摘要： An apparatus and method of configuring a number of retransmissions for an automatic repeat request (ARQ) scheme (e.g., hybrid ARQ) includes configuring one or more first maximum retransmission numbers based on respective one or more first predetermined values and independent of a second maximum retransmission number. The first maximum retransmission numbers may indicate a maximum number of retransmissions related to respective service flows operational with the base station. The second maximum retransmission number may indicate a maximum number of retransmissions related to control messages transmitted in the wireless network, and may be configured based on a second predetermined value. The configuration of the first maximum retransmission numbers may include the maximum retransmissions numbers associated with a specific user in communication with the base station. Further, at least one of the first maximum retransmission numbers of a particular user may be reconfigured to a third predetermined value.

摘要： The present invention relates to systems and methods for establishing a data-path between a mobile station and a home access service network gateway (“ASN-GW”). During the authentication process, a visited ASN-GW receives a first message that identifies a home ASN-GW associated with the mobile station. After the mobile station has been authenticated, the visited ASN-GW receives a first data-path request message from a base station serving the mobile station, requesting a path for data-packet communication for the mobile station that extends between base station and the visited ASN-GW. The visited ASN-GW responsively uses the received identification to send a second data-path request message to the home ASN-GW which requests a path for data-packet communication that extends between the base station and the home ASN-GW. Once the data-path has been established, the home ASN-GW may monitor and/or place restrictions on the data being transmitted to and from the mobile stations.
