    Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for resource allocation and scheduling within a wireless communication system.
    SOLUTION: During resource allocation, maximum total system transmission power (P), a maximum number of codes available (N), a maximum number of codes for each user in the system (N*=(N
    1 , ..., N
    d )), a maximum SINR value for each user in the system (S*=(S
    1 , ..., S
    d )), and a SINR per watt of transmission power for each user in the system (e*=(e
    1 , ..., e
    d )) are received by a scheduler (201). The scheduler then outputs (215) an optimal number of codes per user (n*) and an optimal power level per user (p*). (Here, the asterisk of the items above denotes a maximum value of the amount on the left of the asterisk.).

    Abstract: A method and apparatus for handing over a mobile station (106) from a serving base station (104a) to a target base station (104b) within a wireless communication system (100) is described. A session is established between the mobile station and the serving base station and it is determined that the mobile station is to be handed over from the serving base station to the target base station. The target base station notifies the serving base station of identifying data of the target base station and added to the identifying data is a message to be sent to mobile station regarding the handover of the mobile station. The serving base station sends the message including the identifying data to the mobile station and the mobile station is handed over from the serving base station to the target base station using the identifying data of the target base station.

    Abstract translation: 描述了一种用于在无线通信系统（100）内将移动台（106）从服务基站（104a）移交到目标基站（104b）的方法和装置。 在移动台和服务基站之间建立会话，并且确定移动台将从服务基站切换到目标基站。 目标基站向服务基站通知目标基站的识别数据，并且添加到识别数据中的是要向移动台发送关于移动台的切换的消息。 服务基站使用目标基站的识别数据将包含识别数据的消息发送到移动站，并且移动站从服务基站切换到目标基站。

    Abstract: A first base station communicates (102) with a second base station (wherein an ongoing communication cannot be handed over from the first base station to the second base station and wherein the first and second base station each employ, at least in part, a same set of carrier resources) to prevent interference by usage of the second base station with a user of the first base station. By one approach, this activity can be based, at least in part, upon receipt (101) of a message from an end user platform indicating that a carrier resource that is presently being used by the end user platform is being interfered with by the second base station. By another approach, this activity can take place prior to any actual such interference.

    Abstract: An indication is received from the mobile station (114) indicating that the mobile station (114) is moving from an originating mobility agent (106) to a destination mobility agent (108). An identity of the destination mobility agent (108) is determined using the indication. Routing information is sent from the originating mobility agent (106) to the destination mobility agent (108) using the identity. Incoming data is routed to the mobile station (114) using the routing information.

    Abstract: A wireless access point (102) detects an indicia of a change in wireless connectivity of a mobile station (101) with respect to itself and another wireless access point (103). The wireless access point then automatically effects at least one of establishing a communication between itself and the second wireless access point regarding the change in wireless connectivity and establishing a temporary data tunnel as between itself and the second wireless access point. These network elements can also act to automatically establish a data flow path for the mobile station between the second wireless access point and a network element (such as a mobility management agent (105)) that is external to the common subnet. In a preferred approach this comprises, at least in part, automatically sending a registration request to the network element other than in response to a specific request from the mobile station to send such a registration request.
