Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042]The embodiment of the present invention discloses a method and system for realizing the initial access of the user equipment. When the user equipment sends a connection establishment request message, the system will save the identification information of the cell where the user equipment is located. When the connection establishment request of the user equipment is received again message, determine whether the two cell identification information are consi...

Abstract

The invention provides a method and a system for realizing initial access of user equipment. The method comprises the following steps: storing a first connection establishment request message and first cell identifier information transmitted by the user equipment and transmitting the first connection establishment request message to the user equipment after distributing system resources for the user equipment; judging whether the user equipment is positioned at the same cell when receiving a second connection establishment request message and second cell identifier information transmitted by the user equipment, if so, retransmitting the first connection establishment request message, and if not, redistributing the system resources for the user equipment and transmitting the second connection establishment request message; and receiving a connection establishment finished message returned by the user equipment according to the connection establishment of the first connection establishment request message or the second connection establishment request message. By adopting the embodiment of the invention, when the user equipment is not positioned in the same cell, a connection establishment message transmitted by the system can be still received, so as to carry out the initial access process and improve the success rate of the initial access.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically relates to a method and system for realizing initial access of user equipment. Background technique [0002] In the mobile communication system, the initial access process of UE (User Equipment, user equipment) has corresponding technical regulations. With the continuous development of the third generation mobile communication technology, the initial access method of UE is also constantly developing. [0003] In the UMT S (Universal Mobile Telecommunications System, universal mobile communication system) system, in the existing UE initial access method, usually the UE uses PRACH (Physical Random Access Channel, physical random access channel) on the main carrier of the cell Send an RRC (Radio Resource Control, radio resource control) connection request message, after the network side receives the RRC connection request message, send an RRC connection est...
