Description

Network access management method and system

Technical field

This document relates to, but is not limited to, the field of wireless communications, and in particular, to a network access management method and system.

Background technique

At present, the trunking communication system is developed to meet the requirements of industry user terminal command and dispatch, etc., which is a dedicated wireless communication system for specific industry applications. The main feature of the trunking communication system is that the public communication system is different from the public radio mobile communication system. In addition to providing the two-way communication function of the mobile phone, the trunking communication system can also provide group (group) calls, full calls, and even support the establishment of call priority levels. It can also perform communication such as priority call and emergency call that is not available in general mobile phones; it can also provide special functions such as dynamic reorganization and virtual private network in the system; these functions are especially suitable for police, national security department-specific communication, airport, customs, Bus transportation, disaster relief and other command and dispatch needs, therefore, the trunking communication system has a wide range of applications in government departments, public safety, emergency telecommunications, electric power, civil aviation, petrochemical, military and enterprise, etc. It is a multi-purpose, high-performance The wireless communication system and the formation of a dedicated communication network independent of the public mobile communication network throughout the world.

With the increasing shortage of spectrum resources, the voice of the public network cluster is increasing. The 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 terminals to continue talking in critical business situations, 3GPP has proposed the need for a unified public access-based unified land-based wireless access network operation (IOPS, Isolated E-UTRAN Operation for Public Safety). The so-called IOPS means that the evolved base station (eNB) or the evolved base station (Nomadic eNB, NeNB) can provide a certain level of reliability for the cluster user terminal in the event that the loop is interrupted or the loop fails and the signaling and data cannot be transmitted normally. The ability to communicate securely.

At the time of the disaster, such as earthquakes, fires, etc., the communication equipment is destroyed, the user cannot communicate normally, and the IOPS network is temporarily set up due to limited network coverage (by one or several (N) eNB groups) In this case, the user is likely to leave the coverage area and cause the dropped calls, especially because the original road facilities are destroyed due to the occurrence of disasters, which leads to complicated and varied roads, which may cause repeated and repeated coverage and cause ping-pong effect. . This not only causes the terminal to access the network to operate and dropped calls frequently, but also the network can not provide effective services for users. In order to avoid such a situation that both occupy valuable communication resources and ensure normal communication of the user, a mechanism is needed to enable the network side (the base station, if there is a local core network, the MME, the HSS, etc.) or the terminal. The above behavior is found and the terminal is prevented from accessing the network again frequently. There is no such mechanism in the prior art.

Embodiments of the invention

Temporarily set up an IOPS network, due to limited network coverage (composed of one or several (N) eNBs), Users are more likely to leave their coverage and cause dropped calls. In particular, since the original road facilities are destroyed due to the occurrence of disasters, the roads are complicated and variable, which may cause the user to repeatedly enter and exit the coverage area and cause the ping-pong effect.

Embodiments of the present invention provide a network access management method and system.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

First, the first embodiment of the present invention will be described.

The embodiment of the present invention provides a network access management method, and the network side device is used as an eNB or an NeNB as an example for description. The terminal access is monitored and blocked by the (N)eNB. The application environment is shown in Figure 1. User A is the user of cell cell 1.

The IOPS network architecture may allow some of the functions of the core network to be completed by the (N)eNB, in which case the (N)eNB may initiate resource release to attach the Detach process.

As shown in FIG. 2, the process of the network access management method provided by the embodiment of the present invention includes:

Step 201: The (N)eNB monitors the terminal.

Step 202: When the terminal A in the (N) eNB coverage area (in units of cells) leaves the cell (determining whether to leave the coverage by using a positioning technology, etc.), triggering the first timer Timer1 to be started, setting the first time Is T _LN , N is an integer greater than or equal to 1.

Step 203: Detect whether the terminal returns to the cell within the T _LN time.

Step 204: If the time exceeds the T _LN terminal A has not returned to the cell, the (N)eNB is triggered to initiate the de-attach Detach process to release its resources, as shown in FIG. 3 .

Step 205: If the terminal A returns to the cell in the T _LN time, the counter is recorded once, and when the number of times of the counter is less than the preset limit access threshold, step 206 is performed; when the value of the counter reaches the preset When the access threshold is restricted, step 207 is performed.

Step 206: Restart the first timer according to the first time, and set the first time to be T _L(N+1). After the terminal A returns to the cell, during the first timing time T _L(N+1) If the terminal A does not leave the cell, the first timer is closed, and the process ends.

If the terminal leaves the cell within the first timing time T _L(N+1) , N is incremented by 1, and the process returns to step 201.

Step 207: The (N)eNB triggers the release of the user resource, and the UE ID (such as the Globally Unique Temporary UE Identity) is classified into the blacklist of the user blacklist of the cell, and starts the second timer. The set time is the second time T _c . A terminal is not allowed to access in the T _c.

(N) The eNB rejects the terminal access procedure. As shown in FIG. 4, the UE sends an RRC Connection Request to the EUTRAN. When it is determined that the UE exists in the blacklist, the UE feeds back the RRC Connection Reject message (RRC Connection). Reject), rejecting the UE access.

Or, after the (N)eNB establishes an RRC connection with the terminal, the terminal matches the blacklist of each cell in the (N)eNB, and when the terminal is in the blacklist of any cell, the ( The NeNB releases the RRC connection, and optionally sends an RRC Connection Release message to the UE.

Step 208, the terminal A exceeds T _c will be removed from the blacklist again allowed access to the terminal A, to avoid the user repeatedly plays the role out of the cell.

In the above embodiment, the first time each time the first timer is set may be the same or different.

In the embodiment of the present invention, the number of times the cell is left (N) eNB is recorded as a record value for triggering and judging, that is, the terminal leaves the cell as a performance of the terminal access state change.

(N) The eNB may also signal the UE to let the UE classify the identity (ID, such as PCI and/or ECGI, etc.) of the cell into the blacklist maintained by itself, and the UE will not attempt to access the cell until then. The cell ID removes its blacklist. As shown in FIG. 5, the (N)eNB sends a blacklist request to the UE, requesting the UE to add the cell to the blacklist, and the UE returns to the (N)eNB after successfully adding the cell to its own blacklist. Black List Update Complete message.

Next, a second embodiment of the present invention will be described.

Step 601: When the terminal A in the coverage area of the (N) eNB (in units of cells) leaves the cell (determining whether to leave the cell coverage by using a positioning technology, etc.), the UE triggers the start of the first timer Timer1, and sets the first One time is T _LN , and N is an integer greater than or equal to 1.

Step 602: Detect whether the UE returns to the cell within the T _LN time.

Step 603: If the time exceeds T _LN and the UE has not returned to the cell, triggering the UE to initiate the de-attach Detach process to release its resources, and may initiate a de-attach Detach process to the (N)eNB, as shown in FIG. 7; The de-attach Detach process is initiated to the MME, as shown in FIG.

Step 604: If the UE returns to the cell within the T _LN time, the counter is recorded once, and when the number of times of the counter is less than the preset limit access threshold, step 605 is performed; when the value of the counter reaches the preset limit When the threshold is accessed, step 606 is performed.

Step 605: Start the first timer, and set the time to be T _L(N+1) ; if the UE does not leave the cell in T _L(N+1) , the first timer is closed, and the process ends.

If the UE leaves the cell in T _L(N+1) , N increases by 1, and returns to step 601.

Step 606: The UE triggers the de-attach Detach process to release the user resource and classifies the cell ID (such as PCI and ECGI, etc.) in the coverage range into the blacklist black list, and starts the second timer, and the set time is Two times T _c . T _c in the UE is not allowed to access the cell.

Step 607, after the cell than T _c UE ID may be removed from the blacklist again allowed access to the cell, to avoid the user repeatedly plays the role out of the cell.

Step 1002: Detect whether the terminal returns to the cell within the T _LN time.

Step 1003: If the time exceeds the T _LN terminal and has not returned to the cell, the MME is triggered to initiate the de-attach Detach process to release its resources, as shown in FIG.

Step 1004: If the terminal returns to the cell within the T _LN time, the counter record is started once. When the number of times the counter is recorded is less than the preset limit access threshold, step 1005 is performed; when the value of the counter reaches the preset limit. When the threshold is accessed, step 1006 is performed.

Step 1005: Start a first timer, and set the time to T _L(N+1) .

If the terminal does not leave the cell within T _{L (N+1)} , the first timer is closed, and the process ends.

If the terminal leaves the cell within T _{L (N+1)} , N is incremented by 1, and the process returns to step 1001.

Step 1006: The MME triggers the de-attach Detach process to release the user resource, and the identifier (UE ID, such as GUTI, etc.) of the terminal is classified into the blacklist black list of the cell, and the second timer is started, and the second time is set. T _c . T _c in the terminal is not allowed to access the cell.
