Description

Activate method, terminal, base station and the communication system of different system SeNB

Technical field

The present invention relates to wireless communication technology field, more particularly to a kind of method of the different system SeNB of activation, terminal, base station And communication system.

Background technology

5G has the characteristics that higher rate and higher capacity as Next Generation Wireless Technology.In view of the deployment of 5G Frequency is relatively high, and at the initial stage of deployment, operator can generally consider to be disposed in hot spot region, realize that the capacity of system carries It rises.In order to reduce switching and the effective resource for utilizing two systems between 4G/5G, 4G/ is directed in current 3GPP Rel-14 Close intercommunication (Tight inter-working) problem of 5G carries out technical research, and main Research Thinking is to be based on doubly-linked The scheme for meeting (Dual Connectivity, DC) goes to solve the problems, such as intercommunication (Inter-working) between 4G/5G.

Dual link is the critical function that 3GPP Rel-12 are introduced, and is mainly used for solving based on the macro of non-ideal passback Radio resource aggregation problem between micro-base station, to effectively realize the promotion of user throughput and maximize system resource profit With rate.Its network architecture diagram is as shown in Figure 1.Wherein control plane is located at MeNB (Master eNB, master base station), is referred to as macro Base station.Can also support multiple carrier waves according to agreement macro base station, these carrier combinations be known as MCG (MeNB Cell Group, MeNB set of cells).And user plane is existed simultaneously in MeNB and SeNB (Slave eNB, slave base stations), wherein SeNB can also Referred to as small base station.As macro base station, SeNB also supports multiple carrier waves, these carrier combinations are known as SCG (SeNB Cell Group, SeNB set of cells).The main plot of its medium and small base station is referred to as PSCell (Primary Scell).

In 3GPP Current specifications, the flow of activation SeNB is as shown in Figure 2 in dual link operation.MeNB asks SeNB to carry out The addition of carrying, and negotiate UE ability (steps 201) with SeNB.SeNB leads to the access information of generation and carrying configuration information It crosses X2 interface and passes through MeNB (steps 202), MeNB is handed down to terminal (step 203) by RRC information.Terminal disappears according to instruction Breath completes the configuration (step 204~step 212) in access and the carrying of SeNB.Since the design original intention of agreement is to drop The low influence for core net, therefore, terminal are not related to any bearer update to core-network side when SeNB is accessed, only by macro Base station indicates that core net carries out relevant path switching.There are 5 kinds of basic framves in the current 4G/5G group-network constructions of 3GPP discuss Structure, one of them, as shown in Figure 3.New interface (this similar to X2 is introduced in the framework between the base stations 4G and the base stations 5G Patent is named as eX2 interfaces).The base stations 4G and 5G are connected respectively in respective core net, and are existed between the core net of 4G/5G The interface of intercommunication.

Based on above-mentioned framework, if 4G/5G dual link schemes continue to be multiplexed current dual link scheme, exist as follows Problem：

(1) it can not establish and carry in 5G：Current dual link scheme acquiescence control plane only there are one, and be maintained in MeNB Side.The addition operation of dual link will not relate to the foundation or reconstruction that are carried on core-network side.But 4G/5G intercommunication scenes In, the carrying of 5G can not be initiated to establish by the core net of 4G.

(2) base stations 4G and the base stations 5G can not understand the QoS systems of other side：4G nets are taken into consideration only in current dual link scheme Carrying change in network, there is no need to consider the problems of that QoS maps.It is contemplated that introducing network slice and QoS in 5G System may also can change, therefore the base stations 4G and the base stations 5G are required for understanding other side when executing the triage operator of carrying QoS systems and meaning of parameters, this will cause protocol stack design more complicated, and more parameters are needed to configure or interacted.

(3) scheme does not support the update across S-GW (Serving Gateway service webmaster)：In a 4 g system, business is cut The anchor point changed is S-GW, even if being also to think that after carrying is diverted to small base station S-GW will not be replaced in dual link operation.And 4G and 5G may have different S-GW (may be user plane management entity for 5G) in current architecture, therefore can not be multiplexed Bearer update step in current dual link scheme.

Introduction based on above-mentioned analysis and background, in the close intercommunication scenes of 4G/5G, current LTE dual links scheme needs Certain enhancing is carried out, to adapt to the needs of 4G/5G dual link scenes.
