Abstract

A wireless communication system includes a base station that receives information regarding neighboring wireless systems and updates and stores this information for use in handover of user equipments (UEs).

Claims

1. A method for updating a system database of a base station based on information sent by a user equipment (UE) using a first radio access technology, the method comprising:

Receiving a first information packet at the base station from the UE, wherein the first information packet comprises detection of an adjacent base station that uses a second radio access technology;

the base station communicating with the adjacent base station to validate the first information packet received from the UE;

updating the system database in the base station with the first information received from the UE wherein the information comprises detection of the system;

adjusting base station coverage based on the first information received from the UE;

transmitting a second information packet regarding the adjacent base station to the UE;

the base station authenticating an identity of the UE; and

the base station receiving an encrypted message, responsive to the authentication, from the UE.

2. The method of claim 1, further comprising:

the base station receiving traffic loading information from the UE; and

the base station updating the system database to include traffic loading information.

3. The method of claim 1 wherein the first information packet comprises signal power levels of the neighboring system.

4. The method of claim 1 further comprising the base station receiving geo-location information together with a message authentication code.

5. The method of claim 1 further comprising the base station communicating with the adjacent base station at regular intervals.

6. The method of claim 1 further comprising the base station communicating with the adjacent base station based on a time trigger.
