Description

Closed member group access control method, device and system

The present invention relates to access control technologies in the field of mobile communications, and in particular, to a closed member group (CSG) access control method, apparatus and system. Background technique

With the development of wireless multimedia services, in order to meet the user's demand for higher data rates and improve the spectrum efficiency of the cellular network, 3GPP introduced a low power node (LPN) as a supplement to the macro base station to provide access services for the UE. Generally, the LPN may also be referred to as a small base station, including a home base station (HeNB), a pico base station (pico), a radio remote unit/header (RRU/RRH), a relay node (RN), and the like. In the hotspot deployment scenario, in order to achieve high data rates and spectrum efficiency, a large number of small base stations need to be deployed in the area. However, since the coverage of the small cell under the small base station is small, the probability of a handover failure occurs when the medium and high speed mobile UE passes through the small base station, which affects the UE service continuity. In order to improve the UE mobile performance after the introduction of the small cell, the industry proposes that a base station (eg, a macro base station) guarantees basic coverage, and the UE always maintains an RRC connection with the base station, and the small cell only serves as a transmission node (TP, Transmission Point). ) to provide a higher data rate and meet the user's power saving needs. In this system architecture, the UE maintains a connection with at least two base stations and uses radio resources under two base stations to implement wireless resource aggregation across nodes. This architecture is commonly referred to as a dual connectivity architecture.

The two base stations connected by the UE in the dual connectivity architecture have a certain management control capability, which is usually called a master eNB (MeNB), and the other base station is called a secondary eNB (SeNB). After the UE accesses the MeNB, the dual connection can be implemented through the SeNB adding process. After the SeNB is successfully added, the MeNB can perform a series of management on the SeNB, such as SeNB modification, SeNB deletion, and SeNB modification. However, in the dual connectivity architecture, if the MeNB or SeNB is a HeNB, It is possible that the HeNB and the neighboring base station have no X2 interface scenario, that is, there is no X2 interface between the MeNB and the SeNB, and the SeNB management and the CSG related function in this scenario need to be solved. In the prior art, there is no SeNB management and CSG access control method in the case where there is no X2 interface between the MeNB and the SeNB in the dual connectivity architecture.

This embodiment describes a method for the MME to perform a CSG check in the SeNB adding process. FIG. 3 is a schematic flowchart of the method according to the embodiment, including the following steps:

Step 301: The MeNB acquires the RRM measurement result reported by the UE, and determines, according to the RRM measurement result of the UE, the SeNB to add an SeNB adding procedure.

In this embodiment, the SeNB may be an HeNB.

The RRM measurement report may include: a CSG identity status of the UE in a CSG or a hybrid cell of the SeNB, or a PLMN ID list of the UE being a member in a CSG/mixed cell of the SeNB.

In this embodiment, the deployment of the MeNB and the SeNB can be classified into the following cases:

1) MeNB is a macro eNB, and SeNB is a hybrid or closed mode HeNB;

2) Both the MeNB and the SeNB are hybrid or closed mode HeNBs, and the CSG IDs of the MeNB and the SeNB are different;

3) Both the MeNB and the SeNB are hybrid or closed mode HeNBs, and the MSG and SeNB have the same CSG ID.

In case 1) or 2), the MME needs to perform CSG access control or membership verification before obtaining the CSG check result;

In case 3), CSG access control or membership authentication is not required to be performed by the MME, but the SeNB is accessed by the UE in the same CSG identity state of the CSG cell of the MeNB.

Step 302: The MeNB sends a message for the SeNB addition request to the MME through the S1 interface, where the message includes the CSG ID, the access mode, the PLMN ID, the CSG identity status, the base station ID corresponding to the CSG ID, and the E-RAB information. Source identification information, target identification information.

Since there is no X2 interface between the MeNB and the SeNB, the MeNB sends a message for the SeNB addition request to the MME through the S1 interface. The CSG ID and the access mode are the CSG ID and the access mode of the SeNB cell, and the PLMN ID is the PLMN ID of the SeNB cell selected by the MeNB for the UE.

The CSG identity status is the default identity status or the identity status reported by the UE or the same identity status as the UE in the MeNB cell. The E-RAB information is the E-AB information of the UE to be transferred to the SeNB. The source identification information and the target identification information are the eNB ID and/or TAI information of the MeNB and the SeNB, respectively.

Step 303: The MME receives the message for the SeNB addition request, obtains the CSG subscription information of the UE from the HSS according to the CSG ID in the message for the SeNB addition request, and adds the CSG ID in the request message to the SeNB. CSG inspection, the results of CSG inspection.

The CSG check may include: CSG access control or membership authentication, to determine whether the UE can access the CSG cell of the SeNB, or access the mixed cell of the SeNB as a member or non-member.

Optionally, the MME may also perform verification of the CSG ID and the access mode to verify the CSG ID and/or access mode validity of the SeNB's CSG/hybrid cell.

If the message for the SeNB addition request received by the MME includes E-RAB information, the MME may use the CSG ID and the corresponding E-RAB information for subsequent charging purposes.

Optionally, the MME determines that both the MeNB and the SeNB are HeNBs, and the CSG IDs of the MeNB and the SeNB are the same, and the MME does not perform the CSG check.

If the MME receives the CSG identifier in the message for the SeNB addition request, but does not include the access mode or the included access mode is closed, the MME performs a CSG check to determine whether the UE is allowed to access the CSG ID identifier. CSG cell.

If the received message for the SeNB addition request includes the CSG identity and the access mode, and the access mode is mixed, the MME performs a CSG check to determine that the UE is identified by the member or non-member identity as the CSG ID. Mixed cell of the SeNB. Step 304: If the CSG check result is that the UE can access the SeNB cell, the MME includes the CSG check result in a message for the SeNB addition request, and sends the message for the SeNB add request to SeNB.

Steps 305a-305b: The SeNB determines whether to accept the SeNB addition request, for example, according to the CSG check result received from the MME and the current load situation, if yes, according to the SeNB adding the request E-RAB information for resource pre-request And generating an SeNB addition request acknowledgement message according to the SeNB addition request, and sending the SeNB to add a request acknowledgement message to the MeNB.

The SeNB add command may include air interface radio resource configuration information. Also included: source and destination identification information, such as eNB ID and / or TAI information. Since there is no X2 interface between the SeNB and the MeNB, the SeNB sends the message to the MME first, and then the MME sends the message to the MeNB.

Step 306 a-306b: After receiving the SeNB add request acknowledgement message, the MeNB instructs the UE to perform cell synchronization and random access with the SeNB through C-specific signaling, and performs radio resource reconfiguration.

After receiving the reconfiguration complete message of the UE, the MeNB sends a SeNB reconfiguration complete message to the Se muscle.

Since there is no X2 interface between the SeNB and the MeNB, the MeNB sends the message to the MME first, and then the MME sends the message to the SeNB.

Step 307: The MeNB sends an E-RAB modification indication message to the MME, where the E-RAB information to be transferred to the SeNB, for example, GTP tunnel information, etc., is included.

Step 308: The MME interacts with the SGW to transfer the S1-U tunnel of part of the E-RAB of the UE, and then replies to the MeNB with an E-RAB modification confirmation message.

It should be noted that the E-RAB modification indication message may be sent by the SeNB to the MME in step 307, instead of being sent by the MeNB to the MME, and the MME returns an E-RAB tampering confirmation message to the SeNB after receiving the message. Method embodiment 4

This embodiment describes a method for performing CSG check in the SeNB adding process when the UE is not a CSG cell member of the SeNB. FIG. 4 is a schematic flowchart of the method according to the embodiment, including the following steps:

Step 401: The MeNB acquires the RRM measurement result reported by the UE, and determines, according to the RRM measurement result of the UE, the SeNB to add an SeNB adding procedure.

In this embodiment, the SeNB is a closed mode HeNB, and the RRM measurement report of the UE includes a CSG identity status of the CSG cell of the SeNB, or a list of PLMN IDs that are reported by the UE as a member in the CSG cell of the SeNB.

In this embodiment, the MeNB is a macro eNB or a HeNB (the CSG ID is different from the SeNB), so the CSG access control needs to be performed by the MME to determine whether the UE can access the Se muscle.

Step 402: The MeNB sends a message for the SeNB addition request to the MME through the S1 interface, where the message includes the CSG ID, the access mode access mode, the PLMN ID, the CSG identity status, and the identifier of the base station corresponding to the CSG ID, E- RAB information, source identification information, target identification information.

The CSG ID and the access mode are the CSG identifier and the access mode of the SeNB cell, and the PLMN ID is the PLMN ID of the SeNB cell that the UE currently serves the PLMN ID or the MeNB is selected by the UE.

The CSG identity status is the default identity status or the identity status reported by the UE. The E-RAB information is the E-RAB information of the UE to be transferred to the SeNB.

The source identification information and the target identification information are the eNB ID and/or TAI information of the MeNB and the SeNB, respectively.

Step 403: The message that is sent by the MME for the SeNB addition request, when the message for the SeNB addition request includes only the CSG ID information, does not include the access mode or includes In the closed access mode, the MME performs CSG check, that is, CSG access control, according to the CSG subscription information of the UE obtained from the HSS, to determine whether the UE can access the CSG cell of the SeNB.

Optionally, the MME further performs verification of the CSG ID and/or the access mode to verify the CSG ID and access mode validity of the CSG/hybrid cell of the SeNB.

Step 404: The MME determines, by using the CSG check, that the UE is not a member of the CSG cell of the SeNB, and obtains a CSG check result that is not allowed to access the SeNB cell, and sends the CSG check result to the MeNB by using an S1 message, for example, the SeNB adds a failure message.

The result of the CSG check is that no access indication or non-membership indication or appropriate cause value is allowed. Method embodiment 5

This embodiment describes a method for the MeNB and the SeNB to complete the SeNB tampering process through the MME. FIG. 5 is a schematic flowchart of the method according to the embodiment, which includes the following steps:

Step 501: The MeNB and the SeNB are the macro eNB or the HeNB, and the MeNB determines that the SeNB is required to modify the radio resource configuration of the E-AB. The MeNB sends an SeNB modification request message to the MME through the S1 interface, because the MeNB has no X2 interface between the MeNB and the SeNB. It may contain E-RAB information, source identification information, and target identification information. The E-RAB information is the E-RAB information of the UE of the SeNB to be modified. The source identification information and the target identification information are the eNB ID and/or TAI information of the MeNB and the SeNB, respectively.

Step 502: After receiving the SeNB modification request message, the MME sends a SeNB modification request message to the SeNB indicated by the target identification information.

Steps 503a-503b, if the SeNB accepts the SeNB modification request, send an SeNB modify request acknowledgement message to the MeNB, where the message may include the modified air interface radio resource configuration letter. Interest. The message also includes source and destination identification information, such as eNB ID and/or TAI information. Since there is no X2 interface between the SeNB and the MeNB, the SeNB sends the message to the MME first, and then the MME sends it to the Me muscle.

Step 504 a-504 b: After receiving the message, the MeNB instructs the UE to perform radio resource reconfiguration through RRC dedicated signaling. After receiving the reconfiguration complete message sent by the UE, the MeNB sends an SeNB reconfiguration complete message to the SeNB. Since there is no X2 interface between the SeNB and the MeNB, the MeNB sends the message to the MME first, and then the MME sends the message to the SeNB.

It should be noted that the SeNB modification process initiated by the MeNB is described in this embodiment. The SeNB modification process may also be initiated by the SeNB. If there is no X2 interface between the MeNB and the SeNB, the interaction message between the MeNB and the SeNB also needs to pass through the MME. Forward. Method Embodiment 6

This embodiment describes a method for the MeNB and the SeNB to complete the SeNB release process by using the MME. FIG. 6 is a schematic flowchart of the method according to the embodiment, which includes the following steps:

Step 601: The MeNB and the SeNB are the macro eNB or the HeNB, and the MeNB determines to perform the SeNB release procedure, for example, because the UE moves out of the coverage of the SeNB or due to load balancing. The MeNB sends an SeNB release request message to the MME through the S1 interface, and the message may include source identification information and target identification information. The source identification information and the target identification information are eNB ID and/or TAI information of the MeNB and the SeNB, respectively.

Step 602: After receiving the SeNB release request message, the MME releases the SeNB release request message to the SeNB indicated by the target identifier information.

Step 603: After receiving the message, the MeNB instructs the UE to perform radio resource reconfiguration through RRC dedicated signaling. After the reconfiguration is completed, for the dual connectivity user plane architecture 1A, the MeNB sends an E-RAB modification indication message to the MME for S1 user plane path update, which includes E-RAB information to be transferred to the SeNB, for example, GTP tunnel information, etc. . Step 604: The MME interacts with the SGW to transfer the S1-U tunnel of the partial E-RAB of the UE, and then replies to the MeNB with an E-RAB modification confirmation message.

It should be noted that, in this embodiment, the SeNB release process initiated by the MeNB is described, and the SeNB release process may also be initiated by the SeNB. If there is no X2 interface between the MeNB and the SeNB, the interaction message between the MeNB and the SeNB also needs to pass through the MME. Forward.

It should be noted that the embodiments provided by the present invention are all based on the dual connectivity architecture. As shown in FIG. 7, the two base stations connected by the UE have a certain management control capability, which is usually called a primary base station (MeNB), and the other base station is A sub-base station, after the UE accesses the MeNB, the dual-connection can be implemented through the SeNB adding procedure. After the SeNB is successfully added, the SeNB can perform a series of management, such as SeNB modification, SeNB deletion, and SeNB modification.

There are three possible architectures for the user plane in the dual connectivity architecture. As shown in Figure 8, the SI user plane interface (S1-U) in the architecture 1 terminates at the MeNB and the SeNB; in the architecture option 2, the S1-U terminates at the MeNB. The RAN side has no bearer separation. In the architecture option 3, the S1-U terminates at the MeNB, and the RAN side has a bearer separation. For example, after the downlink data in the EPS bearer arrives at the MeNB, part of the data in one bearer can be separated into the SeNB, and then sent by the SeNB. Give the UE. According to the user plane protocol stack architecture of the SeNB, the above three architectures can be further subdivided.

Dual connectivity can use the 1A architecture in the option optionl, or the 3C architecture in the architecture option3. As shown in FIG. 9, the architecture 1A uses the architecture optionl, and the user plane protocol stack on the SeNB has an independent Packet Data Convergence Protocol (PDCP) and the following protocol layers, and no bearer separation. The architecture 3C is shown in Figure 10, that is, the architecture option3 is used, and the user plane protocol stack on the SeNB has an independent Radio Link Control Protocol (RLC) and the following protocol layers.

The UE moves from one SeNB to another SeNB coverage scenario, and the MeNB performs a SeNB change process for the UE. From the perspective of message interaction between the MeNB and the SeNB, the process can be regarded as a superposition of the SeNB addition and the SeNB deletion process, if the MeNB And SeNB If there is no X2 interface between the two, the message exchange between the MeNB and the SeNB is forwarded by the MME.
