Abstract
A communication method in an inter-RAT network, an access network device, and UE are provided. The method includes: generating, by a source access network device, a temporary priority list, where the temporary priority list includes a frequency of a source network, a frequency of a target network, a priority of the frequency of the source network, and a priority of the frequency of the target network; sending, by the source access network device, the temporary priority list to a target access network device; and sending, by the source access network device, the temporary priority list to the UE. The present application can ensure that broadcast messages in networks of different RATs are consistent and prevent ping-pong reselection of the UE.
Claims18
A communication method in an inter-radio network technology (inter-RAT) network comprising a source network of a first RAT and a target network of a second RAT, the method comprising:
- detecting, by a source access network device, a load of a serving cell, the serving cell being a cell of the source network and on which a user equipment (UE) currently camps, the source access network device being a device that enables the UE to access the source network;
- when the load of the serving cell is greater than a first load threshold, detecting, by the source access network device, a load of the source network;
- when the load of the source network is greater than a second load threshold, generating, by the source access network device, a temporary priority list comprising a frequency of the source network, a frequency of the target network, a priority of the frequency of the source network, and a priority of the frequency of the target network;
- sending, by the source access network device, the temporary priority list to a target access network device that enables the UE to access the target network;
- and
- sending, by the source access network device, the temporary priority list to the UE.
An access network device for enabling user equipment (UE) to access a source network, the access network device comprising:
- a non-transitory computer readable storage medium configured to store a program;
- and
- a processor configured to execute the program to:
- detect a load of a serving cell, the serving cell being a cell of the source network and on which the UE currently camps;
- when the load of the serving cell is greater than a first load threshold, detect a load of the source network;
- when the load of the source network is greater than a second load threshold, generate a temporary priority list comprising a frequency of the source network, a frequency of a target network, a priority of the frequency of the source network, and a priority of the frequency of the target network;
- send the temporary priority list to a target access network device, wherein the target access network device is a device that enables the UE to access the target network;
- and
- send the temporary priority list to the UE.
An access network device for enabling user equipment (UE) to access a target network, the access network device comprises:
- a non-transitory computer readable storage medium configured to store a program;
- and
- a processor configured to execute the program to:
- receive a temporary priority list sent by a source access network device, wherein the temporary priority list comprises a frequency of a source network, a frequency of the target network, a priority of the frequency of the source network, and a priority of the frequency of the target network, and wherein the source access network device is a device that enables the UE to access the source network, and
- send the temporary priority list to the UE in the target network, wherein the temporary priority list is the same as a temporary priority list sent by the source access network device directly to the UE in a source network, wherein the temporary priority list sent by the source access network device was received by the UE before the UE performed a network reselection from the source network to the target network according to the priorities of the frequencies in the temporary priority list.
A user equipment (UE), comprising:
- a non-transitory computer readable storage medium configured to store a program;
- and
- a processor configured to execute the program to:
- receive a temporary priority list sent by a source access network device, wherein the temporary priority list comprises a frequency of a source network, a frequency of a target network, a priority of the frequency of the source network, and a priority of the frequency of the target network, and the source access network device is a device that enables the UE to access the source network,
- perform network reselection according to the priorities of the frequencies in the temporary priority list, and
- receive, when the UE reselects the target network, the temporary priority list that a target access network device receives from the source access network device and sends to the UE, wherein the target access network device is a device that enables the UE to access the target network.
