Problems solved by technology

For example, when a UE accesses a hybrid HeNB / HNB, if the UE does not belong to the CSG, then the UE accesses the HeNB / HNB as a non-CSG member, and LIPA cannot be activated for the UE at this time

Embodiment 1

[0039] Figure 4 The flow chart of the method provided by Embodiment 1 of the present invention, such as Figure 4 As shown, this embodiment may include the following steps:

[0040] Step 401: UE sends a request for accessing Packet Data Network (PDN) to MME / SGSN, and the PDN is identified by APN.

[0041] Step 402: The MME / SGSN judges whether the UE is a CSG member according to the information about access to LIPA services; if the UE is a CSG member, execute step 403; otherwise, execute step 404.

[0042] Step 403: On the premise that the base station currently accessed by the UE has equipment capabilities that support LIPA: if the CSG list accessible to the UE includes the APN in step 401, and the LIPA access parameter corresponding to the APN is LIPA-Only, Then the MME / GSGN activates the LIPA service for the UE; if the CSG list accessible to the UE includes the APN in step 401, and the LIPA parameter corresponding to the APN is LIPA-Prohibit, then the MME / GSGN refuses to ...

Embodiment 2

[0057] Embodiment 2 is an alternative to Embodiment 1. The difference is that in Embodiment 2, when the network allows other types of base stations to access, the network needs to further determine whether the APN is included in the relevant information that can access LIPA services. Determine whether the APN currently requesting access is an APN that supports LIPA services. Only when the APN is included in the relevant information that can access the LIPA service, and the APN supports the LIPA service, then the type of the APN is judged to decide whether to provide the LIPA service for the UE. Specifically, replace the Figure 4 406 steps in the other steps with Figure 4 The steps in are all the same:

[0058] If the network node MME / SGSN determines that the UE is allowed to access the non-closed base station, then the relevant information that the base station currently accessed by the UE has the equipment capability to support LIPA and can access the LIPA service include...

Embodiment 3

[0060] Figure 5 The method flowchart provided for the third embodiment of the present invention, such as Figure 5 As shown, this embodiment may include the following steps:

[0061] Step 501: UE sends a request to access PDN to MME / SGSN, and the PDN is identified by APN.

[0062] Step 502: The MME / SGSN judges whether the UE is a CSG member according to the information about access to LIPA services; if the UE is a CSG member, execute step 503; otherwise, execute step 504.

[0063] Step 503: On the premise that the base station currently accessed by the UE has the device capability to support LIPA: if the CSG list accessible to the UE includes the APN in step 501, and the LIPA access parameter corresponding to the APN is LIPA-Only, Then the MME / SGGN activates the LIPA service for the UE; if the CSG list accessible to the UE includes the APN in step 501, and the LIPA parameter corresponding to the APN is LIPA-Prohibit, then the MME / GSGN refuses to activate the LIPA service fo...

Abstract

The invention provides a method for supporting user equipment (UE) to access local IP access (LIPA) service. The method comprises the following steps: a network node receives a request for accessing a packet data network (PDN) sent by the UE, and the PDN is identified by an APN of a service access point; the network node determines whether the UE is permitted to access the LIPA service via an unclosed base station based on LIPA accessibility information; if the UE is permitted to access the LIPA service, the network node determines whether a requirement for connecting the UE to the LIPA service is satisfied based on the LIPA accessibility information and device capability determination of a present access base station of the UE; if the requirement is satisfied, the LIPA service is activated for the UE. By using the method, an application range of the LIPA service can be expanded.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a method for supporting user equipment (UE) to access local IP access (LIPA) services. Background technique [0002] figure 1 It is a system architecture diagram of an existing system architecture evolution (SAE), wherein a user equipment (UE) 101 is a terminal equipment for receiving data. Evolved Universal Terrestrial Radio Access Network (E-UTRAN) 102 is a radio access network including macro base stations (eNBs) that provide UEs with an interface to access the radio network. Mobility Management Entity (MME) 103 is responsible for managing UE's mobility context, session context and security information. Serving Gateway (SGW) 104 mainly provides user plane functions, and MME 103 and SGW 104 may be in the same physical entity. The packet data network gateway (PGW) 105 is responsible for functions such as charging and lawful interception, and may also be in the same physica...
