Abstract

A route configuration method includes determining, by a session management network element, that a first terminal in a first group is allowed to communicate with a second terminal in a second group. The route configuration method further includes sending, by the session management network element, first forwarding information to a first user plane network element. The first user plane network element is configured to provide a service for the first terminal. The first forwarding information is useable by the first user plane network element to forward a first packet. The first packet is to be sent by the first terminal to the second terminal.

Dependent claims

A communication method, wherein the method comprises:

determining a first uplink carrier in response to a first condition being met, wherein the first condition comprises at least one of the following:
channel quality of a third downlink carrier being less than or equal to a threshold K1, and the third downlink carrier is useable for downlink communication before the first uplink carrier is determined;
channel quality of a downlink signal on the first uplink carrier is greater than or equal to a threshold K2;
or
channel quality of the second downlink carrier is greater than or equal to a threshold K3, and the second downlink carrier is configured to be bound to the first uplink carrier to perform the uplink transmission and the downlink transmission and is currently useable for downlink measurement;
and
determining at least one of a first cell or a first downlink carrier based on the first uplink carrier;
wherein the first uplink carrier is useable for uplink communication, and the first downlink carrier is useable for downlink communication;
and
wherein the determining the first cell comprises:
determining that the first uplink carrier is the first cell;
determining that the first uplink carrier and at least one uplink carrier are a cell;
determining that the first uplink carrier and the first downlink carrier are the cell;
or
determining that the first uplink carrier, at least one uplink carrier, and the first downlink carrier are the cell;
and
the determining the first downlink carrier comprises:
determining that the first uplink carrier and the first downlink carrier are associated carriers;
determining that the first uplink carrier, the at least one uplink carrier, and the first downlink carrier are associated carriers;
determining that the first cell and a second cell are associated cells, wherein the second cell comprises the first downlink carrier;
or
determining that the first uplink carrier, the at least one uplink carrier, and the first downlink carrier are associated carriers, and determining that a second downlink carrier is useable for downlink measurement, wherein the second downlink carrier is configured to be bound to the first uplink carrier to perform uplink transmission and downlink transmission.

wherein the one or more processors being configured to execute the non-transitory instructions to thereby cause the apparatus to determine the first cell comprises further causing the apparatus to:
determine that the first uplink carrier is the first cell;
determine that the first uplink carrier and at least one uplink carrier are a cell;
determine that the first uplink carrier and the first downlink carrier are the cell;
or
determine that the first uplink carrier, at least one uplink carrier, and the first downlink carrier are the cell;
and
the one or more processors being configured to execute the non-transitory instructions to thereby cause the apparatus to determine the first downlink carrier comprises further causing the apparatus to:
determine that the first uplink carrier and the first downlink carrier are associated carriers;
determine that the first uplink carrier, the at least one uplink carrier, and the first downlink carrier are associated carriers;
determine that the first cell and a second cell are associated cells, wherein the second cell comprises the first downlink carrier;
or
determine that the first uplink carrier, the at least one uplink carrier, and the first downlink carrier are associated carriers, and determine that a second downlink carrier is useable for downlink measurement, wherein the second downlink carrier is configured to be bound to the first uplink carrier to perform uplink transmission and downlink transmission.
