摘要： In a CDMA cellular telecommunications system, comprising mobile exchanges (MSC), base stations (BS) and mobile stations (MS), a new CDMA handoff procedure, a semi-hard handoff, is employed. Semi-hard handoff takes place within one and the same border base station (BS12), located in the boundary of two service areas (SA1, SA2) which are controlled by neighbouring mobile exchanges (MSC1, MSC2). This border base station is connected to and can be accessed from both of these neighbouring mobile exchanges. The inventive semi-hard handoff is a network based handoff of the communication control functions from the first to the second neighbouring mobile exchange without interrupting the active CDMA radio communications between the border base station (BS12) and the mobile station (MS).

摘要： A soft handoff in a cellular telecommunications system in which a user mobile station (30) relays user communication radio signals via at least two base stations (BS) to and from a controlling mobile exchange (MSC) connected to another system user. The relay of user information signals is performed by using digital frames carried on digital transmission connections (70-76, 80-86) in the uplink and downlink direction. The differential delay of the two or more terrestrial routes between the base stations and the exchange is compensated by a novel time alignement (TA) procedure. Each of the base stations sends time aligment request to the mobile exchange which performs the frame time alignement of the downlink transmissions by taking into account TA requests from all base stations.
