An example technique includes identifying, from an AF that implements a ML model, a request related to reservation of resources for a plurality of AF sessions, wherein the plurality of AF sessions relate to respective UEs of a plurality of UEs, and wherein the request includes an indication of addresses of respective UEs of the plurality of UEs and a QoS parameter; transmitting, to a BSF of the cellular network, a discovery request related to discovery of respective PCFs that are serving the respective UEs of the plurality of UEs; identifying, based on the discovery request, a discovery response that includes indications of the PCFs; identifying, based on the indications of the PCFs and the QoS parameter, a result related to the reservation of resources; and transmitting, to the AF, an indication of the result. Other embodiments may be described and/or claimed.

A system to support time sensitive networking (TSN) in a 5G system is described. The TSN application function (AF) sends to a device-side translator a Port Management Information Container (PMIC) and port number that has a Stream Identification type value and Stream Identification controlling parameters that depend on the Stream Identification type value for per-stream policing and filtering in a distributed bridge. During establishment of the bridge, the network-side translator port numbers are provided to the TSN AF in a Bridge Management Information Container (BMIC). Any PDU session of the bridge is able to be selected for Ethernet port and Bridge management procedures between the network-side translator and the TSN AF.

5G time sensitive networking bridge configuration

An apparatus and system for a multiple universal subscriber identity module (MUSIM) user equipment (UE) are described. Due to activity on another USIM, the MUSIM UE transmits a service request message to release an N1 non-access stratum (NAS) signaling connection or reject a paging request received from the network, dependent on whether the MUSIM UE is in a 5generation (5G) Mobility Management (5GMM)-CONNECTED mode or a 5GMM-IDLE mode. The service request message may contain a paging restriction that restrict paging to: all paging, all paging except for paging for voice service, all paging except for packet data unit (PDU) session(s), and all paging except for voice service and PDU session(s).

Musim UE connection release, paging restriction and rejection

This disclosure describes systems, methods, and devices related to service function chaining in wireless networks. A communications system may include a communication control function to select one or multiple communication service functions associated with establishing service function chaining (SFC) services for telecommunications; a service orchestration and chaining function (SOCF) to establish the SFC services; and a service orchestration exposure function (SOEF) to expose the SFC services to an application function (AF) of the system.

Enhanced service function chaining in next generation cellular networks

In some embodiments, during the SIP registration, the UE indicates in the REGISTER requests its support for ANBR as defined by 'ANBR' attribute in the SDP and the P-CSCF indicates its support for the “ANBR” attribute in the SDP in the response for registration. In some embodiments, the P-CSCF serving a PLMN passes through the “ANBR” attribute in the SDP when the P-CSCF recognizes that the PLMN supports ANBR functionality. In some embodiments, the UE can include “ANBR” attribute in the SDP offer and answers when the P-CSCF indicates its support for the “ANBR” attribute in the SDP.

Apparatus and method for Session Initiated Protocol (SIP) registration procedure for access network bitrate recommendation (ANBR) capability signaling

An apparatus and system to enable dynamic offloading and execution of compute tasks are described. In split CU-DU RAN architectures, the CU-CP is connected with multiple compute control functions (CF) and service functions (SF) that have different computing hardware/software capabilities. Different architectures depend on whether the SF is collocated with the CU-UP, the CU-UP and SF only serve compute messages, a compute message is supplied directly to the CU-UP or also traverses the CU-CP. In response to reception from a UE of a compute message containing data for computation being sent to the CU-CP through the DU, the CU-CP sends the data to the SF with identifiers and sends the result to the UE.

Computing workload transport over control plane in next generation cellular networks

Methods, systems, and storage media are described for providing codec mode notification (CMN) messages for speech to be signaled from a sender to a receiver. Other embodiments may be described and/or claimed.

Signaling codec mode notifications for multimedia telephony sessions

In some embodiments, during the SIP registration, the UE indicates in the REGISTER requests its support for ANBR as defined by 'ANBR' attribute in the SDP and the P-CSCF indicates its support for the 'ANBR' attribute in the SDP in the response for registration. In some embodiments, the P-CSCF serving a PLMN passes through the &#x201c;ANBR&#x201d; attribute in the SDP when the P-CSCF recognizes that the PLMN supports ANBR functionality. In some embodiments, the UE can include &#x201c;ANBR&#x201d; attribute in the SDP offer and answers when the P-CSCF indicates its support for the &#x201c;ANBR&#x201d; attribute in the SDP.

Apparatus and method for session initiated protocol (SIP) registration procedure for access network bitrate recommendation (ANBR) capability signaling

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.

Techniques for indicating the presence of critical data at user equipment (UE) in an Radio Access Network (RAN) are described. According to various such techniques, a UE can identify critical data and send an information element including an indication of the critical data to a node (NB) of the RAN. The NB can then modify a schedule or handling the data communicated between the UE and the NB.
