UT switching

At some time point, UT may need to be switched to another satellite (being not shown in Fig. 1).Switching may be by adjusting Caused by degree event or non-scheduled event.

Here is several examples of the switching as caused by scheduling events.Between wave beam and inter-satellite switching may be by satellite Movement, UT movement or satellite beams close caused by (for example, as geostationary satellite (GEO) limitation cause).Switching Be also likely to be due to satellite remove GN range and satellite still in the sight of UT caused by.

Here is several examples of the switching as caused by non-scheduled event.Switching may be by satellite by barrier (example Such as, set) it blocks to trigger.As rain decline or other atmospheric conditions caused by channel quality (for example, signal quality) decline, It may triggering switching.

In some implementations, in particular point in time, particular satellite can be by the special entity in GN (for example, network insertion Controller (NAC)) it controls.Therefore, GN can have several NAC (for example, being realized by the GN controller 250 of Fig. 2), each NAC controls the corresponding satellite in the satellite controlled by GN.In addition, given satellite can support multiple wave beams.Therefore, with when Between passage, it may occur however that different types of switching.

Between wave beam in switching, UT is from a beam switchover of satellite to another wave beam of the satellite.For example, with clothes Being engaged in, satellite is mobile, and the particular beam for static UT service can change over time.

In inter-satellite switching, UT is to be switched to another satellite from current service satellite (referred to as source satellite) (to be claimed For target satellite).For example, UT can be switched to mesh as source satellite moves away from UT and when target satellite is mobile towards UT Mark satellite.

Idle mode switching

In satellite network, the UT in idle mode should be directed toward best satellite and wave beam to receive and be directed to free time UT's Paging.Similarly, GN should page idle UT using identical satellite beams.In fact, to correct satellite and wave beam Possible challenging (for example, relative complex) is selected, this is because satellite and wave beam may be as known to GN but for sky Not busy UT is not known a variety of causes and is closed.Therefore, idle UT, which may be directed toward, is used to page the satellite of idle UT not with GN Same satellite, this is possible.

In order to solve this problem, in certain aspects, this disclosure relates to the idle modes of netboot to switch Journey enables idle UT to reliably receive the paging message sent by GN.In order to receive paging, idle UT identification will be at that When provide the satellite of covering for idle UT and its antenna be directed toward the satellite.This make idle UT then can be tuned to satellite By in the wave beam wherein sent, reside in corresponding cell, and monitoring control channel is directed to determining whether there is The paging of idle UT.

In certain aspects, the idle mode handoff algorithms of netboot are related to: when UT is in idle mode, GN is repeated Ground (for example, periodically or aperiodically) provides the UT letter that can be used for executing switching (gravity treatment) to idle UT on demand Breath.The information can be referred to as idle mode information.UT can be by the information preservation in idle mode switching table.

Idle mode information can use various forms.In some cases, idle mode information instruction will be at one section It is interior covering free time UT a series of satellites so that free time UT can then be directed toward correct satellite and receive paging (for example, At the appointed time locate).In some cases, idle mode information includes at the beginning of satellite set, wherein Mei Gete Determine when instruction time started, UT free time can be switched to corresponding satellite.Therefore, in certain aspects, this application involves networks to draw The idle gravity treatment led, wherein UT is by netboot to the satellite list appropriate for being used for idle mode operations.

In some scenes, idle UT requests idle mode handover information from GN.In some scenes, when idle UT has In idle mode switching table when the remaining valid entry for defining quantity, idle UT can send to GN and cut for idle mode Change the request of information.For example, idle UT can send request when an only remaining undue entry in table.Some In scene, if idle mode switching table will expire or expire, free time UT can be sent to GN for idle mould The request of formula handover information.In some scenes, idle UT can based on idle mode switching table particular items (for example, Last entry) associated time, the request for being directed to idle mode handover information is sent to GN.

At the beginning of request may include the last entry in the current idle pattern switching table for example at UT With the position of UT.The information, which can determine GN, to cover next satellite set of free time UT, and determine when to send out to UT Send the instruction to next satellite set.

In some scenes, GN can send idle mode information to UT during radio connection operates.For example, when sky When not busy UT establishes the radio connection with GN, idle UT can send the request for being directed to idle mode handover information to GN.As Another example, when idle UT establishes the radio connection with GN, GN can be automatically (for example, come from free time UT no Request in the case where) to idle UT send idle mode handover information.

Example hand off signaling

In certain aspects, this disclosure relates to the signalings for supporting idle mode to switch.Fig. 6 is shown including The communication system 600 of one device 602 and second device 604.The maintenance of first device 602 (for example, generation) idle mode switching letter Cease (for example, table) 606, and the transmitter 608 including idle mode handover information 610 can be sent to second device 604.The Two devices 604 include receiver 612, are used to receive idle mode handover information 610, second device 604 is saved Local idle mode handover information 614.In certain aspects, first device 602 can be the example of the GN 200 or GN 201 of Fig. 1 Son.In addition, second device 604 can be the example of the UT 400 or UT 401 of Fig. 1.

In some implementations, communication system 600 is satellite communication system.Fig. 7 is shown in native to this world synchronous satellite communication UT 702 is via satellite in system 700 (for example, being used for data, voice, video or the LEO satellite communication system of other communications) 706 communicate with GN 704.UT 702, GN 704 and satellite 706 can respectively with the UT 401 of such as Fig. 1, GN 200 and defend Star 300 is corresponding.

GN 704 include each of network access controller (NAC) 712, NAC 712 with for via satellite 706 One or more radio frequencies (RF) that (or some other satellite, be not shown) are communicated with UT 702 and other UT (not shown) System 714 is docked.GN 704 further includes core network control plane (CNCP) for being communicated with another network 720 716 and core network user plane (CNUP) 718 or other similar functions.Network 720 can indicate in such as the following terms It is one or more: core network (for example, 3G, 4G, 5G etc.), Intranet or internet.

In various time points, GN 704 can determine (for example, receive or generate) idle mode handover information 722.GN is right Afterwards can via the message 724 and 726 relayed from satellite 706 to UT 702 broadcast or unicast idle mode handover information 722.By This, UT 702 saves the idle mode handover information 728 of their own.GN 704 can in response to the request from UT or automatically (for example, being not responsive to request) sends idle mode handover information 722 to UT.

In example implementation, the request for idle mode switching table may include two fields.First field includes working as At the beginning of the last line entry of preceding table (for example, absolute GPS time).If UT does not have current table, can will start Time is set as 0.First field can be 32 bits or some other size.Second field include UT with last received table Corresponding position (for example, the field can be only used for mobile UT).The field can be 32 bits or some other size.? In some realizations, request can also include (for example, in another field) having to the current idle pattern switching table at UT The instruction of effect property time (for example, about the table, there are also how long be effectively to indicate).

In certain aspects, this disclosure relates to use to idle mode handover information (for example, idle mode switches Table) the transmission based on unicast signaling.In certain aspects, compared with being updated based on the idle mode of broadcast message block, unicast Signaling can provide more flexibilities (for example, unicast signaling can be more suitable for following development).

Fig. 8 shows the example of the signaling call process 800 for providing handover information (for example, switching table) to idle UT Son.Signaling call process 800 includes request-response radio message pair, can be based on the idle mode of such as netboot Handoff algorithms.

It in certain aspects, can be in UT when UT is radio connection, and when safety is movable 806 Request-response message pair is exchanged between 802 and GN 804.That is, radio requests-response message can be used for radio connection UT idle mode switching table is provided, and the table can be and provide after safety is activated.

Idle mode switching table request message 808 can be sent after sending UT location information (or can send out It send when UT location information while sending idle mode switching table request message 808).For example, request message 808 can be with wirelessly What the electric position UT report message 810 provided simultaneously.

In certain aspects, GN can be used UT location information to prepare idle mode switching table for UT.For example, GN can be with Position based on satellite ephemeris information and UT, to determine which satellite interior at a given time period can service for UT.Then GN sends the idle mode switching table response message 812 including the satellite information to UT, and UT updates its table 814.

In some implementations, GN can be determined whether based on the validity time of the current idle pattern switching table at UT Idle mode switching table is sent to UT.In some cases, GN can be received from UT to the instruction of the validity time (for example, In idle mode switching table request message).In some cases, GN oneself can track the validity time (for example, being based on The validity time that GN is calculated for GN the last one meter for being sent to UT).

In some implementations, GN can based on the current idle pattern switching table at UT entry (for example, the last one Entry) associated time (for example, time started), to determine whether that UT sends idle mode switching table.In some cases Under, GN can receive the instruction (for example, in switching table request message) to the time from UT.In some cases, GN can be with Oneself track the time (for example, the last one table for being sent to UT by saving GN).

In view of the foregoing, in certain aspects, this disclosure relates to send to UT to the idle mode behaviour for UT The instruction at least one satellite made.It herein, can be using satellite table, the form of satellite list to the instruction of at least one satellite Or some other form.For each satellite in (for example, in satellite list) at least one satellite, can also be sent out to UT Send the instruction for being used to indicate time of the UT by the satellite is switched to.It can also be sent to UT to next satellite cell (for example, will For the cell of the next satellite of UT service) by the instruction of at least one carrier frequency sent at which.

In certain aspects, it can be based on for sending the decision of instruction: 1) position of UT；2) current idle pattern switches At the beginning of entry (for example, last entry) in table；3) quantity of the valid entry in idle mode switching table；Or 4) a combination thereof.In certain aspects, the last one idle mode that can be provided based on GN to UT for sending the decision of instruction The validity time of switching table.Above- mentioned information make GN can determine whether UT will be finished present satellites information.Therefore, if The last one table for being sent to UT will be finished valid entry or the table i.e. will be expired, then GN can send new table to UT.

Example switching table

GN can send idle mode handover information (for example, automatically or in response to asking via idle mode switching table It asks).Example free time pattern switching table is shown in table 1.The basic time (for example, in seconds) of the table can be for example absolutely To GPS time (for example, 32 bits).The table will be updated (for example, as satellite is mobile and/or UT over time It is mobile).It should be appreciated that different switching tables may include different types of information and/or different entries.

Satellite ID	Time started (for example, second)
		Sat1	startTime1
It interrupts	startTime2
		Sat3	startTime3
…	…
		SatN	startTimeN

Table 1

In example implementation, switching table may include next three fields.First field for the table it is basic when Between (for example, in seconds): the absolute GPS time (for example, 32 bits).Second field is used for satellite ID (for example, 16 bits). Table 1 shows the example of the field.As shown, the second field also can indicate that when no satellite cover UT (for example, due to EPFD alleviate) when the interruption period.Third field is used for the time started: startTime1 ..., startTimeN is (for example, every A 32 bit).Table 1 also shows the example of the field.It can choose these times, so that GN can specify relative in its phase Between table clause be the sufficiently long period for effective basic time.

It is static or mobile that the size for being provided to the switching table of UT, which can depend on UT,.In general, lesser cut Changing table can be used for mobile UT, and thus the size of this switching table can depend on speed used by UT is being moved.

For the UT (for example, UT on aircraft) fast moved, lesser table can be provided, this is because since UT is transported It is dynamic, so that the table may be rapidly invalid.Such table may be effective within such as a few minutes.

For the UT (for example, UT on pleasure boat or container ship) slowly moved, biggish table can be provided.Such table It can be effective in such as one hour.

For static UT, big table can be provided to reduce by establishing new connection (for example, as begged in following option 1 Opinion) or due to expense caused by signaling overheads (for example, as discussed in following option 3).Such table may It is effective within such as a few houres (for example, 10 hours).

GN can estimate the speed of UT based on GN from the received position report of UT.The information is connect in request message Receiving is that the information of effective time is combined in it about current table UT at, and GN can optimize GN to mobile UT offer Table size.This can help to realize in transmission table caused signaling overheads and provided table in it for mobile UT For keep good compromise between the effective period.

In different situations, may exist for different reasons and interrupt the period.For example, one or more satellites can It can be inactive (for example, UT originally will be during the period in the covering of satellite), and therefore service can not be provided. As another example, service limitation (for example, supervision limitation or country's limitation) may indicate that UT can not be received from particular satellite Service (for example, service is restricted always, at certain times or at certain positions).

In certain aspects, low-power (for example, sleep) mould can be held in for determining by UT by interrupting period information Formula still enters the mode.For example, being in or can determine that it can be from based on table 1 into the UT of idle mode StartTime2 sleeps to startTime3.

For requesting or sending the triggering of idle mode handover information

Various types of triggerings can be used to determine when to request or send idle mode handover information (for example, idle Pattern switching table).Here is that UT (or some other types of equipment) can be used to determine when request idle mode switching letter Breath or GN (or some other types of equipment) are if can be used to determine when the triggering of transmission idle mode handover information Dry example.

First request triggering is based on the idle mode handover information set safeguarded by UT (or some other suitable equipment) The quantity of remaining valid entry in (for example, idle mode switching table).For example, UT can be based in the idle mould safeguarded by UT The quantity (for example, one, two etc.) of remaining valid entry is sent for idle mode handover information in formula switching table Request.As specific examples, if idle mode switching table only includes a valid entry (or two valid entries or three Valid entry etc.), then UT can send the request for being directed to idle mode handover information to GN.In this way, UT can be Before being finished effectively (for example, current) entry by the idle mode switching table that UT is safeguarded, new idle mode switching is obtained from GN Table.In certain aspects, if the time associated with the entry in table (for example, time started, end time etc.) has been subjected to It goes, then the entry is considered invalid (for example, not being current).

Second request triggering is based on the idle mode handover information set safeguarded by UT (or some other suitable equipment) The timing of the entry of (for example, idle mode switching table).For example, UT can based on the idle mode switching table safeguarded by UT Particular items (for example, last entry, penultimate entry etc.) associated timing (for example, the time started, at the end of Between etc.), to send the request for idle mode handover information.As specific example, if current time is cut with idle mode When the difference changed between the time (for example, time started etc.) of the particular items in table (for example, last entry) is less than thresholding The area of a room, then UT can send the request for being directed to idle mode handover information to GN.In this way, UT can safeguarded by UT Before (for example, before the table is finished entry or the table is no longer valid) idle mode switching table is finished current entries, from GN Obtain new idle mode switching table.

Combination of the third request triggering based on the first request triggering and the second request triggering.For example, if idle mode is cut Changing table only includes a valid entry, or if when the difference between current time and the time of last entry is less than thresholding The area of a room, then UT can send the request for being directed to idle mode handover information to GN.Other combinations can be in other scenes.

In some scenes, GN (or some other suitable equipment) can track table (or some other equipment of UT Table), to determine when to send idle mode handover information (for example, idle mode switching table).For example, such case may occur In the case where UT (or certain its other equipment) does not send the request for new table.

First sends triggering based on the idle mode handover information (example for being sent to UT (or some other suitable equipment) Such as, idle mode switching table) will keep effectively up to how long.For example, GN (or some other suitable equipment) can be based on The remaining validity period of the idle mode switching table of UT to send idle mode handover information to UT.As specific example, such as The remaining validity period that fruit GN is sent to the last idle mode switching table of UT is less than threshold amount of time, then GN can be sent out to UT Send new idle mode switching table.In this way, GN can before the idle mode switching table that UT is safeguarded becomes invalid, New idle mode switching table is provided to UT.

Other triggerings for sending idle mode handover information can be similar to the first request triggering, the second request triggering It requests to trigger with third.For example, GN can be based on UT based on the quantity of remaining valid entry in the idle mode switching table of UT Idle mode switching table in particular items (for example, last entry) time (for example, time started), or be based on The combination of these triggerings, to send idle mode handover information.

Example message

GN (or some other suitable equipment) can send various types of to idle UT (or some other suitable equipment) The information of type.In some scenes, the information can be sent via broadcast message block (BIB) message.It, should in example implementation Information indicates that next cell will be at least one carrier frequency (for example, absolute RF channel number) wherein sent.It should Information can be carried by 16 bits (or the other sizes) parameter for being referred to as " nextCellTransmitFreq ".As an example Son, nextCellTransmitFreq can indicate the list for the possibility frequency that can be followed.As another example, NextCellTransmitFreq can indicate specific frequency.It should be appreciated that nextCellTransmitFreq can also be with It takes other form.It assume that satellite by forward direction service link (FSL) on given area, uses limited quantity (N) The carrier frequency of (for example, 8 or some other suitable quantity) is sent.The set of N number of carrier frequency can be due to area It is different.

UT can execute it is following operation be tuned to satellite wave beam.When UT according to idle mode switching table from a satellite When being transposed to another satellite, UT can be executed in N number of frequency to be searched for and selects a frequency to be resident.When UT is from satellite Wave beam when being transposed to another wave beam of the satellite, nextCellTransmitFreq information can be used in UT.For example, When UT is just covered by satellite, UT nextCellTransmitFreq information can be used determine UT should be tuned under it One wave beam.

Example signaling

Here is several examples based on signaling above and UT process.These examples are referred to as option 1, option 2, option 3 and option 4.

In option 1, when there is idle UT an entry to stay in its current table, which sends request message to GN. Herein, UT is established to the radio connection of GN and is sent request message.UT radio layer can trigger control layer to initiate to take Be engaged in request process and establish to GN radio connection.When receiving request message, it includes new switching table that GN is sent to UT Response.UT replaces its current table with new table when receiving response message.

In option 2, UT does not send request message.It is provided most about GN to the UT on the contrary, GN is safeguarded for each UT The information of the validity time of the latter table.Whenever UT is established to when the radio connection of network, GN is checked the need for UT New table is provided and sends new table when needed.In some cases, the radio of the position of instruction UT is received from UT in GN After the report message of position, GN can send new table.

In option 3, each UT is established to when the radio connection of GN, and UT just sends request message to GN.Based on request The information provided in message, GN are determined the need for UT offer table.For example, if static UT has into enough time in future Entry, then do not need to provide new table to the UT.For mobile UT, GN can be come based on the information provided in request message Optimize its size (for example, as discussed about the table size for static and mobile UT) to the UT table provided.Once UT Response message is received from GN, UT can replace the entry of overlapping and new entry is attached to its current table.

Option 2 allows the process to be mounted in by UT for various reasons (for example, when UT has the uplink to be sent When road (UL) data, perhaps when UT responds paging or when periodical timer (for example, 54 minutes period) arrives When the phase) establish radio connection on.Therefore, in these scenes, it may not be necessary to establish additional connection to send request Or receive idle mode switching table.In some implementations, timer can be paging domain update timer.It can be in other realities Other types of timer is used in existing.

Option 4 is the combination of option 1 and option 3.For example, UT can establish whenever ending of the UT close to its current table Radio connection is to obtain new table.In addition, UT can required list whenever establishing radio connection for other reasons.Under Face is the example of option 4.

When idle UT has found that there is an entry to stay in its current table for it, UT radio unit triggers control layer to send out It plays service request procedure and establishes to the radio connection of GN.Then UT sends switching request, and conduct on which Response, GN provide new table to UT.Then, UT replaces its current table with new table.

As discussed above, static UT and mobile UT may have different constraints.Static UT can benefit from big table (10 Hour is longer), to reduce connection expense.Lesser table can be used in mobile UT because significant movement may make table without Effect.Therefore, handover information amount transmitted by GN can the movement (for example, speed) based on UT.

As discussed above, whenever UT by radio connection to GN when, UT can send switching table request message.It is receiving When to the message, GN determines whether should be to UT offer table.If the current table of static UT has into enough time in future Entry does not need then to provide new table to the UT.For mobile UT, GN can provide the table with smaller size.UT can connect (for example, replacement overlapping entry) additional when response message is received to its switching table.

Example timeline

Fig. 9 is shown (to be specified when free time UT is transposed to the second satellite from the first satellite (being appointed as SAT1) according to switching table Example timeline 900 when for SAT2) at free time UT.The example is used for the UT with dual paraboloid antenna.In example implementation, Indicate the worst case time 902 for completing to rotate and be directed toward SAT2 about UT antenna (for example, antenna 2).In exemplary scene In, the elevation coverage that such antenna may spend be rotated by 90 ° for about 5 seconds is (for example, the minimum at particular azimuth is faced upward Angle sweep speed can be 18 degrees seconds).

At the time 904, the antenna (antenna 2) of UT starts to rotate and is directed toward SAT2.At the time 906, UT reading is worked as BIB in preceding cell with find want be tuned to next cell.At paging occasion (PO) 908, UT uses another antenna (for example, antenna 1) monitors the control channel in subframe, to determine whether there is the paging for being directed to UT 910.Start in SAT2 At time 912, the antenna 2 of UT is directed toward the second satellite SAT2.At the time 914, UT is measured in the next cell to be resident FSL frequency.For example, UT can measure up to 120 milliseconds or reach some other time section.At the time 916, UT read and Handle BIB1.For example, UT, which can execute these, operates up to 85 milliseconds or reaches some other time section.During PO 918, UT ginseng With paging.In example implementation, paging circulation 920 is 1280 milliseconds.

Additional handover operation

Referring to Fig.1 0, the various aspects of present disclosure are related in satellite communication system 1000 via satellite 1006 and GN The switching of 1004 UT 1002 communicated.In some implementations, system 1000 can be native to this world synchronous satellite communications system, Such as data, low earth orbit (LEO) satellite communication system of voice, video or its communication.UT 1002 is the UT of Fig. 1 The example of 400 or UT 401.GN 1004 is the example of the GN 200 or GN 201 of Fig. 1.Satellite 1006 is the satellite 300 of Fig. 1 Example.

In certain aspects, GN 1004 and UT 1002 are determined when using satellite and cell switch information 1008 by UT 1002 are switched to another cell from a cell and/or are switched to another satellite from a satellite.For example, UT 1002 can To send UT information 1010 (for example, ability information, location information or other information) to GN 1004 via the first signaling 1012. Based on information 1010, GN1004 or some other entity generate satellite and cell switch information 1008, and via the second signaling 1014 send information 1008 to UT 1002.Alternatively or additionally, GN 1004 or some other entity are selected based on information 1010 Select the handoff procedure for UT 1002.In certain aspects, UT 1002 different satellites (new demand servicing satellite) are switched to be related to UT 1002 carries out satellite-signal measurement and sends measurement message 1016 to GN 1004.In certain aspects, as receiving Measurement message 1016 as a result, GN 1004 generates new satellite and cell switch information (for example, modification satellite and cell switch Table).

UT 1002 can execute other switching relevant operations according to the teaching of this article.In certain aspects, 1002 UT Satellite ephemeris information can be received via GN 1004, and be synchronized to satellite (for example, satellite using satellite ephemeris information 1006).In certain aspects, if UT 1002 loses the connection to satellite and/or cell, UT 1002 calls Radio Link Failure Mode.

In certain aspects, switched design can be attempted to meet one or more design objects.The example packet of this target It includes: during switching signaling being minimized；Make data outage minimized during switching；Or it reduces to UT to Satellite Count the dependence (for example, alternatively, knowing dependent on GN satellite position and the position UT) of evidence known one by one.

In the example of Figure 10, GN 1004 includes each of network access controller (NAC) 1018, NAC 1018 With for being communicated with UT 1002 and other UT (not shown) via satellite 1006 (or some other satellite, be not shown) One or more radio frequency (RF) subsystems 1020 dock.GN 1004 further includes the core net for being communicated with network 1026 Network controls plane (CNCP) 1022 and core network user plane (CNUP) 1024 or other similar functions (for example, for other The network-based control and user-plane function of type).Network 1026 can indicate such as one or more of the following items: core Heart network (for example, 3G, 4G, 5G etc.), Intranet or internet.

In some implementations, GN 1004 determines (for example, receive or generate) satellite and cell switch information 1008.For example, NAC 1018 can be based on via 1026 received information (for example, ephemeris information) of network and from the received information of UT (for example, matching Confidence breath and measurement message), generate the satellite and cell switch information for all UT under the control of NAC 1018.Make For another example, NAC 1018 can receive the satellite for being directed to its UT via network 1026 (for example, from network entity 1028) With cell switch information.

Satellite and cell switch information 1008 also can be generated in other entities in the system.In some implementations, network Satellite and cell switch information 1008 can be generated in the controller 1030 of entity 1028, and sends out to the control assembly of system 1000 Send satellite and cell switch information 1008 (for example, between system startup and/or at other times locate).For example, network entity 1028 can be via network 1026 (for example, core network, Intranet or internet) or some other data transfer mechanism, to GN 1004 send satellite and cell switch information 1008.For purposes of illustration, network entity 1028 is depicted in network 1026 Except.However, network entity 1028 can be a part of network 1026.

UT, the GN that can be used in combination with the switching of UT according to the teaching of this article will now be described or the several of satellite show Example aspect.For the component given in these satellite system components, these aspects may include one or more in the following terms : parameter used in the component or other information, the parameter for being assigned to the component, the characteristic of the component (for example, ability), Signaling used in the component or the operation executed by the component.

Satellite ID

Satellite identifier (ID) is unique ID of the particular satellite in satellite system.Satellite ID allows in satellite system (for example, by UT) uniquely identifies the satellite.In order to allow Large-scale satellite to dispose, satellite ID can be 16 bits or more ratio It is special.In some implementations, satellite ID is to send on overhead channel, and do not need to be read immediately by UT.UT and GN can be with Ephemeris information table is indexed using satellite ID, with the cell of position location satellite and the satellite in the earth at given time On projection.

Cell or wave beam ID

Cell ID is unique ID of cell.Similarly, wave beam ID is unique ID of wave beam.For convenience's sake, term is small Area/wave beam can be used to indicate cell and/or wave beam herein.Cell/wave beam ID allows cell/wave from given satellite Beam (for example, by UT) uniquely identifies.In certain aspects, cell/wave beam ID can be by UT within the very short period Detect (for example, cell/wave beam ID can be the continuous signature used in cell/wave beam pilot tone).Therefore, UT may not Need to decode Overhead Message to find cell/wave beam ID.In a non-limitative example, cell/wave beam ID may include 10 Bit: 2 bits for GN ID are (for example, 2 bits can be enough with the visible unique GN of UT；And it is used for 4 of GN ID Value can reuse in the world)；And 8 bit of cell/wave beam for GN order is (for example, GN controls about 10 16 wave beams of satellite x/satellite=160 wave beam/GN=> 8 bit is to uniquely identify cell/wave beam).In other realizations In, the bit of different number can be used.Furthermore, it is possible to take into account the space diversity of satellite to reduce amount of bits.

UT ability

UT can exchange its ability with GN in connection or at some other time.Here is the several unrestricted of UT ability Property example.

UT can have double small area/wave beam sensing function.Therefore, a UT ability parameter is (for example, its value is YES (YES) or NO (no)) it can indicate whether UT can sense more than one cell/wave beam.For example, when UT uses particular satellite When cell/wave beam is actively communicated, which can indicate whether UT can sense and detect same satellite Another cell/wave beam cell/wave beam ID.In some implementations, which can serve to indicate that whether UT can be same When support two cell/wave beams.In other implementations, can support different number cell/wave beam (for example, three or more It is a).

UT can have double satellite sensing functions.Therefore, another UT ability parameter (for example, its value be YES (YES) or NO (no)) it can indicate whether UT can sense more than one satellite.For example, when UT is living using cell/wave beam of particular satellite When being communicated dynamicly, which can indicate whether UT can sense and detect cell/wave beam of another satellite ID.In some implementations, which can serve to indicate that whether UT can support two satellites simultaneously.In other realizations In, it can support the satellite (for example, three or more) of different number.

As discussed in more detail below, the sensing function of UT can be used to determine the switching type of UT to be used in GN.Example Such as, if UT once can only support single subdistrict/wave beam, switching can be based simply on satellite and cell switch table.Phase Instead, if UT can once support multiple cell/wave beam/satellites, GN that can disappear during switching for the measurement from UT Breath is monitored, thus measure message can influence how (for example, when and/or where) switching UT.

Another UT ability parameter can be with indicator between tuning period (example the minizone tuning period and/or wave beam of UT Such as, with microsecond (μ sec) for unit).For convenience's sake, tuning period can be used for referring to minizone between term cell/wave beam Tuning period between tuning period and/or wave beam.The UT ability parameter can indicate that UT ceases listening for cell/wave beam and starts to supervise The duration for listening another cell/wave beam of same satellite to be spent.Therefore, in certain aspects, tuned between cell/wave beam Time indicate UT from cell/wave beam be tuned to another cell/wave beam spend how long.

Another UT ability parameter can with indicator to the inter-satellite tuning period of UT (for example, being single with microsecond (μ sec) Position).The UT ability parameter can indicate that UT ceases listening for cell/wave beam on present satellites and begins listening for another satellite Duration for being spent of cell/wave beam.Therefore, in certain aspects, inter-satellite tuning period indicates UT from a satellite Be tuned to another satellite spend how long.

In some implementations, it can be provided tuning period as the upper limit.For example, tuning period can indicate expected UT from The maximum amount that one cell/wave beam or satellite tuner are spent to another cell/wave beam or satellite.

In some implementations, tuning period can be described according to formula.The non-limitative example of this formula is: a+b* τ, wherein a is the constant for indicating the minimum duration of inter-satellite tuning, and τ is the angular distance between present satellites and target satellite From (as unit of degree), and b is the movement speed of UT antenna (as unit of every millisecond of move angle).

Definition is left in tuning

Signaling can be used to allow UT tuning to leave for sensing between inter-satellite and cell/wave beam.The signaling can be with The period is left for the tuning of the UT other cell/wave beams or other satellites for sensing same satellite for defining.

The position UT

The position UT report mechanism is used for hand-off process and paging, so that GN will be appreciated by the position of UT (for example, continuing or determining On the basis of phase).In some implementations, UT will have reliable global positioning system (GPS) positioning.

For static UT, the position UT report mechanism can be related to the position (for example, GPS coordinate) that UT sends report UT to GN Signaling message.

For mobile UT (for example, UT on ship or aircraft), the position UT report mechanism can be related to UT and send report to GN Accuse the speed of UT and the signaling message in direction.This permission GN constantly estimates the position of UT.Even for mobile UT, if UT by Relatively large ship carries (for example, being attached to the ship), then direction and velocity information are also possible to metastable.

In addition, can be notified to UT permitted before needing new location update message via position related signaling Position excursion.

Some realizations can be using the thresholding for position of related features.Some realizations can be protected using GEO.For example, if Beyond the specified boundary (for example, UT is far from some distance) relative to satellite and/or GN, then UT can be configured as sends out UT to GN Send location updating.

Ephemeris transmission and update signaling

Ephemeris transmission and update signaling message can be used for transmitting satellite almanac data to UT.In certain aspects, ephemeris Data include the geographical description about given satellite in given point in time wherein.When UT searches for next satellite and cell/wave When beam (for example, after UT detects Radio Link Failure), which can be used by UT.For example, in certain aspects, UT The almanac data for giving satellite can be used to determine and make UT antenna (mutiple antennas) is directed toward where in given point in time. In certain aspects, GN can send the signaling message comprising satellite almanac data (for example, whenever presence to the UT of all connections When update).In certain aspects, UT can request satellite almanac data (for example, when UT establishes connection) from GN.

Satellite and cell switch table

Each satellite beams can be considered as the individual cell of the data with their own and control channel and signal. Satellite and cell switch table can be generated in GN or some other entity, and providing UT can choose the satellite for being next switched to it List.Conversion table can also accurately indicate UT by when from a cell of next satellite (for example, with wave beam and/or RF frequency band is corresponding) it is transposed to another cell.For multiple satellites, conversion table can indicate the cell that be used for each satellite (for example, wave beam and/or frequency band).For each cell (for example, wave beam), conversion table can indicate the cell frequency (for example, Nominal radiofrequency or frequency band).Conversion table also can indicate that the cell ID (or wave beam ID of each wave beam) of each cell.

GN can define satellite and cell switch table based on various information.In certain aspects, GN can be used UT's Position (and speed and direction, if specified) defines table.In certain aspects, GN can be used according to almanac data The satellite position over time calculated defines the table.In certain aspects, GN can based on about certain cells/ Wave beam and/or satellite whether at certain times pent information defines the table.

Following table 2 is an example of satellite and cell switch table.The entry of the table includes satellite ID, wave beam ID, wave Beam frequency (Freq), starting and end time.The table can also be referred to as satellite and wave beam conversion table.TAbeam indicate from Tuning time departure of one wave beam of the same satellite to another wave beam.In this example embodiment, UT will be from time a1 to time B1 be tuned to satellite 1, wave beam 1 (on frequency F11).Then, UT will from time b1+TAbeam to time c1 be tuned to satellite 1, Wave beam 2 (on frequency F21), and so on.

In some implementations, can at any time before UT is switched to next satellite, from GN to it The table is sent in the signaling message that the UT of service is sent.

Table 2

In one example, the expense of satellite and cell switch table message (is defended as follows assuming that listing two in table Star): satellite ID=16 bit；Wave beam ID=10 bit；Frequency=4 bits (assuming that each satellite has 16 beam frequencies)；With And start and end time=15 bits.

Starting and end time can be specified according to frame number.Physical layer, which can specify, uses 10 millis for system Second (ms) transmission frame.Occurring once assuming that satellite switches every 3 minutes, then the quantity for the frame that can be sent between switching is 18, 000.After each switching, frame number can be reinitialized from zero.Amount of bits required for so specified frame number exists It is therefore 15 bits in the example.

In the above example, the overhead of message will be 1020 bits=128 bytes (approximation).By specified a1, B1 ..., the value of n1, TAbeam.

If place can service most 1000 active users to a wave beam at any time, and if under wave beam totality Line link (DL) handling capacity is about 300Mbps, then expense is given by: expense=(128 bytes × numUsersBeam)/ (total byte that wave beam transmits in 3 minutes)=(128 byte × 1000)/(300 × 106 × 3 × 60)=19 × 10-6 is (close Like).

Following table 3 is another example of satellite and cell switch table.Satellite ID is the satellite being assigned in system Unique ID.Forward link (FL) frequency band is positive integer index, identifies the transmission band of FL.Returning to link (RL) frequency band is just Integer index identifies the transmission band of RL.

Switching activationary time specifies when UT should stop sending and receiving.In some implementations, which is small in source In area with system frame number (SFN) be unit come it is specified.For example, SFN can be, to be assigned to 10ms physical layer transmission wireless The sequence number of frame.UT stops sending and receiving when SFN starts.For example, if switching activationary time is appointed as in SFN 5 Place, then UT stops sending or receiving at the subframe 0 of SFN 5.

Table 3

At switching activationary time is plus tuning time departure, UT starts to be sent or received in Target cell.With Two examples of the relevant UT parameter of tuning time departure are minizone tuning time departure and inter-satellite tuning time departure.This A little parameters can be included in UT ability information.

Inter-satellite switching

Figure 11 and 12 shows the example of inter-satellite switching.In these examples, GN includes the source NAC for controlling the first satellite With the target NAC of the second satellite of control.In each case, UT is initially connected to source satellite (and being therefore connected to source NAC), And it is subsequently handed to target satellite (and being therefore switched to target NAC).In other implementations, different number can be supported NAC and satellite.In addition, in some implementations, public (for example, identical) entity can support multiple satellites.

Figure 11 is the example that wherein UT 1102 does not send measurement message.For example, UT 1102 may not be supported to multiple small The sensing or UT 1102 of area/wave beam and/or satellite, which can determine, not to be needed to send measurement message to GN 1104.This In the case of, UT 1102 and GN 1104 are next small to determine when to be transformed into dependent on existing satellite and cell switch table Area/wave beam and/or satellite and conversion are to where (for example, which cell/wave beam, which frequency, which satellite).UT 1102 It is the example of the UT 400 or UT 401 of Fig. 1.GN 1104 is the example of the GN 200 or GN 201 of Fig. 1.

Source NAC 1106 sends control signaling 1108 to UT 1102.The control signaling 1108 may include such as measurement letter Control information (for example, definition is left in tuning) is left in breath and tuning.In addition, the exchange point between UT 1102 and source NAC 1106 Group data 1110.Source NAC 1106 is the example of the NAC 1012 of Figure 10.

At some time point, triggering switching 1112.For example, current time can with indicated by satellite and cell switch table It is corresponding to the time of the conversion of next satellite from a satellite.

Other handover triggers can also be used.For example, GN 1104 (for example, source NAC 1106) can autonomously decide on UT 1102 need to be switched.This triggering may be as caused by such as the following terms: current service satellite is removing UT 1102 range；Satellite is removing the range of GN 1104, that is, makes it possible in the range of 1102 UT；Or due to GEO It is required that serving cell/wave beam of UT 1102 will be interrupted.

The case where UT 1102 can sense another cell/wave beam and/or satellite while being connected to the first satellite Under, UT 1102 may search for default satellite and cell/wave beam signal strength for switching.It assume that UT 1102 has The location information of the satellite is to do so.The location information can be obtained from the satellite almanac data that UT 1102 possesses.Such as Fruit signal strength be it is satisfied, then UT 1102 does nothing, and wait source NAC 1106 start inter-satellite handoff procedure.

Therefore, in the example of Figure 11, both UT 1102 and source NAC 1106 will comply with the table and start to new demand servicing The switching of satellite.For this purpose, source NAC 1106 will execute hand-off process 1114.For example, source NAC 1106 can be with target NAC 1116 are communicated to start to switch.In certain aspects, this can be related to the isochronous queue between NAC 1106 and 1116 1118 (for example, Packet Service queues).Further, since knowing the time of switching in advance, it is possible to transmit Subscriber Queue in advance. Target NAC 1116 is the example of the NAC 1012 of Figure 10.

Then source NAC 1106 sends hand off signaling 1120 to UT 1102.In certain aspects, which can To include the information for enabling UT 1102 to be communicated with target NAC 1116.In certain aspects, the hand off signaling 1120 It may include new satellite and cell switch table (for example, it is source NAC 1106 received from target NAC 1116).

Then, UT 1102 from the first satellite separation 1122 and is synchronized to the second satellite.For this purpose, UT 1102 can be to mesh It marks NAC 1116 and sends the synchronous signaling 1124 for being directed to the second satellite.In certain aspects, this can be related to UT 1102 second Random access procedure is executed at satellite.

Then UT 1102 and target NAC 1116 can exchange connection signaling 1126 and 1128.In certain aspects, this can To be related to target NAC 1116 to the transmission ephemeris information of UT 1102 and request channel quality indicator from UT 1102.Some In aspect, ephemeris information is can be used to synchronize with the second satellite in UT 1102.

In addition, various entities can execute various consistency operations to ensure to be properly completed packets forwarding and execute any Required removing (for example, cache removing).

Figure 12 is the example that wherein UT 1202 sends measurement message.For example, UT 1202 can determine needs to GN 1204 Measurement message is sent, this is because the measured channel conditions (for example, signal strength) from serving satellite or target satellite It is unacceptable (for example, signal strength is too low).In this case, GN 1204 can be generated new based on measurement message Satellite and cell switch table.Then, UT 1202 and GN 1204 determines when new satellite and cell switch table is used Be transformed into next cell/wave beam and/or satellite and be transformed into where (for example, which cell/wave beam, which frequency, which Satellite).UT 1202 is the example of the UT 400 or UT 401 of Fig. 1.GN 1204 is the example of the GN 200 or GN 201 of Fig. 1.

As shown in Figure 11, source NAC 1206 sends control signaling 1208 to UT 1202.Control signaling 1208 may include Such as control information (for example, definition is left in tuning) is left in metrical information and tuning.In addition, in UT 1202 and source NAC 1206 Between exchange packet data 1210.Source NAC 1206 is the example of the NAC 1012 of Figure 10.

At some time point, triggering switching 1212.In some cases, with as indicated by satellite and cell switch table from The time corresponding current time of conversion of one satellite to next satellite constitutes handover trigger.In some cases, by The instruction adjacent satellite that UT 1202 is sent is substantially stronger (for example, strong with stronger reception signal compared with current service satellite Degree is associated) measurement message may be constructed handover trigger.

Other handover triggers can also be used.For example, GN 1204 (for example, source NAC 1206) can autonomously decide on UT 1202 need to be switched.This triggering may be as caused by such as the following terms: current service satellite is removing UT 1202 range；Satellite is removing the range of GN 1204, that is, makes it possible in the range of 1202 UT；Or due to GEO It is required that serving cell/wave beam of UT 1202 will be interrupted.

In the example in figure 12, UT 1202 can sense another cell/wave beam while being connected to the first satellite And/or satellite.Therefore, UT 1202 can execute channel quality measurement (for example, satellite signal strength measurement).For example, UT 1202 can measure 1214 signal strengths for coming from current service satellite (the first satellite) and target satellite (the second satellite).

Then UT 1202 executes measurement processing 1216, with for example any channel quality of determination, whether deficiency is (for example, signal Intensity is too low).In the insufficient situation of any channel quality, UT 1202 can choose to source NAC 1206 and send measurement message 1218.The measurement message 1218 may include such as the following terms: measurement result (for example, signal strength as unit of dB), About need the instruction of Pre-handoff time (for example, because the signal from source satellite currently too low), about needing to postpone to cut Change the time instruction or some other instruction of (for example, because the signal from target satellite is currently too low).

Therefore, it is similar to Figure 11, UT 1202 may search for default satellite and cell/wave beam signal strength for cutting It changes.Again, it can be assumed that UT 1202 has the location information of the satellite (for example, the satellite almanac data possessed from UT 1202 Middle acquisition) to do so.If signal strength be not it is satisfied, UT 1202 can to source NAC 1206 send instruction with The measurement message 1218 of the different satellite of default satellite, to trigger handoff procedure or delayed switching process in advance.

Therefore, source NAC 1206 can be received from UT 1202 based on satellite and cell switch table and source NAC 1206 Any measurement message 1218, to make about the decision that UT 1202 is switched to target satellite and target NAC 1220.Therefore, As pointed in Figure 12, source NAC 1206 will execute some hand-off process 1222.For example, source NAC 1206 can be based on measurement Message 1218 determines that switching time is to need to be shifted to an earlier date (Pre-handoff) and be also delayed by (delayed switching), or whether should Select some other satellite as target.In addition, source NAC 1206 can be communicated with target NAC 1220 to start to switch. In certain aspects, this can be related to isochronous queue 1224 (for example, Packet Service queue) between NAC 1206 and 1220.Mesh Mark NAC 1220 is the example of the NAC 1012 of Figure 10.

Then, source NAC 1206 sends hand off signaling 1226 to UT 1202.In certain aspects, the hand off signaling 1226 It may include the information that UT 1202 is communicated with target NAC 1220.In certain aspects, the hand off signaling 1226 may include new satellite and cell switch table (for example, it is source NAC 1206 received from target NAC 1220).

Then, UT 1202 from the first satellite separation 1228 and is synchronized to the second satellite.For this purpose, UT 1202 can be to mesh It marks NAC 1220 and sends the synchronous signaling 1230 for being directed to the second satellite.

Then, UT 1202 and target NAC 1220 can exchange connection signaling 1232 and 1234.In certain aspects, this It can be related to target NAC 1220 to send ephemeris information to UT 1202 and request channel quality indicator from UT 1202.Again Secondary, various entities can execute various consistency operations to ensure to be properly completed packets forwarding and execute any desired cleaning (for example, cache cleaning).

Switched using normal inter-satellite, hybrid automatic repeat-request (HARQ) process may be terminated.However, source NAC can To be accurately aware of when to switch, therefore, source NAC may insure to exhaust forward link data buffer.Further, since Switching time is known, therefore the gap for data flow can be made to minimize.

Switch between wave beam

GN and UT synchronously switches between execution cell/wave beam according to the timeline specified in satellite and cell switch table. Period or double reception ability, next cell/wave beam that UT detection is specified in satellite and cell switch table are left using tuning Existence.If UT successfully is detected next cell/wave beam, executes and switch between normal cell/wave beam, and in UT and There is no any signaling between GN.

Switch using between normal cell/wave beam, forward link HARQ process can be extended to from a cell/wave beam Next cell/wave beam.In addition, can cancel reversed when UT is from a cell/beam switchover to next cell/wave beam It assigns.For example, UT can send new request message alternatively to send reverse link data.

Make an exception scene

If UT loses current service cell/wave beam before the specified time in satellite and cell switch table expires, UT enters Radio Link Failure (RLF) mode.In RLF mode, UT can attempt to find alternative cell/wave beam or satellite (example Such as, based on the ephemeris information at UT).For example, UT can attempt to connect to the next satellite for shoulding be UT service.If UT at Another connection is established to function, then UT can send signaling message to GN to continue the communication that UT stops before RLF.

When by cell/beams serves, UT possibly can not detect in satellite and cell switch table specify it is next Cell/wave beam, but may detect that another cell/wave beam.For example, this is likely to occur in the UT fast moved (for example, attached It is connected to the UT of aircraft) on.In this case, UT can send measurement message to initiate another handoff procedure.In addition, if UT has been moved since last time sends location updating, then it can also send location updating.In response, GN can be sent Updated satellite and cell switch table.In this case, UT follows updated table.Alternatively, GN can start completely newly Handoff procedure.

Example connection mode handoff details

The each of radio connection pattern switching according to the teaching of this article will be described in further detail in 3-23 referring now to fig. 1 A aspect.The example of the call flow for various connection mode handover operations is described below.In addition, following details describes It can be used for improving several processes of performance of handoffs.In in all fields, these processes can be used for defining handover measurement, determine When triggering measures, and determines when to switch UT, or determines whether that triggering UT after the handover obtains return link synchronization.For The purpose of explanation will include the NAC for two components (BxP and AxP) for being used to control satellite and/or communicating with satellite These details are discussed under background.

Figure 13 shows the example deployment of the BxP and AxP component in satellite system.In given point in time, UT 1306 via One of one of satellite 1310 and BxP 1312 and AxP 1308 are communicated, wherein each BxP 1312 includes satellite RF subsystem System 1314 or associated with satellite RF subsystem 1314.

The combination (therefore, acronym BxP) of BxP reference BCP and BTP.In certain aspects, BxP can wrap Include the radio network elements for controlling satellite.For example, for given cell/wave beam of satellite, BxP may include for this is small Area/beams serves correspondence digital circuit set.Therefore, in certain aspects, BxP is corresponding with specific antenna.In addition, one In a little aspects, given BxP can be associated with the special frequency band of given cell/wave beam for satellite.

The combination (therefore, initial AxP) of AxP reference ACP and ATP.In certain aspects, AxP and anchor point It is corresponding.In certain aspects, anchor point can be associated with specific region (for example, administrative region, national boundary etc.).It is given AxP can be one or more satellite services.In addition, given satellite can service for one or more AxP.

In the above scene, the UT in connection mode may undergo two kinds of switching: BxP switching or AxP switching. For example, as satellite moves in non-GSO satellite system, for for give UT service cell/wave beam (and therefore and those The associated circuit of cell/wave beam and antenna) passage at any time is changed.Therefore, in certain aspects, BxP switching can With corresponding with the switching to different community/wave beam (or antenna etc.).As another example, the spy operated on the first band of frequencies Determine the rain on cell/wave beam and decline to be transposed to necessitate for cell/wave beam different frequency bands.Therefore, one In a little aspects, BxP switching can be corresponding with to being used to give the switching of cell/wave beam different frequency bands.AxP switches and to not Switching with anchor point is corresponding.For example, UT can move into different management regions, so that changing that service AxP becomes must It wants.BxP switching may be associated with AxP switching, it is also possible to not associated with it.

In certain aspects, the satellite that following disclosure solves that possibility occurs in satellite communication system, which is directed toward, to be missed Difference.These errors may be as caused by a variety of causes in system.

Figure 140 0 of Figure 14 is shown respectively from different satellite beams (the first desired beam and the second desired beam) Expection gain profile 1402 and 1404.In certain aspects, these beam gain profiles can be used to determine when by UT from One beam switchover is to next wave beam.For example, when the wave beam from current the first desired beam (source wave beam) for UT service When gain drops below the beam gain of the second desired beam (candidate target wave beam), UT can be switched.

For the first desired beam, Figure 14 is shown since satellite error in pointing may be increased by the actual beam that UT is observed Beneficial profile 1406.As indicated in Figure 14, the displacement 1408 in the gain profile as caused by satellite error in pointing is by two Gain profile intersection point between beam profile is displaced to the second intersection point 1412 from the first intersection point 1410.Therefore, in expection (ideal) At switching time 1414, the gain from the first wave beam will than expected gain 1416 it is low (indicated amount), thus to switching Can have an adverse effect.As a result, the signal quality at UT is likely lower than immediately desired signal quality before handover.To understand The certainly problem, can be based on shifting 1408 as caused by satellite error in pointing in beam profile, when by preferably switching Between displacement up to Δ (in this example embodiment, in time relatively early).Therefore, switching will occur at new switching time 1418.Such as figure Gain shown in 14, compared with the associated expected gain 1416 of expected first wave beam, at new switching time 1418 1420 can be with low Δ gain 1422.

For this purpose, UT can carry out the measurement to satellite-signal (for example, in inter-satellite and satellite) and send the letter to GN Breath.Based on these signals, GN can modify the switching time for UT.Therefore, GN can send updated switching letter to UT (for example, via subset of satellite and cell switch table or satellite and cell switch table) is ceased to solve satellite error in pointing.

In certain aspects, can make in the case where UT wherein to be realized during switching to the scene synchronous with satellite not yet Use random access procedure.Chain is returned for example, can permit UT based on random access procedure of the UT to the measurement of satellite-signal and realize Road is synchronous.

BxP switching

Logic BxP can by include the following terms 4 tuples uniquely identify: inserting of satellite network (SAN), GN antenna, Satellite beams and forward direction service link (FSL) frequency, wherein GN antenna refers to the antenna in Figure 13.If being in radio connection 4 tuple of BxP of the connection of the UT of mode changes, then BxP switching occurs for it.

Table 4 list these four types BxP switching and with the 4 tuple phase of BxP that switches for each type of BxP The example of associated variation (prominent with runic).Feeder link is exchanged and is switched, only BxP changes, rather than entire SAN.

The type of BxP switching	BxP-4 tuple changes (being indicated with runic)
		Switching in satellite	(SAN, GN antenna, satellite beams, FSL frequency)
Inter-satellite switching	(SAN, GN antenna, satellite beams, FSL frequency)
		Feeder link exchanges switching	(SAN, GN antenna, satellite beams, FSL frequency)
GN is interior, GN antenna failure shifts	(SAN, GN antenna, satellite beams, FSL frequency)

Table 4

BxP switching occurred at switching time (being represented as THO_a_priori) based on prior information, or occurred In the new switching time (being represented as THO_recalc) recalculated using UT measurement report, wherein THO_ Recalc=THO_a_priori ± Δ (for example, such as in Figure 14).

If satellite antenna error in pointing is well known to priori, UT will be based only upon its satellite switching table (for example, satellite With cell switch table) switch to initiate BxP.Otherwise, BxP switching may need UT to the measurement of Target cell and UT to source The subsequent measurement report of AxP, wherein source AxP will update UT satellite and cell switch table based on the measurement report.

BxP switching-feeder link is exchanged

Referring again to Figure 13, the first configuration 1302 and the second configuration 1304 show feeder link and exchange BxP switching.Although Each satellite has to the double-fed wired link connection of two GN, but only having a feeder link connection at any time is activity 's.The instantaneous exchange that the connection of double-fed wired link allows the movable feeder link at satellite to connect.Feeder link exchange is shown as Idempotent switching, wherein UT is switched to same satellite, same cells and identical frequency.However, it is also possible to exchange feeder link BxP switching occurs simultaneously with the cell switching for some UT, and in this case, Target cell is different from source cell.

Those callings shown in the call flow and Figure 15 discussed below and 17 of BxP switching are exchanged for feeder link Process is identical.Call flow in Figure 15 is suitable for UT and does not need to execute random access procedure after feeder link exchanges generation To realize the synchronous situation of RL.Call flow in Figure 17 be suitable for UT need feeder link exchange occur after execute with Machine access procedure is to realize the synchronous situation of RL.

BxP switching-nonrandom access

Figure 15 shows the BxP switching call flow based on nonrandom access not using UT measurement and measurement report. Typical use-case is that BxP switches in satellite.The call flow is in UT 1502, source BxP 1504, target BxP 1506, source AxP Between 1508 and GN 1510.

It is provided below to the BxP switching call flow based on nonrandom access for not utilizing UT measurement and measurement report In step description.Initial packet data stream is indicated by line 1512,1514 and 1516.

At time point 1518, source AxP 1508 is before (for example, before THO_a_priori) switch activationary time (for example, 1 second before) is pre-configured with target BxP 1506 to switch over.At step 1A, source AxP 1508 is sent out to UT 1502 Radio connection is sent to reconfigure message.At step 1B, sufficiently disappear in advance in switching activationary time to be sent to UT 1502 Breath, so that there is UT 1502 grace time to receive the message.The message may include satellite handover information, for example, conversion table Row (for example, instruction switching activationary time) and other parameters.UT 1502 starts timer T-4.If T-4 expire (for example, Switch unsuccessfully), then UT 1502 executes radio connection and re-establishes process.

At step 2A and 2B, the satellite for including in message and cell are reconfigured based on the radio connection in step 1 The uniline of conversion table, both UT 1502 and source AxP 1508 prepare at switching activationary time simultaneously (for example, in THO_a_ At priori) BxP switching.Therefore, UT 1502 prepares to be switched to target BxP 1506, and source AxP from source BxP 1504 1508 prepare UT 1502 being switched to target BxP 1506 from source BxP 1504.

At step 3, UT 1502 resets medium access control (MAC) state.Then, UT 1502 captures new cell (example Such as, FL is synchronous).

At step 4, after switching activation+minizone tuning time departure, target BxP 1506 is sent to UT 1502 RL authorization+channel quality indicator (CQI) request.RL authorization, which is addressed to source AxP 1508 and reconfigures in radio connection, to disappear UT 1502 is assigned in breath (referring to the UT identifier (UT-ID) of step 1).

At step 5, after receiving RL authorization from target BxP 1506, the stopping of UT 1502 timer T-4 (for example, Switch successfully), and reconfigured to the transmission CQI report of target BxP 1506 and radio connection and complete message (step 5A), For being transmitted to source AxP 1508 (step 5B).Radio connection reconfigures completion message and does not include information element (IE), It and is that integrality is shielded and encrypted using old key (for example, respectively Kint and Kenc).Final packet count It is indicated according to stream by line 1520,1522 and 1524.

Figure 16, which is shown, switches call flow using the BxP based on nonrandom access of UT measurement and measurement report.It is typical Use-case be in satellite BxP switch.Call flow is in UT 1602, source BxP 1604, target BxP 1606, source AxP 1608 Between GN 1610.

Here is to the step in the BxP switching call flow based on nonrandom access using UT measurement and measurement report Description.Initial packet data stream is indicated by line 1612,1614 and 1616.

When UT 1602 reconfigures message by the radio connection for being sent to UT 1602 when given source cell serves can To indicate when to carry out the measurement for next Target cell to UT 1602.Therefore, at time point 1617, when previous When in cell, source AxP 1608 can configure UT 1602 to have measurement gap information (example corresponding with time of measuring Such as, clearance mode).Source AxP 1608 can send the information, this is because satellite error in pointing may require preferably cutting It changes at time +/- Δ and satellite switching occurs, so that UT 1602 is measured and necessitated.At step 1A and 1B, source AxP 1608 sends radio connection to UT 1602 and reconfigures message.The message includes measurement gap configuration information and measurement The activation/deactivation time (other than switching activationary time described herein and other IE).At step 3,1602 basis of UT Its signal strength that Target cell is measured from the received measurement gap configuration information of source AxP 1608.Packet data streams continue into Row, represented by by line 1618,1620 and 1622.

At step 4A and 4B, UT 1602 is sent out using the report based on event to signal strength to source AxP 1608 Measurement report is sent, indicates the signal strength (for example, RSRP) of both source cell and Target cell.Source AxP 1608 is by UT 1602 are configured so that criterion of the event 1 (source cell becomes better than thresholding) as triggering measurement report.Source AxP 1608 is by door Limit setting is enough to low, so that the signal strength of source cell always greater than thresholding, is sent out to trigger UT 1602 to source AxP 1608 Send measurement report.Similarly, UT 1602 is configured so that event 4 (Target cell becomes better than thresholding) is made by source AxP 1608 For the criterion for triggering measurement report.Thresholding is arranged enough to low, so that the signal strength of Target cell is always source AxP 1608 Greater than thresholding, measurement report is sent to source AxP 1608 to trigger UT 1602.Other report criterion can also be used.

At step 5, based on UT measurement report, (referring to step 4), source AxP 1608 calculates new switching activationary time (example Such as, THO_recalc), and target is pre-configured with before (for example, before THO_recalc) new switching activationary time BxP 1606 is to switch over.For example, being based on satellite ephemeris information, beam modes and UT measurement report, source AxP 1608 can be with Prepare BxP switching to occur at +/- Δ of ideal switching time.At step 6A and 6B, source AxP 1608 is sent out to UT 1602 Radio connection is sent to reconfigure message.This document describes the contents of message comprising new switching activationary time.Optionally, The message can also include measurement gap configuration information and measurement activation/deactivation time.Sufficiently activated in advance in new switching Time to send the message to UT 1602, so that there is UT 1602 grace time to receive the message.The starting timing of UT 1602 Device T-4.If T-4 expires (for example, switching unsuccessfully), UT 1602 executes radio connection and re-establishes process.This Outside, if source AxP 1608 does not receive measurement report from UT 1602 in time, source AxP 1608 is in configuration target BxP Old switching activationary time (for example, THO_a_priori) is used when both 1606 and UT 1602 are to switch over.

The uniline of the satellite for including in message and cell switch table, UT are reconfigured based on the radio connection in step 6 Both 1602 and source AxP 1608 prepare the BxP switching at new switching activationary time (for example, THO_recalc) simultaneously.

At step 7, UT 1602 resets mac state.UT 1602 captures new cell (for example, FL is synchronous).

At step 8A, after switching activation+minizone tuning time departure, target BxP 1606 is sent out to UT 1602 Send RL authorization+CQI request.RL authorization, which is addressed to source AxP 1608 and reconfigures in radio connection, is assigned to UT in message 1602 UT-ID is (referring to step 3).

After receiving RL authorization from target BxP 1606, UT 1602 stops timer T-4 (for example, handover success), And CQI report (step 8A) is sent to 1606/ source AxP 1608 of target BxP and radio connection reconfigures and completes message (step 9A and 9B).Radio connection, which reconfigures, to be completed message and not to include IE, and is that integrality is shielded and utilize Old key (for example, respectively Kint and Kenc) is come what is encrypted.Final packet data streams are by line 1624,1626 and 1628 come table Show.

BxP switching-random access

Figure 17 shows do not utilize the BxP based on random access of UT measurement and measurement report to switch call flow.Allusion quotation The use-case of type is inter-satellite BxP switching.Call flow is in UT 1702, source BxP 1704, target BxP 1706, source AxP Between 1708 and GN 1710.

Here is to the step in the BxP switching call flow based on random access for not utilizing UT measurement and measurement report Rapid description.Initial packet data stream is indicated by line 1712,1714 and 1716.

At step 1A and 1B, source AxP 1708 is before (for example, before THO_a_priori) switch activationary time Target BxP 1706 is pre-configured with to switch over.Source AxP 1708 sends radio connection to UT 1702 and reconfigures message. This document describes the contents of message.The message sufficiently is sent to UT 1702 in switching activationary time in advance, so that UT 1702 The message is received with grace time.UT 1702 starts timer T-4.If T-4 expires (for example, switching unsuccessfully), Then UT 1702 executes radio connection and re-establishes process.

At step 2, the satellite for including in message and cell switch table are reconfigured based on the radio connection in step 1 Uniline, both UT 1702 and source AxP 1708 prepare simultaneously at (for example, at THO_a_priori) switching activationary time BxP switching.The respective operations that these operations can be similar to above in conjunction with Figure 15 discussion.

At step 3, UT 1702 resets mac state.UT 1702 captures new cell (for example, FL is synchronous).Such as bracket Represented by 1718, if step 1 does not include RA procedure command, step 4-7 is not needed.

After switching activation+inter-satellite tuning time departure, before target BxP 1706 includes dedicated to the transmission of UT 1702 FL control channel (FLCC) order of leading code signature, executes to trigger UT 1702 based on non-competing random access procedure.This So that UT 1702 is then able to realize that RL is synchronous.

At step 4, UT 1702 is sent about random access to target BxP 1706 based on non-competing random access Lead code.When receiving from UT 1702 based on non-competing random access lead code, the verifying of target BxP 1706 institute is received Signature sequence.

At step 5, target BxP 1706 to UT 1702 send be addressed to UT group (for example, RA-RNTI) appropriate with Machine access response.Random access response includes paging domain (PA), RL authorization (it includes CQI request) and interim UT-ID.

If having used dedicated preamble signature, RL authorization may include CQI request.In this case, the process Step 8B can be jumped to from time point 1720.Otherwise, operation (including step 6 and 7) and the step 8A of frame 1722 can be executed Operation.

When receiving RL authorization+CQI request (for example, in step 8A) from target BxP 1706, UT 1702 stops fixed When device T-4 (for example, handover success), and send CQI report (step 8B) to target BxP 1706.If used it is dedicated before Leading code signature, then UT 1702 also to target BxP 1706 send radio connection reconfigure complete message (step 9A), with In being transmitted to source AxP 1708 (step 9B).Radio connection, which reconfigures, to be completed message and not to include IE, and be integrality by Protection and encrypted using old key (for example, respectively Kint and Kenc).Final packet data streams by line 1724, 1726 and 1728 indicate.

Figure 18 and 19, which is shown, switches call flow using the BxP based on random access of UT measurement and measurement report.Allusion quotation The use-case of type is inter-satellite BxP switching.Call flow is in UT 1802, source BxP 1804, target BxP 1806, source AxP Between 1808 and GN 1810.

Here is the description to the step in the BxP switching based on random access using UT measurement and measurement report.Just Beginning packet data streams are indicated by line 1812,1814 and 1816.

With reference first to Figure 18, when in previous cells, source AxP 1808 is reconfigured in radio connection will in message UT 1802 is configured to have measurement gap configuration information and measurement activation/deactivation time (in addition to switching described herein activates Except time and other IE).At step 1, UT 1802 according to its from the received measurement gap configuration information of source AxP 1808 come Measure the signal strength of Target cell.Packet data streams continue, represented by by line 1818,1820 and 1822.

At step 2, UT 1802 is sent to source AxP 1808 and is surveyed using the report based on event to signal strength Amount report, indicates the signal strength (for example, RSRP) of both source cell and Target cell.Source AxP 1808 matches UT 1802 It is set to the criterion for using event 1 (source cell becomes better than thresholding) as triggering measurement report.Thresholding is arranged source AxP 1808 Enough to low, so that the signal strength of source cell is measured always greater than thresholding, to trigger UT 1802 and send to source AxP 1808 Report.Similarly, UT 1802 is configured so that event 4 (Target cell becomes better than thresholding) as triggering by source AxP 1808 The criterion of measurement report.Thresholding is arranged enough to low, so that the signal strength of Target cell is always greater than door source AxP 1808 Limit sends measurement report to source AxP 1808 to trigger UT 1802.Other report criterion can also be used.

Based on UT measurement report, (referring to step 2), source AxP 1808 calculates new switching activationary time (for example, THO_ Recalc), and before (for example, before THO_recalc) new switching activationary time it is pre-configured with target BxP 1806 To switch over.

The operation of step 3-11 is corresponding with the step 1-9 of Figure 17.Therefore, these operations be will be briefly discussed.In step 3 Place, source AxP 1808 send radio connection to UT 1802 and reconfigure message.This document describes the contents of message comprising Switch activationary time.Optionally, which can also include measurement gap configuration information and measurement activation/deactivation time.It fills Divide and send the message to UT 1802 in switching activationary time in advance, so that there is UT 1802 grace time to disappear to receive this Breath.UT 1802 starts timer T-4.If T-4 expires (for example, switching unsuccessfully), UT 1802, which is executed, to be wirelessly electrically connected Connect the process of re-establishing.In addition, if source AxP 1808 does not receive measurement report from UT 1802 in time, then source AxP 1808 when configuring both target BxP 1806 and UT 1802 to switch over using old switching activationary time (for example, THO_ a_priori)。

At step 4, the satellite for including in message and cell switch table are reconfigured based on the radio connection in step 3 Uniline, both UT 1802 and source AxP 1808 prepare at new switching activationary time (for example, THO_recalc) simultaneously BxP switching.

At step 5, UT 1802 resets mac state.UT 1802 captures new cell (for example, FL is synchronous).

Referring to Fig.1 9, after switching activation+minizone tuning time departure, target BxP 1806 is sent to UT 1802 FLCC order comprising dedicated preamble signature executes to trigger UT 1802 based on non-competing random access procedure.This makes UT 1802 is obtained to be then able to realize that RL is synchronous.

At step 6, UT 1802 is sent about random access to target BxP 1806 based on non-competing random access Lead code.When receiving from UT 1802 based on non-competing random access lead code, the verifying of target BxP 1806 institute is received Signature sequence.

At step 7, target BxP 1806 sends the random access response for being addressed to appropriate RA-RNTI to UT 1802.With Machine access response includes paging domain, RL authorization (it includes CQI request) and interim UT-ID.

When receiving RL authorization+CQI request (for example, step 10A) from target BxP 1806, UT 1802 stops timing Device T-4 (for example, switch successfully), and send CQI report (step 10B) to target BxP 1806, and to target BxP 1806/ source AxP 1808 sends radio connection and reconfigures completion message (step 11).Radio connection reconfigures completion Message do not include IE, and be integrality it is shielded and be using old key (for example, respectively Kint and Kenc) come add Close.Final packet data streams are indicated by line 1824,1826 and 1828.

BxP switching-failure transfer

In GN in the transfer of GN antenna failure, failure is had occurred and that for the antenna module of satellite service.In this case, One of two kinds of scenes are possible.In the first scene, the short interruption of UT experience connection and data service, by GN It is managed as a part of normal operating (for example, scheduling, HARQ re-transmission and ARQ by GN to FL the and RL resource for UT It retransmits).In second of scene, the loss that UT undergoes FL synchronous, or connection and data service are interrupted in the presence of significant, this causes Radio Link Failure (RLF).

AxP switching

It can execute and switch between AxP, for load balance purpose or for causing to cross over due to the change of the position UT Management region boundary and the nonstatic UT for needing to switch between AxP.AxP handoff procedure includes three different stages: AxP switching is quasi- Standby, AxP switching executes and AxP switching is completed.

Following procedure can be used for AxP switching and prepare.

Mobile (AM) Deta bearer is confirmed for radio control (RC), if applying the direct forwarding to data, It can establish the tunnel (from source AxP to the unidirectional of target AxP) of each RL-AM Deta bearer, for forward link and reversely Both link data forwardings.On the contrary, can establish each RL-AM Deta bearer if applying the indirect forwarding to data Tunnel (from source AxP via GN to the unidirectional of target AxP), with for forward link and reverse link data forwarding both.

(UM) Deta bearer mobile for RC non-acknowledgement can establish every if applying the direct forwarding to data The tunnel (from source AxP to the unidirectional of target AxP) of a RL-UM Deta bearer, to be only used for forward link data forwarding.Reverse strand Connecing data, instead of from source, AxP is not transmitted to target AxP, is alternatively sent to GN by source AxP.On the contrary, if applying pair The indirect forwarding of data can establish the tunnel (from source AxP to the unidirectional of target AxP) of each RL-UM Deta bearer, then with only It is forwarded for forward link data.Instead of from source, AxP is not transmitted to target AxP to backward chaining data, alternatively by source AxP It is sent to GN's.

Following procedure can be used for AxP switching and execute.

For RL-AM Deta bearer, the data of reverse link forwarding include sequence number (SN).The data of forward link forwarding It may include SN, or if forward link data is to receive in the case where source AxP assigns SN not yet from GN, it can Not include SN.Source AxP sends both forward link and reverse link SN and frame number (FN) information to target AxP.MAC and RL state is reset.

For RL-UM Deta bearer, the data of forward link forwarding may include SN, or if forward link data is It is received in the case that AxP assigns SN not yet in source from GN, then can not include SN.If the data of forward link forwarding Comprising SN, then target AxP should send the data to UT first (after resetting both SN and FN).State be reset (for example, Forward link and reverse link SN and FN are reset).MAC and RL state is reset.

Following procedure can be used for switching completion.

For RL-AM Deta bearer, UT can send missing/received forward link protocol Data Unit to target AxP (PDU) list, and target AxP can send missing/received reverse link PDU list to UT.For RL-AM and The forward link tunnel of each Deta bearer is transposed to target AxP from source AxP by both RL-UM Deta bearers, and in source AP Place's release UT resource.

Figure 20-22 shows in the case where no mobility management unit (MM) reorientation and relocates in no GN In the case where AxP switch call flow.Figure 20 depicts switching and prepares.Figure 21 depicts switching and executes.Figure 22, which is depicted, to be cut Change completion.Here is the description to the step in AxP switching call flow.

With reference first to Figure 18, call flow be UT 2002, source BxP 2004, target BxP 2006, source AxP 2008, Between target AxP 2012, mobility management unit (MM) 2014 (for example, MM component) and GN 2010.Initial packet data stream It is indicated by line 2016,2018 and 2020.

At step 1, source AxP 2008 is based on satellite ephemeris information and beam modes, makes UT 2002 being switched to mesh Mark the decision of cell and target AxP 2012.

At step 2, source AxP 2008 sends switching to MM 2014 and requires message, to request to target AxP 2012 The preparation of the resource at place.The message include target AxP 2012 paging domain identifier (PAI) (so that in step 3, MM 2014 can determine that it should send switching request message to which target AxP 2012), immediate data forward-path whether be To target clear container (passing transparently through MM 2014), which is taken for available (for example, via interface appropriate) and source Band handover preparation information message comprising the following terms: the radio resource configuration of the UT in source AxP 2008, source AxP 2008 In the security configuration of UT, Target cell ID (for example, target BxP ID of the instruction wave beam to be prepared) and radio bearer Information (including whether source AxP 2008 suggests carrying out forward link data forwarding).

In step 3, MM 2014 sends switching request message to target AxP 2012, to request to target AxP The preparation of resource at 2012.The message includes that switching requires the source carried in message to target clear container (referring to step 2) the Deta bearer list, to be established is (for example, the GN tunnel protocol (TP) of service quality (QoS) information, each Deta bearer is sought Location information) and security context information (for example, for target AxP derive be used for user-plane traffic and aerogram 1 during the new security key enabled jumps a pair of of NH, NCC of safety).

At step 4, when receiving switching request message from MM 2014, target AxP 2012 determines that it can establish UE context.

At step 5, target AxP 2012 sends switching request acknowledgement message to MM 2014, to exist to the notice of MM 2014 The resource prepared at target AxP 2012.The message includes target to source transparent vessel (passing transparently through MM 2014), is taken Band source AxP 2008 reconfigures message (switching command message to be used when referring to step 8) in building radio connection.It cuts Changing request confirmation message also includes the Deta bearer list to be established comprising the mesh of the specified interface about each Deta bearer Mark AxP downlink TP addressing information is (for example, for being transmitted directly to target AxP 2012 (rather than via source from GN 2010 AxP 2008) data).Switching request message can also include 2012 forward link of additional object AxP of each Deta bearer TP addressing information is (if source AxP 2008 proposes to carry out for the forward link data forwarding of Deta bearer and target AxP If 2012 receive the proposal) and each Deta bearer target AxP reverse link TP addressing information (if target AxP If 2012 request source AxP 2008 carry out the reverse link data forwarding for RL-AM Deta bearer).

At step 6, if using the indirect forwarding (for example, via specified interface) to data, MM 2014 is to GN 2010 send creation indirect data forwarding tunnel request message.The message includes Deta bearer list comprising each data are held The following information carried: the tunnel ID for being used to forward forward link data indirectly on specified interface of Deta bearer ID, target AxP Tunnel ID and IP address with IP address and target AxP for forwarding reverse link data indirectly on specified interface are (such as If fruit is applicable in).Then, GN 2010 sends creation indirect data forwarding tunnel response message to MM 2014.The message includes The following information of each Deta bearer: Deta bearer ID, GN's is used to forward forward link data indirectly on specified interface The tunnel ID and IP address for being used to forward reverse link data indirectly on specified interface of tunnel ID and IP address and GN (if applicable).

At step 7, MM 2014 sends switching command message to source AxP 2008 to exist to the notice of source AxP 2008 The resource for switching is prepared at target AxP 2012.The message includes target to source transparent vessel, is in source AxP 2008 in building radio connection reconfigure message, and (switching request acknowledgement message to be used is (referring to step when referring to step 8) Rapid 5) middle carrying.Switching command message also includes the Deta bearer list to be established.If using the direct forwarding to data (for example, via interface appropriate), then the message may include the target AxP forward link TP addressing information of each Deta bearer If (source AxP 2008 suggests carrying out for the forward link data forwarding of Deta bearer and target AxP 2012 receives this and mentions If view) and each Deta bearer target AxP reverse link TP addressing information (if 2012 request source AxP of target AxP If 2008 carry out the reverse link data forwarding for RL-AM Deta bearer).If using the indirect forwarding (example to data Such as, via specified interface), then the message may include the GN forward link TP addressing information of each Deta bearer (if source AxP 2008 propose to carry out the forward link data forwarding for Deta bearer and if target AxP 2012 receives the proposal), with And the GN reverse link TP addressing information of each Deta bearer is (if 2012 request source AxP 2008 of target AxP is directed to If the reverse link data forwarding of RL-AM Deta bearer).Referring to step 6.In addition, the message includes new satellite and cell Conversion table.When receiving switching command message, source AxP 2008 freezes the emittor/receiver shape of the Deta bearer for UT State.

At step 8, source AxP 2008 sends radio connection to UT 2002 and reconfigures message.The message includes The PCI and frequency, safety information, radio resource of new UT-ID, target BxP 2006 be public and specific configuration information (root According to needing) (for example, random access information, CQI report information) and target data carrying configuration information be (if there is from current If any change of configuration).The message also includes the new paging domain identifier for uniquely identifying target AxP 2012.? When receiving radio connection from source AxP 2008 and reconfiguring message, UE starts timer T-4.If T-4 expire (for example, Switch unsuccessfully), then UT 2002 executes radio connection and re-establishes process.

At step 9, UT 2002, which is derived, to be executed in UT 2002 to be used new when the switching of target AxP 2012 KAxP, KUPenc, Kint and Kenc.

Referring to Figure 21, for RL-AM Deta bearer, UT 2002 resets MAC and RL state (step 10).For RL-UM number According to carrying, UT 2002 resets MAC, RL and state.UT 2002 then captures new cell (for example, FL is synchronous).

At step 11 and 12, source AxP 2008 sends UT state Transfer Message to target AxP 2012 via MM 2014. Only when at least one Deta bearer is configured for RL-AM operation, AxP 2008 ability in source sends this to target AxP 2012 and disappears Breath.The message includes the following information of each RL-AM Deta bearer: reverse link SN and FN receiver state, forward link SN With the reception state of FN transmitter state and (optionally) reverse link service data unit (SDU) (if it is target AxP 2012 request source AxP 2008 forward for the reverse link data of RL-AM Deta bearer, and source AxP 2008 receives If the request).In addition, source AxP 2008 starts in order by forward chaining number for RL-AM and RL-UM Deta bearer Target AxP 2012 is transmitted to according to (being stored in 2008 Deta bearer buffer of source AxP).For RL-AM Deta bearer, this packet All forward link SDU and their SN are included, wherein UT 2002 is not for these forward links SDU come to corresponding PDU's Successful delivery is confirmed (for example, via RL status PDU).For RL-AM and RL-UM Deta bearer, this further includes from GN 2010 reach the new forward link data of specified interface.For the RL-AM Deta bearer of application reverse link data forwarding, source The forward direction reverse link SDU and their SN that AxP 2008 starts disorderly to have received is transmitted to target AxP 2012.For not applying the RL-AM Deta bearer of reverse link data forwarding, the discarding of source AxP 2008 is disorderly received The reverse link SDU arrived.For RL-UM Deta bearer, source AxP 2008 sends via specified interface to GN 2010 unordered The reverse link SDU that ground receives.Note: if source AxP 2008 is in interface appropriate using the direct forwarding to data On forward the data to target AxP 2012.

If source AxP 2008 is via GN 2010 by data on specified interface using the indirect forwarding to data 2022 are transmitted to target AxP 2012.The data forwarded are stored in (step 12) in target AxP Deta bearer buffer.

In step 12, UT 2002 sends the random access competition-based about random access to target BxP 2006 Lead code (wherein, source BxP 2004 and target BxP 2006 can be identical entity).It is connect at random being received from UT 2002 When entering lead code, the received signature sequence of the verifying of target BxP 2006 institute.If dedicated preamble is signed in target BxP 2006 In be available and assign dedicated preamble signature in step 8 for UT 2002, then UT 2002 is to target BxP 2006 The uncompetitive random access lead code about random access is sent, and thus, there is no conflict.

At step 14, target BxP 2006 sends the random access sound for being addressed to RA-RNTI appropriate to UT 2002 It answers.Random access response includes paging domain, RL authorization and interim UT-ID.

In the operation of frame 2030, UT 2002 is reconfigured to the transmission radio connection of target AxP 2012 and is completed message (step 15).The message does not include IE.Radio connection, which reconfigures, to be completed message and is that integrality is shielded, and is difference It is encrypted with new Kint and Kenc, and is the MAC control element new with UT-ID MAC control element (CE) and two (PAI MAC control element and location management message (LMI) MAC control element) is sent in combination.UT-ID MAC control member Element is comprising reconfiguring the UT-ID for being assigned to UT 2002 in message (referring to step in radio connection by target AxP 2012 8).PAI MAC control element includes the PAI for being assigned to UT 2002 by target AxP 2012 in step 8.LMI MAC control member Element includes the latest position information of UT.Target BxP 2006 parses PAI MAC control element, to determine that it should be to which AxP forwarding radio connection, which reconfigures, completes message.At this point, target BxP 2006 can send switching notice to MM 2014 Message (for example, instead of at step 19).UT 2002 starts contention resolved timer.

At step 16, target BxP 2006 is sent to UT 2002 for the RL authorization newly transmitted.RL authorization is addressed to Target AxP 2012 reconfigures the UT-ID that UT 2002 is assigned in message (referring to step 8) in radio connection.From mesh When mark BxP 2006 receives RL authorization, UT 2002 stops contention resolved timer and timer T-4.UT 2002 can start Reverse link signaling is sent on Signaling Radio Bearer (for example, SRB1 and SRB2), and at all Data Radio Bearer (DRB) Upper transmission reverse link data.UT 2002 may also begin to receive forward link signaling on SRB1 and SRB2, and all The data of forward link forwarding are received on DRB.

Referring now to Fig. 22, for the RL-AM Deta bearer of application reverse link data forwarding, target AxP 2012 is to UT 2002 status report message, the message include missing and the list (step 17) of received reverse link PDU.Target AxP 2012 (are constructed using the information in the UT state Transfer Message from source AxP 2008 via MM 2014 referring to step 11) State report.When receiving status report messages from target AxP 2012, UT 2002, which is not executed, confirms status report messages The re-transmission of any PDU of its Successful delivery.After being successfully completed reverse link PDU and retransmitting, UT 2002 starts to target AxP 2012 sends new RL-AM reverse link PDU.Since reverse link SN is kept on the basis of RL-AM Deta bearer , so the mechanism based on window is used for delivering in order and repeats to avoid by target AxP 2012.For RL-UM data Carrying, UT 2002 start to send new RL-UM reverse link PDU to target AxP 2012.The above packet data streams are by arrow 2032, it 2034 and 2036 indicates.

For all RL-AM Deta bearers, (wherein, source AxP 2008 configures UT 2002 to re-establish the phase Between send on reverse link be directed to its state report), UT 2002 to 2012 status report message of target AxP, Comprising lacking the list (step 18) with received forward link PDU.When receiving the message, target AxP 2012 start to UE send via source AxP 2008 be transmitted to target AxP 2012 forward link PDU (together with their SN and not with Their SN is together).The packet data streams are indicated by arrow 2038 and 2040.Target AxP 2012 continues to do so, until It, which receives one or more TP for the RL-AM Deta bearer from source AxP 2008, terminates label grouping.Target AxP 2012 do not execute the re-transmission that the status report messages from UT 2002 are confirmed with any PDU of its Successful delivery.Due to forward chaining Road SN is to maintain on the basis of RL-AM Deta bearer, therefore the mechanism based on window is used for passing in order by UT 2002 It send and repeats to avoid.For RL-UM Deta bearer, target AxP 2012 starts to send to UT 2002 via source AxP 2008 The forward link PDU of target AxP 2012 is transmitted to (in the case where not continuing its original SN, because SN is not in RL-UM number According to what is maintained on the basis of carrying).Target AxP 2012 continues to do so, until it is received from source AxP 2008 for each One or more TP of RL-UM Deta bearer terminate label grouping.

Step 19 can occur immediately after step 15.At step 19, target AxP 2012 is cut to the transmission of MM 2014 Notification message is changed, to have identified UT 2002 in Target cell to the notice of MM 2014 and complete to switch.This disappears PAI and Target cell ID of the breath comprising target AxP 2012 are (for example, instruction is wherein identifying the wave beam of UT 2002 Target BxP ID).

At step 20, MM 2014 sends modification bearing request message to GN 2010.The message is arranged comprising Deta bearer Table comprising the following information of each Deta bearer: Deta bearer ID's and target AxP is used for forward link user plane Tunnel ID and IP address (to uniquely identify the Deta bearer of UT).

At step 21, forward link data path is transposed to target AxP 2012 from source AxP 2008 by GN 2010, and And terminate label grouping 2042 to one or more TP that source AxP 2008 sends each Deta bearer.GN 2010 also starts directly It connects to target AxP 2012 and sends the forward link data (arrow 2044 and 2046) being intended to for UT 2002.Source AxP 2008 The TP of each Deta bearer is terminated into label packets forwarding to target AxP 2012.Each data are being received from source AxP 2008 The TP of carrying terminate label grouping when, target AxP 2012 can start to send to UT 2002 directly from GN 2010 it is received before To link data.Note: if using the direct forwarding to data, TP is terminated to mark by source AxP 2008 over appropriate interfaces Group 2048 of scoring is transmitted to target AxP 2012.If source AxP 2008 is via GN 2010 using the indirect forwarding to data Forward the data to target AxP 2012 (arrow 2050).

At step 22, GN 2010 sends modification bearing response message to MM2014.The message is arranged comprising Deta bearer Table comprising the following information of each Deta bearer: Deta bearer ID and reason (for example, request is received).

At step 23A, MM 2014 sends UE context release command message to source AxP 2008, is connect with request to S1 The release of S1 logical connection associated with UT on mouth.Then, at step 23B, source AxP 2008 sends UE to MM 2014 Context release command message, to confirm the release to the logical connection associated with UT on appropriate interface.At step 24, Source AxP 2008 discharges UT radio resource and context.At step 25, the request of indirect data forwarding tunnel is deleted (from step It is rapid 6).Final packet data streams are indicated by line 2052,2054 and 2056.

Use satellite and cell switch table

In some implementations, AxP, which can according to need using one or more of the following items, generates and/or updates Satellite and cell switch table: the position UT and/or speed, satellite position, satellite beams/cell pattern, satellite beams/cell are beaten Opening/closing scheduling or satellite error in pointing.The position of UT and/or can be by UT via wireless signaling (if specified) Message is sent.The position of satellite at any time can be obtained from almanac data.For example, in the given inserting of satellite including multiple GN In network (SAN), NOC/SOC in SAN can all AxP into SAN updated satellite ephemeris information is provided.

In some implementations, system provides the uniline that be used for satellite and cell switch table that connection mode switches to UT (for example, the row for the table 2 being set forth above).For example, UT still on the serving cell when, source AxP/BxP can be sent to UT Radio connection reconfigure include in the information element (IE) of message satellite and cell switch table uniline.Therefore, work as UT When by a cell/beams serves, UT, which can receive UT, will be used to be transformed into another cell/wave beam satellite and cell switch Information.

Configuration message when BxP switches

As described above, each satellite beams can be considered as the list of the data with their own and control channel and signal Only cell.When UT is switched to another cell from a cell, effective some radio are matched for source cell Setting parameter may change, and need to be updated for the UT operation on Target cell.

The radio message that the radio of radio parameter for serving cell reconfigures is also used to deliver for mesh Mark the updated configuration parameter of cell.

AxP by be used for Target cell reconfigure parameter send to source cell (step 1 in Figure 15, and also be applicable in Radio connection in Figure 16, Figure 17 and Figure 18 reconfigures delivering).Before handover takes place, source cell will be used for target The message that reconfigures of cell is delivered to UT, as shown in the step 1 in Figure 15.The transmission of the message is needed sufficiently in advance in cutting Completion is brought, therefore UT having time receives the message in time to allow reliably to transmit.Receiving the weight for Target cell When new configuration message, UT stores it and reconfigures once it starts communication on Target cell using this.

Switching is executed based on switching conversion table (table 3), and is switched to follow and switched defined process for BxP.? Using new configuration when switching, so that UT is suitably configured for new demand servicing cell before data and control exchange start.

It may include that specific (dedicated) and the cell of UT is specific (public) that radio for object beam, which reconfigures message, Radio parameter.These can be the following terms: dedicated MAC configuration, parameter relevant to discontinuous reception (DRX), power Headroom reporting (PHR), buffer state reports (BSR) scheduling request (SR), HARQ, SPS are configured, for the ginseng of semi-persistent scheduling Number (period, resource), PHY configuration, dedicated PHY parameter relevant to the power control of data and control channel, CQI report, spy It surveys reference signal (SRS) and SR, random access configuration, UT-ID, PCI, common radio resources configures, for random access Common parameter (for example, preamble information, power control, supervision message), physical accidental access are (for example, root sequence information and object Manage random access configuration index), reference signal power and power control, RL reference signal, ACK/NACK and CQI mapping, SRS (for example, bandwidth and sub-frame configuration), p-Max (for limiting the RL transimission power of UT in the cell).It is noted that due to UT- ID is provided to the UT for each serving cell, therefore 16 bit UT-ID may be enough uniquely to address each cell about The specified quantity of 5000 UT.

Radio link failure

In the normal operation period, when UT is from a satellite or cell/beam switchover to another satellite or cell/wave beam When, the signaling for switching is completed between the GN entity and UT for supporting switching.If UT loses before hand off signaling completion With the communication of GN, then it can fail (RLF) (for example, at UT) with declaration of radio link.RLF may occur in systems, this Be because UT it is various it is possible due to and lose to the connection of cell, for example, due to rain or snow or due to building Fading effect caused by the blocking of object or tree.In this case, RLF Restoration Mechanism can be used to re-establish and GN in UT Communication.RLF process is attempted UT reconnecting to identical source cell or different (for example, target) cells.
