Description
Technical field
The present invention relates to the capacity of communication system field, be meant a kind of method, system and terminal that in cordless communication network, increases number of users especially.
Background technology
Cordless communication network is one of focus of present Research on Communication Technology.Along with the evolution and the development of wireless communication technology, (Internet Protocol, IP) packet switch is a main development trend at present for broadband and Internet protocol.At present third generation cordless communication network (3
RdGeneration Mobile CommunicationsSystem, 3G), in the research of 3.5G and 4G, higher throughput and the spectrum efficiency of Geng Gao have become one of emphasis of research.
Can realize the spectrum efficiency of higher capacity and Geng Gao by number of ways, comprise the introducing and the realization of various diversity techniques, wherein a kind of approach is exactly more effectively to improve the effective bandwidth that is used to transmit data in the communication bandwidth.In cordless communication network, carry various control commands by control channel usually, carry effective business datum by Traffic Channel.Like this, how to design a cordless communication network efficiently, under the prerequisite that guarantees the normal effectively running of cordless communication network, reduce the expense of control channel as far as possible, thereby improve the occupation proportion of Traffic Channel, improving the throughput of whole cordless communication network, is important studying a question all the time.
In the cordless communication network of support package exchange at present, one of main effect of control channel is to be used for load-bearing allocation message, carries the descending and/or ascending resource of cordless communication network for user's assignment in this assignment message.Because each user has sudden, distributed characteristics in the request of data of downlink or uplink in the cordless communication network, therefore, be to carry out respectively at uplink and downlink according to user's request at each user's resource allocation.That is to say, when cordless communication network has downlink data to send to the user, be this user's allocation of downlink channel resource just, to notify the user by the down channel assignment message be the resource of its distribution to cordless communication network then, and the user takies reception and the processing that respective resources is carried out downlink data according to this down channel assignment message; When the user has upstream data to send to cordless communication network, the request cordless communication network is its Resources allocation, to notify the user by the up channel assignment message be the resource of its distribution to cordless communication network then, and the user takies processing and the transmission that respective resources is carried out upstream data according to this up channel assignment message.
Fig. 1 shows existing assignment message structural representation, as shown in Figure 1, comprise in the assignment message: the PF that is used to identify the packet format of distribution, the NodeID of the resource that sign is distributed, whether sign uses the Extended of expansion transmission mode, whether sign is used the Supplemental of the pattern of augmenting and is identified the assigned resources Duration of effective time, wherein, PF takies the length of 6 bits, NodeID takies the length of 6 bits, Extended takies the length of 1 bit, Supplemental takies the length of 1 bit, and Duration takies the length of 1 bit.Described assignment message both can be the up channel assignment message, also can be the down channel assignment message.
(mode that generally adopts packet of every transmission all to send an assignment message is come the assigned resources for the user for Orthogonal Frequency Division Multiplexing, OFDM) cordless communication network at present OFDM.But for voice-over ip (Voice over Internet Protocol, VoIP) professional, because its length of data package is all smaller, if packet of every transmission all sends an assignment message, then can generate a large amount of assignment messages, make the expense of cordless communication network increase greatly.Like this, for the VoIP business, generally adopt at present the mode of sticky assignments, promptly after the assignment, the resource long-term of distributing to the voip user is effective, the structural representation of sticky assignments message as shown in Figure 2, compare with general assignment message, owing to give user's resource long-term effective by the sticky assignments distribution of messages, therefore, no longer comprise the Duration field in sticky assignments message, all the other structures and assignment message are basic identical.
In the OFDM cordless communication network, each NodeID is corresponding to the combination of a series of subcarriers.Owing to the number of subcarriers that is comprised in the OFDM cordless communication network is fixed, therefore, the NodeID quantity that comprises in the OFDM cordless communication network is directly related with the number of subcarriers that NodeID comprised.As shown in Figure 3, when comprising 2048 NodeID in the OFDM cordless communication network, the NodeID that comprises in the assignment message needs to use
Bit could be represented; When comprising 64 NodeID in the OFDM cordless communication network, the NodeID that comprises in the assignment message only need use
Bit just can be represented.Like this, generally, basic number of subcarriers that NodeID comprised can not be very little, otherwise, can increase the length and the expense of assignment message.Owing to the granularity of minimum NodeID, be that the number of subcarriers that is comprised can not be too little, for the voip user, to distribute the NodeID of a minimum at least, normally 16 subcarriers or 25 subcarriers.
In sticky assignments process, a voip user in use between in some time slot fixedly take a pairing resource of NodeID.But because the enhancing day by day of VoIP speech coding technology at present, the data traffic that needs interface aloft to transmit reduces day by day, like this, a voip user in use between in, even fixedly take a NodeID who comprises minimum number of subcarriers, also still have very big resource redundancy.At present, for fear of bigger resource redundancy, how to transmit voip user's packet with lower power, so that the voip user uses the more time resource can finish the transmission of packet, distribute to that a voip user comprises the NodeID of minimum number of subcarriers and the redundant resource that is available thereby fill up; And give the user of other non-sticky assignments, and then promote the throughput of whole cordless communication network with remaining power division.
Though filled up by power control mode and to have distributed to the redundant resource that NodeID that the voip user comprises minimum number of subcarriers is available, but, because there is the sum of errors uncertainty in power control, still there is certain redundancy in the resource of distributing to the voip user, and when all users are the voip user in cordless communication network, and make remaining power have no idea to be utilized, cause the waste of power resource.Because voip user's quantity of supporting of cordless communication network is subjected to the restriction of the NodeID quantity that this cordless communication network comprises, like this, total number of users of cordless communication network support is restricted, thereby has influenced the capacity of whole cordless communication network.
