Description

Secondary base station allocation method and device

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a secondary base station allocation method and a secondary base station allocation device.

Background

3GPP L TE is a technology for high-speed packet communication, and many proposals have been made for the L TE target of reducing user and provider costs, improving service quality, and expanding and increasing coverage system capacity 3GPP L TE will reduce cost per bit, increase service availability, flexible use of frequency bands, simple structure, open interface, and low power consumption of terminals as more advanced requirements.

Small cells (small cells) using low power nodes are considered promising to cope with mobile traffic proliferation, especially for hotspot deployment in indoor and outdoor scenarios. Low power nodes generally mean nodes with lower transmission power than the macro node and Base Station (BS) classes, e.g., pico and femto evolved node BS (enbs) are applicable. Small cell enhancements for evolved UMTS terrestrial radio access (E-UTRA) and evolved UMTS terrestrial radio access network (E-UTRAN) will focus on additional functionality to enhance performance in indoor and outdoor hot spot areas using low power nodes.

In small cell architectures, a UE may simultaneously transmit and receive data at two base stations, which is referred to as dual-connectivity. Of the two base stations, only one base station is responsible for sending Radio Resource Control (RRC) messages to the UE and interacting with a core network control plane entity (MME), which is called a master base station (MeNB), and the other base station is called a secondary base station (SeNB). The UE has a cell which is a primary cell (Pcell) of the UE at a main base station, the RRC message is sent to the UE through the primary cell, and other cells are secondary cells (Scell). One cell of the UE in the Scell of the secondary base station is a secondary base station primary cell pScell. There is an uplink physical layer control channel on the pScell, and there is no uplink physical layer control channel on other scells. The master base station cell group is the MCG and the secondary base station cell group is the SCG. The resources of the UE side auxiliary base station cell group are configured by the auxiliary base station, and the auxiliary base station sends the configuration of the UE to the main base station through the RRC container and then sends the configuration to the UE by the main base station. The primary base station does not parse the RRC container or parse the RRC container without changing the configuration in the RRC container.

In existing 3GPP L TE networks, the SeNB addition procedure is initiated by the MeNB and used to establish a connection with the UE at the SeNB in order to provide UE. the RRC from the SeNB, which is used to add at least the first cell (PSCell) of the SCG.

Fig. 1 is a signaling interaction diagram of a method for adding an SeNB in a 3GPP protocol provided in the prior art, as shown in fig. 1, including:

step 101: the MeNB communicates a SeNB addition request signal, which may contain operating environment-related or other UE environment-related information, address information for data forwarding (if applicable) and configuration information for the requested SCG, including the SeNB reconfiguration based on the result of UE capability coordination. An SCG change indication is included if the SCG changes.

The SeNB responds to the SeNB modify request acknowledge message, which may include the SCG radio resource configuration information in NR RRC configuration information and address information for data forwarding (if applicable), in the case of a change in SCG, there is no change in anonymous E-RABs for configuring MCG split operation options, the SeNB provides the MeNB with a new D L GTP TEID, the MeNB sends D L PDCP PDUs to the SeNB with the previous D L GTP TEID continuously until PDCP re-establishment or PDCP data recovery, and starts using the new D L GTP TEID from the PDCP re-establishment or recovery data.

Step 103: the MeNB initiates an RRC connection configuration procedure, including NR RRC configuration information.

Step 104: the UE applies the new configuration and replies to the RRC connection configuration completion including a response to the NR RRC message. A reconfiguration procedure failure may occur if the UE is unable to comply with (part of) the configuration included in the RRC connection configuration complete signal.

Step 105: after the recombination is successfully completed, the successful result of the process is displayed in a complete message reconstructed by the SeNB.

Step 106: a random access procedure is established.

Step 107: the SeNB sends data to the MeNB.

Step 108: the MeNB sends data to the SeNB.

Step 109: a path update procedure is executed.

However, in the prior art, any UE needs to be allocated with a SeNB again after the connection of the MeNB, the whole allocation process is complex in procedure and large in delay, and the data transmission of the UE is easily interrupted, so that the data transmission quality is influenced.

Therefore, how to improve the efficiency of adding the SeNB and thus improve the processing efficiency of the whole service is an urgent issue to be solved today.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 2 is a schematic flow chart of a method for allocating a secondary base station according to an embodiment of the present invention, as shown in fig. 2, the method includes:

step 201: acquiring a terminal establishing connection with a local master base station (MeNB);

specifically, the terminal UE sends a request for establishing a connection to the local master base station MeNB, the local MeNB establishes a connection with the UE after receiving the request, and after the connection is established, the local MeNB obtains the UE, and then performs negotiation between the local MeNB and the MME, and allocates a corresponding S1 access point identifier to the UE.

Step 202: according to signaling interaction information of the terminal and the local MeNB, if the connection attribute corresponding to the terminal is judged to be switched connection, sending a query request to an MME, wherein the query request comprises an S1 access point identifier corresponding to the terminal, so that the MME allocates a target SeNB for the terminal and sends the target SeNB to the local MeNB;

specifically, signaling interaction is required to be performed for a plurality of times during the connection establishment process between the UE and the local MeNB, and the local MeNB may determine a connection attribute of the UE connected to the local MeNB according to the signaling interaction information, where the connection attribute may be a first connection or a handover connection, and the handover connection is to be switched from another MeNB to the local MeNB to establish connection with the local MeNB. If the local MeNB determines that the connection attribute is handover connection, it sends an inquiry request to the MME to inquire whether there is an SeNB that maintains connection with the UE in the MME, because there may be an SeNB that is continuously used in the handover connection, it should be noted that the inquiry request includes an S1 access point identifier (S1APID) corresponding to the UE, and may also include other information, which is not specifically limited in this embodiment of the present invention. If the MME judges that the SeNB maintaining the connection exists according to the S1APID, the MME does not need to interact with other network elements, only needs to continue using the SeNB before the switching according to the data stored by the MME, namely, the connection between the SeNB and the terminal is continuously maintained, and the SeNB is taken as a target SeNB. And if the MME judges that the SeNB which is connected with the terminal does not exist, allocating a target SeNB for the terminal. It should be noted that an information table in which S1 APIDs corresponding to all terminals are connected to an SeNB is stored in the MME, and if the information table has a correspondence relationship between S1 APIDs corresponding to the UE and the SeNB, it indicates that an SeNB that is connected to the UE exists, otherwise, it does not exist.

Step 203: and receiving the target SeNB sent by the MME to complete the allocation of the SeNB of the terminal.

Specifically, the local MeNB receives the target SeNB sent by the MME, so as to know that the corresponding SeNB has been allocated to the UE.

According to the embodiment of the invention, the connection attribute is judged to be the switching connection, and then the query request is sent to the MME so that the MME allocates the target SeNB for the terminal, so that the efficiency of allocating the SeNB for the switching connection is improved, and the processing efficiency of the whole service is improved.

On the basis of the above embodiment, the method further includes:

and if the connection attribute corresponding to the terminal is judged and known to be the first connection, sending an allocation demand message to the MME, wherein the allocation demand message comprises the routing information of the target SeNB, so that the MME sends an allocation processing request to the target SeNB according to the routing information and sends a corresponding confirmation message to the local MeNB according to the processing result of the target SeNB.

Specifically, the local MeNB may determine, according to the signaling interaction information, that the connection attribute of the UE connected to the local MeNB is the first connection, which indicates that the UE has not established a connection with other menbs before the first connection, and therefore, there is no possibility that there is an SeNB that remains connected to the UE, and a SeNB needs to be newly allocated to the UE. At this time, the local MeNB sends an allocation requirement message to the MME, where the allocation requirement message includes routing information of the target SeNB, where the routing information includes an SeNB identifier and a tracking area code TAI, and may also include an S1APID corresponding to the UE, which is not specifically limited in this embodiment of the present invention. After receiving the allocation demand message, the MME sends an allocation processing request to the corresponding target SeNB according to the routing information of the target SeNB, wherein the allocation processing request comprises the S1APID corresponding to the UE, after receiving the allocation processing request, the target SeNB performs corresponding processing operation according to the S1APID in the allocation processing request to obtain a processing result, and sends the processing result to the MME, and the MME sends a corresponding confirmation message to the local MeNB according to the processing result. That is, when the target SeNB is successfully processed, indicating that the connection with the UE is successful, the MME sends an addition confirmation message to the local MeNB; when the target SeNB fails to process, the MME sends an add failure message to the local MeNB.

The embodiment of the invention judges that the connection attribute is the switching connection, sends the query request to the MME, and if the SeNB which is connected with the terminal exists, the method continues to use without reallocation, thereby improving the efficiency of allocating the SeNB for the switching connection and improving the processing efficiency of the whole service.

Fig. 3 is a schematic flow chart of a secondary base station allocation method according to another embodiment of the present invention, as shown in fig. 3, the method includes:

step 301: receiving an inquiry request sent by a local MeNB, wherein the inquiry request comprises an S1 access point identifier corresponding to a terminal;

specifically, the MME receives an inquiry request sent by the local MeNB, where the inquiry request includes the local MeNB and the S1APID allocated by the MME to the terminal UE, and may further include other information. It should be noted that the query request sent by the local MeNB is based on the premise that, after the terminal UE establishes connection with the local MeNB, the local MeNB determines that the connection attribute is handover connection. In order to ensure dual connectivity, the UE needs to connect to one SeNB in addition to the local MeNB, and therefore, the local MeNB needs to acquire a target SeNB connected to the UE from the MME.

Step 302: and allocating a target SeNB for the corresponding terminal according to the access point identifier of S1, and sending the target SeNB to the local MeNB to complete the allocation of the SeNB of the terminal.

Specifically, the MME allocates a target SeNB for the corresponding terminal according to the received S1APID, where the MME may determine whether there is an SeNB that is connected to the terminal according to the S1APID, if so, the SeNB is the target SeNB, and if not, allocates the target SeNB for the terminal according to an internal preset algorithm. And after the target SeNB is allocated to the terminal, the target SeNB is sent to the local MeNB.

According to the embodiment of the invention, the target SeNB is allocated to the terminal through the MME, and the local MeNB is not required for allocation, so that the processing pressure of the local MeNB is reduced, and the allocation success rate is improved.

On the basis of the foregoing embodiment, the allocating a target SeNB for a corresponding terminal according to the access point identifier of S1 and returning the target SeNB to the local MeNB includes:

and if the situation that the SeNB which is connected with the terminal is judged to exist according to the S1 access point identifier, taking the SeNB as a target SeNB, and returning the target SeNB to the local MeNB.

Specifically, after receiving an inquiry request sent by the local MeNB, the MME determines, according to the S1APID, whether there is an SeNB that is in connection with the UE, and if the MME determines that there is an SeNB that is in connection with the UE according to the S1APID, the MME does not need to interact with other network elements, and only needs to follow the SeNB before handover according to data stored by the MME itself, that is, continue to maintain the connection between the SeNB and the terminal, use the SeNB as a target SeNB, and send the target SeNB to the local MeNB, so as to inform the local MeNB that the local MeNB has allocated a corresponding target SeNB for the UE. It should be noted that an information table in which S1 APIDs corresponding to all terminals are connected to an SeNB is stored in the MME, and if the information table has a correspondence relationship between S1 APIDs corresponding to the UE and the SeNB, it indicates that an SeNB that is connected to the UE exists, otherwise, it does not exist. And if the MME can not allocate the target SeNB for the terminal, sending a failure reason to the local MeNB.

The embodiment of the invention judges that the connection attribute is switched connection, sends the query request to the MME, and if the SeNB which is connected with the terminal exists, the method continues to use without reallocation, thereby improving the efficiency of switching connection and allocating the SeNB, further improving the processing efficiency of the whole service, and reducing the processing pressure of the MeNB and the SeNB by centralized control of the MME.

On the basis of the above embodiment, the method further includes:

if judging that no SeNB which is connected with the terminal is existed according to the S1 access point identifier, allocating a target SeNB for the terminal;

sending an allocation processing request to the target SeNB to enable the target SeNB to process the allocation processing request;

and if the processing result returned by the target SeNB is successful, receiving an allocation confirmation message sent by the target SeNB, and sending an addition confirmation message to the local MeNB, wherein the addition confirmation message comprises the target SeNB.

Specifically, if the MME determines that there is no SeNB remaining connected to the UE according to the S1APID, the MME allocates a target SeNB to the UE through an internal preset algorithm, and sends an allocation processing request to the target SeNB, it should be noted that the allocation processing request at least includes the S1 APID. And the target SeNB performs corresponding processing after receiving the allocation processing request, and returns a processing result to the MME, and the MME sends a corresponding confirmation message to the local MeNB according to the processing result.

And if the processing result returned by the target SeNB is successful, the target SeNB sends an allocation confirmation message to the MME, wherein the allocation confirmation message comprises the S1APID, the routing information of the local MeNB and the information related to the accepted and rejected bearer of the target SeNB, and the routing information of the local MeNB includes the local MeNB ID and the TAI. After receiving the allocation confirmation message sent by the target SeNB, the MME sends an addition confirmation message to the corresponding local MeNB according to the routing information in the allocation confirmation message, wherein the addition confirmation message at least includes the S1APID and the target SeNB to inform the local MeNB that the target SeNB is allocated to the terminal corresponding to the S1 APID.

The embodiment of the invention is centrally controlled by the MME, allocates the target SeNB for the UE without processing by the local MeNB, and because the MeNB and the SeNB mainly undertake the processing of air interface services, once the air interface services are large in volume, no enough resources are always available for processing other tasks, so that the signaling between the MeNB and the SeNB is lost. And the MME is adopted for centralized control, so that the processing pressure of the MeNB and the SeNB is reduced.

On the basis of the above embodiment, the method further includes:

and if the processing result returned by the target SeNB is failure, receiving a distribution failure message sent by the target SeNB, and sending an addition failure message to the local MeNB.

Specifically, if the processing result returned by the target SeNB is a failure, the target SeNB sends an allocation failure message to the MME, where the allocation failure message includes the S1APID, the routing information of the local MeNB, and the failure reason, where the routing information of the local MeNB includes the local MeNB ID and the TAI. After receiving the allocation failure message sent by the target SeNB, the MME sends an addition failure message to the corresponding local MeNB according to the routing information in the allocation failure message, so as to inform the local MeNB of the allocation failure for the terminal corresponding to the S1 APID.

step 404: judging whether a SeNB maintaining connection exists; after receiving the query request, the MME determines whether there is an SeNB that remains connected to the UE, if there is an SeNB that remains connected to the UE, step 405 is executed, otherwise step 406 is executed;

step 405: continuing to maintain the connection with the SeNB; if the MME judges that the SeNB maintaining the connection exists according to the S1APID, the MME does not need to interact with other network elements, only needs to continue using the SeNB before switching according to data stored by the MME, namely, continues to maintain the connection between the SeNB and the terminal, takes the SeNB as a target SeNB, sends the target SeNB to a local MeNB, and ends the process;

step 406: allocating a target SeNB for the UE; if the MME judges that the SeNB which is connected with the UE does not exist according to the S1APID, the MME allocates a target SeNB for the UE through an internal preset algorithm, and then step 408 is executed;
