Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of interference bypassing method and equipment.
Background technology
Along with the development of the communication technology, in communication system, there is the network coexisted scene of different mobile communication standard, heterogeneous networks has different characteristics, and the terminal equipment in corresponding heterogeneous networks also has different characteristics.For example, GSM(Global System of Mobile communication, global system for mobile communications) network and LTE(Long Term Evolution, Long Term Evolution) frequency spectrum resource that network using is adjacent covers the same area jointly, the macro base station of GSM network is deployed in the equidistant GSM terminal equipment of high building position far away, conventionally the distance between GSM terminal equipment and macro base station is more than 30 meters, and the cellulor base station of LTE network may be deployed in indoor, cellulor network scenarios for example, conventionally the distance between LTE terminal equipment and cellulor base station is very near, can be less than 3 meters, the region that cellulor base station covers is the part in macro base station coverage area.The 900MHz(Mega Hertz of GSM terminal equipment, megahertz) frequency range maximum transmission power is 2 watts, and 33 dBms (dBm), 1800MHz frequency range maximum transmission power are 1 watt, i.e. 30dBm, and the transmitting power of LTE terminal equipment 23dBm only.

GSM network described in the embodiment of the present invention and the network coexisted simulated scenario of LTE just schematically illustrate, and this is not limited in any way.
The embodiment of the present invention provides a kind of interference bypassing method, suppose to be applied to the GSM network shown in Fig. 2 and the network coexisted simulated scenario of LTE, suppose that the first base station is the first macro base station, the second base station is the first cellulor base station, first terminal equipment is a GSM terminal equipment, the second terminal equipment is a LTE terminal equipment, as shown in Figure 3, comprising:
User can operate a GSM terminal equipment, by a GSM terminal equipment, carries out speech business or data service, and a GSM terminal equipment sends uplink service request message to the first macro base station.
Generally, the first macro base station can judge according to the received power of the arrival bearing of the uplink service request message of a GSM terminal equipment and a GSM terminal equipment, transmitting power distance and the deflection of a GSM terminal equipment and the first macro base station, then according to the current location of the location positioning of the first macro base station the one GSM terminal equipment.The first macro base station can also send the indication that a GSM terminal equipment reports the positional information of self to a GSM terminal equipment, require a GSM terminal equipment by the GPS(Global Positioning System of self, global positioning system) or the positional information of the GSM terminal equipment measured by other means report the first macro base station.In the first macro base station and GSM network, other macro base stations adjacent with the first macro base station can be measured the reference signal of a GSM terminal equipment transmitting simultaneously, according to the relative time of advent of reference signal, and the positional information of the first macro base station self, can measure the current location of a GSM terminal equipment.
In described positional information table, record the positional information of the macro base station in GSM network, the coverage of each cellulor base station in the coverage of each macro base station and described LTE network in the positional information of the cellulor base station in LTE network, described GSM network, the neighboring BS relationship between macro base station and cellulor base station.When telegon receives after the positional information of a GSM terminal equipment, obtain the positional information table of local storage.
When telegon receives after the positional information of a GSM terminal equipment, because the position of a GSM terminal equipment is in the coverage of the first macro base station, telegon is determined as the first cellulor base station according to the cellulor base station adjacent with the first macro base station of recording in described positional information table.
The invention process example assumes the first macro base station is adjacent with the first cellulor base station, performs step 306.
Telegon receives the positional information of a described GSM terminal equipment, and has obtained after the first cellulor base station range according to the positional information table of this locality storage, judges that a GSM terminal equipment is whether in the first cellulor base station range.If a GSM terminal equipment is not in the first cellulor base station range, telegon continues to monitor the position of a GSM terminal equipment and whether a GSM terminal equipment sends upward signal to the first macro base station in the first cellulor base station range, until a GSM terminal equipment moves to the coverage of the first macro base station, finishes monitoring outward.If a GSM terminal equipment is in the first cellulor base station range, telegon starts interference workaround.
The invention process example assumes the one GSM terminal equipment is in the first cellulor base station range, and telegon starts interference workaround.Execution step 307.
Terminal equipment can carry out speech business or data service, and the frequency resource that speech business takies base station is less than the frequency resource that data service takies base station.Telegon takies business that frequency resource that the frequency resource of the first macro base station, LTE terminal equipment in the first cellulor base station range take the first cellulor base station, the first macro base station provide for the GSM terminal equipment in the first macro base station coverage and the first cellulor base station according to the GSM terminal equipment in the first macro base station coverage and determines rollback base station for the business that the LTE terminal equipment in the first cellulor base station range provides.
Concrete, GSM terminal equipment in the first macro base station is this first macro base station coverage provides the less speech business of frequency resource that takies the first macro base station, the first cellulor base station is that the LTE terminal equipment in this first cellulor base station range provides the more data service of frequency resource that takies the first cellulor base station, can to select the first macro base station be rollback base station to telegon, make the first macro base station carry out frequency resource rollback, in like manner, GSM terminal equipment in the first macro base station is this first macro base station coverage provides the more data service of frequency resource that takies the first macro base station, the first cellulor base station is that the LTE terminal equipment in this first cellulor base station range provides the less speech business of frequency resource that takies the first cellulor base station, can to select the first cellulor base station be rollback base station to telegon, make the first cellulor base station carry out frequency resource rollback.
Especially, GSM terminal equipment in the first macro base station is this first macro base station coverage provides the less speech business of frequency resource that takies the first macro base station, but the number of users of frequency resource that takies the first macro base station is more, make the first macro base station reach heavy duty state, the frequency resource that the GSM terminal equipment in the first macro base station coverage takies the first macro base station reaches the limiting value of the frequency resource of the first macro base station, and the first cellulor base station provides the more data service of frequency resource that takies the first cellulor base station for the LTE terminal equipment in this first cellulor base station range, but the number of users of frequency resource that takies the first cellulor base station is less, make the first cellulor base station when light-load state, it is rollback base station that telegon can be selected the first cellulor base station, make the first cellulor base station carry out frequency resource rollback.In like manner, LTE terminal equipment in the first cellulor base station is this first cellulor base station range provides speech business, but the first cellulor base station has reached heavy duty, when the frequency resource that the LTE terminal equipment in the first cellulor base station range takies the first cellulor base station reaches the limiting value of frequency resource of the first cellulor base station, it is rollback base station that telegon can be selected the first macro base station, makes the first macro base station carry out frequency resource rollback.
The invention process example assumes, when described rollback base station is the first cellulor base station, performs step 308 to step 3019, when described rollback base station is the first macro base station, as shown in Figure 4.
The first macro base station receives to be forbidden after response message, forbids that the first macro base station sends uplink service request response to a GSM terminal equipment, sends the response message of forbidding response message of the first macro base station to telegon.
Step 3010, telegon send to disturb to the first cellulor base station evades message.
3GPP(3rd Generation Partnership Project, third generation partner program) agreement is defined in LTE network frequency resource is divided to frequency resource with resource block mode.Described interference is evaded message and is used to indicate the Resource Block number that the first cellulor base station needs rollback, so that the Resource Block number that the number of the Resource Block of message indication equates is evaded in the first cellulor base station rollback and described interference.The adjacent frequency resource of frequency resource that described the first cellulor base station needs the Resource Block of rollback to use for the first macro base station adjacent with the first cellulor base station.
The first cellulor base station receives described interference evades after message, and the Resource Block number that the number of the Resource Block of message indication equates is evaded in rollback and described interference.Example, conventionally can there be 50 Resource Block the first cellulor base station of LTE network, the coverage of supposing the first cellulor base station can be that radius is the coverage of 3 meters, when a GSM terminal equipment is in the coverage of the first cellulor base station, described interference is evaded message and is indicated the first cellulor base station to need 25 Resource Block of rollback, and the first cellulor base station receives described interference and evades 25 Resource Block of rollback after message.It should be noted that, the number of the Resource Block of rollback with need the coverage of base station of rollback Resource Block relevant, because while building for the first time in base station, the coverage of different base station constructions is different, so the Resource Block number of different base station rollbacks is different, the number of the larger Resource Block that needs rollback of the coverage of base station is fewer.The embodiment of the present invention just schematically illustrates described rollback Resource Block number, to this restriction.
So, when a GSM terminal equipment carries out speech business or data service with higher transmitting power to the first macro base station transmission upward signal in the coverage of the first cellulor base station, the first cellulor base station is carried out to disturb and is evaded message success rollback Resource Block, has effectively evaded the interference of GSM terminal equipment to the first cellulor base station.
At a LTE terminal equipment, carrying out data service or speech business, or a LTE terminal equipment prepares to carry out data service or speech business, the one LTE terminal equipment receives described interference to be evaded after message, makes a LTE terminal equipment not use the Resource Block of rollback.
Telegon receives the interference of the first cellulor base station to be evaded after response message, to the first macro base station, sends and permits response message, and indication allows the first macro base station to send uplink service request response to a GSM terminal equipment.
Step 3015, the first macro base station send uplink service request response to a GSM terminal equipment.
The one GSM terminal equipment receives after uplink service request response, can carry out speech business or data service.
It should be noted that, the one GSM terminal equipment and a LTE terminal equipment can carry out data service or speech business simultaneously, also data service or speech business be can carry out respectively, as long as avoid a GSM terminal equipment to send upward signal with higher transmitting power to the first macro base station in the coverage of the first cellulor base station, speech business or the interference of data service to the first cellulor base station carried out.After a GSM terminal equipment end data business or speech business, perform step 3017.
After a GSM terminal equipment end data business or speech business, the first cellulor base station receives to remove to disturb evades message, the Resource Block number of the first cellulor base station reduction rollback, described releasing interference is evaded message and is used to indicate the Resource Block number that the first cellulor base station need to be reduced, and described rollback Resource Block number equates with reduction Resource Block number.
The embodiment of the present invention provides a kind of interference bypassing method, suppose to be applied to the GSM network shown in Fig. 2 and the network coexisted simulated scenario of LTE, suppose that the first base station is the first macro base station, the second base station is the first cellulor base station, first terminal equipment is a GSM terminal equipment, the second terminal equipment is a LTE terminal equipment, as shown in Figure 4, comprising:
Step 405, telegon determine that according to described positional information table the cellulor base station adjacent with the first macro base station is as the first cellulor base station.
The invention process example assumes the one GSM terminal equipment is in the first cellulor base station range, and telegon starts interference workaround.When described rollback base station is the first macro base station, perform step 407 to step 4013.
Step 407, telegon send to disturb to the first macro base station evades message.
Gsm protocol is defined in GSM network frequency resource is divided to frequency resource in channel mode.Described interference is evaded message and is used to indicate the channel number that the first macro base station needs rollback, so that the channel number that the number of the channel of message indication equates is evaded in the first macro base station rollback and described interference.The adjacent frequency resource of frequency resource that described the first macro base station needs the channel of rollback to use for the first cellulor base station adjacent with the first macro base station.
The first macro base station receives described interference to be evaded after message, and the channel number that the number of the channel of message indication equates is evaded in rollback and described interference.Example, conventionally the first macro base station of GSM network can have 4 to 8 channels, the coverage of supposing the first macro base station can be that radius is the coverage of 30 meters, when a GSM terminal equipment is in the coverage of the first cellulor base station, described interference is evaded message and is indicated the first macro base station to need 3 channels of rollback, and the first macro base station receives described interference and evades 3 channels of rollback after message.The embodiment of the present invention just schematically illustrates described backoff channel number, to this restriction.
Step 4010, the first macro base station send to disturb to telegon evades response message.
So, the one GSM terminal equipment can be evaded use and disturb the frequency domain resource of the first cellulor base station to carry out speech business or data service in the coverage of the first cellulor base station, the one LTE terminal equipment also can carry out data service or speech business simultaneously, has effectively evaded the interference of GSM terminal equipment to the first cellulor base station.
After a GSM terminal equipment end data business or speech business, perform step 4011.
Step 4011, telegon send to remove to disturb to the first macro base station evades message.
After a GSM terminal equipment end data business or speech business, the first macro base station receives to remove to disturb evades message, the channel number of the first macro base station reduction rollback, described releasing interference is evaded message and is used to indicate the channel number that the first macro base station need to reduce, and described backoff channel number equates with reduction channel number.
It should be noted that, the interference bypassing method described in the embodiment of the present invention also can be suitable for and other networks, and the GSM network described in the embodiment of the present invention and LTE network are not limited.
