Abstract: A method and apparatus for session management function reselection. A method performed by an access and mobility function includes selecting a second session management function (SMF) to serve a session of a user equipment (UE). The session of the UE is currently served by a first SMF and an access network. The method further includes sending a create session management context request comprising a reason of selecting the second SMF to serve the session of the UE to the second SMF. The reason indicates that the session of the UE is still served by the access network. The method further includes receiving a create session management context response comprising a session resource modify request from the second SMF. The session resource modify request includes access network tunnel information of the access network. The method further includes sending the session resource modify request to the access network.

A method performed by a control plane function may comprise: receiving, from a terminal device, a request for assigning a network address prefix; determining whether the network address prefix is assigned by the control plane function or a user plane function; transmitting, to the user plane function, a PFCP Session Modification Request for requesting the user plane function to assign the network address prefix, if it is determined that the network address prefix is assigned by the user plane function; receiving, from the user plane function, a PFCP Session Modification Response including an assigned network address prefix; and transmitting the assigned network address prefix to the terminal device. The specific procedure for the terminal device to obtain the network address prefix from a network entity not directly requested by the terminal device may be defined.

Abstract: Disclosed in the present invention is a differentiable method for mining constant rules. On the basis of defining constant operators and path operators according to a knowledge graph, a fusion attention mechanism is used to evaluate relations passed by rules by using attention values. Meanwhile, attentions are calculated by aggregating surrounding attributes and the corresponding attribute values for tail node of each hop respectively. Attentions of the attributes are used to enhance selection of relations in the rules to achieve link prediction. According to generated model parameters, high quality symbolic rules are output by parameter analysis and statistics. This method is particularly suitable for application scenarios with complex reasoning requirements that require high prediction accuracy, provide interpretations for predictions, and need to precipitate reasoning rules.

Abstract: A VPD sensor for a horticultural environment is provided. The VPD sensor includes an upper housing, a lower housing, and a vapor pressure deficit sensing module. The lower housing is coupled with the upper housing and includes a lower sidewall and a bottom wall that cooperate to define an interior.
