Communication method, access network equipment and ue in a heterogeneous network

Abstract

A communication method, an access network device, and a UE in a heterogeneous network, the method comprising: a source access network device generates a temporary priority list, wherein the temporary priority list includes a frequency point of a source network, a frequency point of a target network point, the priority of the frequency point of the source network, and the priority of the frequency point of the target network, and the source access network device is the device that connects the UE to the source network; the source access network device sends the temporary priority list to A target access network device, where the target access network device is a device that connects the UE to the target network; the source access network device sends a temporary priority list to the UE. The invention can ensure the consistency of broadcast messages among networks of different standards, and avoid causing UE ping-pong reselection.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication method, access network equipment and UE in a heterogeneous network. Background technique [0002] In the global system for mobile communications (GSM) and Long Term Evolution (LTE) networking, or LTE and Universal Mobile Telecommunications System (Universal MobileTelecommunications System, UMTS) networking, or GSM, LTE and UMTS In the networking scenario, when the service load on the access network side of a certain system is high, a load transfer algorithm is generally activated to adjust the service strategy and transfer the User Equipment (UE) to other systems of the co-coverage network. Among them, the UE in the connected (Connected) state is the currently measurable load, and the UE in the idle (IDLE) state is the potential load. The UE in the IDLE state may initiate a service with a large amount of data in the near future. According to the type of UE trans...

Problems solved by technology

[0004] The main problem in the IDLE state load transfer process in the prior art is that the reselection priorities between networks of different standards cannot be coordinated

Generally, the priority of frequency reselection in each standard network is the same during the initial network configuration. When a single standard network unilaterally adjusts the priority, the content of the broadcast message between the standard networks is not coordinated, and the load transfer effect is poor.

For example, when the LTE load is too high, the LTE broadcast UMTS frequency has a high priority, and the UE reselects to UMTS. After the UE reselects to UMTS, the content of the UMTS network system broadcast message may be that the UMTS frequency has a low priority, and the UE is relatively easy. Reselection back to LTE, causing ping-pong reselection
