2. The method of claim 1, wherein the matching each URSP rule with the service to be run comprises:
determining the service identification information of the service to be operated;
and matching the identification information in each URSP rule with the service identification information of the service to be operated.
3. The method of claim 1, further comprising:
and if the target URSP rule is judged to be the URSP rule with the lowest priority in the URSP rules, ending the matching process with the service to be operated.
4. A network slice matching apparatus, comprising:
the device comprises a determining unit, a judging unit and a judging unit, wherein the determining unit is used for determining the priority of each pre-acquired UE routing strategy URSP rule when receiving a service to be operated; wherein, each URSP rule comprises a limited access identification;
the matching unit is used for matching each URSP rule with the service to be operated in sequence according to the sequence of the priorities of the URSP rules from high to low;
the first judgment unit is used for determining the URSP rule which is matched with the business to be transported currently as a target URSP rule, and judging whether the network slice in the target URSP rule is an available slice or not if the target URSP rule is matched with the business to be transported;
a bearing unit, configured to bear the service to be run by using the network slice in the target URSP rule if the network slice in the target URSP rule is an available slice, and end a matching process with the service to be run;
a second determining unit, configured to determine whether the limited access identifier included in the target URSP rule is the first identifier if the network slice in the target URSP rule is an unavailable slice; the first identification is used for representing that the service to be run is appointed to be carried by a network slice in the target URSP rule;
a first end unit, configured to end a matching process with the service to be run if the limited access identifier included in the target URSP rule is a first identifier, and refuse to carry the service to be run;
a third determining unit, configured to determine, if the limited access identifier included in the target URSP rule is not the first identifier, whether the target URSP rule is the URSP rule with the lowest priority in each of the URSP rules, and if the target URSP rule is not the URSP rule with the lowest priority in each of the URSP rules, continue the matching process with the service to be operated until a network slice in which the URSP rule exists is an available slice, or a network slice in the URSP rule exists is an unavailable slice and the limited access identifier included in the URSP rule is the first identifier, end the matching process with the service to be operated.
5. The apparatus of claim 4, wherein the matching unit comprises:
a determining subunit, configured to determine service identification information of the service to be operated;
and the matching subunit is used for matching the identification information in each URSP rule with the service identification information of the service to be operated.
6. The apparatus of claim 4, further comprising:
and a second ending unit, configured to end the matching process with the service to be run if it is determined that the target URSP rule is the URSP rule with the lowest priority in the URSP rules.
