Abstract

A method, an apparatus, and a system for detecting a radio network problem are disclosed. The method includes: when a radio network problem occurs on a user equipment (UE), a first base station controlling a cell that a radio resource control (RRC) connection established with the UE, receives problem information about the radio network problem sent by the UE, in a procedure of re-establishing the RRC connection by the UE, and sends the problem information to a second base station controlling a cell where the radio network problem occurs.

First claim

1 . A base station comprising:
a receiving unit configured to receive, from a user equipment (UE), problem information about a radio network problem, with the radio network problem occurring on the UE in a cell controlled by another base station and after a radio resource control (RRC) connection has been reestablished or established between the UE and a cell controlled by the base station, wherein the problem information includes a field indicating that the radio network problem is a handover failure or a field indicating that the radio network problem is a radio link failure; and a transmitter configured to transmit the problem information to the another base station controlling the cell where the handover problem occurs.

2 . The base station of claim 1 , wherein the problem information includes signal quality of at least one of a source cell (S-Cell) or a target cell (T-Cell).

3 . The base station of claim 2 , wherein the signal quality includes at least one of reference signal received power (RSRP) or reference signal received quality (RSRQ).

4 . The base station of claim 1 , wherein the problem information includes identity information of a source cell (S-Cell) when the handover failure occurs, and the identity information of the S-Cell includes at least one of a frequency, a physical cell identity (PCI), a cell global identity (CGI), an IP, or a PLMN ID of the S-Cell.

5 . The base station of claim 1 , wherein the problem information includes identity information of a target cell (T-Cell) when the handover failure occurs, and the identity information of the T-Cell includes at least one of a frequency, a physical cell identity (PCI), a cell global identity (CGI), an IP, or a PLMN ID of the T-Cell.

6 . The base station of claim 1 , wherein the problem information includes identity information of a tracking area (TA) of a source cell (S-Cell) when the handover failure occurs.

7 . The base station of claim 1 , wherein the problem information includes identity information of the UE, and the identity information of the UE includes a cell-radio network temporary identity (C-RNTI) of the UE, a temporary mobile subscriber identity (TMSI) of the UE, or an international mobile subscriber identity (IMSI) of the UE.

8 . The base station of claim 1 , wherein the transmitter is configured to transmit the problem information to the another base station through an interface between the base station and the another base station or through transference of a mobility management entity (MME) in a core network, an element management system (EMS), or a network management system (NMS).

9 . A method for detecting a radio network problem, the method comprising:
receiving, by a first base station controlling a new cell that a radio resource control (RRC) connection has been reestablished or established with a user equipment (UE), problem information about a radio network problem occurs on the UE in a previous cell from the UE, after the RRC connection is established, wherein the problem information includes a field indicating that the radio network problem is a handover failure or a field indicating that the radio network problem is a radio link failure; and transmitting, by the first base station, the problem information to a second base station controlling the cell where the handover failure occurs, upon receiving the problem information from the UE.

10 . The method of claim 9 , wherein the problem information includes signal quality of at least one of the previous cell or the new cell.

11 . The method of claim 10 , wherein the signal quality includes at least one of reference signal received power (RSRP) or reference signal received quality (RSRQ).

12 . The method of claim 9 , wherein the problem information includes identity information of the previous cell when the radio network problem occurs, and the identity information of the previous cell includes at least one of a frequency, a physical cell identity (PCI), a cell global identity (CGI), an IP, or a PLMN ID of the previous cell.

13 . The method of claim 9 , wherein the problem information includes identity information of the new cell, and the identity information of the new cell includes at least one of a frequency, a physical cell identity (PCI), a cell global identity (CGI), an IP, or a PLMN ID of the T-Cell.

14 . The method of claim 9 , wherein the problem information includes identity information of a tracking area (TA) of a source cell (S-Cell) when the handover failure occurs.

15 . The method of claim 9 , wherein the problem information includes identity information of the UE, and the identity information of the UE includes a cell-radio network temporary identity (C-RNTI) of the UE, a temporary mobile subscriber identity (TMSI) of the UE, or an international mobile subscriber identity (IMSI) of the UE.

16 . The method of claim 9 , wherein in transmitting the problem information, the first base station transmits the problem information to the second base station through an interface between the first and second base stations; or through transference of a mobility management entity (MME) in a core network, an element management system (EMS), or a network management system (NMS).

17 . A computer readable storage medium, comprising computer program codes which when executed by a computer processor cause the compute processor to execute the steps of:
receiving, by a first base station controlling a cell that a radio resource control (RRC) connection is reestablished or established with a user equipment (UE), problem information about a radio network problem occurs on the UE in a cell from the UE, after the RRC connection is established, wherein the problem information includes a field carrying that the radio network problem is a handover failure or a field indicating that the radio network problem is a radio link failure; and transmitting, by the first base station, the problem information to a second base station controlling the cell where the handover failure occurs, upon receiving the problem information from the UE.

18 . The computer readable storage medium according to claim 17 , wherein the problem information includes signal quality of at least one of the previous cell or the new cell.

19 . The computer readable storage medium according to claim 18 , wherein the signal quality includes at least one of reference signal received power (RSRP) or reference signal received quality (RSRQ).

20 . The computer readable storage medium according to claim 17 , wherein the problem information includes at least one of identity information of the previous cell, identity information of the new cell, or identity information of the UE.
