摘要： A mobility event is supported on a flat or next generation mobile data networks with data breakout or offload at the edge of the mobile data network. Packet data is buffered while a complete set of the PDP context information is transferred from the source eNodeB to the target eNodeB and the mobile core network is updated with the information about the handover in a timely manner to prevent packet loss and thus provide a seamless user experience. The breakout system supports the PDP context transfer by shifting the end point of the TCP communication from the local breakout entity (MIOP@eNodeB) to the core breakout entity (MIOP@GW), transferring the TCP connection to the core breakout entity, and supporting the network initiated control flows in a way that is seamless from the perspective of the UE and the core network.

摘要： A method and system supports subscriber based IP data breakout at the edge of a mobile data network without monitoring the use of security keys or breaking into ciphered message exchanges. The system employs a first service mechanism operating at the edge of the mobile data network a second service mechanism operating at the core on the S11 interface. The second service mechanism at the core collects subscriber related data, subscriber identifiers and tunnel identifiers and sends this data to the first service mechanism. The second service mechanism at the core collects subscriber related data, subscriber identifiers and tunnel identifiers and sends this data to the first service mechanism. The first service mechanism uses the tunnel identifiers received from the second service mechanism to identify sessions and tunnels carrying subscriber dependent data packets (S1-U packets) in order to perform subscriber-based IP data breakout, offloading and optimization.

摘要： A flow setup table in a basestation breakout component allows for servicing non-cacheable IP data flows at the breakout component without the need for network address translation. For each broken out IP flow at the breakout component, the flow setup table holds a mapping between tunnel IDs and the IP related information. The flow setup table data is sent to the breakout component at the gateway. The gateway breakout component uses the flow setup table to forward non-cacheable data requests to the internet and return data received from the internet back to the basestation breakout component. The basestation component then sends the non-cacheable data in the correct tunnel to the user equipment requesting the data.

摘要： Mobile network services are performed at the edge in a flat mobile data network in a way that is transparent to most of the existing equipment in the mobile data network to reduce the load and increase efficiency on the mobile data network by breaking out data at the edge based on specific IP data flows. The mobile data network includes a radio access network and a core network. A first service mechanism in the radio access network breaks out data coming from a basestation based on breakout conditions, and performs one or more mobile network services. The second service mechanism determines what traffic satisfies breakout authorization criteria and informs the first service mechanism. The message from the second service mechanism triggers the first service mechanism to perform IP flow based breakout. An overlay network allows the first and second mechanisms to communicate with each other.

摘要： A mobile data network includes a radio access network and a core network. A first service mechanism in the radio access network breaks out data coming from a basestation. When data is broken out by the first service mechanism, the data is delivered at the edge, which means the true activity of the channel is not visible to the core network. In order to maintain the high-speed channel, channel maintenance data packets are sent to and from the radio network controller on the network tunnel. The maintenance channel is also used to send cache miss data to a subscriber when a cache miss occurs at the edge of the mobile data network, without regard to a need for channel maintenance data packets.

摘要： Push based services are supported on a breakout system in a mobile data network. The breakout system may not breakout some push based services and simply pass through these services to user equipment. In a PDP context with a dynamic IP address, the communication with the user equipment may be broken out and then be placed in a preserved state. In this situation, a breakout system which is not an active entity in the signaling over the mobile data network can not establish communication with the user equipment to send down the push data. To establish a new communication connection with the user equipment with a PDP context in a preserved state, a paging request from the mobile network is initiated to trigger a service request from the user equipment. The breakout system can then use the newly established connection to push the data to the user equipment.

摘要： A system and method provides seamless switchover of a user device (UE) between a mobile data network and a wireless network while providing policy and charging control (PCC) of the data session in the mobile data network. A mobile core network component is made ASF aware to process user data traffic related to an auto switching function (ASF) server from a UE client located on the UE using a special access point name (APN). The mobile core network component then uses a dedicated deep packet inspection (ASF DPI) for all data transfers to the special APN. The core network component is then able to process the UE data traffic seamlessly as the traffic is toggled between the ASF tunnel the WiFi tunnel. By monitoring the data traffic on the ASF tunnel, the core component (GGSN/PGW) is able to provide PCC for the data session.

摘要： A breakout system initiates radio link control (RLC) resets to resynchronize data communication to improve quality of experience for the user. Synchronization of radio traffic is monitored and maintained by the breakout system. When data is broken out, the RLC function is split into two different flows, between the user equipment (UE) and the breakout system and between the breakout system and the radio network controller (RNC). When the sequence numbers of the two flows become out of sync the ciphering context will become out of synchronization resulting in errors. The breakout system can initiate an RLC reset into both of these flows to resynchronize the data communication to improve user's quality of experience.
