Abstract

The present invention discloses a method and equipments for feeding back MDT Log. Terminal equipment rationally chooses whether to send Log available message to the network based on the fact whether present attribution zone(s) of terminal equipment is the valid attribution zone(s), or report the information of present attribution zone(s) to network side, then the network side judges whether to acquire MDT Log, so as to avoid feeding back MDT Log and further causing loss of valid MDT Log in case of no correspondence of present attribution zone(s). Moreover, terminal equipment can decide whether to report Log available message to the network side according to the condition of actual attribution zone(s), which avoids unnecessary reporting of MDT Log and validly saves radio resource of the system.

First claim

What is claimed is:

1. A method for feeding back minimization drive test (MDT) logs, the method comprising:
determining whether a terminal equipment connects to a target cell by switching from an idle state to a connection state, or reestablishes to a target cell in a connection state, or alters from a current attribution cell to a target cell during a connection state, and upon positive determination thereof, said terminal equipment verifying whether feeding back MDT logs across arbitrary attribution zones is permitted;
if said terminal equipment verifies that feeding back the MDT log across arbitrary attribution zones is not permitted, said terminal equipment judging whether an attribution zone corresponding to evolved Node B(s) (eNB(s)) of said target cell is a predefined valid attribution zone; and
if a judgment result is “Yes”, said terminal equipment sending log available message to eNB(s) of said target cell.

2. The method as claimed in claim 1 , wherein said terminal equipment verifying whether feeding back MDT logs across arbitrary attribution zones is permitted comprises:
determining whether said terminal equipment is set to permit to feed back MDT logs to eNB(s) in one or several specified attribution zones, or said terminal equipment receives a message carrying configuration information that permits said terminal equipment to feed back MDT logs eNB(s) in one or several specified attribution zones, and upon positive determination thereof, said terminal equipment verifying that feeding back MDT logs across arbitrary attribution zones is not permitted, but only feeding back MDT logs to eNB(s) in the one or several specified attribution zones is permitted; and
determining whether said terminal equipment receives a message carrying configuration information that permits said terminal equipment to feed back MDT logs to eNBs in arbitrary attribution zones, or said terminal equipment is set to permit to feed back MDT logs to eNBs in arbitrary attribution zones, and upon positive determination thereof, said terminal equipment verifying that feeding back MDT logs across arbitrary attribution zones is permitted;
wherein, said one or several specified attribution zones are predefined valid attribution zones.

3. The method as claimed in claim 2 , wherein
when said terminal equipment receives MDT configuration when it is belonging to a public land mobile-communication network (PLMN), then said PLMN is verified as a valid attribution zone, and said terminal equipment is set to permit to feed back MDT logs to eNB(s) in the PLMN;
when said terminal equipment is configured as that one or several PLMNs are valid attribution zones, said terminal equipment is set to permit to feed back MDT logs to eNBs in said one or several PLMNs, and
when said terminal equipment is configured as that the corresponding zones of one or several eNBs are valid attribution zones, said terminal equipment is set to permit to feed back MDT logs to said one or several said eNBs.

4. The method as claimed in claim 2 , wherein the predefined valid attribution zones are specifically one or several kinds of the following information:
PLMN information, cell list information, eNB list information, SA zones list information, tracking area list information, and other-information that can indicate location zones where the terminal equipment attributes.

5. The method as claimed in claim 2 , wherein when said terminal equipment verifies that feeding back MDT logs to arbitrary attribution zones is permitted, said method further comprises:
said terminal equipment judging whether the MDT logs are saved in the terminal equipment at present;
if “Yes”, said terminal equipment judging whether said MDT logs are valid; and
if all or parts of MDT logs are valid, said terminal equipment sending log available message to eNB(s) of said target cell.

6. The method as claimed in claim 2 , wherein when said terminal equipment verifies that feeding back MDT logs to eNB(s) in the one or several specified attribution zones is permitted, said method further comprises:
said terminal equipment judging whether the MDT logs are saved in the terminal equipment at present;
if “Yes”, said terminal equipment judging whether said MDT logs are valid;
if all or parts of said MDT logs are valid, said terminal equipment judging whether attribution zone(s) corresponding to said target cell belongs to said one or several specified attribution zones;
if “Yes”, said terminal equipment sending log available message to eNB(s) of said target cell; and
if “No”, said terminal equipment abandoning sending log available message to eNB(s) of said target cell and continuing keeping said MDT log.

7. The method as claimed in claim 5 , wherein after said terminal equipment sends-sending the log available message to eNB(s) of said target cell, the method further comprises:
said terminal equipment reporting all valid MDT logs saved at present to eNB(s) of said target cell after receiving a log reporting request sent by said target cell.

8. The method as claimed in claim 7 , wherein after said terminal equipment reporting MDT logs to said eNB, the method further comprises:
said terminal equipment deleting MDT Logs that have reported.

9. The method as claimed in claim 1 , wherein if a judgment result is “No”, the method further comprises:
said terminal equipment abandoning sending log available message to eNB(s) of said target cell, and continuing keeping said MDT Logs.

10. A terminal equipment comprising:
a storage module, which is used to save minimization drive test (MDT) logs;
a verification module, which is used to verify whether feeding back MDT logs across arbitrary attribution zone is permitted when said terminal equipment connects to a target cell by switching from an idle state to a connection state, or reestablishes to a target cell in a connection state, or alters from a current attribution cell to a target cell during a connection state;
a judgment module, which is used to judge whether an attribution zone corresponding to evolved Node B(s) (eNB)(s) of said target cell is a predefined valid attribution zone when said verification module verifies that feeding back MDT Logs across arbitrary attribution zone is not permitted;
a sending module, which is used to send log available message to eNB(s) of said target cell when the judgment result of said judgment module is “Yes”.

11. The terminal equipment as claimed in claim 10 , wherein through said verification module verifies whether feeding back MDT Logs L-g across arbitrary attribution zones is permitted in following manners:
determining whether said verification module verifies that said terminal equipment is set to permit to feed back MDT logs to eNB(s) in one or several specified attribution zones, or verifies that a message carrying configuration information that permits said terminal equipment to feed back MDT logs to eNB(s) in one or several specified attribution zones is received, and upon positive determination thereof, said verification module verifies that feeding back MDT logs across arbitrary attribution zones is not permitted, but only feeding back MDT logs to corresponding eNB(s) in one or several attribution zones is permitted;
determining whether said verification module verifies that a message carrying configuration information that permits said terminal equipment to feed back MDT logs to eNBs in arbitrary attribution zones is received, or verifies that said terminal equipment is set to permit to feed back MDT logs to eNBs in arbitrary attribution zones, and upon positive determination thereof, said verification module verifies that feeding back MDT logs across arbitrary attribution zones
