Description

Technical Field

[0001] The present application belongs to the field of mobile communication technology, and specifically relates to a wireless resource control connection method, device and terminal. Background Art

[0002] In the Multimedia Broadcast and Multicast Service (MBMS) of Long Term Evolution (LTE), the terminal, which can also be called the terminal device or the user equipment (UE), does not need to enter the RRC-Connected state to receive MBMS-related signaling or user data, so there is no RRC establishment procedure and RRC resume procedure for MBMS services. In the New Radio (NR), some target services require that the UE can only receive the signaling or user data of the MBS service in RRC-Connected, for example, the Multicast Broadcast Service (MBS), so the non-RRCConnected UE needs to initiate the RRC establishment procedure and / or RRC resume procedure.

[0003] However, the current triggering conditions of the NR RRC establishment procedure and the RRC Resume procedure may not meet the requirements of the above-mentioned target services. For example, the notification of the MBS session start is sent via SIB rather than paging, which will result in the target service being unable to be received by the UE. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a radio resource control connection method, device and terminal, which can solve the problem that the target service cannot be received by the UE.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] In a first aspect, a wireless resource control connection method is provided, which is executed by a terminal, and the method includes: acquiring first information indicated by a network side; and executing a wireless resource control connection establishment or recovery process according to a first condition.

[0007] In a second aspect, a wireless resource control connection device is provided, the device comprising: an acquisition module, used to acquire first information indicated by a network side; and an execution module, used to execute a wireless resource control connection establishment or recovery process according to a first condition.

[0008] In a third aspect, a terminal is provided, comprising a processor, a memory, and a program or instruction stored in the memory and executable on the processor, wherein the program or instruction, when executed by the processor, implements the steps of the method described in the first aspect.

[0009] In a fourth aspect, a readable storage medium is provided, on which a program or instruction is stored. When the program or instruction is executed by a processor, the steps of the method described in the first aspect are implemented, or the steps of the method described in the third aspect are implemented.

[0010] In a fifth aspect, a chip is provided, comprising a processor and a communication interface, wherein the communication interface is coupled to the processor, and the processor is used to run a network-side device program or instruction to implement the method described in the first aspect.

[0011] In an embodiment of the present application, by obtaining the first information indicated by the network side; according to the first condition, the establishment or recovery process of the radio resource control connection is performed, so that the network side can instruct the UE to perform the NR RRC establishment procedure or the RRC Resume procedure. When it is necessary to receive the target service, the network side can indicate the first information to the UE, so that the UE can perform the NR RRC establishment procedure or the RRC Resume procedure, so that the UE can enter the connected state to receive and send relevant data of the target service.

[0022] The wireless resource control connection method provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0023] Figure 2 A flow chart of a radio resource control connection method provided in an embodiment of the present application is shown. The method can be executed by a terminal. In other words, the method can be executed by software or hardware installed in the terminal. Figure 2 As shown, the method may include the following steps.

[0024] Step S201: Acquire first information indicated by the network side.

[0025] It should be understood that the first information provided by the network may include various contents, including signaling data and / or user data. When the first information is information related to MBS, the first information may include: session start / resume / deactivation / change / activation / stop / deletion notification, MBS announcement, etc. The first information may be explicitly provided to the UE by the network side, in which case the network side needs to send the first information to the UE; the first information may also be implicitly provided to the UE by the network side, in which case the network side may not send the first information to the UE.

[0026] In one implementation, the first information includes at least one of the following:

[0027] Information from upper layers, such as Non Access Stratum (NAS) signaling;

[0028] Radio Resource Control (RRC) information, such as system messages, RRC messages in the Multicast Control Channel (MCCH), Paging messages, etc.

[0029] Medium Access Control (MAC) information, such as Medium Access Control Control Element (MAC CE) signaling;

[0030] Physical layer information, for example, downlink control information (DCI).

[0031] In one implementation, the method may further include at least one of the following:

[0032] The whole or part of the first information is sent to the lower layers of the terminal through the upper layers of the terminal. In one implementation, when the first information includes information of the upper layers (such as NAS information), the whole or part of the first information can be sent to the lower layers of the terminal through the upper layers of the terminal. The part of the first information may include at least one of the following: terminal identity (UE Identity), identification information of MBS service, such as temporary mobile group identity (Temporary Mobile Group Identity, TMGI). The lower layers may include an RRC layer.

[0033] All or part of the first information is sent to the upper layers of the terminal through the lower layers of the terminal.

[0034] In one implementation, when the first information includes information of the RRC layer, all or part of the first information is sent to the upper layers of the terminal through the RRC layer of the terminal. The part of the first information may include: UE Identity, identification information of the MBS service, such as TMGI. The upper layers may be NAS layers.

[0035] In one implementation, when the first information includes information of the MAC layer, all or part of the first information is sent to the upper layers of the terminal through the MAC layer of the terminal. The part of the first information may include: UE Identity, identification information of the MBS service, such as TMGI. The upper layers may be NAS layer and RRC layer.

[0036] In one implementation, when the first information includes information of the physical layer, all or part of the first information is sent to the upper layers of the terminal through the physical layer of the terminal. The part of the first information may include: UE Identity, identification information of the MBS service, such as TMGI. The upper layers may be NAS layer and RRC layer.

[0037] Step S202: According to the first condition, a process of establishing or restoring a radio resource control connection is executed.

[0038] If the UE is in an idle state (RRC-IDLE), a radio resource control connection establishment process is initiated according to the first condition; if the UE is in an inactive state (RRC-Inactive), a radio resource control connection recovery process is initiated according to the first condition. Through the radio resource control connection establishment or recovery process, the UE will enter the radio resource control RRC-Connected, so that the first data can be sent and / or received.

[0039] It should be understood that there are many types of the first data, which are applicable to any signaling data or user data. For example, when the first data is data related to MBS, the first data may specifically be user data of MBS service; uplink signaling message sent to obtain scheduling information of MBS service; signaling sent to perform multicast service session join (session join) process, such as mb session join request message; signaling sent to perform multicast service session leave (session leave) process, such as sending mb session leave request message; signaling sent to obtain service area information of multicast broadcast service, such as multicast service area request message.

[0040] Therefore, an embodiment of the present invention provides a wireless resource control connection method, in which the terminal obtains the first information indicated by the network side; according to the first condition, the establishment or recovery process of the wireless resource control connection is performed, and the network side can instruct the UE to perform the NR RRC establishment procedure or the RRC Resume procedure. When it is necessary to receive the target service, the network side can indicate the first information to the UE, so that the UE can perform the NR RRC establishment procedure or the RRC Resume procedure, so that the UE can enter the connected state to receive and send relevant data of the target service, that is, the above-mentioned first data.

[0041] Figure 3 Another flow chart of the radio resource control connection method provided in the embodiment of the present application is shown. The method can be executed by a terminal. In other words, the method can be executed by software or hardware installed in the terminal. Figure 3 As shown, the method may include the following steps.

[0042] Step S301: Acquire first information indicated by the network side.

[0043] The step S301 may be performed by Figure 2The same or similar description of step S201 in the embodiment will not be repeated here to avoid repetition.

[0044] In one implementation, the first condition that enables the UE to initiate an establishment or recovery process of an RRC connection may include at least one of the second condition and the third condition:

[0045] The second condition may include at least one of the following:

[0046] Triggered by response to NG-RAN paging;

[0047] Triggered by upper layers;

[0048] Implement access network notification of area updates (triggered due to an RNA update).

[0049] Among them, in response to NG-RAN paging, upper layers triggering and RNA update can all trigger the RRC connection recovery process, and the conditions for triggering the RRC connection establishment process include: upper layers triggering.

[0050] The third condition may include at least one of the following:

[0051] responding to the first information, such as the resumption / establishment of the RRC connection is triggered by response to the first information (such as MBS session notification);

[0052] Receiving first data, such as the resumption / establishment of the RRC connection is triggered to receive first data (such as the MBS data);

[0053] Sending first data, such as the resumption / establishment of the RRC connection is triggered to send first data (such as the MBS data).

[0054] Step S302: Execute a process of establishing or restoring a radio resource control connection according to the priority of the third condition.

[0055] The step S302 may be performed by Figure 2 The same or similar description of step S202 in the embodiment will not be repeated here to avoid repetition.

[0056] According to the priorities of each item in the second condition and the third condition, the each item in the second condition and the third condition are sorted, and judged in turn according to the sorting results to determine whether the second condition or the third condition is satisfied, and execute the RRC connection establishment or recovery process corresponding to the second condition or the third condition.

[0057] In one implementation, the third condition may be determined first, and once the third condition is satisfied, other conditions may be skipped directly. In this case, step S302 includes:

[0058] If the third condition is met, the establishment or recovery process of the radio resource control connection corresponding to the third condition is executed, and the judgment process of whether the second condition is met is skipped, and the establishment or recovery process of the radio resource control connection corresponding to the second condition is stopped;

[0059] If the third condition is not met, it is determined whether the second condition is met, and if the second condition is met, a radio resource control connection establishment or recovery process corresponding to the second condition is executed.

[0060] Here are some examples:

[0061] if the third condition;

[0062] else if the resumption of the RRC connection is triggered by response to NG-RAN paging;

[0063] else if the resumption of the RRC connection is triggered by upperlayers;

[0064] else if the resumption of the RRC connection is triggered due to anRNA update.

[0065] For the establishment process of the radio resource control connection, the third condition is used as the first condition in the sorting result. If the third condition is not met, it is judged whether the second condition of being triggered by upper layers is met or whether the upper layers have provided an access type (AccessCategory) and at least one access identifier (Access Identities) for establishing the RRC connection. The sorting result of the items in the third condition and the second condition and the third condition is exemplified as follows:

[0066] if the third condition;

[0067] else if the upper layers provide an Access Category and one or moreAccess Identities upon requesting establishment of an RRC connection; or elseif the establishment of the RRC connection is triggered by upper layers.

[0068] In one implementation, the UE determines the third condition last; once the conditions before the third condition are met, the third condition is directly skipped. In this case, step S302 includes:

[0069] If the second condition is met, the process of establishing or restoring the wireless resource control connection corresponding to the second condition is executed, the process of judging whether the third condition is met is skipped, and the process of establishing or restoring the wireless resource control connection corresponding to the third condition is stopped; if the second condition is not met, whether the third condition is met is judged, and if the third condition is met, the process of establishing or restoring the wireless resource control connection corresponding to the third condition is executed.

[0070] For the recovery process of the radio resource control connection, in the sorting result, the third condition is sorted after each item of the second condition. An example of the sorting result of each item of the second condition and the third condition is as follows:

[0071] if the resumption of the RRC connection is triggered by response toNG-RAN paging;

[0072] else if the resumption of the RRC connection is triggered by upperlayers;

[0073] else if the resumption of the RRC connection is triggered due to anRNA update;

[0074] else if third condition.

[0075] For the establishment process of the radio resource control connection, in the sorting result, the third condition is arranged after the second condition. First, determine whether the second condition of being triggered by upper layers is satisfied or whether the upperlayers have provided an access type (Access Category) and at least one access identifier (Access Identities) for establishing the RRC connection. If neither is satisfied, then determine whether the third condition is satisfied. An example of the sorting result of each item in the second condition and the third condition is as follows:

[0076] if the upper layers provide an Access Category and one or more AccessIdentities upon requesting establishment of an RRC connection; or if the establishment of the RRC connection is triggered by upper layers;

[0077] else if first condition.

[0078] In one implementation, the third condition has the same priority as the second condition of responding to the paging of the radio access network. Step S302 includes:

[0079] If the third condition or the paging of the response radio access network in the second condition is met, the recovery process of the radio resource control connection corresponding to the third condition or the recovery process of the radio resource control connection corresponding to the paging of the response radio access network is performed, and the judgment process of whether other remaining conditions in the second condition are met is skipped, and the recovery process of the radio resource control connection corresponding to the other remaining conditions is stopped;

[0080] If neither the third condition nor the second condition of responding to the paging of the wireless access network is met, determine whether the other remaining conditions in the second condition are met, and when the other remaining conditions in the second condition are met, execute the recovery process of the wireless resource control connection corresponding to the other remaining conditions.

[0081] As for the order between the third condition and the response to the paging of the wireless access network in the second condition, the third condition can be judged first, or the response to the paging of the wireless access network in the second condition can be judged first.

[0082] For the recovery process of the radio resource control connection, an example of the ordering results of the items in the second condition and the third condition is as follows:

[0083] if the resumption of the RRC connection is triggered by response toNG-RAN paging or third condition;

[0084] else if the resumption of the RRC connection is triggered by upperlayers;

[0085] else if the resumption of the RRC connection is triggered due to anRNA update.

[0086] Another example is as follows:

[0087] if the third condition or the resumption of the RRC connection is triggered by response to NG-RAN paging;

[0088] else if the resumption of the RRC connection is triggered by upperlayers;

[0089] else if the resumption of the RRC connection is triggered due to anRNA update.

[0090] In one implementation, step S302 includes:

[0091] If the paging of the response wireless access network in the second condition is satisfied, the recovery process of the wireless resource control connection corresponding to the paging of the response wireless access network in the second condition is executed; the judgment process of whether the third condition and other remaining conditions of the second condition are satisfied is skipped, and the recovery process of the wireless resource control connection corresponding to the third condition and the recovery process of the wireless resource control connection corresponding to the other remaining conditions are stopped;

[0092] If the paging of the response radio access network in the second condition is not satisfied, then judging whether the triggering by upper layers in the second condition is satisfied, and when the triggering by upper layers is satisfied, executing the recovery process of the radio resource control connection corresponding to the triggering by upper layers, skipping the judgment process of whether the third condition and other remaining conditions of the second condition are satisfied, and stopping executing the recovery process of the radio resource control connection corresponding to the third condition and the recovery process of the radio resource control connection corresponding to other remaining conditions of the second condition;

[0093] If neither the response to the paging of the wireless access network nor the triggering by the higher layer in the second condition are met, determine whether the third condition is met, and when the third condition is met, execute the recovery process of the wireless resource control connection corresponding to the third condition, skip the determination process of whether the other remaining conditions of the second condition are met, and stop executing the recovery process of the wireless resource control connection corresponding to the second condition.

[0094] For the recovery process of the radio resource control connection, the third condition is used as the third condition in the sorting result. When the second condition before the third condition is satisfied, the judgment process of the third condition is skipped; and if the third condition is satisfied, the judgment process of the remaining second conditions is skipped. An example of the sorting result of each item in the second condition and the third condition is as follows:

[0095] if the resumption of the RRC connection is triggered by response toNG-RAN paging;

[0096] else if the resumption of the RRC connection is triggered by upperlayers;

[0097] else if the third condition;

[0098] else if the resumption of the RRC connection is triggered due to anRNA update.

[0099] In one implementation, step S302 includes:

[0100] If the paging of the response to the wireless access network in the second condition is met, the recovery process of the wireless resource control connection corresponding to the paging of the response to the wireless access network in the second condition is performed, the judgment process of whether the third condition and other remaining conditions of the second condition are met is skipped, and the recovery process of the wireless resource control connection corresponding to the third condition and the recovery process of the wireless resource control connection corresponding to the other remaining conditions are stopped;

[0101] If the response to the paging of the wireless access network in the second condition is not met, determine whether the third condition is met, and when the third condition is met, execute the recovery process of the wireless resource control connection corresponding to the third condition, skip the judgment process of whether the other remaining conditions of the second condition are met, and stop executing the recovery process of the wireless resource control connection corresponding to the other remaining conditions.

[0102] For the recovery process of the radio resource control connection, the third condition is used as the second condition in the sorting result. When the second condition before the third condition is satisfied, the judgment process of the third condition is skipped; and if the third condition is satisfied, the judgment process of the remaining second conditions is skipped. An example of the sorting result of each item in the second condition and the third condition is as follows:

[0103] if the resumption of the RRC connection is triggered by response toNG-RAN paging;

[0104] else if the third condition;

[0105] else if the resumption of the RRC connection is triggered by upperlayers;

[0106] else if the resumption of the RRC connection is triggered due to anRNA update.

[0107] Therefore, an embodiment of the present invention provides a wireless resource control connection method, in which the terminal obtains the first information indicated by the network side; according to the priority of the third condition, the second condition and the third condition are judged in turn, and the satisfied second condition or the third condition is used as the first condition to execute the wireless resource control connection establishment or recovery process, thereby ensuring that the trigger conditions of the NR RRC establishment procedure and the RRC Resume procedure meet the needs of the target service, that is, by adding a trigger condition, the target service is avoided from being unable to be received, and the service conflict problem caused by multiple trigger conditions after the new trigger condition is solved, and the UE is prevented from being unable to execute the RRC establishment procedure and the RRC Resume procedure, so that the UE can trigger the start of the wireless resource control connection establishment or recovery process at any time, enter the connected state, and smoothly receive or send the first data of the target service.

[0108] It should be noted that the execution subject of the radio resource control connection method provided in the embodiment of the present application may be a radio resource control connection device, or a control module in the radio resource control connection device for executing the method for radio resource control connection. In the embodiment of the present application, the method for executing the radio resource control connection by the radio resource control connection device is taken as an example to illustrate the apparatus for radio resource control connection provided in the embodiment of the present application.

[0110] The acquisition module 401 is used to acquire first information indicated by the network side; the execution module 402 is used to execute the establishment or recovery process of the radio resource control connection according to the first condition.

[0111] Therefore, a wireless resource control connection method and device provided by an embodiment of the present invention determines a first condition by acquiring first information indicated by the network side; according to the first condition, the wireless resource control connection establishment or recovery process is executed, thereby ensuring the triggering conditions of the NR RRC establishment procedure and the RRC Resume procedure, meeting the needs of the MBS service, and enabling the UE to enter a connected state to receive and send relevant data of the target service.
