Problems solved by technology

No matter whether the two base stations establish the Xn interface or not, in the existing implementation scheme, the two base stations cannot determine the priority of the network slice supported by the other party
In the case where the two base stations have not established the Xn interface, the two base stations cannot determine the network slice supported by the other in the existing implementation scheme

example 1

[0206] Example 1, a TAI or TAC may correspond to the information of the supported network slices (the information of the network slices here includes the identifier of the network slice and the numerical value of the priority of the network slice):

[0207] >>>TAI or TAC

[0208] >>>S-NSSAI 1priority 1

[0209] S-NSSAI 2priority 2

[0210] S-NSSAI 3priority 3

[0211] In this example, each network slice corresponds to a priority value, which indicates the order of the network slice among the three network slices. The smaller the priority value of the network slice, the higher the priority of the network slice. higher. Or conversely, the higher the priority value of the network slice, the higher the priority of the network slice.

example 2

[0212] Example 2, a TAI or TAC may correspond to the information of the supported network slices (the information of the network slices here includes the identification of the network slices and the ordering of the network slices by priority):

[0213] >>>TAI or TAC

[0214] >>>S-NSSAI 1

[0215] S-NSSAI 2

[0216] S-NSSAI 3

[0217] For example, it can be indicated by a network slice list, and the network slices in the list from top to bottom or from front to back represent the priority of network slices from high to low. Or conversely, the network slices in the list from top to bottom or from front to back represent the priority of network slices from low to high.

[0218] 4. The S-NSSAI involved in any embodiment of the present application includes at least slice type / service type (slice / service type, SST) information, and may optionally also include slice differentiater (SD) information. SST information is used to indicate the behavior of network slices, such as networ...

example 1

[0245] Example 1: When all cells included in the second base station belong to TA1, and the received first message includes the identifier of the second base station, or the received first message includes the identifier of the second base station and TA1, See Table 1 for the content that can be included in the second message sent by the core network device. The network slices supported by TA1 include network slice #21, network slice #22, network slice #23, and network slice #24. Optionally, the second message further includes priorities corresponding to each supported network slice, as shown in Table 1. The first level here is a higher priority than the second level, and so on. Optionally, the second message may further include the identifier of TA1. In this way, the first base station can determine, through the second message, information on network slices supported by TA1 to which all cells included in the second base station belong.

Abstract

Embodiments of the present application disclose a communication method and related devices, wherein the method includes: a first base station sends a first message to a core network device, where the first message is used to request acquisition of a network slice supported by at least one cell included in the second base station or, the first message is used to request to obtain the information of the network slice supported by at least one tracking area to which at least one cell included in the second base station belongs, and the information of the network slice includes the identifier of the network slice and the priority of the network slice; The first base station receives a second message sent by the core network device, where the second message includes information about network slices supported by at least one tracking area to which at least one cell included in the second base station belongs. The present application helps to optimize the handover performance between the first base station and the second base station.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a communication method and related equipment. Background technique [0002] The fifth generation (5th Generation, 5G) communication system introduces the concept of network slicing, and the network slicing technology can realize the division of a physical network into multiple virtual networks. A virtual network is regarded as a "network slice", and each network slice is independent of each other. Different packet data unit (PDU) sessions in an end device may require network slices corresponding to each PDU session to provide services. In practical applications, the network slice supported by the base station and the priority of the network slice will affect the PDU session that can be established in the base station. Regardless of whether the two base stations establish the Xn interface, in the existing implementation solution, the two base stations can...
