Abstract

A method and an apparatus for managing User Equipment (UE) history information are provided. The method for managing user equipment history information in a wireless communication network includes determining if a recording event occurs when the user equipment enters into an idle mode; recording information about the recording event in idle mode user equipment history information when the recording event occurs; and transmitting the recorded idle mode user equipment history information to a base station when the user equipment accesses the base station.

Claims

1. A method for managing user equipment history information in a wireless communication network, the method comprising the steps of:

determining if a recording event occurs, when the user equipment enters into an idle mode;

recording information related to the recording event into idle mode user equipment history information, when the recording event occurs; and

transmitting the recorded idle mode user equipment history information to a base station, when the user equipment accesses the base station.

2. The method of claim 1, wherein a recording event comprises at least one of an idle mode conversion event, a cell change event, a service non-available event, and a cell re-selection event.

3. The method of claim 1, wherein recording information comprises recording event information including at least one of an occurrence event, an ID of a cell selected by the user equipment and related information, Public Land Mobile Network (PLMN) information selected by the user equipment, a time influenced by each event, a time camped in a corresponding cell, and measuring information into the idle mode user equipment history information.

4. The method of claim 1, wherein transmitting the recorded idle mode user equipment history information further comprises:

receiving a transmission request for the idle mode user equipment history information from the accessed base station; and

transmitting the idle mode user equipment history information to the base station according to the reception of the transmission request.

5. The method of claim 1, further comprising transmitting the idle mode user equipment history information to a neighbor base station or to a core network entity.

6. An apparatus for managing user equipment history information in a wireless communication network, the apparatus comprising:

a user equipment history information generator configured to determine if a recording event occurs when the user equipment enters into an idle mode, and to record information related to the recording event in idle mode user equipment history information when the recording event occurs;

a storage unit configured to store the recorded idle mode user equipment history information; and

a user equipment history information transmitting controller configured to transmit the recorded idle mode user equipment history information to a base station when the user equipment accesses the base station.

7. The apparatus of claim 6, wherein the recording event comprises at least one of an idle mode conversion event, a cell change event, a service non-available event, and a cell re-selection event.

8. The apparatus of claim 6, wherein the idle mode user equipment history information comprises at least one of an occurrence event, an ID of a cell selected by the user equipment and related information, Public Land Mobile Network (PLMN) information selected by the user equipment, a time influenced by each event, a time camped in a corresponding cell, and measuring information.

9. The apparatus of claim 6, wherein the user equipment history information transmitting controller controls transmission of the idle mode user equipment history information to the base station, when a transmission request for the idle mode user equipment history information is received from the base station.

10. The apparatus of claim 6, wherein the idle mode user equipment history information is shared with a neighbor base station or with a core network entity.
