Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of Internet, and particularly relates to a communication method and a communication device. BACKGROUND

[0002] At present, a wireless communication module of a terminal device usually pre-configures operator parameters according to different public land mobile networks (PLMNs) in a non-volatile memory (NV). When the terminal device is powered on, the configured operator parameters are automatically parsed from the NV according to a PLMN corresponding to an inserted identity identification card to obtain operator services. However, some operator parameters, such as internet protocol multimedia subsystem (IMS) user agents (UAs), cannot be directly obtained from the NV. Since all the operator parameters cannot be directly obtained from the NV, the time for obtaining the operator parameters is relatively long, and thus the network access time is prolonged. SUMMARY

[0003] Embodiments of the present application provide a communication method and a communication device, which can shorten the time for a terminal device to access a network and help improve the efficiency of the terminal device to access the network.

[0004] In an aspect, the embodiments of the present application provide a communication method, which includes:

[0005] obtaining configuration information from an application processor (AP), the configuration information including a plurality of operator parameters;

[0006] when an identity identification card is detected, determining a target public land mobile network (PLMN) corresponding to the identity identification card;

[0007] obtaining a target operator parameter corresponding to the target PLMN from the configuration information, the target operator parameter being used for accessing an internet protocol multimedia subsystem (IMS).

[0008] In the technical solution, the time for obtaining the operator parameters is reduced, and thus the network access time is shortened and the network access efficiency is improved.

[0009] In an embodiment, the method further includes: parsing the configuration information to obtain a first correspondence relationship between the plurality of operator parameters and type numbers. In the technical solution, the first correspondence relationship can be obtained by parsing the configuration information, and the corresponding operator parameter can be quickly determined based on the first correspondence relationship subsequently.

[0010] In an embodiment, obtaining the target operator parameter corresponding to the target PLMN from the configuration information includes:

[0011] determining a target type number corresponding to the target PLMN;

[0012] if the target type number exists in the first correspondence relationship, determining an operator parameter corresponding to the target type number from the configuration information;

[0013] determining the target operator parameter corresponding to the target PLMN as the operator parameter corresponding to the target type number.

[0014] In the technical solution, the operator parameter is determined according to the target type number, so that the AP side does not need to care about the PLMN, and only needs to determine the operator parameter according to the type corresponding to the PLMN, and the operator parameter can be determined more conveniently.

[0015] In an embodiment, the method further includes:

[0016] if the target type number does not exist in the first correspondence relationship, determining the target operator parameter corresponding to the target PLMN according to a second correspondence relationship between the PLMN and the operator parameter. In the technical solution, the second correspondence relationship is introduced, so that the operator parameter of the target PLMN can be found, and the dependence on the configuration information of the AP side is reduced.

[0021] determining a target PLMN set to which the target PLMN belongs, and determining a type number corresponding to the target PLMN set as the target type number corresponding to the target PLMN.

[0022] In the technical solution, the target type number corresponding to the target PLMN can be determined through the relationship between the PLMN and the type number, so that the target operator parameter can be subsequently determined from the first correspondence relationship based on the target type number.

[0023] In an embodiment, the operator parameter includes IMS user agent information.

[0024] In an embodiment, the configuration information is obtained from an application processor (AP), including:

[0025] When detecting that the terminal device is powered on, configuration information from the AP is received. In this technical solution, the AP side directly issues configuration information when the terminal device is powered on, so that the CP side does not need to wait for the configuration of the AP side, thereby shortening the acquisition time of the configuration information and realizing fast acquisition of operator parameters.

[0060] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0061] The embodiment of the present application provides a communication scheme, and the general principle of the communication scheme is as follows: after the terminal device is powered on, the CP can directly obtain configuration information from the AP side, then the CP determines a target public land mobile network (PLMN) corresponding to the SIM card when detecting a subscriber identity module (SIM), and obtains operator parameters corresponding to the target PLMN from the configuration information, and finally initiates a registration access request to the IMS network based on the target operator parameters, the registration access request can be used to request access to the IMS network. By obtaining the configuration information from the AP side when the terminal device is powered on, the CP can not need to wait for the AP to configure the corresponding operator parameters, thereby shortening the time for obtaining the operator parameters, and further shortening the network access time, which helps to improve the network access efficiency.

[0062] Please refer to Figure 1a , Figure 1a An architecture diagram of a communication system is provided in the embodiment of the present application. The communication system can include: a terminal device 101 and an Internet Protocol Multimedia Subsystem (IMS) 102. Figure 1a The number and form of devices shown are used for example and do not constitute a limitation on the embodiments of the present application, and in actual applications, for example, two terminal devices can be included. The terminal device 101 is a device with wireless transceiving function, and the terminal device can include, but is not limited to: a smart phone, a tablet computer, a smart wearable device, a smart voice interaction device, a smart home appliance, a personal computer, a vehicle-mounted terminal, a smart camera, a virtual reality device (such as an Augmented Reality (AR) device), and the like, and the present application does not limit this. The terminal device 101 can be fixed or mobile. In some embodiments of the present application, the terminal device 101 can also be a device with transceiving function, such as a chip module. The chip module can include a chip and can also include other discrete devices.

[0063] In an embodiment, the terminal device 101 can include an application processor (AP) and a communication processor (CP). As shown in FIG. 1, the terminal device 101 can include the AP and the CP. Figure 1bAs shown, the AP is mainly used to run the application in the terminal device 101 and provide the software functions of the terminal device 101. In this embodiment, the AP will have a carrier parameter configuration table pre-maintained. When the terminal device 101 is powered on, the carrier parameters can be directly obtained from the carrier parameter configuration table and sent to the CP.

[0064] like Figure 1c As shown, the CP (Content Provider) is mainly used to provide mobile communication functions for terminal device 101. The CP implements the entire network communication protocol stack. For example, data search, network search, calling, SMS service, ID card identification, and supplementary services are all specifically implemented on the CP. The CP can interact with the network, such as initiating access to the Public Land Mobile Network (PLMN) or the IMS network. When terminal device 101 is powered on, the CP can be responsible for accessing the corresponding PLMN. In some embodiments, the CP can obtain the operator parameters configured on the AP side and access the IMS network based on the operator parameters on the AP side.

[0065] IMS network 102 is a network architecture based on an IP network that provides voice and multimedia services. IMS is a multimedia control / call control platform on the packet domain (PS). IMS enables the PS to have some of the functions of the circuit domain (CS), supporting session-based and non-session-based multimedia services. In this embodiment, each operator builds an IMS network. The CP in terminal device 101 can register and access the corresponding operator's IMS network through operator parameters and use IMS services.

[0066] Based on the above communication system, this application provides a flowchart illustrating a communication method. Please refer to... Figure 2 The communication method can be executed by the CP in the terminal device. The communication method described in this embodiment may include the following steps S201-S203:

[0067] S201. Obtain configuration information from the application processor (AP). The configuration information includes multiple operator parameters.

[0068] The operator parameters may include: IMS User Agent information (i.e., IMS UA), operator frequency bands, etc. In one embodiment, when the terminal device is detected to be powered on, configuration information from the application processor (AP) can be received.

[0069] The configuration information includes a first correspondence relationship between a plurality of operator parameters and type numbers. After receiving the configuration information from the AP, the CP can parse the configuration information to obtain the first correspondence relationship between the plurality of operator parameters and the type numbers. The first correspondence relationship between the plurality of operator parameters and the type numbers can include the following two types: ① one operator parameter corresponds to one type number, that is, when the number of operator parameters is N, the number of type numbers is also N; N is a positive integer greater than 1 and equal to 1. For example, the number of operator parameters is 2, at this time, operator parameter 1 corresponds to type number 1; operator parameter 2 corresponds to type number 2. ② A plurality of operator parameters correspond to one type number. ③ Some of the plurality of operator parameters correspond to one type number, and the remaining operator parameters correspond to another type number. The type number can be set according to requirements, for example, the type number can be a character, a number, or a combination of characters and numbers.

[0070] In an embodiment, the configuration information is obtained by integrating the first correspondence relationship between the plurality of operator parameters and the type numbers according to a preset delimiter. At this time, the manner of parsing the configuration information to obtain the first correspondence relationship between the plurality of operator parameters and the type numbers can include: parsing the configuration information according to the preset delimiter to obtain the first correspondence relationship between the plurality of operator parameters and the type numbers. The preset delimiter can be set according to requirements, for example, the preset delimiter can be ||, & and the like. For example, the configuration information is obtained by integrating the first correspondence relationship between the plurality of operator parameters and the type numbers according to the preset delimiter "||", for example, the configuration information is type number 1 (operator parameter 1) || type number 2 (operator parameter 2) || type number 3 (operator parameter 3); that is, the CP parses the configuration information according to the preset delimiter to obtain type number 1 and the operator parameter 1 corresponding to type number 1, type number 2 and the operator parameter 2 corresponding to type number 2, type number 3 and the operator parameter 3 corresponding to type number 3.

[0071] Optionally, after parsing the configuration information to obtain the first correspondence relationship between the plurality of operator parameters and the type numbers, the first correspondence relationship can be stored in the local storage space of the terminal device, so that the first correspondence relationship can be directly obtained from the local space in the future, facilitating quick access to operator parameters.

[0072] S202, when the identity recognition card is detected, determining a target public land mobile network (PLMN) corresponding to the identity recognition card.

[0073] In a specific implementation, when the identity recognition card (such as a SIM card) is detected, the identity recognition card can be identified to obtain a target PLMN corresponding to the identity recognition card. The target PLMN refers to the network of a target operator, that is, the target PLMN can be a mobile network, a telecommunications network, or a Unicom network.

[0074] S203, obtain, from the configuration information, a target operator parameter corresponding to the target PLMN, the target operator parameter being used for accessing an IMS (Internet Protocol Multimedia Subsystem). The IMS accessed here refers to an IMS corresponding to the target PLMN.

[0075] In one embodiment, each operator parameter corresponds to one PLMN; the CP can directly obtain, from the configuration information, the target operator parameter corresponding to the target PLMN.

[0076] In another embodiment, the configuration information includes a first correspondence relationship between a plurality of operator parameters and type numbers, and obtaining, from the configuration information, the target operator parameter corresponding to the target PLMN can include: determining a target type number corresponding to the target PLMN, obtaining the first correspondence relationship from a local storage space, and determining whether the target type number exists in the first correspondence relationship; if it is determined that the target type number exists in the first correspondence relationship, determining an operator parameter corresponding to the target type number from the configuration information, and determining the target operator parameter corresponding to the target PLMN as the operator parameter corresponding to the target type number. If it is determined that the target type number does not exist in the first correspondence relationship, obtaining a second correspondence relationship between a PLMN and an operator parameter, and determining the target operator parameter corresponding to the target PLMN according to the second correspondence relationship between the PLMN and the operator parameter.

[0077] The determination of whether the target type number exists in the first correspondence relationship can be: matching the target type number with type numbers in the first correspondence relationship respectively, and if the target type number matches a type number in the first correspondence relationship, it is determined that the target type number exists in the first correspondence relationship. If the target type number does not match a type number in the first correspondence relationship, it is determined that the target type number does not exist in the first correspondence relationship.

[0078] In one embodiment, the determination of the target type number corresponding to the target PLMN can include: obtaining one or more PLMN sets, one PLMN set corresponding to one type number, and one PLMN set including at least one PLMN. Then the CP determines a target PLMN set to which the target PLMN belongs, and determines a type number corresponding to the target PLMN set as the target type number corresponding to the target PLMN.

[0079] Optionally, the CP is combined by two configuration manners. The first configuration manner is to classify the PLMNs of the same type number to obtain a PLMN set corresponding to a type number, i.e., the PLMNs in the PLMN set correspond to the same type number. For example, the PLMN set 1 includes the PLMN 1 and the PLMN 2, and the PLMN 1 and the PLMN 2 correspond to the type number 1; the PLMN set 2 includes the PLMN 3 and the PLMN 4, and the PLMN 3 and the PLMN 4 correspond to the type number 2; wherein the PLMNs of the same type number correspond to the same operator parameter splicing manner, and the PLMNs of different type numbers correspond to different operator parameter splicing manners. For example, the operator parameter splicing manner of the PLMN 1 is "operator parameter 46001; UA1", and the operator parameter splicing manner of the PLMN 2 is "UA2: 46002". It can be seen that the operator parameter splicing manners of the two are different, and the PLMN 1 and the PLMN 2 correspond to different type numbers, respectively.

[0080] The second configuration manner is to configure a second correspondence relationship between the PLMNs and the operator parameters, and save the second correspondence relationship into the non-volatile memory. The configured second correspondence relationship between the PLMNs and the operator parameters can reduce the dependence of the CP on the configuration information of the AP side to a certain extent.

[0081] In one embodiment, when the terminal device is restarted, the configuration information can be reacquired from the AP, and when the identity recognition card is detected, the target PLMN corresponding to the identity recognition card is determined. The target operator parameter corresponding to the target PLMN is acquired from the configuration information, and the target operator parameter is used to access the IMS. At this time, reacquiring the configuration information can ensure that the latest configuration information is acquired. In another embodiment, when the terminal device is restarted, the first correspondence relationship is stored in the local storage space of the terminal device; when the identity recognition card is detected, the target PLMN corresponding to the identity recognition card is determined, and after the target type number of the target PLMN is determined, the first correspondence relationship stored in the local storage space can be directly acquired, and whether the target type number exists in the first correspondence relationship is judged to acquire the target operator parameter corresponding to the target PLMN.

[0082] The first correspondence relationship can be set with an effective time length when stored in the local storage space. If the storage time length of the first correspondence relationship exceeds the effective time length, the configuration information can be directly reacquired from the AP.

[0083] In an embodiment, when the number of target SIM cards is multiple, the corresponding operator parameters of the target PLMN corresponding to each identity card can be obtained from the configuration information. For example, identity card 1 corresponds to target PLMN 1, and the corresponding operator parameters of target PLMN 1 can be obtained from the configuration information; identity card 2 corresponds to target PLMN 2, and the corresponding operator parameters of target PLMN 2 can be obtained from the configuration information. Then the CP initiates an access request to the IMS system corresponding to target PLMN 1 with the corresponding operator parameters of target PLMN 1, and initiates an access request to the IMS system corresponding to target PLMN 2 with the corresponding operator parameters of target PLMN 2.

[0084] In another embodiment, the priorities of target PLMN 1 and target PLMN 2 can be determined. If the priority of target PLMN 1 is higher than that of target PLMN 2, an access request can be initiated to the IMS network corresponding to target PLMN 1 based on the corresponding operator parameters of target PLMN 1; if the priority of target PLMN 1 is lower than that of target PLMN 2, an access request can be initiated to the IMS network corresponding to target PLMN 2 based on the corresponding operator parameters of target PLMN 2.

[0085] It should be understood that the number of target PLMNs described above is only an example of 2, and the number of target PLMNs can be greater than 2; at this time, the operator parameters corresponding to the target PLMN with higher priority can be preferentially considered to initiate an access to the corresponding IMS.

[0086] In the embodiment of the present application, the configuration information is obtained from the application processor AP, and the configuration information includes multiple operator parameters; when the identity card is detected, the target public land mobile network (PLMN) corresponding to the identity card is determined; the target operator parameters corresponding to the target PLMN are obtained from the configuration information, and the target operator parameters are used for accessing the Internet protocol multimedia subsystem (IMS). The configuration information can be obtained in advance, so as to shorten the time for obtaining the configuration information, thereby shortening the time for the terminal device to access the network, and helping to improve the efficiency of the terminal device to access the network.

[0087] Please refer to Figure 3 , Figure 3 Another flowchart of a communication method provided by the embodiment of the present application is provided. The communication method is mainly introduced from the interaction between the AP and the CP. In the embodiment, the operator parameters mainly include IMS UA as an example, and the communication method can include the following steps S301-S304:

[0088] S301, when the terminal device is detected to be powered on, the AP sends configuration information to the CP, and the configuration information can include multiple IMS UAs.

[0089] In one embodiment, the AP is pre-configured with an operator parameter configuration table, in which a type number is defined to correspond to an IMS UA. When detecting that the terminal device is powered on, the AP can obtain a first correspondence between the type number and a plurality of IMS UAs from the operator parameter configuration table, and integrate the obtained first correspondence between the type number and the plurality of IMS UAs according to a preset delimiter to obtain configuration information. Alternatively, the first correspondence between the type number and the plurality of IMS UAs can also be integrated according to the preset delimiter and the type number to obtain the configuration information. For example, the first correspondence includes that each IMS UA corresponds to a type number; the AP starts from type number 1, and integrates the plurality of IMS UAs according to "type number 1||type number 2||type number 3||type number N" using the preset delimiter to obtain the configuration information.

[0090] The first correspondence between the type number and the IMS UA in the operator parameter configuration table can be dynamically updated, and the dynamic update can include adding an IMS UA corresponding to a type number and deleting an IMS UA corresponding to a type number. The dynamic update can effectively ensure that the terminal device can initiate access registration with the latest IMS UA.

[0091] S302, the CP parses the configuration information to obtain a first correspondence between a plurality of IMS UAs and type numbers.

[0092] In a specific implementation, the CP can receive the configuration information sent by the AP, parse the configuration information according to the preset delimiter, obtain the first correspondence between the plurality of IMS UAs and the type numbers, and store the first correspondence in a local storage space.

[0093] S303, when detecting the identity recognition card, determining a target PLMN corresponding to the identity recognition card.

[0094] In one embodiment, when the number of identity recognition cards is a plurality (for example, two), the target PLMN corresponding to each identity recognition card can be determined respectively.

[0095] S304, obtaining a target IMS UA corresponding to the target PLMN from the configuration information, and the target IMS UA is used to access an Internet Protocol Multimedia Subsystem (IMS).

[0096] In one embodiment, the CP has two configurations: the first configuration is to pre-configure a second correspondence between a PLMN and an IMS UA in a non-volatile memory, so that the corresponding IMS UA can be configured, and thus the IMS UA on the AP side is not needed. The second configuration is to classify the PLMNs of the same type number to obtain a PLMN set corresponding to a type number.

[0097] In an embodiment, obtaining the target IMS UA corresponding to the target PLMN from the configuration information can include: determining a target type number corresponding to the target PLMN, obtaining a first correspondence relationship from a local storage space, and determining whether the target type number exists in the first correspondence relationship; if it is determined that the target type number exists in the first correspondence relationship, determining an IMS UA corresponding to the target type number from the configuration information, and determining the target IMS UA corresponding to the target PLMN as the IMS UA corresponding to the target type number; and if it is determined that the target type number does not exist in the first correspondence relationship, obtaining a second correspondence relationship between a PLMN and an IMS UA, and determining the target IMS UA corresponding to the target PLMN according to the second correspondence relationship between the PLMN and the IMS UA.

[0098] In the embodiments of the present application, the configuration information is received from an AP, and the configuration information includes a plurality of operator parameters; when an identity recognition card is detected, a target public land mobile network (PLMN) corresponding to the identity recognition card is determined; and a target operator parameter corresponding to the target PLMN is obtained from the configuration information, and the target operator parameter is used for accessing an Internet Protocol Multimedia Subsystem (IMS). The configuration information can be obtained in advance, so that the time for the terminal device to obtain the operator parameter is shortened, and the time for the terminal device to access the network is further shortened, thereby improving the efficiency of the terminal device in accessing the network.
