Example 1

Referring to FIG. 3, this embodiment provides a method for transmitting neighboring area information of a multi-site common cell, including:

301: The base station acquires first configuration information.

The first configuration information includes: a neighboring area information that allows a specified location group to transmit a specified location group through a broadcast channel in a multi-site common cell, and content that includes neighboring area information of the specified location group by using a broadcast channel;

Wherein, the multi-site common cell is composed of a plurality of location groups, and the designated location group is part of the multiple location groups; The content included in the neighboring area information of the specified location group by the broadcast channel may be presented in the form of a neighbor list.

302: The base station sends, according to the first configuration information, the neighboring cell information to the idle terminal in the specified location group by using a broadcast channel, where the neighboring cell information is used by the idle terminal to perform neighboring cell measurement.

In this embodiment, the specified location group is a partial location group in the multi-site common cell, and is preferably an edge location group of the multi-site common cell. For example, multiple location groups in a multi-site common cell are chained, and the specified location group may be a location group at both ends of the chain.

Optionally, the acquiring, by the base station, the first configuration information may include: receiving, by the base station, the first configuration information sent by the base station control node; or configuring the first configuration information locally, where the base station may be: Obtaining first configuration information, where the system configuration information can be used for data configuration of the base station.

Optionally, the method may further include: acquiring, by the base station, second configuration information, where the second configuration information includes: not allowing other location groups other than the specified location group to send neighboring area information of the other location group through a broadcast channel; The base station sends, according to the second configuration information, a system message that does not include neighboring cell information to the idle terminal in the other location group through the broadcast channel.

Optionally, the method may further include: the base station transmitting, to the terminal in the service state, the neighboring area information of the traffic channel for all the location groups of the multi-site common cell by using the traffic channel: where the neighboring area information for the traffic channel refers to The neighboring area information that can be sent through the service channel; the base station receives the measurement report reported by the terminal in the service state according to the neighboring area information of all the location groups, and the measurement report includes the location group and the neighbor currently in the service state. The base station may send the measurement report to the base station control node, where the base station control node performs a handover decision according to the measurement report; or the base station may also perform a handover decision according to the measurement report (for example, in a flat architecture network system) .

Wherein, the handover decision is performed according to the measurement report, including:

It is determined whether the location group that the terminal in the service state is currently in the specified location group, and if yes, determines whether the terminal in the service state is triggered to switch to the neighboring cell according to the neighboring area measurement result. This step can be performed by the base station control node. In an LTE (Long Term Evolution) system, it can also be executed by an eNodeB (evolved Node base station).

The foregoing method provided in this embodiment can be applied to a 2G system, a 3G system, and an LTE system. The base station can be specifically a BTS (Base Transceiver Station), an odeB (Node base station, a base station). ) or eNodeB. The base station control node may be specifically a BSC (Base Station Controller) or an RC (Radio Network Controller). Specifically, the broadcast channel may be a BCCH (Broadcast Control Channel) or a BCH (Broadcast Channel). The traffic channel refers to a TCH (Traffic Channel), which has not been used in this embodiment of the present invention. More explanation.

Further, the neighboring cells involved in this embodiment may be configured for a location group, instead of being configured for a multi-site common cell (targeting the whole of the multi-site common cell), and for broadcasting channels and services. The channels are configured separately. The content of the neighboring area information that is sent by the specified location group through the broadcast channel may be a neighboring area list of the specified location group, where the neighboring area in the neighboring area list is configured by using the specified location group as the configuration object. Neighborhood. Taking the scenario of FIG. 1 as an example (a multi-site common cell includes four location groups), in the prior art, although the four location groups are not physically located, the location groups share the same neighboring cells. However, in the technical solution provided by the embodiment of the present invention, the neighboring zone configuration may be performed in a location group. For example, location group 1 at the edge may configure neighbor 1 for the broadcast channel and location group 4 at the edge may configure neighbor 2 for the broadcast channel. The intermediate location groups 2 and 3 can simultaneously configure neighbors 2 and 3 for the broadcast channel. Of course, the above configuration is just an example.

The foregoing method provided in this embodiment, in a multi-site common cell scenario, sends neighboring cell information to a specified location group through a broadcast channel, which can meet the mobility management requirements of the terminal in a specific location group, and enhance the user experience. Example 2

Referring to FIG. 4, this embodiment provides a method for transmitting neighboring area information of a multi-site common cell, and the 2G system is taken as an example for description, including:

401: The BSC configures the first configuration information for the multi-site common cell, and sends the first configuration information to the base station. The first configuration information includes: allowing the specified location group to send the neighbor information through the BCCH in the multi-site common cell. And content included in the neighboring area information of the specified location group for the broadcast channel (ie, transmitted through the broadcast channel); the designated location group is a part of the plurality of location groups of the multi-site common cell.

The content included in the neighbor information may be presented in the form of a neighbor list.

The base station receives the first configuration information from the BSC, and broadcasts the first system message on the BCCH of the specified location group according to the first configuration information, and notifies the neighboring cell information of the specified location group of the idle terminal in the specified location group.

403: The idle terminal in the specified location group receives the first system message, performs measurement on the corresponding neighboring cell according to the neighboring cell information, and determines whether to reselect the neighboring cell according to the result of the measurement.

For example, if the wireless signal strength of the neighboring cell measured by the idle terminal is greater than the wireless signal strength of the current multi-site common cell and exceeds a preset threshold, the idle terminal is initiated to reselect to the tested neighboring cell.

Optionally, the foregoing method may further include:

404: The BSC configures the second configuration information for the multi-site common cell, and sends the second configuration information to the base station. The second configuration information includes: the location group other than the specified location group is not allowed in the multi-site common cell. Sending the neighboring area information by using the BCCH; after receiving the second configuration information, the base station broadcasts the second system message on the BCCH of the other location group according to the second configuration information, where the second system message does not include the neighboring area information, thereby making the monitoring After receiving the second system message, the idle terminal of the BCCH does not need to initiate measurement of the neighboring cell, thereby avoiding reselection to the neighboring cell.

For example, if the specified location group is an edge location group and the other location group is an internal location group, the neighboring zone information of the broadcast edge location group may cause the idle terminal in the edge location group to be reselected to the neighboring cell, and the neighboring zone of the internal location group is not broadcasted. The information can avoid the re-election of the idle terminal in the internal location group to the neighboring cell, and improve the ability of the terminal to reside in the internal location group, so that the idle terminals of the location group with different physical locations in the multi-site common cell have different re-election capabilities, and improve The re-election effect of the cell.

Optionally, the foregoing method may further include:

405: The BSC configures the third configuration information for the multi-site common cell and sends the third configuration information to the base station, where the third configuration information includes: allowing all the location groups in the multi-site common cell to send the neighboring areas of the all location groups by using the TCH. Information, and neighboring area information of all the location groups for the traffic channel (that is, transmitted through the traffic channel); after receiving the third configuration information, the base station sends the third system message to the terminal in the service state on the TCH according to the third configuration information, The third system message includes the neighboring area information of all the location groups; after receiving the third system message, the terminal in the multi-site common cell receives the third system message, and according to the neighboring area information in the third system message, the corresponding neighbor The area performs measurement, and reports the measurement report to the base station. The measurement report includes the location group and the neighboring area measurement result currently in the service state. After receiving the measurement report, the base station sends the measurement report to the BSC. After receiving the measurement report, the BSC receives the measurement report. Determining, according to the location group information therein, whether the location group currently in the service state is in the above specified location group Counter group (group such as an edge position), if so, to determine whether the measurement terminal in a traffic state of the trigger switch according to the neighboring neighbor. For example, if the terminal in the call is currently in the specified location group and the measured wireless signal strength of the neighboring cell is greater than the wireless signal strength of the multi-site common cell, the terminal is triggered to switch to the tested neighboring cell.

Of course, the above method can also be applied to 3G systems, the difference is: BSC is replaced by RNC, BCCH is replaced by

BCH, the rest of the process and features are similar, so I won't go into details. In addition, the foregoing method may be further applied to the LTE system, where the process in the LTE system is different from the foregoing method: configuring at least one of the first configuration information, the second configuration information, and the third configuration information locally in the eNobeB, and sending the corresponding The system message is sent to the terminal, and after receiving the measurement report of the terminal, the handover decision is performed according to the measurement report. The specific procedures and features are similar to those in the foregoing method, and therefore are not described herein.

Generally, there are usually two types of system messages sent by a base station to carry neighboring cell information, one is broadcast on the BCCH or BCH, and the other is sent on the TCH. The terminal in the idle state listens to the broadcast message on the BCCH or the BCH, and the terminal in the service state listens to the system message on the TCH. In this embodiment, the first system message or the second system message broadcasted on the BCCH or the BCH includes but is not limited to: system message 2, system message 2bis, system message 2ter, and the like. The third system message sent on the TCH includes but is not limited to: system message 5, system message 5bis, system message 5ter, and the like. The timing of sending the above system messages is detailed in 3GPP 45.002 protocol, and the coding of each system message is detailed. 3GPP 44018 protocol, not described here.

Further, the neighboring area involved in this embodiment may be configured for the overall configuration of the multi-site common cell, or may be configured for the location group, and the neighboring area information of the specified location group sent by the broadcast channel is included. The content includes: A list of neighbors for the specified location group. For example, the neighboring cell in the neighboring cell list is a neighboring cell configured with the specified location group as a configuration object. In general, the list of neighbors of the specified location group for the broadcast channel and the list of other locations other than the specified location group may be configured differently for the neighbor list of the broadcast channel. For each location group, the neighbor list for the traffic channel can be configured to be the same, and is the same as the neighbor list of the multi-site co-cell. It should be noted that, in the embodiment of the present invention, "the neighbor list for the broadcast channel" can be understood as another expression of "the neighbor list broadcasted through the broadcast channel", "the neighbor list for the traffic channel". It can be understood as another way of expressing "a list of neighbors transmitted through a traffic channel".

In this embodiment, preferably, the specified location group may be an edge location group of the multi-site common cell. The base station controller may configure the edge location group in the multi-site common cell to allow the neighboring area information on the BCCH to be broadcasted, and deliver the neighboring area information of the edge location group on the BCCH in the first system message broadcasted to ensure that the The idle terminals in the edge location group can initiate measurement and reselection of the neighbor cells, while the idle terminals of other location groups do not need to initiate neighbor cell measurement and reselection. Wherein, the edge location group may be multiple, and the respective neighboring regions may be different. For example, in a multi-site common cell in a high-speed rail scene, the location groups are arranged along the railway line, and the edge location group is two. The neighboring areas of the left edge location group and the right edge location group are different, and the base station broadcasts the left and right edge location groups respectively. Corresponding neighboring area information.

Referring to FIG. 5, a schematic diagram of the application of the above method provided on the railway according to the embodiment is illustrated by taking a 3G system as an example. The multi-site common cell is deployed on the railway in the figure, including five location groups. There is one location group at the location a and location c of the multi-site common cell boundary, and there are 3 locations at the location b in the multi-site common cell. Location group, location group 1 at location a has neighbor 1 on BCH, and neighbors 1 and 2 on TCH, location group 5 at location c has neighbor 2 on BCH, and neighbors on TCH 1 and 2, position groups 2, 3 and 4 at position b have neighbors 1 and 2 on the TCH.

When the base station broadcasts the first system message on the BCH of the location group 1, the cell description of the neighboring cell 1 is included; when the first system message is broadcasted on the BCH of the location group 5, the cell description of the neighboring cell 2 is included; When the second system message is broadcast on the BCHs of 3 and 4, the neighboring area information is not included; this can ensure that the terminal can be reselected to the neighboring area 1 at the location a, and can be reselected to the neighboring area 2 at the location c, in the cell The intermediate position b is as far as possible in position b.

At the same time, in order to ensure that the mobile phone in the service state and the high-speed mobile can quickly switch, the system message sent in the dedicated mode is required to include all the neighboring cells, so that the fast-moving mobile phone can switch to the adjacent neighbor in time. On the district. The system messages sent on the traffic channel can generally be system messages 5, 5bis, 5ter, and the like. The third system message broadcast by the base station on the TCH of any one of the multi-site common cells includes the information of the neighboring area 1 and the neighboring area 2 to ensure that The terminal in the service state can perform neighbor cell measurement and handover regardless of the location group, so as to avoid the terminal to quickly move to the edge location group but lack the neighbor information, and cannot initiate the handover to affect the service, thereby improving the switching effect and improving the switching effect. user experience.

For the multi-site common cell scenario covered by the railway, since the chain coverage is often used, the location group located at the edge of the multi-site common cell is physically connected to the neighboring cell, and the location group and the neighboring cell located inside the multi-site common cell are physically When the terminal accesses the location group at the edge of the multi-site common cell, it is desirable to switch to the neighboring cell. When the terminal accesses the location group within the multi-site common cell, it is not required to switch to the neighboring cell. However, if the prior art scheme is adopted, the terminals in the same multi-site common cell have the same reselection or handover capability, and the terminals in different location groups cannot have different reselection or handover capabilities, and the mobility management capability is poor. .

In the foregoing method, the first system message that carries the neighboring cell information of the specified location group is broadcast by the base station in the scenario of the multi-site common cell, and the idle terminal only receives the neighbor described in the first system message after receiving the message. The measurement is performed in the area, and the other neighboring areas of the multi-site common cell are not measured, so that the idle terminal can only be reselected in the measured neighboring area, which can meet the reselection requirement of the terminal in the specific location group, and is enhanced. user experience.

Further, the base station may not allow other location groups except the specified location group to send neighbor information through the broadcast channel, so that idle terminals in other location groups do not initiate neighbor measurement, thereby avoiding unnecessary reselection. For example, an idle terminal that is in a multi-site co-cell can be avoided from reselecting to a neighbor of a multi-site common cell.

In addition, the base station may send neighboring cell information of all location groups on the TCH to ensure that the terminal in the service state can initiate neighbor cell measurement and handover if it quickly moves to the edge location group of the multi-site common cell in the service process, and It will not affect the business and the business will not be interrupted.

And transmitting the measurement report to the base station control node, where the base station control node performs a handover decision according to the measurement report.

The base station control node determines whether the location group currently in the service state is a specified location group, and if yes, determines whether the terminal in the service state is triggered to switch to the neighboring cell according to the neighboring area measurement result.

In the LTE system, the handover decision based on the measurement report can also be performed by the eNodeB, and the decision process is similar to the decision process of the base station control node.

For each location group, the neighbor list for the traffic channel can be configured to be the same, and is the same as the neighbor list of the multi-site common cell. In this embodiment, the specified location group is preferably an edge location group of the multi-site common cell.

The method in any of the foregoing method embodiments may be implemented in the foregoing base station provided by the embodiment. The specific implementation process is described in the method embodiment, and details are not described herein again.
