Problems solved by technology

[0007] In the current LTE system, there are only specific deployment methods for various core network functions (including MME, SGW, and PGW) serving UEs. For example, there is no corresponding deployment method for MME, SGW, PGW, and HSS serving RN, so there is no corresponding service implementation process

Embodiment Construction

[0056] 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.

[0057] In the prior art, entities of various core network functions (including MME, SGW, and PGW) serving UE are deployed in the core network, and there are already service implementation procedures for each core network functional entity serving UE. For the core network, the RN is equivalent to the UE, and various core network functions serving the UE are similar to those serving the RN. Therefore, if referring to the deployment method of each core network functional entity serving the UE, each core network function serving the RN is also deployed in the core network, then the MME and SGW serving the UE need to be set in the core network , PGW, and MME, SGW, and PGW serving RN, so that when the service is realized, an information transmission nee...

Abstract

The invention provides business realization method, equipment and system in a long-term evolution network. The method comprises the steps: setting a relay node (RN) between user equipment (UE) and a donor base station (DeNB); terminating an S1 interface between a core network and a wireless access network on the RN; setting the function of the core network which serves the RN in the DeNB; in uplink, transmitting the information of the S1 interface of the UE to the DeNB by the RN, processing the function of the core network of the RN by the DeNB, and then transmitting to the core network; in downlink, processing the function of the core network of the RN by the DeNB and transmitting the information of the S1 interface of the UE to the RN after the DeNB receives the information of the UE from the core network by the S1 interface. The DeNB in the wireless access network integrates the function of the core network which serves the RN, and all kinds of processing of the core network of theRN is executed in the DeNB, thereby ensuring the business realization.

Description

technical field [0001] The present invention relates to LTE (Long Term Evolution) technology, in particular to a service realization method and system in an LTE network. Background technique [0002] LTE is the next evolution target of the mobile broadband network standard defined by 3GPP (Third Generation Partnership Project), which enables efficient use of existing and future wireless frequency bands. The LTE system consists of three parts: CN (core network), eNodeB (base station) of the access network, and UE (user equipment). Among them, the eNodeB of the RAN (radio access network) is connected to the network entity in the CN through the S1 interface, and the UE Connect with eNodeB through Uu interface. [0003] In order to enhance the LTE system, a solution of adding an RN (relay node) to the architecture of the access network is currently proposed. The RN node is set between the UE and the eNodeB, which can be regarded as an extension of the eNodeB, providing more ec...
