Embodiment Construction

[0045] In order to reduce the processing load on the network side when a terminal performs network attachment, an embodiment of the present invention provides a terminal attachment method in the Evolved Universal Mobile Communications System Terrestrial Radio Access Network (E-UTRAN). In this method, the MME receives the attachment After the request message, if it is determined that the original tunnels on the S11 interface and S5 / 8 interface can be used for attachment, the operation of deleting the original tunnel and establishing a new tunnel will no longer be performed, but an attach acceptance message will be sent directly to the base station, and the base station will then send the attach acceptance message to the base station. An Attach Accept message is sent to the terminal.

[0046] see figure 2 , the terminal attachment method in the E-UTRAN provided by the embodiment of the present invention includes the following steps:

[0047] Step 20: The MME receives the attac...

Abstract

The embodiment of the invention discloses a terminal attachment method and terminal attachment equipment, which relate to the technical field of wireless communication and are used for reducing the processing load of a network side in the network attachment of a terminal. The method comprises that: after receiving an attach request message, from the terminal, forwarded by an evolved Node B (eNB), a mobility management entity (MME) determines whether tunnels on an S11 interface and an S5 / 8 interface can be used for the attachment or not; and after determining that the tunnels on the S11 interface and the S5 / 8 interface can be used for the attachment, the MME gives the operations of deleting an original tunnel and establishing a new tunnel up, and transmits an attachment acceptance message to the terminal by the eNB. By the method and the equipment, the processing load of the network side in the network attachment of the terminal can be reduced.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a terminal attachment method and equipment. Background technique [0002] Due to the instability and complexity of the air interface, calls may be dropped when the terminal has successfully attached to the network side. At this time, the terminal (UE) registers with the network by sending an attach request (attach request) message to the base station (eNB) and the mobility management entity (MME) again. According to the description of the 23401 protocol, if the UE reattaches to the same MME without deattaching in advance, it is necessary to delete the tunnel of the original MME in the relevant Serving Gateway (SGW) and Packet Data Gateway (PGW), and the MME selects a SGW, Create a new tunnel and default bearer. [0003] According to the 23401-940 protocol, when the UE reattaches to the same MME without deattaching in advance, the process is as follows: [0004] St...
