Description

 Switching method and source access network node and target access network node

Technical field

 The present invention relates to the field of wireless communication technologies, and in particular, to a handover method, an access network node, and a target access network node. Background technique

 At present, with the rapid development of communication technology, various new access technologies emerge one after another. Since the networks corresponding to various access technologies usually have their own suitable coverage and application scenarios, they are generated by different system applications composed of systems with different access technologies.

 Due to the characteristics of each system, for example, LTE (Long Term Evolution) system has high transmission rate and small coverage, UMTS (Universal Mobile Telecommunications System) has low transmission rate and coverage. Wide range of features, therefore, in practical applications, there is a need for switching between different systems. Different system switching means that the terminal crosses the boundary of the current system and switches the service from the current system to another system. After the system switching is completed, the switched system is used to manage the current service of the terminal.

 For example, when the LTE system coexists with GSM (Global System for Mobile communications), or LTE system and UMTS system, in some scenarios, the terminal needs to switch from one system to another, for example, the terminal is connected. In order to maintain the communication quality of the terminal, the terminal should switch from the GSM system/UMTS system to the LTE system with better signal quality.

In the prior art, when performing handover between different systems, when the target system receives the handover request, as long as it is determined that the target system has the capability of the access terminal, the terminal can be accessed, but there is a rate reduction, A defect that affects the quality of the service. For example, if the handover is initiated by the load, the terminal switches from the LTE system to the UMTS system. If the rate of the UMTS system is lower than the rate of the LTE system, the above method is used, although the terminal can be switched from the LTE system to the LTE system. UMTS system, However, as the service rate is reduced, the quality of the service is affected, and the user experience is reduced. Therefore, when the above method is used to implement the handover between different systems, there is a defect that the service rate is reduced to affect the service quality, thereby affecting the user experience.

 In the embodiment of the present invention, a handover method is proposed, which is: receiving a terminal handover request sent by a source access network node, in order to solve the defect that affects the service quality after the terminal is switched, and the user experience is reduced. And determining, according to the terminal handover request, a rate value after the terminal is switched from the source cell to the target cell; and determining that the estimated rate value after the handover meets the preset condition, sending a terminal handover request response message to the source access network node, so that The source access network node switches the terminal from the source cell to the target cell. Therefore, the solution provided by the embodiment of the present invention ensures that the rate value of the terminal meets the preset condition after being switched to the target system, thereby avoiding the impact on the service quality, and further It also improves the user experience.

 The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings, and the preferred embodiments of the present invention are intended to illustrate and explain the invention, and not to limit the invention, and The embodiments in the application and the features in the embodiments may be combined with each other.

 Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

 Referring to FIG. 1A, an embodiment of the present invention provides a detailed flowchart of the first handover:

 Example 1 (Target System Decision):

 Step 100: Receive a terminal handover request sent by a source access network node.

 Step 110: Estimate a rate value after the terminal switches from the source cell to the target cell according to the terminal handover request.

 Step 120: When it is determined that the estimated rate value after the handover meets the preset condition, send a terminal handover request response message to the source access network node, so that the source access network node switches the terminal from the source cell to the target cell.

 In the implementation of the present invention, the source access network node and the target access network node have various forms, for example, optional, and may belong to any one of the following or any combination of the two:

GSM, CDMA system, TDMA system, WCDMA system, frequency FDMA system, time division synchronous code division multiple access TD-SCDMA (Time Division Synchronized Code Division) Multiple Access; Time Division Synchronous CDMA) System, LTE System.

 In the implementation of the present invention, the source access network node has multiple forms, optionally, a base station or a radio RNC (Radio Network Controller), and the target access network node also has various forms, optionally, The base station or the RNC, where the source access network node and the target access network node are both the base station or the RNC when the terminal is the same system handover, and the source access network node and the target access when the terminal is a different system handover The network nodes are base stations and RNCs.

 In the implementation of the present invention, the terminal handover request may include multiple types of content, for example, including one of a handover indication, a wireless signal measurement result, a rate value required by the terminal after the terminal handover, and a rate value before the terminal handover. Or any combination, of course, in practical applications, may also include other content, no longer here - detailed.

 The switching type of the handover type indication that carries the handover to be performed by the terminal is a load-based handover;

 The wireless signal measurement result is used to indicate that the handover type of the handover to be performed by the terminal is a load-based handover.

 When the handover type of the handover type indication in the handover type indication is a load-based handover, when the terminal handover request is received, it may be determined that the handover type of the handover to be performed is load-based handover, and then executed. The subsequent operations may be performed. Of course, in the actual application, the terminal switching request may not directly carry the load-based handover indication, but may carry the wireless signal measurement result, where the wireless signal measurement result is used to indicate the handover type of the handover to be performed by the terminal. For the load-based handover, when the measurement result of the wireless signal is obtained, it may be determined that the handover type of the handover to be performed is a load-based handover, and then the subsequent operation is performed. The switching indication of the load is used to represent the wireless signal measurement result based on the load switching. At this time, according to any one of the foregoing two methods, the switching type of the handover to be performed is determined to be load-based switching, and then the subsequent execution is performed. Just operate.

 The wireless signal measurement results described above include a variety of information including, for example, the wireless signal quality or signal strength of the terminal in the source system.

The wireless signal measurement result may indicate that the handover type of the handover to be performed by the terminal is load-based. For example, if the radio signal quality of the terminal in the source cell is greater than or equal to -18 db, it is considered that the handover performed by the terminal at this time is a load-based handover. Therefore, when the radio signal measurement result shows that the radio signal quality of the terminal in the source cell is When -2db, it is considered that the handover to be performed by the terminal at this time is a load-based handover.

 Of course, if the radio signal quality of the terminal in the source cell is -26 db, it is considered that the handover performed by the terminal at this time is an overlay-based handover.

 In the embodiment of the present invention, there are multiple types of handovers to be performed, for example, load-based handover, or overlay-based handover, of course, in practical applications, or with the development of communication technologies. There may be other types of switching, which are not repeated here - detailed.

 In the embodiment of the present invention, the rate value may be the number of bits sent to the terminal divided by the length of time used by the terminal, or may be the number of bits sent by the receiving terminal divided by the number sent by the receiving terminal. The length of time used for the above number of bits.

 In the embodiment of the present invention, according to the terminal handover request, there are various ways to estimate the rate value after the terminal switches from the source cell to the target cell, for example:

 Obtaining current load information of the target cell;

 Based on the terminal handover request and the load information, the rate value after the terminal switches from the source cell to the target cell is estimated.

 For example, the downlink power to the idle of the source cell is 20%, the idle downlink channel resource is X, the idle transport block length is Y, the number of idle carriers is 2, the number of idle processes is Τ, based on 20%, X, Υ, Ζ, Τ can estimate the rate value after the terminal switches from the source cell to the target cell, and the specific calculation method is prior art, and is not performed here--details. Of course, there are other implementations that are not described in detail here.

In the embodiment of the present invention, the load information may be in multiple forms, for example, HSPA (High-Speed Packet Access) number information of the target cell, code channel resource usage number information of the target cell, and target cell. The code channel resource usage ratio information, the CE (Channel Element) resource occupancy information of the target cell, the CE resource occupancy ratio information of the target cell, the remaining power value information of the target cell, and the remaining power ratio information of the target cell One or Combination of meanings.

 Of course, the load information may also be other forms of information, which will not be detailed here. Further, in the embodiment of the present invention, before determining that the estimated rate value after the switching meets the preset condition, the following operations are further included:

 Receiving a rate indication message sent by the core network; the rate indication message includes a rate value before the terminal switching and/or a rate value required by the terminal after the terminal is switched;

 The rate value before the terminal is switched is reported to the core network by the source access network node; or it is obtained by the core network;

 The value of the rate required by the terminal after the terminal is switched is set by the source access network node according to the statistics, and is reported to the core network; or the rate value set by the core network before the terminal is switched according to the statistics. of.

 In the embodiment of the present invention, there are various ways to determine that the estimated rate value after the handover meets the preset condition, and optionally, the following manner may be used:

 If the terminal handover request includes the rate value required by the terminal after the terminal is switched, determining that the estimated rate value after the handover is greater than or equal to the rate value required by the terminal after the terminal handover;

 If the terminal handover request includes the rate value before the terminal handover, it is determined that the estimated handover rate value is greater than or equal to the rate value before the terminal handover.

 That is, in the embodiment of the present invention, the preset condition may be in various forms, for example, the rate value before the terminal is switched, or the rate value required by the terminal after the terminal is switched. It is larger than the rate before the terminal is switched, and can also be smaller than the rate before the terminal is switched.

 In the implementation of the present invention, the terminal handover request includes the service type information of the terminal in the source system and/or the radio resource configuration information of the terminal in the source system; wherein, the service type information of the terminal in the source system and/or the radio resource of the terminal in the source system Configuration information can be used to estimate the rate value before the terminal is switched.

 At this time, when it is determined that the estimated rate value after the switching is greater than or equal to the preset threshold, the following manner may be used:

Estimating the rate value before the terminal is switched according to the service type information of the terminal in the source system and/or the radio resource configuration information of the terminal in the source system; It is determined that the estimated rate value after the handover is greater than or equal to the rate value before the terminal handover. That is to say, the rate value before the terminal handover may be estimated according to the service type information of the terminal in the source system and/or the radio resource configuration information of the terminal in the source system.

 In the embodiment of the present invention, the method for obtaining the rate value before the handover of the terminal is used. For example, the rate value before the terminal handover may be carried in the terminal handover request, and when the terminal handover request is received, the rate value before the terminal handover is obtained. And the obtained rate value before the terminal switching can be used as the preset condition value.

 Certainly, the rate value before the terminal handover may be obtained by using other methods. For example, the terminal handover request includes the service type information of the terminal in the source system and/or the radio resource configuration information of the terminal in the source system.

 At this time, when obtaining the rate value before the terminal handover, it may be:

 The rate value before the terminal handover is estimated according to the service type information of the terminal in the source system and/or the wireless channel configuration information of the terminal in the source system.

 The service type information refers to a specific application, and may be (FTP (File Transfer Protocol) service, or may be, VIDEO (video) service, or may be a web service, a game service, etc., of course, May be other business, no longer here - detailed.

 The radio resource configuration information may refer to the configuration of the terminal bandwidth, the configuration of the number of carriers, the configuration of the physical channel, the configuration of the transmission rate channel, and the like, and may be other configuration information, which will not be described in detail herein.

 In the embodiment of the present invention, the rate value before the terminal is switched may be the rate value of the terminal at a certain moment of the source system, or the average rate value of the terminal in a certain period of the source system, or the average rate. The value obtained by multiplying the value by the preset coefficient, where the preset coefficient has a value range of [0, 1].

 Certainly, the terminal handover request may not carry a specific rate value, but carries a segment of the rate value for characterizing the high, medium, and low rates, for example, carrying an interval segment for characterizing the high rate.

(100Mbps, +∞), at this time, when the target access network node receives the interval, it can determine that the estimated rate value is greater than 100Mbps. Of course, in practical applications, there are other ways, and no longer here - detailed. In the embodiment of the present invention, the rate value of the terminal before the handover is transmitted in multiple manners, and the method may be performed by using a standard procedure. For example, the terminal handover request sent by the source access network node carries the rate value before the handover of the terminal to the core network. Sending to the target access network node via the core network; or, the source access network node sends the rate value before the terminal handover through the RAN (Radio Access Network) process of the RAN (Radio Access Network) To the target access network node, or the source access network node sends the rate value before the terminal handover to the target access network node through a private process.

 The foregoing process is to determine the case that the estimated rate value after the handover meets the preset condition. In the actual application, the method further includes determining that the estimated rate value after the handover does not meet the preset condition. After determining that the estimated rate value after the handover does not meet the preset condition, the terminal may send a reject access message, where the reject access message is used to reject the terminal access terminal. That is to say, when it is determined that the estimated rate value after the handover does not meet the preset condition, the source access network node sends a reject access message and denies the terminal access.

 In the embodiment of the present invention, optionally, the denying the access message includes the reason for denying the terminal access, such as the reason that the preset condition cannot be met.

 In the embodiment of the present invention, in order to improve the access success rate, the terminal handover request includes the identifier information of the target cell;

 At this time, when the terminal is switched from the source cell to the target cell, it is specifically:

 If the load capacity of the target cell corresponding to the identifier information is smaller than the load preset value, the terminal is switched from the source cell in the source system to the target cell; or

 If the load capacity of the target cell corresponding to the identifier information is greater than or equal to the load preset value, determine other cells that are in the target system and are adjacent to the source cell;

 The cells corresponding to the load preset value are selected from other cells;

 The terminal is switched from the source cell to the selected one of the cells. Of course, in order to ensure the quality of the terminal, the signal quality of the cell is greater than the signal quality preset threshold.

In the embodiment of the present invention, the terminal handover request may further include an enhanced feature capability letter supported by the terminal. The information about the enhanced feature capability supported by the terminal includes the terminal supporting the uplink multi-carrier configuration information, the terminal supporting the downlink multi-carrier configuration information, the terminal supporting the MIMO (Multple Input Multiple Output) configuration information, and the terminal supporting the multi-flow configuration. The information and the terminal support 64 QAM (Quadature Amplitude Modulation) configuration information, the terminal supports CLTD (Closed Loop Transmit Diversity) information, and the terminal supports one or any combination of open loop transmit diversity information.

 After determining the enhanced feature capability supported by the terminal, the enhanced wireless channel resource information is configured for the terminal according to the application scenario.

 In order to improve the rate after the terminal is switched to the target system, in the embodiment of the present invention, before the terminal is switched from the source cell to the target cell, the method further includes:

 The enhanced wireless channel resource information is configured for the terminal according to the enhanced characteristic capability information supported by the terminal.

 For example, when the terminal supports the uplink multi-carrier DC (Double Cell)-HSUPA (High Speed Uplink Packet Access), the target access network node configures the enhanced wireless channel resource information for the terminal. The terminal may be allocated uplink bus channel resource information of the secondary carrier, and the information is included in the handover command.

 In the embodiment of the present invention, the terminal switching request may include the enhanced characteristic capability information supported by the terminal. However, when the enhanced characteristic capability information supported by the terminal is obtained, the enhanced wireless channel resource may be configured for the terminal according to the enhanced characteristic capability information supported by the terminal. The information may also not be configured with enhanced wireless channel resource information for the terminal.

 In the embodiment of the present invention, there are various conditions for triggering the configuration of the enhanced radio channel resource information for the terminal. For example, the terminal handover request carries an indication message, where the indication message is used to indicate that the target access network node configures the enhanced radio channel resource for the terminal. Information, at this time, according to the enhanced characteristic capability information supported by the terminal, the enhanced wireless channel resource information is configured for the terminal, or if the estimated rate value after the handover does not meet the preset condition, the capability information according to the enhanced feature supported by the terminal is The terminal configures enhanced wireless channel resource information, which is used to improve the rate after the terminal switches to the target system.

Alternatively, it may be that even if it is determined that the estimated rate value after the switching meets the preset condition, In order to further improve the rate value after the terminal is switched to the target system, the enhanced wireless channel resource information may be configured for the terminal according to the enhanced characteristic capability information supported by the terminal, thereby improving the rate after the terminal switches to the target system.

 Certainly, the indication message carried in the terminal handover request is obtained, and the indication message is used to indicate that the target access network node configures the enhanced wireless channel resource information for the terminal, and the resource information of the target system may be further combined with the enhanced information supported by the terminal. Whether the capability information is to configure enhanced wireless channel resource information for the terminal.

 In the implementation of the present invention, the rate value of the terminal in the source cell or the estimated rate value in the target cell may be an uplink rate value or a downlink rate value.

 In an actual application, the type of the handover to be performed may also be an overlay-based handover. At this time, after receiving the terminal handover request sent by the source access network node, it is not necessary to estimate the rate value after the terminal switches from the source cell to the target cell. The terminal handover request response message is directly sent to the source access network node, and the terminal is handed over from the source cell to the target cell.

 The sending of the terminal handover request response message to the source access network node is not described herein, but the target access network node does not make any judgment, but also determines whether the target cell still has the capability of accommodating the terminal, and also has the capacity to determine the target cell. When the capability of the terminal is, the terminal handover request response message is sent to the source access network node to switch the terminal from the source cell to the target cell. Since this is a prior art, a well-known technology, therefore, it is not performed here--details.

 In the embodiment of the present invention, when determining the handover type of the handover to be performed, the terminal switching request may include a handover indication or a wireless signal measurement result to determine whether the handover type indication carries the handover type of the handover to be performed. If the load is switched, it is considered to be a load-based handover. If it is not carried, it is considered to be an overlay-based handover, or the handover type of the handover that directly carries the terminal to be performed is an overlay-based handover; or, the wireless signal is viewed. Whether the measurement result is a handover type for indicating a handover to be performed by the terminal is a load-based handover, and if so, it is considered to be a load-based handover; otherwise, it is considered to be an overlay-based handover, and of course, other judgment methods are required. This will not be detailed.

That is, the terminal handover request includes an overlay-based handover indication or is used to characterize the overlay-based When the handover wireless signal measurement result is received, after receiving the terminal handover request, it is not necessary to estimate the rate value after the terminal switches from the source cell to the target cell, and directly send a terminal handover request response message to the source access network node, and the terminal is sourced from the source. The cell switches to the target cell.

 In practical applications, in some scenarios, the quality of the wireless channel is poor. After the terminal configures the enhanced wireless channel resource information, the source access network node sends the handover command to the terminal to carry the wireless channel resource information configured for the terminal. In this way, the information sent by the source access network node is sent to the source access network node. Before the response message, the method further includes: receiving an indication message sent by the source access network node, where the indication message is used to indicate that the target access network node prohibits configuring the enhanced radio resource information for the terminal;

 At this time, when the terminal is switched from the source cell to the target cell, the following manner may be adopted: The terminal that does not configure the enhanced radio resource information is switched from the source cell to the target cell.

 The above description is that the indication message clearly indicates that the target access network node prohibits the configuration of the enhanced radio resource information for the terminal. Of course, in the actual application, when the source access network node is not received, the enhanced radio resource information is allowed to be configured for the terminal. In this case, the target access network node may not configure the terminal with the enhanced radio resource information indication message. In this case, when the terminal is switched from the source cell to the target cell, the following manner may be used:

 The terminal that does not configure the enhanced radio resource information is handed over from the source cell to the target cell.

 In the embodiment of the present invention, the enhanced radio channel resource information includes multiple types of information, and optionally, any one of the following or any combination of the following may be included:

 Uplink multi-carrier configuration information, downlink multi-carrier configuration information, MIMO configuration information, multi-stream configuration information, 64 QAM configuration information, CLTD information, and open-loop transmit diversity information.

 In the embodiment of the present invention, in order to improve the robustness of the link quality of the terminal to the target cell, the target system may select multiple cell configuration macrodiversity according to the radio signal measurement result, and notify the terminal to perform an immediate macro in the handover command. Diversity, that is, the terminal is connected to each cell included in the macro diversity.

The above process sends a terminal handover request response message to the source access network node, and the terminal is small from the source. Before the area is switched to the target cell, it is also determined whether the target cell has the capability of accommodating the terminal. When the target cell has the capability of accommodating the terminal, the terminal accesses the target cell. However, this is a prior art, and therefore, No longer - detail.

 Referring to FIG. 1B, the embodiment of the present invention provides a second detailed flowchart of switching:

 Example 2 (Target System Decision):

 Step 1000: Send a terminal handover request to the target access network node.

 Step 1100: Receive a terminal handover request response message sent by the target access network node, and switch the terminal from the source cell to the target cell. The terminal handover request response message is that the target access network node determines that the terminal is estimated according to the terminal handover request. Sent when the rate value after the source cell switches to the target cell meets the preset condition.

 In the implementation of the present invention, the source access network node and the target access network node have various forms, for example, optional, and may belong to any one of the following or any combination of the two:

 GSM, CDMA system, TDMA system, WCDMA system, FDMA system, TD-SCDMA system, LTE system.

 In the implementation of the present invention, the source access network node has multiple forms, optionally, a base station or a wireless RNC, and the target access network node also has various forms, optionally, a base station or an RNC, where, when the terminal When the system is switched, the source access network node and the target access network node are both the base station or the RNC. When the terminal is an inter-system handover, the source access network node and the target access network node are the base station and the RNC.

 In the implementation of the present invention, the terminal handover request may include multiple types of content, for example, including one of a handover indication, a wireless signal measurement result, a rate value required by the terminal after the terminal handover, and a rate value before the terminal handover. Or any combination, of course, in practical applications, may also include other content, no longer here - detailed.

 The switching type of the handover type indication that carries the handover to be performed by the terminal is a load-based handover;

The wireless signal measurement result is used to indicate that the handover type of the handover to be performed by the terminal is load-based handover. When the handover type of the handover type indication in the handover type indication is a load-based handover, when the terminal handover request is received, it may be determined that the handover type of the handover to be performed is load-based handover, and then executed. The subsequent operations may be performed. Of course, in the actual application, the terminal switching request may not directly carry the load-based handover indication, but may carry the wireless signal measurement result, where the wireless signal measurement result is used to indicate the handover type of the handover to be performed by the terminal. For the load-based handover, when the measurement result of the wireless signal is obtained, it may be determined that the handover type of the handover to be performed is a load-based handover, and then the subsequent operation is performed. The switching indication of the load is used to represent the wireless signal measurement result based on the load switching. At this time, according to any one of the foregoing two methods, the switching type of the handover to be performed is determined to be load-based switching, and then the subsequent execution is performed. Just operate.

 The wireless signal measurement results described above include a variety of information including, for example, the wireless signal quality or signal strength of the terminal in the source system.

 The wireless signal measurement result may indicate that the handover type of the handover to be performed by the terminal is a load-based handover. For example, if the wireless signal quality of the terminal in the source cell is greater than or equal to -18 db, it is considered that the handover performed by the terminal at this time is a load-based handover. Therefore, when the wireless signal quality of the terminal in the wireless signal measurement result is -2 db, it is considered that the handover to be performed by the terminal is a load-based handover.

 The terminal handover request includes service type information of the terminal in the source cell and/or wireless resource configuration information of the terminal in the source cell;

 The service type information of the terminal in the source cell and/or the radio resource configuration information of the terminal in the source cell are used by the target access network node to estimate the rate value before the terminal handover.

 The foregoing process describes the process in which the estimated rate value of the terminal after the cell is switched from the source cell to the target cell meets the preset condition. In actual applications, the estimated rate value of the terminal after switching from the source cell to the target cell may not be The preset condition is met. At this time, the reject access message sent by the target access network node is received, and the terminal access is denied.

The reject access message is sent when the target access network node determines that the estimated rate value after the handover does not meet the preset condition. Optionally, rejecting the access message includes rejecting the terminal access.

 In practical applications, in some scenarios, the quality of the wireless channel is poor. After the terminal configures the enhanced wireless channel resource information, the source access network node sends the handover command to the terminal to carry the wireless channel resource information configured for the terminal. In this way, the information transmitted is large, the probability of retransmission due to segmentation is high, and the handover failure may occur. Therefore, in the implementation of the present invention, in order to improve the handover success rate of the terminal, further, the receiving target access network node sends Before the terminal switches the request response message, the following operations are also included:

 And sending an indication message to the target access network node, where the indication message is used to indicate that the target access network node prohibits configuring the enhanced radio resource information for the terminal;

 At this time, the terminal is switched from the source cell to the target cell, which may be:

 The terminal that does not configure the enhanced radio resource information is handed over from the source cell to the target cell.

 The above-mentioned fascination is that the indication message clearly indicates that the target access network node prohibits the configuration of the enhanced radio resource information for the terminal. Of course, in the actual application, when the target access network node is not sent, the enhanced radio resource information is allowed to be configured for the terminal. In this case, the target access network node may not configure the terminal with the enhanced radio resource information indication message. In this case, when the terminal is switched from the source cell to the target cell, the following manner may be used:

 The terminal that does not configure the enhanced radio resource information is handed over from the source cell to the target cell.

 In the embodiment of the present invention, the enhanced radio resource information has multiple forms, for example, including any one of the following or any combination of the following: uplink multi-carrier configuration information, downlink multi-carrier configuration information,

ΜΙΜΟ Configuration information, multi-flow configuration information, 64 QAM configuration information, CLTD information, open-loop transmit diversity information. Of course, in actual applications, other information may also be included, which is not repeated here--details.

 At this time, when the terminal is switched from the source cell to the target cell, the optional one may be:

 The terminal that does not configure the enhanced radio resource information is handed over from the source cell to the target cell.

 The above-mentioned fascination is that the indication message clearly indicates that the target access network node prohibits the configuration of the enhanced radio resource information for the terminal. Of course, in the actual application, when the target access network node is not sent, the enhanced radio resource information is allowed to be configured for the terminal. In this case, the target access network node may not configure the terminal with the enhanced radio resource information indication message. In this case, when the terminal is switched from the source cell to the target cell, the following manner may be used:
