Description

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

technical field

The present invention relates to the technical field of mobile communication, in particular to a carrier aggregation access control method between base stations, an access method, a device, a base station, user equipment and a mobility management entity.

Background technique

With the rapid development of mobile communication systems, the future long-term evolution (LTE, Long term Evolution)/enhanced long-term evolution (LTE-A, Long-term Evolution Advanced) system needs to provide higher speed and wider coverage of service transmission, In order to meet people's demand for a higher rate of communication services. Due to the increasingly scarce spectrum resources, in the prior art, in order to further improve the spectrum efficiency and system throughput of the system, a new carrier aggregation (CA, Carrier Aggregation) technology is proposed. This carrier aggregation technology has been adopted as the LTE-A One of the important system enhancement technologies in the evolution version of the system.

Currently, regarding the progress of carrier aggregation in the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) standard, the signaling and requirements defined by the carrier aggregation technology in the standard are mainly for intra-eNB scenarios, that is, for Both the primary cell and the secondary cell served by a user equipment (UE, User Equipment) share a "site (site)", and are mainly controlled by a base station.

However, the scenario of carrier aggregation is not limited to the case of intra-eNB. In the actual carrier aggregation application scenario, there will be a situation where the primary cell and the secondary cell "do not share the same site". This situation is carrier aggregation between base stations. Carrier aggregation between base stations can be divided into carrier aggregation between macro base stations, and carrier aggregation between macro base stations and low power nodes (LPN, low powernode). In the current standard, there is less content involved in the carrier aggregation between base stations. For the access control algorithm, since the addition and deletion of the secondary cell by the primary cell needs to be carried out through the X2 interface or the S1 interface. Signaling interaction, therefore, the flow of access control is completely different from intra-eNB.

Therefore, in the prior art, since the primary cell and the secondary cell do not share the same site, the primary cell knows little information about the resources of the secondary cell. How to perform signaling interaction between the primary cell and the secondary cell to effectively ensure that the UE can more effectively Effectively accessing the network, improving the success rate of UE random access, and then improving the throughput and user experience of the entire network are currently technical problems to be solved.

In order to facilitate the understanding of those skilled in the art, specific examples are used below to illustrate.

Please refer to FIG. 9 . FIG. 9 is a flowchart of a first application example of a carrier aggregation access control method between base stations provided by an embodiment of the present invention. In this embodiment, it is assumed that there is an X2 interface connection between the source eNB (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 supporting carrier aggregation, the source serving node is a serving node belonging to the primary cell, and the target serving node is a serving node belonging to the secondary cell, specifically including:

Step 901: The user equipment supporting carrier aggregation sends an RRM-related measurement report to the source serving node to which the primary cell belongs (in this embodiment, eNB1 to which the primary cell Pcell belongs is taken as an example);

Wherein, the RRM-related measurement report is the RRM measurement of the user equipment at each frequency point and each node.

Wherein, the content in the measurement report may include RSRP measurement results, RSRQ measurement results, or other measurement results. This embodiment takes the RSRP measurement result as an example, and its reporting form is as follows, but is not limited thereto:

For F1 frequency point: the RSRP measurement result of cell i1 is RSRP1_i1, and the RSRP measurement result of cell j1 is RSRP1_j1...;

For F2 frequency point: the RSRP measurement result of cell i2 is RSRP2_i2, and the RSRP measurement result of cell j2 is RSRP2_j2...;

…

For the Fx frequency point: the RSRP measurement result of cell ix is RSRPx_ix, and the RSRP measurement result of cell jx is RSRPx_jx....

Step 902: The source serving node (such as eNB1 to which the primary cell belongs) sends a secondary cell (Scell) resource request message to the target serving node (such as eNB2 to which the secondary cell belongs) based on the RRM measurement report amount.

The secondary cell resource request message includes: the eNB1 to which the primary cell belongs selects the Scell frequency point list suitable for the user equipment supporting carrier aggregation selected by the eNB2 to which the secondary cell belongs, and optionally, the frequency points in the Scell frequency point list ( Secondary cell frequencies) are sorted according to the priority of user service quality, which can be sorted from high to low or from low to high.

The Scell frequency point list can also be called "Scell frequency point priority list", and its form can be: {frequency point i, frequency point j, ... frequency point k, ...}, which can be expressed as {Fi, Fj, ...Fk, ...}, the priority satisfies: frequency point i>frequency point j>...frequency point k.... But it is not limited to this, and it can also be in other forms, which are not limited in this implementation.

Step 903: After the target serving node receives the Scell resource request message, according to the load situation and business situation of its own multiple frequency points, and the priority ranking situation given by the primary cell (in this example, the priority ranking information is included as For example), a most suitable frequency point and an uplink random access physical resource block (PRB, Physical Resource Block) resource of the frequency point are selected for the user equipment supporting carrier aggregation.

Step 904: The target service node sends a Scell resource request confirmation message to the source service node through a Scell resource request confirmation message, and the Scell resource request confirmation message includes the most suitable frequency point and uplink PRB resources;

Among them, in this embodiment, the most suitable frequency point and uplink PRB resource, the target serving node (secondary cell) can send the source serving node (primary cell) through the Scell resource request confirmation message, but it is not limited to this Scell resource request confirmation The message may also be through other messages, which is not limited in this embodiment.

In this embodiment, the Scell resource request acknowledgment message may be sent in the form of: {frequency point m, uplink random access physical resource block information m}, which can be expressed as {Fm, UL RACH PRB information m}.

Step 905: The source serving node sends the Scell configuration information to the user equipment supporting carrier aggregation through an RRC connection reconfiguration message; the Scell configuration information includes: physical cell identifier PCI, frequency point, uplink random access physical resource block .

That is to say, after the source service node receives the Scell resource request confirmation message sent by the target service node, it means that the user equipment supporting carrier aggregation has completed the Scell resource request, and the source service node configures the corresponding Scell Information, notified to the user equipment supporting carrier aggregation through an RRC connection reconfiguration message (but not limited to this message, this embodiment takes this as an example), the RRC connection reconfiguration message includes the Scell configuration information and uplink PRB resources.

Wherein, the Scell configuration information includes: {Physical cell identity PCI, frequency point m, uplink random access physical resource block information m}, which can be expressed as {PCI, Fm, UL RACH PRB information m}.

Step 906: After receiving the Scell configuration information sent by the source serving node, the user equipment initiates a random access request on the secondary cell based on the frequency point and uplink PRB resources, and completes the establishment of the Scell radio link;

That is to say, the user equipment completes the access control under the inter-eNB.

Certainly, in another embodiment, the difference between this embodiment and the embodiment described in FIG. 9 is that: the secondary cell (Scell) resource request message includes: the source serving node to which the primary cell belongs requests the secondary cell A secondary cell frequency allocated by the target serving node to which the user equipment belongs, and a corresponding uplink random access physical resource block resource. After receiving the secondary cell resource request message, the target serving node allocates a secondary cell frequency point and a corresponding uplink random access physical resource block resource for the user equipment according to its own service and load conditions. The secondary cell resource request confirmation message sent by the target serving node to the source serving node includes: a frequency point of the secondary cell allocated by the target serving node to the user equipment, and corresponding uplink random access physical resource block resources.

Step 1004: The target serving node sends the multiple appropriate frequency points selected for the user equipment and the uplink PRB resources corresponding to each frequency point to the source serving node through a Scell resource request confirmation message;

In this step, the above-mentioned multiple appropriate frequency points and the uplink PRB resources corresponding to each frequency point may request confirmation messages through Scell resources, but are not limited thereto, and may also be sent through other messages, which are not limited in this embodiment.

The sending form of the Scell resource request confirmation message is: {(frequency point i, uplink random access physical resource block information i), (frequency point j, uplink random access physical resource block information j), ..., (frequency point k , uplink random access physical resource block information k), ...}, which can be expressed as {(Fi, UL RACH PRB information i), (Fj, UL RACH PRB information j), ... (Fk, UL RACH PRB information k), ...}.

Step 1005: The source serving node selects a 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 conditions of each frequency point;

That is to say, after the source serving node receives the Scell resource request acknowledgment message from the target service node, it indicates that the user equipment supporting carrier aggregation has completed the Scell resource request, and the source service node receives the Scell resource request acknowledgment message. According to the business in the cell and the load of each frequency point, select a most suitable frequency point and the corresponding uplink random access physical resource block information; generally, the source serving node is most likely to select the highest priority That frequency point and corresponding PRB information.

Step 1006: The source serving node sends a corresponding selected Scell frequency point and corresponding uplink PRB resource to the user equipment supporting carrier aggregation through an RRC connection reconfiguration message; wherein, the Scell frequency point and the corresponding uplink PRB resource PRB resources are called Scell configuration information.

The information contained in the Scell configuration information includes: {physical cell identity, frequency point m, uplink random access physical resource block information}, which can be expressed as {PCI, Fm, UL RACH PRB information}. But it is not limited to this.

Step 1007: After receiving the Scell configuration information sent by the source serving node, the user equipment makes a random access request on the secondary cell based on the configured frequency point information and uplink PRB resources, and completes the establishment of the Scell radio link.

That is, the clubhouse, the user equipment completes the access control under the inter-eNB.
