Problems solved by technology

However, for the separation scenario, the existing method does not mention how the LGW knows that one end of the direct path has been deleted, that is, there is currently no way to notify the LGW that one end of the direct path has been deleted and trigger the LGW to delete the other end of the direct path
However, in the existing specification, there is no signaling process to notify the LGW that the direct path has been deleted. Although the LGW can be notified by signaling, the signaling overhead is high, and a new definition of signaling messages is required. This requires the core network nodes, For example, the SGW performs an upgrade, and the SGW forwards the relevant signaling to the LGW. This method increases the processing complexity of tunnel removal.

Embodiment 2

[0143] The S1 release process in the HeNB scenario in Embodiment 2 corresponds to the Iu release process in the HNB scenario. Among them, the UE context release request UE context release command / UE context release complete message between the home base station and the network in the HeNB scenario corresponds to the Iu release request / Iu release command / Iu between the home base station and the network in the HNB scenario Release complete message.

Embodiment 3

[0144] The S1 handover procedure in the HeNB scenario in Embodiment 3 corresponds to the SRNS Relocation Procedure (SRNS Relocation Procedure) in the HNB scenario.

[0145] Wherein, the handover between the home base station and the network in the HeNB scenario requires a message / first handover command, corresponding to the relocation between the home base station and the network in the HNB scenario requires a message / relocation command;

[0146] The second handover command sent by the home base station in the HeNB scenario to the user terminals corresponds to the downlink RRC message sent by the home base station in the HNB scenario to the UE;

[0147] The handover confirmation message sent by the user terminal in the HeNB scenario to the target macro base station corresponds to the uplink RRC message sent by the UE in the HNB scenario to the target macro base station;

[0148] The MME in the HeNB scenario and the UE context release command / UE context release complete message...

Abstract

The invention provides a removing method for a direct path, a system, a home base station and a local gateway thereof, wherein the method comprises the steps: the home base station judges whether the local area has the direct path established to the local gateway; if not, the removing process is ended; if so, the home base station sends preset data packets to the local gateway by the direct path, wherein the preset data packets are used for informing the local gateway of removing the direct path; the home base station deletes the context of a local user terminal; and the local gateway receives the preset data packets by the direct path, and then user surface parameters of the direct path are deleted. The removing method provided by the invention can be applied in separated scenes of the home base station and the local gateway, and is simple to implement.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for removing a direct path and its system, a home base station and a local gateway. Background technique [0002] In the LIPA (Local IP Access, local IP access) research project of 3GPP (The 3rd Generation Partnership Project, the third generation partnership project), only the home base station H(e)NB (referred to as HNB or HeNB) is studied in Release 10 One of them, that is, the Home NodeB or Homee Node B, that is, the home base station or the evolved home base station) and the local gateway (LGW, Local Gateway) are co-located in one physical entity, which is called Co-located GW (Co-located GW) gateway scenario); wherein, LGW (Local gateway, local gateway) has the function of PDN GW (PacketDataNetwork Gateway, packet data gateway), the function of GGSN (GatewayGPRSSupportingNode, gateway GPRS support node) and establishes a direct user plane with the hom...
