Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the method and system for mobile terminal joint attachment, the storage medium and the mobile terminal of the present invention are described in further detail below with reference to the accompanying drawings and the detailed description.
Example 1
The embodiment provides a method for jointly attaching a mobile terminal, as shown in fig. 1, including:
step S1: the MME constructs an association table according to the overlapping condition of the coverage areas of the TAI and the LAIs in the jurisdiction thereof; the association table includes the TAI, a plurality of LAIs, and a one-to-one correspondence relationship between the TAI and the coverage overlap area of each LAI.
Step S2: the MME receives a connection request message sent by the mobile terminal through the 4G multimode card; the connection request message includes current location information of the mobile terminal.
Step S3: and the MME determines the LAI corresponding to the current position of the mobile terminal according to the current position information and the association table of the mobile terminal, and determines the LAI corresponding to the current position of the mobile terminal as the LAI jointly attached to the mobile terminal.
Step S4: and the MME completes the joint attachment of the mobile terminal according to the LAI of the joint attachment of the mobile terminal.
The joint attachment of the mobile terminal refers to joint attachment of a 4G multi-mode card of the mobile terminal, namely the 4G multi-mode card is attached to a 3G network, and communication is carried out by utilizing the 3G network. After the 4G multi-mode card is attached, the call link of the mobile terminal during the call can be realized. MME, Mobility Management Entity, represents a network node. LAI, Location Area Identity; LAI is a concept of circuit domain in the 2G and 3G era that enables a mobile switching exchange (MSC/server) to search for all cells in the location area of a terminal when paging the terminal, even if the location of the terminal is known. The terminal does not need location update in a location area; when moving across location areas, a location area updating process needs to be initiated so that a network can know the location area of a terminal; meanwhile, in order to keep close contact with the network side, the terminal needs to periodically perform a location area updating process. TAI, Tracking Area Identity, is a concept established by the LTE system for location management of a terminal. When the terminal is in an idle state, the core network can know the tracking area where the terminal is located, and when the terminal in the idle state needs to be paged, paging must be performed in all cells of the tracking area where the terminal is registered. The tracking area is configured at a cell level, a plurality of cells can be configured with the same tracking area, and one cell can only belong to one tracking area.
Through the steps S1-S4, when the TAI and the LAI coverage are not consistent, the LAI derived from the TAI where the mobile terminal is located can be more accurately the LAI where the mobile terminal is actually located, so that the LAI to which the mobile terminal should actually attach can be accurately determined, that is, the cell to which the mobile terminal should actually fall back is accurately determined, and the situation that the mobile terminal that has fallen back performs the location updating process again when there is an incoming call after the combined attachment is avoided, thereby greatly shortening the call setup time of the mobile terminal and improving the user experience.
Example 2

Step S2: the MME receives a connection request message sent by the mobile terminal through the 4G multimode card; the connection request message includes current location information of the mobile terminal.
Step S3: and the MME determines the LAI corresponding to the current position of the mobile terminal according to the current position information and the association table of the mobile terminal, and determines the LAI corresponding to the current position of the mobile terminal as the LAI jointly attached to the mobile terminal.
The method specifically comprises the following steps: as shown in figure 3 of the drawings,
step S31: and judging the coverage range of the TAI and the LAI in the MME region.
If the TAI overlaps with the coverage of one LAI, step S32 is performed: and determining the LAI as the LAI jointly attached by the mobile terminal.
If the TAI overlaps with the coverage of more than two LAIs, step S33 is performed: and calculating the distance between each LAI and the current position of the mobile terminal, selecting the LAI with the minimum distance from the current position of the mobile terminal, and determining the LAI as the LAI jointly attached to the mobile terminal.
Through the steps S31-S33, when the TAI and the LAI coverage are not consistent, the LAI derived from the TAI can be more accurately the LAI where the mobile terminal is actually located, so that the LAI where the mobile terminal should actually be jointly attached can be accurately determined, the mobile terminal is prevented from performing the location updating process again when there is an incoming call after the joint attachment, and the call setup time of the mobile terminal is greatly shortened.
Step S4: and the MME completes the joint attachment of the mobile terminal according to the LAI of the joint attachment of the mobile terminal.
The method specifically comprises the following steps:
step S41: MME sends SGs location update request message to corresponding VLR; the SGs location update request message includes the LAI of the mobile terminal associated with the mobile terminal, the IMSI of the 4G multimode card, the MME information, and the location update type.
Step S42: the VLR stores MME information and creates SGs associations with 4G multimode cards under MME.
Step S43: and the VLR initiates a 4G multi-mode card position updating process to the HLR according to the LAI jointly attached to the mobile terminal and the IMSI of the 4G multi-mode card, and returns confirmation information to the MME after the updating is completed.
Step S44: and the MME sends an attachment completion message to the mobile terminal to complete the joint attachment of the 4G multi-mode card of the mobile terminal.
In this embodiment, the method for jointly attaching a mobile terminal further includes: as shown in fig. 2, step S5: and the MME sends a mobile terminal falling cell indication to the eNB.
Step S6: and the eNB sends the configured LAI jointly attached to the mobile terminal.
Step S7: the mobile terminal falls back to the cell corresponding to the LAI to which it is jointly attached.
