Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

In consideration of the fact that the user experience is seriously influenced by the delay phenomenon existing in the network connection process, embodiments of the present invention provide a network connection method, an apparatus and a user terminal, which accelerate the network connection process and effectively save the time delay, and are described below by embodiments.

An embodiment of the present invention provides a network connection method, where a flow diagram of the method is shown in fig. 1, and the method specifically includes:

step S101: when detecting that a preset process aiming at a second identity recognition module is started, acquiring network related information of a first identity recognition module which can be reused by the second identity recognition module;

specifically, network related information of a cell corresponding to a first identity module reusable by a second identity module is obtained. Wherein the respective cell comprises any one of: a first identity recognition module is located in a current cell; a cell adjacent to a cell in which the first identity recognition module is currently located; and the first identity identification module carries out the measured cell during signal measurement.

That is, when it is detected that a predetermined procedure for the second identity module is started, network-related information of a cell in which the first identity module that can be reused by the second identity module is currently located may be acquired; network related information of a cell adjacent to a cell where the first identity recognition module which can be reused by the second identity recognition module is located at present can also be obtained; or network related information of the cell measured when the first identity module reused by the second identity module performs signal measurement can be obtained.

In practical applications, the processing modes of the cell measured by the first identity module when performing signal measurement are the same as the processing modes of the neighboring cell of the cell where the first identity module is currently located, which is described below by taking the neighboring cell of the cell where the first identity module is currently located as an example, and the details of the situation of the cell measured by the first identity module when performing signal measurement are not repeated.

The network related information comprises at least one of cell information, a signal quality measurement result, frequency point information and signal strength information, and the cell information mainly comprises contents such as frequency points where cells are located, public channel parameters, system broadcast messages and the like.

In practical applications, the determining the first identity module reusable by the second identity module specifically includes:

the first identity recognition module which can be reused by the second identity recognition module is determined from other identity recognition modules based on the network state of the network to which the other identity recognition modules except the second identity recognition module belong.

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

The multi-card multi-standby user terminal may include a plurality of identity modules, and when it is detected that a predetermined procedure for the second identity module is started, for example, the second identity module pre-executes cell search to perform network registration, or the second identity module pre-executes cell frequency scanning to perform network redirection, or the second identity module pre-executes inter-system or intra-system measurement to perform system handover, etc., it is conceivable that, at this time, other identity modules in the terminal except the second identity module may include a plurality of states in which the second identity module can reuse network related information:

the first method comprises the following steps: only one identity module is registered, for example, the first identity module, and the network related information of the cell where the first identity module is currently located or the neighboring cell of the cell where the first identity module is currently located can be directly reused by the second identity module, and at this time, only the network related information of the cell where the first identity module is currently located or the neighboring cell of the cell where the first identity module is currently located needs to be directly acquired for establishing network connection.

And the second method comprises the following steps: at least two identity modules are registered, such as a first identity module and a third identity module, wherein only the network related information of the cell where the first identity module is currently located or the adjacent cell of the cell where the first identity module is currently located can be directly reused by the second identity module, and the network related information of other identity modules such as the third identity module and the like currently located or the adjacent cell of the cell where the first identity module is currently located cannot be directly reused by the second identity module, so that the network related information of the cell where the first identity module is currently located or the adjacent cell of the cell where the first identity module is currently located only needs to be directly acquired for establishing network connection.

Thirdly, at least two identity recognition modules are registered, network related information of a current cell of the at least two identity recognition modules or a cell adjacent to the current cell can be acquired by the second identity recognition module, and at this time, the at least two identity recognition modules need to be selected, for example, when the cells in which the two registered identity recognition modules are located are the same, the identity recognition module with the largest cell signal intensity can be selected; or selecting the identity recognition module with the highest cell signal receiving quality; or a plurality of conditions may be combined to perform comprehensive judgment, which is not limited herein. Taking the first identity module as an example, the network related information of the cell where the first identity module is currently located or the neighboring cell of the cell where the first identity module is currently located is obtained for establishing the network connection. When the two registered identity modules are located in different cells, the second identity module may arbitrarily select one identity module to obtain network related information of the current cell or a cell adjacent to the current cell for establishing network connection.

It should be noted that, the network related information of the cell where the first identity module is currently located or the neighboring cell of the cell where the first identity module is currently located may be reused by the second identity module, first, the second identity module tries to register the RAT to which the serving cell where the first identity module is currently located belongs, or the RAT to which the neighboring cell of the cell where the first identity module is currently located belongs, or the RAT to which the cell measured when the first identity module performs signal measurement belongs, and a network operator to which the first identity module and the second identity module belong needs to meet a predetermined condition. If the RAT to which the serving cell where the first identity module is currently located belongs is the same as the RAT to which the serving cell where the second identity module attempts to register belongs, it may be determined that the first identity module and the second identity module attempt to register in the same RAT. The predetermined conditions that the network operator needs to meet include any of the following: 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 module and the second identity module belong are in the same equivalent PLMN (Public Land Mobile Network) list; the Network operators to which the first identity module and the second identity module belong to an equivalent Home PLMN (Home Public Land Mobile Network) list, the operators in the lists sign mutual authorization agreements, and a user belonging to a certain operator in the list can register any PLMN in the list.

Step S102: and establishing network connection aiming at the second identity identification module according to the network related information.

From the above description, the predetermined flow includes, but is not limited to, any of the following situations: network registration, inter-system redirection, system handover and the like, wherein the system handover comprises intra-system handover and/or inter-system handover.

The embodiment of the invention also provides a network connection method, which is suitable for the first identity module and the second identity module to try to register in different Radio Access Technologies (RAT), and comprises the following specific steps:

Optionally, the second identity module is registered to the GSM network.

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

Specifically, the predetermined reading manner is delayed reading or non-reading. In the embodiment of the present invention, the types of the Identity Module include an entity Identity Module (SIM) and a virtual Subscriber Identity Module (SIM), and specifically, the entity Identity Module (SIM) at least includes a Subscriber Identity Module (SIM), a User Identity Module (UIM), a Personal Information Management (PIM) card, a Universal Subscriber Identity Module (USIM), a Universal Subscriber Identity Module (RUIM), and the like. The virtual user identity module is that, compared with an entity identity card, the user equipment does not have an entity hardware card slot and an entity identity card, and the identity information of the user is stored in a storage area (which may be an internal RAM or an external memory card) of the user equipment. The user terminal can be a mobile phone, a tablet computer, a wearable intelligent device and other devices with the function of setting the identity recognition module.

The embodiment of the invention provides a network connection method. The method is applied to the multi-card multi-standby application terminal and comprises the multi-card multi-standby single-pass application terminal and the multi-card multi-standby multi-pass application terminal.

According to the network connection method provided by the embodiment of the invention, when the preset process aiming at the second identity identification module is detected to be started, the network related information of the first identity identification module which can be reused by the second identity identification module is obtained; establishing network connection aiming at the second identity recognition module according to the network related information; in the invention, the first identity recognition module directly shares the related information of the network, so that the second identity recognition module can complete the network connection without executing the steps of network searching process, inter-system measurement or intra-system measurement and the like, thereby accelerating the network connection process, effectively saving time delay and improving user experience.

A plurality of embodiments of the technical solution of the present invention are specifically described below by taking a dual identification card as an example.

Example one

In the first embodiment of the present invention, delay optimization during a network registration process is performed after a user terminal is powered on.

Taking registration in a GSM (Global System for Mobile Communication) network as an example for explanation, as shown in fig. 2, after the terminal is powered on, the existing identification card needs to complete the process shown in step S201 through the protocol stack: scanning GSM frequency points to find out a cell with the best signal; synchronizing the FCCH (Frequency Correction Channel)/SCH (Synchronization Channel) Channel of the cell; the system messages necessary to register with the GSM network are read.

Then, a registration process is performed, as shown in step S202 in fig. 2: establishing RRC (Radio Resource Control) connection; initiate a LAU (Location Area update) procedure (if NMO (Network Mode of Operation) is 2); initiating a General Packet Radio Service (GPRS) ATTACH procedure, i.e., ATTACH procedure; the RRC connection is released.

The inventor of the present invention has found, through research, that for an application scenario of a dual-card dual-standby user terminal, if the inserted first identity card and the inserted second identity card belong to the same operator or the operators to which the two identity cards belong to the same equivalent PLMN (Public Land Mobile Network) list or the equivalent Home PLMN (Home Public Land Mobile Network) list, the operators in the list sign mutual authorization protocols, and a user belonging to one operator in the list can register to any PLMN in the list, that is, when the first identity card and the second identity card attempt to register to the same RAT (Radio Access Technology), or, when the second identification card tries to register to a cell adjacent to the cell where the first identification card is currently located, or when the second identification card tries to register to a cell measured when the first identification card performs signal measurement, after the first identification card completes the registration process, the second identification card may directly perform the step shown in step S203 in fig. 2, that is, the step of scanning GSM frequency points to find a cell with the best signal and reading system messages necessary for registering a GSM Network is skipped, and cell information of the cell where the first identification card is currently located is directly obtained so as to directly register to the cell where the first identification card is currently located, or cell information of a cell adjacent to the cell where the first identification card is currently located is directly obtained so as to directly register to a cell adjacent to the cell where the first identification card is currently located.

In practical use, the specific judgment way of attempting to register in the same RAT includes any one of the following:

the first method comprises the following steps of judging according to the network type environment: for example, if the terminal only has a GSM network in the network environment when the terminal is turned on to search for a network, it may be directly determined that the first identification card and the second identification card attempt to register in the same RAT;

and secondly, judging according to the network types supported by the terminal: for example, if the terminal can only support a GSM network at the terminal, it may be directly determined that the first id card and the second id card attempt to register in the same RAT;

it is understood that the network registration for the first identification card is performed after the user terminal is powered on before the network registration for the second identification card is started.

In the first embodiment of the present invention, for the second identification card, the process that only needs to be executed is: judging whether network operators to which the first identity identification card and the second identity identification card belong are in the same equivalent PLMN list or the equivalent Home PLMN list, and whether the first identity identification card and the second identity identification card try to register the same RAT; if the judgment result is yes, the cell information of the cell where the first identity card is currently located is obtained, namely, the processes of measurement, target cell selection, system information reading and the like are skipped, and the cell where the first identity card is currently located is directly used as the target cell. Then, a channel synchronization procedure is performed to synchronize the FCCH/SCH channel of the cell. Then, according to the acquired cell information of the cell in which the first identification card is currently located, network registration for the second identification card is executed, that is, as shown in step S204 in fig. 2, the steps are as follows: establishing RRC connection; initiate LAU procedure (if NMO is 2); initiating an ATTACH process; the RRC connection is released.

Optionally, the second identity card may also obtain cell information of a cell adjacent to the cell measured by the first identity card when the cell is currently located or the first identity module performs signal measurement, that is, the processes of measurement, target cell selection and the like are skipped, and the cell adjacent to the cell where the first identity card is currently located is directly used as the target cell. If the second identification card selects the adjacent cell to initiate network registration, necessary system information needs to be read, and the frequency point and signal strength information of the adjacent cell of the cell where the first identification card is currently located can be reused by the second identification card.

Similarly, in addition to the GSM network, the above-mentioned method of sharing cell information may be used to optimize the time delay when registering in other networks, so long as the network operators to which the first identity card and the second identity card belong are in the same equivalent PLMN list or equivalent Home PLMN list, and the first identity card and the second identity card attempt to register in the same RAT, the cell in which the first identity card is currently located may be the target cell, and network registration for the second identity card may be directly performed by sharing the cell information of the cell in which the first identity card is currently located.

In the time delay optimization mode for the network registration process, the registered first identity identification card directly shares the cell information of the current cell, so that the second identity identification card can complete the network registration without measuring, selecting the target cell, reading the system information and other steps, the network registration process is accelerated, the time delay is effectively saved, and the user experience is improved.

The registered first identity recognition card directly shares the cell information of the adjacent cell of the current cell, so that the second identity recognition card can complete network registration without measuring, selecting a target cell and other steps, the network registration process is accelerated, time delay is effectively saved, and user experience is improved.

Example two

In the second embodiment of the invention, time delay optimization during network redirection is described.

In an exemplary scenario, the second identity card already resides in an LTE (Long Term Evolution) network, and when there is an outgoing call or an incoming call for a telephone of the second identity card, an ESR (Extended Service Request) message needs to be sent to the LTE network for the second identity card to trigger a CSFB (Circuit Switched Fall Back) procedure. And then, receiving an RRC connection release message sent by the LTE network, wherein the RRC connection release message carries the network type and the frequency point list of the CSFB for the target cell of the second identity recognition card.

The existing id card in this scenario also needs to complete the same process as shown in step S201 in fig. 2. In the second embodiment of the present invention, as shown in fig. 3, after receiving the RRC connection release message for the second identification card, it is regarded as that the network redirection for the second identification card is initiated. Firstly, it can be judged whether the network operator to which the second identification card belongs and the network operator to which the first identification card belongs are the same operator or in the same equivalent PLMN list or equivalent Home PLMN list, and whether the frequency point of the cell in which the first identification card is currently located is included in the frequency list of the target cell of the second identification card carried in the RRC connection release message. If yes, directly residing the second identity recognition card in the cell where the first identity recognition card is currently located to complete the subsequent call establishment process.

Preferably, after receiving an RRC connection release message for the second identity card (the RRC connection release message may carry a frequency point list of a target cell of the second identity card), the method may directly determine whether a frequency point of a cell where the first identity card is currently located exists in the frequency point list of the target cell of the second identity card; if the first identity card is judged to be the target cell, the cell information of the cell where the first identity card is currently located is obtained, namely, the processes of measurement, target cell selection, system information reading and the like are skipped, and the cell where the first identity card is currently located is directly used as the target cell. And then, performing a channel synchronization process and an LAU initiating process (if needed), and executing network redirection aiming at the second identity card according to the acquired cell information of the cell where the first identity card is currently located so as to redirect the second identity card to a 2G network to establish a flow for continuing the outgoing call or the incoming call.

Optionally, judging whether the frequency point of the cell measured when the first identity card is currently located in the adjacent cell of the cell or the first identity module measures the signal exists in the frequency point list of the target cell of the second identity card; if the first identity card is judged to be the target cell, the cell information of the adjacent cell of the cell where the first identity card is currently located is obtained, namely, the processes of measurement, target cell selection and the like are skipped, and the adjacent cell of the cell where the first identity card is currently located is directly taken as the target cell. If the second identification card is redirected to the adjacent cell, necessary system information is read, but the second identification card can reuse the frequency point and signal strength information of the adjacent cell of the cell where the first identification card is currently located.

Similarly, except for the scenario that the first identity card resides in the 2G network and the second identity card redirects from the LTE network, the time delay may be optimized in the manner of sharing the cell information for redirection between other networks. When the second identity card receives the RRC connection release receipt message sent by the network side, the frequency point in the frequency point list of the target cell carried in the message is not measured, but the network operator to which the second identity card belongs and the network operator to which the first identity card belongs are judged to be the same operator or in the same equivalent PLMN list or equivalent Home PLMN list, the frequency point of the cell in which the first identity card is currently located, the frequency point of the cell adjacent to the cell in which the first identity card is currently located, or whether the cell measured by the first identity module during signal measurement is in the frequency point list of the target cell, if the cell is just in the frequency point list of the target cell, the cell in which the first identity card is currently located, the cell adjacent to the cell in which the first identity card is currently located, or the information of the cell measured during signal measurement is directly reused, the steps of target cell measurement, target cell decision and the like are skipped, so that the redirection process can be completed, the time delay of the call establishment process is greatly saved, and the redirection experience of the user is improved.

EXAMPLE III

In a third aspect of the embodiments of the present invention, a delay optimization during system handover is described, where the system handover includes intra-system handover and/or inter-system handover.

The third scenario of the embodiment of the present invention is that when the LTE network signal quality where the second identification card is located deteriorates rapidly and system handover is to be triggered, the scenario occurs after a measurement control message for the second identification card sent by the LTE network is received.

In other words, in this scenario, the detection of the initiation of the system switch for the second identification card is after the reception of the measurement control message for the second identification card when the signal strength of the network on which the second identification card is located is lower than the predetermined threshold.

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

In the scene, the existing identity card needs to perform intra-system measurement or inter-system measurement, and the measurement results of each cell in the neighbor cell list are all sent to the network side to perform cell selection. In the third embodiment of the present invention, after the second identity card receives the measurement control message sent by the LTE network, it is first determined whether the cell where the first identity card is currently located and/or the neighboring cell of the cell where the first identity card is currently located are included in the neighboring cell list carried in the measurement control message, instead of performing the measurement first. And if the current cell of the first identity card and/or the adjacent cell of the current cell are/is just in the adjacent cell list, acquiring the signal quality measurement result of the current cell of the first identity card and/or the adjacent cell of the current cell, and directly reporting the measurement report of the second identity card.

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

The measurement report criteria are also determined in the measurement control message, and the terminal can report the signal quality measurement result according to the measurement report criteria.

Then, a switching command issued by a network side can be received, wherein the switching command comprises information of a current cell of the first identity card or a cell adjacent to the current cell as a target cell of the second identity card; according to the switching command, the second identity card is switched to the current cell of the first identity card or the adjacent cell of the current cell, and fig. 4 shows a schematic flow chart taking the current cell of the first identity card as an example, so that time delay caused by reporting multiple measurement reports can be saved, and the decision process at the network side is accelerated, thereby rapidly triggering intra-system switching or inter-system switching, and reducing the risk of call drop in a fast moving scene.

Similarly, in addition to the scenario that the second identity card resides in the LTE network, for other system handover scenarios, as long as the current cell of the first identity card and/or the neighboring cell of the current cell are included in the neighboring cell list of the second identity card, the second identity card may be directly handed over to the current cell of the first identity card or the neighboring cell of the current cell by sharing the network related information of the first identity card. For example, the second identity card may only send the signal quality measurement result of the cell where the first identity card is currently located and/or the signal quality measurement result of the neighboring cell of the cell where the first identity card is currently located to the network side, and not send the measurement results of the neighboring cells in the neighboring cell list to the network side any more, so as to quickly trigger intra-system handover or inter-system handover, and directly switch the second identity card to the cell where the first identity card is currently located or the neighboring cell of the cell where the second identity card is currently located. Therefore, under the scene of rapid movement, the call drop caused by untimely reporting of the measurement report can be avoided, and the user experience is improved.

Optionally, the cell measured by the first identity module during signal measurement may also be used to perform corresponding intra-system handover or inter-system handover, and the process is the same as the processing method of the neighboring cell of the cell where the first identity module is currently located, which is not described herein again.

Example four

In the fourth embodiment of the present invention, another time delay optimization during the network registration process is performed after the user terminal is powered on.

If the first id card attempts to register in the LTE network and the second id card attempts to register in the GSM network when the first id card and the second id card attempt to register in different RATs, as shown in fig. 5, after the terminal is powered on, the first id card needs to complete the following processes through a protocol stack: step S501: scanning LTE frequency points and finding out an LTE cell with the best signal; performing PSS (Primary Synchronization Signal)/SSS (Secondary Synchronization Signal) detection and wireless frame, time, and frequency Synchronization; reads the Master Information Block (MIB) and necessary System Information Blocks (SIBs), and then completes step S502: establishing RRC connection; initiating an ATTACH process; ATTACH is completed; procedure for releasing RRC connection and the like to register the network.

Then, the first identity card and the second identity card attempt to register different RATs, and it is determined that the network related information of the first identity card does not satisfy the condition of establishing network connection for the second identity card, at this time, a different delay optimization manner from that in the first embodiment is adopted.

In the fourth embodiment of the present invention, a network connection for the second identification card may be established by reading the system information of the second identification card used for registering the network. That is, only the necessary system information of the second identification card for registering the network is read, and the reading or non-necessary system information corresponding to the registered network is delayed, so that the registration delay of the second identification card is saved.

For example, when the second identification card only supports CS (Circuit Switched) domain services, then in the registration process, as shown in step S503, the second identification card may delay reading or not reading system information that is unnecessary for CS domain services, such as system message 13, so as to save the registration delay of the second identification card, and the specific steps include: searching GSM frequency points and finding out the best cell; synchronizing the FCCH/SCH channels; reading the necessary GSM messages delays reading the system information 13 if the second identification card is only operating in the CS domain.

The registration process is then performed as shown in step 504: establishing RRC connection; initiating a LAU procedure; the RRC connection is released.

In the time delay optimization mode aiming at the network registration process, the necessary system information when the second identity card is used for registering the network is read, and the unnecessary system information corresponding to the registered network is delayed to be read or not to be read, so that the registration time delay of the second identity card is saved, and the user experience is improved.

Optionally, the predetermined procedure is inter-system redirection, and the information obtaining module 601 is specifically configured to receive a connection release message RRC for the second identity card, where the RRC connection release message carries a frequency point list of a target cell of the second identity card.

Based on this, the information obtaining module 601 is further specifically configured to determine whether the frequency point of the cell where the first identity card is currently located exists in the frequency point list of the target cell of the second identity card; and if so, acquiring cell information of a cell corresponding to the first identity card.

At this time, the network connection establishing module 602 is further specifically configured to send the signal quality measurement result of the cell where the first identity card is currently located to the network as the measurement report of the second identity card when the signal quality measurement result meets the measurement report criterion.
