Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms first, second and the like in the description and in the claims of the present invention are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the invention may be practiced other than those illustrated or described herein, and that the objects identified as "first," "second," etc. are generally a class of objects and do not limit the number of objects, e.g., a first object may be one or more.
The following describes the mobility management method provided by the embodiment of the present invention in detail through a specific embodiment and an application scenario thereof with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart of a Mobility Management method according to an embodiment of the present invention, which is applied to a communication device, where the communication device may be selected as a terminal or a core network device, and the core network device is, for example, an Access and Mobility Management Function (AMF) entity. As shown in fig. 1, the method comprises the steps of:
step 11: when a satellite handoff occurs, a plurality of registration areas of a plurality of satellites capable of covering the terminal in the target registration area sequence are kept in an active state.
Note that the target registration area sequence is a registration area sequence currently used by the terminal and the core network device. Maintaining the registration areas in the active state may be understood as that the terminal or the core network device confirms that the registration areas are in the active state, and at this time, the registration area activation process may not be initiated. For example, the terminal may perform operations, such as accessing a satellite base station, or not perform operations in the registration areas. For another example, taking the core network device as an example, the core network device may perform operations, such as paging, or not perform operations in the registration areas.
The satellite may be selected as a non-geostationary satellite, such as the 5th-Generation (5G) satellite in the fifth Generation mobile communication technology. Since the orbits of the constellation of non-geostationary satellites are predictable, the order of the satellites passing through the terrestrial fixed locations and the corresponding registration areas RA can be predetermined. In the terminal registration process, a core network device such as an AMF may distribute a registration area sequence pre-configured according to a satellite constellation and a motion trajectory for a terminal accessing a non-geostationary satellite. In addition, when the AMF detects that the terminal accesses through the satellite base station, the AMF can also allocate a corresponding registration area sequence to the terminal.
For example, according to the network topology, the satellites covering a certain area in the satellite constellation are satellite 1, satellite 2, and satellite … … in turn, and when the AMF allocates the RA sequence, the first RA includes the TAI of the current serving satellite base station, and the next RA includes the TAI of the next satellite base station to be covered in the same area. The order of the RA sequences corresponds to the order of the overhead satellites covering a certain area. The RA sequence is for example { RA }1，RA2，……，RAN}。
Step 12: after the satellite handoff is complete, only the first registration area of the handed-to satellite is maintained in an active state, and the second registration area is changed from the active state to an inactive state.
In this embodiment, the second registration area is a registration area other than the first registration area in the plurality of registration areas. Changing the second registration area from the active state to the inactive state as described above may be understood as confirming that the second registration area is changed to the inactive state.
The mobility management method of the embodiment of the invention can keep a plurality of registration areas of a plurality of satellites capable of covering the terminal in the target registration area sequence in an active state when satellite switching occurs, only a first registration area of the switched satellite is kept in the active state after the satellite switching is completed, and a second registration area is changed from the active state to an inactive state, wherein the second registration area is a registration area except the first registration area in the plurality of registration areas. Therefore, soft switching can be realized when the terminal accesses the non-geostationary satellite constellation, and the problem of communication interruption when the terminal accesses the satellite switching is avoided.
In this embodiment of the present invention, optionally, the plurality of registration areas may be two registration areas, including: a current registration area where the terminal is located when a satellite handover occurs, and a next registration area of the current registration area in the target registration area sequence. In this case, when the terminal is switched, the previous registration area, i.e., the registration area where the terminal is located before the terminal is switched, is in an inactive state, and only the next registration area, i.e., the registration area where the terminal is located after the terminal is switched, is kept in an active state.
Optionally, the validity period of each registration area in the target registration area sequence includes a start time and an end time, and the validity times of adjacent registration areas in the target registration area sequence partially overlap. Wherein the validity period is to be understood as an activation validity period. Therefore, by means of the validity period of each registration area, the overlapping interval of the front registration area and the back registration area can be flexibly designed, and further, when the terminal is switched between the two adjacent registration areas, the terminal can be ensured to be simultaneously in the two registration areas at the switching moment, and the two registration areas are in the activated state, so that the soft switching is realized, and the communication connection is ensured not to be interrupted.
For example, assuming that the validity period of the i-th registration area is [ Ts _ i, Te _ i ] and the validity period of the i + 1-th registration area is [ Ts _ i +1, Te _ i +1], the end time Te _ i of the i-th registration area is later than the start time Ts _ i +1 of the i + 1-th registration area, that is, the validity time of the i-th registration area partially overlaps with the validity time of the i + 1-th registration area.
Optionally, the duration of the partially overlapped effective time is fixed; alternatively, the duration of the partially overlapping validity times is dynamically adjusted. In this way, the duration of the overlap time of adjacent registration areas can be set as desired.
Optionally, in a case that the execution subject of this embodiment is a terminal, the mobility management method may further include: when the terminal moves out of the registration area in the target registration area sequence, a mobile registration updating request is initiated to complete a mobile registration updating process. That is, when the terminal moves out of the registration area in the target registration area sequence, i.e. the reselected cell does not belong to either the current registration area or the next registration area of the current registration area in the target registration area sequence, the mobility registration update procedure is initiated. Further, when the terminal switches between registration intervals in the target registration area sequence, no mobility registration update request is initiated because the terminal is still within a predictable region of the satellite constellation. In this way, a large amount of mobility registration update signaling can be avoided, thereby saving signaling overhead.
Optionally, in a case that the execution subject of this embodiment is a core network device, such as an AMF, the mobility management method may further include: when the terminal moves out of the registration area in the target registration area sequence, a mobile registration updating request initiated by the terminal is obtained so as to complete a mobile registration updating process. That is, when the terminal moves out of the registration area in the target registration area sequence, i.e. the reselected cell does not belong to either the current registration area or the next registration area of the current registration area in the target registration area sequence, the mobility registration update procedure is initiated. Further, when the terminal switches between registration intervals in the target registration area sequence, no mobility registration update request is initiated because the terminal is still within a predictable region of the satellite constellation. In this way, a large amount of mobility registration update signaling can be avoided, thereby saving signaling overhead.
The following describes the registration and mobility update procedure in the embodiment of the present invention with reference to fig. 2. As shown in fig. 2, the registration and mobility update procedure may include:
step 1: when a terminal, such as a User Equipment (UE), needs to register, a registration request is initiated to an old satellite (old SAT-RAN).
Step 2: the original satellite is identified as the satellite access and an initial UE message encapsulating the registration request is sent to the core network AMF.
And step 3: after receiving the indication that the UE accesses through the satellite, the AMF allocates a Registration Area (RA) sequence to the UE in a registration acceptance response message, and optionally carries a corresponding validity period of the RA. Meanwhile, the AMF locally stores an RA sequence allocated to the UE, and when the UE needs to be paged before the next registration update, the RA sequence can be used to determine a paging area.
And 4, step 4: the original satellite transmits the registration acceptance response carrying the RA sequence to the UE, and simultaneously, the original satellite can optionally carry a corresponding validity period of the RA.
And 5: at time T +1, the UE and AMF switch to the next RA in the RA sequence, and the specific procedure is detailed in step 5a, step 5b, step 5c, and step 5 d.
Step 5 a: when the UE selects a cell in the next RA, the current RA is activated at the same time as the next RA of the current RA in the RA sequence, and the UE may use it at the same time. At this time, the UE considers itself to be still in the registration state, although the mobility registration update signaling is omitted.
And step 5 b: and after the UE is switched, the former RA is changed into an inactive state, and only the latter RA is reserved as an active state.
And step 5 c: in the handover process, if the subsequent RA is included in the RA sequence sent in step 3, the AMF locally and simultaneously reserves the front and rear RA in the active state, and the AMF can be used simultaneously.
And step 5 d: when the handover is completed, the previous RA is changed to the inactive state, and only the next RA is kept to be the active state. If there are still unused RA's in the RA sequence allocated to the UE at this point, the AMF considers the UE mobility to have been updated, even if no mobility registration update signaling occurs.
Step 6: at time T +2, the UE moves out of the current RA sequence and initiates a new mobility registration update, which is detailed in step 6a, step 6b, step 6c, and step 6 d.
Step 6 a: the UE initiates a registration request to a new satellite (new SAT-RAN).
Step 6 b: the new satellite is identified as satellite access and an initial UE message encapsulating the registration request is sent to the network AMF.
Step 6 c: after receiving the indication that the UE accesses through the satellite, the AMF allocates a new Registration Area (RA) sequence to the UE in a registration acceptance response message, and optionally carries a corresponding validity period of the RA. Meanwhile, the AMF locally stores a new RA sequence assigned to the UE, which can be used to determine a paging area when the UE needs to be paged before the next registration update.
Step 6 d: the new satellite transmits a registration acceptance response carrying the new RA sequence to the UE, and optionally carries a corresponding validity period of the RA.
That is, when the UE is handed over within the RA sequence specified by the AMF at initial registration, it is not necessary to initiate the mobility registration update procedure, which is only required when the UE moves out of the current RA sequence. For initiating the mobility registration update procedure, the mobility registration update procedure may be initiated when the UE moves out of the current RA sequence, and if a validity period is allocated to each RA, the mobility registration update procedure may also be initiated when the validity period of the last RA in the RA sequence ends.
