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 only a part of the embodiments of the present invention, and not all of the 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.

Example 1

An embodiment of the present invention provides a method for configuring a carrier, as shown in fig. 1, the method includes:

101. a serving base station of a first communication system receives a first signaling message actively reported by a User Equipment (UE), where the first signaling message includes a Radio Frequency (RF) capability currently available to the first communication system for the UE. The terminal can work in a first communication system and a second communication system simultaneously;

it should be noted that the UE in the embodiment of the present invention may be extended to a multi-mode terminal (e.g., a mobile phone, a tablet, a portable computer, etc.), and may support simultaneous communication of multiple communication systems, where the communication systems include LTE, UMTS, GSM, etc. In the embodiment of the invention, different communication systems correspond to different communication working modes, and different standard communication protocols can be adopted.

For convenience of understanding, in the embodiment of the present invention, the UE is described as an example of supporting two communication systems at the same time, and the communication systems supported by the UE are referred to as a first communication system and a second communication system. Wherein the first communication system is a system with a carrier aggregation function, such as LTE, UMTS, etc. The active reporting includes reporting without triggering of a serving base station. The changing of the RF capability available to the UE to the first communication system comprises: the RF capability available to the first communication system changes due to the second communication system occupying a portion of the RF capability of the UE.

It should be noted that, since the UE can report its own RF capability to the serving base station actively and timely after the RF capability that the UE can use in the first communication system changes, after the serving base station obtains the RF capability that the UE can use in the first communication system, the serving base station does not need to record the RF capability of the UE to the core network device of the first communication system, that is, the core network device in the first communication system does not need to record the available RF capability that the UE changes, so that the signaling load between the network element devices can be reduced. For example, in the LTE system, the network element device that records the RF capability information of the UE is an MME (Mobility Management Entity), and the base station does not need to report the RF capability of the UE to the MME (Mobility Management Entity). It is emphasized that the core network devices recording the RF capability of the UE in different communication systems are different and will not be described herein.

102. And the serving base station updates the RF capability initially available to the first communication system by the UE to the RF capability currently available to the first communication system by the UE according to the first signaling message, and manages carriers for the UE according to the RF capability currently available to the first communication system by the UE, wherein the carrier management comprises at least one of configuration, activation and deactivation of carriers for the UE.

It should be noted that the RF capability of the UE reflects the capability of the UE to support carrier aggregation, and the base station needs to use the available RF capability of the UE as a basis when configuring the carrier for the UE. For a UE supporting multiple communication systems, the RF capabilities of the UE are shared by the multiple communication systems supported by the UE, i.e., the RF capabilities available to the UE for a communication system may vary. In the embodiment of the present invention, when the RF capability of the UE that is available for the first communication system changes, the UE can actively report its own RF capability to the serving base station of the first communication system, so that the serving base station configures a carrier for the UE according to the RF capability of the UE that is currently available for the first communication system, and manages the carrier configured for the UE, including activating, deactivating, suspending scheduling of the carrier, and the like for the carrier, without waiting for an inquiry request message about the RF capability issued by the serving base station, that is, without reporting the RF capability based on triggering of the serving base station.

In an example, when the UE needs to perform inter-frequency measurement by using a GAP (GAP), the UE may carry a GAP indication message in the first signaling message, where the GAP indication message is used to instruct a serving base station to configure a GAP on at least one carrier configured and activated for the UE; after receiving the first signaling message (carrying the GAP indication message), the serving base station may configure a GAP on at least one carrier configured and activated for the UE, so that the UE performs inter-frequency measurement using the GAP. The serving base station may also proactively configure GAPs for the UE to enable the UE to make inter-frequency measurements after the base station receives updated RF capabilities sent by the UE.

In another example, when the UE is handed over from the serving base station to the target base station, the serving base station can send the RF capability currently available to the UE for the first communication system to the target base station, so that the target base station manages carriers for the UE according to the RF capability available to the UE for the first communication system, the managing carriers including at least one of configuring, activating, and deactivating carriers for the UE.

It should be noted that, since the UE reports the RF capability of the UE to the serving base station in real time, when the RF capability of the UE that can be used in the first communication system changes and the serving base station needs to perform one or more of operations such as reconfiguration, activation, and deactivation of a carrier for the UE, an RRC (Radio Resource Control protocol) connection does not need to be reestablished between the UE and the serving base station, so that the efficiency of data transmission can be improved.

By adopting the method for configuring the carrier wave provided by the embodiment of the invention, when the RF capability of the UE which can be used for the first communication system changes, the changed available RF capability can be actively reported to the service base station, and the service base station configures the carrier wave for the UE and manages the carrier wave according to the changed RF capability, so that the carrier wave configured for the UE by the service base station can be ensured to normally work, and the communication quality is improved.

Example 2

An embodiment of the present invention provides a method for configuring a carrier, as shown in fig. 2, the method includes:

201. when the initial radio frequency capability of the UE which can be used for a first communication system changes, actively reporting a first signaling message to a service base station of the first communication system, wherein the first signaling message comprises the RF capability of the UE which can be used for the first communication system currently; the UE can work at the same time in a first communication system and a second communication system;

it should be noted that the UE in the embodiment of the present invention may be extended to a multi-mode UE (e.g., a mobile phone, a tablet, a laptop, etc.), and may support simultaneous communication of multiple communication systems, where the communication systems include LTE, UMTS, GSM, etc.

It is worth noting that, since the UE can report its own RF capability to the serving base station actively and timely after the RF capability that the UE can use in the first communication system changes, after the serving base station obtains the RF capability that the UE can use in the first communication system, the serving base station does not need to record the RF capability of the UE to the core network device of the first communication system, that is, the core network device in the first communication system does not need to record the available RF capability that the UE changes, so that the signaling load between the network element devices can be reduced. For example, in the LTE system, the network element device that records the RF capability information of the UE is an MME (mobility management entity), and the base station does not need to report the RF capability of the UE to the MME (mobility management entity). It is emphasized that the core network devices recording the RF capability of the UE in different communication systems are different and will not be described herein.

202. And the UE receives signaling of carrier management executed by the serving base station in response to the first signaling message and according to the RF capability currently available for the first communication system by the UE, wherein the carrier management comprises at least one of configuration, activation and deactivation of carriers for the UE by the serving base station.

In an example, when the UE needs to perform inter-frequency measurement by using a GAP (GAP), the UE may carry a GAP indication message in the first signaling message, where the GAP indication message is used to instruct a serving base station to configure a GAP on at least one carrier configured and activated for the UE; and the UE acquires the GAP configured on the at least one carrier by the service base station based on the GAP indication message and performs pilot frequency measurement by using the GAP.

In another example, when the UE is handed over from the serving base station to the target base station, the serving base station can send the RF capability currently available to the UE for the first communication system to the target base station, so that the target base station manages carriers for the UE according to the RF capability available to the UE for the first communication system, the management carriers including at least one of configuring, activating, and deactivating carriers for the UE.

Example 3

An embodiment of the present invention provides a method for configuring a carrier, as shown in fig. 3, the method includes:

301. the method comprises the steps that a service base station of a first communication system obtains a first indication message sent by UE, wherein the first indication message is used for representing that the UE currently works in a second communication system, and the UE can work in the first communication system and the second communication system at the same time.

It should be noted that the UE in the embodiment of the present invention may be extended to a multi-mode terminal (e.g., a mobile phone, a tablet, a portable computer, etc.), and may support simultaneous communication of multiple communication systems, where the communication systems include LTE, UMTS, GSM, etc.

For convenience of understanding, in the embodiment of the present invention, the UE is described as an example of supporting two communication systems at the same time, and the communication systems supported by the UE are referred to as a first communication system and a second communication system. Wherein the first communication system is a system with carrier aggregation features, such as LTE, UMTS, etc.

It should be noted that, the serving base station of the first communication system may receive the first indication message sent by the UE by using, but not limited to, the following methods:

acquiring the first indication message through Media Access Control (MAC) layer signaling; or

Acquiring the first indication message through a Radio Resource Control (RRC) layer signaling; or

And acquiring the first indication message through physical layer signaling.

302. The serving base station responds to the first indication message and acquires RF capability of the UE applied to the second communication system.

Specifically, the serving base station may obtain, from a core network device of the second communication system, RF capability information that the UE currently applies to the second communication system. It should be noted that the core network device in the communication system generally records the capability (including the RF capability) of the UE, for example, in the LTE system, the network element device that records the capability information of the UE is an MME, and in this embodiment, if the first communication system is LTE, the serving base station of the first communication system may obtain, from the network element device of the first communication system or the network element device of the second communication system, the RF capability information that the UE currently applies to the second communication system. Communication can be performed between core network devices in different communication systems. The core network devices recording the RF capability of the UE in different communication systems are different and will not be described herein.

Optionally, the serving base station may further obtain, through an interface with a base station of the second communication system, an RF capability currently applied to the second communication system by the UE.

303. And the serving base station determines the RF capability available for the UE to the first communication system according to the RF capability of the UE and the RF capability applied to the second communication system by the UE, and manages a carrier for the UE according to the RF capability available for the first communication system, wherein the carrier management comprises at least one of configuration, activation and deactivation of the carrier for the UE.

Specifically, before configuring a carrier for the UE, the serving base station issues an RF capability query request message to the UE to obtain RF capability information of the UE; the serving base station, after acquiring the RF capability that the UE applies to the second communication system, can calculate the remaining available RF capability of the UE as the RF capability available to the first communication system. Of course, the RF capabilities available to the first communication system may be less than the remaining available RF capabilities of the UE. When the UE simultaneously operates in two sets of communication systems, in the process of determining that the UE is available for the RF capability of the first communication system, the sum of the RF capability available for the first communication system and the RF capability applied to the second communication system may be set to be not greater than the RF capability of the UE, that is, not greater than the total RF capability that the UE can support, so that the UE can be maintained to normally operate in two sets of communication systems.

By adopting the method for configuring the carrier provided by the embodiment of the invention, the serving base station of the first communication system can determine the RF capability available for the first communication system by the UE according to the RF capability available for the second communication system by the UE, and configure the carrier for the UE according to the RF capability available for the first communication system. By adopting the method provided by the embodiment of the invention, the service base station can configure the carrier for the UE and manage the carrier according to the changed RF capability of the UE, thereby ensuring that the carrier configured for the UE can work normally and improving the communication quality.

Example 4

An embodiment of the present invention provides a method for configuring a carrier, and as shown in fig. 4, the method includes:

401. when a serving base station of a first communication system receives a first MAC CE (Control Element, Control signaling) sent by a UE, suspending scheduling of resources on a first carrier for the UE, where the first MAC CE is used to represent that the UE needs to stop transmitting data on the first carrier, and the first carrier is a carrier configured for the UE by the serving base station; the terminal can operate simultaneously in the first communication system and the second communication system. In general, the base station schedules resources on one carrier for the UE including resources used by the UE to receive or transmit data on that carrier.

Specifically, the serving base station may suspend the first carrier, i.e., suspend scheduling of resources on the first carrier for the UE.

402. And when the serving base station receives a second MAC CE sent by the UE and the first carrier is not deactivated by the serving base station, recovering to schedule resources for the UE on the first carrier, wherein the second MAC CE is used for representing that the UE can transmit data on the first carrier.

According to the method for configuring the carrier wave, provided by the embodiment of the invention, a service base station can suspend scheduling of resources on a first carrier wave for UE according to an indication message sent by the UE; when the UE can transmit data on the first carrier, the resource scheduling for the UE on the first carrier can be recovered according to the indication message of the UE. By adopting the method provided by the embodiment, when the carrier configured for the UE by the base station is suspended, the scheduling of the resource on the first carrier can be recovered under the condition that the activation condition is met, so that the throughput of user data can be ensured.

Example 5

An embodiment of the present invention provides a method for configuring a carrier, where as shown in fig. 5, the method includes:

501. when UE needs to stop transmitting data on a first carrier, a first MAC CE is sent to a service base station of a first communication system, wherein the first MAC CE is used for indicating the service base station to suspend scheduling resources on the first carrier for the UE; the terminal can operate simultaneously in the first communication system and the second communication system. The first carrier of the UE originally works in the first communication system, and currently needs to be occupied by other communication systems, if the first carrier is occupied by the second communication system, the UE needs to stop transmitting data to the serving base station of the first communication system, and then the UE sends the first MAC CE to trigger the serving base station to suspend resource scheduling.

For convenience of understanding, in the embodiment of the present invention, the UE is taken as an example to support two communication systems simultaneously, and the communication systems supported by the UE are referred to as a first communication system and a second communication system. Wherein the first communication system is a system with carrier aggregation features, such as LTE, UMTS, etc.

502. When the UE can transmit data on the first carrier, sending a second MAC CE to the serving base station, wherein the second MAC CE is used for indicating the serving base station to recover scheduling resources for the UE on the first carrier, so that the UE communicates with the serving base station through the first carrier.

According to the method for configuring the carrier wave, provided by the embodiment of the invention, when the RF capability of the UE is occupied by other communication systems and data cannot be transmitted on the first carrier wave, the resource scheduling on the first carrier wave can be suspended; when the RF capability of the UE is capable of transmitting data on the first carrier, an indication message can be sent to a serving base station of the first communication system to resume scheduling of resources on the first carrier. By adopting the method provided by the embodiment, the scheduling of the resource on the first carrier can be recovered under the condition that the UE meets the activation condition, so that the throughput of user data can be ensured.

Example 6

An embodiment of the present invention provides a method for configuring a carrier, as shown in fig. 6, the method includes:

601. the UE sends the own RF capability to a service base station of a first communication system, so that the service base station configures a carrier for the UE according to the RF capability of the UE.

For convenience of understanding, in the embodiment of the present invention, the UE is taken as an example for description, and communication systems supported by the UE are labeled as a first communication system and a second communication system.

602. And the service base station configures a first carrier for the UE according to the RF capability of the UE, and sends an activation indication message of the first carrier to the UE so as to indicate the UE to activate the first carrier.

It should be noted that, when the UE has strong RF capability for the first communication system and the traffic data volume of the UE is large, the serving base station may also configure multiple carriers for the UE.

603. And when the UE receives the activation indication message of the first carrier and the UE cannot activate the first carrier due to the fact that a second communication system occupies the RF capability of the UE, sending a first MAC CE to the serving base station, wherein the first MAC CE is used for representing that the UE stops transmitting data on the first carrier.

It should be noted that step 603 may also be a scenario as follows:

the UE receives the activation indication message of the first carrier and activates the first carrier;

in the process of communicating with a serving base station through a first carrier, when a second communication system occupies the RF capability of the UE and the UE cannot activate the first carrier, a first MAC CE is sent to the serving base station.

In an example, the UE may determine, according to the RF capability available to the first communication system, a carrier that is suggested to be activated by the serving base station, mark the carrier as a second carrier, and carry an identifier of the second carrier in the first MAC CE, so that after receiving the first MAC CE (carrying the identifier of the second carrier), the serving base station configures the second carrier for the UE and activates the second carrier. After activating the second carrier, the UE may receive, on the second carrier, resources scheduled by the serving base station for the UE.

In another example, when the UE needs to perform inter-frequency measurement by using a GAP, a GAP indication message may be carried in the first MAC CE, where the GAP indication message is used to instruct the serving base station to configure a GAP on at least one carrier configured and activated for the UE; after receiving the first MAC CE (carrying the GAP indication message), the serving base station may configure a GAP for the UE to perform inter-frequency measurement on at least one carrier configured and activated for the UE; the UE may acquire the GAP configured by the serving base station on the at least one carrier based on the GAP indication message, and perform inter-frequency measurement using the GAP.

604. And the service base station receives the first MAC CE sent by the UE, determines that the UE cannot transmit data on the first carrier, and suspends the scheduling of the resources on the first carrier for the UE.

Specifically, the serving base station may suspend the first carrier temporarily to suspend scheduling resources on the first carrier for the UE.

Optionally, the serving base station may also select to deactivate the first carrier, and the serving base station needs to send a deactivation signaling of the first carrier to the UE to indicate that the UE does not need to activate the first carrier.

It should be noted that, when the UE is handed over from the serving base station to the target base station, the serving base station may send the identifier of the first carrier to the target base station to notify the target base station that the UE cannot transmit data on the first carrier.

605. And when the second communication system stops working and releases the occupied RF capability, the UE sends a second MAC CE to the serving base station, wherein the second MAC CE is used for representing that the UE can transmit data on the first carrier.

606. And when the serving base station receives the second MAC CE sent by the UE and the first carrier is not deactivated by the serving base station, recovering to schedule resources for the UE on the first carrier, and communicating with the UE through the first carrier.

Specifically, the UE may directly activate the first carrier, or the serving base station may determine whether to resend the activation command according to needs. For example: when the amount of the service data requested by the UE is large, the serving base station may resend the activation command to the UE to instruct the UE to activate the carrier with the stronger data transmission capability.

The method for configuring the carrier wave provided by the embodiment of the invention can also realize the following scheme:

when the UE has activated the first carrier to communicate with the first communication system, if the second communication system needs to occupy the RF capability already used by the first communication system (for example, the priority of the traffic between the UE and the second communication system is higher), the UE may force the RF capability currently serving the first communication system to be yielded, and meanwhile, actively suspend the first carrier operating on the RF, and timely notify the serving base station of the first communication system to suspend the first carrier. After the second communication system stops working, the UE may directly activate the first carrier to communicate with the first communication system, or the base station determines whether to continue activating the first carrier (when the traffic of the UE is small, the base station may continue activating the first carrier; when the traffic of the UE is large, the base station may reconfigure the carrier for the UE).

According to the method for configuring the carrier wave, provided by the embodiment of the invention, when the RF capability of the UE is occupied by other communication systems and data cannot be transmitted on the first carrier wave, the service base station can be informed to suspend resource scheduling on the first carrier wave; when the RF capability of the UE is capable of transmitting data on the first carrier, an indication message can be sent to the serving base station to resume scheduling of resources on the first carrier. By adopting the method provided by the embodiment, the scheduling of the resource on the first carrier can be recovered under the condition that the UE meets the activation condition, so that the throughput of user data can be ensured.
