Abstract: A communication method comprises that if a policy control device does not support setup of an Internet Protocol (IP) multimedia subsystem (IMS) default bearer during setup of an IMS default bearer for a terminal, the control plane gateway sends second indication information to a user plane gateway, where the second indication information indicates the control plane gateway bypasses the policy control device. When the user plane gateway receives an IMS session request from the terminal and determines that the control plane gateway bypasses the policy control device, the user plane gateway sends first indication information to the control plane gateway, and the first indication information indicates the control plane gateway to send, to the policy control device, a first request to request to establish a mapping relationship between the terminal and the control plane gateway such that an IMS session can be set up between terminals.

Abstract: To avoid hash table collisions, such as in response to sequential addresses, a hash module is provided that includes a first multiplexer that, responsive to a control signal, outputs received data on one of two or more scramblers. The scramblers are configured to selectively receive the selected data output from the first multiplexer and perform a scrambler operation on the selected data to generate scrambled data. A second multiplexer outputs the scrambled data to a first hash module configured to performs a hash function on the scrambled data to generate a hash value. A second hash module, responsive to a collision occurring in the first hash module, perform a hash function on the scrambled data received from the first hash module. The use of a scrambler reduces collisions in the hash module outputs over time and multiple scramblers may be used to further reduce collisions.

Abstract: A battery packaging film includes a metal layer, a first bonding enhancement layer, a first bonding layer, a second bonding layer, a first protective layer, and a second protective layer. The first bonding enhancement layer is located on a first surface of the metal layer. The first bonding layer is located on a surface of the first bonding enhancement layer away from the metal layer. Because the first bonding enhancement layer is added to an upper surface of the metal layer, roughness of the upper surface of the metal layer is increased to enhance strength of bonding between the first protective layer and the metal layer and minimize occurrence of unintended separation of the first protective layer from the metal layer, thereby enhancing safety of the battery packaging.
