Abstract
A communications method, apparatus, and system for controlling admission of terminal behavior by a network side, where the method includes: A mobility management network element receives a first session request message from a terminal. The first session request message carries user route selection policy (URSP) identification information. Then, the mobility management network element obtains URSP policy information based on the URSP identification information, and the mobility management network element sends a second session request message to a session management network element. The second session request message carries the URSP policy information, and the URSP policy information is used to formulate a policy rule for the terminal.
Claims20
A communications method, comprising:
- receiving, by a mobility management network element, a first session request message from a terminal, wherein the first session request message carries user equipment (UE) route selection policy (URSP) identification information;
- obtaining, by the mobility management network element, URSP policy information based on the URSP identification information;
- and
- sending, by the mobility management network element, a second session request message to a session management network element,
- wherein the second session request message carries the URSP policy information, and
- wherein the URSP policy information is for formulating a policy rule for the terminal.
A communications apparatus, comprising:
- a processor configured to obtain user equipment (UE) route selection policy (URSP) policy information based on URSP identification information;
- and
- a transceiver coupled to the processor and configured to:
- receive a first session request message from a terminal, wherein the first session request message carries the URSP identification information;
- and
- send a second session request message to a session management network element,
- wherein the second session request message carries the URSP policy information, and
- wherein the URSP policy information is for formulating a policy rule for the terminal.
The communications apparatus according to 11, wherein the processor is further configured to control, based on the URSP identification information, the transceiver to obtain the URSP policy information from a first policy control entity.
A communications apparatus, comprising:
- a processor configured to obtain user equipment (UE) route selection policy (URSP) policy information based on URSP identification information;
- and
- a transceiver coupled to the processor and configured to:
- receive a policy control request message from a session management network element, wherein the policy control request message carries the URSP identification information;
- and
- send a policy control response message to the session management network element,
- wherein the policy control response message carries the policy rule.
The communications apparatus according to 16, wherein the URSP identification information is a URSP rule identifier, and wherein the URSP policy information comprises:
- traffic descriptor information corresponding to a URSP rule identified by the URSP rule identifier, and one or more pieces of route selection descriptor (RSD) information.
