Embodiment 1

[0022] Such as figure 2 As shown, it is a flow chart of the method for establishing a local network bearer in Embodiment 1 of the present invention. The UE instructs the MME in the core network that the PDN connection to be established is connected to the local network, and then the MME instructs the HeNB to establish a bearer to the local network, so that the UE can access the local network through the HeNB. This embodiment comprises the following steps:

[0023] In step S201, the UE sends an Attach Request (attach request) message to the HeNB. The attach request message includes Attach Type (attach type), Ciphered Options Transfer Flag (encrypted transfer option identifier) ​​and other information. Among them, in one embodiment of the present invention, if the UE initially accesses and accesses the local network, the UE needs to notify the MME in the core network that the PDN connection to be established is connected to the local network instead of the traditional SGi Th...

Embodiment 2

[0065] Such as image 3 As shown, it is a flowchart of a method for establishing a local network bearer in Embodiment 2 of the present invention. This embodiment is similar to Embodiment 1. In this embodiment, the UE indicates to the MME in the core network that the PDN connection to be established is connected to the local network; then the MME instructs the HeNB to establish a bearer to the local network; the uplink data of the UE received by the HeNB from these radio bearers is directly transmitted to the corresponding local network, and the downlink data received by the HeNB from the local network is transmitted through the corresponding radio bearer For UE, this embodiment includes the following steps:

[0066] In step S301, the UE initiates a PDN Connectivity Request (PDN connection request) message through the HeNB, and the PDN Connectivity Request message includes information such as the request type, the APN requested by the UE, and the PDN type. Among them, in one e...

Abstract

The invention provides a bearer establishing method of a local network. User equipment (UE) sends a packet data network (PDN) connection request through a home enhanced node B (HeNB) and indicates that PDN connection requested to be established by a mobility management entity (MME) is to connect the local network; the MME sends the bearer for establishing the local network to the UE according to the indication and inhibits information borne by the bearer for the local network to the HeNB; and the HeNB establishes the radio bearer of the local network for the UE according to the indication andthe data transmission between the UE and the local network according to the radio bearer. The invention solves the problem that the UE establishes the radio bearer of the local network through the HeNB, thereby enabling the UE to be smoothly accessed to the local network through the HeNB.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and device for establishing a bearer of a local network. Background technique [0002] In 3GPP's LTE (Long Term Evolution, long-term evolution), HeNB (Home Evolved NodeB, home evolution base station) will be deployed in homes, offices, campuses and other places, which are used to serve those who often live, work and study in the above places User. The cell covered by the HeNB adopts a special name, that is, a CSG cell (Closed Subscriber Group, closed subscriber group cell), which is distinguished from a conventional macro cell. [0003] In order to allow the IP-capable UE (User Equipment) wirelessly connected to the HeNB to connect with other IP-capable devices in the home, the HeNB needs to support the feature of local IP access to the local network. Wherein, the aforementioned local network may include a home network or a local Internet network...
