Detailed Description

The technical solution of the present application will be further clearly and completely described below with reference to the accompanying drawings.

The electronic equipment can access the internet through a user card installed in the electronic equipment to realize internet surfing services. The electronic device may be a mobile terminal device such as a mobile phone, a personal computer, a tablet computer, a notebook computer, a handheld computer, and a netbook, or may be a device such as a television, an ultra-mobile personal computer (UMPC), a Personal Digital Assistant (PDA), a wearable device, a virtual reality device, and a Customer Premises Equipment (CPE). The user card may be a SIM card, or may also be another type of user card such as a Universal Subscriber Identity Module (USIM), an Embedded SIM card (eSIM), and the like.

In the following, a plurality of implementation manners and specific embodiments of the present application are described by taking an electronic device as a mobile phone and a user card as an SIM card as an example.

Referring to fig. 1, fig. 1 shows a dual SIM mobile phone with a first SIM card and a second SIM card. At present, the number of the mobile phones with the double SIM cards in the market already accounts for more than 80% of the total number of the mobile phones, and the number of users using the mobile phones with the double SIM cards is also close to 40% of the number of users using the mobile phones. Dual SIM card handsets usually support a Dual SIM Dual Active (DSDA) mode or a Dual SIM Dual Standby (DSDS) mode, wherein most of the Dual SIM card handsets support the DSDS mode, and the support rate of the DSDA mode is less than 10%.

Compared with a DSDA mode mobile phone, the DSDS mode mobile phone can only use one of the SIM cards to perform an internet access service (the internet access service may also be referred to as an internet access data service or a data service) at the same time, and cannot implement a concurrent function of a dual-card internet access service, so that the mobile phone cannot provide higher service quality.

Although the mobile phone in the DSDS mode cannot perform concurrence of dual-card internet access services, the implementation of rigid protocol flows related to network searching registration, location area update, and the like of the dual cards, and signaling messages of the dual cards may still be transmitted and received on the dual cards. For example, the mobile phone performs double-card switching through a single radio frequency channel similar to a single-pole double-throw mechanism to realize the signaling sending and receiving of the double cards, and the time division concurrency effect can be achieved.

In recent years, for a mobile phone in a DSDS mode, some chipmakers have realized "dual-card concurrency" of different kinds of services through a time division mechanism of a single radio frequency channel. For example, a first SIM card in a mobile phone is used as a default data account to perform internet access service, and a second SIM card is used for volte (voice over lte) call service. In this way, the internet access rate and the internet access delay of the first SIM card are greatly discounted, that is, the internet access rate of the first SIM card is reduced, and the internet access delay is increased. In addition, the dual-card service scheme is still a scheme for switching a default data account under a single radio frequency channel model, and at the same time, the same Application program (APP) in the mobile phone can only perform service on the first SIM card or the second SIM card, and the mobile phone does not realize real concurrent dual-card internet access service. The mobile phone cannot fully utilize the service carrying capacity of the dual cards and cannot provide higher service quality.

In addition, when the mobile phone performs internet access switching between the first SIM card and the second SIM card, default data account switching needs to be performed. The default data account can be switched by the manual operation of the mobile phone of the user or the automatic operation of the mobile phone. The switching of the default data account needs several seconds to tens of seconds, the internet access service of the application program is interrupted in the period of time, and the waiting time for recovering the internet access service on the newly determined default data account is long, which affects the use experience of the user.

Further, the default data account is automatically switched (i.e., not manually switched by the user) for the cell phone. Before switching the default data account, the mobile phone determines the service quality of the first SIM card through the signal strength of the first SIM card as the default data account, Round-trip time (RTT) of the service data, and rate information (i.e. rate information of the service data transmitted in the kernel layer). The quality of service for the second SIM card can only be roughly determined by the network access technology (the network access technology may be, for example, based on the third Generation mobile communication technology (3rd-Generation, 3G), based on the fourth Generation mobile communication technology (4rd-Generation, 4G), etc.) and the signal strength of the second SIM card. In this case, because the internet access service is performed only on the first SIM card, and the second SIM card has no service data (the service data may also be referred to as service data or a service data packet) sampling information, the mobile phone cannot accurately know the bandwidth capability of the second SIM card. The mobile phone cannot accurately know the bandwidth capability of the second SIM card, and thus cannot ensure the quality of the service of using the second SIM card to perform the internet access service. If the mobile phone determines that the service quality of the currently used first SIM card for performing the internet access service is poor, and the second SIM card is switched to the default data account, the situation that the service quality provided by the second SIM card is worse due to the smaller bandwidth exists, so that the mobile phone cannot provide better service quality, the user experience is affected, and the user experience may also be worse.

In summary, the current DSDS mode mobile phone has a problem that the service carrying capability of the dual cards cannot be fully utilized, and a problem that better service quality cannot be provided and user experience is affected.

The application provides a service processing method applied to a mobile phone in a DSDS mode, wherein the mobile phone comprises a first SIM card and a second SIM card. After the mobile phone is powered on, the mobile phone activates Data connection of each SIM card, for example, the mobile phone activates Packet Data Protocol (PDP) connection of each SIM card in 2G and 3G networks, or the mobile phone activates Public Data Network (PDN) connection of each SIM card in 4G networks, or the mobile phone activates Protocol Data Unit (PDU) session connection of each SIM card in 5G networks, and so on. And the mobile phone creates a data channel for each SIM card to transmit the service data (service data may also be referred to as service packet) of the internet service between the SIM card and the internet, for example, a first data channel is created for the first SIM card, and a second data channel is created for the second SIM card, so as to form a dual data channel. The first data channel and the second data channel may be Internet Protocol (IP) data channels, respectively. The service data can be an IP data packet transmitted between an application in the mobile phone and an application server for supporting the application in the Internet.

In addition, the mobile phone may use the first SIM card as a default data account for performing internet access services, and use the second SIM card as a non-default data account. For a user layer of the mobile phone, the default data account is still only one first SIM card, and Modem radio frequency resources in the mobile phone are also mainly supplied to the first SIM card, that is, after the mobile phone is started, the mobile phone defaults to transmit service data of the internet access service through a first data channel corresponding to the first SIM card.

In the process that the mobile phone carries out internet surfing service through the first SIM card, the mobile phone can determine whether the service quality of the first SIM card meets the current internet surfing requirement. If the service quality of the first SIM card cannot meet the current internet access requirement, the mobile phone may select a suitable SIM card from the first SIM card and the second SIM card to perform the internet access service according to the acquired first bandwidth of the first SIM card and the acquired second bandwidth of the second SIM card.

For example, if the mobile phone determines that the first bandwidth of the first SIM card is much greater than the second bandwidth of the second SIM card according to the first bandwidth of the first SIM card and the second bandwidth of the second SIM card, the mobile phone determines to continue to use the first SIM card for the internet access service, that is, to use the first data channel corresponding to the first SIM card for the transmission of the service data. If the mobile phone determines that the second bandwidth of the second SIM card is much larger than the first bandwidth of the first SIM card, the mobile phone determines to use the second SIM card for the internet access service, i.e. to use the second data channel corresponding to the second SIM card for the transmission of the service data. Otherwise, if the synthesized bandwidth of the first SIM card and the second bandwidth of the second SIM card is much larger than the first bandwidth of the first SIM card, the mobile phone determines to use the first SIM card and the second SIM card to perform the internet access service at the same time, that is, to use the first data channel and the second data channel to perform the service data transmission at the same time.

According to the service processing method applied to the mobile phone in the DSDS mode, after the mobile phone is started, the first data channel is established for the first SIM card, the second data channel is established for the second SIM card, and the requirement for double-card switching can be well met. And the mobile phone can select the SIM card for carrying out the internet surfing service from the first SIM card and the second SIM card according to the first bandwidth of the first SIM card and the second bandwidth of the second SIM card, so that the mobile phone can select a proper SIM card according to the internet surfing requirement and the bandwidths of the first SIM card and the second SIM card, thereby meeting the current internet surfing requirement and improving the experience of the user.

In addition, the mobile phone simultaneously uses the first SIM card and the second SIM card to carry out the internet access service, so that the dual-channel service data transmission of the mobile phone in the DSDS mode can be realized, the mobile phone can more fully and accurately utilize the service bearing capacity of the dual cards, namely, the mobile phone can more fully and accurately utilize the bandwidth capacity of the dual cards, higher service quality is provided, and the experience of a user is improved.

For example, for a foreground APP1 in the mobile phone 100, in the process of accessing the internet 300 by the APP1 for the internet access service, if the service quality of the first SIM card used by the mobile phone 100 currently as a default data account for the internet access service does not meet the service data transmission requirement of the current internet access service, that is, does not meet the current internet access requirement, an uplink retransmission behavior of the service data may occur in the mobile phone 100. The service quality of the first SIM card does not meet the service data transmission requirement of the current internet access service, which may be the case that the signal quality of the first SIM card is not good, or the service data volume of the current internet access service is large, and the bandwidth of the first SIM card cannot meet the transmission requirement of the service data.

When the service data uplink retransmission occurs in the mobile phone 100, the mobile phone 100 may exhibit a page stuck phenomenon. For example, the video playing application in the mobile phone 100 may pause playing video, the music playing application may pause playing music, and the browser application may not update the interface.

The uplink retransmission of the service data in the mobile phone 100 is performed by the retransmission timer 1011 according to the preset retransmission time. The retransmission collector 1012 records the start and stop times of the retransmission timer 1011 as a retransmission idle window. In addition, the handset 100 does not retransmit the service data during the retransmission idle window period. If there is a multi-service session in the handset 100, the retransmission collector 1012 may record a plurality of uplink retransmission start-stop times, resulting in a plurality of retransmission idle windows.

In addition, the retransmission collector 1012 may also obtain the number of retransmission sessions according to the number of retransmission Socket (Socket) packets created by the application, where one retransmission Socket packet corresponds to one retransmission session.

The retransmission collector 1012 may send a retransmission idle window and a number of retransmission sessions for uplink retransmission of the traffic data to the modem layer.

The modem layer of the mobile phone 100 includes a first Packet Data Convergence Protocol (PDCP) layer 103A, a first Radio Link Control (RLC) layer 104A, and a first Media Access Control (MAC) layer 105A, which correspond to the first SIM card and are used to implement the mobile communication function of the first SIM card. The modem layer further includes a second packet data convergence protocol layer 103B, a second radio link control layer 104B, and a second medium access control layer 105B corresponding to the second SIM card for implementing a mobile communication function of the second SIM card.

The modem layer also includes a Radio Frequency (RF) module 106 and an Antenna (Antenna, Ant) module 107. The antenna module 107 includes the antenna 1 and/or the antenna 2 of fig. 2 described above. The radio frequency module 106 and the antenna module 107 are used to implement the transmitting and receiving functions of electromagnetic waves in the mobile phone 100, so as to implement the transmitting and receiving functions of service data.

In addition, if the application in the mobile phone 100 accesses the internet 300 through the first SIM card, the service data of the application performing the internet access service is transmitted between the application and the antenna module 107 sequentially through the kernel layer 101, the first network interface card 102A, the first packet data convergence protocol layer 103A, the first radio link control layer 104A, the first media access control layer 105A, and the radio frequency module 106. If the application in the mobile phone 100 accesses the internet 300 through the second SIM card, the service data of the application performing the internet access service is transmitted between the application and the antenna module 107 sequentially through the kernel layer 101, the second network interface card 102B, the second packet data convergence protocol layer 103B, the second radio link control layer 104B, the second media access control layer 105B, and the radio frequency module 106.

Further, the modem layer includes a first Bandwidth (BW) Detector 108A corresponding to the first SIM card, and a second bandwidth Detector 108B corresponding to the second SIM card. For example, the first bandwidth detector 108A corresponding to the first SIM card serving as the default data account may detect the first bandwidth of the first SIM card in real time along with the internet access service of the first SIM card. The second bandwidth detector 108B corresponding to the second SIM card as the non-default data account may detect the second bandwidth of the second SIM card through the detection service data as the radio frequency resource when the preset bandwidth detection condition is satisfied. The bandwidth detection condition may mean that the service quality of the first SIM card cannot meet the service data transmission requirement of the current internet access service.

The first bandwidth finder 108A may obtain the first bandwidth determination information sequentially through the first packet data convergence protocol layer 103A, the first radio link control layer 104A, the first media access control layer 105A, and the radio frequency module 106, and determine the first bandwidth of the first SIM card according to the first bandwidth determination information. The second bandwidth finder 108B may obtain the second bandwidth determination information sequentially through the second packet data convergence protocol layer 103B, the second radio link control layer 104B, the second media access control layer 105B, and the radio frequency module 106, and determine the second bandwidth of the second SIM card according to the second bandwidth determination information. The first bandwidth determination information and the second bandwidth determination information may be radio resource scheduling information during transmission of the traffic data. The process of determining the bandwidth of the corresponding SIM card by the first bandwidth finder 108A and the second bandwidth finder 108B will be described in detail later.

The modem layer further comprises a first processing module 109. The first processing module 109 is configured to receive a retransmission idle window and a number of retransmission sessions (as an example of an uplink service data transmission parameter, that is, as an example of service quality information) sent by the kernel layer 101, and determine whether a preset bandwidth detection condition is currently met according to the retransmission idle window and the number of retransmission sessions. If the first bandwidth and the second bandwidth of the first SIM card are met, the first processing module 109 obtains the first bandwidth of the first SIM card from the first bandwidth detector 108A and obtains the second bandwidth of the second SIM card from the second bandwidth detector 108B, and determines the SIM card for performing the internet access service according to the first bandwidth and the second bandwidth. The mobile phone 100 transmits service data according to the determined data channel corresponding to the SIM card for performing the internet access service.

In this implementation, the modem layer may also be referred to as a hardware layer.

It should be noted that, in another implementation manner of the present application, the aforementioned function of the first processing module 109 may be implemented by the aforementioned processor 110.

The Mobile network (Mobile Net)200 includes a first Cell (Cell)201A included in an access network corresponding to the first SIM card, and a first Core Network (CN) 202A corresponding to the first Cell 201A, where the first Cell 201A and the first Core network 202A are configured to provide a wireless network for the Mobile phone 100 to access the internet 300 through the first SIM card. The mobile network 200 further includes a second cell 201B included in the access network corresponding to the second SIM card, and a second core network 202B corresponding to the second cell 201B, where the second cell 201B and the second core network 202B are configured to provide a wireless network for the mobile phone 100 to access the internet 300 through the second SIM card. In addition, the access network corresponding to the first SIM card further includes a first Base Station (BS) (not shown), and the access network corresponding to the second SIM card further includes a second Base Station (not shown).

Internet 300 includes a plurality of servers such as server (server) 301, server 302, and server 303. The servers such as the server 301, the server 302, and the server 303 may be application servers providing application support corresponding to the applications such as APP1, APP2, APP3 in the mobile phone 100.

Referring to fig. 4A, in combination with the above fig. 3, the service processing method applied to the mobile phone 100 provided by the present application includes the following steps:

s100, the mobile phone 100 is powered on and activated to respectively activate data connections of the first SIM card and the second SIM card, for example, activate PDP connections of the first SIM card and the second SIM card in 2G and 3G networks, or activate PDN connections of the first SIM card and the second SIM card in 4G networks. And the mobile phone 100 creates a first data channel for the first SIM card and a second data channel for the second SIM card, where the first data channel and the second data channel may be IP data channels, respectively. The mobile phone 100 defaults to the first SIM card as a default data account for performing the internet access service.

S200, the mobile phone 100 uses the first SIM card to perform an internet access service, i.e. uses the first data channel corresponding to the first SIM card to transmit service data. The retransmission collector 1012 in the mobile phone 100 obtains the retransmission idle window and the number of retransmission sessions (as an example of the uplink service data transmission parameter, that is, as an example of the service quality information) of the uplink retransmission of the service data in the process of performing the internet access service by the first SIM card, and sends the retransmission idle window and the number of retransmission sessions to the first processing module 109. The first bandwidth detector 108A in the handset 100 detects the first bandwidth BW1 of the first SIM card in real time.

The acquiring, by the retransmission collector 1012 in the mobile phone 100, the retransmission idle window and the retransmission session number of the uplink retransmission of the service data in the process of the internet service performed by the first SIM card includes: for foreground applications in the mobile phone 100, such as APP1, APP1, during the process of accessing the internet 300, when the APP1 accesses the internet service data of the internet service of the internet 300 and performs uplink retransmission, the retransmission collector 1012 in the mobile phone 100 records the uplink retransmission start-stop time of the retransmission timer 1011 as a retransmission idle window. The retransmission idle window is a period of time information.

If there is a multi-service session, the retransmission collector 1012 may record a plurality of uplink retransmission start-stop times, resulting in a plurality of retransmission idle windows.

In addition, the retransmission collector 1012 may obtain the number of retransmission sessions according to the number of retransmission Socket (Socket) packets created by the APP1, where one retransmission Socket packet corresponds to one retransmission session.

The retransmission collector 1012 sends the recorded retransmission idle window and the number of retransmission sessions to the first processing module 109 in the handset 100 in real time or according to a preset sending period. The transmission period may range from 1s to 5s, and may be, for example, 1s, 2.5s, 4s, 5s, or the like. Of course, the transmission period may have other values.

The calculation of the bandwidth can be determined according to the uplink and downlink newly-transmitted scheduling condition when the SIM card performs the internet access service, where the uplink and downlink newly-transmitted scheduling condition is the wireless resource scheduling information in the uplink service data transmission and downlink service data transmission processes. The radio resource scheduling information includes information such as a scheduling request response time tr, a Transport Block Size (TBS), a scheduling padding (padding) ratio rp, and a scheduling time density d. The scheduling request response time tr refers to the time from the time when the SIM card sends the scheduling request to the time when the SIM card receives the response of the access network, and the access network refers to the network including the cell and the core network provided by the base station corresponding to the SIM card. Scheduling TBS refers to the size of a data block that the access network allows the SIM card to transmit this time. The scheduled padding ratio rp is a ratio of the data amount applied by the SIM card to the data amount allowed to be transmitted by the SIM card by the access network, for example, the data amount applied by the SIM card is 10 bytes (bytes), the data amount allowed to be transmitted by the SIM card by the access network is 100bytes, and the scheduled padding ratio rp is 10%. The scheduling time density d refers to the number of times of access network replies received within a preset reply time after the scheduling request is sent from the SIM card. The radio resource scheduling information may also include other information. The bandwidth calculation process monopolizes the radio frequency resource of the SIM card, and the calculated bandwidth is prevented from being interfered by radio frequency switching, so that the bandwidth calculation is accurate.

In the process that the mobile phone 100 uses the first SIM card to perform the internet access service, the process that the first bandwidth detector 108A in the mobile phone 100 detects the first bandwidth BW1 in real time along with the transmission of the service data includes: the first bandwidth finder 108A acquires service data as a radio frequency resource and sends a scheduling request to the access network. The first bandwidth finder 108A then calculates a first bandwidth BW1 from the radio resource scheduling information for the traffic data transmission.

Exemplary, the first bandwidth BW1 is calculated as follows:

BW1＝R(tr1)×F(TBS1，rp1，d1)

where tr1 is the first scheduling request response time, TBS1 is the first scheduling TBS, rp1 is the first scheduling padding fraction, and d1 is the first scheduling time density.

In addition, R (tr1) is an inverse correlation function and F (TBS1, rp1, d1) is a positive correlation function. Wherein the shorter the first scheduling request response time tr1, the larger the scheduling TBS1, the larger the scheduling filler fraction rp1, the higher the scheduling time density d1, and the larger the first bandwidth BW 1.

In one implementation of the present application, R (tr1) ═ 1/(Q × tr1+ T), where Q is a constant coefficient, which may be set according to the scheduling request response time tr of different SIM cards. The value range of Q is more than or equal to 0.9 and less than 1. Of course, the value of Q may be set as needed. T is an offset constant, the value of which can be specifically set as required.

In one implementation of the present application, F (TBS1, rp1, d1) ═ H × TBS1 × rp1 × d 1. Wherein H is a constant coefficient, and can be determined according to the scheduling TBS, the scheduling padding ratio rp, and the scheduling time density d of different SIM cards. The value range of H can be that H is more than or equal to 0.9 and less than 1. Of course, the value of H may be set according to other needs.

Of course, in other implementations of the present application, R (tr1) and F (TBS1, rp1, d1) may be other forms of functions.

In this implementation, the detection of the first bandwidth BW1 by the first bandwidth detector 108A is performed at the modem layer, and the first bandwidth detector 108A may calculate the first bandwidth BW1 according to the above radio resource scheduling information in the first medium access control layer 105A, so that the detection time overhead of the first bandwidth BW1 is very small, usually lower than 1 s.

S300, after receiving the idle retransmission window and the number of retransmission sessions sent by the retransmission collector 1012, the first processing module 109 in the mobile phone 100 determines the service quality of the first SIM card according to the idle retransmission window and the number of retransmission sessions, and determines whether the current service quality meets the preset bandwidth detection condition. If the bandwidth detection condition is satisfied, the mobile phone 100 performs S400, and if the bandwidth detection condition is not satisfied, the mobile phone 100 performs S200.

In an implementation manner of the present application, the first processing module 109 may determine the detection window according to the received retransmission idle window. For example, if the number of the retransmission idle windows received by the first processing module 109 within the preset statistical time is only 1, the first processing module 109 determines that the retransmission idle window is the probing window. If there are multiple idle retransmission windows received by the first processing module 109 within the preset statistical time, the first processing module 109 determines an intersection of the idle retransmission windows as a detection window.

In addition, if there is no common intersection between the multiple retransmission idle windows, it is considered that the network congestion of the first SIM card is severe at this time, and the first processing module 109 may select a smallest retransmission idle window from the multiple retransmission idle windows as the detection window, or select a smallest intersection as the detection window, or may also arbitrarily select a retransmission idle window as the detection window.

The preset statistical time can be 1 s-30 s, for example, 1s, 8.5s, 10s, 30s, etc.; of course, the statistical time may be other values.

If the first processing module 109 determines that the detection window is greater than the detection window threshold, the first processing module 109 obtains, from the first packet data convergence protocol layer 103A of the first SIM card, a density rate of downlink service data in the first packet data convergence protocol layer 103A (as an example of a downlink service data transmission parameter, that is, as an example of service quality information), where the density rate of the downlink service data refers to a size of the downlink service data, which is received by the first packet data convergence protocol layer 103A, sent by the internet 300 in a unit time, and a unit of the downlink service data is Bytes/s. The lower the density rate of the downlink service data is, the slower the transmission rate of the downlink service data packet is, that is, the insufficient downlink bandwidth of the first SIM card is indicated, which cannot meet the internet access requirement of the application.

If the first processing module 109 determines that the density rate of the downlink service data in the first packet data convergence protocol layer 103A is lower than the density rate threshold, the first processing module 109 determines that the service quality of the current first SIM card is not good, and the bandwidth detection condition is satisfied. The handset 100 executes S400.

The value range of the detection window threshold value can be 0.3 s-0.6 s, for example, 0.3s, 0.45s, 0.5s, 0.6s, and the like; of course, the detection window threshold may be other values.

The value range of the density rate threshold value can be 800 Bytes/s-1100 Bytes/s, such as 800Bytes/s, 900Bytes/s, 1050Bytes/s, 1100Bytes/s, and the like; of course, the density rate threshold may be other values.

In another implementation manner of the present application, if it is determined that the number of retransmission sessions received within the preset statistical time is greater than the retransmission session number threshold, the first processing module 109 obtains the density rate of the downlink service data in the first packet data convergence protocol layer 103A of the first SIM card. If the density rate of the downlink service data in the first packet data convergence protocol layer 103A of the first SIM card is lower than the density rate threshold, the first processing module 109 considers that the data account adjustment condition is currently satisfied. The handset 100 performs S400.

The value range of the retransmission session number threshold value can be 3-10, for example, 3, 5, 8, 10, etc.; of course, the retransmission session number threshold may be other values.

In another implementation manner of the present application, if it is determined that the ratio of the number of retransmission sessions received within the preset statistical time is greater than the threshold value of the ratio of the number of retransmission sessions, the first processing module 109 obtains the density rate of the downlink service data in the first packet data convergence protocol layer 103A of the first SIM card. If the density rate of the downlink service data in the first packet data convergence protocol layer 103A of the first SIM card is lower than the density rate threshold, the first processing module 109 considers that the data account adjustment condition is currently satisfied. The cellular phone 100 executes S14.

The retransmission session number ratio is the ratio of the number of received retransmission sessions in a preset counting time and the total number of sessions occurring in the counting time. The value range of the retransmission session number ratio threshold may be 40% to 100%, for example, 40%, 50%, 66%, 100%, and the like; of course, the retransmission session number ratio threshold may be other values.

S400, the second bandwidth detector 108B in the handset 100 detects the second bandwidth BW2 of the second SIM card.

The process of second bandwidth finder 108B detecting the second bandwidth of the second SIM card includes second bandwidth finder 108B constructing one or more probe traffic data based on a local destination IP of the mobile network of the second SIM card. The destination IP may be, for example, an IP of a local Domain Name System (DNS) server, an IP of a local Secure User Plane Location (SUPL) server, an IP of the aforementioned second core network 202B, or other virtual IP that does not correspond to a specific server.

Illustratively, the probe traffic data includes the IP of the second core network 202B. The second bandwidth detector 108B sends the detection service data, which is used as the radio frequency resource, through the second data channel of the second SIM card in the detection window period. Further, the second bandwidth finder 108B determines the second bandwidth BW2 of the second SIM card according to the uplink and downlink new transmission scheduling of the second media access control layer 105B.

The calculation of the second bandwidth BW2 is similar to the calculation of the first bandwidth BW1, and is specifically as follows:

BW2＝R(tr2)×F(TBS2，rp2，d2)

where tr2 is the second scheduling request response time, TBS2 is the second scheduling TBS, rp2 is the second scheduling padding fraction, and d2 is the second scheduling time density.

In one implementation of the present application, R (tr2) ═ 1/(Q × tr2+ T), where Q is a constant coefficient, which may be set according to the scheduling request response time tr of different SIM cards. The value range of Q is more than or equal to 0.9 and less than 1. Of course, the value of Q may be set as needed. T is an offset constant, the value of which can be specifically set as required.

In one implementation of the present application, F (TBS2, rp2, d2) ═ H × TBS2 × rp2 × d 2. Wherein H is a constant coefficient, and can be determined according to the scheduling TBS, the scheduling padding ratio rp, and the scheduling time density d of different SIM cards. The value range of R can be more than or equal to 0.9 and less than 1. Of course, the value of H may be set according to other needs.

Of course, in other implementations of the present application, R (tr2) and F (TBS2, rp2, d2) may be other forms of functions.

In this implementation, the detection of the second bandwidth BW2 by the second bandwidth detector 108B is performed at the modem layer, and the second bandwidth BW2 is calculated according to the radio resource scheduling information in the second media access control layer 105B, so that the detection time overhead of the second bandwidth BW2 is very small, usually lower than 1s, and the bandwidth of the second SIM card can be quickly and accurately detected.

In addition, the second SIM card sends the probe service data to probe the second bandwidth BW2 in the probe window period determined according to the retransmission idle window, and since the service of the first SIM card serving as the default data account is idle or has poor service quality, the probe service data serving as the radio frequency resource is switched to the second SIM card for short-term probing, so that the influence on the internet access service of the first SIM card is not large. In addition, the detection service data is sent to the local IP of the second SIM card, so that the flow charging of the second SIM card cannot be increased.

S500, the first processing module 109 in the mobile phone 100 obtains the first bandwidth BW1 of the first SIM card from the first bandwidth probe 108A, obtains the second bandwidth BW2 of the second SIM card from the second bandwidth probe 108B, and determines the SIM card for performing the internet surfing service according to the first bandwidth BW1 and the second bandwidth BW 2.

Referring to fig. 4B, in an implementation manner of the present application, the process of determining, by the first processing module 109, a SIM card for performing internet access service according to the first bandwidth BW1 and the second bandwidth BW2 includes the following steps:

s501, the handset 100 determines whether the first bandwidth BW1 and the second bandwidth BW2 satisfy BW1 ≧ nxbw 2. If so, the mobile phone 100 performs S504, otherwise, the mobile phone performs S502. Wherein N is an arbitrary number greater than 1, for example, the value range of N may be 2 to 15, for example, 2, 5, 10, 12.5, 15, and the like; of course, the value of N may be other values.

The first processing module 109 in the mobile phone 100 performs bandwidth calculation, and if the BW1 is greater than or equal to nxbw 2, it is considered that the first bandwidth BW1 of the first SIM card is much greater than the second bandwidth BW2 of the second SIM card, the first SIM card can provide better service quality compared with the second SIM card, and the first processing module 109 determines to continue to use the first SIM card for the internet access service, i.e., to use the first data channel of the first SIM card for the transmission of the service data.

S502, the handset 100 determines whether the first bandwidth BW1 and the second bandwidth BW2 satisfy BW2 ≧ nxbw 1. If so, the mobile phone 100 performs S505, and if not, the mobile phone performs S503.

If the BW2 is greater than or equal to nxbw 1, the first processing module 109 determines that the second bandwidth BW2 of the second SIM card is much greater than the first bandwidth BW1 of the first SIM card, the second SIM card can provide better service quality compared with the first SIM card, and the first processing module 109 determines to use the second SIM card for the internet access service, that is, to use the second data channel of the second SIM card for the transmission of the service data.

S503, the mobile phone 100 calculates the synthesized bandwidth to obtain the synthesized bandwidth K (BW1) × BW1+ K (BW2) × BW 2. The mobile phone 100 determines whether or not K (BW1) × BW1+ K (BW2) × BW2 ≧ N × BW 1. If so, the mobile phone 100 performs S506, otherwise, the mobile phone performs S504.

If K (BW1) × BW1+ K (BW2) × BW2 is greater than or equal to nxbw 1, the first processing module 109 determines that the internet surfing service performed by using the first SIM card and the second SIM card simultaneously can provide a larger internet surfing bandwidth, improve the internet surfing speed, that is, improve the internet surfing service quality, and improve the internet surfing experience of the user, compared with the case of performing the internet surfing service by using only the first SIM card or only the second SIM card. The first processing module 109 determines that the first SIM card and the second SIM card are used simultaneously for performing the internet access service, and the first data channel and the second data channel are used simultaneously for transmitting the service data, so that the two data channels are used simultaneously for transmitting the service data, and the effect of the DSDA mode can be achieved.

S504, the mobile phone 100 determines to continue to use the first SIM card for the internet access service, that is, to use the first data channel corresponding to the first SIM card for transmitting the service data.

S505, the mobile phone 100 determines to use the second SIM card to perform the internet access service, i.e., to use the second data channel corresponding to the second SIM card to perform service data transmission.

S506, the mobile phone 100 determines to use the first SIM card and the second SIM card to perform the internet access service, that is, to use the first data channel and the second data channel to perform service data transmission.

In this implementation, k (bw) is a scaling factor function inversely related to the bandwidth of the user card due to DSDS user card switching (e.g., rf switching overhead during user card switching). When the bandwidth is close to the peak bandwidth, the value of k (bw) is about 0.3, and as the bandwidth decreases, the value of k (bw) gradually increases, and the switching overhead influence of the cell phone 100 on receiving and sending the service data decreases after the data density per unit time decreases.

In one implementation of the present application, k (BW) ═ 2^ (-BW) + P × BW/(BW +1), BW is the bandwidth evaluated by each SIM card individually, P is the convergence coefficient, and P may be 0.3 as described above.

Then K (BW1) ═ 2^ (-BW1) + P × BW1/(BW1+1), K (BW2) ═ 2^ (-BW2) + P × BW2/(BW2+ 1).

Of course, in other implementations of the present application, k (bw) may be other forms of functions.

When the mobile phone 100 uses the first SIM card and the second SIM card to perform the internet access service, the current service data in the mobile phone 100 may be continuously transmitted through the first data channel corresponding to the first SIM card. The new service data in the mobile phone 100 may be transmitted through the second data channel corresponding to the second SIM card.

Or, the mobile phone 100 may select a part of the current service data to continue to be transmitted through the first data channel corresponding to the first SIM card, and another part of the current service data to be transmitted through the second data channel corresponding to the second SIM card. For example, the size of the service data may be determined according to the bandwidth sizes of the first SIM card and the second SIM card, where the SIM card with a larger bandwidth undertakes more transmission of the service data, and the SIM card with a smaller bandwidth undertakes less transmission of the service data.

Of course, the mobile phone 100 may also use the first SIM card and the second SIM card simultaneously to transmit service data in other manners, such as sorting according to applications.

In this implementation, since the mobile phone 100 includes two data channels, the dual card switching is faster and more convenient, which can effectively avoid service interruption and improve the internet experience of the user. In addition, in the implementation manner, the selected SIM card for performing the internet access service is an SIM card with a larger bandwidth, which can provide a larger internet access bandwidth, i.e., provide a better internet access quality.

In some implementation manners of the present application, for S510, after the mobile phone 100 determines the SIM card for performing the internet surfing service, the mobile phone 100 may further display a prompt message on a display interface of the mobile phone 100 for prompting the user to perform the switching of the SIM card for the internet surfing service. For example, when switching from the first SIM card to the second SIM card for internet access, the display interface of the mobile phone 100 displays "switched to the second SIM card for internet access". When the first SIM card is switched to the second SIM card for internet access, a prompt message "switched to dual-card internet access" is displayed on the display interface of the mobile phone 100.

Referring to fig. 4C, in an implementation manner of the present application, a process of determining, by the mobile phone 100, a SIM card for performing internet access service according to the first bandwidth BW1 and the second bandwidth BW2 includes the following steps:

s501', the handset 100 determines whether the first bandwidth BW1 and the second bandwidth BW2 satisfy BW1 ≧ N1 × BW 2. If so, the mobile phone 100 performs S504, otherwise, the mobile phone performs S502'.

The value range of N1 can be 2-15, for example, 2, 5, 10, 12.5, 15, etc.; of course, the value of N1 may be other values.

S502', the handset 100 determines whether the first bandwidth BW1 and the second bandwidth BW2 satisfy BW2 ≧ N2 × BW 1. If so, the mobile phone 100 performs S505, otherwise, the mobile phone performs S503'.

The value range of N2 can be 3-16, for example, 3, 6, 11, 13, 16, etc.; of course, the value of N2 may be other values.

S503', the mobile phone 100 performs the calculation of the synthesized bandwidth to obtain the synthesized bandwidth K (BW1) × BW1+ K (BW2) × BW 2. The mobile phone 100 determines whether or not K (BW 1). times.BW 1+ K (BW 2). times.BW 2 is N3. times.BW 1. If so, the mobile phone 100 performs S506, otherwise, the mobile phone performs S504.

The value range of N3 can be 4-17, for example, 4, 7, 12, 15.5, 17, etc.; of course, the value of N3 may be other values.

S504, the mobile phone 100 determines to continue to use the first SIM card for the internet access service, i.e., to use the first data channel of the first SIM card for transmitting the service data.

S505, the mobile phone 100 determines to use the second SIM card to perform the internet access service, i.e., to use the second data channel of the second SIM card to perform the service data transmission.

In this implementation, N1 < N2 < N3. Of course, N1, N2, and N3 may be any other number different from 1.

In the service processing method applied to the mobile phone 100 in the DSDS mode provided by this implementation manner, after the mobile phone 100 is started up, the mobile phone 100 creates a first data channel for a first SIM card in the mobile phone 100 and a second data channel for a second SIM card, which may facilitate the mobile phone 100 to perform SIM card switching. In the process of performing the internet access service by the mobile phone 100, the mobile phone 100 may quickly and accurately detect the first bandwidth BW1 of the first SIM card and the second bandwidth BW2 of the second SIM card, and may conveniently and accurately determine the SIM card performing the internet access service according to the first bandwidth BW1 and the second bandwidth BW2, and transmit service data by using the data channel corresponding to the SIM card determining the internet access service. The SIM card for the internet access service is determined or decided more quickly, and the SIM card for the internet access service determined according to the bandwidth can provide better bandwidth for a user, namely better service quality. In addition, the mobile phone 100 in the DSDS mode can also implement the concurrent dual-card internet access service, and the service quality of the mobile phone 100 in the DSDS mode can be effectively improved.

In the service processing method applied to the mobile phone 100 in the DSDS mode provided by this implementation manner, even if the default data account selected by the user is the first SIM card, the mobile phone 100 can use the second SIM card to perform the internet access service.

In another implementation manner of the application, for the aforementioned S200, if the retransmission collector 1012 determines that the service quality of the current first SIM card is not good according to the number of retransmission sessions, the retransmission collector 1012 may also send only a retransmission idle window for uplink service data retransmission to the first processing module 109 in the modem layer.

In another implementation of the application, for the foregoing S200, in the process that the mobile phone 100 uses the first SIM card to perform the internet access service, the first bandwidth detector 108A in the mobile phone 100 may not detect the first bandwidth BW1 of the first SIM card in real time. If the handset 100 executes S300 to determine that the bandwidth detection condition is satisfied, for S400, the first bandwidth detector 108A in the handset 100 may first detect the first bandwidth BW1 of the first SIM card, and then the second bandwidth detector 108B in the handset 100 detects the second bandwidth BW2 of the second SIM card.

In another implementation manner of the application, for the aforementioned S100, after the mobile phone 100 is powered on and started, only the PDN connection or the PDP connection of the first SIM card may be activated, and a first data channel is created for the first SIM card. After the mobile phone 100 executes S300, and it is determined that the bandwidth detection condition is satisfied, the mobile phone 100 reactivates the PDN connection or the PDP connection of the first SIM card, and creates a second data channel for the second SIM card. The handset 100 then executes S400.

Referring to fig. 5, fig. 5 is a schematic diagram showing the cellular download rate of different types of mobile phones under different card-using states, wherein the abscissa is the detection time (T); the ordinate is the cellular download rate in Bytes/s. For a single-card mobile phone with only one SIM card, when the single-card mobile phone downloads the service data in the internet service, the single-card mobile phone downloads the service data by using the single card, and the single-cell download rate of the single-card mobile phone is shown as line L1. For the mobile phone 100 provided in the present application, when the mobile phone 100 uses the first SIM card as the default data account and only uses the first SIM card for downloading service data, the single-cell download rate of the mobile phone 100 is shown as the line L2. When the mobile phone 100 only uses the second SIM card for internet access service, i.e. only uses the second SIM card for downloading the service data, the single-cell download rate of the mobile phone 100 is shown as line L3. The mobile phone 100 simultaneously uses the first SIM card and the second SIM card to perform the internet access service, and when the first SIM card and the second SIM card are used to perform the downloading of the service data, the dual-cellular download rate is as shown by line L4 under the condition that the dual-card air interface of the mobile phone 100 is limited, so that the mobile phone 100 in the DSDS mode simultaneously performs the internet access service on the first SIM card and the second SIM card, and the dual-card integrated cellular download rate is significantly higher than the cellular download rate of a single card, so that the service carrying capacity of the dual cards can be effectively utilized, the cellular download rate is improved, a higher service quality is provided, and the user experience can be effectively improved. In addition, line L4 is the measured dual-card converged cellular download rate under the ideal situation of analog dual-card air interface limitation.

In another implementation manner of the present application, if the mobile phone 100 is stuck during the process of using the second SIM card to perform the internet access service, the mobile phone 100 may further obtain the current bandwidth of the second SIM card and the current bandwidth of the first SIM card, and re-determine the SIM card for performing the internet access service according to the bandwidths.

In addition, in another implementation manner of the present application, after the SIM card for performing the internet access service is switched from the first SIM card to the second SIM card, the SIM card for performing the internet access service may also be directly switched to the first SIM card again after a preset switching time. The range of the switching time can be 20s to 60s, for example, 20s, 30s, 45.5s, 60s, and the like; of course, the switching time may be other values.

It should be noted that, in the present application, the mobile phone 100 may detect the bandwidth of the SIM card performing the internet access service in real time during the process of performing the internet access service by the SIM card. The mobile phone 100 may obtain the bandwidth of the SIM card not performing the internet access service by sending the detection service data when the SIM card currently performing the internet access service is stuck. In the whole internet access process, the mobile phone 100 may switch the SIM card for performing the internet access service according to the real-time bandwidths of the first SIM card and the second SIM card.

In other implementation manners of the present application, the density rate of the downlink traffic data may also be other downlink traffic data transmission parameters used for indicating a downlink traffic transmission condition, such as the number of downlink traffic data in a preset time (for example, a downlink traffic data packet of 100Bytes is received in 2s), or the number of downlink traffic data packets transmitted in a unit time (for example, the number of downlink traffic data packets transmitted in a unit time is 5), and may be selected as needed. The above-mentioned retransmission idle window, number of retransmission sessions, and ratio of retransmission sessions may be other uplink traffic data transmission parameters indicating the uplink traffic transmission situation. Which can be set as desired.

In another implementation manner of the application, for the foregoing S200, in the process that the mobile phone 100 uses the first SIM card to perform the internet access service, the mobile phone 100 may also obtain the signal quality of the first SIM card (as an example of the service quality information). As for the foregoing S300, it may be determined by the handset 100 whether the bandwidth detection condition is satisfied according to the signal quality information of the first SIM card. For example, if the signal quality of the first SIM card is lower than 40% of the normal signal quality, the signal quality is considered to be poor, and the bandwidth detection condition is satisfied. If the bandwidth detection condition is satisfied, the mobile phone 100 executes S400 to detect the second bandwidth of the second SIM card. Otherwise, the signal quality is considered to be better, the bandwidth detection condition is not met, the second bandwidth of the second SIM card does not need to be detected, and the first SIM card is continuously used for the internet access service.

In other implementations of the application, for the foregoing S200 and S300, the mobile phone 100 may also determine the service quality condition according to one or more of the network access technology of the first SIM card, the service data volume information of the internet access service performed by the first SIM card, and the bandwidth of the first SIM card (as an example of the service quality information), so as to determine whether the foregoing bandwidth detection condition is satisfied, that is, determine whether the current service quality satisfies the internet access requirement. For example, if the network access technology of the first SIM card is 2G or 3G, the service quality is considered to be poor, and the bandwidth detection condition is satisfied, the mobile phone 100 executes S400 to detect the second bandwidth of the second SIM card, and needs to perform SIM card adjustment. If the bandwidth is 4G or 5G, the service is considered to be better, the bandwidth detection condition is not met, the second bandwidth does not need to be detected, and the first SIM card is continuously used for the internet access service.

In other implementation manners of the application, the mobile phone 100 may further determine whether the service quality of the first SIM card meets the current internet access requirement according to one or more of other information such as the currently running application type and the number of applications in the mobile phone 100. And when the current internet access requirement is not met, the mobile phone 100 executes S400 to detect the second bandwidth of the second SIM card. When the current internet access requirement is met, the mobile phone 100 continues to use the first SIM card for internet access service.

In other implementation manners of the application, the mobile phone 100 may also determine, according to the service quality information, that a bandwidth detection condition is satisfied, then respectively obtain a first bandwidth of the first SIM card and a second bandwidth of the second SIM card, and determine whether to switch the SIM cards according to sizes of the first bandwidth and the second bandwidth.

In other implementations of the application, the mobile phone 100 may also detect a first bandwidth of the first SIM card and a second bandwidth of the second SIM card according to a preset bandwidth detection period, and determine whether to adjust the SIM card according to the sizes of the first bandwidth and the second bandwidth. The value range of the bandwidth detection period may be 0.5h to 2h, for example, 0.5h, 1h, 1.4h, 2h, and the like. Of course, the bandwidth sounding period may be any other value.

In another implementation manner of the present application, when the mobile phone 100 switches the SIM card for performing the internet access service, the display interface of the mobile phone 100 may not display any prompt information related to the SIM card switching, so that the user is insensitive to the SIM card switching.

In another implementation manner of the present application, when the mobile phone 100 switches the SIM card for performing the internet access service, the display interface of the mobile phone 100 may also display the user card identification information for reminding the user of the currently used user card.

Referring to fig. 6A, the mobile phone 100 displays identification information M1 of the first SIM card and identification information M2 of the second SIM card, wherein the identification information M1 of the first SIM card includes an internet access identifier (e.g., an up-down arrow). The user may determine that the SIM card currently performing the internet access service of the mobile phone 100 is the first SIM card through the identification information M1.

Referring to fig. 6B, if the mobile phone 100 switches the SIM card for performing the internet access service to the second SIM card, the mobile phone 100 may display a prompt message M3 indicating that "the mobile phone has switched to using the second SIM card for internet access". In addition, the identification information M2 of the second SIM card includes an internet access identification (e.g., up and down arrows).

Referring to fig. 6C, if the mobile phone 100 uses the first SIM card and the second SIM card to perform the internet access service, the mobile phone 100 may display a prompt message M4 indicating that "the mobile phone has switched to using the dual cards to access the internet". In addition, the identification information M1 of the first SIM card and the identification information M2 of the second SIM card both include an internet access identifier (e.g., up and down arrows).

In other implementations of the present application, the mobile phone 100 may also display other types of identification information M1 of the first SIM card and identification information M2 of the second SIM card, and other types of prompt information, which may be selected as needed.

In an implementation manner of the present application, after the mobile phone 100 is powered on and started, the mobile phone 100 executes the service processing method provided in the present application, that is, when the quality of the first SIM card is not good, the mobile phone 100 performs the automatic switching of the SIM card for performing the internet access service.

In another implementation manner of the present application, if the mobile phone 100 detects that the user starts the smart switching internet access card control under the SIM card management control, the mobile phone 100 executes the service processing method provided in the present application to perform the automatic switching of the SIM card for performing the internet access service.

Referring to fig. 7, the present application also provides a communication system including a mobile phone 400, a mobile network (mobilene) 200 and the Internet (Internet) 300. In contrast to the handset 100 shown in fig. 3, the core layer 101 of the handset 400 further comprises a second processing module 1013. In addition, the modem layer of the handset 400 does not include the aforementioned first processing module 109.

The retransmission collector 1012 of the handset 400 may send the aforementioned retransmission idle window and retransmission session number of the uplink service data retransmission to the second processing module 1013. The second processing module 1013 determines whether the current bandwidth detection condition is met according to the retransmission idle window and the number of retransmission sessions. If the bandwidth detection condition is met, the second processing module 1013 acquires a first bandwidth of the first SIM card from the first bandwidth detector 108A and a second bandwidth of the second SIM card from the second bandwidth detector 108B, respectively, and determines the SIM card for performing the internet access service according to the first bandwidth and the second bandwidth. The mobile phone 400 transmits service data according to the determined data channel corresponding to the SIM card for performing the internet access service.

It should be noted that, in another implementation manner of the present application, the function of the second processing module 1013 may be implemented by the aforementioned processor 110.

Referring to fig. 8, in combination with the above fig. 7, the service processing method applied to the mobile phone 400 provided by the present application includes the following steps:

s110, the mobile phone 400 is powered on and started, and the data session functions of the first SIM card and the second SIM card are respectively activated, for example, the PDP connection of the first SIM card and the second SIM card is activated in the 2G network and the 3G network, or the PDN connection network of the first SIM card and the second SIM card is activated in the 4G network. And the mobile phone 400 creates a first data channel for the first SIM card and a second data channel for the second SIM card, where the first data channel and the second data channel may be IP data channels, respectively. The mobile phone 400 defaults to the first SIM card as a default data account for performing the internet access service, and transmits service data using the first data channel corresponding to the first SIM card.

S210, the mobile phone 400 uses the first SIM card to perform the internet access service, and the retransmission collector 1012 in the mobile phone 400 obtains a retransmission idle window and a retransmission session number of uplink service data retransmission during the internet access service performed by the first SIM card, and detects the first bandwidth BW1 of the first SIM card in real time.

For S210, different from the foregoing S200, the retransmission collector 1012 in the handset 400 sends the retransmission idle window and the number of retransmission sessions of the uplink service data retransmission to the second processing module 1013. Other contents of S210 are the same as or similar to S200, and are not described herein again.

S310, after the second processing module 1013 in the mobile phone 400 receives the retransmission idle window and the number of retransmission sessions sent by the retransmission collector 1012, determines a service quality condition of the first SIM card to determine whether the first SIM card currently satisfies a bandwidth detection condition.

For example, the second processing module 1013 determines the detection window according to the retransmission idle window within the preset statistical time. The second processing module 1013 determines the ratio of the number of retransmission sessions according to the number of retransmission sessions and the number of all sessions within a preset statistical time.

If the second processing module 1013 determines that the ratio of the number of retransmission sessions is greater than the threshold value of the ratio of the number of retransmission sessions, the second processing module 1013 acquires the density rate of the downlink service data in the first packet data convergence protocol layer 103A of the first SIM card. If the density rate of the downlink service data in the first packet data convergence protocol layer 103A of the first SIM card is lower than the density rate threshold, the second processing module 1013 determines that the data account adjustment condition is currently satisfied. The handset 400 performs S410. The values of the retransmission session number ratio threshold and the density rate threshold are as described above, and are not described herein again.

S410, the second bandwidth detector 108B in the handset 400 detects the second bandwidth BW2 of the second SIM card.

The specific implementation of S410 is the same as S400 described above, and is not described herein again.

S510, the second processing module 1013 in the cell phone 400 acquires the first bandwidth BW1 of the first SIM card from the first bandwidth probe 108A, acquires the second bandwidth BW2 of the second SIM card from the second bandwidth probe 108B, and determines the SIM card for performing the internet access service according to the first BW1 and the second BW 2.

The process of determining the SIM card for performing the internet access service by the second processing module 1013 is the same as the process of determining the SIM card for performing the internet access service by the first processing module 109, and is not described herein again.

In addition, the service processing method can also be applied to electronic devices based on non-3GPP Networks such as Wireless Local Area Networks (WLAN) and Wireless internet access (WiFi), or other types of Networks.
