DETAILED DESCRIPTION OF THE EMBODIMENTS In order to make the objects, technical solutions, and advantages of the present invention more comprehensible, the technical solutions provided by the present invention are further described in detail below with reference to the accompanying drawings.

1 shows, by way of example, a schematic diagram of a system 100 that includes a terminal 110 and a network side device 120.

In system 100, terminal 110 is a terminal in connected mode, and terminal 110 moves from a cell located in the GERAN network to a CSG cell located in the UTRAN network or E-UTRAN network. In this process, if the terminal 110 finds that there is a CSG cell that allows the terminal 110 to access, the terminal 110 notifies the network side device 120. To this end, the terminal 110 can perform the CSG cell in the UTRAN network or the E-UTRAN network. The CSG cell is measured and reported to the network side device 120, and the report information may further include a measured value result of the CSG cell.

A home base station in an E-UTRAN network may be referred to as a Home eNodeB, and a home base station in a UTRAN network may be referred to as a Home NodeB, whether it is an E-UTRAN network or a home base station in a UTRAN network. They can be deployed in places such as homes or enterprises. The cells of these home base stations can also be set to closed mode and mixed mode, and their cells can be called E-UTRAN CSG cells or UTRAN CSG cells, and E-UTRAN. Hybrid cell or UTRAN Hybrid cell. In the embodiment of the present invention, the home base station cell may be at least one of a home base station cell in the E-UTRAN network and a home base station in the UTRAN network, and the CSG cell may include a CSG cell in the home base station cell and At least one of a hybrid cell (Hybrid Cell).

In system 100, network side device 120 can be a base station subsystem (Base Station

Subsystem, BSS), one of the Radio Network System (RNS), the evolved NodeB (eNodeB), and the home base station.

When the terminal sends a measurement report of the CSG cell that meets the measurement reporting condition to the network side, the terminal selects one of the following in the measurement report: carrying the routing parameter information of the CSG cell, or carrying the frequency and interference of the CSG cell. The code information includes indicating the corresponding frequency point information and the scrambling code information by means of a frequency point index or a cell index, where the scrambling code includes a Primary Scrambling Code (PSC) for the CSG cell in the UTRAN network and for the E- Physical layer Cell ID (PCI) of the CSG cell in the UTRAN network. It can be found that: when the terminal 110 does not report the parameters for performing PS handover to the CSG cell, such as routing parameters, but reports the frequency and scrambling code information of the CSG cell to the network side device 120, due to the frequency and interference of the CSG cell. The code information is variable. Therefore, even if the terminal 110 reports the frequency and scrambling code of the CSG cell, the network side device 120 cannot uniquely determine a CSG cell by using the information reported by the terminal 110. The inventor of the present invention has found that, in order to notify the network side device 120 that the CSG cell that is allowed to access is detected, if the terminal 110 does not report the routing parameter of the CSG cell to the network side device 120, the terminal 110 reports the frequency and scrambling code of the CSG cell. Information is not necessary.

Accordingly, an embodiment of the present invention provides a method of indicating a CSG cell by way of example. As shown in Figure 2, the method includes:

The terminal 110 in the connected mode sends a first message to the network side device 120, where the first message includes first indication information, where the first indication information is used to: indicate whether there is a CSG cell that allows the terminal 110 to access, And indicating the routing parameter information that does not carry the CSG cell in the first message, and the frequency point information and the scrambling code information indicating that the CSG cell is not carried in the first message. Interest.

The CSG cell may include at least one of a CSG cell in the E-UTRAN network and a CSG cell in the UTRAN network.

The connected mode terminal 110 may be a terminal that is performing data services, voice services, or simultaneous data and voice services, and may be, for example, a terminal in a packet transmission mode, a dedicated mode, or a dual transmission mode.

The following is an example to illustrate that the first indication information indicates that the first message does not carry the

The case of routing parameter information of a CSG cell.

For example, when both the terminal 110 and the network side device 120 support a packet switching (PS) switching operation, the network side device 120 notifies the terminal 110 that the network side device 120 supports the PS handover, but the network side device 120 has the PS. The switching capability does not necessarily perform the PS handover. In this case, the terminal 110 may not report the routing parameter information of the CSG cell to the network side device 120.

For example, when one of the terminal 110 and the network side device 120 does not support the PS handover operation, the terminal 110 may not carry the routing parameter in the measurement report sent to the network side device 120.

In this embodiment, the terminal in the connected mode detects the CSG cell that is allowed to access, and the terminal sends the first message to the network side device, where the terminal generates the first message that is reported to the network side device. An indication information indicates that the network side device has a CSG cell that allows the terminal to access, and the first message does not carry the routing parameter information of the CSG cell, and does not carry the frequency information of the CSG cell. 4 Yu code information. Therefore, when the terminal does not use the CSG cell routing parameter information to indicate the CSG cell that is allowed to access, the terminal can save the unnecessary frequency information and the scrambling code of the CSG cell in the first message sent to the network side device. The control message bit resource consumption required for the information. The terminal can implement the function of notifying the network-side candidate CSG cell with fewer bits, and saves valuable air interface resources compared with the frequency information and the scrambling code of the CSG cell or the information of other CSG cells. At the same time, it further saves the setting of routing parameter information or frequency point and scrambling code information in the first message. Time, the terminal can notify the network side device more quickly whether there is access to the terminal.

The CSG cell, and the network side device can also parse the first message to obtain the notification information sent by the terminal, and correspondingly, if the network determines that the target cell to be handed over is a macro cell, the bit resource in the transmission process can be saved. If the network determines that the target cell to be handed over is a CSG cell, the network side can still request the terminal to report other information of the CSG cell without affecting subsequent PS handover.

Another method of indicating a CSG cell is provided by way of example in one embodiment of the invention. As shown in Figure 3, the method includes:

The terminal 110 in the connected mode sends a first message to the network side device 120, where the first message includes first indication information, where the first indication information is used to: indicate whether there is a CSG cell that allows the terminal 110 to access, and the indication The first message does not carry the routing parameter information of the CSG cell, and the frequency point information and the scrambling code information indicating that the CSG cell is not carried in the first message.

The first indication information in the first message is not limited to indicating one or more CSG cells that allow terminal 110 to access.

The first message may be one of a packet measurement report PMR message, a packet enhanced measurement report PEMR message, and a packet cell change notification PCCN message.

The size of the bit area occupied by the first indication information in the first message may be one bit, two bits or more.

Further, when the size of the bit area occupied by the first indication information in the first message is two bits or more, the first indication information may further indicate: whether there is a location that allows the terminal to access Determining at least one of a CSG cell in the UTRAN network and a CSG cell in the E-UTRAN network that allows the terminal to access.

Further, before the terminal 110 sends the first message to the network side device 120, the terminal 110 may further include: the terminal 110 receiving, by the network side device 120, whether the indication information for the CSG cell packet switching PS handover parameter is reported. The indication information may be carried by a message such as a packet measurement command message, a packet cell change command message, or a system message. When the terminal 110 receives the network side When the device 120 sends the indication information for the CSG cell PS handover parameter, the terminal 110 sends the first message to the network side device 120.

320. The network side device 120 receives the first message, where the first message includes first indication information. The first indication information is used to indicate whether there is a CSG cell that allows the terminal 110 to access. According to the indication, the network side device 120 may determine whether there is a CSG cell that allows the terminal 110 to access, and the CSG cell may be a CSG cell. It can also be multiple CSG cells.

The network side device 120 sends a second message according to the first message, where the second message includes indication information indicating whether the terminal reports a handover parameter for performing CSG cell PS handover. When the first indication information indicates that there is a CSG cell that allows the terminal 110 to access, the network side device 120 transmits a second message to the terminal 120 according to the indication. The second message may be one of a packet cell change continuation message and a packet cell change command message bearer. The network side device 120 sends the indication information indicating whether the terminal reselects to the CSG cell to the terminal by using a Packet Cell Change Continue (PCCC) message or a Packet Cell Change Order (PCCO) message. 110. The indication information also indicates that the terminal 110 does not report the handover parameter used for performing the CSG cell PS handover to the network side device 120.

In this embodiment, the terminal in the connected mode sends a first message to the network side device to indicate whether there is a CSG cell that allows the terminal 110 to access, and indicates that the first message does not carry the routing parameter information of the CSG cell, and the indication The message does not carry the frequency information and the scrambling code information of the CSG cell, and can save unnecessary control message bit resources required for carrying the frequency information and the scrambling information of the CSG cell in the first message sent to the network side device. Consumption. The terminal can implement the function of notifying the network-side candidate CSG cell with fewer bits. Compared with reporting the frequency and scrambling code of the CSG cell or reporting the information of other CSG cells, the terminal can save valuable air interface resources. At the same time, the time for setting the routing parameter information or the frequency point and the scrambling code information in the first message is further saved, and the terminal can notify the network side device whether the device exists or not. The CSG cell that the terminal accesses, and the network side device can also parse the first message to obtain the notification information sent by the terminal, and then instruct the terminal to reselect to the CSG cell. Therefore, when the network side determines that the target cell to be subsequently switched by the terminal is a macro cell, or instructs the terminal to perform reselection to the CSG cell or the macro cell, bit resources can also be saved.

Yet another embodiment of the present invention provides, by way of example, a method of indicating a CSG cell. As shown in Figure 4, the method includes:

When the second message includes the indication information indicating that the terminal is to perform the handover parameter for performing the CSG cell PS handover, the indication information that the indication terminal 110 reports the handover parameter for performing the CSG cell PS handover is actually indicated at the same time. Terminal 110 needs to perform packet switched PS handover.

The terminal 110 receives the second message.

The terminal 110 sends a third message to the network side device 120, when the second message includes the indication information indicating that the terminal is to report the handover parameter for performing the CSG cell PS handover.

The terminal 110 learns that the handover parameter for performing CSG cell PS handover needs to be reported to the network side device 120 according to the indication information indicating the handover parameter for the CSG cell PS handover in the second message, and correspondingly, the terminal 110 sends the third message. To the network side device 120.

The third message may include one of frequency point information of the target CSG cell to be handed over by the terminal 110, scrambling code information of the target CSG cell, routing parameter information of the target CSG cell, and a CSG identity of the CSG target cell.

The third message may be one of a packet measurement report message, a packet enhanced measurement report message, and a packet cell change notification message.

However, when the second message includes indication information indicating that the terminal does not report the handover parameter for performing CSG cell PS switching, the terminal 110 may not send the third message to the network side device 120, that is, the terminal 110 does not execute 450.

460. According to the third message sent by the terminal 110, the network side device 120 sends a PS handover command to the terminal 110, instructing the terminal 110 to perform PS handover, and handover to the target CSG cell.

In this embodiment, the terminal in the connected mode sends a first message to the network side device to indicate whether there is a CSG cell that allows the terminal 110 to access, and indicates that the first message does not carry the routing parameter information of the CSG cell, and the indication A message does not carry the frequency information and the scrambling code information of the CSG cell, and can save unnecessary carrying in the first message sent to the network side device.

The terminal can implement the function of notifying the network-side candidate CSG cell with fewer bits, and saves the air interface resource compared to the frequency of the CSG cell and the scrambling code or the information of other CSG cells. At the same time, the time for setting the routing parameter information or the frequency point and the scrambling code information in the first message is further saved, and the terminal can notify the network side device more quickly whether there is a CSG cell that allows the terminal to access. The network side device can also parse the first message more quickly to obtain the terminal. Sending the notification information, and then instructing the terminal to report the frequency point information of the target CSG cell to which the handover is performed, the scrambling code information of the target CSG cell, the routing parameter information of the target CSG cell, and one of the CSG identifiers of the CSG target cell.
