Abstract: A system and method are provided for reliable activation and attachment of mobile devices. An activation server receives, from a client device, a subscription request for accessing a network, wherein the subscription request includes a first identifier of the client device. The activation server determines, based on the first identifier, whether a pending subscription account exists or a new subscription account is to be created. Upon determining that the pending subscription account exists or the new subscription account is to be created, the activation server releases the pending subscription account or creates the new subscription account, and instructs the client device to remove a second identifier from the client device and to use the first identifier for attaching to the network.

Abstract: Disclosed techniques limit or reduce the amount of data for which a subscriber may be charged that may not actually be received at the subscriber's mobile device. A counter may be started when a node has data to be delivered to a mobile device. The node may send the data through a radio access network for delivery to the mobile device and record an amount of the data sent for the mobile device through the radio access network for data usage billing purposes while running the counter, until the counter reaches a predetermined value. When the counter reaches the predetermined value, if no traffic channel has been set up with the mobile device, the node will stop recording the amount of the data sent for the mobile device through the radio access network for data usage billing purposes.

Abstract: A server device may store inter-layer quality of service (“QoS”) information, indicating a set of link layer QoS levels that are associated with a particular device, a set of network layer QoS levels that are associated with the set of link layer QoS levels, and a set of MPLS QoS levels that are associated with the set of link layer QoS levels. A network device may establish a set of bearers, that correspond to the set of link layer QoS levels, with a particular device; output information regarding the set of network layer QoS levels that are associated with the set of link layer QoS levels, to allow the particular device to select a bearer, of the set of bearers, via which to output traffic to the network device; receive, from the particular device, traffic via the bearer; and determine a particular MPLS QoS level associated with the received traffic.

Abstract: A device associated with a Voice over IP (VoIP) network receives a call from a mobile device. The device determines whether a sector identifier (ID) associated with the call includes a femtocell identifier. The device further determines a location identifier included in the sector ID when the sector ID includes the femtocell identifier. The device also identifies a recipient of the call based on the location identifier and forwards the call to the recipient.
