An admission control and load balancing system controls admission of packet streams or calls to a network and balances the packet traffic across the network, improving quality of service. The system includes a central database which stores information including cost data associated with individual paths and links across the network. A processor, in communication with the database, coordinates the admission control and load balancing decisions, and updates of the database cost data to reflect the dynamic network conditions, based on input from appropriate data sources. In one embodiment, referred to as the exact algorithm, the database is consulted by the admission control points or gatekeepers prior to admitting each arriving packet stream, and the database contents are updated call-by-call to reflect the allocation of resources to each admitted stream. In another embodiment, referred to as the inexact algorithm, control decision as well as database updates occur on a periodic rather than on a call-by-call basis to promote better scalability. In this embodiment, the processor periodically calculates admission decisions based on cost data in the central database. These admission decisions are then periodically forwarded to a satellite database associated with each gatekeeper, for storage and use in admission decisions until the next update epoch.

A method and system for creating a virtual roaming solution for a MSISDN using a softphone over an IP network. The system involves (i) implementation of a novel virtual mobile network (VMN) comprising virtual visitor location register (vVLR), virtual home location register (vHLR) and virtual multiple switching centre (vMSC) on an IP server responsible for managing IP call traffic administration, and (ii) implementation of a novel mobile to internet gateway (MIG) comprising an VoIP gateway for diverting call traffic from the mobile network to the IP network, and an IP server with vMSC functionality to translate routing information from the VMN to GSM network so as to appear to the GSM network as a traditional mobile operator. The system dynamically registers the subscriber to the IP network, and provides valid routing information to the MSC (Mobile Switching Centre) or public telephone switch to route the call over to the NGN (next generation network) operator in the IP space.

A signaling regimen between a mobile station MS, a radio node RN, and a packet data switching node PDSN enables a quality parameter to be applied to packets moving between a mobile and a CDMA2000 network. The MS creates a new flow for packets of a certain data type and sends a related quality parameter for that flow to the BS. The BS determines whether an existing or new service instance will carry the new flow, and obtains authorization for the service instance to meet the quality parameter from the PDSN. The BS or PDSN builds a map between flow and a policy that ensures the quality is met, and the map is used to place different packets into the appropriate flow and service instance. Policies and enforcement may differ on uplink and downlink.

In one embodiment, techniques provide QoS-aware service flow mapping in an access network. A message is received from an access device at a gateway in the access network. The message includes a traffic flow specification. The traffic flow specification may include packet filter information, which is used to install a packet filter to route traffic to the access device. The gateway creates a session and associates the packet filter with it. When an incoming packet is received at the network device, the packet is matched to the packet filter. The incoming packet is then sent to the access device for the session. The traffic flow specification may also specify QoS parameters that are desired. The QoS parameters may then be applied to the packet sent to the access device. The gateway and access device may negotiate to determine a QoS to apply.

The invention discloses a method for implementing signaling link redundancy in IP networks. Two ASPs are created for the same AS in the host at the IP network side, and all user adaptation protocols share ASPSM and ASPTM messages so that the states of the two ASPs can become active and inactive respectively, thus to implement two signaling links for serving the same traffic. When switch is initiated, SCTP association can be closed by using “graceful close”, and the SCTP itself will make sure to send out all the data remaining in its buffer and its higher-layer applications will also send subsequent data in order after learning the remaining data are all sent out, thus sequential delivery for the data can be guaranteed. This method can avoid data loss and disorder, and the speed for switch can be ensured because the backup link will be notified immediately after the data on the primary link are sent out.

A method for processing a signal and a bearer separately in an ALL IP network system includes the steps of: transmitting a service request message (SRM) from a mobile station (MS) to a radio network (RN); at the RN, determining whether a circuit related service or a packet related service is requested; if the circuit related service is requested: (i) transmitting a CM service request message to a MSC server, (ii) receiving a service request acknowledgement (SRA) message from the MSC server, and (iii) assigning a bearer in response to the SRA message; and if the packet-related service is requested: (i) transmitting the (SRM) from the RN to a core network without processing the SRM; (ii) at the core network, processing the SRM and transmitting an assignment request to the RN, the assignment request requesting that the RN assign the bearer; and (iii) assigning the bearer in response to the assignment request.

In cellular and broadband wireless networks, specific nodes are assigned to handle functions such as radio resource management (BSC / BTS), session management (PDSN / GGSN / Access Gateways) and service switching (MSC, CSCFs). The function to guarantee Quality of Service, or QOS, is typically associated with the service being implemented and assigned to the one or more nodes implementing the service. There are also policy definition and control nodes (PDFs) identified within the standards. These manage static service level agreements that provide instructions to QOS mechanisms on different nodes within the network. With a move toward an all IP network and a services model with continuously changing requirements (such as user / terminal mobility, varying RF conditions), static QOS mechanisms become inadequate and the need for a dynamic and adaptive QOS mechanism becomes significant.

Session flows between a client (1) and a server (2) are pinned through a receiving interworking unit (7) and a transmitting interworking unit (11) connected via the non-IP based communications path (9). The receiving interworking unit (7) and transmitting interworking unit (11) are then configured to convert received data between IP and a non-IP based communications protocols. Subsequently, when the transmitting interworking unit (11) receives IP protocol based data for the client (1) from the server (2) the data is converted and transmitted via the non-IP based communications link to the receiving interworking unit (7). Upon receipt, the receiving interworking unit (7) converts the data back into an IP-protocol based format and forwards the converted data on to the client (1). The disclosed approach enables the client (1), to receive a regular IP packet stream from the server (2), where: one segment (9) of the path between server (2) and client (1) transports the data in a non-IP format; and neither IP client (1) nor the server (2) is aware of the non IP segment and no change in their all IP network mode of operation is required.
