Abstract
When a network pages the temporary user mobile identifier of a mobile station the mobile station sends a response to the network. Next the network checks the authenticity of the user using a ciphering key corresponding to the temporary user mobile identifier and a random number. If the temporary user mobile identifier is authenticated a normal incoming call acceptance procedure is executed. If the mobile station is authenticated although the temporary user mobile identifier is wrong the network reassigns a new temporary user mobile identifier to the mobile station and stops the current communication. In communication the network and the mobile station mutually notify encipherment-onset time and negotiate about encipherment manner with each other. In addition diversity handover is commenced upon a call attempt. Furthermore if a branch replacement is necessary the current branch is replaced by new branches capable of executing the diversity handover. Additionally when a new call occurs to or from the mobile station capable of treating a plurality of calls simultaneously the mobile station uses the same branch structure and the same communication frequency band for all of calls. Additionally when a new call occurs to or from the mobile station capable of treating a plurality of calls simultaneously a branch structure and a communication frequency band which can continue all of the calls are selected and used. Therefore the mobile communications system is suitable for transmission of various sorts of data in accordance with the development of multimedia.

Claim
1. A diversity handover controller communicating with a mobile terminal through a plurality of base stations, comprising:
a call attempt receiver configured to receive via one of the plurality of base stations a call attempt from the mobile terminal having no access link established with any of the plurality of base stations;
a handover setup requester configured to initiate a handover setup procedure by sending a handover setup request among the plurality of base stations;
a confirmation sender configured to send an acknowledgement to the handover set up request from one or more base stations which have completed the handover setup procedure;
a branch information reporter configured to send the mobile station branch information regarding more than one base station among the plurality of base stations which is accessible to establish an access link with the mobile terminal for a diversity handover.', 'a call attempt receiver configured to receive via one of the plurality of base stations a call attempt from the mobile terminal having no access link established with any of the plurality of base stations;', 'a handover setup requester configured to initiate a handover setup procedure by sending a handover setup request among the plurality of base stations;', 'a confirmation sender configured to send an acknowledgement to the handover set up request from one or more base stations which have completed the handover setup procedure;', 'a branch information reporter configured to send the mobile station branch information regarding more than one base station among the plurality of base stations which is accessible to establish an access link with the mobile terminal for a diversity handover.
2. A diversity handover controller according to claim 1, wherein the plurality of base stations are functional entities.
3. A diversity handover controller according to claim 1, wherein the call attempt is associated with a pilot report of strong pilot signals.
4. A diversity handover controller according to claim 3, wherein the handover setup requester sends the handover setup request to one or more base stations, using the pilot report.
5. A diversity handover controller according to claim 4, wherein the handover setup requester sends the handover setup request to the one or more base stations identified in the pilot report.
6. A diversity handover controller according to claim 1, wherein the handover setup requester sends the handover setup request from the one of the plurality of base stations.
7. A diversity handover controller according to claim 1, wherein the branch information comprises a request to establish an access link with the more than one base station for the diversity handover.
8. A diversity handover controller according to claim 7, wherein the branch information reporter sends the branch information from the one of the plurality of base stations.
9. A diversity handover controller according to claim 8, further comprising a sync signal receiver configured to receive a sync signal for establishing an access link from the mobile terminal, which has received the branch information
10. A diversity handover controller according to claim 9, further comprising a setup completion reporter configured to send an acknowledgement of completing establishment of access link
11. A diversity handover method implemented in a diversity handover controller communicating with a mobile terminal through a plurality of base stations, comprising:
receiving a call attempt via one of the plurality of base stations from the mobile terminal having no access link established with any of the plurality of base stations;
initiating a handover setup procedure by sending a handover setup request among the plurality of base stations;
sending an acknowledgement to the handover set up request from one or more base stations which have completed the handover setup procedure; and
sending the mobile station branch information regarding more than one base station among the plurality of base stations which is accessible to establish an access link with the mobile terminal for a diversity handover.', 'receiving a call attempt via one of the plurality of base stations from the mobile terminal having no access link established with any of the plurality of base stations;', 'initiating a handover setup procedure by sending a handover setup request among the plurality of base stations;', 'sending an acknowledgement to the handover set up request from one or more base stations which have completed the handover setup procedure; and', 'sending the mobile station branch information regarding more than one base station among the plurality of base stations which is accessible to establish an access link with the mobile terminal for a diversity handover
12. A method according to claim 11, wherein the plurality of base stations are functional entities
13. A method according to claim 11, wherein the call attempt is associated with a pilot report of strong pilots signals
14. A method according to claim 13, wherein sending a handover setup request comprises sending a handover setup request to one or more base stations, using the pilot report
15. A method according to claim 14, wherein sending a handover setup request comprises sending a handover setup request to one or more base stations identified in the pilot report
16. A method according to claim 11, wherein sending a handover setup request comprises sending a handover setup request from the one of the plurality of base stations
17. A method according to claim 11, wherein the branch information comprises a request to establish an access link with the more than one base station for the diversity handover
18. A method according to claim 17, wherein sending branch information comprises sending branch information from the one of the plurality of base stations
19. A method according to claim 18, further comprising receiving a sync signal for establishment of a radio access link from the mobile terminal, which has received the branch information.
20. A method according to claim 19, further comprising sending an acknowledgement of completing establishment of radio access link.']
