Abstract

Disclosed are a method and an apparatus for transmitting and receiving measurement information in a mobile communication system. A terminal transmits a connection request message to a network and reports to the network, connection failure-related measurement information when a registered public land mobile network (RPLMN) included in a connection setup message received from the network corresponds to a pre-stored and selected public land mobile network (PLMN) and the connection failure-related measurement information stored with the selected PLMN is available.

Claims

1. A method for transmitting information by a user equipment (UE) in a wireless communication system, the method comprising:

transmitting, to a base station, a radio resource control (RRC) connection request message;

starting a timer based on the RRC connection request message;

if the timer expires, storing connection establishment failure information including an identity of a cell where connection establishment failure is detected; and

transmitting, to the base station, a RRC connection setup complete message including first information indicating the UE has the connection establishment failure information if the UE receives a RRC connection setup message and if a public land mobile network (PLMN) associated with the connection establishment failure information is equal to a registered PLMN.

2. The method of claim 1, wherein the timer is stopped if:

the UE receives the RRC connection setup message or a RRC connection reject message;

the UE performs a cell reselection;

or

an upper layers abort a RRC connection procedure.

3. The method of claim 1, further comprising:

receiving, from the base station, an UE information request message including second information indicating the base station requests the connection establishment failure information.

4. The method of claim 1, wherein the connection establishment failure information further comprises at least one of:

a reference signal received power (RSRP) and a reference signal received quality (RSRQ) of the cell where the connection establishment failure is detected;

a neighboring cell measurement report;

a location information of the UE;

or

a random access failure related information.

5. A method for receiving information by a base station in a wireless communication system, the method comprising:

receiving, from a user equipment (UE), a radio resource control (RRC) connection request message; and

receiving, from the UE, a RRC connection setup complete message including first information indicating the UE has connection establishment failure information if the base station transmits a RRC connection setup message and if a public land mobile network (PLMN) associated with the connection establishment failure information is equal to a registered PLMN,

wherein a timer is started based on the RRC connection request message and, if the timer expires, the connection establishment failure information, and

wherein the connection establishment failure information includes an identity of a cell where connection establishment failure is detected.

6. The method of claim 5, wherein the timer is stopped if:

the UE receives the RRC connection setup message or a RRC connection reject message;

the UE performs a cell reselection;

or

an upper layers abort a RRC connection procedure.

7. The method of claim 5, further comprising:

transmitting, to the UE, an UE information request message including second information indicating the base station requests the connection establishment failure information.

8. The method of claim 5, wherein the connection establishment failure information further comprises at least one of:

a reference signal received power (RSRP) and a reference signal received quality (RSRQ) of the cell where the connection establishment failure is detected;

a neighboring cell measurement report;

a location information of the UE;

or

a random access failure related information.

9. A user equipment (UE) for transmitting information in a wireless communication system, the UE comprising:

a transceiver; and

a controller coupled with the transceiver and configured to control to;

transmit, to a base station, a radio resource control (RRC) connection request message,

start a timer based on the RRC connection request message,

if the timer expires, store connection establishment failure information including an identity of a cell where connection establishment failure is detected, and

transmit, to the base station, a RRC connection setup complete message including first information indicating the UE has the connection establishment failure information if the UE receives a RRC connection setup message and if a public land mobile network (PLMN) associated with the connection establishment failure information is equal to a registered PLMN.

10. The UE of claim 9, wherein the timer is stopped if:

the UE receives the RRC connection setup message or a RRC connection reject message;

the UE performs a cell reselection;

or

an upper layers abort a RRC connection procedure.

11. The UE of claim 9, wherein the controller is further configured to control:

receiving, from the base station, an UE information request message including second information indicating the base station requests the connection establishment failure information.

12. The UE of claim 9, wherein the connection establishment failure information further comprises at least one of:

a reference signal received power (RSRP) and a reference signal received quality (RSRQ) of the cell where the connection establishment failure is detected;

a neighboring cell measurement report;

a location information of the UE;

or

a random access failure related information.

13. A base station for receiving information in a wireless communication system, the base station comprising:

a transceiver; and

a controller coupled with the transceiver and configured to control to;

receive, from a user equipment (UE), a radio resource control (RRC) connection request message, and

receive, from the UE, a RRC connection setup complete message including first information indicating the UE has connection establishment failure information if the base station transmits a RRC connection setup message and if a public land mobile network(PLMN) associated with the connection establishment failure information is equal to a registered PLMN,

wherein a timer is started based on the RRC connection request message and, if the timer expires, the connection establishment failure information, and

wherein the connection establishment failure information includes an identity of a cell where connection establishment failure is detected.

14. The base station of claim 13, wherein the timer is stopped if:

the UE receives the RRC connection setup message or a RRC connection reject message;

the UE performs a cell reselection;

or

an upper layers abort a RRC connection procedure.

15. The base station of claim 13, wherein the controller is further configured to transmit, to the UE, an UE information request message including second information indicating the base station requests the connection establishment failure information.

16. The base station of claim 13, wherein the connection establishment failure information further comprises at least one of:

a reference signal received power (RSRP) and a reference signal received quality (RSRQ) of the cell where the connection establishment failure is detected;

a neighboring cell measurement report;

a location information of the UE;

or

a random access failure related information.
