Description

Method for controlling fast associated control channel paging, base station subsystem, system

technical field

The present invention relates to the communication field, in particular to a method for controlling Fast Associated Control Channel (FACCH) paging, a base station subsystem and a system.

Background technique

GSM-R (GSM-Railway, railway integrated digital mobile communication system) is based on the Global System for Mobile communications (GSM) public mobile communication technology, and develops together with GSM. A single platform can replace the existing multiple railway communication and control Systematic railway integrated digital mobile communication system.

Voice Group Call Service (VoiceGroupCallService, VGCS) and Voice Broadcast Service (VoiceBroadcastService, VBS) are a point-to-multipoint communication mode, which breaks through the limitations of point-to-point (P2P) communication and can quickly establish calls. After the VGCS/VBS service is established, the mobile station (MobileStation, MS) acts as a listener or speaker on the group call channel. When the mobile switching center (MobileSwitchingCenter, MSC) software supports the FACCH paging function (implementing R6 and above protocol versions) and the background configuration is "support FACCH paging", the MS on the P2P paging group call channel, then the MSC is in A The port sends a paging (PAGING) message, the message carries the paging information (PagingInformation) field, after the base station subsystem (BaseStationSystem, BSS) receives the paging message, all public control stations in the location area where the MS is located Channel (CommonControlCHannel, CCCH) sends common paging message and all activated group call channels send FACCH notification (carry paging information field) message, MS responds after receiving the paging message on the group call channel. As shown in Figure 1, the MSC sends a paging (PAGING) message on the A port, and the BSS has a FACCH notification (carrying the paging information field) message on the Um port.

When the MSC software does not support the FACCH paging function (that is, implements the protocol version below R6) or the MSC software supports the FACCH paging function but the background is configured as "do not support FACCH paging", the MS on the P2P paging group call channel, then The MSC sends a PAGING message on port A, which does not carry the PagingInformation field. After receiving the paging message, the BSS finds that the paging message does not carry the PagingInformation field. The general paging message is sent on the CCCH channel, and the MS on the group call channel cannot receive the paging message on the group call channel. As shown in Figure 2, the P2P paging of the MS on the group call channel fails at this time.

As can be seen from Figure 1 and Figure 2, when the MSC software does not support the FACCH paging function or the MSC background configuration is "not supporting FACCH paging", when P2P paging the MS on the group call channel, the MS cannot receive the group call channel. The paging message is received, resulting in call failure, which greatly reduces the service quality of the voice service and reduces the satisfaction of the user experience.

detailed description

The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

Embodiment one:

Please refer to Figure 3, the method for controlling fast associated control channel paging in this example includes the following steps:

After receiving the paging message, the base station controller (BaseStationController, BSC) judges whether the paging information field is carried in the received paging message;

If the received paging message does not carry the paging information field, the BSC will fill the paging information field in the paging message it delivers; send;

After receiving the paging message issued by the BSC, the base transceiver station (BaseTransceiverStation, BTS) sends the paging message on the corresponding channel according to whether the paging message carries the paging information field;

After receiving the paging message sent by the BTS, the mobile station MS responds to the paging message.

It can be seen from the above that in this example, even when the MSC software does not support the FACCH paging function or the MSC background configuration is "not supporting FACCH paging", the paging message sent by the MSC to the BSC does not carry the paging message. After receiving the information field, the BSC can add the paging information field to the paging message sent by it and send it to the BTS, and then send it to the MS on the group paging channel through the BTS to ensure the fast associated control channel The normal operation of paging improves the satisfaction of user experience, that is, the base station subsystem BSS in this example can independently control the FACCH paging function, which complements the MSC control, greatly improving the service quality of voice services, and thus improving user experience. experience.

Preferably, in this example, the content of the paging information field filled by the BSC in the paging message sent by the BSC may include: voice group call service mode VGCS or voice broadcast service mode VBS.

In this example, the BTS sends the paging message on the corresponding channel according to whether the received paging message carries the paging information field, including: after receiving the paging message sent by the BSC, the BTS judges whether the received paging message Whether the message carries the paging information field, if so, send the paging message on the public control channel and the activated group call channel, wherein the paging message sent on the public control channel is a normal paging message, The paging message sent on the group paging channel is the paging message carrying the paging information field; otherwise, the paging message is only sent on the common control channel.

Preferably, before the BSC in this example fills the paging information field in the paging message it sends, it also includes the step of judging whether to allow filling the paging information field in the paging message it sends, if not, then no Filling and sending directly; this function setting can further increase the controllability of the BSS, and the user can make specific choices according to the actual situation to further improve the user experience.

Preferably, before the MS responds to the received paging message, it may also include judging whether the service priority included in the paging message is greater than the group call priority, and if so, automatically respond to the paging message; otherwise, do not actively Instead of responding, let the user choose whether to respond. Specifically, judging whether the service priority included in the paging message is higher than the group call priority is judging that the enhanced MultiLevel Precedence and Preemption (eMLPP) priority included in the paging message is higher than the group call priority.

This example also provides a base station subsystem BSS that controls fast associated control channel paging, see Figure 4, including a base station controller BSC and a base transceiver station BTS, wherein,

The BSC includes a fast associated control channel paging control module (FACCH paging control module), and the FACCH paging control module is used to determine whether the paging message carries a paging information field after the BSC receives the paging message, as shown If the paging information field is not carried in the paging message, the paging information field is filled in the paging message issued by the BSC;

The base transceiver station BTS is used to send the paging message on the corresponding channel according to whether the paging message carries the paging information field after receiving the paging message delivered by the BSC.

This example also provides a system for controlling fast associated control channel paging, see Figure 5, including mobile switching center MSC, base station subsystem BSS, mobile station MS, base station subsystem BSS includes base station controller BSC and base transceiver station Device BTS, base station controller BSC comprises fast associated control channel paging control module (FACCH paging control module), wherein:

The MSC is used to send a paging message to the BSC;

The BSC is used to receive the paging message sent by the MSC, and is also used to send the paging message to the BTS; the FACCH paging control module is used to determine whether the paging message carries a paging message after the base station controller receives the paging message Paging information field, if the paging message does not carry the paging information field, then fill the paging information field in the paging message issued by the BSC;

The BTS is used to receive the paging message issued by the BSC; and is used to send the paging message on the corresponding channel according to whether the paging message carries the paging information field;

The MS is used to respond to the paging message sent by the BTS.

Preferably, the MS in this example also includes a priority judging module. Before the MS responds to the received paging message, the priority judging module judges whether the service priority included in the paging message is greater than the group call priority, and if so, notifies The MS responds to the paging message; otherwise, it needs to be confirmed by the user before deciding whether to notify the MS to respond.

Embodiment two:

In order to better understand the present invention, a complete process of initiating call paging, that is, responding to high paging paging will be further described below in this example.

Since the communication interface between the base station controller BSC and the mobile switching center MSC is the A interface, the communication interface between the BSC and the base station transceiver BTS is the Abis interface; the communication interface between the BTS and the mobile station MS is the Um interface, that is, the air interface, the following takes the completion of the above-mentioned paging and response process based on the above-mentioned interfaces as an example for description.

Assume that the MSC software in this example does not support the FACCH paging function or the MSC background configuration is "does not support FACCH paging". Please refer to Figure 6. At this time, the paging message sent by the MSC on the A interface does not carry paging information ( PagingInformation) field, after the base station subsystem BSS receives the paging message, it judges that the paging message does not carry the PagingInformation field, fills it autonomously according to the above method, and then sends the corresponding paging message on the corresponding channel, at this time The paging message sent by the BSS through the air interface carries the PagingInformation field, and the MS on the group paging channel can receive and respond to the paging message to ensure the normal progress of fast associated control channel paging. Please refer to Figure 7 for the specific implementation process:

701: MS on the P2P paging group call channel;

702: The MSC sends a paging message to the BSC on the A interface;

703: The BSC receives a paging message;

704: The FACCH paging control module of the BSC judges whether there is a PagingInformation field in the received paging message, if there is such a field, then go to step 705; otherwise, go to step 706;

705: Fill the PagingInformation field in the Abis interface paging message according to the PagingInformation field in the A interface paging message, and go to step 708;

706: The BSC judges whether the switch of "allowing to control FACCH paging" is turned on. If the switch is turned off, it does not fill the PagingInformation field in the paging message of the Abis interface, and goes to step 708; otherwise, goes to step 707;

707: The BSC autonomously fills the PagingInformation field in the Abis interface paging message;

708: The BSC sends a paging message to all BTSs in the location area where the MS is located through the Abis interface;

709: The BTS receives the paging message from the Abis interface;

710: The BTS judges whether there is a PagingInformation field in the paging message, if yes, then go to step 711; otherwise, go to step 712;

711: The BTS sends the FACCH notification message carrying the PagingInformation field on all activated group call channels of the cell (that is, the paging message on the group call channel);

712: The BTS sends a general paging message on the CCCH channel of the cell;

713: If the MS on the group paging channel receives the paging message, respond to the paging message according to the above method; otherwise, the P2P paging fails.

As can be seen from the above, the present invention realizes that under the condition that the MSC software does not support the FACCH paging function or the MSC background is configured as "does not support FACCH paging", the BSS independently controls the FACCH paging function, so that P2P successfully pages to the The MS on the group call channel ensures the service quality of voice services and improves user experience satisfaction.

The above content is a further detailed description of the present invention in conjunction with specific embodiments, and it cannot be assumed that the specific implementation of the present invention is limited to these descriptions. For those of ordinary skill in the technical field of the present invention, without departing from the concept of the present invention, some simple deduction or replacement can be made, which should be regarded as belonging to the protection scope of the present invention.
