摘要： The present invention provides a method involving a femtocell in communication with an Internet Protocol Multimedia Subsystem (IMS) network. In one embodiment, the femtocell operates according to code division multiple access (CDMA) standards. The method includes receiving, from the femtocell and at a first secure entity in the IMS network, first authentication information generated by the mobile unit using a first random number broadcast by the femtocell in a global challenge. The method also includes receiving, from a second secure entity in the secure network, at least one security key formed based on the global challenge and second authentication information for uniquely challenging the mobile unit. In one embodiment, the second secure entity is a CDMA-based authentication server. The method further includes providing the security key(s) to the femtocell in response to authenticating the mobile unit based upon the second authentication information.

摘要： In an H-ARQ system, when the AN is receiving packet data traffic on the RL from an AT and is generating ACKs and NAKs according to the ability of the AN to properly decode such data, the AN gates-off a DRCLock bit within in a sub-packet duration in which an ACK is transmitted on the FL MAC channel. When it receives an ACK, the AT ignores the non-transmitted DRCLock bit in a current sub-packet duration, and assumes that the DRC channel is “good”. When the AN sends a NAK to the AT, it also sends the DRCLock bit. When the AT receives a NAK in a sub-packet duration, it reads and processes whatever DRCLock bit is received during that sub-packet duration. When no data traffic is transmitted on the RL traffic channel, corresponding DRCLock bits are not gated-off by the AN and are transmitted to the AT. The AT then processes the received DRCLock bits. In an alternative embodiment, transmission of DRCLock is totally eliminated.
摘要翻译：在H-ARQ系统中，当AN正在从AT接收RL上的分组数据流量时，根据AN对这些数据进行正确解码的能力产生ACK和NAK，AN将关闭一个DRCLock位在FL MAC信道上发送ACK的子分组持续时间。当接收到ACK时，AT忽略当前子包持续时间内未发送的DRCLock位，并假定DRC信道为“良好”。当AN向AT发送NAK时，它还发送DRCLock位。当AT在子分组持续时间内接收到NAK时，它读取并处理在该子分组持续时间期间接收的任何DRCLock比特。当在RL业务信道上没有传输数据业务时，相应的DRCLock比特不被AN门控，并被发送给AT。 AT然后处理接收到的DRCLock位。在替代实施例中，完全消除了DRCLock的传输。
