Problems solved by technology

However, since the signal attenuation at high frequency points is relatively severe, and the coverage of new low-power cells is relatively small, and they are not in the same site as existing cells, therefore, if the user moves between these new cells, or in the The movement between the new cell and the existing cell will inevitably lead to frequent handover process, which makes the frequent transmission of user information between the base stations, thus causing a great signaling impact on the core network, and thus curbing the introduction of a large number of small cell base stations on the wireless side

Embodiment 1

[0074] This embodiment provides a paging method applied to the core network side, including:

[0075] Obtain relevant information of DCGW;

[0076] According to the related information of the DCGW, the paging message is delivered.

[0077] Wherein, the acquisition of relevant information of the DCGW is:

[0078] Obtain the relevant information of the DCGW through the S1 interface.

[0079] Here, the core network refers to core network equipment, such as MME.

[0080] The message carrying the DCGW-related information may be a public S1 interface message, or a UE-specific S1 interface message; wherein, the public S1 interface message may use one or more of the following: S1 establishment request message, base station configuration update message; UE The dedicated S1 interface message may use one or more of the following: INITIALUEMESSAGE message, UPLINKNASTRANSPORT message. In practical applications, the messages transmitted by the S1 interface are not limited to the S1 inte...

Embodiment 2

[0114] The application scenario of this embodiment is: a DCGW is deployed in a small base station environment; and the DCGW is an independent network element, and an S1 interface exists between the DCGW and the MME.

[0115] The paging method of this embodiment, such as Figure 4 shown, including the following steps:

[0116] Step 401: SeNB initiates an S1 interface establishment request to DCGW;

[0117] Here, the S1 interface establishment request carries SeNB information; the SeNB information may include SeNB-related configuration information such as SeNBID.

[0118] Step 402: DCGW sends an S1 interface establishment response to SeNB, and then executes step 403;

[0119] Here, steps 401-402 are the process of establishing an interface between the SeNB and the DCGW, which can be implemented by reusing the existing S1 interface establishment process.

[0120] The S1 interface setup response includes DCGW-related information; wherein, the DCGW-related information may includ...

Embodiment 3

[0134] The application scenario of this embodiment is: the application scenario of this embodiment is: a DCGW is deployed in a small base station environment; and UE-related S1 interface control plane signaling can only exist between the MeNB and the MME.

[0135] The paging method of this embodiment, such as Figure 5 shown, including the following steps:

[0136] Step 501: SeNB initiates an S1 interface establishment request to DCGW;

[0137] Here, the S1 interface establishment request carries SeNB information; the SeNB information may include SeNB-related configuration information such as SeNBID.

[0138] Step 502: DCGW sends an S1 interface establishment response to SeNB, and then executes step 503;

[0139] Here, steps 501-502 are the process of establishing an interface between the SeNB and the DCGW, which can be implemented by reusing the existing S1 interface establishment process.

[0140] The S1 interface setup response includes DCGW-related information; wherein,...
