Description

Network connection processing method and device

Technical field

The present application relates to, but is not limited to, the field of communications, and in particular, to a network connection processing method and apparatus.

Background technique

At present, the trunking communication system is developed to meet the needs of industry users' command and dispatch, etc. It is a dedicated wireless communication system for specific industry applications. The main feature of the trunking communication system different from the public radio mobile communication system is that, in addition to providing the two-way calling function of the mobile phone, it can also provide group (group) calls, full calls, and even establish call priority levels in the system, and can perform Priority call, emergency call, etc., which are not available in general mobile phones; special functions such as dynamic reorganization and virtual private network in the system are also provided. These features are especially suitable for police, national security department-specific communications, and command and dispatch needs for airports, customs, public transportation, disaster relief, etc. Therefore, the trunking communication system is in government departments, public safety, emergency telecommunications, electric power, civil aviation, petrochemical, military and It has a wide range of applications in enterprises and other fields. It is a versatile and high-performance wireless communication system, and has formed a dedicated communication network independent of the public mobile communication network around the world.

As spectrum resources become increasingly scarce, calls for public network clusters are growing. Public network cluster refers to the development of specific trunking communication services based on the existing public mobile communication network.

In order to ensure the ability of cluster user equipment to continue to communicate in critical business situations, the 3rd Generation Partnership Project (3GPP) proposes an isolated E-UTRAN model for serving public safety (Isolated). E-UTRAN Operation, abbreviated as IOPS) mode, the so-called IOPS mode refers to (N)eNB ((Nomadic) evolved Node B, (free state) evolved Node B) (or a group of (N) eNBs) interrupted in the loop Or if the loop fails and the signaling and data cannot be transmitted normally, the cluster user can still provide a certain level of communication capability. After the IOPS network detects the recovery of the macro network loop, the user equipment (User Equipment, UE for short) in the IOPS network should return to the macro network as soon as possible in order to get better service and reduce the cost incurred by starting the local network.

The IOPS network has its particularity, which is generally established in the event of a disaster (such as earthquakes, fires, etc.). If the connected state UE suddenly releases the Radio Resource Control (RRC) connection during the network transition, the communication is caused. Interrupts are likely to cause some important communications and even life-safe communications to be interrupted, which is undesirable for users.

Embodiment 3

13 is a schematic diagram of a base station leaving an IOPS network according to an embodiment of the present invention. As shown in FIG. 13, a base station (N) eNB2 in an IOPS network detects that a loop of a macro EPC is restored to a loop-restricted state (eg, can be reliably transmitted). Signaling, limited transmission of data), (N) eNB2 intends to disconnect from the IOPS network into a loop-limited macro network.

(N) eNB2 detects that the macro network loop is restored to the restricted loop, broadcasts the macro network PLMN ID and the time T1 that the cell under its jurisdiction is about to be closed, and starts timer1, stops broadcasting its IOPS PLMN ID, and sends a paging message to notify the UE system to broadcast the message change. ;

(N) The UE of the cell under the jurisdiction of the eNB2 receives the systemInfoModification in the paging message to learn the system information change, and starts monitoring the new system information in the next modification period.

The UE reads the macro PLMN ID to trigger a terminal alarm (the terminal sends an alarm sound or a red warning light or a voice broadcast), and indicates that the cell under the jurisdiction of the (N)eNB2 is about to be turned off after T1;

If the user (user) predicts that the time when the important information is transmitted is Tf, if Tf>T1, the estimated time Tf at which the communication ends is sent to the (N)eNB2 by triggering the terminal (key, screen, or even combining voice, etc.) Otherwise, enter the idle state after ending the call within its estimated time.

(N) The eNB2 receives the estimated time information sent by multiple UEs and sends it to the OAM. The OAM determines the final shutdown time T2 and sends it to each base station and the local EPC. The local EPC and the (N)eNB2 start the timer. Timer2, (N) eNB2 broadcast and/or dedicated signaling (such as paging message) informs the UE of its final shutdown time T2, and the user should issue important information as much as possible during this time.

When the timer timer2 expires, the (N)eNB2 is triggered to release the RRC connection and release the S1 connection with the local EPC.

Step S1402, (N) eNB2 detects that the macro network loop is restored to a restricted loop;

Step S1404, (N) the cell under the jurisdiction of the eNB2 stops broadcasting the IOPS PLMMN ID, starts broadcasting the macro PLMN ID and the upcoming cell closing time T1, and starts the timer timer 1;

Step S1406: The system broadcast message changes to trigger the connected state UE to listen to the system broadcast message.

Step S1408, it is determined whether the UE reads the macro PLMN ID, if the determination result is no, step S1406 is performed, and if the determination result is yes, step S1410 is performed;

Step S1410, triggering the terminal alarm and indicating that the current cell is closed after T1;

Step S1412, the user (User) estimates the call end time Tf, determines whether Tf>T1 is established, if not, step S1414 is performed, and if it is established, step S1416 is performed;

Step S1414, ending the call after Tf, the UE enters the idle state, and reselects the cell under the macro PLMN ID;

Step S1416, triggering the terminal to send its estimated time Tf to (N)eNB2;

Step S1418, (N) eNB2 sends the estimated time information to the OAM, and the OAM negotiates with the local EPC (N) the cell closing time T2 of the eNB2, and notifies the (N)eNB2 to close the time T2, and synchronizes the start timer timer 2;

Step S1420, (N) eNB2 broadcasts and/or dedicated signaling to notify the UE to close the time T2;

Step S1422, when it is determined whether the timer timer 2 is up, if the determination result is no, step S1420 is performed, and if the determination result is YES, step S1424 is performed;

Step S1424, (N) eNB2 releases the RRC connection and the local EPC S1 connection;

In step S1426, the UE enters the idle state and reselects the cell under the macro PLMN ID.
