Description

Dual-card network searching configuration method and device and computer readable storage medium

Technical Field

The present invention relates to the field of mobile communications, and in particular, to a method and an apparatus for configuring a dual-card network search, and a computer-readable storage medium.

Background

In the prior art, a network searching mechanism after starting up and a re-searching mechanism after losing a network are mature, and the general idea is to reduce the power consumption of network searching and balance fast network staying as much as possible.

On one hand, consider that there are multiple search states for a terminal: firstly, searching a network frequency band which once resides before network loss; secondly, searching different frequency bands of different systems supported by the current card operator; and thirdly, entering an emergency network searching state, and searching different frequency bands of different systems of other operators so as to obtain emergency service support. Meanwhile, in order to save power consumption, a power save dormant state exists in the network searching process, the terminal is dormant most of the time during the period, and the network searching is performed at different times or not at all according to different algorithms.

On the other hand, considering that terminals such as mobile phones in the market basically support double cards, the existing double-card network searching mechanism is that each card independently and parallelly executes the network searching logic without interference. That is, the network searching command is sent to the NAS (Non-Access Stratum) module, and a final network searching behavior requires using a radio frequency device on the bottom layer, and since the terminals of DSDS (Dual SIM Dual standby) or DSDA (Dual SIM Dual active) all have scheduling and allocation of RF resources, when a network searching logic of a certain card triggers network searching, it is very likely that the RF resources are occupied by another card, and it is necessary to wait for the resources to be released before obtaining the RF resources.

In summary, the network searching mechanisms of the dual cards are independent and mutually influenced, and different operator cards and different network mode settings all cause the network searching states of the dual cards to be irrelevant, i.e. when one card searches for a network, another card may wait for radio frequency resources to search for a network and also may sleep in power save, one card may search for a plurality of frequency point lists, and the other card may search for a network in a full frequency band. Therefore, how to save the power consumption of searching the network and increase the speed of searching the network in the process becomes a technical problem to be solved urgently at present.

Based on the hardware structure of the mobile terminal, the invention provides various embodiments of the method.

Fig. 2 is a flowchart of a dual-card network searching configuration method according to a first embodiment of the present invention. The embodiment provides a network searching configuration method for double cards, which comprises the following steps:

s1, when a second non-access layer corresponding to a second card of a terminal receives a SERVICE _ REG _ CNF1 first network searching failure message of a first card of the terminal at a first radio resource control layer, detecting whether the second non-access layer has a PLMN _ REG _ REQ2 second network searching request to be executed;

s2, when the PLMN _ REG _ REQ2 does not exist in the second non-access layer, ending network searching of the second card, and when the PLMN _ REG _ REQ2 exists in the second non-access layer, judging whether the PLMN _ REG _ REQ2 is matched with the SERVICE _ REG _ CNF1 or not;

and S3, when the PLMN _ REG _ REQ2 is matched with the SERVICE _ REG _ CNF1, the second non-access stratum does not inform a second radio resource control layer of the second card to execute the PLMN _ REG _ REQ2 any more, and when the PLMN _ REG _ REQ2 is not matched with the SERVICE _ REG _ CNF1, the PLMN _ REG _ REQ2 is executed.

In this embodiment, the inventor finds that, in the dual-card network searching test, after the terminal returns to the normal network environment from the wireless or weak signal environment, one card often searches for the network, and another card cannot be searched for a long time, and it is necessary to wait for tens of seconds or even minutes to search for the other card. The reason behind the analysis by the inventor is that when the network environment is restored, the card with slow network residence is in a dormant state in the network searching process, or in an emergency network searching state, and the like. Because the network searching process consumes power, the network searching algorithm cannot search for the network all the time, otherwise, the power consumption of the machine is very fast, and the dormant state of some stages is very long; the emergency network searching state under the normal network environment is invalid network searching. Therefore, according to the network searching mechanism, a long time has passed when searching for a network frequency band where the network can reside next time. Based on this, if a card A is in a no-signal environment, the network searching fails naturally. For this process, another card B would naturally be blocked if it were to search for the network as well. If the blocked network searching request of the card B also searches the same network and network system, the network searching request blocked by the card B directly returns failure when the card A returns the network searching failure and the blocked network searching request of the card B is directly sent to a lower layer for execution, so that the network searching algorithm is carried out downwards, and the power consumption of one network searching request can be reduced. Therefore, in the embodiment, it is necessary to introduce a dual-card information sharing mechanism into the dual-card network searching mechanism to avoid the above problem, speed up the network searching speed, and reduce the power consumption of the network searching.

In the embodiment, the modification is performed on the existing screen searching frame. Specifically, referring to fig. 2, for an example in which two NAS modules exist in the dual-card terminal, when the network searching request received by the NAS is PLMN _ REG _ REQ, the command includes parameters PLMN (mcc, mnc) PLMN parameter, RAT radio access type parameter, and acq _ type request type parameter.

In this embodiment, the NAS generates the SERVICE _ REG _ REQ after processing, and forwards the SERVICE _ REG _ REQ to an RRC (Radio Resource Control) module corresponding to the RAT (Radio Access Type) for processing, the RRC module sends the SERVICE _ REG _ CNF to the NAS layer after network searching is completed, and the NAS layer processes the SERVICE _ REG _ CNF and returns the PLMN _ REG _ CNF to the NAS client. In the present embodiment, the above-described procedure is modified: specifically, referring to the second flowchart shown in fig. 3, the corresponding NAS2 module receives a network search failure notification of an RRC module of a certain RAT of the card 1, that is, RAT-RRC1, and if the SERVICE _ REG _ CNF prompts a failure and does not search for a network, notifies to process another NAS instance. For another NSA instance, whether the PLMN _ REG _ REQ is pending is queried, and if so, whether PLMN (mcc, mnc) public land mobile network parameters, RAT radio access type parameters, and acq _ type request type parameters match is determined. If the two NAS instances are matched, the other NAS instance does not inform the RRC to process the network searching request any more, and the failed PLMN _ REQ _ CNF is directly sent to the NAS client. Therefore, repeated network searching triggered by the same network searching request at the same time of two cards is effectively avoided, and power consumption is reduced.

The method has the advantages that when a second non-access layer corresponding to a second card of a terminal receives a SERVICE _ REG _ CNF1 first network searching failure message of a first card of the terminal at a first radio resource control layer, whether the second non-access layer has a to-be-executed PLMN _ REG _ REQ2 second network searching request is detected; when the second non-access layer does not have the PLMN _ REG _ REQ2, ending the network searching of the second card, and when the second non-access layer has the PLMN _ REG _ REQ2, determining whether the PLMN _ REG _ REQ2 is matched with the SERVICE _ REG _ CNF1; when the PLMN _ REG _ REQ2 matches the SERVICE _ REG _ CNF1, the second non-access stratum no longer notifies the second radio resource control layer of the second card to execute the PLMN _ REG _ REQ2, and when the PLMN _ REG _ REQ2 does not match the SERVICE _ REG _ CNF1, the PLMN _ REG _ REQ2 is executed. The network searching configuration scheme of the double cards is humanized, the network parking speed of the double-card terminal when the network is recovered from the non-network state is improved, and the use experience of a user is enhanced.

Based on the above embodiment, please refer to fig. 4, the method further includes:

s01, determining a first non-access layer corresponding to the first card and a second non-access layer corresponding to the second card;

and S02, receiving a PLMN _ REG _ REQ1 first network searching request of the first card by the first non-access layer, and receiving a PLMN _ REG _ REQ2 second network searching request of the second card by the second non-access layer.

Based on the above embodiment, please refer to fig. 5, the method further includes:

s11, when the PLMN _ REG _ REQ1 is processed in the first non-access stratum and a SERVICE _ REG _ REQ first SERVICE registration request is generated, forwarding the SERVICE _ REG _ REQ to the first radio resource control layer.

Based on the above embodiment, please refer to fig. 6, the method further includes:

s21, generating the SERVICE _ REG _ CNF1 when the first radio resource control layer fails in network searching;

s22, the first radio resource control layer sends the SERVICE _ REG _ CNF1 to the second radio resource control layer.

Based on the above embodiment, referring to fig. 7, the determining whether the PLMN _ REG _ REQ2 and the SERVICE _ REG _ CNF1 are matched includes:

s31, determining whether public land mobile network parameters, radio access type parameters, and request type parameters included in the PLMN _ REG _ REQ2 and the SERVICE _ REG _ CNF1 are the same;

and S32, if the two are the same, determining that the PLMN _ REG _ REQ2 is matched with the SERVICE _ REG _ CNF1, otherwise, determining that the PLMN _ REG _ REQ2 is not matched with the SERVICE _ REG _ CNF 1.

In the present embodiment, the PLMN (mcc, mnc) is 460 in the country, and mnc is different for different operators. When searching for the network, the double cards are matched with the PLMN (mcc, mnc) of the operator, and as long as the same RAT is searched in the same time period, one network searching can be reduced. Further, considering that PLMNs are all PLMNs (0, 0) when performing emergency search in the network searching algorithm, and that the whole network searching process takes 40 seconds or even longer under some RATs and acq _ types, in this embodiment, in order to enable different operator cards to search for networks effectively, this optimization may also reduce one network searching for different operator cards when performing emergency search at the same time, as long as the different operator cards are the same RAT and acq _ types.

It can be seen that the embodiment provides a power consumption saving scheme for searching a network by using two cards. Aiming at the situation that the dual-card terminal has no network for a long time, the purpose of reducing power consumption is achieved by removing repeated network searching operation through the same network searching request of the dual-card terminal at the same time. Therefore, when a user leaves the network-free environments, such as an elevator, a garage and a tunnel, after entering the network-free environments, the network can be parked on the double cards as soon as possible based on the scheme, and the situation that one card is behind the other card is avoided, so that the user experience is improved.
