Embodiment Construction

[0028] In the embodiment of the present invention, the RN actively sends positioning information to the base station. The base station can directly report to the E-SMLC based on the local positioning information and the recently received RN positioning information, and does not need to interact with the RN during the reporting process, reducing the reporting delay and network resources.

[0029] see figure 2 , the flow of the method for reporting location information by the base station in this embodiment is as follows:

[0030] Step 201: Receive the location information actively reported by the relay node RN and perform save and update operations.

[0031] Step 202: Send the local positioning information and the positioning information actively reported by the RN to the enhanced serving mobile location center E-SMLC.

[0032] see image 3 , the flow of the method for the RN to report location information in this embodiment is as follows:

[0033] Step 301: Obtain local l...

Abstract

The invention discloses a method for reporting locating information. The method is used for realizing the reporting for the locating information in a relay system and reducing transmission delay and network resources. While being applied to a base station side, the method comprises the following steps of: receiving the locating information initiatively reported by an RN (Relay Node); performing storing and updating operations; and sending local locating information and the locating information initiatively reported by the RN to an enhanced service mobile location center (E-SMLC). While being applied to an RN side, the method comprises the following steps of: obtaining the local locating information and initiatively sending the locating information to the base station. The invention also discloses a device used for realizing the method.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for reporting positioning information. Background technique [0002] In the LTE-A (Long Term Evolution-Advanced, upgraded long-term evolution) system, in order to increase network coverage, the system introduces a relay node (Relay Node, RN). The RN is connected to a base station (Donor Evolved Node B, DeNB, also known as a donor base station) in a wireless manner. [0003] Before the RN is introduced, the base station and E-SMLC (Enhanced Serving Mobile Location Center, Enhanced Serving Mobile Location Center) need to exchange positioning messages. The E-SMLC sends an OTDOA (Observed Time Difference of Arrival) information request (OTDOA INFORMATION REQUEST) to the base station, and the base station feeds back an OTDOA information response (OTDOA INFORMATION RESPONSE), and carries OTDOA positioning information in the response message. The process can be found in ...
