In an embodiment, as shown in fig. 2, a network registration method is provided, which is described by taking the application of the method to the terminal in fig. 1 as an example, and includes the following steps:
The power-on operation may be an operation in which the terminal responds to the user to power on the device, and when the user powers on the terminal, the user may simultaneously search for a mobile Country code and read cache data in the user identity card, where the mobile Country code is MCC (mobile Country code), the MCC represents a Country to which the mobile user belongs and may be a 3-digit digital code, for example, the mobile Country code corresponding to china is 460, and the user identity card may be a SIM card, and a terminal device having a mobile communication function can be used by installing the SIM card. The service terminal of the network service providing object stores the information of the digital mobile phone client, the encrypted key and the telephone directory of the user, the SIM card can be used for the identity authentication of the mobile network client and encrypting the voice information when the client calls. The search may be a first frequency sweep performed at power-on, which refers to frequency band (band) scanning, i.e., performing mobile network search in a frequency band.
Specifically, when a user starts the device, the terminal responds to the starting operation of the user, mobile network search is performed according to a network protocol, the terminal obtains a mobile country code through search of an access stratum (AS Layer) in the network protocol Layer in the first frequency sweeping process, then the mobile country code is reported to a non-access stratum (NAS Layer) in the network protocol Layer, data processing is performed by the non-access stratum and transmitted to the terminal, meanwhile, the terminal reads cache data in the user identity identification card during starting, information in the user identity identification card is obtained, and the access stratum and the non-access stratum are different protocol layers in a network communication protocol. The access stratum is a protocol layer for directly performing network connection and access, and is intended to allow a terminal to connect to a network, and for example, a process flow of the access stratum includes a process flow of mobile network selection, cell selection, radio resource management, and the like. The non-access layer is a functional layer of the mobile network and the terminal equipment and is used for transmitting signaling and data.
And step 204, obtaining an available mobile network list according to the mobile network matched with the mobile country code and the mobile network corresponding to the user identity identification card.
The mobile network matched with the mobile country code is a mobile network matched from a mobile network list of network service providing objects according to the obtained mobile country code, and the mobile network corresponding to the user identity identification card is a mobile network associated with the user identity identification card in an association list of each network service object.
Specifically, the terminal obtains a mobile network matched with the mobile country code from the mobile network list and obtains a mobile network corresponding to the subscriber identity card from the subscription, and the terminal finally obtains an available mobile network list according to the mobile network matched with the mobile country code and the mobile network corresponding to the subscriber identity card.
The terminal reads the user identity identification card, then performs network search according to the protocol standard of the 3GPP protocol TS23.122, and performs search according to the priorities of different mobile networks, when the cache data in the user identity identification card is read and the user control mobile network (UPLMN) in the cache data is acquired, the terminal replaces the content in the user control mobile network file cached in the user identity identification card with the obtained available mobile network list, and when performing subsequent network search, the terminal uses the content in the user control mobile network file cached after current replacement, namely performs network search according to the available mobile network list, and the network search is network search, for example, mobile network search.
Specifically, after the terminal reads the cache data in the user identification card, the file in the user controlled mobile network in the cache data is obtained, the terminal replaces the content in the file in the user controlled mobile network with the available mobile network list, and rewrites the replaced file in the user identification card.
And step 208, performing mobile network search according to the content-replaced user control mobile network file, and performing network registration based on the target mobile network when the target mobile network matched with the available mobile network with the highest priority in the available mobile network list exists in the searched mobile network.
The available mobile network with the highest priority in the available mobile network list may be the first mobile network in the available mobile network list obtained by performing the optimal ordering. The network registration is performed on the premise that network searching is performed, for example, by frequency sweeping, that is, searching for a mobile network in a frequency band, when a searched mobile network has a matching mobile network in an available mobile network list, the terminal may initiate registration.
Specifically, a registration request is initiated by a non-access stratum, an access stratum is instructed to perform a registration frequency sweep action, specifically, a terminal performs mobile network search in a frequency band according to a user control mobile network file replaced by content, and when a target mobile network matched with an available mobile network with the highest priority in an available mobile network list exists in a mobile network obtained by the search of the access stratum, network registration is performed based on the target mobile network.
In the network registration method, the frequency band is searched to obtain the mobile country code by responding to the starting operation, the user identity identification card is read, the obtained mobile country code and the user identity identification card are used for determining the available mobile network list, the subsequent search time is reduced, the available mobile network list can be obtained according to the mobile network matched with the mobile country code and the mobile network corresponding to the user identity identification card, and the content in the user control mobile network file is replaced by the available mobile network list by obtaining the user control mobile network file in the cache data; the mobile networks in the available mobile network list are used for matching, so that a large number of invalid mobile networks which cannot be matched can be effectively avoided being searched, the mobile network search is carried out in a targeted mode, the search time is shortened, the mobile network frequency band search is carried out according to the mobile network file controlled by the user, when a target mobile network which is matched with the available mobile network with the highest priority in the available mobile network list exists in the mobile networks obtained through the frequency band search, a target mobile network with good signal quality can be quickly searched, the search time is shortened, and the network registration can be quickly carried out based on the target mobile network.
In one embodiment, as shown in fig. 3, the step 204 of determining the list of available mobile networks according to the mobile network matching the mobile country code and the mobile network corresponding to the subscriber identity card includes:
The network service providing object may be an object providing network service, specifically a global operator, and the network service provided by the operator, the association list of each network service providing object may be a subscription list of subscription information corresponding to each operator in the global operator, the subscription list refers to a list composed of subscription information related to the global operator, the mobile network is a PLMN, each mobile network has a corresponding mobile network identifier, and the mobile network identifier represents the mobile network.
Specifically, the terminal obtains a mobile network list (PLMNList) of network service providing objects and an association list (SignupList) of each network service providing object, for example, a mobile network list (PLMNList) of a global operator and a subscription list (SignupList) of each operator may be obtained for the terminal, and the mobile network list includes a mobile network identifier corresponding to a mobile network provided by each operator.
The mobile country code is MCC searched by the terminal, the association list may be SignupList of each operator, and the correspondence between the subscriber identity cards is that of the SIM cards. Specifically, the terminal obtains a first group of mobile networks matching the mobile country code from a mobile network list of the network service providing object, and obtains a second group of mobile networks corresponding to the subscriber identity card from an association list, for example, the terminal may obtain the first group of mobile networks matching the MCC from a PLMNList of a global operator, and obtain the second group of mobile networks subscribed to the SIM card from a SignupList.
The aggregation may be a union of matching mobile networks existing in both the two groups of mobile networks, and may also be referred to as an "and" or "and", that is, the finally obtained mobile networks exist in both the first group of mobile networks and the second group of mobile networks, and the finally obtained mobile networks are combined into an available mobile network list. Specifically, the terminal collects the matched mobile networks in the first group of mobile networks and the second group of mobile networks, and obtains an available mobile network list (availablepmnlist) according to the matched mobile networks in the two groups of mobile networks.
In this embodiment, the first group of mobile networks matching the mobile country code is acquired from the mobile network list by acquiring the mobile network list and the association list of each network service providing object. And acquiring a second group of mobile networks corresponding to the user identification card from the association list. And collecting the first group of mobile networks and the second group of mobile networks to obtain an available mobile network list, and replacing the content in the user control mobile network file with the available mobile network list by acquiring the user control mobile network file in the cache data. The mobile networks in the available mobile network list are used for matching, so that a large number of invalid mobile networks which cannot be matched can be effectively avoided being searched, the mobile networks are searched in a targeted manner, and the searching time is shortened.
In one embodiment, as shown in fig. 4, step 302, obtaining a mobile network list and an associated list of each network service providing object, includes:
The initial mobile network list may be an initial PLMNList of global operators, and the initial association list of each network service provider may be an initial signup list of each operator. Specifically, the terminal acquires a mobile network list of network service providing objects and an association list of each network service providing object, for example, may acquire an initial PLMNList of a global operator and an initial SignupList of each operator.
The network parameter may be a parameter related to a mobile network of an operator, the network coverage area parameter may be a network coverage area of the mobile network corresponding to the operator, and the weight parameter may include a related tariff weight, for example, for lte (long Term evolution), coverage includes information such as signal quality RSRP and SINR, and tariff includes tariff information such as traffic or voice tariff. Each mobile network in the mobile network list and the mobile networks in the association list has a corresponding mobile network identifier, and the ranking can be based on the combination of the network coverage area parameter and the weight parameter, and the preferred mobile network has wide coverage and low cost. Specifically, the terminal sorts the mobile network list of the initial network service providing object and the mobile network identifier in the initial association list according to at least one of the network coverage area parameter and the weight parameter corresponding to each network service object, to obtain a mobile network list of the sorted network service providing object and an association list of each network service providing object, for example, the terminal sorts the mobile network identifiers in the initial PLMNList and the initial SignupList of the global operator according to the network coverage area parameter and the weight parameter corresponding to each operator, to obtain the PLMNList of the global operator and the SignupList of each operator.
In this embodiment, the initial mobile network list and the initial association list of each network service providing object are obtained, and the mobile network identifiers in the initial mobile network list and the initial association list are respectively sorted according to the network parameters corresponding to each network service providing object to obtain the mobile network list and the association list of each network service providing object, so that the available mobile network list can be obtained according to the sorted mobile network list and association list, and the subsequent search time is reduced.
In one embodiment, as shown in fig. 5, step 306, aggregating the first group of mobile networks and the second group of mobile networks to obtain the list of available mobile networks includes:
at step 502, available mobile networks with matching mobile network identifications are identified in the first set of mobile networks and the second set of mobile networks.
Each mobile network has a corresponding mobile network identifier, and there are matched mobile networks in the first group of mobile networks and the second group of mobile networks, specifically, the mobile network identifiers of the first group of mobile networks and the second group of mobile networks of the terminal are identified to obtain available mobile networks with matched mobile network identifiers in the first group of mobile networks and the second group of mobile networks.
At step 504, a list of available mobile networks is constructed that includes the available mobile networks.
Specifically, the terminal constructs an available mobile network list containing available mobile networks according to the available mobile networks with matching mobile network identifications in the first group of mobile networks and the second group of mobile networks.
In this embodiment, an available mobile network list including available mobile networks is constructed by identifying available mobile networks in which mobile network identifiers in a first group of mobile networks and a second group of mobile networks are matched, and contents in a user control mobile network file cached in the user identification card can be replaced with the available mobile network list; the mobile networks in the available mobile network list are used for matching, so that a large number of invalid mobile networks which cannot be matched can be effectively avoided being searched, the mobile networks are searched in a targeted manner, and the searching time is shortened.
In one embodiment, the user controlled mobile network file in the cache data is obtained, and the content in the user controlled mobile network file is replaced by the available mobile network list.
Specifically, a user control mobile network file in the cache data of the user identification card is obtained; and replacing the content in the user control mobile network file by the available mobile network list, and caching the replaced content into the user identification card. For example, the terminal may first read a UPLMN file in the SIM card; and then the terminal replaces the contents in the UPLMN file with the AvailablePLLMNList, and finally the terminal caches the replaced contents in the SIM card.
In this embodiment, the content in the user control mobile network file cached in the user identification card is replaced with the available mobile network list; the mobile networks in the available mobile network list are used for matching, so that a large number of invalid mobile networks which cannot be matched can be effectively avoided being searched, the mobile networks are searched in a targeted manner, and the searching time is shortened.

Specifically, when there is no target mobile network matching the available mobile network with the highest priority in the availableplmnnlist in the mobile networks obtained by the search in the frequency band, the terminal performs network registration according to the mobile network matching the available mobile network with the second highest priority in the availableplnlist.

For example, there are first, second, and third networks … … N network in availablepllmnlist with a priority order from high to low, i.e., the first network has a higher priority than the second network, the second network is higher than the third network, and the third network is higher than the N network. First, the first network is the available mobile network with the highest priority, and the first network is matched with the searched mobile network. When the first network is successfully matched with the searched mobile network, network registration is carried out based on the first network; and when the first network is not successfully matched with the searched mobile network, selecting a second network in the AvailablePLMNList, taking the second network as the available mobile network with the highest priority again, and matching the second network with the searched mobile network.
