data interconnections are managed in a mobile communications network having multiple packet control function entities and multiple packet data serving nodes , wherein each pcf and pdsn communicates signaling messages according to a mobile signaling protocol . information for a mobile subscriber is received . the ms is associated with a same one of the pdsns when the ms moves from a first area covered by a first pcf to a second area covered by a second pcf . it is determined that a first pcf has issued a first connection request on behalf of an ms . as a result of the first connection request , a selection protocol is executed a first time to select a pdsn that corresponds to the ms . it is determined that a second pcf has issued a second connection request on behalf of the ms . the selection protocol is executed a second time to select the same pdsn that was selected as a result of the first connection request .
