Abstract: The present invention relates to the field of communications technologies and discloses a tunnel establishment method and apparatus. Even if an entity for executing the solution is not changed, a type of a tunnel established for each service of a terminal may be the same or may be different. For example, a first tunnel and a second tunnel may be established for a current service of the terminal, and a third tunnel may be established for a next service of the terminal. This eases congestion in a backbone network between a secondary access network node and a primary access network node. Alternatively, this avoids using a directly connected tunnel as a tunnel established between the secondary access network node and a core network user plane node when a core network control plane node needs to receive and send too much path switching signaling.

Abstract: This application provides example data packet transmission methods and example communications apparatuses. One example method includes receiving a data packet, where the data packet is in an undelivered state. The data packet can then be delivered during running of a reordering timer upon an arrival of a first delay cut-off moment corresponding to the data packet or an arrival of a second delay cut-off moment of an additional data packet before the data packet in a reordering window.

Abstract: Embodiments of the present invention relate to an RRC connection method and a serving node. In the embodiments, an RRC connection is established between an anchor node and UE. Therefore, when an serving node of the UE is switched, a connection between an MME and the anchor node does not change. When the MME needs to send a paging message, the MME does not need to send the paging message to all base stations in a TA area that corresponds to the paging message, thereby effectively reducing signaling load of a core network.

Abstract: An apparatus includes a processor, and a non-transitory computer-readable storage medium coupled to the processor, and configured to store programmable instructions. When executed by the processor the programmable instructions cause the apparatus to maintain a transmission status of a previous data packet of a first access stratum entity, and adjust a transmission parameter of a current data packet, in response to the transmission status of the previous data packet being a transmission failure.
