Description
Technical Field
The invention relates to an international roaming technology in the field of mobile communication, in particular to a processing method, a device and a terminal for international roaming in a network configuration peer-to-peer public land mobile network (EPLMN) scene.
Background
When the LTE terminal roams and selects a Network across borders, because Public Land Mobile Networks (PLMNs) IDs of networks covered on both sides of the border are different and are not associated with each other, as an original resident Network signal is gradually weakened, the terminal finally leaves the original resident Network, and then searches for a resident Network again for residence. This off-line-re-search process can result in the user being in an "out-of-service" state for a long period of time, and the re-camped network cannot be specified by the original operator.
In order to improve the network selection experience of a user during cross-border roaming and shorten the 'no service' time of a terminal, part of operators deploy EPLMNs of roaming area cooperation operators in border areas. However, at this time (in the network configuration EPLMN scenario), when the terminal performs cross-border roaming, the following problems may occur in the aspects of status display, protocol stack opening, and the like:
1) when the terminal roams from a continental operator to other overseas operators in a reselection/redirection mode, the terminal status column does not display the roaming state 'R', thereby misleading the user to think that the terminal still does not roam at the moment. Because the user does not know that the roaming charging is started, more roaming charges can be generated, and the user experience is influenced;
2) part of customized terminals (supporting TD-LTE, TD-SCDMA and GSM three modes in domestic scenes; supporting TD-LTE, FDD LTE, WCDMA, GSM four modes in an international roaming scene) when reselecting/redirecting to other overseas operators, mode switching does not occur, and the terminal only supports domestic standard and frequency band, so that the terminal cannot normally use non-domestic standard and non-domestic frequency band of a roaming area network.

The embodiment of the invention also provides a terminal, which comprises the device.
In order to facilitate understanding of the solution of the embodiment of the present invention, a method for an existing operator to deploy an EPLMN of a roaming regional partner operator in a border area is briefly described below. The specific implementation method comprises the following steps:
and starting an EPLMN function in a network Mobility Management Entity (MME) of the border region of the country, adding the PLMN of the cooperative operator into an EPLMN list, and issuing the EPLMN list by taking a Tracking Area (TA) as a unit. When the terminal in the TA roams across the border, the terminal can be reselected/redirected to the operator network of the adjacent country/region, so that the traditional offline-re-searching mechanism is replaced, and the roaming network selection time is greatly shortened.
The present invention is described in detail below with reference to specific application scenarios.
Scene one
The terminal resides in a cell of a local operator in China, moves to a Public Land Mobile Network (PLMN) of an overseas cooperative operator in a border area, and is a TA area of the EPLMN. And the terminal acquires and stores the EPLMN list issued by the network side in the process. The terminal keeps the power-on state to move outwards, and the signal intensity of the original operator is gradually weakened.
The application scene corresponds to the condition that the terminal is in an idle state.
And when the network environment meets the condition of reselecting the adjacent cell of the EPLMN, the terminal performs reselection judgment and completes the residence in the target cell. When the residing is successful, the terminal reads the system broadcast message, and then finds that the MCC of the PLMN ID of the residing target cell is changed from domestic (for example, China: 460) to foreign (for example, hong Kong: 454). There are two processing methods for the terminal:
the method comprises the following steps:
the terminal is immediately switched into a roaming mode according to the change of the MCC, and a terminal status bar displays a roaming indication mark R;
the terminal only changes the mode and frequency band supported by the terminal into the mode and frequency band corresponding to the overseas network in the mode conversion process, does not search for the network again, still resides in the target cell, and initiates a Tracking Area Update request (Tracking Area Update request) to the target cell after the conversion; since the original cell and the neighbor cell (target cell) of the EPLMN belong to different core networks, the request is rejected by Cause 9: tracking Area Update reject;
and then the terminal initiates an Attach request to the target cell and successfully attaches after receiving an Attach message returned by the target cell.
The method 2 comprises the following steps:
the terminal initiates a Tracking Area Update request and an Attach request to a target cell, and receives an Attach accept message returned by the target cell;
after successful attachment, as no data transmission exists, the network side issues an RRC Connection Release message to Release RRC Connection, the terminal receives the message and enters an idle state, then mode conversion is carried out, the terminal only changes the mode and the frequency band supported by the terminal into the mode and the frequency band corresponding to the overseas network in the mode conversion process, network searching is not carried out again, and the terminal still resides in a target cell;
the terminal status bar displays a roaming indicator "R".
Scene two
The terminal resides in a cell of a local operator in China, moves to a Public Land Mobile Network (PLMN) of an overseas cooperative operator in a border area, and is a TA area of the EPLMN. And the terminal acquires and stores the EPLMN list issued by the network side in the process. The terminal keeps the power-on state to move outwards, and the signal intensity of the original operator is gradually weakened.
The application scenario corresponds to the situation that the terminal is in a connected state.
And when the network environment meets the requirement of redirection to the adjacent cell of the EPLMN, the terminal receives the redirection command and completes the residence in the target cell. When the camping is successful, the terminal reads the system broadcast message, and then finds that the MCC of the PLMN ID of the camping cell is changed from domestic (for example, China: 460) to foreign (for example, hong Kong: 454). There are two processing methods that follow:
the method comprises the following steps:
the terminal is immediately switched into a roaming mode according to the change of the MCC, a terminal status bar displays a roaming indication mark R, the terminal only changes the mode and the frequency band supported by the terminal into the mode and the frequency band corresponding to the overseas network in the mode switching process, network searching is not carried out again, and the terminal still resides in a target cell;
after conversion, the terminal initiates a Tracking Area Update request to the adjacent cell, and because the original cell and the adjacent cell of the EPLMN belong to different core networks, the request is rejected by the Cause 9: tracking Area update project;
and then the terminal initiates an Attach request to the target cell, receives an Attach message returned by the target cell and successfully attaches the Attach message.
The method 2 comprises the following steps:
the terminal initiates a Tracking Area Update request and an Attach request to a target cell and receives an Attach accept message;
after the terminal finishes the data service, the network side issues an RRC Connection Release message to Release the RRC Connection, and the terminal enters an idle state after receiving the message;
mode switching is then performed according to a previous MCC change, and the terminal status bar displays a roaming indicator "R".
