Abstract

A method of controlling user equipment in a wireless communications network, the method comprising: producing different system information for different groups of user equipment based on characteristics of the user equipment, sending the system information to said user equipment, and indicating to which group of the user equipment the system information is addressed.

Claims

1. A method of controlling user equipment in a wireless communications network, the method comprising:

producing different system information for different groups of user equipment based on characteristics of the user equipment;

sending the system information to said user equipment; and

indicating to which group of the user equipment the system information is addressed,

wherein, said step of producing comprises including mobility of the user equipment in a group information element of scheduling information inside a Master Information Block,

wherein the method further comprises;

sending the system information in a System Information Block, wherein the System Information Block is part of said Master Information Block and including said information element in said Master Information Block; and

evaluating the System Information Blocks and deciding to which of the groups of the user equipment particular System Information Block is applicable.

2. The method according to claim 1, comprising sending an information element including the indication to which group of the user equipment the system information is addressed.

3. The method according to claim 1, wherein, in said step of producing, function of the user equipment is considered.

4. The method according to claim 1, wherein the information element identifies more than one group of user equipment to which the particular system information is addressed.

5. A network node for use in a wireless communications network comprising a plurality of user equipment located in at least one cell and the network node comprises:

a function for producing different system information for different groups of said user equipment based on characteristics of the user equipment and for indicating to which group of the user equipment the system information is addressed;

a sender for sending the system information and said indication to said user equipment; and

an evaluation unit configured to evaluate the system information and decide to which of the groups of the user equipment particular system information is addressed,

wherein, said function for producing comprises a function that includes mobility of the user equipment in a group information element of scheduling information inside a Master Information Block.

7. The network node according to claim 5, configured to send the system information in a System Information Block, wherein the System Information Block is part of said Master Information Block and to include said information element in said Master Information Block.

8. The network node according to claim 5, wherein the network node is a Radio Network Controller or eNodeB.

6. A network node comprising a register for storing information about different groups of the user equipment, wherein the groups are defined based on characteristics of the user equipment.

9. A wireless communications network comprising:

a first plurality of network nodes; and

a second plurality of user equipment,

wherein the nodes are configured to control the user equipment by sending to said user equipment system information, and the user equipment belongs to at least one of at least two groups, wherein allocation to a group is based on characteristics of said equipment and at least one of said nodes is configured to produce different system information for different groups of said user equipment and to evaluate the system information and decide to which of the groups of the user equipment particular system information is addressed, and to send the system information to said user equipment with an indication to which group of the user equipment the system information is addressed,

wherein, said producing of different system information for different groups of said user equipment comprises including mobility of the user equipment in a group information element of scheduling information inside a Master Information Block.
