Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for optimizing interaction between base stations of an inactive terminal, and an electronic device.
Background
The generation 5 (5th generation, 5g) specification defines a Radio Resource Control (RRC) Inactive state (RRC-Inactive state) which is a state between a connected (connected) state and an idle (idle) state. In an RRC-Inactive state, an RRC connection between the terminal and a Radio Access Network (RAN) node is released, but a connection is maintained between the RAN node and a Core Network (CN) node. A radio access network Notification Area (RNA) may include one or more base stations or cells.
When the terminal in the inactive state moves from the signal coverage area of the last neighboring base station to the signal coverage area of the current base station, in some cases, the terminal needs to send an RRC recovery request to the current base station. After receiving the RRC recovery request, the current base station interacts with the neighboring base station to obtain context information of the terminal. However, in the process of the two base stations interacting (XN interacting), if the neighboring base station determines that the current base station is in the same RNA as the current base station, the neighboring base station will reject the context information acquisition request sent by the current base station. The interaction process of rejecting the context information acquisition request belongs to a meaningless interaction process, increases the load of base stations, influences Key Performance Indicators (KPIs) between the base stations, and increases the time length for the terminal to confirm whether to recover from an inactive state to a connected state.

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.
In a New Radio (NR) communication System, when an inactive terminal moves to a signal coverage of a New base station (current base station), the terminal receives broadcast Information of the New base station, and reads an RNA identity of an RNA to which the New base station belongs from a System Information Block Type1 (SIB 1) in the broadcast Information. Wherein, the RNA identification of the RNA to which the new base station belongs is indicated by a RAN area code (RAN _ REG) parameter in SIB 1. However, since the ranac parameter is an optional field in SIB1, in some cases, the ranac parameter is not carried in SIB 1. In this case, the terminal may transmit an RRC recovery request to the new base station. After receiving the RRC recovery request, the new base station interacts with the last neighboring base station where the terminal resides to obtain context information of the terminal. In the process of interaction of the two base stations, when the adjacent base station judges that the adjacent base station and the new base station are in the same RNA, the adjacent base station rejects the context information acquisition request of the new base station.
Fig. 1 is a schematic flow diagram of a neighboring base station rejecting a Context information acquisition Request of a new base station provided in this embodiment, referring to fig. 1, after a terminal moves to a signal coverage of the new base station, the terminal sends an RRC recovery Request (for example, the RRC recovery Request includes an RRC Resume Request or an RRC Resume Request (1)), after the new base station receives the RRC recovery Request, the new base station sends a Context information acquisition Request (i.e., a Retrieve UE Context Request) to an upper base station (i.e., a neighboring base station) where the terminal resides, after the neighboring base station receives the Context information acquisition Request, if it detects that the new base station and the neighboring base station belong to the same RNA, the new base station rejects the Context information acquisition Request, and sends a Context information acquisition Request rejection information (i.e., a Retrieve UE Context Request) to the new base station, after the new base station receives the Context information acquisition Request rejection information, the new base station sends an RRC release message (i.e., an rrcelease) to the terminal. This refused interaction process increases the load on the base stations and affects the KPI between base stations.
To solve this technical problem, fig. 2 is a schematic flowchart of a method for optimizing inter-base station interaction of a terminal in an inactive state at a base station side according to this embodiment, where the method is executed by a base station, and referring to fig. 2, the method includes:
step 201: receiving a Radio Resource Control (RRC) recovery request sent by a non-activated terminal;
specifically, the current base station where the terminal resides receives an RRC recovery request for requesting to transition the terminal from an inactive state to a connected state.
In the method provided in this embodiment, after the terminal in the inactive state moves from the signal coverage of the neighboring base station to the signal coverage of the current base station, the terminal marks "whether there is a second RNA identity of the RNA to which the current base station belongs" in the broadcast information of the current base station in the RRC recovery request, and after receiving the RRC recovery request, the current base station further determines whether to send the context information acquisition request to the neighboring base station according to the mark in the RRC recovery request. Therefore, only when the current base station and the adjacent base station belong to different RNAs is confirmed, the context information acquisition request is sent to the adjacent base station, and the rejected interactive process is avoided.
the neighboring base station is a base station where the terminal resides last time before the current base station.
It should be noted that, the terminal may mark "whether there is a second RNA identity of the RNA to which the current base station belongs" in the broadcast information in two ways, where the two ways include: mode 1, marking by "whether there is preset marking information"; mode 2, marking is performed by "a value of preset marking information as a mandatory field".
Correspondingly, on the base station side, when the mode 1 is specified to be adopted for marking, the step 202a is executed, if the RRC recovery request adds the preset marking information, it indicates that the broadcast information does not have the second RNA identification of the RNA to which the current base station belongs, otherwise, the broadcast information has the second RNA identification. When the marking is performed in the above mode 2, the step 202b is performed, and the RRC recovery request must have the preset marking information, and if the value of the preset marking information in the RRC recovery request is the first preset value, it indicates that the broadcast information does not have the second RNA identification. Therefore, the base station side performs the process 202a or 202b in this step according to whether the mode 1 or mode 2 marking is prescribed.
Further, the preset mark information is in a reserved field of the RRC recovery request. Specifically, the preset flag information is added on the basis of the existing RRC recovery request, and the preset flag information may be added in a reserved field of the RRC recovery request, and a celladjranacccheckflag parameter is used as the preset flag information. When the above-described mode 1 is adopted, it is specified that when the celladjranacccheckflag parameter is present, it indicates that the second RNA identification is not present in the broadcast information. Further, when the CellAdjRanacCheckFlag parameter is present, the value at the time of the CellAdjRanacCheckFlag parameter may be set to true. When the method 2 is adopted, it is specified that when the value of the CellAdjRanacCheckFlag parameter is the first preset threshold, it indicates that the second RNA flag does not exist in the broadcast information, and when the value of the CellAdjRanacCheckFlag parameter is the second preset threshold, it indicates that the second RNA flag exists in the broadcast information.
It should be noted that, if the preset flag information is set in the reserved field of the RRC recovery request, it is not necessary to perform excessive adjustment on the original structure of the RRC recovery request, and the flag process of the above-mentioned mode 1 or mode 2 can be implemented under the condition that the minimum change is guaranteed in the prior art.
The first preset threshold and the second preset threshold may have following exemplary values: the first preset threshold value is 1, and the second preset threshold value is 0; the first predetermined threshold is TRUE, and the second predetermined threshold is FALSE or null.
When the method 1 is adopted, if the RRC recovery request has the preset flag information, whether to send the context information acquisition request to the neighboring base station is determined according to the configuration information and the RRC recovery request. When the method 2 is adopted, if the value of the preset marking information in the RRC recovery request is the first preset value, whether to send a context information acquisition request to the neighboring base station is determined according to the configuration information and the RRC recovery request.
Since this step does not have the second RNA identity in the broadcast information, a further judgment process is performed. Therefore, the situation that the sending context information acquisition request is rejected by the adjacent base station is avoided, and the meaningless interaction process among the base stations is reduced. Meanwhile, the current base station can directly send RRC release information to the terminal when judging that the current base station and the adjacent base station belong to the same RNA. Compared with the mode that the RRC release message is sent to the terminal after the context information acquisition request is refused, the mode of sending the RRC release message shortens the time length for the terminal to confirm whether to recover from the inactive state to the connected state.
The embodiment provides an inter-base station interaction optimization method for an inactive state terminal, wherein when the inactive state terminal sends an RRC recovery request, the inactive state terminal marks whether a second RNA identifier of a current base station exists in broadcast information through preset marking information, so that the current base station can further determine whether to send a context information acquisition request to an adjacent base station under the condition that the second RNA identifier does not exist in the broadcast information. So that the context information acquisition request is not transmitted in case it is determined that the context information acquisition request will be rejected by the neighboring base station. The refused interactive process is avoided, the load of the base stations is reduced, the KPI between the base stations is favorably improved, and meanwhile, the time for the terminal to confirm whether to recover from the non-activated state to the connected state is shortened. The refused interactive process is avoided, the load of the base stations is reduced, the KPI between the base stations is favorably improved, and meanwhile, the time for the terminal to confirm whether to recover from the non-activated state to the connected state is shortened.
Further, in the above steps 202a and 202b, the determining whether to send the context information acquisition request to the neighboring base station according to the configuration information and the RRC recovery request includes:
acquiring an RNA identifier of a notification area of a first radio access network according to the RRC recovery request, and acquiring a second RNA identifier according to the configuration information; (ii) a
If the first RNA identification is consistent with a second RNA identification in the configuration information, sending an RRC release message to the terminal;
if the first RNA identification is inconsistent with the second RNA identification, sending the context information acquisition request to the adjacent base station;
the first RNA identification is an identification corresponding to the RNA of the adjacent base station, and the second RNA identification is an identification corresponding to the RNA of the current base station where the terminal resides.
The second RNA identity of the RNA to which the current base station belongs is configured in the configuration information of the current base station, and the RRC recovery request includes the first RNA identity of the RNA to which the last base station (i.e., the neighboring base station) where the terminal resides belongs, so that whether the current base station and the neighboring base station belong to the same RNA can be determined according to the configuration information of the current base station and the RRC recovery request.
Specifically, the current base station sends the context information acquisition request to the neighboring base station only when the first RNA identifier of the neighboring base station is inconsistent with the second RNA identifier of the current base station. Because the first RNA identification is inconsistent with the second RNA identification, the adjacent base station and the current base station belong to different RNAs, the adjacent base station can not reject the context information acquisition request at the moment, and the meaningless interaction process between the base stations is avoided. Meanwhile, when the first RNA identification of the adjacent base station is consistent with the second RNA identification of the current base station, the RRC release message can be immediately sent to the terminal without an interactive process among the base stations, and the time length for the terminal to confirm whether to recover from the non-activated state to the connected state is shortened.
Further, on the basis of the above embodiments, the method further includes:
when the preset mark information is an optional field in the RRC recovery request, if the preset mark information is added in the RRC recovery request, adding a second RNA identification in the configuration information into broadcast information;
and when the preset marking information is a necessary field in the RRC recovery request, if the value of the preset marking information is the first preset value, adding a second RNA mark in the configuration information into the broadcast information.
And adding a second RNA identification in the broadcast information, namely representing the second RNA identification by a ranac parameter in SIB1 of the broadcast information.
The following description is provided in connection with specific protocols: the broadcast information of the current base station represents the second RNA identification of the RNA to which the base station belongs through the ranac parameter in the SIB 1. In a protocol describing a Public Land Mobile Network (PLMN) -identity infolist information element, description information about a ranac parameter is as follows:
as can be seen from the above description, the ranac parameter is an optional field in the broadcast information of the base station. Therefore, the base station may not carry the ranac parameter in the broadcast information. When the ranac parameter does not exist in the broadcast information, the terminal cannot determine whether the current base station where the terminal resides and the last base station where the terminal resides (i.e. the neighbor base station) belong to the same RNA.
When the terminal cannot acquire the second RNA identity of the current base station, an RRC recovery request is sent to the current base station, and the following is a partial description of the RRC recovery request (RRCResumeRequest (1)) in the protocol:
the following is a partial description of the protocol for RRC recovery request (RRCResumeRequest):
it can be seen that in any RRC recovery request, there is a 1 byte reserved field in the RRC recovery request. In the method provided in this embodiment, when the terminal sends the RRC recovery request to the current base station, the reserved field is used to mark whether the second RNA identity exists in the broadcast information in the above-mentioned mode 1 or mode 2. After receiving the RRC recovery request, the current base station may determine whether the second RNA identity exists in the broadcast message through the reserved field.
Specifically, for the above mode 1, the preset flag information is a celladjranacaccheckflag field.
As an example, the following is a partial description of the RRC recovery request (RRCResumeRequest (1)) after adding the celladjranacaccheckflag field:
the following is a partial description of the RRC recovery request (RRCResumeRequest) after adding the celladjranacccheckflag field:
further, on the basis of the above embodiments, the method further includes:
when the preset mark information is an optional field in the RRC recovery request, if the preset mark information is not added to the RRC recovery request, sending the context information acquisition request to the adjacent base station;
when the preset marking information is a necessary field in the RRC recovery request, if the value of the preset marking information is a second preset value, sending the context information acquisition request to the adjacent base station;
wherein the first preset value is different from the second preset value.
When the marking is performed by the above method 1, if the RRC recovery request does not have the preset marking information, it indicates that the broadcast information has the second RNA identifier, and the second RNA identifier is inconsistent with the first RNA identifier. When the marking is performed by the above method 2, if the value of the preset marking information in the RRC recovery request is the second preset value, it indicates that the broadcast information has the second RNA identifier, and the second RNA identifier is inconsistent with the first RNA identifier. In both cases, the neighboring base station does not reject the context information acquisition request sent by the current base station, so in both cases, the current base station can directly send the context information acquisition request to the neighboring base station.
Specifically, the purpose of sending the context information acquisition request to the neighboring base station by the current base station is to perform "RNA update", and the process of "RNA update" includes:
the current base station sends the context information acquisition request to the adjacent base station;
the current base station receives response information of an adjacent base station to the context information acquisition request, and sends a request for updating the connection state of the terminal to a core network so that the core network updates the connection state of the terminal;
and the current base station receives the information which is sent by the core network and successfully updates the connection state of the terminal.
When the above mode 1 is adopted, fig. 3 is a schematic flow chart of the base station side processing the RRC recovery request provided in this embodiment, and with reference to fig. 3, the method includes:
step 301: the base station side receives the RRCResumRequest (1) message;
step 302: the base station side judges whether celladjranacccheck flag in RRCResumeRequest (1) is tube (i.e. whether celladjranacccheck exists), if yes, step 303 is performed: if the CellAdjRanacCheckFlag does not exist, jumping to the end;
step 303: the base station side compares the ranac parameter (configuration information) configured by itself with the ranac parameter configured by the neighboring base station in the neighboring cell relation indicated by the rrcresemequest, if so, the step 304a is executed, and if not, the step 304b is executed.
Step 304b: the base station performs a normal RNA update procedure, and then executes step 305.
Step 305: and the base station side updates the SIB1 content, increases the ranac parameter and ends the processing flow aiming at the field.
Since the terminal sends the RRCResumeRequest (1) message to the base station only when there is no ranac parameter in the SIB1 content of the broadcast information or the ranac parameter in the SIB1 content is not consistent with the ranac parameter of the last base station where the terminal resides, if it is determined in the above step 302 that celladjranacaccheckflag does not exist, it indicates that the ranac parameter in the SIB1 content is not consistent with the ranac parameter of the last base station where the terminal resides. At this time, a context information acquisition request needs to be sent to an upper base station. Performing a normal RNA renewal protocol in step 304b refers to the "RNA renewal" process described above.
Corresponding to the methods provided in the foregoing embodiments, fig. 4 is a flowchart illustrating a method for optimizing interaction between base stations of a terminal-side terminal in an inactive state according to this embodiment, where the method is executed by a terminal, and it should be noted that the terminal executing the method provided in this embodiment may be User Equipment (UE), an access terminal, a UE unit, a UE station, a mobile station, a remote terminal, a mobile device, a UE terminal, a wireless communication device, a UE agent, or a UE apparatus. The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, a terminal in a future 5G network or a terminal in a future evolved PLMN network, and the like. Referring to fig. 4, the method includes:
step 401: the non-activated terminal receives the broadcast information of the current base station and judges whether to send an RRC recovery request to the current base station or not according to the received broadcast information;
when the terminal moves from the signal coverage area of the adjacent base station to the signal coverage area of the current base station, the terminal receives the broadcast information of the current base station. The second RNA identity of the RNA to which the current base station belongs can typically be read by the ranac parameter in SIB1 in the broadcast message. And when the broadcast information does not carry the ranac parameters or the carried second RNA identification in the ranac parameters is inconsistent with the first RNA identification of the adjacent base station, sending an RRC recovery request to the adjacent base station.
the second RNA mark is a mark corresponding to the RNA of the current base station; the first preset value is different from the second preset value.
When the method 1 is adopted, the terminal marks whether the second RNA identity exists in the broadcast information through the step 402a, and the base station performs the judgment process through the step 202 a; or, when the method 2 is adopted, the terminal marks whether the second RNA flag exists in the broadcast information through the step 402b, and the base station performs the determination process through the step 202 b.
Further, the step 401 includes:
the method for the non-activated terminal to receive the broadcast information of the current base station and judge whether to send the RRC recovery request to the current base station according to the received broadcast information comprises the following steps:
the terminal in the non-activated state receives the broadcast information of the current base station and judges whether a second RNA mark exists in the broadcast information or not;
if the second RNA identification exists in the broadcast information, judging whether the second RNA identification is consistent with the first RNA identification, if so, not sending an RRC recovery request, otherwise, sending the RRC recovery request;
if the second RNA identification does not exist in the broadcast information, sending an RRC recovery request;
wherein, the first RNA mark is a mark corresponding to the RNA of the adjacent base station; and the adjacent base station is the base station where the terminal resides last time before the current base station.
In the method for optimizing interaction between base stations of an inactive state terminal provided in this embodiment, when the inactive state terminal sends an RRC recovery request, the inactive state terminal marks whether a second RNA identifier of a current base station exists in broadcast information through preset marking information, so that the current base station can further determine whether to send a context information acquisition request to an adjacent base station under the condition that the second RNA identifier does not exist in the broadcast information. So that the context information acquisition request is not sent when it is determined that the context information acquisition request will be rejected by the neighboring base station. The refused interactive process is avoided, the load of the base stations is reduced, the KPI between the base stations is favorably improved, and meanwhile, the time for the terminal to confirm whether to recover from the non-activated state to the connected state is shortened.
When the above mode 1 is adopted, fig. 5 is a schematic flow diagram of processing an RRC recovery request by a terminal side provided in this embodiment, and referring to fig. 5, the method includes:
step 501: the terminal moves to other base stations in an Inactive state, and reads the SIB1 message of the current resident cell;
step 502: judging whether the SIB1 carries a ranac parameter, if so, executing a step 503b, otherwise, executing a step 503a;
step 503a: if the read SIB1 message does not contain Ranac parameter, then set CellAdjRanacCheckFlag as Ture in RRCRESumeRequest (1)
The method provided by the embodiment makes full use of the reserved field in the protocol for the abnormal condition that the base station does not configure the ranac optional field in the SIB1, effectively reduces the inter-station XN interaction flow and shortens the unnecessary connection state holding time of the terminal on the premise of not adding a new field; on the other hand, through the field, the base station can timely find itself abnormal (that is, the ranac parameter is not configured in SIB1 of the broadcast message), so as to repair.
