Abstract: This application provides a parameter determining method and a communications entity. The method includes: When a UE is in a system in which an evolved packet system (EPS) network and a 5GS network interwork, the UE is currently located in the 5GS network, and QoS parameters used include an authorized UE aggregate maximum bit rate (AMBR) and an authorized session AMBR of a session. Because of movement of the UE, the UE needs to be handed over to the EPS network, and QoS parameters that need to be used for the UE in the EPS network include an authorized UE AMBR and an authorized access point name (APN) AMBR. The authorized APN AMBR is determined by a first communications entity based on at least one of a subscribed APN AMBR or the authorized session AMBR of the PDU session, and the authorized UE AMBR is determined by a second communications entity based on the authorized APN AMBR.

Abstract: The present invention discloses a service processing method and apparatus, and relates to the communications field. The method includes: receiving trigger information sent by an intermediary device; and assisting, based on the trigger information, the intermediary device in negotiating with UE and a network server, to enable the intermediary device to obtain a first key, where the first key is used by the intermediary device to decrypt ciphertexts sent by the UE and the network server, the ciphertext is obtained after the UE or the network server encrypts service information by using a second key, and the first key is corresponding to the second key. The present invention resolves a problem that an intermediary device cannot provide service optimization for user equipment and a network server because the intermediary device cannot decrypt ciphertext, and achieves an effect of expanding a usage scope of service optimization.

Abstract: Embodiments provide a location area management method, a control node, and user equipment (UE). The method is applied to a communications system including a control plane node, and the control plane node stores an upper-level area identity list of UE. The control plane node determines a lower-level area identity list of the UE based on the upper-level area identity list. The control plane node sends the lower-level area identity list to the UE. When the upper-level area identity list is allocated to the UE, the lower-level area identity list is allocated to the UE. The lower-level area identity list includes fewer areas than the upper-level area identity list, so that when the control plane node pages the UE, paging is performed in an area corresponding to the lower-level area identity list, thereby reducing signaling overheads of a network side device.

Abstract: The present application discloses a congestion processing method. The method includes: sending, by the source host, a resource data packet on each stream based on a transmit rate of each stream, where when the router determines that the transmission link is congested, the router sets a congestion flag in the resource data packet; receiving, from each stream, a response data packet forwarded by the router, where at least one response data packet on at least one stream includes a congestion notification flag; and performing congestion processing based on the congestion notification flag and the transmission priority of each stream.

Abstract: Embodiments of the present invention provide an address management apparatus, system, and method for communication over the Multipath Transmission Control Protocol (MTCP). A processing module allocates a corresponding internet protocol (IP) address to each MPTCP session, where the MPTCP session is an MPTCP session between a first host and a second host, the first host is the host supporting MPTCP, and the second host is the host not supporting MPTCP, and when the MPTCP session is terminated, the processing module releases the corresponding IP address allocated to the MPTCP session. A transceiver module sets up the MPTCP session according to the IP address.
