Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a network searching method, a network searching device, a storage medium and a terminal.
The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
In this embodiment, a description will be given from the perspective of a network search apparatus, where the network search apparatus may be specifically integrated in a network device, and the network device may be a server or a terminal; the terminal can comprise a smart phone, a tablet computer and other devices.
A network search method, comprising: receiving a network searching instruction; performing network search according to the network search instruction to obtain a mobile country code, wherein the network search instruction indicates to search a registered public land mobile network; judging whether the mobile country code belongs to a country of an operator with a signed roaming agreement; if so, stopping network search, and connecting the target public land mobile network according to a preset network information set, wherein the preset network information set comprises the public land mobile network of the operator with the signed roaming agreement, the wireless access technology and the frequency band information supported by the terminal.
Referring to fig. 1, fig. 1 is a first flowchart of a network searching method according to an embodiment of the present disclosure. The method comprises the following specific processes:
step 101, receiving a network search instruction.
In some embodiments, when the terminal device moves to an operator network that subscribes to a roaming agreement, it is necessary to enable the terminal to perform a network entry procedure in a roaming scenario through network search. Roaming refers to that when a cellular mobile terminal user leaves a current region or country, the cellular mobile terminal user can still use terminal equipment in other regions or countries through network search, and roaming application ranges between domestic cities which are compatible in network systems and contain public land mobile networks or between regions and countries which sign roaming agreements.
The public Land Mobile network refers to a plmn (public Land Mobile network), such as china Mobile, telecommunications, and telecommunications. The PLMN is composed of MCC (Mobile CountryCode), such as 460 in china and 404 in india; MNC (Mobile Network Code), for example, unicom is 01, so the PLMN in china unicom is 46001. It is noted that MCC is combined with MNC to represent the network operator of only one mobile terminal device.
In some embodiments, the network types available for network search include many types, for example, RPLMN (Registered PLMN) is a PLMN Registered by the terminal device before the previous power-off or network disconnection, HPLMN (Home PLMN, PLMN owned by the user), ehplmn (equivalent HPLMN) is an equivalent HPLMN, UPLMN (user controlled PLMN), OPLMN (Operator controlled PLMN), other network types, and the like.
And 102, performing network search according to the network search instruction to obtain a mobile country code, wherein the network search instruction indicates to search the registered public land mobile network.
In some embodiments, the network search is performed according to the network search instruction received in step 101, and in a normal case, after the terminal device is powered on, PLMN search is required to be performed, and normal services can be obtained from the network only after a PLMN is successfully registered, so that when a user moves between regions or countries using the terminal device, a large number of PLMN connection history records registered in the past network use process are stored, and when the user moves to a new region or country, the registered PLMN generates a network search list, and uses the PLMN in the list as a network connection priority option for the user to select.
In step 101, a PLMN obtained by performing a network search by a user is described, where the PLMN includes a mobile country code MCC of a current search location, and the MCC corresponds to each mobile terminal device one to one.
And 103, judging whether the mobile country code belongs to the country of the operator with the roaming agreement signed.
In some embodiments, before determining whether the mobile country code belongs to a country in which a roaming agreement operator has been signed, the step of obtaining roaming service information is performed, and includes:
sending an acquisition instruction for opening a roaming service to an operator who has signed a roaming agreement in a short message form; and acquiring roaming service information of the operator with the signed roaming agreement based on the acquisition instruction, wherein the roaming service information comprises the public land mobile network of the operator with the signed roaming agreement, a wireless access technology and frequency band information supported by the terminal.
Wherein the above terms include: RAT (Radio Access Technology ) and Band (frequency Band) specifically refer to frequency bands supported by a terminal.
The method for sending the acquisition instruction may also be sending in the form of an email, or sending the acquisition instruction through terminal application chat software.
In some embodiments, since the MCC is obtained from the registered PLMN list by searching the network in step 102, the network to which the MCC belongs also belongs to the registered PLMN. When the end user moves to a new region or country, and when the network access process is executed, the network searching sequence is automatic network selection according to the 3GPP (3rd generation partnership Project) protocol specification, and there is a network selection priority sequence, so that if the network is selected from the registered PLMN list, the automatic network selection process according to 3GPP is omitted, and the user performs connection with networks of equal priority in the registered PLMN list.
And step 104, if so, stopping network search, and connecting the target public land mobile network according to a preset network information set, wherein the preset network information set comprises the public land mobile network of the operator with the signed roaming agreement, the radio access technology and the frequency band information supported by the terminal.
In some embodiments, the purpose of "determining whether the mobile country code belongs to the country of the subscribed roaming operator" in step 103 is to directly stop the search when the obtained MCC belongs to the country of the subscribed roaming operator, because the network to which the MCC belongs to the registered PLMN and supports the roaming service at the current location, and perform the network connection step according to the information of the frequency band supported by the public land mobile network, the radio access technology, and the terminal of the subscribed roaming operator in the roaming service information obtained in step 103.
The rat (radio Access technology) generally includes 2G, 3G, 4G, 5G, and so on; the frequency band information supported by the terminal generally includes 2G, 3G, 4G, and 5G frequency bands.
In some embodiments, the manner of determining that the target public land mobile network is connected according to the preset network information set may be:
determining a candidate network according to the network information set; determining the signal strength of each candidate network supporting roaming service connection; prioritizing network connections for each of the candidate networks based on the signal strengths; ranking public land mobile networks of operators in the network information set having entered into a roaming agreement based on the network connection priority.
The stronger the signal strength of the roaming service connection supporting in the candidate network becomes the preferred choice of network connection, and when the candidate network arranged in the front is unable to connect, the connection is performed according to the priority from strong to weak of the signal strength, aiming at selecting the optimal network supporting the roaming service for connection.
In some embodiments, the manner of determining that the target public land mobile network is connected according to the preset network information set may also be:
determining a candidate network according to the network information set; determining the charge height information of each candidate network under a preset charge deduction standard; and arranging the public land mobile network of the operator which has signed the roaming agreement in the network information set based on the expense high-low information.
The preset fee deduction standard can be based on the consumption of traffic flow when the user uses roaming, or the consumption of telephone fee when the user uses roaming, or the monthly fee consumed by roaming service handled by the user.
In some embodiments, this may also occur: if the mobile country code does not belong to the country of the operator with the roaming agreement, searching other networks supporting the roaming service according to each wireless access technology and frequency band information supported by the terminal equipment.
If there is no operator signing a roaming agreement with the current location in all registered PLMNs of the user, the network search needs to be performed in the network supported by the currently used terminal device according to the arrangement sequence of automatic network selection specified by the 3GPP protocol.
In summary, taking the example that the terminal moves to another country, the process of the terminal implementing the optimized roaming access is as follows: when a user terminal moves to a network of a foreign operator signing a roaming agreement, firstly, a user puts forward a roaming service application for opening the foreign operator to the operator, and acquires roaming service information of the foreign operator in a short message mode; then, the terminal receives a service information short message of an operator about a roaming operator, wherein the content of the short message comprises PLMN, RAT and Band of the roaming operator; then starting to search RPLMN, and stopping searching RPLMN when the MCC of the current network is searched to be the country of the signed roaming agreement operator; then, searching the PLMN according to the RAT and Band of the operator signing the roaming agreement, and registering the searched PLMN with a roaming PLMN network; if the target network cannot be searched by searching in the above manner, other networks are searched according to all the RATs and bands supported by the terminal.
The network searching method provided by the embodiment comprises the following steps: the terminal receives a network searching instruction, and carries out network searching according to the network searching instruction to obtain a mobile country code, wherein the network searching instruction indicates to search a registered public land mobile network; then, judging whether the mobile country code belongs to the country of the operator with the roaming agreement; if so, stopping network search, and connecting the target public land mobile network according to a preset network information set, wherein the preset network information set comprises the public land mobile network of the operator with the signed roaming agreement, the wireless access technology and the frequency band information supported by the terminal. The embodiment aims to acquire the roaming service message through the short message, optimize the process of signing the roaming agreement operator on registration, select the network from the operator signing the roaming agreement for connection, reduce unnecessary network search and improve the network searching rate.
The method described in the previous embodiment is further detailed by way of example.
The present embodiment will be described from the perspective of a network search apparatus that is specifically integrated in a smartphone. Referring to fig. 2, fig. 2 is a second flowchart illustrating a network searching method according to an embodiment of the present application. A network searching method comprises the following specific steps:
step 201, the mobile phone receives a network search instruction.
In some embodiments, when the terminal device moves to an operator network that subscribes to a roaming agreement, it is necessary to enable the terminal to perform a network entry procedure in a roaming scenario through network search.
Step 202, network searching is carried out according to the network searching instruction to obtain the mobile country code.
In some embodiments, the network type of the network search is a public land mobile network for which registration has been completed. Generally, when a user moves among regions or countries using a terminal device, a large number of PLMN connection history records registered in the past network use process are stored, and when the user moves to a new region or country, the registered PLMN generates a network search list and uses the PLMN in the list as a network connection priority option for the user to select.
Step 203, the mobile phone sends an acquisition instruction for opening the roaming service.
In some embodiments, when the user opens the roaming service to the operator, an obtaining instruction for opening the roaming service may be sent to the operator having signed the roaming agreement, where the sending form of the instruction may be sending the obtaining instruction through a short message or a mail, or sending the obtaining instruction through a telephone consultation or through terminal application chat software.
And step 204, receiving the roaming service information sent by the operator.
In some embodiments, according to the "the mobile phone sends the obtaining instruction of opening the roaming service" in step 203, the mobile phone receives the roaming service information sent by the roaming agreement operator to the mobile phone by short message, wherein the content of the short message includes the information of the public land mobile network, the radio access technology and the frequency band supported by the terminal of the roaming agreement operator in the roaming service information.
Step 205, determine whether the mobile country code belongs to the country of the operator with the roaming agreement.
In some embodiments, the MCC is in one-to-one correspondence with the PLMN, so that it can be determined whether there is a match between the MCC currently searched for a network and the MCC of the operator network with which the current location has subscribed.
And step 206, stopping network search, and connecting the target public land mobile network according to a preset network information set.
In some embodiments, if the mobile country code belongs to a country in which a roaming agreement operator has been signed, the search is stopped, because the MCC belongs to a registered PLMN and supports roaming service at the current location, and the MCC is connected to the network according to a preset network information set.
The preset network information set is the roaming service information acquired in step 204, and includes information of the public land mobile network, the radio access technology, and the frequency band supported by the terminal of the operator having signed the roaming agreement.
In some embodiments, there are two ways to distinguish between connecting to the target public land mobile network according to the preset network information set:
firstly, determining candidate networks according to the network information set, then determining the signal strength of each candidate network supporting roaming service connection, and dividing the network connection priority of each candidate network based on the signal strength; and ranking the public land mobile networks of the operators having subscribed to roaming agreements in the network information set based on the network connection priority.
Secondly, determining candidate networks according to the network information set; then determining the charge height information of each candidate network under the preset charge deduction standard; and arranging the public land mobile network of the operator with the network information set having signed the roaming agreement based on the expense high-low information.
Step 207, searching other networks supporting the roaming service according to each wireless access technology and frequency band information supported by the terminal equipment.
In some embodiments, if the mobile country code does not belong to a country where a roaming agreement operator has been signed, the search is continued based on the network to which the handset itself supports the connection.
As can be seen from the above, the network search method provided in this embodiment may first receive a network search instruction, and perform network search according to the network search instruction to obtain a mobile country code, where the network search instruction indicates to search for a registered public land mobile network; then, sending an acquisition instruction for opening the roaming service, and receiving roaming service information sent by an operator; then, judging whether the mobile country code belongs to the country of the operator with the roaming agreement; if so, stopping network search, and connecting the target public land mobile network according to a preset network information set, wherein the preset network information set comprises the public land mobile network of the operator with the signed roaming agreement, the wireless access technology and the frequency band information supported by the terminal. The embodiment aims to acquire the roaming service message through the short message, optimize the process of signing the roaming agreement operator on registration, select the network from the operator signing the roaming agreement for connection, reduce unnecessary network search and improve the network searching rate.
