Embodiment Construction

[0048] For ease of explanation and understanding, figure 1 Shows a schematic diagram of signaling interaction in a connection establishment method in the prior art, such as figure 1 As shown, the procedure for establishing a connection between User Equipment (UE) and Network Device (NW) each time is as follows:

[0049] The user equipment executes step S11: sends an attachment request including a public data network (Public Data Network, PDN) connection request to the network side device, and the network side device executes step S12: responds to attachment request response information, and enters the bearer context activation preparation state, where: The attach request response information includes a request to activate the default bearer context. Furthermore, the user equipment performs step S13: replying to the attachment completion information, including the activation of the default bearer context acceptance information. For the network-side device, step S14 can be performe...

Abstract

The invention discloses a method for establishing a connection, network side equipment and user equipment. The method includes the following steps: when an attachment request from the user equipment is received, and the attachment request includes a message indicative of a request for that the network side equipment uses connection parameters saved when a connection between the network side equipment and the user equipment is established previously, an attachment request response message is sent to the user equipment, wherein the attachment request response message involves the steps of activating a default bearing context request, obtaining an additional parameter required to activate the default bearing context, and entering a bearing context activation state by utilizing the additionalparameter required to activate the default bearing context; and a connection is re-established with the user equipment. Through adoption of the scheme, a process of establishing the connection can besimplified, the efficiency of establishing the connection is improved, and the duration of connection establishing is reduced.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a method for establishing a connection, network side equipment and user equipment. Background technique [0002] After the user equipment (User Equipment, UE) loses connection with the network side device, is disconnected for a short time, or is disconnected for a long time, or after the power-on / off cycle of the UE, the UE and the network side device will re-establish a connection. [0003] At present, the process of establishing a connection between the UE and the network side device is as follows: the UE sends an attachment request including a public data network (Public Data Network, PDN) connection request to the network side device, the network side device replies with the attachment request response message, and enters Bearer context activation preparation state, wherein: the attach request response information includes a request to activate the default bearer context. Furt...
