Problems solved by technology

If the LIPA access control criteria in the scenario where the HeNB supports the LIPA function is still used, the MME will reject all LIPA PDN connection establishment requests under the relay cell, resulting in the failure of LIPA access control for all UEs under the LIPA relay cell

Embodiment 1

[0106] Image 6 It is a schematic flow chart of Embodiment 1 of the access control method of the present invention, and it is a specific implementation method of establishing a LIPA PDN connection through an RN supporting the LIPA function by using UE, such as Image 6 As shown, in this embodiment can be based on image 3 In the architecture shown, the SGW and PGW serving the RN are set separately from the DeNB. The SGW and PGW serving the RN can also be co-located in one entity with the DeNB, and the method flow is similar to this embodiment; for example Image 6 As shown, the method includes the following steps:

[0107] Step 601, during uplink information transmission, UE carries NAS message in RRC message, and the NAS message is used to initiate a PDN connection establishment request, and the NAS message includes the APN of the PDN that UE wants to access.

[0108] Step 602, after receiving the NAS message sent by the UE, the RN encapsulates the NAS message into a Non-A...

Embodiment 2

[0113] This embodiment is a specific implementation method for the MME to judge whether to perform CSG subscription data check according to whether the serving cell of the UE has a CSG ID. The method includes the following steps:

[0114] Step 1. The MME receives the S1 message containing the NAS message sent by the UE. The NAS message is a PDN connection establishment request message. The NAS message includes the APN of the PDN that the UE requests to connect to.

[0115] Step 2: The MME judges whether the APN allows LIPA access; in the user subscription data of the UE, if the value of the LIPA permission flag associated with the APN is "LIPA-only" or "LIPA-conditional", the MME considers that the APN Allow LIPA access; if the value of the LIPA permission flag associated with the APN is "LIPA-prohibited", or the APN has no associated LIPA permission flag, the MME considers that the APN does not allow LIPA access; here, if the APN associated with the LIPA permits The value of ...

Embodiment 3

[0123] This embodiment is a specific implementation method for the MME to perform CSG inspection identification according to the needs of the APN association requested by the UE to determine whether to perform CSG subscription data inspection. The method includes the following steps:

[0124] Step 1, the MME receives the S1 message including the NAS message sent by the UE, the NAS message is a PDN connection establishment request message, and the NAS message includes the APN of the PDN that the UE requests to connect to.

[0125] Step 2: The MME judges whether the APN allows LIPA access; in the user subscription data of the UE, if the value of the LIPA permission flag associated with the APN is "LIPA-only" or "LIPA-conditional", the MME considers that the APN Allow LIPA access; if the value of the LIPA permission flag associated with the APN is "LIPA-prohibited", or the APN has no associated LIPA permission flag, the MME considers that the APN does not allow LIPA access; here, ...

Abstract

The invention discloses an access control method, comprising: a mobile management entity judges whether to check CSG subscription data, and performs LIPA access control according to the judgment result; the invention also provides a mobile management entity. According to the technical scheme of the present invention, the problem of LIPA access control of the UE served by the cell without the CSG ID is avoided, so that the LIPA access control of the UE served by the cell without the CSG ID is successful.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an access control method and a mobility management entity. Background technique [0002] Femtocells are small, low-power base stations that are mainly used in small-scale indoor places such as homes and offices. The femtocell is connected to the core network of the communication operator through indoor cable, digital subscriber line (DSL, Digital Subscriber Line), optical fiber and other wired access equipment to provide specific users with access services based on wireless mobile communication networks. The femtocell is an effective supplement to the existing network deployment. It can effectively improve the coverage of indoor voice and high-speed data services. It has many advantages, such as low cost, low power, simple access, plug and play, saving backhaul, and existing Terminal compatibility, improve network coverage, etc. A home base station in a Long Term...
