Description

Technical Field

[0001] The present invention relates to the field of communications, and in particular to an index allocation, message sending method and device, a storage medium, and a processor. Background Art

[0002] The communication networks in the related technologies include the widely deployed fourth generation (4G) communication system and the initially deployed fifth generation (5G) communication system. Among them, the radio access network (RAN) of the 4G system is deployed with an evolved Node B (eNB) that uses the evolved Universal Terrestrial Radio Access (E-UTRA) technology on the radio interface; the RAN of the 5G system is deployed with the next generation base station (GNB) that uses the new radio (NR) access technology on the radio interface, and also with the next generation evolved base station (ng-eNB).

[0003] In a wireless access network, a system architecture in which two base stations are tightly coupled to provide communication services to user equipment (UE) is called a dual connectivity (DC) system. Figure 1 As shown, Figure 1It is a schematic diagram of the architecture of the dual-connection system in the related art. In the DC system, the base station that establishes a control plane (CP) interface with the core network for the UE is called the master base station (MN), which can also be called the first network element, and the other base station that only provides additional wireless resources for the UE is called the secondary base station (SN), which can also be called the second network element. Among them, the first and second service network elements are usually connected by a non-ideal wired interface (called X2 or Xn interface); on the wireless interface, the two service network elements can use the same or different radio access technologies (RAT), which are respectively referred to as the first RAT and the second RAT in this patent. Furthermore, the first and second service network elements both have radio resource management (RRM) functions for the UE, and accordingly, the two service network elements can establish radio resource control (RRC) entities; wherein, a signaling radio bearer (SRB) on the CP must be established between the first network element and the UE, and whether the SRB between the second network element and the UE is established is determined by the second network element.

[0004] In order to effectively manage the wireless resources of the UE, the first and second network elements need to coordinate to a certain extent, such as coordinating the wireless capabilities of the UE. In this regard, the standard organization currently defines two relevant capability parameters for the DC system: Band Combination (BC) and Baseband Processing Combination. Figure 2 As shown, Figure 2 This is a schematic diagram of information on frequency band combinations and baseband processing capability combinations in related technologies:

[0005] The BC is defined as a capability parameter that is independent of each RAT capability parameter and acts on the DC system. It is carried in a container, obtained by the first network element and forwarded to the second network element, and can be interpreted by the first and second network elements.

[0006] The BC includes a BC parameter list, wherein each item in the BC parameter list (such as BC#1) is a frequency band parameter list, and each item in the frequency band parameter list is the first and second RAT frequency bands (such as the first RAT frequency band 1, the second RAT frequency band 1) and their corresponding supported baseband processing capability parameters (the parameters may only be represented by their indexes in the respective RATs, such as BPC*1). Specifically, the first / second RAT frequency bands are the first / second RAT frequency bands supported by the UE; each item in the BC parameter list indicates that the first and second RAT frequency bands contained therein are compatible, that is, they can be configured to the UE at the same time.

[0007] The BPC is defined in the wireless capabilities of each RAT and is a large set including various baseband processing capability parameter combinations, which are obtained and read by access network elements using the corresponding RAT.

[0008] The baseband processing capability parameters may include but are not limited to the number of component carriers (CC), bandwidth class, and the number of multiple input multiple output (MIMO) layers. Each combination of baseband processing capability parameters (such as BPC*1) will be linked to a specific frequency band (such as the first RAT frequency band 1), thereby indicating the baseband processing capability that the UE can support on the frequency band.

[0009] Taking the existing X2 interface CP procedure "SN Addition Preparation" as an example, the first network element will carry at least the UE's second RAT capability, the BC applied to the DC system, and the first RAT frequency band currently used by the UE and its corresponding BPC in the addition request (SN ADDITION REQUEST) message; optionally, the message also carries the UE's measurement results of the second RAT frequency band.

[0010] After receiving the add request message, the second network element searches for a second RAT frequency band set that can be selected, and determines the second RAT frequency band and its corresponding BPC configured for the UE based on information such as measurement results, so as to further establish a service cell for the UE, wherein the service cell can be configured in the form of carrier aggregation (CA), and the CA configuration needs to depend on the BPC restriction determined to be configured for the UE (such as the number of service cells cannot exceed the number of CCs). The second network element carries the information such as the frequency band selection and wireless resource configuration in the add request confirmation (SN ADDITIONREQUEST ACKNOWLEDGE) message to reply to the first network element.

[0011] The existing CA configuration mainly refers to the service cell including the primary cell (PCell) and the secondary cell (SCell), and the primary cell established on the second network element side is also called the primary SCell (PSCell). Each SCell will be assigned a short identifier, called SCellIndex. The SCellIndex has a certain number limit. Taking the 4G system as an example, a maximum of 31 (1 to 31) can be used.

[0012] For the DC system, the SCellIndex configurations made by the two service network elements cannot be the same. However, according to the existing procedures (such as the SN Addition Preparation procedure mentioned above), before receiving the addition request confirmation message from the second network element, the first network element does not know the number of service cells that need to be established on the second network element side, making it difficult to perform effective SCellIndex allocation.

[0013] With respect to the above-mentioned technical problems in the related technologies, no effective solutions have been proposed yet. Summary of the invention

[0053] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0054] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0055] Example 1

[0056] In this embodiment, a method for operating Figure 1 The index allocation method of the architecture shown, Figure 3 is a flowchart of an index allocation method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0057] Step S302: receiving a first message sent by a first network element, wherein the first message carries a bitmap, and bits of the bitmap are used to indicate a usage status of a secondary cell index corresponding to the bit;

[0058] Step S304: assigning a secondary cell index to the secondary cell according to the bitmap.

[0059] Through the above steps, since the first message sent by the first network element is received, the first message carries a bitmap, wherein the bit positions of the bitmap are used to indicate the usage status of the secondary cell index corresponding to the bit positions, so that it is possible to obtain which secondary cell indexes are available, and then it is possible to allocate these available secondary cell indexes to the secondary cells, thereby achieving effective allocation of the secondary cell indexes. Therefore, it is possible to solve the problem in the related art that it is difficult to effectively allocate the secondary cell indexes in the DC system, thereby achieving the effect of improving the effectiveness of the allocation.

[0060] It should be noted that the length of the bitmap may be determined by the first network element or pre-agreed. It should be noted that the length of the bitmap may be determined by the first network element, which may be expressed as: selecting a length from the pre-agreed lengths of the bitmap as the length of the bitmap, but is not limited thereto. The determined length of the bitmap may be 7 bits or 32 bits, but is not limited thereto.

[0061] It should be noted that when the bit value is the first value, the usage status of the secondary cell index corresponding to the bit is occupied; when the bit value is the second value, the usage status of the secondary cell index corresponding to the bit is not occupied.

[0062] It should be noted that the above-mentioned occupied space may be used or unused but reserved for use, and the above-mentioned unoccupied space may be unused or not reserved for use.

[0063] In one embodiment of the present invention, after step S304, the method may further include: modifying the value of the bit corresponding to the secondary cell index occupied by the receiver of the first message in the bitmap from the second value to the first value; and sending the modified bitmap to the first network element.

[0064] In one embodiment of the present invention, after the above step S304, the above method may further include: when the recipient of the first message needs to reconfigure the number of secondary cells, sending a second message to the first network element, wherein the second message is used to indicate to the first network element that the recipient of the first message needs to use an additional secondary cell index.

[0065] It should be noted that the above-mentioned second message may carry at least one of the following information: a first bit map, wherein the bits corresponding to the secondary cell index occupied by the recipient of the first message and the additional secondary cell index in the first bit map have been modified to the first value; the secondary cell index occupied by the recipient of the first message; the total number of secondary cell indexes required by the recipient of the first message; and the number of secondary cell indexes additionally required by the recipient of the first message.

[0066] It should be noted that after sending the second message to the first network element, the above method may also include: when the first network element accepts the request of the recipient of the first message to use additional secondary cell indexes, receiving a third message sent by the first network element, wherein the third message also carries at least one of the following: a first bitmap; a second bitmap, wherein the value of the bit corresponding to the secondary cell index occupied by the recipient of the first message in the second bitmap is the first value and the number of bits whose value of the bit in the second bitmap is the second value is greater than or equal to the number of secondary cell indexes that the recipient of the first message needs to use additionally.

[0067] It should be noted that, when the first network element rejects the recipient of the first message's request to use an additional secondary cell index, a fourth message sent by the first network element is received; the fourth message carries one of the following information: indication information for rejecting the recipient of the first message's request to use an additional secondary cell index, and the first network element allows the recipient of the first message to use an additional secondary cell index.

[0068] It should be noted that whether the above-mentioned first network element accepts the request for the use of additional secondary cell indexes by the recipient of the first message can be indicated by a displayed indication or by an implicit indication. The displayed indication can be manifested as: receiving a designated message sent by the first network element, and the designated message is used to indicate whether the first network element accepts the request for the use of additional secondary cell indexes by the recipient of the first message; but it is not limited to this; for the implicit indication, it can be manifested as: after sending a second message to the first network element, no response message to the second message is received, which can be regarded as the first network element receiving the request for the use of additional secondary cell indexes by the recipient of the first message. When receiving the response message to the second message, it can be determined whether the first network element receives the request for the use of additional secondary cell indexes by the recipient of the first message based on the content carried in the response message, but it is not limited to this.

[0069] It should be noted that the above process may occur in the CP process of the X2 / Xn interface, such as the second network element addition preparation (SN Addition Preparation) procedure. It should be noted that the second network element may be the recipient of the above first message.

[0070] Optionally, the execution entity of the above steps may be a second network element (ie, a recipient of the above first message), etc., but is not limited thereto.

[0073] Step S404: receiving a designated bitmap sent by a designated network element, wherein the value of a bit corresponding to the secondary cell index occupied by the designated network element in the designated bitmap has been modified to a first value.

[0074] Through the above steps, since the first message is sent to the designated network element, the first message carries a bitmap, wherein the bit positions of the bitmap are used to indicate the usage status of the secondary cell index corresponding to the bit positions, so that the designated network element can obtain which secondary cell indexes are available, and then the designated network element can allocate these available secondary cell indexes to the secondary cells, thereby realizing effective allocation of the secondary cell indexes. Therefore, the problem in the related technology that it is difficult to effectively allocate the secondary cell indexes in the DC system can be solved, thereby achieving the effect of improving the effectiveness of the allocation.

[0077] It should be noted that the length of the bitmap may be determined by the first network element or pre-agreed. It should be noted that the length of the bitmap may be determined by the first network element, which may be expressed as: selecting a length from the pre-agreed lengths of the bitmap as the length of the bitmap, but is not limited thereto. The determined length of the bitmap may be 7 bits or 32 bits, but is not limited thereto.

[0078] It should be noted that when the bit value is the first value, the usage status of the secondary cell index corresponding to the bit is occupied; when the bit value is the second value, the usage status of the secondary cell index corresponding to the bit is not occupied.

[0079] It should be noted that the above-mentioned occupied space may be used or unused but reserved for use, and the above-mentioned unoccupied space may be unused or not reserved for use.

[0080] In an embodiment of the present invention, after step S402, the method may further include: when the designated network element needs to reconfigure the number of secondary cells, receiving a second message sent by the designated network element, wherein the second message is used to indicate that the designated network element needs to use an additional secondary cell index.

[0083] It should be noted that, in the case of rejecting the designated network element's request to use an additional secondary cell index, a fourth message is sent to the designated network element, wherein the fourth message carries one of the following information: indication information for rejecting the designated network element's request to use an additional secondary cell index, allowing the designated network element to use an additional secondary cell index.

[0084] It should be noted that whether the above-mentioned acceptance of the request for use of the additional secondary cell index by the designated network element can be indicated by an explicit indication or by an implicit indication. The explicit indication can be manifested as: a specified message is sent to the designated network element, and the specified message is used to indicate whether the request for use of the additional secondary cell index by the designated network element is accepted; but it is not limited to this; for the implicit indication, it can be manifested as: not sending a response message to the second message to the designated network element within a predetermined time after receiving the second message sent by the designated network element, which can be regarded as receiving the request for use of the additional secondary cell index by the designated network element, and when sending a response message to the second message to the designated network element, the content carried in the response message indicates whether the request for use of the additional secondary cell index by the designated network element is received, but it is not limited to this.

[0085] It should be noted that the above-mentioned designated message may be the same message as the above-mentioned third message or may be a different message, and the above-mentioned designated message may be the same message as the above-mentioned fourth message or may be a different message, and is not limited thereto.

[0086] It should be noted that the above process may occur in the CP process of the X2 / Xn interface, such as the second network element addition preparation (SN Addition Preparation) procedure.

[0087] It should be noted that the execution subject of the above message sending method can be the first network element, but is not limited to this.

[0088] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a magnetic disk, or an optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods described in each embodiment of the present invention.

[0118] Example 3

[0119] An embodiment of the present invention further provides a storage medium, which includes a stored program, wherein when the program is run, any of the above methods is executed.

[0120] Optionally, in this embodiment, the above-mentioned storage medium may include but is not limited to: a USB flash drive, a read-only memory (ROM), a random access memory (RAM), a mobile hard disk, a magnetic disk or an optical disk, and other media that can store program codes.

[0121] An embodiment of the present invention further provides a processor, which is used to run a program, wherein the program executes the steps in any of the above methods when running.

[0122] Optionally, the specific examples in this embodiment may refer to the examples described in the above embodiments and optional implementation modes, and this embodiment will not be described in detail here.

[0123] In order to better understand the embodiments of the present invention, the present invention is further explained below in conjunction with preferred embodiments.

[0124] Based on the above Figure 1 The system architecture and CP mode shown in the figure, the method provided by this preferred embodiment includes:

[0125] The first network element carries a bitmap (equivalent to the bitmap in the above embodiment) in the interface message (equivalent to the first message in the above embodiment) sent to the second network element. The function of the bitmap is to enable the second network element to know which SCellIndex is available. Specifically, the bitmap has the following characteristics:

[0126] Granularity: The bitmap may be at the UE level, that is, for the UE, only one bitmap needs to be coordinated and maintained between service network elements.

[0127] Length: The length of the bitmap is the maximum number of SCellIndex that the access network can configure for the UE. It should be noted that the length can be determined by the first network element or pre-agreed. It should be noted that the length of the above-mentioned bitmap is determined by the first network element and can be expressed as: selecting a length from the pre-agreed bitmap lengths as the length of the above-mentioned bitmap, but is not limited to this. The determined length of the above-mentioned bitmap can be 7 bits or 32 bits, but is not limited to this.

[0128] Numerical value: On each bit of the bitmap, 0 / 1 is used to indicate to the receiving network element that the SCellIndex corresponding to its sequence is available (equivalent to unoccupied in the above embodiment) / unavailable (equivalent to occupied in the above embodiment). In this preferred embodiment, 0 (equivalent to the first value in the above embodiment) indicates unavailable, and 1 (equivalent to the second value in the above embodiment) indicates available. For example, in the bitmap sent by the first network element to the second network element, the SCellIndex corresponding to 0 (unavailable bit) indicates that the first network element has been (or reserved) used, that is, the second network element cannot be used anymore; the SCellIndex corresponding to 1 (available bit) indicates that the first network element has not been occupied yet, that is, the second network element can be used. Among them, "use" means that the network element can allocate the SCellIndex to a certain SCell of the UE.

[0129] According to the information such as the second RAT frequency band and its corresponding BPC, the second network element determines the CA configuration and allocates SCellIndex for each SCell according to the bitmap. The second network element changes the corresponding position of the SCellIndex occupied by its own side (or reserved for occupation, but the total number should not exceed the number of CCs limited in the currently selected BPC) in the bitmap from available to unavailable ("1" to "0"), and carries it in the corresponding response message to reply to the first network element.

[0130] The above message interaction may occur in the CP procedure of the X2 / Xn interface, such as the SN Addition Preparation procedure.

[0131] When the second network element has a reconfiguration requirement for the number of SCells (the reconfiguration requirement at least exceeds the used SCellIndex indicated by the second network element in the previous application), the second network element needs to trigger a re-coordination procedure for SCellIndex. Specifically, the second network element sends a modification request message (equivalent to the second message in the above embodiment) to the first network element, and the purpose of the modification request message is to indicate to the first network element the SCellIndex that needs to be used additionally. The information that can be carried in the modification request message may include but is not limited to:

[0132] The bitmap (equivalent to the first bitmap in the above embodiment) is based on the latest bitmap value known by the second network element and according to the SCellIndex that needs to be used additionally, the second network element modifies the remaining SCellIndex available bits to non-available bits;

[0133] or

[0134] The number of SCellIndex that the second network element needs to use additionally.

[0135] After receiving the modification request message, when the first network element decides to accept the second network element's demand for the use of the additional SCellIndex, the information carried in the modification confirmation message replied to the second network element corresponding to the modification request message may include but is not limited to:

[0136] The confirmation of the received bitmap may be explicitly indicated by an indication (or no indication, i.e., implicitly indicating acceptance).

[0137] Furthermore, the first network element may also carry the bitmap and not modify the value of the bitmap that the second network element has indicated as a non-usable bit. For example, if the first network element also has an additional SCellIndex that needs to be occupied, the first network element may modify the remaining available bits in the bitmap to non-usable bits.

[0138] or

[0139] The bitmap, wherein the number of available bits remaining is at least equal to the number of SCellIndex required to be additionally used indicated by the second network element.

[0140] If the first network element rejects the use request of the second network element, the modification confirmation message may carry a rejection indication, or the first network element allows the second network element to use additional SCellIndex (i.e., the number is less than the number requested by the second network element). Even, the first network element may decide to release or switch the second network element.

[0141] The above message interaction may occur in the CP procedure of the X2 / Xn interface, such as a second network element modification (SN initiated SN Modification) procedure triggered by the second network element.

[0142] Through the above preferred embodiments, the service network elements can effectively coordinate and re-coordinate the cell parameters, so that the limited cell parameter space can be fully and reasonably used, and the service network element can make accurate and reasonable wireless resource configuration for the UE, thereby improving the performance of the UE.

[0143] Preferred embodiment 1

[0144] Taking the second network element addition procedure and the SCell Index being at most 7 (1 to 7) as an example, the coordination and initial configuration of SCellIndex between the first and second network elements are described. For the BC and BPC supported by the UE, please refer to Figure 2 The hint, Figure 7 1 is a flow chart of a method according to a preferred embodiment of the present invention, the method comprising:

[0145] Step 1: The first network element sends a second network element addition request to the second network element: The UE in the RRC connected state is configured with 3 service cells on the first network element side, among which the frequency of PCell belongs to the first RAT band 1, and 2 SCells are configured with SCellIndex of 1 / 2 respectively. Based on information such as the current wireless environment and / or resource status, the first network element selects a suitable access network node to add to the UE as a second network element. Before sending an interface message (such as an SN AdditionRequest message) to the second network element, the first network element has obtained the UE's wireless capabilities in the first and second RATs from the UE or the core network, as well as the BC capability parameters between the two RATs required to configure the DC architecture.

[0146] In the SN Addition Request message, in addition to carrying the existing necessary information elements, such as the UE's second RAT wireless capability, the BC capability applied to the DC architecture, the first RAT frequency band currently configured by the first network element for the UE to use and its corresponding BPC (such as BPC*3), it is also necessary to carry a bitmap for coordinating the allocation of SCellIndex, which is 0011111 in this case.

[0147] Step 2: The second network element sends a second network element addition request confirmation to the first network element: After receiving the SNAddition Request message, the second network element searches for the BC capability parameters, finds the second RAT frequency band that is compatible with the first RAT frequency band 1 (such as the second RAT frequency band 1 in BC#1), and further, finds the BPC (such as BPC*2 and BPC*3) that can be used by the second RAT based on the BPC*3 currently configured for the UE by the first RAT. The second network element decides to select BPC*3 as the baseband capability currently available to the UE on the second network element side, and configures the UE to establish a PSCell and two SCells as service cells on the second network element side.

[0148] According to the available SCellIndex information indicated in the bitmap, the three service cells on the second network element side are configured by the second network element with SCell Index 4 / 5 / 6 respectively. In the SN ADDITIONREQUEST ACKNOWLEDGE message replied to the first network element, in addition to carrying the existing necessary information elements, such as the wireless resource configuration information of the second network element to the UE, it is also necessary to carry the bitmap updated by the second network element, such as 0010001 at this time (indicating that SCellIndex values ​​3 and 7 can still be used by the first network element side).

[0149] Step 3: The first network element saves the updated bitmap for later use, and the first network element performs an RRC connection reconfiguration procedure with the user equipment. Starting from the RRC signaling in step 3, the subsequent signaling process is similar to the existing second network element adding procedure, which will not be repeated here.

[0150] Preferred embodiment 2

[0151] The second network element requests the first network element to use an additional SCellIndex in the form of updating the bitmap, and the first network element agrees. For details about BC and BPC supported by UE, please refer to Figure 2 The hint, Figure 8 is a schematic flow chart of the method provided according to the preferred embodiment 2 of the present invention, such as Figure 8 As shown, the method includes:

[0152] Step 1: When the second network element decides to increase the number of service cells on the second network element side (for example, the second network element decides to change the baseband processing capability on its side from BPC*3 to BPC*4, and both BPCs are compatible with BPC*1 currently used on the first network element side; or the BPC on the second network element side has not changed, but the number of service cells has increased within the limit of the current BPC), it will also require additional SCellIndex (assuming that the SCellIndex occupied by the second network element side that has been indicated to the first network element before this process has not been reserved; or has been reserved, but the additional SCellIndex currently required by the second network element has exceeded the reserved number).

[0153] Based on the bitmap of SCellIndex currently saved on the second network element side (such as 0010001 in Example 1), the second network element selects SCellIndex with a value of 3 as an additional requirement. Therefore, in the interface message sent to the first network element, such as the second network element modification request (SN MODIFICATION REQUIRED) message, it will at least carry the updated bitmap information (0000001), and optionally, it will also carry the target BPC (BPC*4) requested by the second network element.

[0154] Step 2: After receiving the SN MODIFICATION REQUIRED message, the first network element can learn that the second network element has a demand to use the SCellIndex with a value of 3 (for example, by comparing the bitmap originally saved by the first network element with the received bitmap). When the first network element decides to agree to the demand of the second network element (such as the demand does not conflict with the wireless resource configuration on the first network element side), the first network element may carry an indication (indicator) in the interface message (such as the second network element modification confirmation SN MODIFICATION CONFIRM message) replied to the second network element to indicate consent (or no indication, that is, implicit consent).

[0155] Step 3: After confirming that the indicated SCellIndex is allowed to be used, the second network element may generate RRC signaling for adding an SCell (identified by SCellIndex=3 in this example), and send it to the UE via the SRB established with the UE.

[0156] Preferred embodiment 3

[0157] The second network element sends a request to the first network element in the form of the number of additional SCellIndex to be used, and the first network element decides to reject it. For details about BC and BPC supported by UE, please refer to Figure 2 , Fig. 9is a schematic flow chart of the method provided according to the preferred embodiment 3 of the present invention, such as Fig. 9 As shown, the method includes:

[0158] Step 1: The scenario in which the second network element decides to increase the number of serving cells on the second network element side is similar to step 1 of embodiment 2. The SN MODIFICATION REQUIRED message sent to the first network element carries at least the information on the number of SCellIndex additionally required by the second network element (eg, 2).

[0159] Step 2: According to the SN MODIFICATION REQUIRED message, the first network element learns that the second network element needs to use another SCellIndex, and the first network element decides to reject the request. The rejection may be because there is no available SCellIndex at present, and the first network element does not agree to release any SCellIndex on its side. Therefore, in the SN MODIFICATION CONFIRM message replied to the second network element, an indication indicating the rejection of the request needs to be carried.

[0160] Optionally, if the first network element allows the second network element to additionally use a number of SCellIndex values ​​less than the number indicated in the SN MODIFICATIONREQUIRED message, then the SN MODIFICATION CONFIRM message may also carry a bitmap (such as 0000001) marked as 1 at the corresponding bit of the available SCellIndex value.

[0161] Step 3 / 4: The re-coordination procedure for SCellIndex may end until step 2 is completed, but in the case of rejection described in this embodiment, the first or second network element may subsequently make a decision to request the release or switching of the second network element. The signaling process required to be implemented is the same as the prior art and will not be repeated here.

[0162] Obviously, those skilled in the art should understand that the above modules or steps of the present invention can be implemented by a general computing device, they can be concentrated on a single computing device, or distributed on a network composed of multiple computing devices, and optionally, they can be implemented by a program code executable by a computing device, so that they can be stored in a storage device and executed by the computing device, and in some cases, the steps shown or described can be executed in a different order than here, or they can be made into individual integrated circuit modules, or multiple modules or steps therein can be made into a single integrated circuit module for implementation. Thus, the present invention is not limited to any specific combination of hardware and software.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the principle of the present invention shall be included in the protection scope of the present invention.
