Description

Channel management method, device and base station controller

Technical Field

Background

Global System for Mobile Communication, abbreviated as: GSM) is currently the most widely used mobile telephone standard, and from a user perspective, GSM has the major advantage that users can choose between higher digital voice quality and low cost messaging.

In a GSM network, when a user performs a data service, two timeslot reassignment actions of uplink and downlink channel adaptive adjustment and load balancing exist: triggering time slot reassignment judgment when a Base Station Controller (BSC) receives an uplink or downlink Protocol Data Unit (PDU) or acquires multi-time slot capability, and determining whether to trigger uplink and downlink channel adaptive adjustment according to a judgment result: and the BSC periodically (4.5 s) triggers the time slot reassignment so as to achieve load balance among Packet Data Channels (PDCHs) and enable users to obtain better Data service experience.

In the above-mentioned technology, the time slot reassignment is triggered when a trigger condition (event trigger or periodic trigger) is satisfied, and most of GSM networks are instant messaging services, which have a short duration and cause frequent time slot reassignment, thereby causing network burden and possibly introducing a call drop risk.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic structural diagram of a base station controller according to a first embodiment of the present invention. An embodiment of the present invention provides a base station controller, as shown in fig. 1, where the base station controller includes: a first processor 10 and a first transmitter 20 connected to the first processor 10.

Wherein, the first processor 10 is configured to determine a service characteristic of the PDCH according to a data volume carried by the PDCH; determining whether to trigger time slot reassignment according to the service characteristics of the PDCH; if so, the first transmitter 20 is triggered to send a timeslot reassignment message to the mobile station.

A Temporary Block Flow (TBF) is used to carry packet services between the base station controller and the mobile station, and when data needs to be transmitted between the base station controller and the mobile station, an uplink TBF and/or a downlink TBF is established.

The data volume carried by the PDCH comprises the uplink continuous accumulated data volume of the PDCH and/or the data volume in the downlink buffer of the PDCH. The uplink continuous accumulated data volume of the PDCH is the byte total volume of continuous transmission of the uplink TBF carried on the PDCH, represents the total volume of the accumulated sending data of the uplink TBF continuously in the data transmission process, and has the calculation formula as follows: the continuous cumulative data volume + of the uplink of the PDCH + = uplink packet size. When the uplink TBF enters a delayed release state or an extended inactive period, clearing the uplink continuous accumulated data volume of the PDCH; the data volume in the downlink buffer of the PDCH is the buffered data volume of the downlink TBF that has been carried on the PDCH, that is, represents the total amount of bytes buffered in the buffer in the downlink direction, specifically, the data volume of the downlink packet service data that has not been sent to the mobile station through the downlink TBF carried on the PDCH and that is received by the base station controller (excluding the sent but unacknowledged data volume), and the downlink packet service data of the PDCH is buffered in the buffer of the base station controller before being sent to the mobile station, and the calculation formula is: the data amount in the downlink buffer of the PDCH + = downlink packet size.

If the size of the uplink continuous accumulated data volume is 0, indicating that no uplink data transmission exists on the PDCH; similarly, if the size of the data amount in the downlink buffer is 0, it indicates that there is no downlink data transmission on the PDCH.

The determining, by the first processor 10, the service characteristic of the PDCH according to the calculated data amount carried by the PDCH may include: if the uplink continuous accumulated data volume of the PDCH is larger than a first preset threshold and the Count Value (CV) of the uplink data block of the PDCH is a preset Value, determining that the uplink service requirement of the PDCH is large; or, if the uplink continuous accumulated data volume of the PDCH is greater than the first preset threshold and the CV of the uplink data block of the PDCH is less than the preset value, determining that the uplink service demand of the PDCH is small; or, if the uplink continuous accumulated data volume of the PDCH is less than or equal to the first preset threshold, determining that the uplink service demand of the PDCH is small; or if the continuous uplink accumulated data volume of the PDCH is zero, determining that the PDCH has no business requirement.

And comparing the size relationship between the uplink continuous accumulated data volume of the PDCH and a first preset threshold, and simultaneously judging the size relationship between the CV of the uplink data block and a preset value, namely determining whether the CV of the uplink data block is the maximum, wherein under the normal condition, if the CV is smaller than the preset value, the fact that no more traffic is transmitted subsequently is indicated, and uplink priority allocation is not needed.

On the basis, the first processor 10 determines the service characteristics of the PDCH according to the calculated data amount carried by the PDCH, and may further perform the following operations: if the data volume in the downlink buffer of the PDCH is larger than a second preset threshold, determining that the downlink service requirement of the PDCH is large; or, if the data volume in the downlink buffer of the PDCH is zero, determining that the PDCH has no downlink service requirement; or, if the data amount in the downlink buffer of the PDCH is less than or equal to the second preset threshold, determining that the downlink service requirement of the PDCH is small.

In this embodiment, the first processor 10 may determine the uplink service requirement of the PDCH only according to the uplink continuous cumulative data volume of the PDCH; or determining the downlink service requirement of the PDCH only according to the data volume in the downlink buffer of the PDCH; and determining the uplink and downlink service requirements of the PDCH according to the uplink continuous accumulated data volume of the PDCH and the data volume in the downlink buffer of the PDCH, wherein the method does not limit the uplink and downlink service requirements.

It should be noted that, the first preset threshold here is a traffic threshold that allows preferential allocation of uplink; the second preset threshold is a buffer flow threshold allowing to preferentially distribute downlink; and typically the preset value is 15.

Through the judgment of the uplink continuous accumulated flow of the PDCH, the data volume in the downlink buffer of the PDCH, the first preset threshold, the preset value and the second preset threshold, the instant communication service can be screened out, the redundant time slot reconfiguration of the instant communication service is avoided, and the call drop risk and the signaling burden are reduced.

Further, when the first processor 10 executes the step of determining whether to trigger timeslot reassignment according to the service characteristics of the PDCH, it is specifically configured to: determining the current service attribute of the PDCH according to the service characteristics of the PDCH; and determining whether to trigger time slot reassignment according to the determined current service attribute of the PDCH and the last service attribute of the PDCH, wherein the last service attribute of the PDCH is the service attribute determined for the PDCH immediately adjacent to the current service attribute.

When the first processor 10 determines the current service attribute of the PDCH according to the service feature of the PDCH, it may specifically perform: if the uplink service requirement of the PDCH is large, and the downlink service requirement of the PDCH is small or the PDCH has no downlink service requirement, determining the current service attribute of the PDCH as uplink priority; or, if the uplink service requirement of the PDCH is small or no uplink service requirement and the downlink service requirement of the PDCH is large, determining that the current service attribute of the PDCH is downlink priority; or, if the uplink service requirement of the PDCH is small, and the downlink service requirement of the PDCH is small or no downlink service requirement exists, determining that the current service attribute of the PDCH is a neutral service; or, if the PDCH has no uplink service requirement and the downlink service requirement of the PDCH is small, determining that the current service attribute of the PDCH is a neutral service; or, if the uplink service requirement of the PDCH is large and the downlink service requirement of the PDCH is large, determining that the current service attribute of the PDCH is a neutral service.

The determining whether to trigger timeslot reassignment according to the determined current service attribute of the PDCH and the last service attribute of the PDCH may include: if the current service attribute of the PDCH is downlink priority and the last service attribute of the PDCH is uplink priority or neutral service, determining that the service attribute of the PDCH is reassigned as downlink priority; or, if the current service attribute of the PDCH is uplink-first and the last service attribute of the PDCH is downlink-first or neutral service, determining to reassign the service attribute of the PDCH as uplink-first.

In this embodiment, whether to perform timeslot reassignment is determined according to service attributes of PDCHs determined twice in the neighborhood. When the current service attribute of the determined PDCH is the same as the last service attribute of the PDCH or the current service attribute of the determined PDCH is a neutral service, no adjustment is carried out; otherwise, the determined current service attribute of the PDCH is taken as the standard for reassigning the service attribute of the PDCH. For example, if the last service attribute of the PDCH is uplink-first and the determined current service attribute of the PDCH is uplink-first or neutral service, the service attribute of the PDCH does not need to be reassigned, i.e., the timeslot reassignment does not need to be triggered; if the last service attribute of the PDCH is an uplink priority or neutral service and the determined current service attribute of the PDCH is a downlink priority, reassigning the service attribute of the PDCH to be the downlink priority, namely triggering time slot reassignment; the rest of the scenes are analogized, and the description is omitted here.

Fig. 2 is a schematic structural diagram of a second embodiment of a base station controller according to the present invention. As shown in fig. 2, in the present embodiment, the base station controller may further include a receiver 30, and the receiver 30 is connected to the first processor 10 and the first transmitter 20 respectively.

The use of the receiver 30 is described in detail below with several specific implementation scenarios:

in a specific implementation scenario, the receiver 30 is configured to trigger the first processor 10 to determine a service characteristic of a Packet Data Channel (PDCH) according to a Data volume carried by the PDCH when receiving a Protocol Data Unit (PDU);

in another specific implementation scenario, the receiver 30 is configured to trigger the first processor 10 to determine a service characteristic of the PDCH according to a data volume carried by the PDCH when receiving the downlink PDU;

in another specific implementation scenario, the receiver 30 is configured to trigger the first processor 10 to determine a service characteristic of the PDCH according to a data volume carried by the PDCH when acquiring the multi-slot capability.

The above three specific implementation scenarios are triggered by the receiver 30 to execute the determination of the traffic characteristics of the PDCH according to the amount of data carried by the PDCH, by means of event triggering. In addition, the first processor 10 may also be triggered periodically to perform the determination of the traffic characteristics of the PDCH according to the amount of data carried by the PDCH. The period may be 4.5 seconds, or may be other values, which is not limited in the present invention.

In the embodiment of the invention, the base station controller is triggered to execute the time slot reassignment to carry out the channel management by various modes, so that the adaptive adjustment and the load balance of the uplink and downlink channels are more optimized.

Further, since there is a probability loss phenomenon in the timeslot reassignment message, on the basis of the above, the receiver 30 may be further configured to trigger the first transmitter 20 to retransmit the timeslot reassignment message to the mobile station if the response message sent by the mobile station is not received after the preset time arrives. In the embodiment, the time slot reassignment protection is added, and the probability of successful time slot reassignment is improved.

In addition, after the first transmitter 20 sends the timeslot reassignment message to the mobile station, the receiver 30 does not receive the response message sent by the mobile station after the preset time arrives, and if N3105 does not overflow and the Transport Format Indication (TFI) resource on the PDCH is not occupied, the timeslot reassignment message is allowed to be retransmitted within a certain number of times. If the first sender 20 is sending a timeslot reassignment message or a Downlink reassignment message, when the original time for setting a Relative Reserved Block Period (RRBP) identifier arrives, the RRBP identifier is set in the sent data Block to wait for an uplink Packet Downlink Ack/Nack response.

If the receiver 30 receives a Packet downlink ack/Nack on a new channel at a corresponding uplink time, it considers that the timeslot reassignment message or the downlink unidirectional reconfiguration process is successfully ended;

if the receiver 30 does not receive the packetdown Ack/Nack on the new channel at the corresponding uplink time, and the number of retransmissions count of the first transmitter 20 is less than 2, retransmitting the timeslot reassignment message or the downlink reassignment message, and adding 1 to the number of retransmissions count in the first transmitter 20;

if the corresponding uplink time, the receiver 30 does not receive the Packet downlink ack/Nack on the new channel, and the retransmission count is greater than or equal to 2 times, or N3105 overflows during the process, or it is found that the TFI resource on the original channel has been allocated during the retransmission, and any one of the conditions is satisfied, then the reassignment is considered to be failed, and the timeslot reassignment message or the downlink reassignment message is not retransmitted, and the reassignment procedure is ended.

Generally, the abbreviation NC (Network Control, NC) is used to indicate Network Control, and if the mobile station is in NC0 mode, the base station controller selects the Network side Control parameter NC2 switch to be on through the parameter, and when the mobile station supports NC2 mode, the mobile station enters NC2 mode.

In addition, under the General Packet Radio Service mobility management (GMM) Ready state, the mobile station working in the NC2 mode will periodically report the Packet measurement report, which results in the times of reassignment increasing, thereby increasing the load of the Common Control Channel (CCCH); on the other hand, due to the compatibility problem of the mobile station, the uplink reassignment success rate is deteriorated. For a large number of small-flow users in a GSM network, the effect of network intelligent reselection in the NC2 mode is weak, and the influence on user perception is small, but the common problem of the NC2 mode continuously influences network indexes.

For the above reasons, referring to fig. 3, an embodiment of the present invention provides a base station controller, including: a second processor 40 and a second transmitter 50 connected to the second processor 40, wherein the second processor 40 is configured to determine a traffic characteristic of the PDCH according to the amount of data carried by the PDCH; determining whether to control the mobile station allocated on the PDCH to perform mode switching according to the service characteristics of the PDCH; if so, and if the mobile station is determined to be in NC0 mode and the network side control parameter NC2 switch is on, then the second transmitter 50 is triggered to transmit a first packet measurement command to the mobile station to notify the mobile station to enter NC2 mode.

Specifically, the second processor 40 first determines the traffic characteristics of the PDCH according to the data volume carried by the PDCH, where the data volume carried by the PDCH includes at least one of the following data or any combination thereof: the continuous uplink accumulated data volume of the PDCH, the count value CV of the uplink data block of the PDCH, the data volume in the downlink buffer of the PDCH and the length of the downlink buffer of the PDCH; and determining whether to control the mobile station allocated on the PDCH to perform mode switching according to the service characteristics of the PDCH, wherein the second processor 40 controls the mobile station to perform mode switching only when the mobile station is in an NC0 mode and a network-side control parameter NC2 switch is on, and triggers the second transmitter 50 to transmit a first Packet Measurement Order (PMO) to the mobile station to notify the mobile station to enter an NC2 mode.

In the embodiment of the invention, the base station controller determines the service characteristics of the PDCH through the data volume carried by the PDCH, and further determines whether to control the mobile station to carry out mode switching, thereby realizing the reduction of signaling burden in a network and the improvement of network performance.

The following description explains how the second processor 40 determines the service characteristics of the PDCH according to the data volume carried by the PDCH through several specific application scenarios; and determining whether to control the mobile station allocated on the PDCH to implement mode switching according to the service characteristics of the PDCH.

In an application scenario, the second processor 40 is specifically configured to: if the uplink continuous accumulated data volume of the PDCH received by the uplink TBF is determined to be larger than the preset uplink large service threshold, the mobile station is controlled to carry out mode switching, namely a second transmitter 50 is triggered to transmit a first packet measurement command to the mobile station. Specifically, when the uplink continuous accumulated data volume of the PDCH is greater than a preset uplink large traffic threshold, a person skilled in the art may understand that the uplink traffic demand of the PDCH is large; and determining to control the mobile station to carry out mode switching according to the uplink service characteristics of the PDCH. The preset uplink large service threshold may be the same as or different from the first preset threshold.

In another application scenario, the second processor 40 is specifically configured to: if the number of times that the CV of the uplink data block received by the uplink TBF is greater than the third preset threshold is determined to exceed the fourth preset threshold, the mobile station is controlled to perform mode switching, that is, the second transmitter 50 is triggered to transmit the first packet measurement command to the mobile station. Specifically, when the CV exceeds a fourth preset threshold for a number of times that the CV is greater than a third preset threshold, a person skilled in the art may understand that the uplink service requirement of the PDCH is determined to be large; and determining to control the mobile station to carry out mode switching according to the uplink service characteristics of the PDCH. The third preset threshold may be the same as or different from the preset value.

In another application scenario, the second processor 40 is specifically configured to: if the data volume in the downlink buffer of the PDCH is determined to be greater than the preset large downlink traffic threshold, the mobile station is controlled to perform mode switching, that is, the second transmitter 50 is triggered to transmit the first packet measurement command to the mobile station. Specifically, when the data amount in the downlink buffer of the PDCH is greater than the preset downlink large service threshold, a person skilled in the art may understand that the downlink service requirement in the PDCH is determined to be large; and determining to control the mobile station to carry out mode switching according to the downlink service characteristics of the PDCH.

In another application scenario, the second processor 40 is specifically configured to: if the length of the downlink buffer of the PDCH is determined to be greater than the fifth preset threshold, the mobile station is controlled to perform mode switching, i.e., the second transmitter 50 is triggered to transmit the first packet measurement command to the mobile station. Specifically, when the length of the downlink buffer of the PDCH is greater than the fifth preset threshold, a person skilled in the art may understand that the downlink service requirement of the PDCH is determined to be large; and determining to control the mobile station to carry out mode switching according to the downlink service characteristics of the PDCH.

It should be noted that any preset value in the present invention is set according to actual requirements, and is not limited herein.

In the above embodiment, after the base station controller selects the network control mode as the NC2 mode through the parameters for the mobile station in the NC0 mode (the mobile station supports the NC2 mode), it defaults that all mobile stations (even if the mobile station supports the NC2 mode) maintain the NC0 mode, and first, distinguish between large traffic and small traffic, such as the higher-occupancy instant communication service in the GSM network, because the service duration is shorter, the effect of network intelligent reselection in the NC2 mode is weak, and the impact on the user perception is not great, but the common problem of the NC2 (in the GMM Ready state, the mobile station working in the NC2 mode periodically reports packet measurement reports, which results in a multiplied increase in the number of reassignments and increases the load of the CCCH; due to the compatibility problem of the mobile station, the uplink reassignment success rate is deteriorated) continuously affects the network index; the mobile station with large flow and long duration enters into NC2 mode to ensure better network performance.

Further, the mobile station is in NC2 mode, and the second transmitter 50 is further operable to: upon release of the TBF on the PDCH, a second packet measurement command is sent to the mobile station to notify the mobile station to enter NC0 mode. And releasing the TBF on the PDCH to indicate that no uplink and downlink data are transmitted in the PDCH, and controlling the mobile station in the NC2 mode to be switched to the NC0 mode by the base station controller so as to reduce the reassignment times and reduce the CCCH load.

Wherein, the switching between the NC0 mode and the NC2 mode of the mobile station is shown in fig. 4 and fig. 5, fig. 4 is a signaling diagram of the mobile station switching from the NC0 mode to the NC2 mode in the third embodiment of the base station controller of the present invention; fig. 5 is a signaling diagram of a mobile station switching from NC2 mode to NC0 mode in a third embodiment of the base station controller of the present invention.

As shown in fig. 4, the mobile station 41 is in NC0 mode, and an uplink TBF is established between the mobile station 41 and the base station controller 42 for data transmission. The handover procedure is described below, where the mobile station 41 is in NC0 mode 401-404 and in NC2 mode after 404:

403. Mobile station 41 sends a packet control acknowledgment to base station controller 42.

404. The base station controller 42 sends a first packet measurement order message to the mobile station 41.

After receiving the packet measurement command from the base station controller 42 through the PACCH, the mobile station 41 waits for the time to periodically send the packet measurement report, and then, 405 periodically sends the packet measurement report.

405. Mobile station 41 sends a packet measurement report to base station controller 42.

The signaling interaction between the mobile station 41 and the base station controller 42 is performed on a Packet Associated Control Channel (PACCH).

As shown in fig. 5, the mobile station 51 is in NC2 mode, and a downlink TBF is established between the mobile station 51 and the base station controller 52 for data transmission. The handover procedure is described below, where the mobile station 51 is in NC2 mode 501-503 and in NC0 mode after 503:

501. base station controller 52 sends data to mobile station 51.

502 is performed after the mobile station 51 receives the last transmitted downlink Radio Link Control (RLC) data block of the wheeled circulation indication sent by the base station controller 52.

502. Mobile station 51 sends a packet downlink acknowledge message to base station controller 52.

503. The base station controller 52 issues a second packet measurement command message to the mobile station 51.

The above-mentioned signaling interaction between the mobile station 51 and the base station controller 52 is also performed on the PACCH.

In this embodiment, a second transmitter in the base station controller transmits a packet measurement command (a first packet measurement command message and/or a second packet measurement command message) to the mobile station, so as to implement switching of the mobile station between the NC0 mode and the NC2 mode, avoid the mobile station with low traffic volume from entering the NC2 mode, and improve network performance.
