Description

Method for inter-system interoperation transmission of terminal equipment capability, terminal equipment and base station

Technical Field

The present invention relates to the field of communications, and in particular, to a method for interoperating and transmitting capabilities of terminal devices in different systems, a terminal device, a base station, and a computer readable storage medium.

Background

With the improvement of the wireless capability, especially the improvement of the frequency band capability, of the existing User Equipment (UE), the capability of the UE, which may also be called as the capability of the terminal Equipment (UE capability container), is getting larger. During the interworking procedure, the source radio access technology (Radio Access Technology, RAT) cell delivers RAT resources (sourcepat) and possibly UE radio capabilities of other RATs to the target RAT cell. Since a single message of UE radio capability may be too large, the source RAT must ensure that the size (size) of the UE radio capability does not cause the size of the source-to-target transparent container (source to target transparent container) to exceed the limit. For this reason, during handover of the inter RAT, the source-to-target transparent container may be caused to miss some of the UE's wireless capabilities. The problem of network interface breakdown, memory hang-up and the like can also be caused by the overlarge transparent container from the source to the target.

Detailed Description

In order that those skilled in the art will better understand the present application, reference will now be made to the accompanying drawings in which embodiments of the application are illustrated, it being apparent that the embodiments described are only some, but not all, of the embodiments of the application. Based on the embodiments of the present application, it should be understood that the present application is within the scope of protection.

In the existing networking manner, during inter-system interoperation, all wireless capabilities reported by the mobile terminal, including frequency band capabilities such as global system for mobile communications (Global System for Mobile Communications, GSM), universal mobile telecommunications system (Universal Mobile Telecommunications System, UMTS), long term evolution (Long Term Evolution, LTE), multiple-input multiple-output (multiple input multiple output, MIMO) capabilities, and the like, are formed by the source radio access technology (Radio Access Technology, RAT) cell and are sent to the target RAT cell through an inter-base station interface (e.g., an X2 interface). However, with the development of technology, the wireless capability of the UE is also larger, and the capability of reporting by some UEs with stronger capability is far beyond the signaling bearing capability of the interface between RATs. The memory of the 4G base station, the 3G base station or the 2G base station is suspended, and the whole wireless network is paralyzed. Another aspect may be that UE capabilities exceeding the limits of the interface result in some wireless capabilities not being transferred to the target RAT.

With the improvement of the wireless capability, especially the improvement of the frequency band capability, of the existing UE, the capability container of the user equipment is larger and larger. In the process of inter-RAT (inter-RAT) handover, the source RAT cell can avoid the target RAT from requesting the wireless capability information reported by the UE for the RAT resources (sourceRAT) transferred by the target RAT cell and possibly for the UE wireless capability of other RATs. Some conditions may occur for multiple network interfaces involved in Handover (HO) to communicate messages carrying UE radio capability, the source RAT must ensure that the size (size) of the UE radio capability does not cause the size of the source-to-target transparent container (source to target transparent container) to exceed the limit, since a single message of UE radio capability may be too large. For this reason, during inter-RAT handover, the source-to-target transparent container may be caused to miss some of the UE's wireless capabilities. The problem of network interface breakdown, memory hang-up and the like can also be caused by the overlarge transparent container from the source to the target.

According to the basic information issued by the network, the UE capability is selectively reported, so that inter-RAT control is controlled within a certain range, and the memory suspension of a different system caused by oversized information is avoided; avoiding the omission of the source RAT from delivering UE capability. As shown in fig. 1, is a flowchart of the third generation partnership project (3rd Generation Partnership Project,3GPP) 23.502 for 4G- >5G interoperability.

In the following, by way of example, the technical solution of the present application is further described, as shown in fig. 2, which is a schematic diagram of an embodiment of a method for inter-operating UE capability transmission by a heterogeneous system in an embodiment of the present application, and may include:

201. The source base station transmits basic information to the terminal equipment, wherein the basic information is used for the terminal equipment to report the terminal equipment capacity required by the communication between the terminal equipment and the source base station.

And the terminal equipment receives the basic information issued by the source base station.

Optionally, the basic information includes a system message block (System Information Blocks, SIB), the method further comprising: the source base station sends a first terminal equipment capability request to the terminal equipment, wherein the first terminal equipment capability request and the SIB are used for reporting the terminal equipment capability required by the terminal equipment for communication with the source base station by the terminal equipment.

202. And the terminal equipment reports the terminal equipment capacity required by the communication between the terminal equipment and the source base station according to the basic information issued by the source base station.

Optionally, the terminal device reports the terminal device capability required by the terminal device to communicate with the source base station according to the basic information issued by the source base station, including: and the terminal equipment reports the terminal equipment capability (UE capability) required by the terminal equipment for communication with the source base station according to the system message block SIB and the first terminal equipment capability request (UE capability Requset) issued by the source base station.

The terminal device may report the terminal device capabilities required for the terminal device to communicate with the source base station via first UE capability information (UE capability Information), for example. It is understood that the source base station herein is a base station selected by the terminal device from among the searched base stations for registration access.

Optionally, the reporting the terminal equipment capability required by the terminal equipment to communicate with the source base station according to the basic information issued by the source base station includes: and the terminal equipment reports the terminal equipment capacity required by the communication between the terminal equipment and the source base station according to the basic information issued by the source base station in the registration process of the access source base station.

Optionally, the base station searched by the terminal device may send out the basic information in a broadcast manner. The source base station (eNB is described as an example) in the present application may be understood as a source RAT, and the target base station (gNB is described as an example) may be understood as a target RAT.

It will be appreciated that the terminal device receives the system message block (system information blocks, SIB) message and the terminal device capability request (UE capability Request) message broadcast by the searched base station, and reports UE capability according to the system message block (system information blocks, SIB) message and the terminal device capability request (UE capability Request) message broadcast by the searched base station.

By way of example, the SIB messages broadcast by the base station may include, but are not limited to, SIB1 messages, SIB2 messages, SIB3 messages, SIB4 messages, SIB5 messages, SIB6 messages, SIB7 messages, SIB24 messages. The terminal device selects one base station from the searched base stations to access, and the selected base station is called a source base station. For example: the SIB6 and SIB7 information of the source base station broadcast the frequency band (band) information of the different system, so that the terminal equipment reports the band capabilities of the terminal such as GSM, UMTS and the like in the UE capability reported in the registration process of the access source base station; for the base stations which do not broadcast SIB6 and SIB7 messages, the capability of different systems such as GSM, UMTS and the like is not reported in the process of accessing the corresponding base station registration.

Example 1: an evolution base station (Evolutional Node B, eNB) issues an SIB5 broadcast message, and the SIB5 carries different-frequency neighbor cell information and the like; SIB5 is optionally broadcasted, and if the eNB broadcasts the SIB5 message, the terminal device needs to consider the inter-frequency neighbor cell situation in SIB5 when reporting the UE capability, and reports the related inter-frequency neighbor cell capability in SIB 5.

Example 2: the eNB issues SIB6 broadcast information, and the SIB6 carries inter-system neighbor cell information, evolved universal terrestrial radio access network (Evolved Universal Terrestrial Radio Access Network, UTRAN) cell information and the like; SIB6 is optionally broadcasted, and if the eNB broadcasts the SIB6 message, the terminal device needs to consider the inter-system neighbor cell situation in SIB6 when reporting the UE capability, and reports the related inter-system UTRAN neighbor cell capability in SIB 6.

Example 3: the eNB issues SIB7 broadcast information, the SIB7 carries inter-system neighbor cell information, global system for mobile communication (Global System for Mobile Communications, GSM)/enhanced data rates for GSM evolution (Enhanced Data Rate for GSM Evolution, EDGE) wireless communication network (GSM EDGE Radio Access Network, GERAN) cell information and the like; SIB7 is optionally broadcasted, and if the eNB broadcasts the SIB7 message, the terminal device needs to consider the inter-system neighbor cell situation in SIB7 when reporting the UE capability, and reports the related inter-system GERAN neighbor cell capability in SIB 7.

Example 4: the eNB issues an SIB24 broadcast message, and the SIB24 carries inter-system neighbor cell information, new Radio (NR) cell information and the like; SIB24 is optionally broadcasted, and if the eNB broadcasts the SIB24 message, the terminal device needs to consider the inter-system neighbor cell situation in SIB24 when reporting the UE capability, and reports the related inter-system NR neighbor cell capability in SIB 24.

It can be understood that, the UE capability is reported by the terminal device according to the SIB message issued by the base station, and through a series of internal calculations, as shown in fig. 3, a schematic diagram of the UE capability reported by the terminal device according to the SIB message issued by the base station in the embodiment of the present application is shown. In fig. 3, according to the inter-frequency and inter-system information in the system message received before, the terminal device reports the inter-frequency and inter-RAT capabilities corresponding to the UE capability identifier according to the UE capability identifier sent by the receiving network side during the access process. And for the UE capability identification which is not received, the terminal equipment does not report the corresponding different frequency and different RAT capability.

203. And the source base station sends measurement control information to the terminal equipment, wherein the measurement control information comprises a target base station identifier.

And the terminal equipment receives the measurement control information sent by the source base station. It will be appreciated that the source base station may send measurement control information to the terminal device via a radio resource control connection reconfiguration (Radio Resource Control Conection Reconfiguration, RRC Conection Reconfiguration) command. After receiving the RRC Conection Reconfiguration command, the terminal returns a radio resource control connection reconfiguration complete (RRC Conection Reconfiguration Complete) command to the source base station.

In the phase of interoperation preparation, the source base station sends measurement control information to the terminal equipment according to relevant information such as neighbor cell configuration, the measurement control information is sent to the terminal through RRC Conection Reconfiguration information, and the measurement control information carries information such as cell identification (cell ID) of the target base station, absolute radio channel number (Absolute Radio Frequency Channel Number, ARFCN) and the like.

204. And the terminal equipment performs measurement according to the measurement control information to obtain a measurement report.

205. And the terminal equipment sends the measurement report to the source base station.

And the source base station receives the measurement report sent by the terminal equipment. And the terminal equipment performs measurement reporting according to measurement control information, namely basic information of a measurement object, issued by the source base station.

206. And the source base station sends a switching request to the target base station according to the measurement report, wherein the switching request comprises terminal equipment capacity related to the communication between the terminal equipment and the target base station in the terminal equipment capacity required by the communication between the terminal equipment and the source base station.

The target base station receives a switching request sent by a source base station, wherein the switching request comprises terminal equipment capacity related to communication between the terminal equipment and the target base station in the terminal equipment capacity required by the communication between the terminal equipment and the source base station.

After receiving the measurement report reported by the terminal equipment, the source base station starts an interoperation flow, and when the source base station sends a Handover Request (Handover Request) to the target base station and transmits the terminal equipment capability through the Handover Request, only the wireless capability related to the communication between the terminal equipment and the target base station, such as the base station band capability, is transmitted, and other wireless capabilities of the mobile terminal are not transmitted. Anomalies in the various network communication interfaces due to oversize of the transfer source to target transparent container can be avoided. It may also be understood that the source RAT carries the optimized UE capability when initiating an interoperability request to the target RAT, i.e. only needs to carry the band information related to the target RAT in the neighbor cell configuration and the UE related wireless capability. And the situation that the source RAT or the target RAT crashes due to insufficient variable memory reserved by the source RAT and the target RAT because the interface bearing between different systems is overlarge caused by overlarge UE capability information is avoided.

207. And the target base station sends switching confirmation information to the source base station.

And the target base station sends switching confirmation information to the source base station after receiving the switching request sent by the source base station.

208. And the source base station sends switching indication information to the terminal equipment according to the switching confirmation information.

And the terminal equipment receives the switching indication information sent by the source base station, wherein the switching indication information can comprise the identification of the target base station.

209. And the terminal equipment sends a random access request to the target base station according to the switching indication information.

And the target base station receives the random access request sent by the terminal equipment.

210. And the target base station sends a random access response to the terminal equipment.

And the terminal equipment receives the random access response sent by the target base station.

It should be noted that, in the embodiment of the present application, the interoperability between the source base station and the target base station may be applicable to the interoperability between all different systems. For example, there may be interoperability between 4G base stations and 5G base stations, interoperability between 4G base stations and 3G base stations, interoperability between 3G base stations and 2G base stations, and so on.

It can be understood that, in the embodiment of the present application, the terminal device accesses to the target base station, which is based on non-contention random access, and the process can be divided into 2 steps. The detailed steps are as follows:

step A: the terminal device transmits an Msg (message) 1, i.e., a random access preamble (Random Access Preamble), to the target base station. It is understood that the terminal device selects PRACH (Physical Random Access Channel ) resources and transmits the selected preamble on the selected PRACH resources. The target base station may estimate the uplink Timing based on the preamble. It should be noted that, if the random access is based on non-contention, PRACH resources and preambles may be specified by the base station.

And (B) step (B): the target base station sends Msg2, namely RAR, to the terminal device.

After the terminal device sends the random access preamble, it opens a random access response time window (Random Access Response Window), and monitors the PDCCH (Physical Downlink Control Channel ) scrambled by RA-RNTI (Random Access Radio Network Temporary Identifier, random access radio network temporary identifier) in the window.

After the terminal device successfully receives the PDCCH scrambled by the RA-RNTI, the terminal device can obtain the PDSCH (Physical Downlink Shared Channel ) scheduled by the PDCCH, where the PDSCH includes an RAR (Random Access Response ), and the RAR may include, but is not limited to, the following information:

(1) The sub header of the RAR includes BI (Backoff Indicator, backoff indication) for indicating a backoff time for retransmitting Msg 1; (2) RAPID (Random Access Preamble Identity, random access preamble identification) in RAR for network to respond to received preamble index (preamble index); (3) The payload of the RAR includes a TAG (Timing Advance Group ) for adjusting the uplink timing; (4) UL grant: uplink resource indication for scheduling Msg 3; (5) TC-RNTI (Temporary Cell Radio Network Temporary Identifier, temporary cell radio network temporary identity): initial access of PDCCH (Physical Downlink Control Channel ) for scrambling Msg 4.

If the terminal equipment receives the PDCCH scrambled by the RAR-RNTI and the RAR contains the preamble index sent by the terminal equipment, the terminal equipment considers that the random access response is successfully received.

211. And the terminal equipment reports the terminal equipment capacity related to the communication between the terminal equipment and the target base station to the target base station.
