Embodiment Construction

[0027] In order to make the purpose, technical solutions and beneficial effects of the embodiments of the invention more clear, the specific implementation manners of the embodiments of the invention will be described in detail below in conjunction with the accompanying drawings.

[0028] In the embodiment of the present invention, the access network node and the core network node may be eNB and MME in the SAE / LTE system respectively, and at this time, the interface between the eNB and MME is the S1 interface, or the RNC and SGSN in the UMTS system, At this time, the interface between the RNC and the SGSN is the Iu interface. In the embodiment of the present invention, the SAE / LTE system is taken as an example for description. The interface configuration relationship referred to below refers to the interface configuration between the UE and the HNB and / or between the HNB and the core network node.

[0029] The embodiment of the present invention first proposes a method suitab...

Abstract

The invention discloses a method for routing a non access stratum (NAS) message, comprising the following steps: user equipment (UE) sends a first NAS message to an access network node; a core network node is selected according to incidence relation information, and the selected core network node is taken as a second core network node which is provided with interface configuration with a home base station (HNB) associated with the UE; and the first NAS message is sent to the second core network node. The invention provides the UE, the access network node and the core network node. The use of the method can reduce the interface connection between the access network node and the core network node, and reduce the influence on network functions such as user mobility and the like.

Description

technical field [0001] The embodiment of the present invention relates to the field of mobile communication, in particular to a method for routing non-access stratum messages. Background technique [0002] E-UTRAN (Evolved UMTS Radio Access Network, E-UTRAN) is also called Long Term Evolution (LTE), and the corresponding core network is System Architecture Evolution (SAE). For details, please refer to the protocol 3GPPTS36 .300. The evolved base stations (Evolved NodeB, eNB) in E-UTRAN are connected through the X2 interface, and the eNB is connected with the core network equipment mobility management entity / serving gateway MME / S-GW (Mobility Management Equipment / Serving Gateway) through the S1 interface . The S1 interface of E-UTRAN is divided into control plane and user plane. The control plane interface is connected to the MME, called S1-MME; the user plane interface is connected to the S-GW. [0003] In the E-UTRAN network, an S1-MME interface is an SCTP coupling, whi...
