Embodiment 1

[0043] This embodiment describes that the MME sends handover instruction information to the base station, the base station switches the user to the local base station, and executes the local IP connection to the PDN (Packet Data Network, packet data network). The embodiment of the present invention provides a transfer core network IP The business method front part process, such as figure 1 shown, including:

[0044] Step 101, UE (User Equipment, user equipment) initiates an attach request message to the base station;

[0045] Step 102, base station according to S-TMSI (S-Temporary Mobile Subscriber Identity

[0046] , Temporary Mobile Subscriber Identity) and the selected network instruction to obtain the MME, if the MME cannot be obtained, select the MME through the MME selection function; then the base station forwards the attach request message to the MME in the S1-MME control signaling, and in the message at the same time Carry the indication information of the base stat...

Embodiment 2

[0072] This embodiment describes that the network side sends bearer resource modification instruction information to the UE, and the UE establishes a local IP connection of the base station to the PDN through the bearer resource modification process. The embodiment of the present invention provides a first part of the method for transferring core network IP services. Such as image 3 shown, including:

[0073] Step 301, the UE sends an attach request message to the base station;

[0074] Step 302, the base station obtains the MME according to the S-TMSI and the selection network instruction; if the MME cannot be obtained, the MME is selected through the MME selection function. Then the base station forwards the attach request message to the MME in the S1-MME control signaling, and the S1-MME control message simultaneously carries the indication information of the base station supporting the local IP egress capability and the eNB ID, and the indication information can be repre...

Embodiment 3

[0096] This embodiment describes that the network side issues LIPA attach indication information to the UE, and the UE initiates the LIPA attach process to establish a local IP connection of the home base station to the PDN. The embodiment of the present invention provides a method for transferring core network IP services. The first part of the process is as follows: Figure 5 shown, including:

[0097] Step 501, the UE sends an attach request message to the base station;

[0098] Step 502, the base station obtains the MME according to the S-TMSI and the selection network instruction; if the MME cannot be obtained, select the MME through the MME selection function, and then the base station forwards the attach request message to the MME in the S1-MME control signaling, and in the S1-MME The control message also carries the indication information of the base station's ability to support local IP egress, and the indication information can be represented by LBO Indication, etc.;...

Abstract

The embodiment of the invention provides a method, equipment and a system for transferring an Internet protocol (IP) service of a core network. The method comprises the following steps of: receiving an attach request message which is initiated by user equipment and forwarded by a base station or an access gateway, and local IP export capability indication information of the base station or the access gateway; judging the user equipment allows executing local IP access (LIPA) or not according to LIPA subscription information of the user equipment and the local IP export capability indication information; if so, sending the attach request message which carries the LIPA indication information to the base station or the access gateway; receiving a handover request message which carries LIPA bearer request information and is sent by the base station or the access gateway; and establishing a local IP bearer between a packet data network gateway and a service gateway of the base station or the access gateway according to the address of the base station or the access gateway, the LIPA bearer request information and an access point name so as to transfer the IP service of the core network locally. The invention also provides the corresponding equipment and the corresponding system.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method, equipment and system for transferring core network IP services. Background technique [0002] 3GPP proposes an access service based on H(e)NB (Home (Evolved) Base Station), which can provide higher data transmission rate by deploying H(e)NB in ​​places such as homes, shopping malls or enterprises , Smaller delay, while reducing operator operating costs. According to the agreement between the network operator and the owner of the H(e)NB, the H(e)NB can be configured in three access modes: Close, Hybrid and Open. [0003] For the hybrid H(e)NB access mode, in order to ensure the communication of CSG members, the network can reduce the established communication rate of non-CSG members; the network can also adopt different access control policies for CSG members and non-CSG members. [0004] In the process of realizing the present invention, the inventor foun...
