This disclosure provides a method, apparatus, and computer-readable medium for wireless communication at a modem, comprising receiving, via an interface with a host, an internet protocol (IP) packet including a first transport protocol header and a first IP header. The IP packet has a size greater than a maximum transport unit (MTU) size allowable for each packet transmitted over a communication link. The modem segments the IP packet into a plurality of segments based on a segment size indicated by a segmentation policy. Each segment includes a respective derived segment transport protocol header and a respective derived segment IP header derived from the IP packet. Each of these derived headers includes at least one field based on the segmentation policy, and each of the segment transport protocol headers includes a checksum for the respective segment. Additionally, the modem transmits the plurality of segments over the communication link.

Example implementations include a method, apparatus, and computer-readable medium comprising receiving, by a multi-capability device from a control panel, a message configured according to a protocol that defines a packet format configurable to indicate each queried capability of the multi-capability device; transmitting, responsive to the message querying a single capability of the multi-capability device, a second message from the multi-capability device to the control panel, wherein the second message includes a packet configured according to the packet format to include a state or data value for the single capability of the device; and transmitting, responsive to the message querying at least two capabilities of the multi-capability device, a third message from the multi-capability device to the control panel, wherein the third message includes a packet configured according to the packet format to include one state or data value for each one of the at least two capabilities of the device.

A first node (110; 210; 212; 310; 1000) for determining an indication of a maximum datagram size supported without fragmentation in communication between the first node (110; 210; 212; 310; 1000) and a second node (111; 211; 210; 220) in an Internet Protocol, IP, network (100; 201; 201-202; 300). The first node (110; 210; 212; 310; 1000): sends (301; 901), to the second node (111; 211; 210; 220), request messages in varying sized IP packets using an application layer protocol over UDP and which datagrams are configured not to be fragmented; receives (302; 902) response messages from the second node, each indicating a received request message that the response message is in response to, was received by the second node (111; 211; 210; 220); identifies (303; 903) a request message for which there is a change in receipt of response message compared to another request message of said varying sized IP packets; determines (304; 904), based on said identification, an indication of the maximum datagram size supported without fragmentation.

In a system and a method for providing authentication for Rich Communication Services (RCS) application on a user equipment (UE), a Proxy Call Session Control Function (P-CSCF) of the IMS receives a SIP REGISTER request message sent from an IMS Session Initiation Protocol (SIP) client on the UE as part of an authentication of the IMS SIP client. A Serving Call Session Control Function (S-CSCF) of the IMS or a registration service performs an Authentication and Key Agreement (AKA) challenge with the IMS SIP client as part of the authentication. A Home Subscriber Server (HSS) of the IMS or a Unified Data Management (UDM) function provides, upon successful authentication of the IMS SIP client, an initial authorization grant for the IMS SIP client. The RCS application, after obtaining the initial authorization grant, registers for RCS service with the RCS network, via RCS Application Programming Interface Gateway (API GW).

A machine-implemented method for use at a destination node for transferring data from a source node, the method comprising: establishing one or more connections with the source node; sending to the source node a request for a data stream, the request including control information to be applied at the source node, the control information including a number of degrees of freedom (DoFs) or frames to be transmitted across each of the one or more connections; and receiving one or more coded frames through the data stream over the one or more connections.

A terminal device may be configured to receive support information from a communication device by using a first wireless connection which has been established between the terminal device and the communication device. The support information may indicate whether the communication device supports a predetermined scheme. The terminal device may be configured to, in a case where the support information indicates that the communication device supports the predetermined scheme, execute a first control process for executing wireless communication in conformity with the predetermined scheme between the terminal device and the communication device. The terminal device may be configured to, in a case where the support information indicates that the communication device does not support the predetermined scheme, execute a second control process for executing wireless communication in conformity with a different scheme different from the predetermined scheme between the terminal device and the communication device.

Provided herein are apparatus and method for signal RAN-assisted codec adaptation capabilities via IMS. An apparatus for a UE includes a RF interface to receive an SDP offer message from the remote UE, the SDP offer message including a first dedicated SDP attribute parameter to indicate support of ANBR capability of the remote UE; and processor circuitry. The processor circuitry is to decode the SDP offer message to determine the support of ANBR capability of the remote UE; encode an SDP answer message in response to the SDP offer message, the SDP answer message including a second dedicated SDP attribute parameter to indicate support of ANBR capability of the UE; and cause transmission of the SDP answer message to the remote UE. Other embodiments may also be disclosed and claimed.

Versions of a service not reachable by a set of service requestors that use the service are removed. Multiple, different versions of a service are stored, along with metadata associated with the multiple, different versions of the service. The metadata is examined to determine one or more of the multiple, different versions of the service that are not reachable by the set of service requestors that use the service. Those versions are deleted.
