card to adjust the power value based on preset judgment logic, and performs power adjustment.
In an example embodiment, when two subscriber identity cards belong to the same operator, the decision of which subscriber identity card to reduce power may be based on network configuration or terminal decisions. For example, if the access networks of the first subscriber identity card and the second subscriber identity card belong to the same operator, the subscriber identity card to be adjusted is determined based on network card decision information issued by the network device or terminal card decision information configured by the terminal device. The network card decision information issued by the network device may be the user identification card information to be adjusted, which is determined by the network side according to the service priority information of the first user identification card and the second user identification card and/or the network compatibility information, for example, if the service of the first user identification card is a voice call service and the service of the second user identification card is a data transmission service, the issued card adjustment information may be the card identification information of the second user identification card.
In an example embodiment, when two subscriber identity modules belong to different operators, since the relationship between the two networks is equal, the subscriber identity module to be adjusted is determined based on the terminal card decision information at the terminal side, and the card decision may be based on a preconfigured service priority decision table, such as voice service priority data service; it is also possible to consider backward compatibility, such as preferentially adjusting the service of the NR card, keeping the service of the LTE card, and the terminal card decision information configured by the terminal device includes information such as service priority information and/or network compatibility information. And the terminal equipment determines the user identification card to be adjusted based on the configured terminal card decision information. For example, if the service of the first subscriber identity module is a voice call service and the service of the second subscriber identity module is a data transmission service, the terminal device determines that the second subscriber identity module is a subscriber identity module to be adjusted.
Further, there may be various embodiments for the terminal to adjust the power of a certain subscriber identity module card, and as long as the purpose of cooperatively processing the result with the network can be achieved, the embodiments are all considered feasible, for example, one scheme is a strong cooperation scheme for adjusting the algorithm, parameters and results synchronously with the network, and the other scheme is a weak cooperation scheme for the terminal to adjust itself and report the results to the network. It is assumed that the terminal decision will adjust the power of the first subscriber identity card.
In some embodiments, the power adjustment mechanism and algorithm recognized by both the network and the terminal may be defined in the specification, and optionally, the adjustment algorithm may be multiple. When establishing a connection, the network side, for example, when establishing an RRC (Radio Resource Control) connection, issues a power adjustment parameter required for power adjustment to the terminal, where the power adjustment parameter may include one or more of a number corresponding to an adopted adjustment algorithm, a scaling ratio, or a link-breaking threshold.
The terminal triggers the adjustment mechanism to perform power adjustment when the terminal meets the power adjustment condition, and optionally, the terminal may notify the network of the first subscriber identity card that the power adjustment scheme is activated in a DCI, a MAC (Media Access Control Address) CE (Control Element), a UAI (UE Assistance Information), or other manners.
Further, the terminal adjusts the power of one card according to a preset scaling algorithm. Because the network and the terminal have consensus on the algorithm for adjusting the power, the network can calculate the amplitude of the transmission power adjusted by the terminal through the time for adjusting activation and deactivation informed by the terminal and the received terminal transmission power. The power adjustment algorithm may include scaling/power-wise scaling/adding and subtracting a fixed value, etc., and a specific adjustment algorithm may be defined in various ways. The power adjustment may be performed for a certain physical channel, or for multiple physical channels, such as PUCCH/SRS/PUSCH, and the power adjustment schemes may be different due to different requirements for reliability and tolerance for error rate for each channel.
In other embodiments, the terminal and the network do not negotiate a predetermined power adjustment algorithm and parameter, after the terminal decides and adjusts the power of the first subscriber identity card, the terminal reports one or more of adjustment reasons, such as an adjustment reason value (a value shared by dual-card dual-pass dynamic power is, for example, 1) and an adjustment power difference (power before adjustment — power after adjustment) to the network corresponding to the first subscriber identity card through signaling, so that the network corresponding to the first subscriber identity card knows that the reason for the power reduction is not due to the change of the channel state, thereby avoiding misjudgment of the channel. The adjustment reason can be represented by a mapping table including the adjustment reason value and the corresponding adjustment reason, and therefore, only the number corresponding to the reason value is uploaded to the network. Optionally, at the same time, the terminal reports the same adjustment cause value and the adjustment power difference to the network corresponding to the second subscriber identity card, and the network corresponding to the second subscriber identity card may correspondingly evaluate and adjust the actual maximum transmission power of the second subscriber identity card at this time according to the information, so as to adjust the corresponding maximum power value in the subsequent power headroom, and more accurately evaluate the available channel power headroom. The reporting of the power headroom may be for PUCCH/PUSCH/SRS, etc. The signaling may be reported using a UE Assistance Information (UAI) or a PHR (Power Headroom Report) in a Media Access Control (MAC) CE (Control Element), or a newly defined MAC CE.
In step S320, it is determined whether the power is severely insufficient.
In an example embodiment, in an extreme case where power is severely insufficient, the terminal stops transmitting the uplink data on one of the first subscriber identification card and the second subscriber identification card. Further, if the minimum power for maintaining the link cannot be met, the terminal may decide to disconnect one of the subscriber identity cards, i.e., the target subscriber identity card.
In step S325, the terminal informs the network of the adjustment cause value through a signaling message before disconnecting the target subscriber identity card.
In an example embodiment, before disconnecting the connection of the to-be-adjusted subscriber identity card, the terminal needs to report the failure reason to the network corresponding to the broken-link subscriber identity card through a signaling message, where the failure reason is dual-card power adjustment or dual-card power sharing, optionally, the signaling may use UAI to report the adjustment reason, and the adjustment reason may be represented by a mapping table, where the mapping table includes an adjustment reason value and a corresponding adjustment reason, and therefore, only the number corresponding to the adjustment reason value may be uploaded to the network. The minimum power to maintain the link is generally determined by the PUCCH channel, since the channel reliability requirements are high and the underlying control signaling information is transmitted.
In step S330, the terminal adjusts the power of the subscriber identity card to be adjusted so that the sum of the transmission powers of the two subscriber identity cards is less than the total transmission power, and synchronizes the power reduction reason with the adjusted network through the signaling message.
According to the technical scheme in the example embodiment of fig. 3, on one hand, better power adjustment state coordination between the terminal side and the network side can be realized, the terminal side is prevented from autonomously adjusting power but is not synchronized with the network side, the network side monitors unknown power drop or link failure and seriously misjudges the channel state, unnecessary extra signaling overhead is brought, and improper scheduling is configured, and on the other hand, the network can reasonably adjust the maximum transmission power of the terminal on the subscriber identity module card, and more accurately estimate the power margin; on the other hand, when the two subscriber identity cards belong to different networks, the power adjustment parameters can be configured by the networks, and the power of which card is adjusted based on the terminal autonomous decision, so that the two subscriber identity cards are equal in network level, and the power terminal of which card is adjusted under different service scenes is most clear due to different strategies such as service priority, and therefore, the adjustment of which card is more reasonable based on the terminal card decision information of the terminal. The network may further control the mechanism of power adjustment by configuring the power adjustment parameters.

The USIM1 450 is the main card of the dual-card dual-pass mobile phone terminalThe method comprises the steps that an NR network is accessed, a secondary card namely USIM2 455 is accessed to an LTE network, a dual-card dual-pass mobile phone terminal is provided with at least two radio frequency RF transmission channels namely a radio frequency transmission chain 1 425 and a radio frequency transmission chain 2 430, and when the secondary card LTE is in an idle state and a primary card USIM1 NR is in a service state, the two RF transmission channels are both occupied by the NR network to form NR 2T emission. When the auxiliary card USIM 2LTE has a service to enter a connected state, one of the RF channels, i.e., the radio frequency transmission chain 2 430, is switched to the LTE radio frequency front end to form an architecture of NR 1T + LTE 1T, and at this time, the transmission power on the NR radio frequency front end 405 is named as P NR The transmission power of the LTE RF front end 415 is named P LTE 。
If P NR And P LTE And if the sum is greater than the total transmitting power of the terminal, determining the user identification card to be adjusted, and adjusting the transmitting power of the user identification card to be adjusted based on the pre-configured power adjustment parameter. The power adjustment parameter may be a preconfigured power adjustment parameter issued by the network device, or may be a preconfigured power adjustment parameter of the terminal device, and the power adjustment parameter may include: and adjusting one or more of the number, the scaling and the chain breakage threshold value corresponding to the algorithm.
Further, in the exemplary embodiment, the terminal triggers and adjusts the uplink transmission power by using a preconfigured power adjustment parameter, such as a number and an adjustment ratio of an adjustment algorithm, issued by the network device, and reports power adjustment feedback information to the network side. The terminal device may also perform power adjustment autonomously, and report power adjustment feedback information to the network through signaling, where the power adjustment feedback information includes a power adjustment reason, and optionally, the power adjustment feedback information may also include information of a power adjustment difference. When the power of a certain card cannot meet the formula (1) after the terminal is adjusted, the terminal stops transmitting the uplink data on one of the first subscriber identity card and the second subscriber identity card. Further, if the link can not be maintained and needs to be broken, the terminal disconnects the link of one card, and needs to report the reason to the network side before the link is broken
