Description

Access control method, access method, device, base station, user equipment, and entity

The present invention relates to the field of mobile communication technologies, and in particular, to a carrier aggregation access control method, an access method, an apparatus, a base station, a user equipment, and a mobility management entity between base stations. BACKGROUND With the rapid development of mobile communication systems, future Long Term Evolution (LTE)/Long Term Evolution (LTE-A) systems need to provide higher speed and wider coverage services. Transmission can meet the higher demand for communication services. As spectrum resources become more and more scarce, in the prior art, in order to further improve the spectrum efficiency and system throughput of the system, a new carrier aggregation (CA) technology is proposed, which has been adopted as LTE-A. One of the important system enhancement technologies of the evolved version in the system.

At present, for the progress of carrier aggregation in the 3rd Generation Partnership Project (3GPP), the signaling and requirements defined by the carrier aggregation technology in the standard are mainly for the intra-e B scenario, that is, The primary cell and the secondary cell serving a certain user equipment (UE, User Equipment) share a "site (site)", which is mainly controlled by one base station.

However, the scenario of carrier aggregation is not limited to the case of intra-eNB. In the actual carrier aggregation application scenario, the primary cell and the secondary cell "do not share a common site" may occur. This is the carrier aggregation between the base stations. The inter-base-station carrier aggregation can be further divided into carrier aggregation between macro base stations and carrier aggregation between macro base stations and low power nodes (LPNs). In the current standard, there is less content involved in carrier aggregation between base stations. For the access control algorithm, since the primary cell adds and deletes the secondary cell, it needs to pass the X2 port or the S1 port to perform corresponding Signaling interaction, therefore, the flow of access control is completely different from that of intra-eNB.

Therefore, in the prior art, since the primary cell and the secondary cell do not share the common site, the primary cell knows less information about the resources of the secondary cell, and how to perform signaling interaction between the primary cell and the secondary cell to effectively ensure that the UE can further It is a technical problem to be solved to effectively access the network and improve the success rate of random access of the UE, thereby improving the throughput and user experience of the entire network.

In this embodiment, it is assumed that there is an X2 port connection between the source e B (Pcell) and the target eNB (Scell), and the user equipment supporting carrier aggregation communicates with the secondary cell (Pcell) through RRC signaling. In this embodiment, the user equipment UE is a user equipment that supports carrier aggregation, and the source service node is a service node to which the primary cell belongs, and the target service node is a service node to which the secondary cell belongs, and specifically includes: Step 901: The user equipment that supports the carrier aggregation sends the RRM-related measurement report to the source serving node to which the primary cell belongs (in this embodiment, the e Bl to which the primary cell Pcell belongs is taken as an example);

The RRM-related measurement report is the RRM of the user equipment at each frequency point and each node, and the content of the measurement report may include an RSRP measurement result, an RSRQ measurement result, or other measurement result. This embodiment takes the RSRP measurement result as an example. The reported form is as follows, but is not limited to this:

After receiving the secondary cell resource request message, the target serving node allocates a secondary cell frequency point allocated to the user equipment according to its own service and load condition, and a corresponding uplink random access physical resource block resource. The secondary cell resource request acknowledgement message sent by the target serving node to the source serving node includes: a secondary cell frequency point allocated by the target serving node to the user equipment, and a corresponding uplink random access physical resource block resource. And the source serving node sends the secondary cell frequency point allocated by the target serving node to the user equipment, and the corresponding uplink random access physical resource block resource is sent to the user equipment by using the RRC connection reconfiguration message, where the user equipment is based on the A secondary cell frequency point and an uplink PRB resource, a random access request is initiated on the secondary cell, and the wireless link establishment of the Scell is completed;

Step 1005: The source serving node selects one most suitable frequency point and a corresponding uplink random access physical resource block from the plurality of suitable frequency points according to the service in the cell and the load condition of each frequency point. That is, after the source serving node receives the Scell resource request acknowledgement message from the target serving node, it indicates that the user equipment that supports the carrier aggregation completes the Scell resource request, and the source serving node requests the acknowledgement message in the Scell resource. According to the service in the cell and the load situation of each frequency point, select a most suitable frequency point and corresponding uplink random access physical resource block information; in general, the source service node is most likely to select the highest priority.
