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 system and method for application location register routing at a signal transfer point (26) are provided. The signal transfer point (26) includes processor clusters (64, 66, 68) and databases (236, 238) for processing queries including global title translation, local number portability, and application location register routing. A query message is received by the signal transfer point (26), a first database residing in the signal transfer point (26) is accessed to determine the location of a second database (238) also residing in the signal transfer point for processing the query message. The second database (238) is then accessed to obtain the network address of a home location register or short message service center, which is then used to deliver the query message to the network node specified by the network address.

A telecommunications system and method for managing Local Number Portability (LNP) querying for calls routed to Interexchange Carriers by providing a list of carriers in the Service Switching Point (SSP) (local service provider) for whom LNP querying is to be performed by the SSP. For example, calls destined to carriers on the list will be queried by the originating SSP, or other intermediate SSP, and calls destined for carriers not on the list will not be queried by the originating SSP, but instead will be directly routed to the carrier for LNP querying. Advantageously, the local service providers (SSPs) can perform LNP queries for calls destined to certain carriers and charge them for the queries. This will enable small long-distance carriers to provide competitive service in the network by purchasing the LNP querying facility from the SSPs. Furthermore, LNP querying will now be able to be provided for every call routed through an Interexchange Carrier (IXC), regardless of whether the IXC has LNP querying capability.

A telecommunication system includes: a first mobile switching center associated with a directory number, a local number portability data storage device in communication with the first mobile switching center, and a second mobile switching center in operative communication with the first mobile switching center and associated with wireless service to a mobile station. A subscriber associated with the mobile station has ported the directory number from the first mobile switching center to wireless service via another mobile switching center. In several embodiments, a method of relating the directory number to the mobile station for an incoming call is provided. The directory number is associated with a first mobile switching center and wireless service to the mobile station is associated with a second mobile switching center. Ultimately, in each embodiment of the method, the incoming call is forwarded from the first mobile switching center to another mobile switching center.

A method of provisioning a local number portability capable communication network which comprises numerous service provider networks, with updated signalling routing information to reflect a porting change is disclosed. A central administration center first updates the ported to network with updated signalling routing information. After the ported to network has been successfully updated the central administration center then proceeds to update all intermediate service provider networks. After confirmation has been received that all intermediate networks have been successfully updated the central administration center then proceeds to update the ported from network. Provisioning of networks which include intermediate networks supported by a central administration center in the predetermined manner and sequence disclosed can advantageously prevent signalling messages from looping between non-synchronized networks. The provisioning sequence works equally well where only two networks are involved, i.e. the ported from and ported to networks.

VoIP Routing Registry (VRR) has been created to allow VoIP Service Providers to direct calls properly over their IP networks. In operation, the VRR translates a 10-digit or 6-digit telephone number into a URI that can be used for routing. The VRR must also take into consideration Local Number Portability (LNP).

The invention provides a call method of local number portability service, a system thereof and a mobile switching center (MSC), and relates to the field of mobile communication. The invention aims atsolving the technical problem that the original number of a terminal is needed to be changed when the network of the terminal is transferred in the prior art. The call method of the local number portability service is used for calling a called terminal by a calling terminal, and the calling terminal has local number portability and is transferred into a second network scene from a first network; the method comprises: the MSC of a second network can acquire individual user number of the second network of the calling terminal from the calling terminal; the MSC of the second network searches individual user number of the first network corresponding to the individual user number of the second network of the calling terminal from a number portability data base (NPDB); and the individual user number of the first network is sent to the MSC of the called terminal by the MSC of the second network. The invention can be used for the local number portability service of a personal hand-phone system.

A method for collecting data to measure market-share for a defined telecommunication market. A market of interest is defined and a random panel of numbers is created. A call set-up is initiated to the created random panels by generating signaling messages wherein the signaling messages access a Calling Name Services (CNAM) database, a Local Number Portability (LNP) database, an E-911 Automated Location Information (ALI) database and a Line Information Database (LIDB) using signaling system 7 (SS7) protocol. Generated signaling messages access ENUM (Telephone Number Mapping) database and Internet Protocol (IP) Peering database using IP. The response to the generated signaling messages are used to determine assignment status, business ownership, businesses versus residential status and the technology employed for a given number in the created panel. In one embodiment, the process is repeated over a period in order to determine changes to the market-share and derivative metrics for the telecommunication market.

A system and method for determining a tariff for a real-time wireless service such as a prepaid service (PPS) for a wireless telephone call. A Local Number Portability Point (LNPP) provides an interface between service scripts in a Service Control Point (SCP) or application server, and an LNP database. When an Initial Detection Point (IDP) message is received by the service scripts, a query is sent through the LNPP to the LNP database to determine whether the call is made to or from a ported telephone number. If so, a routing number is returned. The scripts determine whether the routing number points to the network operator's own network or another, and notify a Service Data Point (SDP). If the routing number points to the operator's own network, the SDP applies a first tariff to the call. If the routing number points to another network, the SDP applies a second tariff.

A telecommunications system and method for managing Local Number Portability (LNP) querying for calls routed to Local Exchange Carriers by providing a list of carriers in the Service Switching Point (SSP) (local service provider) for whom LNP querying is to be performed by the SSP. For example, calls destined to carriers on the list will be queried by the originating SSP, or other intermediate SSP, and calls destined for carriers not on the list will not be queried by the originating SSP, but instead will be directly routed to the carrier for LNP querying. Advantageously, the local service providers (SSPs) can perform LNP queries for calls destined to certain carriers and charge them for the queries. This will enable small local exchange carriers to provide competitive service in the network by purchasing the LNP querying facility from the SSPs. Furthermore, LNP querying will now be able to be provided for every call routed through an Local Exchange Carrier (LEC), regardless of whether the LEC has LNP querying capability.

Systems and methods for a call flow for a mobile directory number (MDN) from a first phone to a second phone which has been intra-service ported. The system includes: a first switch of a first technology; a second switch of a second technology; and a local number portability database (LNP). The LNP stores local routing numbers (LRN) associated with the MDN. The WLNP system determines whether a call, from the first phone, is received by a public switched telephone network (PSTN) or the first switch. If the call is received by the PSTN with the LRN, the call is routed to the second switch based on the LRN. If the call is received by the first switch without the LRN, the first switch queries the LNP for the LRN and the call is routed intra-carrier to the second switch.

Systems and methods are disclosed for an embedded media terminal adapter (EMTA) that remotely switches telephony services from a telephone service provider to a telephony/cable service provider, which transmits telephony services via a coaxial cable network. The EMTA further enables local number portability (LNP) with very limited disruption to service. Switches that are responsive to command signals over the coaxial cable network are included in the EMTA. Upon release of service from the telephone service provider, the telephony/cable service provider transmits a command signal via the coaxial cable network to the EMTA, thereby remotely activating the switches. Subsequently, the EMTA receives telephony services from the telephony/cable service provider.

According to various embodiments of the present invention, systems and methods for local number portability in a telecommunication network are disclosed. An embodiment of a method includes placing a local number portability (LNP) order for the TN to be serviced by a core telecommunications carrier; and triggering the port of the TN via the core telecommunications carrier to occur prior to a time during which a typical port of the TN would have automatically occurred. A customer-initiated triggering may occur on a firm order commitment date associated with the LNP order. Other embodiments are also disclosed.

Methods are disclosed for identifying the carrier to which a phone, such as a mobile phone, subscribes in real time, at the time a call is originating from or terminating to the mobile phone. Where both parties to a call are subscribers to the same carrier, the methods can be used for applying preferential call rates to intra-carrier calls, e.g., making the calls free. The methods are particularly useful in the telephony networks with local number portability, in which the mere identification of the phone number does not necessarily identify the carrier to which the phone subscribes. The methods can use either existing databases to identify the carrier, such as LERG (Local Exchange Routing Guide) tables, number portability databases, name databases, and home location registers, or a new database can be created correlating mobile phone directory numbers with carriers.

A cross-connect switch (16) for implementing local number portability between a current local service provider originating switch (14) and a desired local service provider ported switch (18). The cross-connect switch (16) is connected in a line associated with a subscriber's directory number between the originating switch (14) and a main distribution frame (12) to establish a first active communication channel. The cross-connect switch (16) is also connected in-line between the ported switch (18) and the main distribution frame (12) to establish a second inactive communication channel. The cross-connect switch (16) is signaled to automatically deactivate the first communication channel and activate the second communication channel thereby routing communications associated with said subscriber's directory number to the ported switch (18).

When a subscriber calls into its Internet Service Provider (ISP), a central office receiving the call is triggered to perform a Local Number Portability (LNP) query. This LNP query is sent to an Intelligent Traffic Routing and Control (INTRAC) unit resident on a Service Control Point (SCP) which determines whether the call is to an ISP. If the call is to an ISP, the INTRAC unit polls a Remote Authentication Dial-In User Service (RADIUS) server to determine whether resources are available. The RADIUS server tracks the resources of the ISP and of other ISPs and informs the SCP of the available resources. The SCP then inserts the Local Routing Number (LRN) of the preferred resource into a reply that is sent to the central office. If resources are not available, the call is terminated before signaling occurs with any switch associated with the ISP. On the other hand, when resources are available, the subscriber can be directed to the preferred resource for the subscriber. The subscriber, for instance, can be directed to an access server within the ISP that has excess capacity or can be directed to an access server that provides the best service for the subscriber, whereby subscribers can be directed to X2 type service if they have an X2 modem or to K56Flex type service if they have a K56Flex modem. As another example, if one ISP is at maximum capacity, the subscriber can be directed to a second back-up ISP.

According to various embodiments of the present invention, systems and methods for local number portability in a telecommunication network are disclosed. An embodiment of a method includes submitting a local number portability (LNP) order for the TN directly to a first telecommunications carrier that the TN is to be transferred from, triggering a port of the TN in accordance with the LNP order, and porting the TN from the first telecommunications carrier to the second telecommunications carrier, wherein the second telecommunications carrier is bypassed by the customer during the submitting and the triggering of the LNP order. Other embodiments are also disclosed.

A mobile station is identified by a mobile directory number (MDN) and by a mobile station identifier (MSID). To communicate with a packet-switched network, the mobile station transmits its MSID, and a network access server, such as an interworking function (IWF), assigns an IP address to the mobile station and correlates the IP address with the MSID. A gateway receives a communication from the mobile station that includes the mobile station's IP address. The gateway identifies the mobile station's MDN based, at least in part, on the IP address, a correlation between IP address and MSID, and a correlation between MSID and MDN.
