A first apparatus may determine that a DU function of a child IAB node is to transition between a first set of resources associated with an MT function of the child IAB node and a second set of resources associated with the DU function. The first apparatus may further configure a guard period associated with the transition time based on the first set of resources and based on the second set resources. A second apparatus determine to transition between a first set of resources associated with an MT function of the second apparatus and a second set of resources associated with a DU function of the second apparatus at a transition time. The second apparatus may further transmit, to a parent IAB apparatus, information requesting a guard period associated with the transition time based on the transition between the first set of resources and the second set resources.

A method, an apparatus, an electronic device, and a storage medium for network communication are provided. A first network entity sends a first request message to a second network entity. The first request message includes at least one piece of first network parameter type information, and is used to enable the second network entity to be triggered to send a first message to a third network entity according to a preset event. The first message includes at least one portion of network parameter information corresponding to the first network parameter type information. The first network entity receives a first reply message returned by the second network entity in response to the first request message. Using the present disclosure, the first network entity can dynamically manage an instantiation of the third network entity, and the authority of the third network entity to obtain network parameters.

In some implementations, a method includes receiving a connection request from a user application. A service request is sent to a radio resource control (RRC) module. An indication of failure of or a rejection to the service request due to access class barring is received from the RRC module. A retry of the user application connection request is prevented until expiration of an access-class-barring timer of the RRC module that resulted in the access class barring.

Apparatuses, methods, and systems are disclosed for session management function derived core network assisted radio access network parameters. One method includes receiving session management function derived core network assisted radio access network parameters from a session management function. The method includes storing the session management function derived core network assisted radio access network parameters in a protocol data unit session level context. The method includes using the session management function derived core network assisted radio access network parameters to determine an expected session activity behavior parameter set.

Described herein are techniques, devices, and systems for using an application server (AS) to trigger home subscriber server (HSS)-based proxy call session control function (P-CSCF) restoration for a user equipment (UE) in order to restore service to the UE via an in-service P-CSCF node. For example, an AS is configured to receive, from a serving CSCF (S-CSCF) node, an indication that a P-CSCF node assigned to a UE is unavailable, and, in response, the AS is configured to send, to a HSS, a request to initiate P-CSCF restoration for the UE. In turn, the HSS or a Unified Data Management (UDM) node is configured to send, to a control node, an indication to perform the P-CSCF restoration for the UE. The disclosed AS-triggered, HSS-based P-CSCF restoration procedure restores service to the UE.

A method of coordinating multiple instances of user plane traffic processing in a data network is described. The method includes the following steps: receiving control plane data from at least one basis station by a control plane of the data network, wherein the control plane data is associated with at least two subscribers connected to the at least one basis station; generating subscriber and user plane session data based on the received control plane data by a subscriber and session collector module, wherein the subscriber and user plane session data is associated with the at least two subscribers; selecting a user plane function instance out of a plurality of user plane function instances based on the subscriber and user plane session data by a load balancing module, wherein the selected user plane function instance is associated with exactly one subscriber; receiving user plane data from the at least one basis station, wherein the user plane data is associated with the at least two subscribers; and processing at least a portion of the user plane data by the selected user plane function instance. Further, a data network is described.

Accordingly embodiments herein achieve signaling method and system (2000) for provisioning signalling in an Integrated Access Backhaul (IAB) network (1000). The method includes providing a set of modifications in uplink and downlink signaling for an IAB node (100). The modifications either help to reduce the control channel payload or enable more flexible signaling of resources, improve efficient control channel scheduling and also avoid conflicts that might arise due to discrepancies between semi static and dynamic resource allocation.

An integrated access and backhaul (IAB) node may receive a parent knowledge message, the parent knowledge message indicating whether a parent IAB node of the child IAB node has received an optional signaling message, determining to transition between first resources and second resources at a transition time, the first resources being associated with use of a mobile termination of the child IAB node, the second resources being associated with use of the distributed unit of the child IAB node, and determine a number of guard symbols provided by the parent IAB node at the transition time based on whether the parent knowledge message indicates that the parent IAB node has received the optional signaling message.
