The following are detailed below. The numbers in the following examples are not intended to limit the order of preference of the examples.
In this embodiment, a network side handover method is provided, as shown in fig. 1, a specific flow of the network side handover method may be as follows:
110. the method comprises the steps of obtaining a network identification of a current network side connected with a terminal and mapping relation information, wherein the mapping relation information comprises a mapping relation between the network identification and a frequency band of a target network side, and the target network side is a next generation network side corresponding to the current network side.
The terminal is a user terminal, such as a mobile phone, a tablet computer, a smart watch, a smart terminal, and the like.
The current network side is a network side where the terminal is currently connected, such as a 2G network side, a 3G network side, a 4G network side, a 5G network side, and the like.
The Network identifier is a Network side identifier, that is, a Public Land Mobile Network (PLMN) and is composed of a Mobile Country Code (MCC) and a Mobile Network Code (MNC), for example, the PLMN of china Mobile is 46000, 460 is a country code, and 00 is a Mobile Network code.
The target network side is a network side which is connected by the terminal support. For example, one terminal simultaneously supports a 2G network side, a 3G network side, a 4G network side, a 5G network side, and the like, where the network side currently connected to the terminal is the 3G network side, and the target network side is the 4G network side.
The frequency band is used for communication connection with a network side. For example, 46000 (china mobile), the 4G frequency bands supported by the network are 38, 39 and 40 frequency bands; 46001 (china unicom), the 4G frequency bands supported by the network are 3, 40 and 41 frequency bands; 46011 (china telecommunications), the 4G bands supported by the network are the 3, 40 and 41 bands.
In some embodiments, in order to allow for obtaining the network identifier of the current network side, before obtaining the network identifier of the current network side connected to the terminal, the method further includes:
responding to the trigger of network connection, and sending a connection request to the current network side;
receiving connection establishment information returned by the current network side according to the connection request;
and responding to the connection establishment information, and acquiring the network identification of the current network side from the connection establishment information.
The CONNECTION REQUEST is used to REQUEST CONNECTION with the network side, for example, RRC CONNECTION REQUEST sent by the terminal to the current network side.
The CONNECTION establishment information is used to characterize the communication CONNECTION between the terminal and the network side, for example, the current network side returns an RRC CONNECTION SETUP based on the CONNECTION request to the terminal.
For example, after responding to the trigger of the network connection, the terminal triggers a network searching process, selects a mobile network and a 3G module for network searching, and the 3G base starts to search for the 3G network, and if a 3G network side is searched, further receives connection establishment information sent by the 3G network side, where the connection establishment information includes system information and main information (masterinformation block), and obtains a network identifier of the current network side from the main information.
In some embodiments, in order to allow for the triggering of the network connection by the terminal, responding to the triggering of the network connection includes:
and triggering the network connection of the terminal when the terminal is started or the terminal is from the no-signal area to the signal area.
In some embodiments, before acquiring the network identifier of the current network side connected to the terminal, in order to consider that the terminal sends the connection request to the current network side, the method further includes:
responding to the trigger of searching the network, acquiring a network identifier used for searching the network side and a current network type corresponding to the network identifier;
performing network search according to the network identifier and the current network type to obtain a current network side;
receiving system information and main information issued by a current network side;
analyzing cell information from the system information and the main information, wherein the cell information comprises cell selection information;
and determining that the cell corresponding to the current network side meets the preset condition according to the cell selection information, and residing the terminal in the cell so that the terminal can send a connection request to the current network side of the cell.
When the current network type is a search network side, the network side corresponds to a type, for example, a 3G network side, a 4G network side, a 5G network side, and the like.
The system information is system information blocks sent by the front network side.
The main information is a master information block sent by the current network side.
Wherein the cell information is sib 1.
The sib1 message may be roughly divided into cell access related information (cellaccesratedinfo), cell selection information (cellselectedinfo), and band information (freqBandIndicator) of a cell. For example, the terminal pays attention to the cellSelectionInfo, if the terminal wants to successfully camp on a cell, the current cell must satisfy the S criterion, and in the cell selection process, the terminal needs to measure the cell to be selected so as to perform channel quality evaluation and determine whether the cell meets the camping standard. The measurement criterion for cell selection is called S-criterion, and when the channel quality of a certain cell meets the S-criterion, the certain cell can be selected as a camping cell.
For example, the first thing done after the terminal is powered on is to perform a synchronization process on the frequency band supported by the terminal, check whether the frequency band is from a legal operator, once the terminal is successfully synchronized, the terminal will read the master information block and the system information block sent by the current network side, and determine whether the cell can reside by checking the information in the sib 1. And if the condition is met, the terminal successfully resides in the cell. The terminal will then perform RRC connection setup. In the process, random access (random access procedure) is performed, and the current network side knows for the first time that there is a terminal to access itself and provides some temporary resources for the terminal.
In some embodiments, in order to allow for the terminal not to acquire information related to the network again after initiating a communication connection with the network side later, before determining, according to the cell selection information, that a cell corresponding to the current network side satisfies a preset condition, the method further includes:
analyzing a current network identifier from the main information, wherein the current network identifier is a network identifier corresponding to a current network side;
the current network identification is stored.
120. And determining a target frequency band corresponding to the network identifier from the mapping relation information, wherein the target frequency band is a frequency band corresponding to the target network side.
For example, the mapping relationship information includes 46000 (china mobile), and the 4G frequency bands supported by the network are 38, 39, and 40 frequency bands; 46001 (china unicom), the 4G frequency bands supported by the network are 3, 40 and 41 frequency bands; 46011 (china telecommunications), the 4G bands supported by the network are the 3, 40 and 41 bands.
130. And acquiring a terminal frequency band supported by the terminal, wherein the terminal frequency band is the frequency band supported by the terminal.
The terminal frequency band refers to a communication frequency band of the terminal, for example, the terminal may communicate with the network side on the frequency band, and the frequency band supported by the terminal may be:
b1/2/3/4/5/7/8/17/18/19/20/26/28/34/38/39/40/41, etc.
140. And determining the intersection frequency band of the terminal frequency band and the target frequency band to obtain a reported frequency band.
The reporting frequency band is a frequency band sent to the current network side, for example, the target frequency band is a 4G frequency band supported by the national mobile network: 4G frequency bands 38, 39, and 40, the current network side is the 3G network side, that is, the terminal sends the frequency band information including 38, 39, and 40 to the 3G network side.
150. And reporting the reported frequency band to the current network side so that the current network side switches the terminal to be connected with the target network side according to the reported frequency band.
For example, in the 3G call process, when the mobile phone moves from the 3G coverage area to the 4G coverage area, a 3G and 4G switching process may be involved, whether the mobile phone can be switched to the 4G is determined by the 3G network side, and the 3G network side may determine whether to switch to the 4G according to the 4G frequency band supported by the mobile phone, for example, the mobile phone cannot switch to the 4G network if the mobile phone does not support the 4G frequency band of the network, and if the mobile phone supports the 4G frequency band of the network, the mobile phone may switch to the 4G network. How the 3G network side knows the 4G frequency band supported by the mobile phone is that when the 3G network is registered by the mobile phone, the mobile phone sends the supported 4G frequency band to the 3G network.
In some embodiments, in order to consider how to send the reporting band to the current network side, the band reporting unit is configured to:
loading the reported frequency band into a communication protocol identifier in the connection completion information;
and sending connection completion information to the current network side so that the current network side switches the terminal to be connected with the target network side according to the communication protocol identifier and the reported frequency band.
The CONNECTION completion information is communication CONNECTION information fed back by the terminal to the network side, for example, RRC CONNECTION SETUP COMPLETE.
The communication protocol identifier is used to characterize a communication protocol supported by the terminal, for example, an identifier specified by a 3GPP protocol, where the identifier is used for a 4G frequency band supported by the mobile phone, and the 3G network side can know that the identifier is the 4G frequency band supported by the mobile phone after receiving the identifier.
In some embodiments, in order to reduce the number of terminal reports, the number corresponding to the reporting frequency band is less than or equal to the number of terminal reports, and the number of terminal reports is the number corresponding to the maximum frequency band reported by the terminal to the current network side.
For example, the terminal supports the 3GPP 3G TS 25.331R 11.7 protocol version, the 3GPP 3G TS 25.331R 11.7 protocol version supports maximum reporting of 16 frequency bands to the current network side, and the target network side supports only 3 frequency bands, so that the terminal may only send 3 reported frequency bands to the current network side.
As can be seen from the above, in the embodiment of the present application, the network identifier of the current network side connected to the terminal and the mapping relationship information may be obtained, where the mapping relationship information includes a mapping relationship between the network identifier and a frequency band of the target network side, and the target network side is a next-generation network side corresponding to the current network side; determining a target frequency band corresponding to the network identifier from the mapping relation information, wherein the target frequency band is a frequency band corresponding to a target network side; acquiring a terminal frequency band supported by a terminal, wherein the terminal frequency band is the frequency band supported by the terminal; determining an intersection frequency band of the terminal frequency band and the target frequency band to obtain a reported frequency band; and reporting the reported frequency band to the current network side so that the current network side switches the terminal to be connected with the target network side according to the reported frequency band.
In the embodiment of the invention, the terminal can acquire the network identifier of the current network side connected with the terminal, and determine the target network side corresponding to the network identifier and the target frequency band supported by the target network side according to the mapping relation information, the terminal can send the frequency band supported by the target network side to the current network side, namely the reporting frequency band, and the current network side can be switched to the target network side according to the reporting frequency band sent by the terminal, so that the number of the reporting frequency bands sent to the current network side is reduced, meanwhile, the current network side can be switched to the target network side corresponding to the reporting frequency band, and the problem that the current network side cannot receive the target frequency band supported by the target network side is avoided, therefore, the network side which is in communication connection with the user terminal can be switched conveniently.
The method described in the above embodiments is further described in detail below.
In this embodiment, a method in the embodiment of the present application will be described in detail by taking a terminal supporting the 3GPP 3G TS 25.331R 11.7 protocol version as an example.
As shown in fig. 2a and fig. 2b, a specific flow of a network side handover method is as follows:
the method comprises the steps that a terminal is started or a signal area is formed from a no-signal area, a network searching module triggers a network searching process, the network searching module selects a PLMN for searching the network and a corresponding 3G network system, a 3G bottom layer starts to search a 3G network side, if the 3G network side is searched, a system message and a MasterInformationBlock message issued by the 3G network side are further received, the PLMN of a current network is obtained from the MasterInformationBlock message, the current network PLMN is stored by the terminal, and if the cell meets a cell residence standard, the terminal resides in the cell.
And secondly, triggering a terminal upper layer (such as ATTACH and RAU flows) to establish an RRC REQUEST, triggering the terminal to establish RRC signaling CONNECTION with the current network side, initiating an RRC CONNECTION REQUEST message to the 3G network side by the terminal, and responding to the RRC CONNECTION SETUP if the 3G network side receives the RRC CONNECTION REQUEST message of the terminal.
And thirdly, the terminal acquires the PLMN of the current network side from the MasterInformationBlock message, transmits the PLMN to a PLMN of a storage operator and a module for storing the 4G frequency band supported correspondingly, the storage module is matched with the 4G frequency band supported by the 4G network of the storage operator according to the PLMN and the mapping relation information, and the supported 4G frequency band is returned to the RRC module.
Mapping relation information:
the mobile network band selection table comprises a table, wherein the table has two fields, a field 1PLMN is a PLMN of a storage network operator, a field 2 PLMN is a 4G band supported by a 4G network corresponding to the network operator PLMN, and each row of the table indicates the 4G band supported by the network operator PLMN, such as 38, 39 and 40 bands supported by the 4G network of the china mobile 46000.
| PLMN | Network supported 4G frequency band |
| 46000 (China mobile) | 38. 39 and 40 frequency bands |
| 46001 (China Unicom) | 3. 40 and 41 frequency bands |
| 46011 (China telecom) | 3. 40 and 41 frequency bands |
And fourthly, the RRC module acquires the 4G frequency band supported by the current network side, and simultaneously acquires the 4G frequency band shared by the RRC module and the terminal by combining the currently and actually supported 4G frequency band of the terminal, puts the 4G frequency band of the intersection part into an RRC CONNECTION SETUP COMPLETE message, and sends the RRC CONNECTION SETUP COMPLETE message to the 3G network side.
As can be seen from the above, compared with the scheme lower than the 3GPP 3G TS 25.331R 11.7 protocol version, regardless of the 4G frequency band supported by the network side, all the 4G frequency bands supported by the terminal are always reported to the 3G network, and if the supported 4G frequency band is greater than 16 frequency bands, the excess frequency band cannot be reported to the 3G network.
In order to better implement the method, embodiments of the present application further provide a network-side switching device, where the network-side switching device may be specifically integrated in an electronic device, and the electronic device may be a terminal, a server, or the like.
