A method for optimized routing of service based interface (SBI) request messages to remote network function (NF) repository functions (NRFs) using indirect communications via a service communications proxy (SCP) includes, at an SCP including at least one processor, receiving an SBI request message. The method further includes forwarding the SBI request message to a remote NRF. The method further includes determining that the remote NRF is unable to process the SBI request message, and, in response to determining that the remote NRF is unable, identifying a georedundant mate of the remote NRF. The method further includes forwarding the SBI request message to the georedundant mate NRF of the remote NRF that is unable to process the SBI request message.

Method for operating a network node of a wireless digital data network based on broadcast layer-2 periodic frames, wherein said network is composed by a plurality of network nodes, wherein each network node is either a mobile node equipped with an on-board unit (OBU) node, or is a static node equipped with a road-side unit (RSU) node, said method comprising a current network node of the plurality of network nodes carrying out the following steps: periodically broadcasting a Network Status Information (NSI) frame which comprises: the node identifier and a type of node of the current network node; receiving broadcasted NSI frames from neighbouring network nodes of the plurality of network nodes reachable by the current network node through wireless communication; for any one received NSI frame, storing the received NSI frame in an entry in a NSI table (NSIT) if the received NSI frame was the first received NSI frame from a neighbouring network node, or otherwise, if the received NSI frame was not the first received NSI frame from the neighbouring network node, updating a previously stored NSIT entry with the received NSI frame; marking as expired or deleting any previously entered NSIT entry after a predetermined period of time has passed after receiving or updating said any previously entered NSIT entry. Also an electronic network node of a wireless digital data network, wherein said network node is programmed to carry out the method.

A communication device of handling a network feature comprises a storage unit for storing instructions and a processing circuit coupled to the storage unit. The processing circuit is configured to execute the instructions stored in the storage unit. The instructions comprise receiving system information indicating whether an Evolved Packet System (EPS) optimization is supported and a first Non Access Stratum (NAS) message indicating whether the EPS optimization is supported; determining to use the EPS optimization, when the system information indicates that the EPS optimization is not supported and the first NAS message indicates that the EPS optimization is supported; and determining not to use the EPS optimization, when the system information indicates that the EPS optimization is supported and the first NAS message indicates that the EPS optimization is not supported.

The present invention relates to the field of network communication technologies, and discloses a method, a device, and a system for establishing an on-demand route. The method includes: determining that a stable route needs to be established; establishing the stable route and recording a route entry corresponding to the stable route in a route table; determining an effective time of the stable route, in which the effective time of the stable route is longer than the effective time of another common route; and performing an aging operation on the route entry according to the effective time of the stable route. With the present invention, requirements of different applications on the delay may be satisfied, and the consumption of the network bandwidth may be reduced.

The invention relates to a proxy node comprising means for managing a proxy table,

a receiver for receiving a message from a first resource restricted device, said message being intended to at least one corresponding destination device, control means for checking whether an entry for the first resource restricted device is included in the set of entries of the proxy table, the set of entries of the proxy table indicating the set of resource-restricted devices the proxy node is in charge of,

a transmitter for forwarding the message depending on the result of the proxy table checking, the means for managing the proxy table being arranged for cleaning the proxy table of the entry relative to the resource-restricted device by monitoring the relative usage of the proxy node for forwarding messages for the resource restricted device with the usage of competitor proxy nodes for forwarding messages for the resource restricted device.

Techniques for routing in communications networks include determining a state of a destination node in a current routing table stored at a first node. A value for a reference cost to the destination node is determined based on a minimum cost to the destination in the current routing table. Based on the state, a request message is formed including a reference distance field to prevent loops, an originating node field, a destination field, and a previous hop field. The request message is sent to a different second node within range. A record that indicates the data in the request message is stored in a pending request table. A reply message is received in response to sending the request message. In response to receiving the reply message, the record in the pending request table is removed, and the current routing table is updated based on the reply message.

A server system receives an indication of a media content item from a device and determines a first set of values that correspond to characteristics of the indicated content item. The server system analyzes a defined set of content items to identify a proxy media content item. The identified proxy media content item has a second set of values that meets similarity criteria for the first set of values. The server system determines, based on analysis of a plurality of sets of media content items, a result set of one or more media content items that are related to the proxy media content item. The server system provides information associated with the result set of media content items to the device of the user.

The method includes generating, from the defined set of media content items, a result set of media content items that are associated with the proxy media content item. The method also includes determining a result set of users of the media content provider associated with the result set of media content items and transmitting, to the device of the user, information associated with the result set of users of the media content provider.

Handling supplementary services offered in association with Internet Protocol multimedia services based on particular policies is described. In an example, server(s) can receive, from a first user device, a policy associated with handling one or more communications directed to a particular identifier. The server(s) can subsequently receive a communication from a second user device, the communication being associated with a header identifying the particular identifier as the intended recipient of the communication. The server(s) can determine whether the policy is to be applied to the communication and, based at least partly on determining that the policy is to be applied to the communication, the server(s) can update the header based at least in part on the policy. The server(s) can transmit the communication based at least in part on the header, thereby transmitting the communication pursuant to the policy.
