Technical Field
The present invention relates to the field of communications technologies, and in particular, to a network configuration method and apparatus for a terminal, a storage medium, a terminal, and a baseband chip.
Background
Operator networks in different regions have different network parameter configurations, such as the size of the maximum transmission unit of a supported mobile system, a licensed frequency band, a data/Internet Protocol Multimedia Subsystem (IMS) voice service, and an encryption algorithm required to be started, according to their own plans and policies. In addition, the operator (such as mobile, internet, telecommunication, vodafone, etc.) can also customize the behavior of the terminal based on its own network conditions, such as a service retry mechanism in some abnormal scenarios.
With the development of mobile communication technology, an operator of a serving cell in which a terminal (e.g., a mobile phone, a mobile computer, a smart watch, etc.) is located may change due to factors such as self-movement or cell reselection during a communication process. If the operating parameters used by the terminal are not consistent with the operator network parameters, various communication problems may occur. For example, if the size of an IMS Voice data packet of a terminal is larger than network configuration, the maximum transmission unit of an IMS Voice service may cause a problem of packet loss and even a call failure of the IMS Voice service (Voice over LTE, called Voice for short).
Conventional terminal configuration usually configures a set of specific terminal parameter files, i.e. non-volatile memory (NV) files, according to network parameters of an operator, and if there are many shipping areas of a client, the former configuration means that the client needs to maintain dozens of NV files for a baseband (Modem) version to include NV parameters of each operator.

Optionally, the preset storage location may further store one or more sets of default (default) network parameters, and when the terminal cannot match the appropriate operator network parameters, the default network parameters may be used. The default network parameters are a set of some common parameters that are preset.
Optionally, the PLMN parameter used by the terminal includes a home PLMN parameter of the core network side and an access PLMN parameter of the access network side.
The Home PLMN parameter refers to a parameter generally stored on the public PLMN (Home PLMN, abbreviated as HPLMN) side of the core network, and is configured with a Subscriber Identity Module (SIM) or a Universal Subscriber Identity Module (USIM), where such a parameter is generally a parameter stored on the HPLMN side of the core network and denoted as SIM _ DATA.
The Visited PLMN parameter refers to a parameter configured with the currently camped PLMN, and such a parameter is generally a parameter stored in the access network or in the Visited PLMN (VPLMN) side according to the core network architecture, and is referred to as PLMN _ DATA.

For example, when a mobile phone equipped with a SIM/USIM card of a china mobile roams to a cell covered by wadfeng, network communication can be achieved by the SIM/USIM card of the china mobile through a roaming mode in the cell covered by wadfeng.
Optionally, the preset storage location is located in a baseband (Modem) chip of the terminal.
Before the terminal leaves a factory, a Modem version is burned in a baseband chip of the terminal, and the Modem version comprises multiple sets of PLMN parameters corresponding to the PLMN information. The PLMN parameters corresponding to the multiple sets of PLMN information may be from configuration tables and outfield test verification data issued by an operator.
In one embodiment, the method described in fig. 1 further comprises: receiving a request for updating information in a preset storage position from a server side; and when an instruction for starting updating is obtained, obtaining updating data from the server, and updating the information in the preset storage position by using the updating data.

When the terminal is to acquire the parameters in the preset storage location, the terminal can use the information of the operator to perform querying and acquisition.
Optionally, a network characteristic Database (Database or Database Layer for short) for storing PLMN parameters corresponding to multiple sets of PLMN information may be established at the preset storage location.
Through the method illustrated in fig. 1, the terminal can select the network configuration parameters of the operator to be used through PLMN parameters corresponding to multiple sets of PLMN information stored in the preset storage location, so as to automatically adapt to the network configurations of multiple operators. And the terminal can support the combined use mode of the home PLMN parameter and the visited PLMN parameter to support the situation that the resident cell is inconsistent with the provider of the SIM card/USIM card of the resident cell, so as to adapt to the roaming scene of the terminal among a plurality of operators.

And if the home PLMN parameter used by the terminal is not matched with the operator of the SIM card/USIM card, the terminal needs to replace the used home PLMN parameter. The terminal acquires PLMN parameters (namely updated PLMN parameters) corresponding to the operators of the SIM card/USIM card from a preset storage position as new used home PLMN parameters.
In this embodiment, the SIM card/USIM card used by the terminal may be changed after the terminal is powered off or turned on, or when the SIM card/USIM card is hot-plugged, and at this time, the terminal needs to adapt to adjust the home PLMN parameter used by the terminal.
