Description

Terminal capability identifier mapping method, terminal capability query method and device

Technical Field

The present application relates to the field of wireless communication technologies, and in particular, to a terminal capability identifier mapping method, a terminal capability query method, and an apparatus.

Background

Currently, in a Long Term Evolution (LTE) system, if terminal capability information is not stored in a base station, a capability query message is sent to a terminal, so that the terminal reports the terminal capability information to the base station, and the base station stores the capability query message and forwards the capability query message to a Mobility Management Entity (MME) for storage. When the terminal moves to the coverage of other base stations, the other base stations acquire the capability information of the terminal from the MME. And if the capacity is not acquired, sending a capacity query message to the terminal. In a 5G mobile communication system, a terminal capability reporting mechanism is similar to that of an LTE system.

In the 5G mobile communication system, due to the existence of a large number of frequency band combinations, the size of some signaling messages (e.g., terminal capability information messages) is very large, exceeding the maximum length (9000 bytes) limit of Packet Data Convergence Protocol (PDCP) Protocol Data Unit (PDU). Therefore, the industry proposes an optimization scheme based on a terminal capability identity (UE capability ID), and the basic idea is that the capability of a terminal is associated with the terminal capability identity, and a base station can obtain the capability of the terminal through a mapping relation only by reporting the terminal capability identity, thereby reducing signaling overhead of an air interface and a network interface.

The terminal capability identity (UE capability ID) is divided into a manufacturer-allocated identity and an operator-allocated identity (PLMN-allocated ID). For the identifier (PLMN-allocated ID) allocated by the operator, since the range of Public Land Mobile Networks (PLMNs) is large, the frequency bands and frequency band combinations used by multiple base stations in the PLMN may be different (i.e., different terminal capability filters), which results in that the terminal capability identifiers (UE capability IDs) allocated by the operator and used by the same terminal capability in different base stations may be different, that is, the same terminal capability may correspond to the terminal capability identifiers (UE capability IDs) allocated by multiple operators in the range of one PLMN.

When a terminal moves among different base stations, if terminal capability filters (filters) used by a source base station and a target base station are different (the filters correspond to frequency bands and frequency band combinations used by the base stations), the target base station cannot directly use terminal capability information mapped by a terminal capability identifier (UE capability ID) used by the terminal at the source base station, so that the target base station needs to initiate a terminal capability query process to the terminal again, and after the terminal filters the capability by using the terminal capability filter provided by the target base station, the terminal capability information after filtering is reported to the target base station. This procedure may cause a signaling load on the interface. Therefore, how to process the change situation of the terminal capability identifier to reduce the signaling overhead is a problem to be solved at present, for the situation that the same terminal capability corresponds to a plurality of terminal capability identifiers in one PLMN.

Detailed Description

Aiming at the situation that a terminal capability identifier (UE capability ID) changes when the terminal moves among different base stations, the embodiment of the application provides a method for mapping and converting the terminal capability identifier when the terminal capability identifier changes during the movement of the terminal.

The terminal moves among different base stations, and the situation includes that the terminal is switched from a source base station to a target base station, or the situation that the terminal moves to the target base station after the source base station enters an inactive state and connection is recovered (resume) at the target base station.

Some technical terms in the embodiments of the present application will be described first.

In this embodiment, a "terminal," also referred to as User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device that provides voice and/or data connectivity to a user, for example, a handheld device, a vehicle-mounted device, etc. with a wireless connection function. Currently, some examples of terminals are: a mobile phone (mobile phone), a tablet computer, a notebook computer, a palm top computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (smart security), a wireless terminal in city (smart city), a wireless terminal in home (smart home), and the like.

The "base station" in the embodiment of the present application may be a RAN node or a base station. The RAN is the part of the network that accesses the terminal to the wireless network. A RAN node (or device) is a node (or device) in a radio access network, which may also be referred to as a base station. Currently, some examples of RAN nodes are: a gbb, a Transmission Reception Point (TRP), an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved Node B, or home Node B, HNB), a Base Band Unit (BBU), or a wireless fidelity (Wifi) Access Point (AP), etc. In addition, in one network configuration, the RAN may include a Centralized Unit (CU) node and a Distributed Unit (DU) node.

In the case that the terminal capability identity (UE capability ID) includes a manufacturer-allocated identity and an operator-allocated identity (PLMN-allocated ID), the terminal capability identity referred to in the embodiment of the present application refers to the operator-allocated terminal capability identity without specific statement.

It is to be understood that the terms "first," "second," and the like in the embodiments of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used are interchangeable under appropriate circumstances and can be implemented in sequences other than those illustrated or otherwise described herein with respect to the embodiments of the application, for example.

In the embodiment of the application, a terminal capability identifier mapping relationship is established for the condition that the same terminal capability corresponds to a plurality of terminal capability identifiers (UE capability IDs), and the mapping relationship information is stored in the terminal or the network side, so that the terminal capability identifier mapping and conversion can be performed based on the terminal capability identifier mapping relationship. The terminal capacity identifier mapping relationship comprises a plurality of different terminal capacity identifiers corresponding to the capacity of the same terminal and a corresponding relationship between each terminal capacity identifier and corresponding base station information.

Generally, terminals of the same manufacturer and model have the same capability, so that as long as the network side has the terminal capability reported by the same type of terminal, the terminal with the same capability does not need to report complete terminal capability information again, and the network can directly acquire the terminal capability information through a terminal capability identifier (UE capability ID).

In some embodiments, the terminal capability identifier mapping relationship may include one or more terminal capabilities, where the same terminal capability corresponds to multiple different terminal capability identifiers, and one terminal capability identifier corresponds to at least one base station identifier.

In other embodiments, the terminal capability identifier mapping relationship may include one or more terminal capabilities, where the same terminal capability corresponds to a plurality of different terminal capability identifiers, and one terminal capability identifier corresponds to one terminal capability filter (filter). One terminal capability filter (filter) may correspond to one or more base stations, and different base stations corresponding to the same terminal capability filter (filter) use the same frequency band or combination of frequency bands.

For example, there are 3 terminal capabilities, denoted as terminal capability 1, terminal capability 2 and terminal capability 3, respectively. There are 2 different terminal capability filters (filters) under one PLMN, which correspond to terminal capability identifier 1 and terminal capability identifier 2, respectively. Base station 1, base station 2 and base station 3 correspond to the same type of terminal capability filter and base station 4, base station 5 and base station 6 correspond to another type of terminal capability filter, i.e., base station 1, base station 2 and base station 3 use the same frequency band or combination of frequency bands and base station 4, base station 5 and base station 6 use the same frequency band or combination of frequency bands. Table 1 and table 2 show the terminal capability identification mapping tables of the above-described cases, respectively.

TABLE 1

In table 1, the terminal capability identifier of terminal capability 1 in base station 1, base station 2, and base station 3 is "terminal capability identifier 1", and the terminal capability identifier in base station 4, base station 5, and base station 6 is "terminal capability identifier 2"; similarly, the terminal capability identification of terminal capability 2 in base station 1, base station 2, and base station 3 is "terminal capability identification 3", and the terminal capability identification in base station 4, base station 5, and base station 6 is "terminal capability identification 4"; terminal capabilities 3 the terminal capabilities in base station 1, base station 2 and base station 3 are identified as "terminal capabilities identification 5" and the terminal capabilities in base station 4, base station 5 and base station 6 are identified as "terminal capabilities identification 6".

TABLE 2

In table 2, the terminal capability identifier of terminal capability 1 in the base stations (base station 1, base station 2, and base station 3) using terminal capability filter 1 is "terminal capability identifier 1", and the terminal capability identifier in the base stations (base station 4, base station 5, and base station 6) using terminal capability filter 2 is "terminal capability identifier 2"; the terminal capability identifier of the terminal capability 2 in the base station (base station 1, base station 2, and base station 3) using the terminal capability filter 1 is "terminal capability identifier 3", and the terminal capability identifier in the base station (base station 4, base station 5, and base station 6) using the terminal capability filter 2 is "terminal capability identifier 4"; the terminal capability identification of the terminal capability 3 in the base station (base station 1, base station 2, and base station 3) using the terminal capability filter 1 is "terminal capability identification 5", and the terminal capability identification in the base station (base station 4, base station 5, and base station 6) using the terminal capability filter 2 is "terminal capability identification 6".

Alternatively, the terminal capability identifier mapping relationship information stored in one base station may only include the terminal capability identifiers of the same terminal capability between the base station and the adjacent base stations of the base station.

In the embodiment of the present application, the storage form of the mapping relationship of the terminal capability identifier may be a configuration file form, or other forms, which is not limited in the embodiment of the present application.

Optionally, the terminal capability identifier mapping relationship may be stored in the base station, or may be stored in a core network element, or a server or other external storage device, or may be stored in the terminal. Wherein the core network element may include at least one of the following devices: an access and mobility Management Function (AMF), and a terminal radio Capability Management Function (UCMF). Of course, the core network element storing the terminal capability identifier mapping relationship may also be other core network elements, which is not limited in this embodiment of the present application.

Optionally, the terminal capability identifier mapping relationship may be configured through an Operation and Maintenance Administration and Maintenance (OAM) system, may be configured after being acquired from a core network element (such as an AMF or a UCMF), may be provided by a third party, may be configured after being downloaded from a network, or may be obtained through historical information statistics.

In this embodiment, when a terminal moves from a source base station to a destination base station, if terminal capability filters used by the source base station and the destination base station are different (the source base station and the destination base station use different frequency bands or different frequency band combinations), a terminal capability identifier of the terminal capability in the source base station needs to be converted into a terminal capability identifier in the destination base station, so that the destination base station applies capability information of the terminal according to the terminal capability identifier of the terminal capability in the base station. The conversion operation of the terminal capability identifier can be performed by the base station, the core network element, or the terminal.

Fig. 1 exemplarily shows a schematic flowchart of a terminal capability identifier mapping method implemented by a base station side in the embodiment of the present application, and as shown in the figure, the flowchart may include:

According to the content of the terminal capability identifier mapping relationship, in some embodiments, the terminal capability identifier mapping relationship may include a plurality of terminal capability identifiers corresponding to the same terminal capability and a base station identifier corresponding to each terminal capability identifier. In S101, the information of the second base station obtained by the first base station may include an identifier of the second base station; in S102, the first base station may query the terminal capability mapping relationship according to the first terminal capability identifier and the identifier of the second base station, so as to obtain the terminal capability identifier of the terminal capability in the second base station.

According to the content of the terminal capability identifier mapping relationship, in some embodiments, the terminal capability identifier mapping relationship may include a plurality of terminal capability identifiers corresponding to the same terminal capability, and a terminal capability filter corresponding to each terminal capability identifier. In S101, the information of the second base station obtained by the first base station may include an identifier of the second base station; in S102, the first base station may query the terminal capability mapping relationship according to the first terminal capability identifier and the terminal capability filter, so as to obtain a second terminal capability identifier corresponding to the first terminal capability identifier.

According to the process shown in fig. 1, in some embodiments, the first base station is a source base station of the target terminal, and the second base station is a destination base station of the terminal. That is, the flow shown in fig. 1 is applicable to a process in which a target terminal moves from a source base station to a destination base station, and in this process, inquiry and conversion of a terminal capability identification are performed by the source base station.

More specifically, the process of moving the target terminal from the source base station to the target base station is a process of switching the target terminal from the source base station to the target base station, and accordingly, in S101, the source base station of the target terminal determines to switch the target terminal to the target base station, and obtains a first terminal capability identifier corresponding to the capability of the target terminal and information of the target base station.

Fig. 2 is a signaling diagram illustrating terminal capability identifier mapping performed by a source base station in a handover process in the embodiment of the present application. In this embodiment, the terminal capability of a certain terminal is terminal capability 1, a terminal capability identifier mapping table is stored in the base station, in the mapping table, the terminal capability 1 corresponds to a terminal capability identifier 1(UE capability ID1) and a terminal capability identifier 2(UE capability ID2), the terminal capability identifier 1(UE capability ID1) corresponds to an identifier of the source base station, and the terminal capability identifier 2(UE capability ID2) corresponds to an identifier of the destination base station.

As shown, the process may include:

step 1: the source base station of the terminal determines to switch the terminal to the target base station, and then the source base station inquires that the terminal capability identifier used by the terminal capability 1 in the target base station is UE capability ID2 from a terminal capability identifier mapping table stored by the source base station;

step 2: a source base station sends a handover request (HandoverRequest) message to a target base station, wherein the handover request message contains handover preparation information (HandoverPreparationInformation), and the handover preparation information carries a terminal capability identifier (UE capability ID2) of the capability of the terminal in the target base station;

step 3 to step 5: a target base station sends a switching request confirmation message to a source base station, and the source base station sends a Radio Resource Control (RRC) reconfiguration message to a terminal; the terminal establishes RRC connection with a target base station and then sends an RRC reconfiguration completion message to the target base station;

step 6 to step 8: the target base station informs a core network element of path switching, the core network element sends a non-access stratum (NAS) message to the terminal, and informs the terminal of a terminal capability identifier (UE capability ID2) of the capability of the terminal in the target base station;

and step 9: the target base station informs the source base station to release the context of the terminal.
