A method for obtaining segment routing over Internet Protocol version 6 data plane (SRv6) tunnel information of Internet Protocol version 6 segment routing, including sending, by a first network device, a request packet to a second network device, where the request packet is used to request to detect reachability of an SRv6 tunnel and obtain SRv6 tunnel information of the second network device, and the second network device is a network device on the SRv6 tunnel, receiving, by the first network device, a response packet from the second network device, where the response packet includes the SRv6 tunnel information of the second network device, and obtaining, by the first network device, the SRv6 tunnel information of the second network device based on the response packet.

Some embodiments relate to methods and systems for initiating and transferring cellular subscription service using associated cellular communication devices. Cellular service may be initiated for a first cellular communication device via a second cellular communication device. The first cellular communication device may be provisioned to operate in an independent mode. In other scenarios, cellular service may be transferred from the first cellular communication device operating in independent mode to a third cellular communication device, which may be provisioned to operate in independent mode.

A method and system for the leveraging a reserved relationship number by an SLS platform and/or SLS phone module for the purpose of performing special operations other than making an SLS call available for termination at a subscriber TD and/or a third party TD involve associating the SLS phone number of the subscriber, the primary number of the subscriber and a next set of instructions via a common reserved relationship number.

A method and a call routing system (CRS) are provided for routing an incoming call made to one of multiple numbers of a user to a call receiving client application (CRCA) deployed on one or more user devices when the called number is not reachable. The CRS, in communication with the CRCA deployed on one or more user devices, sets up a user account using one or more of the user's multiple numbers. The CRS detects availability of the CRCA on one or more user devices over a data network to accept an incoming call. The CRS receives the incoming call made to one of the numbers, when the called number is not reachable. The CRS routes the incoming call to the CRCA on one or more user devices over the data network on detecting the availability of the CRCA on one or more user devices over the data network.

A method of provisioning wireless communication service to wireless communication devices. The method comprises allocating telephone numbers to a first plurality of devices, allocating the same telephone numbers to a second plurality of devices, transmitting an eSIM provisioning data bundle in a short message service (SMS) message to the first plurality of devices by a first communication network routing node based on the corresponding one of the plurality of telephone numbers, transmitting an eSIM provisioning data bundle in a SMS message to the second plurality of devices by a second communication network routing node based on the corresponding one of the plurality of telephone numbers, wherein the first communication network routing node routes SMS messages in a first region and the second communication network routine node routes SMS messages in a second region, whereby a single telephone number is leveraged by two different devices located in different regions.

A number management unit (11) of a number management system (1) generates a transaction using number portability information including a telephone number and encrypted connection destination information, newly generates a block using multiple transactions, approves the generated block, and stores the block in a number database (13) as a blockchain. A number resolution unit (12) searches transactions in the blockchain using a telephone number that is a query target as a key, extracts and decrypts the encrypted connection destination information corresponding to the query telephone number, and sends the connection destination information corresponding to the query telephone number as a response.

An integrated GW (I-GW) can be utilized to facilitate communications with Internet of things (IoT) devices that operate without Internet protocol (IP) addresses, based on assigned preferences and/or priority. In one aspect, the I-GW can efficiently deliver existing services for various types of IoT devices (e.g., that support different non-IP protocols) and can create emerging applications across different vertical applications. Further, the I-GW can leverage mobility network elements to authenticate, prioritize connections, and/or enable data orchestration via underlying software defined network (SDN)-enabled capabilities and/or infrastructure services. By utilizing IoT devices that do not have IP stacks, a cost and/or size of the IoT devices can be decreased and battery life can be significantly extended.

A method and a call routing system (CRS) are provided for routing an incoming call made to one of multiple numbers of a user to a call receiving client application (CRCA) deployed on one or more user devices when the called number is not reachable. The CRS, in communication with the CRCA deployed on one or more user devices, sets up a user account using one or more of the user's multiple numbers. The CRS detects availability of the CRCA on one or more user devices over a data network to accept an incoming call. The CRS receives the incoming call made to one of the numbers, when the called number is not reachable. The CRS routes the incoming call to the CRCA on one or more user devices over the data network on detecting the availability of the CRCA on one or more user devices over the data network.

Aspects of the subject disclosure may include, for example, receiving, from a private telephone number mapping server, a first database comprising address records associated with subscriber devices of a first carrier, storing, at an inter-carrier server system, an inter-carrier mapping database comprising the address records converted to an inter-carrier format, receiving new address records associated with new subscriber devices registered with the first carrier, updating the inter-carrier mapping database with the address records converted to the inter-carrier format, receiving a first query for an address record associated with a called number of a first device of the first carrier for initiating an internet protocol call between the first device and a second device of the second carrier, querying the inter-carrier mapping database of the inter-carrier server system for the address record, and transmitting the address record to the second carrier for routing the internet protocol call. Other embodiments are disclosed.
