An information transmission method includes: receiving, by a network element selector from a user equipment (UE), a first message including identification information of the UE; determining, based on the identification information of the UE, a user group to which the UE belongs; determining a controller corresponding to the user group; and receiving and sending a further message to the controller.

Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE) capable of establishing a split bearer involving at least primary and secondary radio link control (RLC) entities. The techniques generally include deciding, based on one or more conditions, whether to submit a Packet Data Convergence Protocol (PDCP) protocol data unit (PDU) to the primary RLC entity or the secondary RLC entity according to one or more rules and submitting the PDCP PDU to at least one of the primary or secondary RLC entities in accordance with the decision.

A method, apparatus and computer program product are provided for the efficient distribution of tunneled packets associated with multiple pieces of user equipment across central processing unit cores associated with network components. Example implementations contemplate one or more network components, such as a NodeB or gateway, which are configured with multiple IP addresses associated with multiple cores or other processors within the network component. In such example implementations, tunnels may be initialized to network endpoints such that network traffic loads imposed on the network component can be balanced by selecting one or more IP addresses from amongst the plurality of IP addresses associated with the particular network component.

The disclosure concerns a method and communication system for user path (UP) reselection. The method includes sending, from a network entity, a request to influence UP path reselection, the request indicating an application function (AF) location to be included in the UP path reselection. The method further includes generating, by a policy control function (PCF), a policy associated with the request and providing, by the PCF, the policy to a session management function (SMF). The method additionally includes performing, by the SMF, the UP path reselection for a session according to the policy and acknowledging, by the PCF, the request to the network entity.

A system and method for dynamically switching transmission of selected data from cellular core network to unidirectional point-to-multipoint downlink network or from unidirectional point-to-multipoint downlink network to cellular core network based on traffic flow analysis is provided. The system includes a cellular packet core 206, a broadcast offload packet core (BO-PC) 302, and a load manager 202. The cellular packet core 206 controls a cellular radio access network (RAN) 412 for providing bidirectional connectivity to a converged user equipment (UE) (204) to transmit or receive selected data through the cellular packet core 206 and the RAN 412. The BO-PC 302 controls a broadcast radio access network (RAN). The broadcast radio access network (RAN) includes at least one Broadcast Radio Head (BRH) 322 for providing unidirectional downlink path to the converged user equipment (UE) 204 to receive selected data through the at least one Broadcast Radio Heads (BRH) 322.

Provided are a method and a device for load information interaction, a processor and a storage medium. The method includes: sending, by a first network node, a load request message to a second network node, where the load request message is used for indicating configuration information used by the second network node in reporting load information to the first network node; and receiving, by the first network node, the load information reported by the second network node according to the configuration information. The second network node and the first network node belong to different logical nodes in a network. The technical problem that load management cannot be performed when the second network node and the first network node belong to different logical nodes in related technology is solved, and the maximum performance of the network is fully exhibited.

Various embodiments herein provide techniques for integrated access and backhaul (IAB) nodes. For example, embodiments include techniques associated with: rate-proportional routing for network coding; utilizing multiple routes in IAB networks; user equipment (UE) and parent selection for efficient topology in IAB networks; establishing efficient IAB topologies; and/or adaptive coded-forwarding for network coding. Other embodiments may be described and claimed.

When a packet data session is established for a user equipment (UE), a comparative assessment of load information factors from different sets of load information factors associated with a plurality of user plane function (UPF) instances may be performed. Each set of load information factors of a UPF instance may include predicted load information factors indicative of a predicted load at the UPF instance. A UPF instance may be selected for the packet data session of the UE based on the comparative assessment. The comparative assessment may additionally consider a predicted load contribution of the packet data session to be established for the UE. A data analytics function may utilize a model (e.g. a multiple linear regression model) to calculate predicted load contribution factors, where the model is derived based on historical usage data from previous sessions of one or more UEs, for example, data from charging data records (CDRs).

A method of providing user level mobility load balancing is provided, the method comprising: classifying a group of User Equipments (UEs) in a cell into multidimensional planes based on metrics associated with the UEs; defining thresholds for each dimension; using the defined thresholds determining to discard or select certain planes of a dimension and the UEs contained in the planes; and identifying a best UE of the UEs contained in selected planes for offload.
