Claims
- 1. A mobile station of a mobile communication system including the mobile station, a base station connected to the mobile station, and a switching center connected to the base station, wherein
said mobile station notifies said switching center of information on one or more addition branch candidates between said mobile station and said base station, and of information indicative of precedence of said addition branch candidates.
- 2. The mobile station as claimed in claim 1, wherein
said mobile station notifies, while communicating with said base station using a maximum number of radio branches simultaneously establishable, said switching center of addition of said addition branch candidates, when precedence of an addition branch candidate to be added exceeds, by an amount of a predetermined threshold value, precedence of a communicating branch with lowest precedence.
- 3. The mobile communication system as claimed in claim 2, wherein
information transmitted from said mobile station to said switching center further includes information on one or more communicating branches between said mobile station and said base station.
- 4. The mobile communication system as claimed in claim 1, wherein
information transmitted from said mobile station to said switching center further includes information on one or more communicating branches between said mobile station and said base station.
- 5. A mobile station of a mobile communication system comprising the mobile station, a base station connected to the mobile station, and a switching center connected to the base station, wherein
information transmitted from said mobile station to said switching center includes information on one or more deletion branch candidates between said mobile station and said base station.
- 6. A diversity handover branch control method, in which a mobile station detects one or more addition branch candidates constituting handover candidates in communications between said mobile station and a base station connected to the mobile station, and notifies a switching center connected to the base station of the addition branch candidates, wherein
information transmitted from said mobile station to said switching center includes information on one or more addition branch candidates between said mobile station and said base station, and information indicative of precedence of said addition branch candidates.
- 7. The diversity handover branch control method as claimed in claim 6, wherein
said information transmitted from said mobile station to said switching center further includes information on one or more communicating branches between said mobile station and said base station.
- 8. The diversity handover branch control method as claimed in claim 6, wherein said information indicative of precedence is an order of arrangement of information on said addition branch candidates.
- 9. The diversity handover branch control method as claimed in claim 8, wherein said order of arrangement is a decreasing order of transmission losses.
- 10. The diversity handover branch control method as claimed in claim 6, wherein said information indicative of precedence consists of numerals representing information on said addition branch candidates.
- 11. The diversity handover branch control method as claimed in claim 6, wherein said information indicative of precedence is an order of arrangement of information on said communicating branches and information on said addition branch candidates.
- 12. The diversity handover branch control method as claimed in claim 11, wherein said order of arrangement is a decreasing order of transmission losses.
- 13. The diversity handover branch control method as claimed in claim 6, wherein said information indicative of precedence consists of numerals representing information on said communicating branches and information on said addition branch candidates.
- 14. A diversity handover branch control method as claimed in claim 6, wherein said switching center establishes said communication branches between said mobile station and said switching center using information on one or more communicating branches between said mobile station and said base station, transmitted information on said one or more addition branch candidates, and information indicative of precedence of said addition branch candidates.
- 15. The diversity handover branch control method as claimed in claim 14, wherein
said switching center establishes, when a sum total of a number of communicating branches and a number of the addition branch candidates exceeds a maximum radio branch number simultaneously establishable in communications between said mobile station and said base station, a communication branch in order of precedence up to a maximum cable branch number that can be processed simultaneously by said switching center.
- 16. The diversity handover branch control method as claimed in claim 15, wherein said maximum cable branch number is greater than said maximum radio branch number by N, where N is an integer equal to or greater than one.
- 17. The diversity handover branch control method as claimed in claim 15, wherein
said mobile station makes a decision of said addition branch candidates again and notifies said switching center of said addition branch candidates, when a total sum of a communicating branch number and an addition branch number exceeds said maximum cable branch number, and hence said addition branch candidates are not added because of restrictions on an upper limit of said maximum cable branch number.
- 18. The diversity handover branch control method as claimed in claim 17, wherein
said switching center stores, when said addition branch candidates are not added because of the upper limit of said maximum cable branch number, branch candidates that cannot be added because of the upper limit of said maximum cable branch number, and autonomously carries out control.
- 19. A diversity handover branch control method in a mobile communication system including a mobile station, a base station connected to the mobile station, and a switching center connected to the base station, wherein
information transmitted from said mobile station to said switching center includes information on one or more deletion branch candidates between said mobile station and said base station.
- 20. A diversity handover branch control method in a mobile communication system including a mobile station, a base station connected to the mobile station, and a switching center connected to the base station, wherein
said mobile station autonomously creates settings for deleting one or more communication branches.
- 21. A diversity handover branch control method, in which a mobile station detects one or more communication branches constituting handover candidates, and notifies a switching center of the communication branches, wherein
said mobile station autonomously deletes one or more communication branches, and subsequently notifies said switching center of the deleted branches via a remaining communication branch.
- 22. A diversity handover branch control method, in which a mobile station detects one or more communication branches constituting handover candidates, wherein
said mobile station autonomously deletes one or more communication branches, and subsequently a switching center, which is connected with said mobile station through a base station, deletes a corresponding cable branches by detecting disconnection of the radio branch.
- 23. A diversity handover branch control method, in which a mobile station detects one or more addition branch candidates constituting handover candidates in communications between said mobile station and a base station connected to the mobile station, and notifies a switching center connected to the base station of the addition branch candidates, wherein
said mobile station does not notify, when a communicating branch number equals a simultaneously establishable maximum radio branch number between said mobile station and said base station, said switching center of information on addition branch candidates that are unlikely to be added in diversity handover.
- 24. A diversity handover branch control method, in which a mobile station detects one or more addition branch candidates constituting handover candidates in communications between said mobile station and a base station connected to the mobile station, and notifies a switching center connected to the base station of the addition branch candidates, wherein
said mobile station notifies, when a sum total of a communicating branch number and an addition branch candidate number is equal to or less than a simultaneously establishable maximum radio branch number between said mobile station and said base station, said switching center of said addition branch candidates.
