A mechanism of paging packet is currently in discussion in radio access network (RAN), which is introduced mainly for reducing a false alarm.
A typical case is that all user equipment in one paging occasion (PO) would be alarmed if no paging packet is performed.
In one case, the UEs within the PO have different paging probabilities, then a user equipment with a low paging probability is alarmed incorrectly, resulting in the false alarm and causing excess power consumption.
Hence the paging packet is being considered. At present, carrying of paging packet information is discussed in radio access network 1 (RAN1), which can be placed in downlink control information (DCI), or in paging early indication (PEI).
Regardless of packet solutions employed, both a terminal and a network (a base station, a core network) require agreement on a packet in which the terminal is located in order to properly transmit paging messages to the user equipment.
Referring to
At block S110, historical camping information of an inactive user equipment (UE) is transmitted to a core network device.
The base station includes, but is not limited to, an eNB or a gNB.
The core network device includes, but is not limited to, an access management function (AMF).
When the UE switches from a connected state to an inactive state or after the UE switches from the connected state to the inactive state, the UE may transmit the historical camping information of the inactive UE to the core network device.
The historical camping information may indicate information of a cell and/or a base station in which the UE has camped prior to a current time point.
The historical camping information may also indicate a historical coverage enhancement level of the UE.
For example, the historical coverage enhancement level may include, but is not limited to, an enhancement coverage level used by the UE at last one or more cells in which the UE camps.
For example, the historical coverage enhancement level may at least include a downlink enhancement coverage level and/or an uplink enhancement coverage level used by the UE when releasing a connection prior to entering into an inactive state.
In some embodiments, the historical camping information may also indicate a historical camping request of the UE, for example, a cell or a base station where the UE has been most camped, or, a cell or base station where the UE has been camped for a predetermined length of time.
In this way, the core network device, when paging the inactive UE in an unexpected situation, may accurately page an inactive user equipment desired to be paged based on the historical camping information with as little waking up of other user equipment as possible.
In some embodiments, the historical camping information includes:
The historical camping cell information may indicate: one or more cells in which the inactive UE has camped prior to a current time point. For example, the historical camping cell information at least indicates: a last cell in which the inactive UE camps.
For example, the historical camping cell information may include a list of cells. The list of cells includes one or more cell identifications (IDs). The cell identification may be a physical cell identification (PCI).
For another example, the historical camping information may also include a cell identification and length of camping information in the corresponding cell.
In response to the historical camping cell information including a plurality of cell IDs, the plurality of cell IDs may indicate a plurality of cells in which the UE has recently camped.
The historical camping base station information indicates one or more base stations in which the inactive UE has camped prior to a current time point.
The historical camping base station information may include a base station identification. Alternatively, the historical camping base station information may further include length of camping information.
For example, the historical camping base station information may at least include a base station identification of a last base station in which the inactive UE camps.
In response to the historical camping base station information including base station identifications of a plurality of base stations, the historical camping base station information includes the base station identifications of the plurality of base stations where a plurality of the inactive UE have recently camped.
In short, the historical camping cell information at least indicates last one or more cells in which the inactive UE camps, and/or, the historical camping base station information at least indicates: last one or more base stations in which the inactive UE camps.
Referring to
At block S120, a radio resource control (RRC) inactive transition report including the historical camping information is transmitted to the core network device.
The historical camping information may be the historical camping information in the aforementioned embodiments, and is not described herein.
The RRC inactive transition report may be a report in which the base station informs the core network device that the UE is currently in an inactive state or has entered into an inactive state.
In an embodiment of the present disclosure, the historical camping information is carried in the RRC inactive transition report, as such, when the base station reports a notification of the UE being in the inactive state to the core network device, the historical camping information of the inactive UE is reported synchronously. Thus there is no need to report the historical camping information of the inactive UE with additional signaling.
For example, the RRC inactive transition report may include:
In another embodiment, the historical camping information is indicated using remaining bits within an IE indicating that the UE is in the inactive state and/or that the UE enters or leaves the inactive state.
In some embodiments, the RRC inactive transition report includes a state value.
The block S120 may include:
The state value may be indicated by one or more bits. In order to reduce unnecessary repetitive reporting, in some embodiments, the historical camping information is carried in the RRC inactive transition report only when the state value indicates the UE is in the inactive state.
In response to the UE exiting the inactive state, the base station transmits a RRC inactive transition report notifying the core network device that the UE exits the inactive state, such RRC inactive transition report may be used without carrying the historical camping station information, thus reducing unnecessary bit overhead between the base station and the core network device.
In some embodiments, the RRC inactive transition report may be transmitted by the base station itself to the core network device.
In other embodiments, the RRC inactive transition report may be requested by the core network device. At this point, referring to
At block S100, a request for the RRC inactive transition report from the core network device is received.
For example, an access management function (AMF) transmits the request for the RRC inactive transition report to the base station. The AMF transmits the request for the RRC inactive transition report to an anchor base station of the inactive UE based on context information and/or previously reported historical camping information of the UE.
Upon receiving the request, the base station returns the RRC inactive transition report to the core network device.
When transmitting the RRC inactive transition report to the core network device, the historical camping information of the inactive UE is carried in the RRC inactive transition report.
In some embodiments, the request includes:
For example, the single state reporting request may indicate the base station to send the RRC inactive transition report to the core network device once, such as to report whether a current UE enters into the inactive state or exits from the inactive state.
The subsequent state reporting request may indicate the base station to report a plurality of RRC inactive transition reports to the core network device. After receiving the subsequent state report request, the base station, when the UE enters into or exits from the inactive state, transmits the RRC inactive transition report to the core network device. Consequently, the core network device may receive the plurality of RRC inactive transition reports reported at different time points. The core network device may timely understand a condition of the UE entering the inactive state without having to independently request the RRC inactive transition report from the base station each time.
In some embodiments, the request is the single state reporting request, the historical camping information is included in a RRC inactive transition report responsive to the single state reporting request;
In some embodiments, in response to the request being the single state reporting request, the historical camping information is carried in the RRC inactive transition report for the current request for reporting the report.
In response to the request being the subsequent state reporting request and no change being occurred on the cell or the base station in which the UE camps, the UE may report the RRC inactive transition report each time when the UE enters into or exits from the inactive state. In this scenario, since there is no change in the cell or the base station where the UE camps, the base station does not need to repeatedly report the historical camping information of the inactive UE. Therefore, the history camping information can be carried in the RRC inactive transition report reported for the first time only, reducing unnecessary history camping information.
In an embodiment, the block S110 may include:
The inactive UE may perform cell reselection, as such, one base station may change from a non-anchor base station of the inactive UE to an anchor base station of the inactive UE.
For example, the inactive UE may, after having performed the cell reselection, transmit a connection recovery request including its own UE identification to the base station in a target cell reselected. The base station may, after receiving the connection recovery request, find that the UE is a UE switched over from another cell based on the UE identification, and indicate the UE to be maintained in the inactive state in a connection recovery request response replied to the UE. In this way, the UE completes the cell reselection in the inactive state, and the base station on a network side may know that the cell reselection has occurred, and the base station of the target cell reselected by the UE is a current anchor base station of the inactive UE. The anchor base station may have previously been the non-anchor base station.
In response to one base station being switched from the non-anchor base station to the anchor base station, the base station may acquire the historical camping information of the inactive UE, and report the acquired historical camping information to the core network device.
In an embodiment, after switching from the non-anchor base station to the anchor base station of the inactive UE, the base station may transmit the historical camping information to the core network device through a path transformation request message.
For example, the historical camping information may indicate at least a cell identification of a cell in which the inactive UE currently camps and/or a base station identification of a base station in which the inactive UE currently camps.
Referring to
At block S210, paging assistance information transmitted by a core network device is received. The paging assistance information may be determined based on historical camping information of an inactive user equipment (UE).
The paging assistance information may include at least one of:
For example, the paging range indicated by the first indication information may be smaller than a radio notification area (RNA) of an access network in which the current inactive UE is located, thus reducing transmission of unnecessary paging messages and reducing paging overhead.
The second indication message may indicate that the paging message is not transmitted according to the PEI after the inactive UE performs the cell reselection, thus reducing a false alarm of the PEI for other inactive UEs that are in a same paging packet as the inactive UE, and reducing a power consumption generated by alarming other inactive UEs.
In another embodiment, in a case that the inactive UE belongs to a specific paging packet, after the packet performs the cell reselection, it is indicated to transmit the PEI before transmitting a paging message for paging the inactive UE. Alternatively, in a case that the current base station is the anchor base station of the inactive UE or a previous anchor base station, the paging assistance information may be ignored, and the PEI is sent first and then the inactive UE is paged based on a PEI configuration of the inactive UE.
The PEI may be:
The first class of PEI may be a common PEI, and the second class of PEI may be a PEI specific to a paging packet.
Referring to
At block S310, historical camping information of an inactive user equipment (UE) transmitted by a base station is received.
The core network device may be any device included in a core network, and for example, the core network device can be an AMF.
In embodiments of the present disclosure, the core network device may receive the historical camping information transmitted by the inactive UE from the base station.
Therefore, when the core network device is required to page the inactive UE, the core network device may determine paging assistance information to accurately page the inactive UE, which may reduce unnecessary signaling overhead during paging the inactive UE and/or a power consumption overhead of alarming other inactive UEs.
In some embodiments, the historical camping information includes:
For example, the historical camping cell information at least indicates: the last one or more cells in which the inactive UE camps.
For example, the historical camping base station information at least indicates last one or more base stations in which the inactive UE camps.
The historical camping cell information may indicate one or more cells in which the inactive UE has camped prior to a current time point. For example, the historical camping cell information at least indicates a last cell in which the inactive UE camps.
For example, the historical camping cell information may include: a list of cells. The list of cells contains one or more cell identifications (IDs). The cell identification may be a physical cell identification (PCI).
In response to the historical camping cell information including a plurality of cell identifications (IDs), the plurality of cell IDs may indicate a plurality of cells in which the UE has recently camped.
In an embodiment, the historical camping cell information may further include historical camping length of time information of the UE in the corresponding cell.
In another embodiment, the historical camping base station information may further include historical camping length of time information of the UE at the corresponding base station.
The historical camping length of time information is indicative of both a length of time for once camping or an average length of time for a plurality of camping, etc.
The historical camping base station information is indicative of one or more base stations that the inactive UE has camped prior to the current time point.
The historical camping base station information may include a base station identification.
For example, the historical camping base station information may at least include a base station identification of a last base station in which the inactive UE camps.
In response to the historical camping base station information including base station identifications of a plurality of base stations, the historical camping base station information includes the base station identifications of the plurality of base stations where a plurality of the inactive UEs have recently camped.
In short, the historical camping cell information is at least indicates the last one or more cells in which the inactive UE camps, and/or, the historical camping base station information at least indicates last one or more base stations in which the inactive UE camps.
In an embodiment, the historical camping information may further indicate a historical coverage enhancement level of the UE.
For example, this historical coverage enhancement level may include, but is not limited to, an enhancement coverage level used by the UE at last one or more cells in which the UE camps.
For example, the historical coverage enhancement level may at least include a downlink enhancement coverage level and/or an uplink enhancement coverage level used by the UE when releasing a connection prior to entering into an inactive state.
In some embodiments, the block S310 may include:
In an embodiment of the present disclosure, the historical camping information is included in the RRC inactive state conversion report and reported to the core network device. Certainly, the core network device may receive the historical camping information from other message signaling, for example, receive the historical camping information from a dedicated message in the historical camping information of the inactive UE.
The historical camping information is carried in the RRC inactive transition report, thus, on one hand, there is no necessary to add an additional message signaling to transmit the historical camping information between the base station and the core network device, and on the other hand, the RRC inactive transition report is a report for the base station to notify the core network device that the UE enters into and exits from the inactive state, whereas the historical camping information of the inactive UE is used after the UE enters into the inactive state. Therefore, the RRC inactive transition report carries the history camping information, having a characteristic of strong information relevance and also reducing unnecessary reporting of the history camping information.
In some embodiments, the RRC inactive transition report includes a state value.
A RRC inactive transition report with the state value indicating that the UE is in an inactive state includes the historical camping information of the inactive UE.
The RRC inactive transition report includes one state value which may indicate that the UE enters into the inactive state or may indicate that the UE exits from the inactive state. Since the historical camping information of the inactive UE may be used when the UE is in the inactive state, in order to reduce unnecessary signaling overhead, the RRC inactive transition report carries the historical camping information only when the state value indicates that the UE is in the inactive state. That is, the RRC inactive transition report does not carry the historical camping information of the inactive UE when the state value indicates that the UE exits from the inactive state.
In some embodiments, referring to
At block S300, a request for the RRC inactive transition report is transmitted to the base station.
The RRC inactive transition report is reported based on the request transmitted by the core network device. Certainly, in other embodiments, the RRC inactive transition report may be reported by the base station itself.
For example, transmitting the request for the RRC inactive transition report to the base station includes:
In some embodiments, the core network device simply obtains the historical camping station information when the UE is in the inactive state, then a flag bit may be set in the request. As such, the base station, after receiving the request, transmits to the core network device the RRC inactive transition report including the historical camping station information of the UE, regardless of whether the UE is in the inactive state or not, and in the report, an indication is given as to whether or not the UE is currently in the inactive state.
In some embodiments, the request includes:
In response to the RRC inactive transition report is for the single state reporting request, the RRC inactive transition report carries the historical camping information, or, in case of the issue being in the inactive state, the RRC inactive transition report necessarily carries the historical camping information.
In response to the RRC inactive transition report is transmitted based on the subsequent state reporting request, the RRC inactive transition report possibly carries the history-resident information of the inactive UE when the RRC inactive transition report is a first report based on the subsequent state reporting request, or, the RRC inactive transition report does not carry the historical camping information in case of the RRC inactive transition report being not the first report, thus reducing unnecessary signaling overhead.
In an embodiment, the method further comprises:
In some embodiments, the block S310 may include:
The historical camping information may further be reported to the core network device after a base station is switched from a non-anchor base station of the inactive UE to an anchor base station.
Referring to
At block S410, paging assistance information for paging the inactive UE is determined based on the historical camping information. The paging assistance information is used for paging the inactive UE.
The historical camping information may be received from a base station or determined by other manners. This embodiment may be performed independently or in combination with the method for processing information including the block S310.
For example, the paging assistance information includes:
For example, the paging range, indicated in this first indication information, may be smaller than a radio notification area (RNA) of an access network in which the current inactive UE is located, thus reducing transmission of unnecessary paging messages and reducing paging overhead.
The second indication message may indicate that the paging message is not transmitted according to the PEI after the inactive UE performs the cell reselection, thus reducing a false alarm of the PEI for other inactive UEs that are in a same paging packet as the inactive UE, and reducing a power consumption generated by alarming other inactive UEs.
In another embodiment, in a case that the inactive UE belongs to a specific paging packet, after the packet performs the cell reselection, it is indicated to transmit the PEI before transmitting a paging message for paging the inactive UE. Alternatively, in a case that the current base station is the anchor base station of the inactive UE or a previous anchor base station, the paging assistance information may be ignored, and the PEI is sent first and then the inactive UE is paged based on a PEI configuration of the inactive UE.
The paging packet of the UE may be determined using the following functional relationship:
A packet identification (ID) of the paging packet of the UE is obtained in accordance with a UE-ID mode-taking method, which is given by a following formula:
The UE-ID mode-taking method is a random selection method or a randomization method. All the paging packet resources are modeled according to the UE-ID.
Upon receiving the third indication information, the base station may determine the enhancement coverage level utilized for paging the inactive UE based on the enhancement coverage level, and/or, may determine paging subframes and/or paging carriers, etc., for paging the inactive UE based on enhancement coverage levels configured for respective paging subframes and paging carriers, thus reducing unnecessary paging on other subframes and/or carriers.
A method for processing information is provided in an embodiment of the present disclosure. The method is performed by a base station, and includes a following block.
At block S510, paging assistance information is transmitted to the base station. The paging assistance information is configured to assist the base station in accurately paging the inactive UE.
For example, the paging assistance information may be determined based on historical camping information of the UE. The paging assistance information may include the aforementioned first indication information and/or the second indication information and/or the third indication information.
For example, when the core network device has lost context of the UE and is required to page the inactive UE, the core network device transmits a paging signaling to the base station. The paging signaling may include the paging assistance information.
Simultaneously, the paging signaling is also configured to indicate the base station to broadcast the paging message for paging the inactive UE. For example, the base station pages the inactive UE based on the paging assistance information to reduce transmission of unnecessary paging messages, and save signaling overhead, and/or determining, based on the paging assistance information whether to first send the PEI before paging the UE according to PEI configuration of the inactive UE or to directly transmit the paging message on a PO listened by the UE based on a paging configuration of the UE, to reduce fault alarm of an inactive UE in the same paging packet as the UE.
After receiving the third indication information, the base station may determine, based on the enhancement coverage level, paging parameters such as the enhancement coverage level, the paging subframes and/or the paging carriers for paging the inactive UE, thus reducing unnecessary paging on other subframes and/or carriers and increasing a success rate of paging of the inactive UE.
The historical camping information added between the base station and the core network may be used to determination of carrying the paging assistance information of the core network for the inactive UE. The paging assistance information may be used for paging the inactive UE.
The historical camping information includes one of:
As an embodiment, information content interacted between the base station and the core network may further include a coverage enhancement level.
Correspondingly, the paging assistance information may further include indicating a coverage enhancement level of the inactive UE.
The history camping information is carried in the RRC inactive transition report transmitted to the core network.
The history camping information is optionally carried in a RRC inactive transition report message transmitted to the core network.
The historical camping information needs to be carried only when a value of a state value (RRC State) in the RRC inactive transition report indicates that the UE is in the inactive state.
The historical camping information needs to be carried only when a value of a state value (RRC State) in the RRC inactive transition report indicates that the UE is in the inactive state and following cases are fulfilled.
The base station receives a RRC inactive transition report request, a type of which is single state reporting “single RRC connected state report”.
The base station receives a RRC inactive transition report request, a type of which is subsequent state reporting “subsequent state transition report”. Then, the base station needs to report the historical camping base station information only once.
For example, when the core network device is informed for the first time that the UE is currently in the inactive state, the historical camping information is carried in the RRC inactive transition report.
The historical camping information may be carried in a path transformation request message transmitted to the core network.
As an embodiment, the non-anchor base station may notify the core network of the historical camping information after converted to a new anchor base station.
For example, a protocol agrees that the path transformation request message or the RRC inactive transition report carries the historical camping information of the UE. The historical camping information at least indicates the cell and/or the base station where the UE currently camps.
Embodiments of the present disclosure provide a technical solution, in which the base station transmits the historical camping information of the inactive UE to the core network device, so that the core network device will know the historical camping information of the inactive UE, which facilitates the core network device in determining suitable current paging assistance information based on the historical camping information of the inactive UE, to realize precise paging of the inactive UE and/or improving a paging success rate.
