Embodiment approach 1

[0072] A specific example of Embodiment 1 is Figure 5 As shown, it specifically includes the following steps:

[0073] Step 1: The UE context in the source eNodeB contains roaming restriction information, and the source eNodeB entity configures the measurement control process of the UE according to the roaming restriction information;

[0074] The roaming restriction information is provided when the connection is established or when the last TA (Tracking Area) is updated, and the source eNodeB provides measurement information to the UE, which helps to control the UE's connection movement process.

[0075] Step 2: The UE triggers reporting of the measurement report according to specified rules;

[0076] The UE may report a measurement report to the source eNodeB according to a specified rule such as system information.

[0077] Step 3: According to the measurement report reported by the UE and the RRM (Radio Resource Management) information of the source eNodeB, when the UE ...

Abstract

A method, a device and a system are used to establish an S1 signaling connection in an evolution network in the mobile communication field, wherein a source evolution base station eNodeB sends a switching request message carrying the S1 signaling connection parameter information of an original eNodeB to an object eNodeB, thereby initiating the switching process from a use equipment (UE) to the object eNodeB; when the UE enters an object cell, the object eNodeB allocates the S1 signaling connection parameter of a new eNodeB, and sends a switching finishing message which carries the S1 signaling connection parameters of both the original eNodeB and the new eNodeB to an evolutional grouping core EPC; the EPC which stores the S1 signaling connection parameters of the new eNodeB realizes the establishment of S1 signaling connection between the EPC and the object eNodeB. The embodiment of the method, the device and the system effectively solves the problem of the prior art that S1 signaling connection can not be established between an object eNodeB and an EPC after the switching of a UE.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method, device and system for establishing an S1 signaling connection in an evolution network. Background technique [0002] In the SAE (System Architecture Evolution) / LTE (Long Term Evolution) network, the S1 interface is the interface between eUTRAN (evolved radio access network) and CN Node (core network node, including MME / UPE). These are the control plane interface S1-CP and the user plane interface S1-UP. Wherein S1-CP is an interface between eUTRAN and MME (control plane entity), and S1-UP is an interface between eUTRAN and UPE (user plane entity). [0003] In SAE / LTE network, between eNodeB (evolved base station included in eUTRAN) and MME, the logical connection between two S1-CP application part entities is called S1 signaling connection, and the S1-CP application part is S1 control plane interface Applied section agreement. In the current SAE / LTE ...
