Abstract: A method, a device and a system for session routing are provided. The method includes: when a first terminal enters a first network in which a first routing device is located, the first routing device obtains an address of a second routing device in a second network; the first routing device establishes a tunnel with the second routing device according to the address of the second routing device; and the first routing device maintains a session between the first terminal and the second routing device through the tunnel. There is no need to set a home network for the terminal, and since the routing device to which the terminal belongs varies with the network in which the terminal is located, the communication traffic of the terminal may not be concentrated on one routing device for forwarding, thus reducing the processing load of a single routing device.

Abstract: Embodiments of the present invention provide a routing method and a routing apparatus. The routing method includes: receiving a first data packet sent by a first mobile node to a first communication peer end, where the first mobility router is a mobility router in a visited network of the first mobile node, and the first data packet includes an address of the first communication peer end; acquiring an address of a proxy routing entity based on the address of the first communication peer end, where the proxy routing entity is located in a communication path between the first mobility router and the first communication peer end; establishing a first tunnel to the proxy routing entity based on the address of the proxy routing entity; and transmitting, by using the first tunnel, a data packet sent by the first communication peer end to the first mobile node.

Abstract: This application provides a spectrum resource determining method and apparatus, and relates to the field of communication technologies. In the method, sharing information indicating that N first cells and one second cell share a first frequency band may be obtained, and a spectrum resource of each first cell among the N first cells in the first frequency band and a spectrum resource of the second cell in the first frequency band may be determined, where a coverage area of each first cell among the N first cells overlaps a coverage area of the second cell. The first cells can be LTE cells, and the second cell can be an NR cell.

Abstract: A channel estimation method, a related device, and a system are described. A method for channel estimation may include determining when there is a damaged cell measurement reference signal (CRS) in a plurality of CRSs in target resource blocks (RBs), where the target RBs are RBs in compressed standard bandwidth. The method may also include performing, by a terminal, channel estimation by using an undamaged CRS instead of the damaged CRS in the plurality of CRSs. Based on the method, accuracy of channel estimation can be improved, and a problem of a relatively large error of a demodulation result of a data demodulation service performed based on the channel estimation result is resolved.
