101. And receiving at least one first rule identification sent by the network equipment.

Wherein the at least one first rule identifier is configured to uniquely identify a set of first rule parameters within a given Public Land Mobile Network (PLMN), e.g., one or more PLMNs.

102. According to the at least one first rule identifier, obtaining a pre-configured first rule parameter corresponding to each first rule identifier in the at least one first rule identifier; each first rule parameter comprises at least one of a wireless local area network selection rule parameter and a terminal routing rule parameter.

After obtaining the first rule parameters, the terminal may perform rule matching processing on the first rule parameters at corresponding time, and select a network connection and/or establish a Protocol Data Unit (PDU) session using the matched first rule parameters.

The execution main bodies of 101 to 103 may be terminals.

The main idea of this embodiment is that a network device issues a rule identifier, that is, a first rule identifier, to a terminal, so that the terminal can flexibly use a rule parameter, that is, a first rule parameter, pre-configured in the terminal according to the rule identifier, and a rule parameter that is fixedly used does not need to be pre-configured in the terminal, thereby improving the configuration flexibility of a terminal policy.

Thus, by receiving at least one first rule identifier sent by the network device, and further according to the at least one first rule identifier, obtaining a preconfigured first rule parameter corresponding to each first rule identifier in the at least one first rule identifier; each first rule parameter comprises at least one of a wireless local area network selection rule parameter and a terminal routing selection rule parameter, and a rule identifier, namely a first rule identifier, is issued to the terminal through the network equipment, so that the terminal can flexibly adopt the rule parameter, namely the first rule parameter, which is pre-configured in the terminal according to the rule identifier, and the rule parameter which is fixedly adopted does not need to be pre-configured in the terminal, thereby improving the configuration flexibility of the terminal strategy.

Optionally, in a possible implementation manner of this embodiment, in 101, at least one first rule identifier sent by the network device through a high layer signaling, a system broadcast, or Downlink Control Information (DCI) may be specifically received.

Specifically, the terminal may specifically receive at least one first rule identifier sent by the network device through higher layer signaling, system broadcast, or DCI.

For example, the higher layer signaling may be a Radio Resource Control (RRC) message, and specifically, the at least one first rule identifier may be carried by an Information Element (IE) in the RRC message, and the RRC message may be an RRC message in the prior art, for example, an RRC CONNECTION RECONFIGURATION (RRC CONNECTION RECONFIGURATION) message and the like.

For another example, the high-level signaling may be a Media Access Control (MAC) Control Element (CE) message, and specifically, the at least one first rule identifier may be carried by adding a new MAC CE message.

For another example, the at least one first rule identifier may be carried by a spare bit (bit) in an existing Master Information Block (MIB) or a System Information Block (SIB) in the System broadcast message, or a new SIB may be added to carry the at least one first rule identifier.

Optionally, in a possible implementation manner of this embodiment, each of the first rule parameters may include, but is not limited to, at least one of a Wireless Local Area Network Selection Policy (WLANSP) parameter and a terminal routing Selection Policy (URSP) parameter, which is not particularly limited in this embodiment.

Specifically, the WLANSP parameters may include, but are not limited to, at least one of the following parameters:

a Validity condition (Validity Conditions) of the resident mobile communication network;

a preferred access point name list (preferred SSID) of the wlan, e.g., a Service Set Identifier (SSID) in a Wireless Fidelity (Wi-Fi) network;

minimum backhaul threshold (minimum backhaul threshold);

preferred roaming buddy list (PreferredRoamingPartnerList); and

maximum service support system (BSS) load (MaximumBSSLoad).

Specifically, the URSP parameters may include, but are not limited to, at least one of the following parameters:

a Traffic filter (Traffic filter);

direct offload (Direct offload);

network Slice information (Slice Info);

service Continuity patterns (Continuity Types);

data Network Name (DNNs); and

access network Type (Access Type).

Optionally, in a possible implementation manner of this embodiment, each of the first rule parameters may further include a first Priority parameter (Priority) for indicating a Priority of use of the first rule parameter. Then the use of said each first rule parameter is decided by said first priority parameter.

In a specific implementation process, if the terminal is matched to multiple first rule parameters, the terminal may preferentially use the first rule parameter with the highest priority indicated by the first priority parameter according to the first priority parameter included in each first rule parameter.

In another specific implementation process, in the case that there is more than one highest first priority parameter, the usage priority of the first rule parameter may be specifically indicated by the first rule identifier. Then, if the first priority parameters are the same, the usage of each first rule parameter may be determined by the first rule identifier corresponding to the first rule parameter.

For example, under the condition that there is more than one highest first priority parameter, the terminal may preferentially use the first rule parameter whose first rule identifier satisfies a preset priority rule, such as a maximum value or a minimum value, according to the first rule identifier corresponding to each first rule parameter.

Optionally, in a possible implementation manner of this embodiment, the second rule parameter corresponding to at least one second rule identifier and each second rule identifier in the at least one second rule identifier, which are sent by the network device, may also be further received.

Wherein the at least one second rule identifier is configured to uniquely identify a set of second rule parameters for different terminals. The second rule identification may be reused within the same PLMN but needs to be unique for the terminal.

After obtaining the second rule parameters, the terminal may perform rule matching processing on the second rule parameters at corresponding time, and select a network connection and/or establish a Protocol Data Unit (PDU) session using the matched second rule parameters.

It should be noted that, in this embodiment, "receiving at least one first rule identifier sent by a network device" and "receiving at least one second rule identifier sent by the network device and second rule parameters corresponding to each of the at least one second rule identifier" do not have a fixed execution sequence, and may first execute "receiving at least one first rule identifier sent by the network device", then execute "receiving at least one second rule identifier sent by the network device and second rule parameters corresponding to each of the at least one second rule identifier", or may also first execute "receiving at least one second rule identifier sent by the network device and second rule parameters corresponding to each of the at least one second rule identifier", then execute "receiving at least one first rule identifier sent by the network device", or "receiving at least one first rule identifier sent by the network device" may be performed simultaneously with "receiving at least one second rule identifier sent by the network device and the second rule parameter corresponding to each second rule identifier in the at least one second rule identifier", which is not particularly limited in this embodiment.

Specifically, the network device may determine which first rule identifier and which second rule identifier and the corresponding second rule parameter are sent according to the congestion condition of the current network and the limitation of sending the cell length, which is not particularly limited in this embodiment.

Optionally, in a possible implementation manner of this embodiment, the at least one second rule identifier and the second rule parameter corresponding to each of the at least one second rule identifier may be specifically received, where the second rule parameter is sent by the network device through a high-layer signaling, a system broadcast, or Downlink Control Information (DCI).

Specifically, the terminal may specifically receive the at least one second rule identifier sent by the network device through the higher layer signaling, the system broadcast, or the DCI, and the second rule parameter corresponding to each second rule identifier in the at least one second rule identifier.

For example, the higher layer signaling may be a Radio Resource Control (RRC) message, specifically, the at least one second rule identifier and the second rule parameter corresponding to each second rule identifier may be carried by an Information Element (IE) in the RRC message, and the RRC message may be an RRC message in the prior art, for example, an RRC CONNECTION RECONFIGURATION (RRC CONNECTION RECONFIGURATION) message and the like, which is not limited in this embodiment, and the at least one second rule identifier and the second rule parameter corresponding to each second rule identifier are carried by extending an IE of an existing RRC message, or the RRC message may also be different from an existing RRC message in the prior art.

For another example, the high-level signaling may be a Media Access Control (MAC) Control Element (CE) message, and specifically, a new MAC CE message may be added to carry the at least one second rule identifier and the second rule parameter corresponding to each second rule identifier.

For another example, the at least one second rule identifier and the second rule parameter corresponding to each second rule identifier may be carried by a spare bit (bit) in an existing Master Information Block (MIB) or a System Information Block (SIB) in the System broadcast message, or a new SIB may be added to carry the at least one second rule identifier and the second rule parameter corresponding to each second rule identifier.

Optionally, in a possible implementation manner of this embodiment, each second rule parameter may include, but is not limited to, at least one of a Wireless Local Area Network Selection Policy (WLANSP) parameter and a terminal routing Selection Policy (URSP) parameter, which is not particularly limited in this embodiment.

minimum backhaul threshold (minimum backhaul threshold);

preferred roaming buddy list (PreferredRoamingPartnerList); and

maximum service support system (BSS) load (MaximumBSSLoad).

a Traffic filter (Traffic filter);

direct offload (Direct offload);

network Slice information (Slice Info);

service Continuity patterns (Continuity Types);

data Network Name (DNNs); and

access Type (Access Type).

Optionally, in a possible implementation manner of this embodiment, each of the second rule parameters may further include a second Priority parameter (Priority) to indicate a Priority of use of the second rule parameter. Then the use of said each second rule parameter is decided by said second priority parameter.

In a specific implementation process, if the terminal is matched to a plurality of second rule parameters, the terminal may preferentially use the second rule parameter with the highest priority indicated by the second priority parameter according to the second priority parameter included in each second rule parameter.

In another specific implementation process, in the case that there is more than one highest second priority parameter, the usage priority of the second rule parameter may be specifically indicated by the second rule identifier. Then, if the second priority parameters are the same, the usage of each second rule parameter may be determined by the second rule identifier corresponding to the second rule parameter.

For example, under the condition that there is more than one highest second priority parameter, the terminal may preferentially use the second rule parameter that satisfies the preset priority rule, such as the maximum value or the minimum value, according to the second rule identifier corresponding to each second rule parameter.

Optionally, in a possible implementation manner of this embodiment, the priority of use of the first rule parameter is greater than the priority of use of the second rule parameter.

Specifically, if the terminal matches two types of parameters, namely, the first rule parameter and the second rule parameter, since the priority of use of the first rule parameter is greater than that of use of the second rule parameter, the terminal may preferentially use the first rule parameter.

Optionally, in a possible implementation manner of this embodiment, if the at least one first rule identifier is not received, and the at least one second rule identifier and the second rule parameter corresponding to each second rule identifier in the at least one second rule identifier are not received, at least one third rule parameter configured in advance may be obtained.

After obtaining the third rule parameters, the terminal may perform rule matching processing on the third rule parameters at corresponding time, and select a network connection and/or establish a Protocol Data Unit (PDU) session using the matched third rule parameters.

Optionally, in a possible implementation manner of this embodiment, each of the third rule parameters may include, but is not limited to, at least one of a Wireless Local Area Network Selection Policy (WLANSP) parameter and a terminal routing Selection Policy (URSP) parameter, which is not particularly limited in this embodiment.

minimum backhaul threshold (minimum backhaul threshold);

preferred roaming buddy list (PreferredRoamingPartnerList); and

maximum service support system (BSS) load (MaximumBSSLoad).

a Traffic filter (Traffic filter);

direct offload (Direct offload);

network Slice information (Slice Info);

service Continuity patterns (Continuity Types);

data Network Name (DNNs); and

access network Type (Access Type).

Optionally, in a possible implementation manner of this embodiment, each of the third rule parameters may further include a third Priority parameter (Priority) to indicate a Priority of use of the third rule parameter. Then the use of said each third rule parameter is decided by said third priority parameter.

In a specific implementation process, if the terminal is matched to a plurality of third rule parameters, the terminal may preferentially use the third rule parameter with the highest priority indicated by the third priority parameter according to the third priority parameter included in each third rule parameter.

In another specific implementation process, in the case that there is more than one highest third priority parameter, the usage priority of the third rule parameter may be specifically indicated by the third rule identifier. Then, if the third priority parameters are the same, the usage of each third rule parameter may be determined by the third rule identifier corresponding to the third rule parameter.

For example, under the condition that there is more than one highest third priority parameter, the terminal may preferentially use the third rule parameter that satisfies the preset priority rule, such as the maximum value or the minimum value, according to the third rule identifier corresponding to each third rule parameter.

Optionally, in a possible implementation manner of this embodiment, the priority of use of the second rule parameter is greater than the priority of use of the third rule parameter.

Specifically, if the terminal matches two types of parameters, namely, the second rule parameter and the third rule parameter, since the priority of use of the second rule parameter is greater than the priority of use of the third rule parameter, the terminal may preferentially use the second rule parameter.

If the terminal matches two types of parameters, namely the first rule parameter and the third rule parameter, the terminal can preferentially use the first rule parameter because the use priority of the first rule parameter is greater than the use priority of the second rule parameter and the use priority of the second rule parameter is greater than the use priority of the third rule parameter.

If the terminal matches two types of parameters, namely the first rule parameter, the second rule parameter and the third rule parameter, the terminal can preferentially use the first rule parameter because the use priority of the first rule parameter is greater than the use priority of the second rule parameter and the use priority of the second rule parameter is greater than the use priority of the third rule parameter.

In this embodiment, according to the configuration mode of the terminal policy, the first rule parameter may be referred to as a static rule parameter, the second rule parameter may be referred to as a dynamic rule parameter, and the third rule parameter may be referred to as a default rule parameter.

In this embodiment, by receiving at least one first rule identifier sent by a network device, a preconfigured first rule parameter corresponding to each first rule identifier in the at least one first rule identifier is obtained according to the at least one first rule identifier; each first rule parameter comprises at least one of a wireless local area network selection rule parameter and a terminal routing selection rule parameter, and a rule identifier, namely a first rule identifier, is issued to the terminal through the network equipment, so that the terminal can flexibly adopt the rule parameter, namely the first rule parameter, which is pre-configured in the terminal according to the rule identifier, and the rule parameter which is fixedly adopted does not need to be pre-configured in the terminal, thereby improving the configuration flexibility of the terminal strategy.

Fig. 2 is a schematic flowchart of another terminal policy configuration method according to another embodiment of the present invention, as shown in fig. 2.

201. Sending at least one first rule identifier to a terminal, so that the terminal can obtain a preconfigured first rule parameter corresponding to each first rule identifier in the at least one first rule identifier according to the at least one first rule identifier; each first rule parameter comprises at least one of a wireless local area network selection rule parameter and a terminal routing rule parameter.

After the terminal obtains the first rule parameters, the terminal may perform rule matching processing on the first rule parameters at corresponding time, and select a network connection and/or establish a Protocol Data Unit (PDU) session by using the matched first rule parameters.

It should be noted that the execution subject of 201 may be a network device.

In this way, at least one first rule identifier is sent to a terminal, so that the terminal can obtain a first rule parameter which is configured in advance and corresponds to each first rule identifier in the at least one first rule identifier according to the at least one first rule identifier; each first rule parameter comprises at least one of a wireless local area network selection rule parameter and a terminal routing selection rule parameter, and a rule identifier, namely a first rule identifier, is issued to the terminal through the network equipment, so that the terminal can flexibly adopt the rule parameter, namely the first rule parameter, which is pre-configured in the terminal according to the rule identifier, and the rule parameter which is fixedly adopted does not need to be pre-configured in the terminal, thereby improving the configuration flexibility of the terminal strategy.

Optionally, in a possible implementation manner of this embodiment, the at least one first rule identifier may be specifically sent to the terminal through a higher layer signaling, a system broadcast, or Downlink Control Information (DCI).

Specifically, the network device may specifically send the at least one first rule identifier to the terminal through higher layer signaling, system broadcast, or DCI.

After obtaining the second rule parameters, the terminal may perform rule matching processing on the second rule parameters at corresponding time, and use the matched second rule parameters to select a network connection and/or establish a PDU session.

It should be noted that, in this embodiment, the "sending at least one first rule identifier to the terminal" and the "sending at least one second rule identifier and the second rule parameter corresponding to each of the at least one second rule identifier to the terminal" are executed without a fixed execution sequence, and the "sending at least one first rule identifier to the terminal" may be executed first, the "sending at least one second rule identifier and the second rule parameter corresponding to each of the at least one second rule identifier to the terminal" may be executed then, or the "sending at least one second rule identifier and the second rule parameter corresponding to each of the at least one second rule identifier to the terminal" may be executed then, the "sending at least one first rule identifier to the terminal" may be executed then, or the "sending at least one first rule identifier to the terminal" may be executed simultaneously The terminal sends at least one second rule identifier and a second rule parameter corresponding to each second rule identifier in the at least one second rule identifier, which is not particularly limited in this embodiment.

In this implementation manner, the at least one second rule identifier and the second rule parameter corresponding to each second rule identifier in the at least one second rule identifier may be specifically sent to the terminal through a higher layer signaling, a system broadcast, or Downlink Control Information (DCI).
