Multi-channel support for virtual private networks in a packet to ATM cell cable system

A two-way cable network offering high-speed broadband communications delivered via virtual private networks over a multi-channel shared media system. Bi-directional transmission of packet to ATM cell based communications is established between a head end communication controller and a number of subscriber terminal units, whereby individual cells are prioritized and routed according to a virtual connection. Virtual connections are organized to support multiple virtual private networks in a shared media CATV system. The virtual private network to which a particular STU belongs is user selectable and has the flexibility of handling multi up/downstream channels with different MAC domains. The present invention can also handle non-ATM MAC domains via the same common ATM switch. To overcome the limited number of addresses inherent to common ATM switches, a mapping/remapping function is implemented in the port cards. Furthermore, downstream as well as upstream traffic are filtered at each STU. In one embodiment, information pertaining to downstream traffic is used to implement predictive scheduling in order to improve the timing associated with the request/grant cycle. In another embodiment, a user has the ability to select a quality of service that best suits the needs of the current application. In a further embodiment, the scheduling function is associated with each of the receivers in order to provide improved scalability.

Channel detection notification method, channel detection notification system and base stations

The invention provides a channel detection notification method, a channel detection notification system and base stations used when an LTE system works at an unauthorized frequency band. The channel detection notification method includes the steps that the primary cell base station receives RRM measuring results, reported by a terminal, of multiple base stations at the unauthorized frequency band; according to the RRM measuring results of the base stations, the secondary cell base station is selected for the terminal; if it is determined that downlink traffic reaches a set first traffic threshold value, the secondary cell base station is informed to conduct downlink channel detection; if it is determined that uplink traffic reaches a set second traffic threshold value, the secondary cell base station and/or the terminal are/is informed to conduct uplink channel detection. According to the channel detection notification method, channel detection work conducted when the LTE system works at the unauthorized frequency band is managed by the primary cell base station in a united mode, the time delay generated when the secondary cell base station and/or the terminal carry/carries out channel detection can be effectively shortened, accuracy at which channel detection time is judged can be improved, and the resource utilization rate is increased when the LTE system works at the unauthorized frequency band.

RRGS-round-robin greedy scheduling for input/output terabit switches

A novel protocol for scheduling of packets in high-speed cell based switches is provided. The switch is assumed to use a logical cross-bar fabric with input buffers. The scheduler may be used in optical as well as electronic switches with terabit capacity. The proposed round-robin greedy scheduling (RRGS) achieves optimal scheduling at terabit throughput, using a pipeline technique. The pipeline approach avoids the need for internal speedup of the switching fabric to achieve high utilization. A method for determining a time slot in a NxN crossbar switch for a round robin greedy scheduling protocol, comprising N logical queues corresponding to N output ports, the input for the protocol being a state of all the input-output queues, output of the protocol being a schedule, the method comprising: choosing input corresponding to i=(constant-k-1)mod N, stopping if there are no more inputs, otherwise choosing the next input in a round robin fashion determined by i=(i+1)mod N; choosing an output j such that a pair (i,j) to a set C={(i,j)| there is at least one packet from I to j}, if the pair (i,j) exists; removing i from a set of inputs and repeating the steps if the pair (i,j) does not exist; removing i from the set of inputs and j from a set of outputs; and adding the pair (i,j) to the schedule and repeating the steps.

A fast handover method of a td-lte communication system based on target cell pre-carrying

Aiming at the requirements of frequent cell handover, short handover time and high handover success rate in high-speed railway TD-LTE communication system, a fast handover method of TD-LTE communication system based on target cell pre-carrying is proposed. According to the train's running position, speed and direction, after the network planning is completed, a list of neighboring cells is generated in advance, and the switching position of each switching zone is preset, that is, the longitude and latitude position information. Before the train enters the overlapping area of ​​switching between two cells , when the distance from entering the handover zone is a certain value L, the source base station eNodeB determines and sends the pre-bearer information to the target base station eNodeB according to the measurement report of the user terminal UE, and the target base station eNodeB performs the evolution packet system ( Evolved Packet System (EPS) resources to bear the load, when the train enters the handover zone, if the train meets the handover criteria, the train will be handed over from the source cell to the target cell. Therefore, this method reduces the handover delay and is beneficial to improve the handover success rate. The method can dynamically adjust the switching method according to the mobile speed of the UE, solve the problem of fast switching in a high-speed mobile environment, reduce the number of communication drops, improve the success rate of switching, enhance the service quality of high-speed broadband mobile services, and promote high-speed railway trains. The development of domestic multimedia broadband mobile Internet services meets the growing needs of passengers for mobile communication services.
