The following embodiments describe it.

An embodiment of the present invention provides a network connection method, the flow diagram of which is shown in Figure 1, specifically including:

Step S101: when it is detected that the predetermined process for the second identity recognition module is started, obtain the network-related information of the first identity recognition module that can be reused by the second identity recognition module;

Specifically, the network-related information of the cell corresponding to the first identity recognition module that can be reused by the second identity recognition module is acquired. Wherein, the corresponding cell includes any of the following: the cell where the first identity recognition module is currently located; the neighboring cell of the cell where the first identity recognition module is currently located; the cell measured by the first identity recognition module when performing signal measurement.

That is to say, when it is detected that the predetermined process for the second identity recognition module starts, the network-related information of the cell where the first identity recognition module is currently located that can be reused by the second identity recognition module can be obtained; The network-related information of the adjacent cell of the cell where the first identity recognition module reused by the identity recognition module is currently located; or the network of the cell measured by the first identity recognition module that can be reused by the second identity recognition module during signal measurement can also be obtained Related Information.

In practical applications, the cell measured by the first identity recognition module is processed in the same way as the adjacent cell of the cell where the first identity recognition module is currently located. The cell is introduced as an example, and the situation of the cell measured when the first identity recognition module performs signal measurement will not be repeated.

Wherein, the network-related information includes at least one of cell information, signal quality measurement results, frequency point information, and signal strength information, and the cell information mainly includes the frequency point where the cell is located, common channel parameters, system broadcast messages, and the like.

In practical applications, the method of determining the first identity recognition module that can be reused by the second identity recognition module specifically includes:

Based on the network status of the network to which the other identity recognition modules except the second identity recognition module belong, the first identity recognition module that can be reused by the second identity recognition module is determined from the other identity recognition modules.

The network status includes but not limited to cell signal strength and cell signal reception quality.

The multi-card multi-standby user terminal may include multiple identity recognition modules. When it is detected that a predetermined process for the second identity recognition module starts, for example, the second identity recognition module pre-executes cell search for network registration, or the second identity recognition module Pre-execute cell frequency point scanning for network redirection, or pre-execute inter-system or intra-system measurement by the second identity recognition module for system switching, etc. It is conceivable that other identities in the terminal except the second identity recognition module The identification module can include various states that can reuse network-related information for the second identification module:

The first type: only one identity recognition module has been registered, such as the first identity recognition module, and the network-related information of the cell where the first identity recognition module is currently located or the adjacent cells of the current cell can be directly reused by the second identity recognition module , at this time, it is only necessary to directly acquire the network-related information of the cell where the first identity recognition module is currently located or a neighboring cell of the current cell for establishing a network connection.

The second type: At least two identity recognition modules have been registered, such as the first identity recognition module and the third identity recognition module, and there is only one piece of information related to the network of the cell where the first identity recognition module is currently located or the adjacent cell of the current cell. The information can be directly reused by the second identity recognition module, while the network-related information of the cell where the third identity recognition module and other identity recognition modules are currently located or the adjacent cells of the current cell cannot be directly reused by the second identity recognition module. It only needs to directly acquire the network-related information of the cell where the first identity recognition module is currently located or the adjacent cell of the current cell to establish a network connection.

Third, at least two identity recognition modules have been registered, and the network-related information of the cell where the at least two identity recognition modules are currently located or the adjacent cells of the current cell can be obtained by the second identity recognition module. Select at least two identity recognition modules. As an example, when the two registered identity recognition modules are located in the same cell, the identity recognition module with the highest signal strength in the cell can be selected; or the signal reception quality of the cell with the highest quality can be selected. The identity recognition module; or combine multiple conditions to make a comprehensive judgment, which is not limited here. Taking the selection of the first identity recognition module as an example, the network-related information of the cell where the first identity recognition module is currently located or a neighboring cell of the current cell is obtained for establishing a network connection. When the two registered identity recognition modules are located in different cells, the second identity recognition module can arbitrarily select one of the identity recognition modules to obtain the network-related information of the cell where it is currently located or the adjacent cell of the current cell for establishing a network connect.

It should be noted that the network-related information of the cell where the first identity recognition module is currently located or the adjacent cells of the current cell can be reused by the second identity recognition module. First, the second identity recognition module tries to register with the first identity recognition module The radio access technology RAT of the serving cell where the module is currently located or the radio access technology RAT of the adjacent cell of the cell where the first identity recognition module is currently located or the radio access technology of the cell measured by the first identity recognition module when performing signal measurement The access technology RAT and the network operators to which the first identity recognition module and the second identity recognition module belong need to meet predetermined conditions. Wherein, if the RAT to which the serving cell where the first identity recognition module is currently located is the same as the RAT to which the serving cell that the second identity recognition module is attempting to register belongs to, it can be determined that the first identity recognition module and the second identity recognition module attempt to register On the same radio access technology RAT. The predetermined conditions that the network operator needs to meet include any of the following situations: the first identity recognition module and the second identity recognition module belong to the same network operator; the network operators to which the first identity recognition module and the second identity recognition module belong are in the same Equivalent PLMN (PublicLand Mobile Network, public land mobile network) list; the network operators to which the first identity recognition module and the second identity recognition module belong belong to the equivalent Home PLMN (Home Public Land Mobile Network, belonging to the public land mobile network ) list, operators in these lists have signed a mutual authorization agreement, and users belonging to an operator in this list can register with any PLMN in this list.

Step S102: Establish a network connection for the second identity recognition module according to network-related information.

It can be seen from the above introduction that the predetermined process includes but is not limited to any of the following situations: network registration, inter-system redirection, system switching, etc., wherein the system switching includes intra-system switching and/or inter-system switching.

The embodiment of the present invention also provides a network connection method, which is suitable for when the first identity recognition module and the second identity recognition module try to register in different radio access technologies RAT, the specific steps of the network connection method include:

Executing a predetermined reading method for the non-essential system information corresponding to the registration network of the second identity recognition module, and establishing a network connection for the second identity recognition module.

Optionally, register the second identity recognition module with the GSM network.

Optionally, when the second identity recognition module only supports circuit switched CS domain services, the non-essential system information includes: GSM system message 13 .

Specifically, the predetermined reading mode is delayed reading or no reading. In this embodiment of the invention, the types of identity recognition modules include physical identity recognition cards and virtual subscriber identity modules. Card (User Identity Module, Subscriber Identification Module), PIM Card (Personal Information Management System, Personal Information Manager), USIM Card (Universal Subscriber Identity Module, Global Subscriber Identity Card), RUIM Card (Removable User Identity Module, removable user identification module) and so on. The virtual user identity module is relative to the physical identity card. There is no physical hardware card slot and physical identity card on the user device, and the user's identity information is stored in the storage area of the user device (it can be built-in RAM or external memory card). The user terminal can be a mobile phone, a tablet computer, a wearable smart device, and other devices that have the function of setting an identity recognition module.

The network connection method provided by the embodiment of the present invention. Applied to multi-card multi-standby application terminals, including multi-card multi-standby single-pass application terminals and multi-card multi-standby multi-communication application terminals.

In the network connection method provided by the embodiment of the present invention, when it is detected that the predetermined process for the second identity recognition module starts, the network-related information of the first identity recognition module that can be reused by the second identity recognition module is obtained; according to the network-related information, Establish a network connection for the second identity recognition module; in the present invention, directly share network-related information through the first identity recognition module, so that the second identity recognition module does not need to perform steps such as network search process, inter-system measurement or intra-system measurement. It can complete the network connection, speed up the network connection process, effectively save time delay and improve user experience.

A number of embodiments of the technical solution of the present invention will be specifically introduced below by taking a dual identity card as an example.

Embodiment one

Embodiment 1 of the present invention introduces the time delay optimization when the user terminal performs a network registration process after it is turned on.

Taking registration to the GSM (Global System for Mobile Communication, Global System for Mobile Communication) network as an example for illustration, as shown in Figure 2, after the terminal is powered on, the existing identification card needs to complete the steps shown in step S201 through the protocol stack. Process: scan the GSM frequency point to find the cell with the best signal; synchronize the FCCH (Frequency Correction Channel)/SCH (Synchronization Channel) channel of the cell; read the necessary system information for registering the GSM network.

Then carry out the registration process, the process shown in step S202 in Figure 2: set up RRC (Radio Resource Control, radio resource control) connection; Initiate LAU (Location Area Updating, location area update) process (if NMO (Network Mode of Operation, network The working mode) is 2); initiate a GPRS (General Packet Radio Service, General Packet Radio Service) attach process, that is, the ATTACH process; release the RRC connection.

The inventors of the present invention have found through research that, for the application scenario of a dual-card dual-standby user terminal, if the inserted first identification card and the second identification card belong to the same operator or the operator to which the two identification cards belong belongs to The same equivalent PLMN (Public Land Mobile Network, public land mobile network) list or equivalent Home PLMN (Home Public Land Mobile Network, belonging to the public land mobile network) list, the operators in this list have signed a mutual authorization agreement, A user belonging to a certain operator in this list can register in any PLMN in the list, that is, the first identity card and the second identity card try to register in the same RAT (Radio Access Technology, wireless access technology) or when the second ID card tries to register with a cell adjacent to the cell where the first ID card is currently located, or when the second ID card tries to register with the cell measured by the first ID card for signal measurement In this case, after the first ID card completes the registration process, the second ID card can directly execute the step shown in step S203 in FIG. The step of obtaining the necessary system information to register the GSM network, directly obtain the cell information of the cell where the first ID card is currently located, so as to directly register to the cell where the first ID card is currently located, or directly obtain the cell information where the first ID card is currently located The cell information of the adjacent cell of the cell, so as to directly register with the adjacent cell of the cell where the first identity card is currently located.

In actual use, the specific judgment methods for trying to register in the same RAT include any of the following:

The first one is to judge according to the network type environment: for example, when the terminal is turned on to search the network, the network environment where there is only a GSM network, it can be directly judged that the first ID card and the second ID card are trying to register in the same RAT;

The second is to judge according to the network type supported by the terminal: for example, the terminal can only support the GSM network in the terminal, then it can be directly judged that the first ID card and the second ID card try to register in the same RAT;

It can be understood that, before the network registration for the second identity recognition card is started, the network registration for the first identity recognition card is executed first after the user terminal is turned on.

In Embodiment 1 of the present invention, for the second identification card, the only process that needs to be performed is: judging whether the network operators to which the first identification card and the second identification card belong are in the same equivalent PLMN list or etc. The Home PLMN list of the price, and whether the first ID card and the second ID card try to register the same RAT; if both are judged to be yes, the cell information of the cell where the first ID card is currently located is obtained, that is, the measurement is skipped 1. In the process of selecting a target cell, reading system information, etc., the cell where the first identity card is currently located is directly used as the target cell. Then, a channel synchronization process is performed to synchronize the FCCH/SCH channels of the cell. Then, according to the cell information of the obtained first ID card currently located in the cell, perform network registration for the second ID card, that is, the steps shown in step S204 in Figure 2: set up an RRC connection; initiate the LAU process (if NMO Yes 2); initiate the ATTACH process; release the RRC connection.

Optionally, the second identity card can also obtain the cell information of the cell where the first identity card is currently located or the cell that is measured when the first identity module performs signal measurement, that is, the measurement is skipped and the target is selected. The processes such as the cell directly take the adjacent cell of the cell where the first identity card is currently located as the target cell. If the second ID card selects the adjacent cell to initiate network registration and reads the necessary system information, the second ID card can reuse the frequency point and signal strength information of the adjacent cell where the first ID card is currently located .

Similarly, in addition to the GSM network, registration to other networks can also use the above method of sharing cell information to optimize the delay, as long as the network operators to which the first ID card and the second ID card belong are in the same equivalent PLMN list or the equivalent Home PLMN list, and the first ID card and the second ID card try to register the same RAT, the cell where the first ID card is currently located can be used as the target cell, and the current cell where the first ID card is located can be shared The cell information of the cell directly executes the network registration for the second identity card.

The above delay optimization method for the network registration process directly shares the cell information of the current cell through the first ID card after registration, so that the second ID card does not need to measure, select the target cell, and read system information. The network registration can be completed, the network registration process can be accelerated, the delay can be effectively saved, and the user experience can be improved.

After completing the registration, the first ID card directly shares the cell information of the adjacent cell of the current cell, so that the second ID card can complete the network registration without steps such as measuring and selecting the target cell, speeding up the network registration process, and effectively Save time delay and improve user experience.

Embodiment two

The second embodiment of the present invention introduces the delay optimization during network redirection.

In the example scenario, the second identity card has already resided in the LTE (Long Term Evolution, long-term evolution technology) network. The identity card sends an ESR (Extended Service Request, Extended Service Request) message to the LTE network to trigger a CSFB (Circuit Switched Fall Back, Circuit Switched Fall Back) process. Then receive the RRC connection release message sent by the LTE network, wherein the RRC connection release message carries the CSFB's network standard and frequency point list for the target cell of the second identity card.

In this scenario, the existing identity card also needs to complete the same process as that shown in step S201 in FIG. 2 above. However, in Embodiment 2 of the present invention, as shown in FIG. 3 , after receiving the RRC connection release message for the second ID card, it is considered that the start of network redirection for the second ID card is detected. First, it can be judged that the network operator to which the second identity card belongs is the same operator as the network operator to which the first identity card belongs, or is in the same equivalent PLMN list or the equivalent Home PLMN list, and the first identity identification card Whether the frequency point of the cell where the card is currently located is included in the frequency list of the target cell of the second identity card carried in the RRC connection release message. If so, the second identity card is directly camped in the cell where the first identity card is currently located to complete the subsequent call establishment process.

Preferably, after receiving the RRC connection release message for the second identity card (the RRC connection release message may carry the frequency point list of the target cell of the second identity card), the first identity card can be directly judged. Whether the frequency point of the cell where the card is currently located exists in the frequency point list of the target cell of the second ID card; The target cell, system information reading and other processes directly use the cell where the first identity card is currently located as the target cell. Then, carry out the channel synchronization process and initiate the LAU process (if necessary), according to the obtained cell information of the cell where the first ID card is currently located, perform network redirection for the second ID card, so that the second ID card Redirect to 2G network to establish flow for continued outgoing or incoming calls.

Optionally, it is determined whether the adjacent cell of the cell where the first identity identification card is currently located, or the frequency point of the cell measured when the first identity identification module performs signal measurement exists in the frequency point list of the target cell of the second identity identification card If the judgment is yes, the cell information of the adjacent cell of the cell where the first ID card is currently located is obtained, that is, the process of measuring and selecting the target cell is skipped, and the adjacent cell of the cell where the first ID card is currently located is directly used. The cell is the target cell. If the second ID card is redirected to the adjacent cell, the necessary system information will also be read, but the second ID card can reuse the frequency point and signal strength information of the adjacent cell of the cell where the first ID card is currently located .

Similarly, except for the scenario where the first ID card resides in the 2G network and the second ID card is redirected from the LTE network, for other inter-network redirection scenarios, the above-mentioned way of sharing cell information can be used to optimize delay. As long as the second identity card receives the RRC connection release message sent by the network side, it does not measure the frequency points in the frequency point list of the target cell carried in the message, but first judges the frequency point to which the second identity card belongs. The network operator and the network operator to which the first identity card belongs are the same operator or are in the same equivalent PLMN list or equivalent Home PLMN list, and the frequency point of the cell where the first identity card is currently located, the first Whether the frequency point of the adjacent cell of the cell where the ID card is currently located, or the cell measured by the first identity recognition module during signal measurement is in the frequency point list of the target cell, if it happens to be in the frequency point list of the target cell, then Directly reuse the information of the cell where the first identity card is currently located, the adjacent cell of the current cell, or the cell measured during signal measurement, and skip the steps of target cell measurement and target cell selection to complete the redirection process. This greatly saves the delay in the redirection process, speeds up the call establishment process, and improves user experience.

Embodiment three

Embodiment 3 of the present invention introduces delay optimization during system handover, wherein the system handover includes intra-system handover and/or inter-system handover.

The third embodiment of the present invention is used as an example scenario, where the signal quality of the LTE network where the second ID card is located deteriorates rapidly, and system switching is to be triggered, and occurs after receiving a measurement control message for the second ID card sent by the LTE network of.

In other words, in this scenario, the detection of the initiation of system switching for the second identity recognition card means that when the signal strength of the network where the second identity recognition card is located is lower than a predetermined threshold, the measurement control for the second identity recognition card is received. after the news.

The measurement control message carries the neighbor cell list of the second identity card.

In this scenario, the existing identification card needs to perform intra-system or inter-system measurement, and send the measurement results of each cell in the neighbor cell list to the network side for cell selection. However, in Embodiment 3 of the present invention, after the second ID card receives the measurement control message issued by the LTE network, it first determines whether the cell where the first ID card is currently located and/or the adjacent cells of the cell where the first ID card is currently located is included. In the neighbor cell list carried in the measurement control message, instead of performing the measurement first. If the cell where the first ID card is currently located and/or the neighboring cells of the current cell is just in the neighbor list, then obtain the signal quality measurement of the cell where the first ID card is currently located and/or the neighboring cells of the current cell As a result, it is directly used for reporting the measurement report of the second identity card.

Specifically, when the signal quality measurement result satisfies the measurement report criterion, the signal quality measurement result of the cell where the first identity card is currently located and/or the adjacent cell of the current cell is sent to the network as a measurement report of the second identity card side.

Wherein, the measurement report criterion is also determined in the measurement control message, and the terminal can report the signal quality measurement result according to the measurement report criterion.

Then, a handover command issued by the network side can be received, and the handover command includes the information that the cell where the first ID card is currently located or the adjacent cell where the cell is currently located is used as the target cell of the second ID card; according to the Handover command, switch the second identity card to the cell where the first identity card is currently located or an adjacent cell of the current cell. Figure 4 shows a schematic flow diagram taking the cell where the first identity card is currently located as an example. It saves the delay caused by reporting multiple measurement reports, and accelerates the decision-making process on the network side, so that intra-system handover or inter-system handover can be quickly triggered, reducing the risk of call drop in fast-moving scenarios.

Similarly, except for the above-mentioned scenario where the second identity card resides in the LTE network, for other system handover scenarios, as long as the cell where the first identity card is currently located and/or the adjacent cell of the current cell is included in the second identity card In the neighboring cell list of the identification card, by sharing the network-related information of the first identification card, the second identification card can be directly handed over to the cell where the first identification card is currently located or a neighboring cell of the current cell. For example, the second identity card may only send the signal quality measurement results of the cell where the first identity card is currently located and/or the neighboring cells of the current cell to the network side, instead of sending the measurement results of neighboring cells in the neighboring cell list. The results are all sent to the network side, so as to quickly trigger intra-system handover or inter-system handover, and directly switch the second ID card to the cell where the first ID card is currently located or a neighboring cell of the current cell. In this way, in a fast-moving scene, call drops caused by untimely reporting of measurement reports can be avoided, thereby improving user experience.

Optionally, the cell measured when the first identity recognition module performs signal measurement can also be used to perform corresponding intra-system handover or inter-system handover. Same, no more details here.

Embodiment four

Embodiment 4 of the present invention introduces another kind of time delay optimization when the user terminal performs a network registration process after it is turned on.

If the first ID card and the second ID card try to register under different RATs, take the first ID card trying to register on the LTE network and the second ID card trying to register on the GSM network as an example, after the terminal is turned on , as shown in Figure 5, the first identity card needs to complete the following process through the protocol stack: Step S501: Scan the LTE frequency point and find out the LTE cell with the best signal; perform PSS (Primary Synchronization Signal, primary synchronization signal)/SSS (Secondary Synchronization Signal, auxiliary synchronization signal) detection and wireless frame synchronization, time synchronization and frequency synchronization; read the main information block (MIB) and necessary system information blocks (SIBs), and then complete step S502: establish RRC connection; initiate ATTACH Process; ATTACH is completed; the process of releasing the RRC connection and other registered networks.

Then, if the first ID card and the second ID card try to register with different RATs, it is considered that the network-related information of the first ID card does not meet the conditions for establishing a network connection for the second ID card. Embodiment 1 Different delay optimization manners.

In Embodiment 4 of the present invention, the network connection for the second identity recognition card can be established by reading the system information used by the second identity recognition card to register the network. That is to say, only the necessary system information is read when the second identity card is used to register the network, and the non-essential system information corresponding to the registered network is delayed or not read, thereby saving the registration delay of the second identity card .

As an example, when the second identity card only supports CS (Circuit Switched, Circuit Switched) domain services, then in the registration process, as shown in step S503, the second identity card can delay reading or not read those Unnecessary system information for CS domain services, such as system message 13, etc., thereby saving the registration delay of the second identification card, the specific steps include: searching for GSM frequency points and finding the best cell; synchronizing FCCH/SCH Channel: read necessary GSM messages, if the second identity card only works in the CS domain, delay reading system information 13.

Then execute the registration process shown in step 504: establish the RRC connection; initiate the LAU process; release the RRC connection.

The above delay optimization method for the network registration process reads the necessary system information when the second identity card is used to register the network, and delays or does not read the non-essential system information corresponding to the registration network, thereby saving the second The registration delay of the identification card improves the user experience.
