It is appreciated that structure shown in Fig. 4 is only to illustrate, group calling monitoring terminal 10 may also include more than shown in Fig. 4 Perhaps less component or with the configuration different from shown in Fig. 4.Each component shown in Fig. 4 can use hardware, software Or combinations thereof realize.

On the basis of the above, the disclosure also provides a kind of computer readable storage medium, the computer-readable storage medium Matter includes computer program, and group calling monitoring is whole the computer program controls the computer readable storage medium when running where End executes the residence reselecting realized by group calling monitoring terminal.

Based on the studies above, the disclosure provides a kind of residence reselecting, this method can by group calling monitoring terminal, with And base station and the realization of cluster core net in broadband cluster system.

The letter of the adjacent cell of current area and current area of the group calling monitoring terminal monitoring of RRC Idle state where it Number quality judges whether to need from current area gravity treatment to any Target cell.Wherein, Target cell is a certain of current area A adjacent cell, for example, signal quality can be higher than to some adjacent cell of current area as Target cell.

Please refer to Fig. 5, when decision set exhales monitor terminal to need gravity treatment to Target cell, execute cell reselection it Before, group calling monitoring terminal, base station and cluster core net execute following steps respectively.

S21, group calling monitoring terminal judge whether the Target cell that the base station where detecting current area is sent System information and the group for monitoring group exhale configuration information.

In the disclosure, system information may include Physical Cell Identifier, downlink frequency point number, downlink bandwidth etc..Monitor group The group for the group that the group of group exhales configuration information to refer to that group calling monitoring terminal is monitored exhales configuration information.Group exhales the configuration information to may include The wireless spread-spectrum technology that group wails code, group exhales load identification, group that the packet data polymerized protocol parameter of carrying, group is exhaled to exhale carrying is joined Number, group exhale Logic Channel Identifier of carrying etc..

After Target cell is established and monitors group, the base station where current area could obtain and send Target cell System information and the group for monitoring group exhale configuration information.Thus, if group calling monitoring terminal detects the base station where current area The system information of the Target cell of transmission and the group for monitoring group exhale configuration information, and group calling monitoring terminal then can be small according to target The system information gravity treatment in area exhales configuration information to continue to supervise monitoring group to Target cell, and according to the group for monitoring group It listens.So that it is guaranteed that group calling monitoring terminal will not interrupt the monitoring for monitoring group in cell reselection process.

In the case where Target cell does not set up and monitors group, the base station where current area can not obtain Target cell System information and the group for monitoring group exhale configuration information.Thus, what the base station where current area can not send Target cell is System information and the group for monitoring group exhale configuration information.Correspondingly, group calling monitoring terminal can not detect the current area place Base station send the Target cell system information and monitor group group exhale configuration information.

Wherein, according to the communicating requirement between the base station where current area and group calling monitoring terminal, Target cell is System information and the group for monitoring group exhale configuration information that can be encapsulated in the message for meeting communicating requirement between the two.For example, mesh The system information for marking cell and the group for monitoring group exhale configuration information that can carry in the configuration broadcast message of adjacent cell.Accordingly Ground, the adjacent cell configuration broadcast that group calling monitoring terminal can decide whether that the base station where detecting current area is sent disappear Breath, if the adjacent cell configuration broadcast message that the base station where detecting current area is sent, and adjacent cell configuration is wide The group for broadcasting the system information in message including Target cell and monitoring group exhales configuration information, then determines to detect current area institute Base station send Target cell system information and monitor group group exhale configuration information.If current area institute is not detected Base station the adjacent cell configuration broadcast message or adjacent cell configuration broadcast message that send in not including Target cell System information and the group for monitoring group exhale configuration information, then the target for determining that the base station where current area is not detected is sent is small The system information in area and the group for monitoring group exhale configuration information.Wherein, adjacent cell configuration broadcast message can be with periodicity sending.

In view of the Target cell that after Target cell is established and monitors group, the base station where current area may be will acquire System information and monitor group group exhale configuration information carry out periodicity sending, such as sent by release cycle, if issue The detection cycle of period and group calling monitoring terminal mismatches, if release cycle is not completely overlapped with detection cycle, then, it is also possible to Because the base station that detection cycle does not cause group calling monitoring terminal to fail where detecting current area in release cycle is sent Target cell system information and monitor group group exhale configuration information.

The system information and monitoring of the Target cell of the base station transmission where current area is not detected in group calling monitoring terminal In the case that the group of group exhales configuration information, group calling monitoring terminal then passes through the base station where current area for the small of Target cell At least one of area's mark and tracing area mark TAI, and group wail code and are forwarded to cluster core net.

Following step S22 and step S23 are please referred to, group calling monitoring terminal can be by the cell ID of Target cell and tracking At least one of area identification TAI, and group wail code and are sent to the base station where current area, and then are forwarded by the base station To cluster core net.

The cell ID of Target cell and tracing area are identified at least one of TAI by S22, group calling monitoring terminal, with And group wails code and is sent to the base station where current area.

In a kind of example, group calling monitoring terminal can be identified the cell ID of the Target cell and tracing area At least one of TAI and group exhale local number portability in the non access stratum NAS message that instruction carries out cell reselection.Described Current area passes through the base station that the NAS message is sent to where the current area by the common signal channel eated dishes without rice or wine.

Group calling monitoring terminal is using the common signal channel eated dishes without rice or wine, such as Physical Random Access Channel (Physical Random Access Channel, PRACH), common control channel (Common Control Channel, CCCH) etc. sends out NAS message The base station to where current area is sent, so as to save interface-free resources.

The communicating requirement between base station where group calling monitoring terminal and current area, NAS message can be encapsulated In the message for meeting communicating requirement between the two.For example, can newly define one meets group calling monitoring terminal and current area institute Base station between communicating requirement message, NAS message is carried in the message newly defined, and then is transmitted to current area The base station at place.

S23, the base station where current area receive cell ID and the tracking for the Target cell that group calling monitoring terminal is sent At least one of area identification TAI, and group wail code, will be in the cell ID of Target cell and tracing area mark TAI At least one, and group wail code be forwarded to cluster core net.

For the terseness of description, later by least one in the cell ID of Target cell and tracing area mark TAI It is a, and organize catchword code and be referred to as target information.The target information is the cell ID and tracking area for including the Target cell At least one of domain identifier TAI, and group wail code.

Base in the case where target information carries in the NAS message that instruction carries out cell reselection, where current area It stands, which is forwarded to cluster core net.

According to the communicating requirement between the base station where current area and cluster core net, weight can be carried out to NAS message New encapsulation, between the base station that NAS message is encapsulated in where meeting current area and cluster core net in the message of communicating requirement. For example, the message for meeting the base station where current area and the communicating requirement between cluster core net can newly be defined, by NAS Message carries in the message of the new definition, and then is transmitted to cluster core net.

S24, cluster core net receive current area where base station forwarding target information, according to the target information into Row establishes the confirmation interaction for monitoring group in the Target cell, and the base station where making the current area executes step S25.

S25, the base station where current area obtains the system information of the Target cell and the group of monitoring group is exhaled and matched Confidence is ceased and is broadcasted.

In view of the system for causing group calling monitoring terminal to fail the Target cell that the base station where detecting current area is sent The reason of information and the group for monitoring group exhale configuration information may monitor group not set up in Target cell, it is also possible to for detection Period is not in release cycle.Thus, step S24 may include: the cluster core net judge the Target cell whether The monitoring group has been established, if it is determined that the monitoring group has been established in the Target cell, notifies the current area institute Base station obtain the system information of the existing Target cell and monitor the group of group and exhale configuration information and broadcasted.If Determine not setting up the monitoring group in the Target cell, the base station where the target information and the Target cell Signalling exchange is carried out, establishes the monitoring group in the Target cell, is made described in the base station where the current area obtains The system information of Target cell and the newly-established group for monitoring group are exhaled configuration information and are broadcasted.

Wherein, cluster core net can be recorded to the cell for monitoring group has been established, for example, monitoring has been established in record The cell ID and tracing area of the cell of group identify TAI.Cluster core net passes through judgement after receiving target information Whether record has cell ID or tracing area in target information to identify to determine monitoring whether has been established in Target cell Group (in the case where record has cell ID or tracing area in target information to identify, determines built in Target cell It is vertical to monitor group, in the case where not recording the cell ID and tracing area mark in target information, determine small in target Area, which is not set up, monitors group).

When the base station where current area and the base station where Target cell are different base stations, where current area Base station can obtain the system information and new foundation of Target cell after Target cell is established and monitors group in the following manner The group of monitoring group exhale configuration information and broadcasted: cluster core net receive Target cell where the target that sends of base station The system information of cell and the newly-established group for monitoring group exhale configuration information, by the system information of Target cell and newly-established Monitor group group exhale configuration information to be transmitted to current area where base station so that base station where current area obtains target The system information of cell and the newly-established group for monitoring group are exhaled configuration information and are broadcasted.

Base when the base station where current area and the base station where Target cell are same base station, where current area (base station i.e. where Target cell) is stood after Target cell is established and monitors group, can be directly obtained Target cell is System information and the newly-established group for monitoring group are exhaled configuration information and are broadcasted, without being forwarded by cluster core net.

In order to ensure interactive reliability, cluster core net, which establish in Target cell according to target information, monitors group Confirmation interaction, so that the base station where current area is obtained the system information of Target cell and is monitored the group of group and exhale with confidence Before ceasing and being broadcasted, cluster core net can carry out legitimate verification to target information, and property is verified if legal, then root It carries out establishing the confirmation interaction of monitoring group in Target cell according to target information, it is small that the base station where making current area obtains target The system information in area and the group for monitoring group are exhaled configuration information and are broadcasted.Property verifying if legal does not pass through, then abandons institute State target information.

Wherein, legitimate verification may include: the integrality of verification object information.If verification show that target information is complete, Then determine that legitimate verification passes through, if verification show that target information is imperfect, determines that legitimate verification does not pass through.

In the case where target information carries in the NAS message that instruction carries out cell reselection, cluster core net is received After the NAS message, the legitimate verification to target information can be realized by carrying out legitimate verification to the NAS message.? After NAS message legitimate verification passes through, cluster core net build in Target cell according to the target information in the NAS message The vertical confirmation interaction for monitoring group, the base station where making current area obtain the system information of Target cell and monitor group Group is exhaled configuration information and is broadcasted.

Wherein, cluster core net is determining that cluster core net can be in the case where Target cell does not set up and monitors group Signalling exchange is carried out according to the target information in NAS message and the base station where Target cell, which may include: collection Base station where group's core net notice Target cell is established in Target cell monitors group, and the base station where Target cell is in target Cell, which is established, monitors group, distributes group call resource, and cluster core net monitors having been established the cell ID of the Target cell of group It is recorded with tracing area mark TAI.

In view of tracing area mark TAI may correspond to multiple cells, tracing area mark is carried in NAS message In the case where TAI, cluster core net can according to tracing area identify TAI formed cell list, and then in cell list Base station where each cell carries out confirmation interaction respectively, so that it is guaranteed that the base station where each cell in cell list, which is established, to be had Monitor group.

Wherein, in order to save interface-free resources, the base station where current area can be incited somebody to action by the point-to-multipoint channel eated dishes without rice or wine The system information of the Target cell obtained and the group for monitoring group exhale configuration information to be broadcasted.

Optionally, the group of the system information of Target cell and monitoring group can be exhaled configuration by the base station where current area Information is broadcast periodically.For example, the base station where current area can be by the system information of Target cell and monitoring group The group of group is exhaled configuration information to carry in the configuration broadcast message of adjacent cell and is broadcast periodically.

S26, group calling monitoring terminal receive the base station where the current area in the current cell broadcasts, described mesh The system information for marking cell and the group for monitoring group exhale configuration information.

Wherein, if the group of the system information of Target cell and monitoring group is exhaled configuration information by the base station where current area It carries in the configuration broadcast message of adjacent cell and is broadcasted, group calling monitoring terminal then can receive to where current area The adjacent cell configuration broadcast message of base station broadcast obtains the system letter of Target cell from the adjacent cell configuration broadcast message Breath and the group for monitoring group exhale configuration information.

S27, group calling monitoring terminal according to the system information gravity treatment of the Target cell to the Target cell, and according to institute The group for stating the monitoring group of Target cell exhales configuration information to continue to monitor the monitoring group.So that it is guaranteed that group calling monitoring terminal exists The monitoring for monitoring group will not be interrupted in cell reselection process.

In order to more clearly illustrate the implementation process of the disclosure, the difference in same base station is now occurred with cell reselection Between cell and both scenes between the different community across base station occur, respectively to ensuring in the disclosure in cell reselection mistake The unbroken residence reselecting of monitoring for monitoring group is further illustrated in journey.

Scene one, turning back to refering to fig. 1, it is assumed that cell 1 and cell 2 belong to base station 1, the group calling monitoring of RRC Idle state Terminal resides in cell 1 originally, as the signal that group calling monitoring terminal moves to reach cell 1 covers edge, into the letter of cell 2 Number coverage area, the signal matter of group calling monitoring terminal monitoring cell 1 (current area) and cell 2 (adjacent cell of current area) Amount show that the signal quality of cell 2 is better than the signal quality of cell 1, and cell 2 meets cell re-selection conditions.So, group calling monitoring Terminal is therefore, it is determined that need gravity treatment to cell 2 (Target cell).

Assuming that the group of the system information of cell 2 and monitoring group is exhaled in base station 1 matches after cell 2 is established and monitors group Confidence breath carries in Neighbor Cell Config (adjacent cell configuration) broadcast message.It is newly fixed that group calling monitoring terminal passes through RRC Nas Information Transfer (transmission of the RRC Idle state information) message of justice carries the NAS message newly defined Cell Reselection Indicton, by least one in the cell ID of cell 2 and the tracing area of cell 2 mark TAI It is a, and monitor corresponding group of group and exhale local number portability in NAS message.Base station 1 uses the UE Message newly defined Transfer (group calling monitoring terminal information transfer) message carries NAS message.

So, Fig. 6 is please referred to, before executing cell reselection, group calling monitoring terminal, base station 1 and cluster core net Interaction flow it is as follows.

S31, group calling monitoring terminal judge whether to detect the Neighbor Cell Config that base station 1 is sent in cell 1 Broadcast message.

If group calling monitoring terminal detects the Neighbor Cell Config broadcast message that base station 1 is sent in cell 1, It and include that the system information of cell 2 and the group of monitoring group are exhaled with confidence in Neighbor Cell Config broadcast message Breath, then the system information gravity treatment in group calling monitoring terminal direct basis Neighbor Cell Config broadcast message is to cell 2, and exhale configuration information to continue to monitor the monitoring of group according to the group for monitoring group, process terminates.

Disappear if base station 1 is not detected in group calling monitoring terminal in the Neighbor Cell Config broadcast that cell 1 is sent Breath, or detect that Neighbor Cell Config broadcasts the message, but Neighbor Cell Config broadcasts the message In including cell 2 system information and monitor group group exhale configuration information, then execute S32.

S32, group calling monitoring terminal pass through the common signal channel eated dishes without rice or wine in cell 1, as PRACH sends the RRC Nas newly defined For Information Transfer message to base station 1, it is new fixed to carry in RRC Nas Information Transfer message The NAS message Cell Reselection Indicton of justice, carry in NAS message cell 2 cell ID and cell 2 with Corresponding group of catchword code of monitoring group of at least one of track area identification TAI and group calling monitoring terminal monitoring.

S33 uses the UE newly defined after base station 1 receives RRC Nas Information Transfer message Message Transfer message carries the NAS message in RRC Nas Information Transfer message, and by UE Message Transfer message is transmitted to cluster core net.

S34 after cluster core net receives UE Message Transfer message, obtains the NAS message of its carrying, Completeness check is carried out to judge the legitimacy of NAS message to NAS message.If NAS message legitimate verification does not pass through, lose The NAS message is abandoned, process terminates.If NAS message legitimate verification passes through, continue process, executes S35.
