Embodiment 1

[0041] Embodiment 1 of the present invention proposes an access control method, such as figure 1 As shown, the specific processing flow is as follows:

[0042] 101. The base station obtains the network access capability supported by the UE.

[0043] The base station obtains the network access capability supported by the UE from the received UE context establishment message sent by the network device, or the base station obtains the network access capability supported by the UE from the received wireless capability message reported by the UE. access capability.

[0044] 102. The base station checks whether the access capability of the UE matches the currently accessed network.

[0045] Among them, the base station checks whether the UE's access capability matches the currently accessed network, or the base station checks whether the UE's capability matches the capability specified in the protocol version, that is, checks whether the access capability supported by the UE is st...

Embodiment 2

[0085] In the technical solution proposed by Embodiment 2 of the present invention, the network device is an MME as an example to elaborate. The base station returns initial context setup failure to the MME, and carries a clear S1 AP cause value. Such as figure 2 As shown, the specific processing flow is as follows:

[0086] 201. The eNB obtains the network access capability supported by the UE.

[0087] 202. The eNB checks whether the access capability of the UE matches the currently accessed network.

[0088]Among them, whether the UE's access capability is the same as the currently accessed network includes the following three situations:

[0089] The first case: the base station determines that the access capability of the UE does not match the currently accessed network.

[0090] The second case: the base station determines that the capability of the terminal does not match the capability corresponding to the version specified in the protocol.

[0091] The third case...

Embodiment 3

[0097] In the technical solution proposed in Embodiment 3 of the present invention, the network device is an MME as an example to describe in detail. In the technical solution proposed in Embodiment 3 of the present invention, the base station processes the UE's access capability mismatch, sends an InitialContext Setup Response to the MME, and carries the minimum value of the terminal capability as an example to describe in detail.

[0098] Such as image 3 As shown, the specific processing flow is as follows:

[0099] 301. The eNB obtains the network access capability supported by the UE.

[0100] 302. The eNB checks whether the access capability of the UE matches the currently accessed network.

[0101] Whether the UE's access capability matches the currently accessed network, specifically includes the following three situations:

[0102] The first case: the base station determines that the access capability of the UE does not match the currently accessed network.

[010...

Abstract

The invention discloses an access control method and device. The method comprises the steps that a base station acquires an access capability supported by UE and accessing a network; the base station verifies whether the access capability of the UE is matched with a currently accessed network; and if the base station determines that the access capability is not matched with the currently accessed network, the base station sends a first message of informing failure of creation of a UE initial context to the network device, so as to solve a problem that UE constantly tries to access specific eNB and MME networks but always fails to provide normal service.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to an access control method and device. Background technique [0002] With the development of wireless communication technology, in the long-term evolution communication system, the evolved base station (evolved Node B, eNB) will check some terminal information from the perspective of security and self-protection, or from the perspective of improving user experience. For these capabilities, if the verification fails, the initial context setup failure (Initial Context SetupFailure) is returned to the core network, carrying an unspecified (Unspecified) cause value. The core network receives the Unspecified cause value. However, in the current situation, not all eNBs of manufacturers will verify the terminal capabilities. Correspondingly, the core network equipment sometimes receives the initial context establishment failure message and the Unspecified cause value, an...
