[ detailed description ] embodiments
For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. 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 terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be understood that the term "and/or" as used herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., A and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Before the carrier determination method provided by the embodiment of the present invention, a carrier access technology in the prior art is briefly introduced:
(1) random access
The terminal devices each support a physical layer initial access procedure, which may be referred to as a random access procedure. And the network side can acquire the terminal equipment information through random access. The terminal equipment carries out random access based on the physical layer identification, and the physical layer identification at least comprises a physical layer identification domain of non-competitive access and a physical layer identification domain of competitive access.
The random access is divided into a contention access mode and a non-contention access mode.
Specifically, the contention access process may include: the terminal equipment randomly selects an access resource from the competition access resources indicated by the cell, and sends a physical layer identifier to the network side on the access resource to indicate that the random access request exists; the network side configures sending resources for the terminal equipment through the control information; the terminal equipment sends an identifier for conflict resolution on the configuration resource; the network side sends a response message to the terminal equipment, wherein the response message carries an identifier for conflict resolution reported by the terminal equipment; and the terminal equipment receives the response message and determines whether the access is successful according to the identification of the conflict resolution.
Specifically, the procedure of non-contention access may include: the terminal equipment sends the pre-configured or stored physical layer identification on the access resource based on the pre-configured or stored physical layer identification and the non-competitive access resource contained in the communication domain system broadcast message; and the network side sends a response message to the terminal equipment, wherein the response message contains the physical layer identification of the terminal equipment, so that the response is carried out on the access request of the terminal equipment.
(2) Carrier switching
The network side configures information of a plurality of carriers for the terminal equipment through system information, in the existing protocol, the network can indicate the terminal equipment to carry out carrier switching through carrier switching indication information in RRC reconfiguration information, optionally, when the carrier switching indication information contains t-Phys ID, the terminal equipment uses the t-Phys ID to carry out non-competitive access on the carrier appointed by a channel number according to the system configuration information, and otherwise, competitive access is carried out. That is, the current carrier switch is indicated by higher layer signaling
(3) RRC connection release
When the terminal equipment receives an RCC Release message sent by a network side (control node) in a connected state, all the logic channels are released, and all the data in the buffer area are cleared.
Through the above existing related carrier access technology, it can be known that the current carrier switching is indicated by a high-level signaling, and after the terminal device enters idle/inactive state (idle/inactive state), the terminal device resides in which carrier and initiates random access on that carrier, and no related signaling or indication mechanism is designed to notify the terminal device at present. Based on this, the embodiment of the present invention provides a carrier determination method, which is specifically described in detail by a plurality of embodiments as follows:
fig. 1 is a flowchart of a carrier determination method according to an embodiment of the present invention, and as shown in fig. 1, the method includes:
In this step, the network side may include a base station and other devices. The first configuration information may include a radio resource control Release message (RRC Release message).
In the embodiment of the present invention, a first configuration message is sent to a terminal device through a network side, so that the terminal device can be instructed to reside in a certain carrier based on the first configuration message, and a PRACH is sent through the certain carrier, where for determining that the terminal device resides in the certain carrier and sending the PRACH through the certain carrier, the following steps 102 to 103 are referred to.
102, the terminal device receives a first configuration message sent by a network side, wherein the first configuration message carries a carrier identifier.
In this step, the carrier identifier is a carrier identifier, where the carrier identifier includes a camping carrier identifier or a PRACH carrier identifier, or the carrier identifier includes a camping carrier identifier and a PRACH carrier identifier. That is, the at least one identity may be carried in the transmitted first configuration message.
In the embodiment of the present invention, the first configuration message is information used by the network side to instruct the terminal device to perform corresponding configuration, where the first configuration message carries a carrier identifier, so that the terminal device can determine its own camping carrier and send a PRACH carrier based on the carrier identifier through the first configuration message.
And 103, the terminal equipment determines the self resident carrier and the sending PRACH carrier based on the carrier identifier, and after entering a non-connection state, the terminal equipment resides in the resident carrier and sends PRACH on the sending PRACH carrier.
In this step, the carrier identifier includes a camping carrier identifier or a sending PRACH carrier identifier, or the carrier identifier includes a camping carrier identifier and a sending PRACH carrier identifier. A camping carrier refers to which carrier the terminal device receives system information as well as paging messages. Transmitting a PRACH carrier refers to on which carrier the terminal device transmits a PRACH.
In the embodiment of the present invention, taking the case that the carrier identifier includes a camping carrier identifier or a PRACH carrier identifier, the determining a camping carrier and transmitting a PRACH carrier in step 103 may include: if the carrier identification comprises a resident carrier identification, taking a carrier corresponding to the resident carrier identification as a resident carrier of the carrier and sending the PRACH carrier; or, if the carrier identifier includes a PRACH carrier identifier, the carrier corresponding to the PRACH carrier identifier is used as a resident carrier of the carrier and the PRACH carrier.
In this step, if the carrier identifier only includes the camping carrier identifier or the PRACH carrier identifier, the carrier identifier is used as the camping carrier and the PRACH carrier to be transmitted. It can also be understood that the camping carrier identity at this time is the same as the transmitting PRACH carrier identity.
In the embodiment of the present invention, taking the example that the carrier identifier includes a camping carrier identifier and a PRACH carrier identifier, the process of determining, by the terminal device, a camping carrier and transmitting a PRACH carrier based on the carrier identifier in step 103 may include: and determining the carrier corresponding to the resident carrier identifier as a resident carrier of the carrier, and determining the carrier corresponding to the PRACH transmission carrier identifier as a PRACH transmission carrier of the carrier.
In this step, if the carrier identifier only includes the camping carrier identifier and the sending PRACH carrier identifier, the corresponding carrier is determined according to the type to which the carrier identifier belongs. For example, when the carrier identifier includes the camping carrier identifier, the carrier corresponding to the camping carrier identifier needs to be determined as the camping carrier of the carrier. It can be understood that the identity of the camping carrier corresponds to the camping carrier, and the identity of the sending PRACH carrier corresponds to the sending PRACH carrier.
It should be noted that the camping carrier identity and the transmitting PRACH carrier identity may be the same or different.
In the implementation process of the above steps 101 to 103, as an alternative, after the network side may directly instruct the terminal device to enter an idle state/inactive state (idle/inactive state) through an RRC Release message, the network side determines a carrier where the terminal device resides and a carrier that sends a PRACH according to a carrier identifier carried in the message.
Further, as another alternative, before step 101, the method may further include:
step 201, the network side sends the carrier association relationship to the terminal device through a system broadcast message or an RRC dedicated signaling. Based on step 201, an embodiment of the present invention provides a flowchart of another carrier determining method, as shown in fig. 2, the method includes:
step 201, the network side sends the carrier association relationship to the terminal device through a system broadcast message or an RRC dedicated signaling.
In this step, the network side needs to send the carrier association relationship to the terminal device through a system broadcast message or RRC dedicated signaling.
In the embodiment of the present invention, it may be understood that, if the network side does not send the carrier association relationship to the terminal device, the carrier determination process in steps 101 to 103 is performed, and if the network side sends the carrier association relationship to the terminal device, the carrier determination process in steps 201 to 205 is performed.
Step 202, the terminal device receives a carrier association relationship sent by the network side through a system broadcast message or an RRC dedicated signaling, where the carrier association relationship includes an association relationship between a camping carrier identifier and a sending PRACH carrier identifier.
In the embodiment of the invention, the terminal equipment can determine another carrier identifier corresponding to the carrier identifier according to the acquired carrier identifier by sending the carrier association relation to the terminal equipment. For example, the acquired carrier identifier includes a camping carrier identifier 10, and it is found from the carrier association relationship that the carrier identifier corresponding to the camping carrier identifier 10 is the PRACH carrier identifier 2 to be sent.
In the embodiment of the present invention, the step is executed in step 102.
In the embodiment of the present invention, for example, taking that the obtained carrier identifier includes the camping carrier identifier 10, and finding that the carrier identifier corresponding to the camping carrier identifier 10 is the PRACH transmission carrier identifier 2 from the carrier association relationship, it can be seen that the PRACH transmission carrier identifier is different from the camping carrier identifier.
In the technical scheme provided by the embodiment of the invention, a first configuration message sent by a network side is received, the first configuration message carries a carrier identifier, a resident carrier of the first configuration message and a PRACH (physical random access channel) carrier are determined based on the carrier identifier, and after the first configuration message enters a non-connection state, the resident carrier and the PRACH carrier are resident on the resident carrier and the PRACH carrier is sent on the PRACH carrier, so that the problem that the carrier of a terminal device cannot be adjusted and indicated when the terminal device enters a non-activation state in the prior art can be solved.
On the basis, another carrier determining method is further provided in an embodiment of the present invention, and fig. 3 is a flowchart of the carrier determining method provided in an embodiment of the present invention, and is applied to a terminal device, as shown in fig. 3, the method includes:
In this step, the network side may include a base station and other devices. The second configuration information may include a radio resource control Release message (RRC Release message). It should be noted that the second configuration information and the first configuration information are both radio resource control Release messages (RRC Release messages), and only because the identifiers carried by the second configuration information and the first configuration information are different, the first configuration information and the first configuration information are used for distinguishing.
In the embodiment of the present invention, after step 302, the method further includes: and judging whether the physical layer identification is released, if so, residing on the carrier corresponding to the physical layer identification and sending the PRACH on the carrier corresponding to the physical layer identification after entering an inactive state.
In this step, the terminal device may query whether to reserve the physical layer identifier by itself, and if the physical layer identifier is reserved by itself, it indicates that the physical layer identifier is not released; if the physical layer identification is inquired, the physical layer identification is released.
In the embodiment of the invention, when the physical layer identifier is not released, the terminal equipment can reside on the carrier corresponding to the physical layer identifier and send the PRACH on the carrier corresponding to the physical layer identifier after entering the inactive state, thereby solving the problem that the prior art can not adjust and indicate the carrier of the terminal equipment when the terminal equipment enters the inactive state.
In the embodiment of the invention, the terminal equipment can initiate a non-competitive random access process on the carrier corresponding to the carrier identifier based on the carrier identifier and the physical layer identifier. For the non-contention random access procedure, reference may be made to the above description of the related art.
