Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for scheduling a combined service.
Background
The combined service includes voice service and packet switched ps (packet switch) service, and the existing resource allocation strategy of the combined service is to allocate the combined service to R4 carrier (one carrier resource specified by the protocol) preferentially, and allocate the combined service to H carrier (another carrier resource specified by the protocol) if the R4 carrier resource is insufficient. Currently, when a resource allocation strategy allocates carrier resources for a combined service, different carrier resources are allocated for a voice service and a packet switched PS service, and a specific scheduling manner is to use corresponding carrier resources to schedule the voice service and the PS service each time scheduling is reached.
However, the above-mentioned method and scheduling method for allocating carrier resources for combinational services have the following problems:
1) when a large amount of combined services are accessed, because different carrier resources are allocated to the voice service and the PS service by the existing resource allocation strategy, the combined services occupy more resources, which can cause the R4 carrier to be easily congested, the voice service can only try to access the H carrier after the R4 carrier is congested, and abnormal phenomena such as noise, single pass and the like can occur after the voice service is accessed to the H carrier because the H carrier interference is larger than the R4 carrier interference;
2) after the access of the voice service and the PS service on the R4 carrier fails, the access on the H carrier is attempted, and a large amount of resources of the H carrier are occupied after the access, which affects the call completing rate of the PS service of other users.
In order to ensure voice service perception and simultaneously improve the utilization rate of R4 carrier resources, a resource allocation strategy of releasing a PS service and then establishing the voice service is sometimes adopted in the current network, but the scheme can increase the time delay of voice service establishment and influence the voice service perception of a user, the PS service needs to be accessed again after the voice service is released, and the perception of the user using the PS service can be influenced to a certain extent.

Detailed Description
The method and apparatus for scheduling combinational services provided by the present invention are described in more detail below with reference to the accompanying drawings and embodiments.
The voice service perception of the combined domain user is found to be poor in the time division multiplexing TDS network, and the perception of the single voice service is better under the same condition. Meanwhile, the combined domain user occupies more resources, and the network is more easily congested. In addition, during the call process, people usually pay little attention to the PS service, and want to quickly recover the experience of the PS service after the call is finished and the voice service is released.
Based on this, an embodiment of the present invention provides a method for allocating combined service resources, as shown in fig. 1, the method includes:
step 101, when a voice service and a PS service exist at the same time, the same carrier resources are allocated to the voice service and the PS service;
the physical layer allocates the same carrier resources for the voice service and the PS service which exist simultaneously, so that the occupation of a code channel cannot be increased due to the existence of the PS service.
102, in a voice call period, only using the carrier resources to schedule a voice service data packet in the call period;
in the conversation period of the voice, the PS service can not be released, so the PS service can be always on line.
Step 103, in the silent period of the voice, when the voice service data packet and the PS service data packet having the silent period need to be transmitted, the carrier resources are used to simultaneously schedule the voice service data packet and the PS service data packet having the silent period, and when only the PS service data packet needs to be transmitted, the carrier resources are used to schedule the PS service data packet.
Research has shown that when people communicate by telephone, the one-way conversation time is usually only 40% or less of the total communication time, and the other about 60% of the time is the period of silence in the listening party's speech and communication. The silent period is generally not sent by voice service data packets, only one silent insert packet is sent every 160ms, if PS service data transmission is scheduled in the silent period of voice and voice data transmission is scheduled in the talk period of voice, wireless channel resources can be fully utilized on the premise of not increasing physical resources, and the resource utilization rate is provided.
In the embodiment of the present invention, when the same carrier resources are allocated to the voice service and the PS service, the manner of determining the allocated carrier resources may adopt an existing manner, such as preferentially allocating R4 carriers, and if the R4 carrier resources are insufficient to allocate H carriers, of course, other carrier resource allocation manners may also be adopted.
The embodiment of the invention keeps the PS service which is already carried out by the user in the combined domain on line under the condition of not increasing the physical layer resource occupation, limits the transmission of the PS service data when the voice data is transmitted, and transmits the PS service in the voice silent period, thereby effectively improving the resource utilization rate and effectively avoiding the carrier congestion.
In the embodiment of the present invention, when a combinational service is established (a voice service and a PS service exist simultaneously), the same carrier resources are allocated to the voice service and the PS service, which specifically includes:
when a voice service is established, allocating carrier resources for the voice service;
for at least one PS service established before the voice service is established, maintaining the connection of each established PS service, and reallocating carrier resources which are the same as the voice service to each PS service, wherein the PS service established before may use the carrier resources which are different from the voice service, so the PS services need to be reallocating when the voice service is established;
for at least one PS service established simultaneously with the voice service, allocating carrier resources which are the same as the voice service to each PS service;
and for at least one PS service which is newly established before the voice service is not released after the voice service is established, allocating the same carrier resources as the voice service to each PS service.
And when the voice service is released, the resources are reconfigured to recover the PS service resources, and because the PS is kept online in the process and does not need to be accessed again, the experience of the PS service can be recovered quickly.
Preferably, for the voice service and the PS service existing simultaneously, the method further comprises:
after the voice service is released, allocating carrier resources for the online PS service again;
and scheduling the PS service data packet by using the reallocated carrier resources each time when the scheduling period is reached.
Of course, instead of performing resource allocation again, the originally allocated carrier resources may be used to schedule the PS service packets each time the scheduling period is reached.
The voice service is usually a single voice service, one or more PS services existing simultaneously with the voice service may be provided, and when there are multiple PS services existing simultaneously with the voice service, it is preferable to allocate the same carrier resource as the voice service to each PS service;
in the silent period of voice, as long as it involves using carrier resources to schedule PS service data packets, no matter whether the voice service data packets and PS service data packets in the silent period are scheduled simultaneously using carrier resources, or the PS service data packets are scheduled only using carrier resources:
and for each PS service, scheduling the PS service data packet by using the carrier resources according to a mode of alternate scheduling, so that each PS service obtains the time for sending the data packet.
Taking the combination of voice and single PS services as an example, the following detailed comparison of the resource allocation strategies before and after optimization:
in the existing resource allocation scheme, carrier resources of 2 basic wireless unit BRUs are allocated to a single voice uplink and a single voice downlink respectively, and a combined service is usually allocated to an R4 carrier, which limits the PS service rate therein, generally to 16K, so that 4 BRUs are allocated to a combined voice and single PS service uplink and downlink, and if there are multiple PS services, more BRUs need to be occupied. There are 16 BRUs in 1 timeslot in the TDS system, and if it is a combination of voice and single PS, 1 timeslot can accommodate up to 4 users.
According to the optimized resource allocation scheme, the combined service and the single voice use the same physical resources, and 2 BRUs are respectively allocated in the uplink and the downlink, so that at most 8 users can be accommodated in 1 time slot, the resource utilization rate of the R4 carrier is higher, and the congestion condition of a hot spot area can be effectively relieved.
The control plane of the current RNC allocates a transport channel carrying service data and each available transport format for the data link layer of the local service plane, each transport channel and its corresponding transport format form a transport format combination, and all the transport formats form a transport format set.
Preferably, the embodiment of the present invention restricts the transmission of PS service data when controlling the transmission of voice data by a transport format combination, and the specific manner is to allocate corresponding transport channels to the voice service and the PS service, and pre-configure a transport format combination set including a plurality of transport format combinations, where each transport format combination is used to indicate a transport format corresponding to each assigned transport channel, and the transport format combination set does not include a transport format combination for simultaneously scheduling a voice service data packet in a talk period on a transport channel corresponding to the voice service and scheduling a PS service data packet on a transport channel corresponding to the PS service by using the same carrier resource; then
In the conversation period of the voice, selecting a corresponding transmission format combination from the transmission format combination set, and scheduling a voice service data packet in the conversation period on a transmission channel corresponding to the voice service by using the carrier resource;
and when the voice service data packet and the PS service data packet in the silence period need to be transmitted in the voice silence period, selecting a corresponding transmission format combination from the transmission format combination set, using the carrier resource, scheduling the voice service data packet in the silence period on a transmission channel corresponding to the voice service and scheduling the PS service data packet on a transmission channel corresponding to the PS service, when only the PS service data packet needs to be transmitted, selecting a corresponding transmission format combination from the transmission format combination set, and scheduling the PS service data packet on the transmission channel corresponding to the PS service by using the carrier resource.
Preferably, the method further comprises: and informing the UE of the configuration of the optimized transport format combination set.
The following takes the combined service composed of voice service and single PS service as an example, and gives a preferred embodiment of the combined service scheduling method of the present invention.
AMR speech is divided into 3 substreams, the voice service data packet lengths of the 3 substreams sent simultaneously every 20ms transmission time interval during a voice call period are 81bit, 103bit, 60bit respectively, there is generally no data to send during a silence period, a silence insertion packet is sent only every 160ms, the voice service data packet length on the corresponding substream 1 is 39bit, and there is no data on the latter two substreams.
When the combinational service exists, the control plane of the RNC allocates a transport channel for carrying service data and each available transport format to the data link layer of the local service plane, and usually corresponding signaling needs to be transmitted in addition to the transmission of the voice service and the PS service data. Typically one transport channel (TrCH) is allocated for signaling, three coordinated transport channels (TrCH1, TrCH2, TrCH3) are allocated for the three substreams for AMR speech, and one transport channel (TrCH) is allocated for a single PS service. As shown in fig. 2, these transport channels are multiplexed onto one coded composite transport channel CCTrCH; and allocating a transport format combination set to the CCTrCH, wherein the set comprises transport format combinations that can be selected when each radio frame air interface schedules to send data.
Under a typical business scenario:
the transport format that can be selected for the signaling SRB transport channel is as follows:
(TF0:0 x 148) indicating that no signaling is scheduled on the SRB transport channel;
(TF1:1 × 148) indicating that 148bit of signaling is scheduled on the SRB transport channel;
the transport format that can be selected for the voice Speech transport channel is as follows:
(TF0:0 x 81, TF0:0 x 103, TF0:0 x 60) indicating that subflow 1 is not scheduled on TrCH1, subflow 2 is not scheduled on TrCH2, and subflow 3 is scheduled on TrCH3, corresponding to the case where no voice traffic packets are transmitted during the silence period;
(TF1:1 × 39, TF0:0 × 103, TF0:0 × 60) indicating that substream 1 of 39 bits is scheduled on TrCH1, substream 2 is not scheduled on TrCH2, substream 3 is not scheduled on TrCH3, corresponding to the case where voice service packets inserted during the silence period need to be transmitted;
(TF2:1 × 81, TF1:0 × 103, TF1:0 × 60) indicating that substream 1 of 81 bits is scheduled on TrCH1, substream 2 of 103 bits is scheduled on TrCH2, substream 3 of 60 bits is scheduled on TrCH3, corresponding to the situation that the voice service data packets during the talk period need to be transmitted;
the transport format that can be selected for the PS traffic transport channel is as follows:
(TF0:0 x 336) indicating that PS traffic packets are not scheduled on the PS traffic transport channel;
(TF1:1 × 336) indicating that 336 bits of PS traffic packets are scheduled on the PS traffic transport channel.
Before optimization, the uplink and downlink transport format combination set transport format combination allocated by the RNC is an exhaustive combination of a transport format selectable by a signaling transport channel, a transport format selectable by a voice transport channel, and a transport format selectable by a PS service transport channel, which is specifically shown in table 1. The transport format combination set of the uplink and downlink allocated by the RNC after optimization is shown in table 2.
Table 1 traditional combined set of voice and single PS service transport formats
Table 2 optimized combined set of voice and single PS service transport formats
When the optimized RNC allocates the uplink and downlink transmission format combination set, for the transmission format with voice data transmission, the transmission format of the PS service can only use allocated TF 0; for the transport format without voice transmission, the transport format of PS service may use TF0 and TF 1.
The above-mentioned transport format combination TFC configuration can ensure that when there is voice data transmission, PS service data cannot be transmitted, and PS service transmission is scheduled in the voice silent period.
As shown in fig. 3, when determining that there is a service establishment, the RNC determines whether a combined service establishment is currently formed, and if so, allocates an optimized physical layer resource and transport format combination set, that is, allocates the same carrier resource for the voice and each PS service, allocates the transport format combination set shown in table 2, and performs local service plane configuration at the control plane; executing a radio link reconfiguration process with a base station NodeB, executing a radio bearer establishment process with UE, and then adopting the method of the embodiment of the invention to carry out combined service scheduling transmission.
The service side of RNC dispatches data once at transmission time interval, when data dispatching is carried out, if voice service data packet of conversation period is received from core network, only TFCI5 (no accompanying signaling data transmission at present) or TFCI6 (accompanying signaling data transmission at the same time) can be selected when transmission format combination selection is carried out; when the voice service data packet of the talk period is not received from the core network or the voice service data packet inserted in the silence period is received (only substream 1 of the 3 voice substreams has data, and the packet length is 39 bits), the selection can be made in the rest combinations according to whether the accompanying signaling and the PS data need to be transmitted.
The configuration conditions of voice and single PS service are only given, and when a plurality of PS services are provided, each PS service can obtain the time for sending data by a mode of scheduling each PS service in turn in the voice silent period.
The invention provides an optimized resource allocation strategy, when a combined service is established, a physical layer allocates physical resources which are the same as single voice, namely, code channel occupation is not increased; .
In the combined service scheduling method provided by the invention, the physical layer uses the same physical layer code channel allocation scheme for PS services and single voice, i.e. the occupation of carrier resources (code channels) is not increased, and the congestion of R4 carriers can be effectively avoided; when a user has an uplink and downlink transmission format combination set of a combined service RNC distributed coded combined transmission channel CCTrCH, a transmission format combination for simultaneously sending data by voice data and PS service data does not appear in the transmission format combination set, release is not initiated to the existing PS service when the voice service is accessed, the transmission of the PS service data is limited when the voice data transmission is controlled through the transmission format combination, the PS service is transmitted in a voice silent period, and the PS service does not need to be accessed again when the voice service is released, so that the experience of using the PS service by the user is ensured.
