| 摘要 |
The present invention relates to an arrangement (<bold>1</highlight>) and a method in a cellular communication system supporting packet data communication. The arrangement is connected to a number of base stations (BS) and communicates with the base stations over a first communication protocol (<bold>11</highlight>). The arrangement further communicates with the data network over a third protocol (<bold>13</highlight>) and it comprises a processing arrangement (<bold>100</highlight>) managing packet data communication for a number of mobile subscriber stations (<bold>6</highlight>) communicating with the base stations. The processing arrangement (<bold>100</highlight>) at least comprises a number of first processing means (<bold>10,20</highlight>) and a number of second processing means (<bold>30,40,50</highlight>). Each first processing means (<bold>10,20</highlight>) communicates with a number of the base stations and terminates the first communication protocol (<bold>11</highlight>). The second processing means (<bold>30,40,50</highlight>) manage the mobile subscriber stations (<bold>6</highlight>) and each second processing means (<bold>20,30,40</highlight>) contain mobile subscriber station information for a number of mobile subscriber stations. Each mobile subscriber station that it registered with the arrangement is assigned to one of the second processing means (<bold>30;40;50</highlight>) and the first processing means (<bold>10,20</highlight>) are provided with information about the load status of the second processing means (<bold>30,40,50</highlight>). The first processing means (<bold>10,20</highlight>) use said information to assign mobile subscriber stations not actually registered with the arrangement (<bold>1</highlight>) to one of the second processing means (<bold>30,40,50</highlight>). |
