Problems solved by technology

Specifically, if the range of the MDT area is set as a list of cell IDs or as the entire area, the SRNC has already obtained the cell IDs of the serving cells under the DRNC and the PLMN IDs served, and can determine whether the cells under the DRNC are within the range. However, if The range of the MDT area is set as the LAI list or RAI list. Currently, the SRNC does not know the LAI and RAI of the cells under the DRNC, and the SRNC has no way to judge

Embodiment 1

[0063] Embodiment 1 describes that the SRNC sends the MDT configuration information to the DRNC, and the DRNC judges whether the UE's serving cell under the DRNC is within the MDT area. If not, the DRNC sends a message to instruct the SRNC to release the MDT configuration configured on the UE. , image 3 The illustrated method may include the steps of:

[0064] Step 301: SGSN sends CN initiated tracking message to SRNC. The message includes MDT configuration information, where the MDT type is set to immediate, and the message also includes the measurement object, reporting mechanism, and MDT area range. The area scope may be a set of cell identity lists, or LAI identity lists, or RAI identity lists, or the entire network. If the message contains an MDT PLMN list, set the area scope to the entire network to indicate that MDT needs to be performed within the range indicated by the MDT PLMN list, and if the message does not contain an MDTPLMN list, set the area scope to the ent...

Embodiment 3

[0086] Embodiment three has described the process that SRNC obtains the area range identification of the sub-district under DRNC, and then judges whether the sub-district under DRNC is within the MDT area range, Figure 5 The illustrated method may include the steps of:

[0087] Step 501: SGSN sends CN initiated tracking message to SRNC. The message includes MDT configuration information, where the MDT type is set to immediate, and the message also includes the measurement object, reporting mechanism, and MDT area range. The area scope may be a set of cell identity lists, or LAI identity lists, or RAI identity lists, or the entire network. If the message contains an MDT PLMN list, set the area scope to the entire network to indicate that MDT needs to be performed within the range indicated by the MDT PLMN list, and if the message does not contain an MDTPLMN list, set the area scope to the entire network to indicate that MDT must be performed within the scope of the current se...

Embodiment 4

[0094] Embodiment 4 describes the process that the SRNC obtains the area range identification of the cell under the DRNC, and then judges whether the cell under the DRNC is within the MDT area range, Image 6 The illustrated method may include the steps of:

[0095] Step 601: SGSN sends CN initiated tracking message to SRNC. The message includes MDT configuration information, where the MDT type is set to immediate, and the message also includes the measurement object, reporting mechanism, and MDT area range. The area scope may be a set of cell identity lists, or LAI identity lists, or RAI identity lists, or the entire network. If the message contains an MDT PLMN list, set the area scope to the entire network to indicate that MDT needs to be performed within the range indicated by the MDT PLMN list, and if the message does not contain an MDTPLMN list, set the area scope to the entire network to indicate that MDT must be performed within the scope of the current serving PLMN M...

Abstract

The invention relates to a method for supporting MDT measurement movement and releasing MDT configuration which is configured at UE. Whether a present service district is in an MDT area scope is determined through DRNC, SRNC is instructed to release the MDT configuration configured at the UE, or the SRNC acquires sufficient information through a DRNC or ANR process, whether a district below the DRNC is in the MDT area scope is determined, if not, the SRNC releases the MDT configuration configured at the UE, so the MDT measurement configuration configured at the UE is deleted, and thereby the MDT measurement scope is controlled to be in a configuration scope, and modification on the protocol is reduced to a maximum degree.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method for supporting MDT to move under one or more public land mobile networks, and deleting the MDT measurement configured in UE in time when continuous measurement is not needed. Background technique [0002] The system structure of the Universal Mobile Telecommunication System (UMTS for short) is as follows: figure 1 shown. The following is a description of the UMTS system structure. [0003] figure 1 101E-PDN (Extern Packet Data Network) is an external public data network that provides various types of packet data. The packet data is transmitted from the external network to 103 through the predetermined interface 102 to the gateway general packet radio service (hereinafter referred to as GPRS) support node (hereinafter referred to as the gateway GPRS support node to GGSN). After receiving the data, the GGSN sends the data to 105 serving GPRS support node (he...
