Problems solved by technology

Because it is necessary to use an independent message to reply to the previous control message and NAS message, this not only increases the complexity of the processing process of UE and eNB, but more importantly, it also wastes precious air interface resources and S1 interface resources, reducing the resource utilization efficiency of the communication system

Embodiment Construction

[0047] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] The basic idea of ​​the present invention is that in the application scenario where NAS messages need to be transmitted, during the RRC connection reconfiguration process, the eNB carries the downlink NAS message in the RRC connection reconfiguration message sent to the UE, and the UE completes the RRC connection reconfiguration process Afterwards, the uplink NAS message is carried in the RRC connection reconfiguration complete message replied to the eNB, and the eNB carries the uplink NAS message in the S1 interface message and sends it to the MME.

[0049] A preferred embodiment is given below to briefly describe the RRC connection reconfiguration method of the present invention. figure 2 It is a signaling flowchart of the RRC connection...

Abstract

The invention discloses a radio resource control (RRC) connection reestablishment method. The method comprises the following steps that: in the application scenarios needing the transmission of a network attached storage (NAS) message, evolution node B (eNB) sends an RRC connection reestablishment message comprising a downlink NAS message to user equipment (UE); the UE carries an uplink NAS message in an RRC connection reestablishment completion message returned by the eNB after completing processing the RRC connection reestablishment; and eNB fills the uplink NAS message returned by the UE to an S1 interface message to send the message to a mobile management entity (MME). By the RRC connection reestablishment method of the invention, the transmission of the NAS message is completed through the RRC connection reestablishment completion message and the S1 interface message so as to avoid singly transmitting other messages used for the transmission of the NAS message, save null interface resources and the S1 interface resource and improve the resource utilization efficiency of a communication system.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a radio resource control (RRC) connection reconfiguration method. Background technique [0002] The Long Term Evolution (LTE) wireless network is a flat network, in which the Evolved Universal Mobile Communications System Radio Access Network (EvolvedUTRAN, E-UTRAN) consists of a Base Station (Evolved Node Base, eNB) and an Evolved Packet Switching Center (Evolved Packet Core, EPC) composition. Compared with the 3G technology, the biggest change of the LTE network is that the radio access network (Radio Access Network, RAN) part removes the radio network controller (Radio NetWork controller, RNC), which reduces the network delay. In E-UTRAN, multiple eNBs form a set, and are connected to the EPC through an S1 interface, and each eNB is connected through an X2 interface. [0003] The 3rd Generation Partnership Project (3GPP) RRC protocol describes the RRC connection reconfigura...
